In 2011, the security industry continued to grow rapidly. The video surveillance industry's 23% growth rate exceeded the GDP growth rate by nearly 2 times. Rapid growth represents an increase in the importance of the industry and the rapid innovation of new technologies. At the 2011 Shenzhen Ambrance Fair, the endless stream of new technologies and new ideas gave everyone a sense of “squandering for fascinating eyes”. Among the many hot words, we are more familiar with the "high-definition", "networking", "smart", "standardization", "security", there are many we are not familiar with "960H", "2M+", "HD-SDI "," "Cloud computing" and so on. Of course, chaos is also a criterion for the prosperity of the industry. However, as a medical user, how to grasp the industry trend in this chaos and choose a product that is practical and applicable to the hospital's own application environment is an extremely realistic problem.

The technical route of hospital security development

At present, the security industry and the hospital's application environment is a typical multigenerational industry. The analog monitoring system born in the 1980s is represented by audio and video matrix, and still has some applications in hospitals; later modular monitoring The system is represented by video encoders and still occupies half of the hospital security. The new generation of digital surveillance systems, represented by network cameras and management platforms, have made great strides.

If the hospital security system five years ago was still in the age of simulation, the newly established medical security system has already been digitized and has evolved towards the intelligent stage.

Each technical route has its own advantages and disadvantages. Although the analog monitoring system has a long history, it is simple in construction, low in غير مجاز مي باشدt, and easy to operate, and can also meet the needs of small and simple monitoring systems. However, as the country’s investment in health care systems has been increasing year by year and affected by the imbalance of medical resources, the size of hospitals in major cities has rapidly increased, which has led to the rapid expansion of the scale of hospital security systems. The monitoring system goes beyond the management capabilities of the matrix. Digital surveillance system on the one hand solves the problem of management capabilities. On the other hand, management platform software greatly expands the application capabilities and industry characteristics of the surveillance system. On the other hand, digital surveillance systems have many advantages, but their openness still needs to be improved. Therefore, the choice of new technologies should be more cautious. Among the many new technologies in the security industry, we have selected several representative technologies for analysis.

HD

In the entire video industry, HD has always been a hot technology in recent years. At present, many provincial and municipal medical construction standards clearly require the use of high-definition systems.

HD implementation mode, Digital HD Camera (HD-SDI): A digital HD camera based on the HD-SDI protocol proposed by the HDCCTV Alliance. The main features are clear images, no delay, and transmission over the BNC interface. The application mode is similar to the traditional mode of combination of modules. It consists of an HD-SDI camera, an HD-SDI optical transceiver, an HD-SDI matrix, an HD-SDI encoder, or a DVR. Meet the high-definition monitoring while meeting the original application habits. However, the display and storage of the two systems need to be built separately, and the openness and expansion capabilities are relatively poor. The transmission link overhead is extremely high and the transmission distance is short.

Network high-definition video camera (IPC): Based on the HDTV standard, video encoding and network packaging are used to achieve high-definition real-time image monitoring at 720P, 1080I, and 1080P levels. The main features are the use of standard protocols, transmission via IP interfaces, simple deployment and implementation, unified management and easy expansion, and low construction غير مجاز مي باشدts. The mainstream manufacturers all adopt IP high-definition cameras as the main development direction. From the point of view of hospital security application characteristics, preference is given to centralized management and linkage applications. Optional integrated and more feature rich IP network cameras.

The establishment of high-definition systems: Security monitoring is an inevitable trend to the road to high-definition, but it involves the entire system, not only the front-end camera to high-definition, transmission equipment, storage devices, decoding devices, display devices need to be high-definition. Any link that does not meet HD requirements will form a system bottleneck, which will degrade the overall quality of the system.

networking

The basic requirement of network monitoring is information sharing and centralized management. At present, this is the bottleneck of hospital security construction. The construction of the hospital information system is synchronized with the construction of the national informatization system. From the 1980s to the beginning of this century, the main task of the informatization system construction was the construction of the information highway, with digital and network construction as the key points. Therefore, when the highway construction is completed and resources need to be shared, it is found that the multi-phase video surveillance system cannot be managed uniformly. The need for networking and unified management came into being.

Networking is not simply connecting multiple systems through a network. Instead, it establishes a unified management platform and implements resource sharing based on standard protocols. Therefore, the focus of networking applications lies in standards. At present, mainstream security companies are all promoting the standardization of the security industry. The more mainstream domestic standards are ONVIF and national standard GB/T28181.

ONVIF (Open Network Video Interface Forum): An international open network video product standard network interface development forum jointly established by Axis, Bosch and Sony, named ONVIF (Open Network Video Interface Forum). In November 2008, the forum formally released the first edition of the ONVIF specification. The latest version is ONVIF2.2. The ONVIF standard mainly defines the connection interface between the front-end network camera and the back-end management platform and the storage device. More than 80% of the IP surveillance products in the world have achieved the support of the ONVIF standard.

Technical requirements for security, video surveillance, networked system information transmission, exchange, and control (GB/T28181): Leaded by the Ministry of Commerce, TC100, and industry leading manufacturers participate in the development of national standards. It defines two standards for management platform cascading and interconnection. Released at the end of 2011 and has been promoted. It is mainly required that different video surveillance management platforms be networked based on a unified standard. Meet the actual needs of domestic hospitals for monitoring and networking.

