Aloe identification

Shape identification

(1) Amethyst rhizomes are irregularly nodular or slightly beaded cylindrical, and some are curved, usually one branch, 3-10 cm long and 1-2 cm in diameter. The surface is yellow-brown to gray-brown, with fine longitudinals, wrinkles, and a few residual fibrous roots. There are often shallow transverse grooves in the joints. There are round scars between the nodes, often with residual stems at one end and occasional scars. Some precipitate white flocculent crystals on the surface. Solid quality, easy to break, cross-section is slightly uneven, white or yellow-white, scattered most orange or brown red oil room (commonly known as cinnabar point), exposure is slightly longer, white fine needle-like crystals can be precipitated. The cross-section was not blue fluorescent under ultraviolet light (254 nm). Rich in aroma, slightly sweet and bitter and pungent.

(2) Rhizoma Atractylodis rhizome is mostly lumpy, some are nodular, often curved and short-branched, 4-10cm long and 0.7-4cm in diameter. The surface is dark brown and has an outer oil chamber that does not give off crystals after being placed. The aroma is weak and bitter.

(3) The roots of Atractylodes lancea are mostly nodular cylindrical, 4-12cm long, 1-2.5cm in diameter, and dark brown on the surface. Lighter weight, broken section fiber. Gas-specific color, spicy and bitter.

It is better to have a solid quality, more cadmium spots, and a strong scent.

Microscopic identification

Atractylodes rhizome cross section:

1 There are 10 to 40 layers of cork cells in the cork layer. There are between 1 and several stone cells in between, and each stone cell has about 2-3 layers of rectangular stone cells integrated.

2 The cortex is broad, with large oil chambers scattered between them, with a long diameter of 225 to 450 μm. The phloem is narrow.

3 form a layer into a ring.

4 There are fiber bundles on the inside of the xylem, which are aligned with the catheter group. The 5 rays are wide, and there are oil chambers in both the ray and the pith.

The parenchyma cells contain inulin and fine calcium oxalate crystals.

Cross-section of rhizome of Atractylodes lancea: There are fiber bundles in the cortex, and the fiber bundles in the xylem are relatively large, and they are aligned with the catheters.

Atractylodes powder: brown.

1 Stone cells are single or in groups. They are round, oblong or polygonal in shape, light yellow or yellow, and are 20-80 μm long. The walls are extremely thick, woody, with prominent pits or pores, and are often associated with cork cells.

2 Fibrous spindles, often bundled, with narrow cells, some with blunt ends and large cavities.

3 The catheter section is short, the main is a net pattern, and there are bordered pits.

4 Calcium oxalate has small needles, 5-30 μm in length, and irregularly stuffs in parenchyma cells.

5 Oil room debris more common.

6 Inulin crystallizes into a fan or block, with a radial texture on the surface.

(3) Thin-layer chromatography Atractylodes lanceolata, Atractylodes lancea, and Atractylodes lancea powder each 50-100g, and the essential oil was extracted with a volatile oil extractor. Aspirate a certain amount of volatiles and dilute with ethyl acetate to a 10% deep liquid as a deep liquid for the test. Separately, a mixed solution of Atractylone, Atractylodin, Maofu alcohol, and Sterol was used as a reference deep liquid. Take the deep liquid and reference solution for the sample, and point it on the same silica gel G (Qingdao) thin plate. It was developed with benzene-ethyl acetate-hexane (15:15:70) with a 20 cm spread. Remove and dry it. The spray was developed with 10% sulfuric acid deep solution containing 5% p-dimethylaminobenzazem: after spraying, it was baked at 100°C for 5 minutes. The chromatogram of the test product was in the corresponding position with the reference substance, showing the spots of the same color. After the coloring agent was sprayed, Atractylone immediately showed a red color and was purple after baking; Atractylodin, Maoshu alcohol, and Emu oil were not developed after the coloring agent was sprayed. The oleyl alcohol is brown. [3]

One: On the issue of linkage We often encounter the problem of customer interaction: Commonly there are on-site linkage lights (equipped with a big horn next to the detector, a searchlight next to the detector, there is an associated linkage immediately when illegal invasion), linkage Monitoring (After the alarm, the camera corresponding to the defense zone immediately turns to the alarm position, and the corresponding monitoring screen immediately after the alarm pops up on the monitor, maximizing the display of the alarm area screen), associating some barriers (control of the entrance and exit gates of the parking lot vehicles), and linkage count (product line count) and so on.

