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.

Dear Customer:

Thank you for your attention to our products. In addition to this product introduction, our company also introduces the vacuum tester, infrared thermometer, dielectric loss tester, high voltage test transformer, vacuum oil filter, high current generator, etc. If you are interested in our products, welcome to inquire. Thank you!

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. Many customers are introduced to each other, so the quality is good or bad, and it doesn't help. You know after you purchase.

Shanghai Electronic Bench Scale Service Commitment Guarantee:

Over the years, our company's continuous innovation and after-sales service have been continuously improved.

Wireless microwave transmission equipment is the use of microwave wireless transmission equipment, right? At present, the more common ones are about four types of mobile wireless transmission devices, digital wireless transmission devices, analog wireless transmission devices, and 3G/4G wireless transmission devices.

Did not say which kind is good, which kind is not good. Because they are all different types, they are not used, they have their own advantages and disadvantages, and they are better based on actual needs. You haven't explained the situation here. I can only give a brief introduction to each of them.

For example, mobile wireless transmission equipment is generally used in vehicles, ships, drones, individual soldiers, and so on. When the current camera is continuously moved to a location, it is necessary to use mobile wireless transmission equipment.

Digital wireless video transmission equipment, the corresponding equipment for digital cameras, network cameras and other situations, the transmission distance up to 100 kilometers, is currently the most commonly used wireless transmission equipment.

Analog wireless video transmission equipment, the corresponding equipment for the analog camera, DV, etc., the transmission distance is close, often used for short-range wireless transmission.

3G/4G wireless transmission equipment for emergency and temporary work such as emergency, rescue, and rescue.

Normally, these four types of equipment are available at Tengyuan Zhituo. Interested parties can go to Tengyuan Zhituo to find out.

With the gradual increase of vehicles in small and medium-sized cities, the “difficulties in parking” in first-tier cities have gradually shifted to small and medium-sized cities. The development of “Internet +” will also set off large waves in the parking industry. The direct fluctuation will be the parking fee system. So, what kind of form will the future parking lot charging system charge?

The traditional parking lot charging system is still in the form of cash and labor. Now it is slowly turning to the card-swapping mode. However, for those who are only temporary parking users, it is really not possible to use the card, and it is really for this purpose. Payment will gradually become mainstream.

Nowadays, the most authoritative online payments are Alipay and WeChat. What are the differences between online payment and cash payment in the parking fee system? First, online payment is more convenient than cash payment. The user only needs to open the online payment interface before leaving the parking lot and click on the payment. After the completion, the user can leave the parking lot without having to queue up for payment. Secondly, online payment is more convenient, the binding card can be used to pay directly, and there is no need to re-pay for monthly or annual cards. Once again, online payment is more favorable. Car owners can receive parking vouchers from time to time via online payment. Parking is cheaper.

And how to choose online payment, then with the user's favorite, Alipay started earlier, but also many people like a payment method, WeChat payment because of the binding of the chat function, it has become a public favorite payment method. But the two are different ways of cashing out, Alipay does not charge money to take the fee, and WeChat needs, specifically which one to use, to see the customer favorite and parking administrators to collect it.

Under the development of “Internet+,” traditional payment methods are unlikely to meet user needs, and online payment will gradually become the mainstream charging method. This is also an indispensable stage for the realization of “Internet + parking”, and Alipay WeChat payment will be the vanguard of the parking fee system.

If you have any problems with the parking system, please pay attention to Dreida or pay attention to the Drexel WeChat public number: szchinatenet. Welcome to consult and exchange.

OFweek smart home network news from BB machine to Big Brother to today's mobile phone, although its shape is constantly evolving, but from the overall trend of view, the homogenization of the appearance and high with low-غير مجاز مي باشدt promotional strategy has made smart phones quickly The popularity has also entered a period of slower pace. At the same time, the Internet of Things, smart homes, and artificial intelligence have become the new targets that technology giants are chasing in pursuit of in order to catch up with the next mobile Internet. Among these, you have to talk about artificial intelligence.

Speaking of artificial intelligence, you have to say smart speakers, which is the best way to present artificial intelligence.

In 2014, Amazon officially announced the launch of the first smart speaker, Echo, and the "concept" of artificial intelligence officially entered the user's home. Echo's role is equivalent to the home's "hub", any smart home products can be accessed through Echo's Alexa intelligent voice system control, this light-touch mouth-to-hand operation, did attract a vote of the courage to early adopters of the user.

Since then, Google and Microsoft have also released their own "built-in artificial intelligence" smart speakers Google Home and Invoke. After Apple introduced HomePod, a smart home product at wwdc this year, Apple officially entered the field of smart speakers.

Lynx Elf X1 box

These speakers are playing hot abroad, but quietly in the country? The reason is that Echo's built-in Alexa doesn't support Chinese operations first, and Google Home doesn't plan to enter China. Hopefully the largest HomePod will support Chinese, but the main music experience plus high selling prices may not be popular in a short time. To Chinese users' homes. In a short period of time, these foreign big coffees still have considerable resistance to enter the artificial intelligence field in China.

Although foreign companies are "unintentionally" but domestic companies are "emotional," Jingdong's Xenon speakers and Lenovo's smart speakers have opened the era of domestic artificial intelligence. Of course, how can Alibaba be lost in the field of smart speakers in China?

On July 5th, Ali's first self-developed artificial intelligence speaker, the Lynx X1, was released. How was this speaker an artificial intelligence?