Hospitals gradually embark on the road to safety and security

In the past 10 years, the focus of hospital security construction has shifted to building industrial applications on advanced basic platforms. At present, the construction of security monitoring systems is often a simple stacking of security subsystems such as perimeter protection systems, main/passive alarm systems, access control systems, intercom systems, video surveillance systems, and intelligent image analysis systems. The original manual analysis associates security incidents/emergencies reported by the security system with the on-site pictures of the monitoring system. The monitoring personnel have high labor intensity and low work efficiency. In modern wisdom hospitals, an excellent security system, although composed of several relatively independent subsystems, should never be a simple superposition between subsystems, but should be integrated under the unified framework of the security system. Integration, interaction, and become an integral part of the whole. Such a security management system integrated management platform is a large security platform.

The first stage of the construction of the Daan security platform is management. In multiple subsystems such as monitoring, access control, alarm, and patrol, the alarm and patrol system usually has a common output interface, which can be integrated through the switch network management system; the monitoring system is large in scale, but if a platform-level SDK can be provided, It is not difficult to develop; however, the access control system was mainly used in the early stage and has a very high level of confidentiality. Usually, it does not open the interface to the public and only provides query services. Therefore, it has become a major difficulty in security integration. This is why many security platform vendors are access control hardware vendors. The next stage of the construction of the Daan security platform is linkage. Flexible allocation of system resources to achieve mutual coordination and early detection of site problems to avoid accidents. Linkage is not just about technology, but more importantly management.

High-end technology, integration first

In the medical industry, the rapid innovation of security technology not only includes hotspots such as high-definition, networking, and large security platforms, but also rapid adoption of smart, integrated, NVR, panoramic surveillance, intelligent retrieval, cloud computing, and the Internet of Things. The application of various new technologies can improve the ease of use, scalability, and reliability of security systems. There are no absolute advantages or disadvantages for various technologies. The core point is to meet the basic requirements for the construction of security systems: advance prevention, emergency in the event, and playback afterwards.

Security protection system (SPS) securityotectionsystem is an intrusion alarm system, video security monitoring system, and entrance/exit control system composed of security protection products and other related products for the purpose of maintaining public safety; or they may be a combination of subsystems or Integrated electronic system or network.

There you have anything cheaper, underwear, of course. Women in order to make their body more perfect but also pay more attention to health, in the selection of underwear is a natural quality, but the price is "rising" and rising. Perhaps because of high prices, many women are reluctant to discard it.

However, women's bodies are subject to change from time to time, especially the chest, which can easily change with changes in physiology and changes in body weight. Once the body weight is reduced, the bust is the most shrinking place. In addition, with the body aging, bought underwear a few years ago may not be suitable for the body now, barely wearing only to the body cause discomfort or even pain.

The average life span of a bra is only one year

Allegedly, the average life expectancy of the bra only use about 100 times. If the bra for three days for a change, then bra life is only one year. As the bra often embroidered with beautiful patterns, the price is quite expensive, reluctant to throw the majority of women, so do not throw, you have to do a check on the performance of the bra.

Check the bra two keywords: "iron ring" and "shoulder strap"

An important option for choosing a bra is the iron ring inside the bra. If the iron ring can be placed just below the chest, it will not only support a tall and straight chest but also will not cause any tightening or uncomfortable feeling to women. However, after the permanent bra, the cleaning process is also easy to distort the iron ring, long-term wear such a bra will only hurt the chest. You can do a simple bra check as follows:
1, find a flat place to spread the bra well;
2, the perspective adjusted to the main view instead of the top view, observe the bra iron ring is attached to the plane, whether there is part of the tilt away from the plane;
3, if the brassiere part of the ferrule tilt away from the plane, then the iron circle has been distorted, this bra should be discarded, to buy a new bra.
In addition, if the shoulder strap no matter how short will still be loose, but also a sign of aging bra, poor quality.

Beauty Island underwear

Check the underwear keyword: "rubber band stretching"

Underwear if long-term consumption, but also to the female body will cause harm. Check whether the most important change underwear is to observe the elasticity of rubber bands, rubber bands have lost flexibility? In addition, the edge of each panty line head out? If you find that loss of scalability, or underwear looks bleaching, take the thread, then underwear has been replaced.

How to choose a reliable and durable access control intercom system has become a problem that many users are concerned about. Next, we will introduce the issues that need attention in the purchase of access control intercom.

Access control intercom to buy five to one, strong and durable

Rugged and durable can be said to be the most important condition of the access control intercom system. First, functionally speaking, what the door intercom system does is to protect the user's life and property safety. If it is not even strong enough, then why? Talk about protecting others? Secondly, the access control intercom system is a necessary place for users to enter and exit. It is used very frequently and therefore users can often hear complaints about the failure of the access control intercom system.

So how do you determine if a product is strong and durable?

It is recommended that users should consider the products of mature brands that are in the leading position in the world as far as possible. On the one hand, they have typical users and their quality has also undergone many tests, and they have been highly recognized in the industry.

In terms of hardware, devices from the controller to the terminal are mature and stable products. As the core of the system, the access controller needs to support the offline mode of operation. It must use flash and other non-volatile memory chips, and the power loss or impact information will not be lost. The failure of the server and terminal to identify equipment does not affect the normal operation of the system. In the case of a lot of man-made destruction, when selecting equipment, it should also pay attention to the performance of the product in preventing man-made damage, such as whether it has tamper alarms and similar functions.