For these linkages, we will expand from two aspects:

The first kind of linkage method is also our most common, directly through the relay joints of dry joints, we call it: hard linkage;

For hard linkage, we have two methods for the need for on-site linkage of lights, on-site linkage video, and various linkages in the engine room category.

The first type, which is the simplest and most direct, directly connects the alarm signal to the dome camera alarm access point or the light access point (usually the normally open access) through the relay at the detector end. This method is simple, convenient and direct. However, there is also a problem: the linkage of this alarm, because there is no alarm host, so the host can not control the opening and closing of the linkage. In other words, even if the host disarms, if the person triggers an alarm, it will also perform linkage.

Another way of hard linkage is to use a variety of relay modules (Bosch DSR-32C) on the control panel. The alarm switch signal output by the relay module is directly connected with the alarm signal access terminal of the DVR/matrix one by one. This is more convenient, but if this method requires the linkage of the equipment at the front of the site, it will be very unreasonable to pull more cables from the relay to the site.

Of course, for the above two methods, some manufacturers have now introduced a zone module with a field relay output on the bus. The emergence of this module is a good complement to the two shortcomings of hard linkage. It can not only realize the on-site linkage light, but also the linkage of the relay module can be turned on and off by the host computer room.

The second kind of linkage method is common through the software-level linkage of TCP/IP, 485, and other protocols. We call it: soft linkage.

Soft linkage is generally applicable to modern large-scale centralized management platform software. Often an integrated software platform can manage alarms, monitoring, building intercom, entrances and exits, and all weak systems. This generally requires us to provide corresponding interfaces. Protocols and SDK Development Kits. The commonly used protocol is the TCP/IP protocol, which explains to some extent the current trend of security—networking.

Two: On the issue of long-distance transmission On the issue of alarm signal transmission, conventional close-range (within 2400 meters), we generally use ordinary wire to connect. The family uses the wireless transmission, the small factory uses the common sheath line RVV2*1.0 to carry on the line switch quantity transmission, the medium type warning project generally uses the shield line RVVP2*1.0 to carry on the 485 main line transmission.

For long-distance transmission, how do we generally solve it?

The first kind is to use optical transceivers to transmit alarm signals through optical fibers. The commonly used optical transceivers have a half-duplex bidirectional 485 data optical transceiver. Second: It is applicable to larger systems, such as all bank outlets in China, all judicial departments, and centralized management of some chain stores. We generally use the internal private network, LAN, and WAN for centralized management and control.

Three: Regarding the Networking Operation Market Before we talk about network operation, let us give the simplest example: We are most familiar with telecommunications, mobile and China Unicom. What do they use to make money? Network, of course, can also be said to be a channel. With the Internet, with channels, you can earn calls and network fees at regular intervals to make profits.

It is also influenced by this idea that the alarm industry has also slowly transformed from the original single point (a company, a factory, a store) model to today's networked operations.

We know that the initial networking alarms were basically the responsibility of local bureaus and security service companies. With the promulgation of the Regulations on the Management of Security Services, private enterprises that now meet the conditions are slowly becoming involved in the networked alarm field, and the networked alarms are also increasing in size. There are generally the following modes of operation:

First: lease type: pre-equipment is provided free of charge. According to the nature of the user, the scope of protection will be charged monthly.

Second: billing type: pre-equipment needs to be purchased and used, according to the actual number of police charges.

Currently, networked operations have become increasingly sophisticated. Coupled with insurance companies’ insurance policies, operators are basically free from any risks. In the earlier period, channel outlets were rolled out, and monthly fees were charged on a monthly basis. There was no security situation and there was no need to worry about the situation. Only regular equipment maintenance was needed. An insurance company was responsible for the payment of stolen losses.

In China, video surveillance accounts for half of the security market, but in foreign countries, networked alarms are the highlights, so the future development of the burglar alarm market depends to a large extent on the development of the network alarm operation market!

In today's society, piracy, robbery, and fraud prevail. As the saying goes, it's absolutely necessary to guard against human beings. Teach you 9 strokes to make anti-theft robberies, and everything will be fearless since then.

First anti-theft meter

No matter whether it is a bus, a food market, or a crowded street, there are always some people who are not good-natured, eye-catching to the purses and mobile phones that people carry around. To deal with these "third hand," you should use advanced defense techniques.

The first count of the iron wall against the burglary is only to confront the "iron wall." At present, the tactics of ordinary burglaries are mainly using violence and technical unlocking. In order to improve anti-theft capabilities, tenants should reinforce the doors and windows. Ordinary wooden doors basically do not protect, and the general aluminum alloy window is also very easy to be dismantled, should use hard material, anti-theft effect of better materials to strengthen the doors and windows, doors and windows are locked when you go out, do not readily close things .

The second eye-catching sight is located in a crowded place where people can avoid the threat of a third hand. The crowded crowds have become their best cover because of their high flow of people and their complicated shopping malls, food markets, stations, and buses. In these places, the citizens should improve their vigilance, carefully observe the surrounding people and situations, and once they find anomalies, they can immediately take countermeasures to ensure that the safety of their own property is not compromised.

The third plan is to stop and choose the location of the vehicle to determine its "fate", remember to think twice before stopping. According to police survey data, most vehicle theft cases occur because the owner parks the vehicle at random on the unguarded roadside. The general theft is from 11 pm to 5 am the next day. If you want to stop overnight, you must choose the parking lot to be guarded. Don't put your car in the parking lot to save more than ten dollars. The danger of burglary. At the same time, the police reminded that the vehicle is not a safe. Do not put cash, handbags and other valuables in the conspicuous place in the car.

The second set of anti-fraud meter

If you say that the "third hand" steals valuables in a visible way, then the fraudsters behind the scams that are woven into sweet talk are unknowingly stepping out of your pockets. Since ancient times, there have been thousands of methods for fraud, but the model of “giving first sugar and letting you save money” has always been inseparable.

The fourth plan met with prior doubts whether face-to-face, saying "send gifts" or "buy the reason", or send text mesغير مجاز مي باشدes, call "winning", "kid kidnapped," "family accident," and the first step of the liar must be first. Contact with the deceived person on the basis of an excuse, and then the implementation of the entire scam is based on the swindler's belief in this excuse. Therefore, if you want to not be cheated, encounter sudden sudden good things or sudden bad things, you should first make a few question marks in your heart and make your own decisions.

It's not a good thing that the fifth euphemism guards themselves to break the casserole. It is not a good thing, especially for the links attached to strange information.

"Do you have a look at this album? Do you have an impression?" "This is a photo of us hanging out together. Let's take a quick look." With the advancement of technology, the methods of communication fraud have continued to revamp. For this type of unfamiliar number or even a friend's number, which is accompanied by a web link, the citizens must manage their own fingers and do not click with curiosity. Otherwise, a small movement on your finger can make your money drain.

The information of the sixth plan, such as account number and password, is closely related to the safety of its own property. The relationship between words and phrases should be tight-lipped and should not be disclosed.

With the popularization of smart phones and networks, many people nowadays have a mobile phone. In a small cell phone, there are not only the account passwords of various communication tools, but also the account passwords of Internet banking. For such information, we must pay attention to protecting privacy and do not reveal it to strangers at random so as to prevent them from being stolen by malicious people. Even good friends are better not to disclose, so as not to cause unnecessary disputes.

The third set of anti-robbery

Compared with theft and fraud, robbery and robbery are more violent and more harmful, but it is not difficult to prevent. To improve their own vigilance and do a good job of security, naturally do not give robberies an opportunity.

If the seventh financial plan is not exposed, it must not be listed as a target for criminals. Most of the targets of robbery such as sprinting by rovers are exposed property. When the citizens took to the streets, they should pay attention not to install large amounts of cash or to wear gold and silver jewellery in the vehicle lane. Cyclists pay attention not to place valuables in their pockets or baskets.

In the eighth assessment, the time and place matters are very important. The handling of property matters should pay attention to assessing the situation. Although the prevention of robbery should pay attention to financial disclosure, but when visiting ATMs, money exposure is inevitable, so we must pay special attention to access to the time and place. The police reminded that when choosing to deposit or withdraw money, it should try to avoid choosing ATMs located in remote streets and alleys. If there are no other machines in the vicinity, they should avoid time points such as early mornings and evenings to prevent them from being spotted by criminals.