Second, compatibility

Users all know that now a large-scale residential unit is not only a kind of, may be combined with multi-storey, small high-rise, high-level residential buildings of different grades, due to audio and video encoding and decoding algorithms, wiring standards, communication protocols, interfaces are not uniform and The resulting compatibility/standardization issues have plagued buyers. At this time, the multi-system compatibility of the device is required, so that different system requirements are integrated according to different levels of the community, so as to adapt to different user needs.

Therefore, in order to facilitate future upgrades, capacity expansion, and anti-jamming considerations, it is recommended that terminal identification devices comply with international standards be selected, and that the wider and better the compatibility, the better. Some formats have some advantages in terms of locality, but they do not conform to international standards. They will cause problems for future upgrades, capacity expansion, and anti-jamming. They should adhere to the principles of practicality, stability, and compliance with standards.

Third, anti-jamming design

Anti-jamming capability is currently a headache for the building intercom industry. In terms of product quality, anti-jamming capability is urgently needed, especially in some areas where thunderstorms occur frequently. In the field construction, improper selection of wires and irregular wiring may also cause various interference problems. Therefore, it needs to cause widespread concern for product suppliers and construction parties.

At present, the rated voltage of most building intercom door power supplies on the market is 220V, the AC peak or composite voltage is 190-250V, and the test voltage of the anti-electric strength should be 1.5kV. To meet this requirement, it can only meet the requirements of sudden changes in the circuit system, but it cannot resist the lightning overvoltage and excessive current. Therefore, building intercom doors should have lightning protection and grounding devices with good anti-static, anti-lightning, and leak-proof designs, which can avoid many problems in the later use of products.

Fourth, human design

Access control intercom products are products for the general public, and humanization is one of the most important features.

The humanized design here mainly refers to the humanization of the user interface, including indoor units, door machines, etc. For the purchaser, it is often used by children and the elderly. Therefore, the operating mode and interface should be as foolproof as possible. , For example: language prompts, family mesغير مجاز مي باشدes, etc. during the operation; screen graphic interface is more abundant, not just text prompts.

As for this point, users should learn more about the products they purchase, and after they shop around, they can choose the products they like and fit.

Fifth, powerful software management functions

With the increasingly wide range of applications for access control systems, it is required to implement linkage control functions with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, and online patrol. Therefore, the system software should have video Interfaces and support for extended functionality.

In addition to the above points, there are some keywords like easy maintenance and anti-crash design that users should pay attention to when choosing a door intercom system. It is better to choose a mature brand product so that while ensuring product quality, , but also to ensure the perfect and powerful service system, will save a lot of trouble later.

Access control intercom purchase eight points to see

In addition to the above five key points, we also need to know the following eight points to purchase a high-performance access control intercom system.

One, strong stability

"Stable" is the first choice for the selection of access control systems. It should consider the mature products that are in the leading position in the world as far as possible, pass a number of authoritative certifications, and have many typical users. It has been operating for many years and has been highly recognized in the industry.

In terms of hardware, devices from the controller to the terminal are mature and stable products. As the core of the system, the access controller needs to support the offline mode of operation. It must use flash and other non-volatile memory chips, and the power loss or impact information will not be lost. Failure of the server and terminal to identify equipment does not affect the normal operation of the system. As the management software supported by the system, it should have a stable and reasonable database structure design. Between the hardware and the real-time polling method, the communication connection and address of the hardware should be maintained and monitored. Complete data integrity, reliability, consistency.

Second, extremely strong anti-destructive ability

Access control systems are used to protect people and property, so the system itself must be safe. The high security mentioned here refers to the natural or quasi-natural properties of the product or system. It should ensure the safety of the equipment and system operation and the safety of the operator. For example, the equipment and the system must be able to withstand high temperatures and low temperatures. Hot and humid, and can prevent static electricity, anti-jamming, etc.; on the other hand, access control and security systems should also have anti-human damage features, such as: with tamper alarm.

Third, excellent compatibility

To facilitate future upgrades, capacity expansion, and anti-jamming considerations, it is recommended that terminal identification devices comply with international standards be selected, and that the wider and better the compatibility, the better. Some formats have some advantages in terms of locality, but they do not conform to international standards. They will cause problems for future upgrades, capacity expansion, and anti-jamming. They should adhere to the principle of “practicality, stability, and compliance with standards”.

Fourth, flexible scalability and economy

It is suggested that the number of registered card rights need to reach 30,000, which can be suitable for the vast majority of customers' requirements for storage capacity, facilitating attendance statistics and expanding the scale of the company. The main equipments should adopt modular design and adopt advanced wiring methods. Through software and hardware upgrades, future system expansions can be achieved without having to make major changes to the system, maximizing the economical principle, and at the same time, products should be غير مجاز مي باشدt-effective.

Fifth, powerful software management functions

With the increasingly wide range of applications for access control systems, it is required to implement linkage control functions with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, and online patrol. Therefore, the system software should have video Interfaces and support for extended functionality.

Six, easy to maintain

The system should be easy to install and configure, simple and popular, and have a unified network management capabilities, easy to maintain.