The ninth plan alone is not a night when the lawbreakers love to leave the night out, compared to the daytime, people who go out at night are more likely to become snatch targets. Therefore, the general public, especially women, should try to avoid walking alone at night and pay attention to safety.

Video surveillance platform software development status of

video surveillance industry has gone through twenty years of development, today has a more complete and well-developed industry. With the development of video codec technology, from the analog era to the digital era, after experiencing the turbulence of H.263, MPEG4, and H.264 technologies, we finally ushered in the era of H.265, despite the current popularity. H.264. In this process, the video surveillance platform software has always played an indispensable role and played a major role. While promoting its own development, it also directly or indirectly promotes the codec technology, transmission technology, load balancing technology, and application technology. The promotion also satisfies the needs of a wide audience for monitoring shared functions.

Currently, in the context of very close integration of information technology and applications, the role of video surveillance platform software generally has two roles: one is the convergence of video and equipment management, the other is the sharing of resources and data applications. In the early development of the surveillance field, the first role dominated. This is an era of fortification and also a closed-loop era. Each video surveillance company has built its own market barriers by attacking cities in a low-competition, large-expansion climate. At this stage, most video surveillance manufacturers want to play their own characteristics and build their own domain on the original video codec and packaging technology. And the considerations for sharing (such as the harmonization of standards) are second only to that.

After experiencing such a "happy era of the Warring States Period," we ushered in an "empire age." In this era, I am afraid that most of the traditional video surveillance manufacturers are not so happy. First of all, the vast majority of people, to be exact, the majority of Internet users have progressed. In that happy era, video surveillance users were mostly “outsiders” who did not know how to operate and did not understand domain appeals and characteristics. Among them, there are old grandfathers who are all trembling with the mouse. There are also gimmicks who have just entered the field and who use video surveillance as a display platform or supporting role. Their requirements for monitoring the platform may only be able to look at the video and project it on the TV wall.

However, technology is advancing, and the industry is developing. After experiencing a period of unfathomable "unexplained" years, vast numbers of users quickly become familiar with monitoring software, thus creating a large number of "domain experts." They have a higher level of requirements for monitoring software, the video is not clear, how much bandwidth the transmission takes, the resolution, how long the storage, and so on, and the demand is more and more intense. On the other hand, each manufacturer can not dominate the world to occupy all areas of the market, in different areas, different market areas will have the requirements of resource sharing and interoperability, but also the development of software customization requirements. Especially in cities and provinces where Safe City is more developed, this requirement is very urgent. Whether it is possible to share video with heterogeneous systems of other manufacturers or whether it can be used to customize the development of some unique features of the units and fields has become an inevitable issue in this era.

ZNV ZTE strength video surveillance platform software development status

ZNV ZTE has been making video surveillance software one of its pillar products since its establishment in 1995. After experiencing the functional stage of video aggregation and device management, it has also embarked on the road to customizing domain requirements and sharing with other manufacturers' heterogeneous system resources.

However, ZNV's customer base has always been relatively broad. In addition to meeting the needs of operators and towers, *, transportation, electricity, education, railways, radio and television and other industries have involved. Of course, these industries are different in positioning and understanding of the video surveillance software platform, and the selection and use of software functions are also different. Some users use video surveillance as their main business, for example, the * field, map detection has become one of the four major detection methods, and due to the confidentiality mechanism within the industry, the sharing needs will be low, and further, others give Resources can, resources are harder for others. Some industry users regard the domain application as the main business, and video surveillance is only the auxiliary business. Other users, such as operators, are more inclined to exchange transmissions. They do not produce video. They are just video porters. In addition, for example, radio and television users, their requirements for video is to converge and share, providing channel set-top box channel material.

For many years, ZNV ZTE has been working on integration and has strong integration capabilities. As a result, ZNV's business forms are more diverse, meeting the functional needs, experience needs, and purchasing needs of different customer groups. Of course, as the onvif protocol is widely recognized in the field of domestic video surveillance and popularization of various national standards, integrated monitoring platform software like ZNV ZTE can offload some of the access pressure, but there are still a large number of non-standard monitoring. Devices and storage devices need to be accessed. For example, cloud storage devices, CMR devices, NVR devices, and even monitoring software platforms. Each of these hardware and software has its own characteristics. After being integrated, the users all hope to use the greatest value of each subsystem after integration. Due to the different functions, configurations, and uغير مجاز مي باشدe methods of hardware and software products of various manufacturers, the complexity of integrated software customization will inevitably be caused.