VII. Purchase of mature brand products at designated agents

Mature brands can guarantee a perfect and powerful service system. This includes two aspects: First, technical support and thoughtful after-sales service for the project; second, reliable follow-up research and development capabilities to ensure continuity and compatibility of new and old products.

Buying from agents can have reliable quality and perfect services. Buying from other channels may have lower prices, but technical support and after-sales service may not be enough.

Eight, product appearance

With the improvement of people's aesthetic standards, while pursuing function and practicality, one can use its design as one of the reference standards in order to realize additional functions of visual enjoyment.

Common Rail Tools

Common rail tools are specially for common rail injection system repair, it covers disassembly and assembly tools, measuring device, adaptors for different injectors, grinding machine, cleaning machine etc.

These tools meet different maintenance applications, are easy to use, and greatly improve maintenance efficiency.

Since 2014, the concept of VR has begun to attract widespread attention worldwide. Internet industry giants have also begun to enter the field to test water, trying to occupy a place in the early stage of the industry development. In China, BAT entered the market in 2016. At the same time, more than 60 listed companies have declared cross-border VR industry, and the hot market outlook is promising. Some people even called 2016 as the first year of the VR industry.

However, in the second half of 2016, the VR technology that was originally associated with the turmoil of the future, quite a bit of "future technology, the general trend," suddenly fell rapidly and ushered in a sudden industry reshuffle, just as all emerging industries developed. The VR industry will not be easy, and it will eventually become a "wound" that almost all manufacturers can't say. Many well-known big companies and more than 200 previously announced VR projects were quickly Stop and freeze storage.
Almost in the same period as the cold wave of the VR industry, many VR companies such as Storm Mirror, Mido Entertainment and Zhongjing Vision have incurred arrears and layoffs, and cast a shadow over the prospect of the VR industry. However, at this stage, there are still more people in the industry who believe that this round of cold waves may not be the overall picture of the industry, but that the overall situation is in an adjustment period and the market will gradually return to rationality.
In fact, this view of positive energy still does not save the VR industry's market attention. The time has come to the first half of 2017. The VR industry that has been rapidly cooled does not seem to have "adjusted" its completion, with a new one. The gesture appeared in front of the public. This once-hot market has shifted from the tepid to the cold, which is quite embarrassing.
The earliest appearance of the VR concept that began in the 60s with more than 50 years of development began in 1935. The novelist Stanley.Weinbaum described in the novel a VR glasses based on glasses, including vision, sense of smell, touch, etc. The immersive orientation of the virtual reality concept, the novel is considered to be the world's first to propose the concept of virtual reality.
After the concept was introduced in 1935, until 1962, a virtual prototype machine named Sensorama was developed by Morton Heilig to be simulated flight training in virtual reality. The VR technology at this stage was limited to the research phase and did not produce products that could be delivered to users.
· I don’t say you may not know that Nintendo was the first of the first game game companies to enter the VR industry to enter the VR market and launch products. Since 1994, Japanese game companies Sega and Nintendo have launched separate games for the gaming industry. Products such as SegaVR-1 and Virtual Boy really caused a stir in the industry at the time. However, due to the high غير مجاز مي باشدt of equipment, the actual experience of the game is very limited. In the end, this game machine product ended in a market failure.
Therefore, the VR industry did not appear until 2014. It was only after Facebook acquired Oculus for 2 billion US dollars this year that it successfully brought the industry to market. Only then did the VR boom sweep the world. With the international technology giants beginning to deploy VR industry in 2014, companies represented by HTC, Facebook, etc. have all launched finished products, and have continued to gain popularity in the following more than one year. In fact, after the Internet giant deployed VR, it further stimulated the intervention of capital. It can be said that the capital holds the VR industry. However, the enthusiasm of capital companies does not represent the maturity of VR technology.
Dizziness + Cable-bound VR technology is not yet mature We all know that to get the best experience, we must use VR devices to deceive our eyes and create a sense of distance before and after the display, but we want Knowing that the screens of display devices are generally planar, to display a multi-dimensional space on a plane object, it is not simply a matter of large and small distances that can be controlled, including changes in light, changes in shadows, etc. Among the factors, it includes "deep depth".
In electronic display devices, the most direct rules of sketching are the two concepts of “focus” and “depth of field”. These two concepts are separated from each other. However, the virtual environment generates an image with binocular parallax, but it has a significant depth and blur feeling. The place the eye wants to observe is imaginary, which itself is uncomfortable.
Summary: The construction of a three-dimensional space on a screen with a planar structure requires the aid of depth-of-field effects. However, this traditional model of assisted construction is inconsistent with our binocular vision. Reality and virtual parallax have caused us to adapt. Caused dizziness.
In addition to vertigo, even more unbearable is the VR products can not get rid of the current wire constraints, when the 2016 VR technology broke out, in fact, the author did not show much enthusiasm for it, due to its reasons, or because the technology is not Mature, can not get rid of the shackles of the wire, in a sense with the theory of VR wearable devices products again contrary to the theory.
Summary: If VR products can not achieve wireless display, then can not be called mature technology, and to achieve wireless display, one is to break the wireless display data transmission problems, which takes time, two will Let glasses have their own computing power, and this requires more غير مجاز مي باشدts, but also means a higher price, the best example is the Microsoft Hololens price up to 20,000 yuan.
Success or Failure is "Xiao Ho" Capital is the double-edged sword in the VR industry to get the capital to chase the entire industry, the crisis is also quietly coming in the second half of 2016, this is the first embodiment of the VR company's arrears, layoffs and bankruptcy. In October 2016, once one of your benchmarking companies in the field of VR content, Mido Entertainment, was exposed by the media to wage rumors, saying Mido Entertainment’s employees and retired employees were owed pay for as long as a half month to 4 months, and the last thing The solution is not very gentle.
The reason is because the high غير مجاز مي باشدt of the technology itself and the smaller user base make the risk of investment content production high, which in turn restricts the enthusiasm of content production and is caught in a vicious cycle. Short boards for domestic VR content production may still need to wait until cheaper hardware and simpler applications come out before they can be truly resolved.
The intervention of the capital market has made the immature VR technology enter the market quickly. It is quite a bit of a momentum to “get the ducks on the shelves.” After the technical defects are known, the huge investment of capital cannot break through the bottleneck of technology. At that time, the market will return to rationality and the strength of capital will become smaller. This will lead to the lag in product development and the “very cold” of the company’s R&D plan. .
It is true that when the top PC VR platform's image quality and vertigo have begun to be criticized, manufacturers and users are aware that the performance of current VR products is still far from enough. The difference between the VR one-in-one and the VR glasses is exactly the degree of fifty steps and one hundred steps, which is not enough to fundamentally solve the flaw of the user experience.
Since it is only bought to taste fresh, then about 100 yuan VR glasses is enough, VR one machine prices are generally in four digits, expensive even four or five thousand dollars, willing to serve as a mouse user is not enough to support this There is no established industry-standard emerging market. After all, if you can't guarantee high-quality follow-up content, the fresh energy will soon pass. High-end mobile phones may be a luxury, but expensive VR all-in-one machines have become a waste.
To sum up, the ultimate profit-oriented industry leads to prosperity in the industry. It is always mature technology and excellent products. Under the background of consumer upgrading, consumers are willing to pay for a better sense of experience, provided that this product is Value for money.