In addition, as a standard in the field of industry, national standards are the most authoritative and are an entry threshold. The significance of its formulation is to allow users and constructors in the video surveillance or field to realize resources at the minimum غير مجاز مي باشدt. Sharing and interworking eliminate ambiguity between semantics to the greatest extent possible.

Customized software market development and key issues

course customized software to meet the needs of most users for the field, but also caused some problems. From the developer's point of view, the coupling between software is too large, the stability and compatibility are poor, and the demand cannot be converged. From the user's point of view, problems such as inconsistent style, unstable and unsatisfied use of software, and gaps in expectations and implementation have always existed.

However, for the personalized needs of a large number of users and fields, software customization is inevitable and imperative. The emergence of a large number of customized video surveillance platform software on the market is proof. For example, in the * industry, the management of criminal investigation cases is not the same in all units, and the understanding of each software development company is also contending. In order to meet the convenience of the various units, they have to be customized and developed. If the model of the development model is not well designed, there may well be an awkward situation with a version of the code. There are also some issues that need to be resolved:

1. Stability issues Since customized software often adds a number of heterogeneous subsystems, cross-linking between systems requires coordination. However, the product levels of various manufacturers are uneven, and after being integrated, their stability is greatly reduced. For example, the SDK's access method is to integrate the third-party vendor's development package, so that the third-party modules run directly in their own process. Once the SDK has an illegal problem, it may cause the SDK's calling process to be illegal.

2. Maintenance issues The customization of software development and maintenance is a problem that has existed from beginning to end. The greater the degree of custom development, the greater the غير مجاز مي باشدt of maintenance and the higher the غير مجاز مي باشدt. At the same time, satisfying the business needs of different users requires developers to have a deeper knowledge of related fields, which, to a certain extent, also raises the threshold for the development of customized software and غير مجاز مي باشدts. It is hard to imagine that people who are not familiar with the field can develop excellent applications that meet the needs of the field.

3. Convergence of Requirements Customized software development is often a process in which demand and development go hand in hand. At the initial stage of software development, neither the user nor the acquirer of the demand often has the means to refine the requirements to the minimum granularity. This poses an obvious problem: the software developed does not match the needs of the user, or even differs greatly, resulting in the inability to converge. This is too common in custom software.

4. Software Security Issues This is not a problem with custom software but a problem with all software. The security of software mainly includes two aspects, network security and system security. In layman's terms, it is how to "defend the enemy outside the country" and how to "home-based combat." The surveillance equipment of a province's hall that appeared some time ago was invaded and controlled. In fact, it belongs to the first case. The manufacturer's coping strategy is mainly to strengthen the login password strength, etc. This approach is very thin for high-intensity intrusions.

Should the need to change, to seize the high ground

current market development, customized software in the field of popular video surveillance software for various industries growing, who wants to abandon the lofty software customized but outdated. The pursuit of software's productization blindly, trying to meet the needs of the product to meet the difficult audience, how much powerless. Customization software has such problems, but it is impossible to abandon it eagerly, not only can not abandon but there is still a growing reliance on the momentum, now buy a set of video surveillance platform software, if you do not add a little customization of the buyer's own desires are not going .

So how can video surveillance platform software manufacturers find a balance between productization and customization? How can we increase the gold content of customized security software, especially management platform software? How can we no longer be vulnerable to problems and غير مجاز مي باشدts? In addition to the traditional management of demand management, iterative development and other management methods, I think the following points need to be complied with and explored:

1. Output diversity of video and session protocols:

In the field of video encoding and decoding, most of them currently comply with the MPEG4 standard, using the compression method of H.264, and H.265 is also in the ascendant. However, the packaging of video streams from various manufacturers is all-embracing. Some manufacturers are privately packaged, some are RTP packages, some are PS (program stream) packages, and some are TS (Transport Stream) packages. What's more, the compression method has also changed, which has caused great obstacles to the decoder and the sharing. At the same time, various fields have different regulations for the encapsulation of video streams. For example, in the field of *, due to the introduction of standards such as GB28181, the PS stream becomes the output standard; in the field of broadcasting and television, the set-top box generally requires the input TS stream to be decoded normally. There are also some industry standards, such as the railway industry, where the encapsulation of video streams is more flexible, RTP can be used, and RTP can be extended. The video stream compression method is not limited to H.264.