Peppers are rich in vitamins E and C, and they also contain capsaicin, which is only found in chili peppers. In red and yellow peppers and sweet peppers, there is also capsanthin. Both of these ingredients are only present. In pepper, capsaicin is present in the pepper flesh, and capsanthin is found in the pepper skin. Its role is similar to that of carotene and has a good antioxidant effect. Therefore, people who like to eat peeled chili may not eat chili Red pigment.

In addition to heat and pain, chili peppers are also used as slimming aids because of their ability to promote the secretion of adrenaline and increase metabolism. Capsaicin also has the effect of reducing platelet visغير مجاز مي باشدity, and therefore it has also become a health care for maintaining cardiovascular health. Food is a hot ingredient, but because it's highly irritating, gastrointestinal or heart pain, chest tightness people recommend avoiding food.

When the pepper's spicy taste stimulates the nerve endings of the tongue and mouth, the brain immediately commands the whole body to “guard”: the heart rate is accelerated, the secretion of saliva or sweat increases, the stomach doubles “work”, and endorphins are released simultaneously. If you take one more bite, the brain will think that there is a bitter experience and release more endorphins. The continuous release of endorphins will make people feel relaxed and excited, resulting in a "pleasantness" after eating spicy food. Another factor in eating chili addiction is the effect of capsaicin. When the sensory sensory cells are exposed to capsaicin, they are more sensitive and feel the deliciousness of the food.

When people eat chili, as long as they do not hurt the mouth, the taste is rather sensitive. In addition, when eating chili, the secretion of saliva and gastric juice in the oral cavity is increased, the gastrointestinal motility is accelerated, and when people do not eat at a fragrant place and their appetite decreases, they have the idea of ​​eating chili peppers. In fact, regardless of spicy addiction or not, the right amount of chili to eat has a certain therapeutic effect on the human body.

First, stomach, help digestion.

As mentioned earlier, pepper has a stimulating effect on the oral cavity and gastrointestinal tract. It can enhance gastrointestinal motility, promote secretion of digestive juice, improve appetite, and inhibit abnormal fermentation in the intestine. Some medical and nutrition experts in China surveyed provinces such as Hunan and Sichuan and found that the incidence of gastric ulcers in these provinces and regions that commonly eat chili peppers is much lower than in other provinces. This is because the pepper can stimulate the release of human prostaglandin E2, is conducive to the promotion of gastric muغير مجاز مي باشدal regeneration, maintain gastrointestinal cell function, prevent gastric ulcers.

Second, prevent gallstones

Eating green peppers can prevent gallstones. Green pepper is rich in vitamins, especially vitamin C, can be replaced by excess cholesterol in the body into bile acids, thereby preventing gallstones, those who have gallstones eat more vitamin C-rich green peppers, to alleviate the disease has a certain effect.

Red apple red peppers prevent breast cancer - The researchers found that red apple and red pepper and other "red skin" fruits and vegetables have a preventive effect on breast cancer and other cancer diseases.

Third, improve heart function.

Pepper is used as the main raw material, together with the extracts of garlic, hawthorn and vitamin E to form a “health care product”. After eating, it can improve heart function and promote blood circulation. In addition, regular consumption of pepper can reduce blood lipids, reduce thrombosis, have a preventive effect on cardiovascular disease.

Fourth, lower blood sugar.

Scientists in Jamaica have demonstrated through experiments that capsaicin can significantly lower blood sugar levels.

Fifth, relieve skin pain.

Studies have found that capsaicin can relieve skin pain caused by many diseases. In fact, there is indeed a medicinal pepper cream, but it is not used to lose weight, but used to - stop pain! Surprisingly, capsaicin can hurt people's pain. It was originally stimulated by capsaicin to allow the substance P, which is essential for the development of pain, to be released. Therefore, in the process of recombination and accumulation of substance P, people are less sensitive to pain and play an analgesic role.

Six, pepper has a weight loss effect.

Pepper contains a component that can stimulate the body's heat system by dilating blood vessels, effectively burning body fat, speeding up metabolism, and speeding up the body's caloric consumption, thereby achieving weight loss.

Colorless, odorless capsaicin can give a burning sensation to mammals because it stimulates receptors on the nerve receptor called TRPV1 and releases a substance P that is closely related to pain perception. Substance P has a function of dilating blood vessels and accelerating blood flow, so the site stimulated by capsaicin will become red and heat. This reaction is similar to the body's fever after exercise. It may lead people to mistakenly believe that they can play the same role as exercise. As everyone knows, the real reason for exercise to lose weight is the consumption of a lot of energy, and fever is only accompanied by the phenomenon.

Some studies have pointed out that capsaicin may have a weight-reducing effect, but instead of using chili cream directly, it is taken directly [5]. However, to be finally confirmed as effective, and as a safe drug for weight loss, further research is needed, and through the strict safety effectiveness approval of drug regulatory authorities.

Seventh, prevention of cold

Spicy foods have the "three links" that are good for the lungs, accessibility, and smoothness of blood.

Eight, radiation resistance

Red pepper, black pepper, curry and other spices can protect cell's DNA from radiation damage, especially gamma rays.

Nine, help longevity

Chinese medicine believes that spicy foods can not only promote blood circulation, but also increase the activity of brain cells, helping to delay aging and relieve various diseases.

Ten, warm stomach cold.

"Food Herbs," said that pepper can warm the stomach. If you have symptoms such as vomiting, diarrhea, and stomachache in the cold, you can eat some peppers properly.

Eleven, promote blood circulation.

Pepper has a certain medicinal properties, so it can "in addition to the wind and sweat, phlegm, dehumidification." Interpretation with modern medicine is to promote blood circulation, improve cold, frostbite, vascular headache.

Twelve, skin beauty.

Pepper can promote hormone secretion and improve skin condition.

Thirteen, lipid-lowering diet.

With the further development of high-definition, not only has the front-end video capture equipment changed, but the high-definition video data traffic has soared. This has also placed higher demands on the back-end storage management equipment. Some people say that the development of high-definition will inevitably prompt NVR to replace DVR. However, the emergence of HD-SDI cameras has brought new opportunities and challenges in the field of video storage devices. HD-SDI hard disk recorders are stored in such high-definition storage. Demand came into being.

The monitoring system based on SDI-DVR as a management device has outstanding advantages. First of all, compatibility with other devices currently on the platform is good. SDI cameras can only directly access SDI-DVRs through coaxial cables. Video data is not like NVRs. After compression and multiple conversions, the picture quality is better compared to the traditional DVR.

H.264 shows off its talent again

As we all know, the digital signal output by the SDI camera is very large. If it is not encoded, the back-end storage is almost impossible. From the A&S "Safety Automation" test SDI DVR found that manufacturers have adopted a more extensive and advanced H.264 compression format, H.264 can maintain a high compression ratio, but also have a high quality and smooth Video images are also the main compression algorithms used in the surveillance field. From the test situation, the video stream has been effectively controlled. Under the 1080P@30fps standard, the stream detected by the SDI-DVR monitor is generally 4-6mbps. This encoding compression process also makes SDI. The high storage requirements of the video stream data of the camera are no longer a problem in its promotion and application. After solving the problem of data storage, how about the loss of SDI video signal after decompression? This is also the key performance of SDI-DVR. From the test results, we can see that different manufacturers have different brands. The SDI-DVR's picture quality loss is also very different. Select the same HD-SDI camera as the video signal input source. Compared with the test, in terms of definition, some SDI-DVRs can still reach 1000 lines after decompression. There are also some obvious sharpness attenuation, in the reduction of color, the same situation, the use of different DVR hardware, as well as the internal design process and other details, all make different SDI-DVR performance difference. However, it is certain that most of the SDI-DVR compression and decoding results are better than the output of an IP camera with 1080P@30fps set by the same parameters. In addition, in terms of delay performance, although HD - After the decompression and conversion of SDI, the data transmission has a certain delay, but after testing, the delay time is generally much smaller than the delay time of the IP camera itself, which is exactly the greatest advantage reflected by the SDI monitoring system.