In order to adapt to the demands of video streaming in various fields, an excellent video surveillance platform software should be able to cope with this situation, at least not embarrassing. Then we require that we can output a variety of session specifications and video streams, including SIP-based (GB28181, GB28059, DB41, etc.), http-based, rtsp-based, RTMP-based, SNMP-based, Based on a customized specification and the like, the video stream needs to be compatible with PS streams and TS streams, as well as various packaged video streams. The diversity of the output of video and conversation protocols is achieved. When dealing with resource sharing demands, the غير مجاز مي باشدt of customized development will be reduced to a minimum.

2. The video surveillance platform software and big data video monitoring software interfaced with so many devices and system resources. There are a large amount of data inflows and outflows at every moment. In addition to video streams, monitoring point alarm information, operation and maintenance data, and heterogeneous The domain knowledge of the platform formed a large-scale data group army. How to collect these data, each has its own tricks, but how to save and use these data is a new topic in the field of traditional security.

The popular Hadoop framework and data warehouse provide a good engine for us to complete the work. The data is stored in the data warehouse and is used for deep mining and forecasting through the Hadoop system. It combines algorithms and models in the field of artificial intelligence, such as Bayesian classification, clustering, rough sets, and sequence patterns, to learn a lot of knowledge and use machines. The learning algorithm can establish certain mining rules so as to recursively improve mining rules and improve the accuracy and quality of mining. The large amount of such a large amount of data is undoubtedly a new functional growth driver for customized monitoring software, providing ample room for the expansion of custom software features.

3. Video surveillance platform software and Internet The traditional video surveillance system is basically running on a private network, that is, running in a local area network. The outflow and inflow of video data form a relatively closed loop. However, in today's resource sharing, apart from sending our own resources to other systems, we must allow the general public to enjoy the dividends of safe city construction in recent years. The most convenient way is to use the Internet.

In the Internet industry today, Youku, Tencent, Potato and other large-scale Internet video sites are rare for the integration of monitoring resources. Most of their resources are entertainment. When we drive a long way, how to avoid blocking and choosing the best route becomes the most warm service for the owner. It is easiest to complete these operations through the mobile phone or PC browser. Can this service be reflected in Youku or Tencent's video service menu? In addition to being embodied, how can we strengthen rich and varied interactions and increase the diversity of choices? This kind of benevolent person sees the needs of intellectuals and wise men, and I am afraid that only software platforms with deep customization and multiple session protocol output can be completed.

4. Video Surveillance Platform Software and Security Software As mentioned above, the security of software is not a problem unique to customized software but is a problem faced by all software products. In particular, how can customized video surveillance platform software enhance network security and system security? I think the following strategies can be taken:

Network security: Traditional vendors generally adopt strategies such as adding firewalls, secure access gateways, and strengthening login authentication when dealing with network security. In addition, the method of adding filtering drivers can be used to deal with network security problems. Network traffic can be monitored and diverted in the network protocol stack driver. The TCPIP driver serves as the provider of the TDI (Transport Driver Interface) service, and the upper layer is the AFD (Auxiliary Function Driver), among which is TDI. Above AFD is the user-space socket library. You can add more drivers in the user space (ie, AFD), and you can add filter drivers in the TCPIP driver.


System security: System security mainly refers to system intrusion and anti-intrusion, virus detection and so on. It can generally be detected and dealt with by rootkit technology. For example, hooking system call descriptor table (SSDT), interrupt descriptor table (IDT), IPR processing function table, IAT (Import Address Table) of a specific process and other technologies. In addition, patching the calling process is a common practice. Through these means, the system functions or general procedure calls that are invoked can be effectively linked, registration of process calls can be realized, and combined with data analysis and machine learning methods, abnormal behavior and illegal processes in the system can be detected, which is in video surveillance. The field is also very meaningful.


Software customization future development trend
Software customization is in an important position in the development of the video surveillance management platform. It now exists and will exist for a long time to come. Its rise and fall are closely related to the development of various technologies in the monitoring industry and the advancement of monitoring methods. There are great opportunities and many problems. In the development of software customization, access and standardization, output flexibility and diversity can effectively reduce the غير مجاز مي باشدt of customization. In addition to traditional application programs, it is also possible to build a software protection system and a security registration system that integrates the operating system and application programs by taking over system services or adding filter-driven drivers, which is very effective for improving the security and robustness of customized software. significance. Of course, this also requires a higher technical threshold.

Talk about the use of AC and DC test transformer Note This morning, a customer calls to ask: "Test Transformer after the completion of AC withstand voltage test and then touch the test object with a grounding discharge rod, you can hear the sound of" 啪 "discharge. Why?” In the course of communicating with this customer, Ms. Li, the engineer learned that the other party's tester had done a DC voltage withstand test before inserting the shorting bar of the silicon stack and did not tighten it in place (ie, the silicon stack was not short After that, Xiao Li did not check the voltage withstand voltage (a few kilovolts) before conducting AC voltage withstand tests.

After stepping down and powering off, novice Xiaohan took care when he touched the test object with a grounded discharge wand, and he heard the sound of the discharge. Xiaoqing Li’s “overkill” and escaped. After being scared, Xiao Li called for telephone consultation. Engineers emphasized that: Before using a test transformer with DC output function (such as YD (JZ) or YDC (JZ) type) for AC withstand voltage test, be sure to confirm that the silicon stack is shorted by the shorting rod so as not to accidentally lift the DC high voltage. After the power was cut off, the electric shock caused by the ground discharge was not done.

If a sound is heard in the high voltage bushing during the boost test, it should be alerted. This is because the shorting rod is not screwed into place (ie, the silicon stack is not shorted). The test object is charged with a DC voltage and should be depressurized and de-energized. Afterwards, use the grounded discharge rod to fully release the charge that may remain on the capacitive test specimen to avoid electric shock accidents. The resistance of the multimeter can be measured in advance to measure the resistance between the high voltage head A and the high voltage tail X (generally several thousand ohms to tens of kiloohms, with no difference between forward and reverse directions). To confirm that the high voltage silicon stack is reliably shorted.

Want to buy electronic scales, if you choose to buy, experience is OK, if the user is only the first time to buy electronic scales, and electronic scales do not buy experience, how to buy a good electronic What about the scales? Don't worry, hard-working electronic scales Xiaobian has prepared this article for common questions and detailed answers to electronic scales. I hope to help everyone.

Purchase electronic scales common problems and detailed answers:

Question 1: What is an electronic scale?

A: The concept of electronic platform scales is very vague. Even the introduction of the encyclopedia is very few, and not too popular. Here, we think you should understand the concept of the more popular statement: First, it is a small commercial weighing scale; Is the use of electronic technology and scale body other manufacturing technology; the use of mechanical and electronic combination formed a scale body. The second is that in the entire electronic scale family, it is small; in small weighing scales, it is also large.

Question 2: What is the size of the electronic platform scale?

A: Smaller scales than electronic scales are table scales and electronic balances; electronic scales and truck scales are larger than electronic scales; of course, this refers to the size of the weighing range.

Question 3: What is the basic frame of electronic scales? What do you look like?

In order to let you more fully understand the size and basic structure of the electronic scale, you can see the following figure:

Question 4: What is the weighing range for electronic platform scales?

A: The weighing range of the electronic platform scale is between the table scale and the electronic floor scale. How do you say that? Its weighing range is between 30KG-1000KG, which is the standard default weighing range; however, it is recommended that heavy weight products use electronic floor scales as much as possible. Of course, if electronic scales are more convenient, it is still preferable to use electronic scales.

Question 5: There are not many types of electronic scales? How much can you choose?

A: It depends on which manufacturer to sell; this is critical. At present, there are not many well-known electronic weighing device manufacturers in China, so most manufacturers only sell one or two models; while the smaller ones even have only other scales; this scale does not; currently there are several functional electronic scales that can be provided in hard work. You need to also go to the home electronic scale area to purchase. In addition, we also provide Ding Ding’s total service for electronic platform scales. Only you can't think of it. We can't do it.

Question 6: (For the questions raised by hard electronic scales), are your products of high quality? Is there any guarantee after sale?

A: I believe that product quality is a problem that every user is very concerned about. High quality is not critical. It is a must for each user to purchase a product (any product). What I would like to say here is that quality is not a good thing. Our products have always been judged by our customers as quality products. Therefore, we can become a well-known domestic weighing instrument manufacturer today, and most of them are very user-experienced. OK, so volunteer to help us with word of mouth.