Streaming media technology to coordinate bandwidth

In the design of the video playback function, this test can also see that many manufacturers attach importance to transmission bandwidth control. After the SDI-DVR compresses the SDI digital signal, when the user performs a monitoring operation through a remote IE login client, it also causes network bandwidth problems. Streaming media technology is designed to alleviate this problem. Streaming media technology can also be referred to as streaming media technology. The principle of this technology is to store the video and audio information in a compressed server and store it on the server. The user can download while watching, instead of waiting for the entire compressed file to be downloaded to his computer. Can watch the network transmission technology. In general, in networked monitoring systems, it is often necessary to adopt streaming media technologies to implement distributed network monitoring applications and to avoid network bottlenecks caused by concurrent traffic. However, you can see in the actual test, click to view the playback video, while detecting the size of its stream, under the influence of streaming media technology, the video file is automatically downloaded to the local while playing, resulting in the playback stream compared to the time of entry The code stream is much larger. If several channels of video are also being monitored in real time, the bandwidth will still have a certain impact. Manufacturers should provide setting options, such as setting different download speeds according to the bandwidth environment of different users, so as to ensure that the bandwidth occupied during playback can be viewed without affecting surveillance video or real-time monitoring of other channels.

Stability is still the main appeal

This time SDI-DVR uses Linux as the operating system. In fact, Linux has always been the mainstream operating system used by DVRs. SDI-DVR is also applied in this system architecture. The stability advantages of embedded SDI-DVRs come from not only The low failure rate of the hardware depends largely on the high stability of the operating system and application software used in the embedded DVR. The software platform chosen plays a crucial role. In this test, SDI-DVRs can generally access 2-8 hard disks or more, and have e-SATA interfaces to expand capacity at any time. In terms of exterior structure design, in addition to being beautiful and sturdy, there is a requirement that heat dissipation must be good. The more SDI-DVR video compression cards, the greater power consumption, heat dissipation, plus the hard heat source, excessive heat accumulated in the chassis, will cause system instability. The products tested this time, the inside of the chassis will usually be designed with 1-3 small fans, to strengthen the heat dissipation inside the chassis and increase the air convection.

In terms of video output resolution, the biggest advantage of SDI-DVR can be said to support HDMI high-definition output. Because the security industry as a whole is moving toward high-definition, SDI-DVR's high-definition output can compete with NVR even higher. In terms of latency, SDI-DVR must also be superior. The SDI-DVRs tested all have at least one HDMI output interface, and most of the manufacturers' products can output TV, VGA format video synchronously, and there are also DVRs with mixed analog-digital design. The video output format selection is more flexible and diverse. .

future development
It can be foreseen that due to the advantages of HD-SDI camera images and real-time video data transmission, the next few years will inevitably become a product sought after by manufacturers and engineering firms, and the equipment they support will also receive attention. The importance of end-to-end management storage SDI-DVR is self-evident, I think the future SDI-DVR can go further in the following aspects.

1, screen clarity

Sharpness has always been a key indicator for customers' choice of products, and image quality is a core issue in evaluating digital video recorder product quality. With the development of high-definition technology and the popularity of high-definition cameras, high-definition DVR will be the target for the development of the next generation of DVR manufacturers.

2, a more efficient compression algorithm

In order to meet the needs of high-definition storage, improve image storage time, and reduce the bandwidth used during transmission, vendors are developing more efficient compression algorithms. Currently, the commonly used compression algorithm is simplified H.264.

3, centralized storage

With advances in digital technology, the amount of data to store more and more, to meet the high storage requirement is an important issue DVR manufacturers need to face. The video surveillance system is from data acquisition, transmission, storage to digital data collection, transmission, storage, from the original space to the current remote monitoring, remote storage, remote recovery technology applications, with the improvement of the system, is also experiencing A step-by-step evolution and refinement will integrate technologies such as NAS, SAN and ISCSI in the future, and the data will be stored directly on the network. This is an inevitable trend in the development of storage technology.

4, the operation interface

Improving the software operating interface and increasing the added value of software profits is a direction that every DVR manufacturer expects to change. From the appearance, interface, operating habits and other details start, change China's image of manufacturing, make the interface closer to the user's use. The application of the graphical interface and the clarity of the colors will bring new sensations to people, and they will be the basic indicators for customers to choose their products.

5, smart technology

Intelligent technology enables the video surveillance system to allow the identification and processing that originally required the on-duty personnel to intervene to be completed by the computer, thereby greatly reducing the workload of the on-duty personnel and improving the security quality. With the advancement of projects such as "Safe City", massive video information makes SDI-DVR solve the storage problem on the one hand, and on the other hand it must provide strong support for remote or local search.

Introduction: The State Council issued a document a few days ago and proposed to further expand and upgrade information consumption and benefit the general public. It is expected that the scale of information consumption will reach 6 trillion yuan by 2020. How to promote the high-end upgrading of intelligent information products and lead the consumer upgrade has become the focus of attention in the industry. On August 29th, the Sohu-DTS-Xiaomi three-party alliance, the heavy launch of the TV DTS area of ​​Yuet Hotel made its debut and launched an exclusive line of Xiaomi TV. Industry insiders said that the tripartite cross-border cooperation and the new eغير مجاز مي باشدystem of home appliances with hardware+content+internet built will use the ultimate experience in sound and lead the consumer's consumption upgrade needs.

Do not forget the early days, Yuet TVDTS area aimed at consumption upgrade Blue Ocean

Currently, a new generation of smart hardware is accelerating change. In the State Department’s document on further expanding and upgrading information consumption, it is clarified that it is necessary to combine the development trend of the industry and focus on promoting the application and promotion of digital home products and applied electronic products. In terms of digital home products, it is proposed to encourage enterprises to develop smart home “product + service” models for customized application scenarios.

“In the near future, I believe that movies will eventually become Internet-based. Not only in the form of content production and distribution, but in terms of play and experience, it will be completely Internet-based.” Wang Quanfeng, general manager of Sohu’s video home entertainment division, believes that The new generation of audio-visual carriers represented by Internet TV is rapidly updating and iterating, and consumers’ demand for home audio and video entertainment will also be “highly increased”.

Today, consumption escalation is happening everywhere in life. From the CBNData "Report" also pointed out that "post-90s" and young female consumers are the leaders in home scene consumption. According to statistics, the number of households in China has reached 500 million households and the population of 20-29 years old has exceeded 228 million people. The endogenous potential of the huge consumer population base has brought tremendous imagination space to the “living room economy”.

Needless to say, content quality and user experience are key factors in the success of home entertainment products. Based on the above concepts and trend judgments, to meet consumer demand for upgrades, China's earliest Internet video company Sohu, global audio technology leader DTS, Xiaomi Technology Inc. launched Sohu Video Studio TV DTS area on the same day, and exclusively launched Xiaomi TV.

"The three companies will integrate the advantages of technology, content, and platform, and provide Hollywood movies with 5.1 surround sound audio technology and 1080p HD picture quality to users free of charge, so that consumers can enjoy a cinematic audio-visual experience at home without leaving home. At the product launch and fan meeting held on the same day, Sohu Video, DTS, and Xiaomi TV's tripartite leaders jointly initiated the initial cooperation.

Technology first, creating unfettered audio and video experience

Voice is the existence of "invisible" in life. But good sound effects can make people forget about themselves and concentrate more on content. When it comes to the origins of DTS and the film industry, many people think of director Steven Spielberg and the Jurassic Park that made DTS famous overnight. Since then, DTS has laid a decisive position in the film industry as well as mainstream Hollywood studios.

As early as 1996, DTS won the highest award in the American film industry Oscar - Best Film Technology Award. Currently, there are more than 2 billion devices equipped with DTS technology worldwide. Involved in product areas including AV amplifiers, computers, mobile devices, car audio, Blu-ray machines, television, cinemas and so on. 93% of the nation’s best-selling Blu-ray discs use the DTS format as the main audio track. "From the perspective of the Chinese movie market, eight of the top ten films at the box office as of August 21 this year adopt the DTS:X format. Currently, "War Wolf 2", which has become a box office myth, is currently being released. Both of them have adopted the DTS:X version, "said Dr. Zhang Xiaoming, vice president of eغير مجاز مي باشدystem services at DTS China. With such a deep technical foundation, DTS will cooperate with Sohu and Xiaomi in depth and will provide viewers with high-quality multi-channel movie content and a better surround sound and video experience.

Speaking of technology leadership, Wang Chuan, head of Xiaomi TV, added, "It's not an exaggeration to say that Xiaomi TV 4 is a high-end product that can change the living room into a cinema in the second." From the hardware point of view, every millet TV supports DTS. Audio decoding, which captured the Oscar in the design sector - the 2017 Red Dot Award for the Millet TV 4 also has a heavy upgrade. The full range of DTS-HD audio decoding is supported, and the sound is extremely shocking.

The content is king, Internet TV audio and video service has great prospects

The ultimate ecological experience is an important part of the “living room economy”, and good content is the core of the entire ecology. The scarcity of high-quality content resources is precisely one of the pain points that limit consumption escalation.

In response, Wang Quanfeng stated that in addition to maintaining a 90% coverage rate for domestic hit TV dramas, Sohu Video also made frequent efforts in web-based comedy, net animation, variety shows, and American dramas.

“The broadcasts of several boutique home-made dramas such as Assassins' Biography 2′′, Unwitting Master 2′′, “Hypnotized Hypnotist”, and “Drawing Heart” have continued to increase, stimulating the growth of advertising, membership, and payment platforms. On the frontline variety and on-line production of US dramas, overseas content, etc., Sohu Video continues to maintain its leading position in the first platform of the US drama.” Wang Quanfeng believes that Sohu, as one of the earliest Internet video companies in China, will be committed to providing high-quality to users. Video service.

"Roughly calculated, if a person watches a movie every day from the first day of birth, it will take 74 years to watch all the movies on Xiaomi's TV." Wang Chuan, head of Xiaomi TV, said that as an exclusive terminal on the TV DTS area of ​​Yuet Office. The huge amount of content resources such as Hollywood blockbusters, cinema movies, hot variety shows, and head TV shows is one of the most important reasons for fans of Xiaomi TV. This is also due to the powerful combination of content giants such as Sohu.com. It does not matter.

Wang Chuan, head of Xiaomi TV, also stressed that the three parties’ in-depth cooperation will open up a continuous supply of high-quality audio and video content for consumers, leading the consumer update to a new chapter.

According to an agency survey and forecast, the penetration rate of smart TVs has increased from 19% to 86% in the short period of three years from 2012 to 2015. By 2020, the overall scale of the “living room economy” will reach trillions of yuan, and there will be good market prospects. The rapid growth rate is pushing the entire industry to accelerate the integration of technology and product innovation.

According to the analysis, the in-depth cooperation between Sohu, DTS, and Xiaomi, and the construction of a new home entertainment eغير مجاز مي باشدystem based on hardware + content + the Internet, will become a new benchmark for cross-border cooperation and mutual benefit.