Appearance: Visible Technology

Lynx Elf X1 Appearance

Like the current smart speakers, the Lynx X1 is a small cylinder with a diameter of 83 mm and can be easily held by one hand. The matte material attached to the body feels very good. The Sina Digital gets black, and there are white options.

In the middle of the cylinder Tmall's Logo is looming, and the lower circle is covered by a net cover, and the interior is where the entire speaker sounds.

The top has six radio microphones around the circle, and the middle is the mute button. This is the only button for the entire speaker. There are hidden volume keys on both sides of the mute button.

Lynx Genie X1 Appearance Bottom LED Strips

The bottom of the power link "hide" with a circle of LED lights, currently supports blue, white, red three color display. It should be noted that this speaker does not have a built-in battery and can only be powered through the power cord.

The black and low-key Logo of the Tmall Genie X1 makes it appear inconspicuous and unassuming at home. When the day cat Elf X1 is turned on, the bottom light strip brings a "future sense of technology" to this speaker.

This speaker is a bit different

Since it is a smart speaker, its system is critical. Tmall Elf X1's speech recognition technology is different from other smart speaker used by the University of science and technology, such as the voice recognition technology, go out to ask questions, but Ali's independent research and development of speech recognition - AliGenie, its advantage lies in the use of Voiceprint technology, which recognizes different users based on sound conditions, guarantees security and privacy of use.

Lynx Elf X1

Based on this voiceprint recognition technology, Ali also introduced the voiceprint purchase function, which is currently the first commercial voiceprint shopping system in China. To complete payment through voice print, when you initiate shopping, recharging, etc., you only need to speak the voiceprint password. The voice recognition system will check the identity and confirm that it is the person who will complete the transaction. Otherwise, the request will be rejected.

The contents of the speakers are from the Himalayan FM, and they also include shrimp music from Ali Eco. In addition, they also have a richer content library with fitness applications such as Keep.

The most important point of the Tmall Elf X1's voice can not only enjoy music, fitness, or memo reminder, it can also be associated with smart home products, is currently connected to Ali smart home platform, graffiti technology smart home platform, Gubei There are 56 categories such as the smart home platform, more than 1,000 smart hardware, and other smart home platforms will follow.

In addition to voice, Tmall Genie X1 uses MediaTek's first chip specifically developed for the intelligent voice industry, and has optimized and optimized decoding, noise reduction, sound processing, and multi-channel collaboration. For voice assistants, a large number of audio processing and sound synthesis work environments are required. The custom chip incorporates an independent NEON processing unit. The NEON technology can accelerate audio and voice processing, telephone and voice synthesis.

Experience: good voice quality, more accurate voice recognition

After opening the Lynx Genie X1, make associations according to the voice prompts. The voice prompts just after booting surprised me a lot. Its voice is more like talking to you. According to the official introduction of Lynx Genie X1, the voice actors in the speakers are selected from 100 voice actors and finally selected to be more in line with the vocals. Sound settings.

Record sound pattern after wireless link with speaker

Closer to home, the Tmall Genie X1 is paired with a mobile phone. It is very simple if you follow the steps in the software. Tmall Elf X1 and the mainstream smart speaker have the same two links, one is to join the WiFi, the other is an ordinary Bluetooth connection, of course, only the WiFi connection can have more intelligent voice operation, Bluetooth is only responsible for listening song.

After the WiFi connection, the speaker presents a white color, and after the Bluetooth connection, the display is blue, which is very good from the color point of view. After the association, this speaker can be used.

Let's talk about the actual application experience.

Thanks to the 6-way microphone, it responds very sensitively. You don't need a lot of sound to wake it up. The light band under the speakers matches the voice recognition and brings you some sort of agility.

Lynx Genie X1 Speech Recognition

It can be seen that the voice recognition of Tmall Genie X1 is very sensitive. Even if the wrong character is recognized, the correct content can be identified according to the context. In addition, user voice recognition and speaker dialogue content will be presented to the mobile phone App at the same time.

Since we are getting a test version, there may be some minor problems. For example, when I ask for the weather, I will show it to “Guangzhou” and I’m in Beijing. When I’m told to listen to radio instructions, the local station resources may not be There are many, but the Internet radio content such as comic dialogue is still very rich, when you do not want to listen, you can directly mute the microphone through the top of the mute.

Unfortunately, Tmall Elf X1 can control a feature of smart appliances that we did not test. I believe this is also a lack of most current Chinese families. Smart home is still in the stage of popularity in China, so the smart home direction may be the focus of the future but not the present.

In the end, speaking of voiceprint purchase, the official said, it can identify everyone's different voices and present thousands of people's preferences. We also use voiceprint purchases to perform mobile phone recharge operations, but due to the voiceprint purchase content also Not on the line, so it cannot be recharged successfully. However, it can be imagined that after the voiceprint purchase function is on line, it is more convenient to recharge the mobile phone.

A little suggestion:

In the process of using the Tmall Elf X1, sometimes the special information from the “Tmall Supermarket” was received, but the content of the promotion was somewhat inconsistent with me, and I hope that the future Tmall Elf X1 can identify through voiceprint recognition. , Push different promotion information.

There are also some minor issues that hope to improve. For example, its current understanding of English is not very good. This is a hard-hit area for users who like to listen to English songs, and it cannot blur speech. Users need to speak a complete speaker to recognize. For example, "I want to hear Mayday", the Tmall Elf X1 will reflect the "Mayday" song, not the Mayday band. Only "I want to listen to Mayday songs" will be recognized.

to sum up:

The biggest difference between smart speakers and ordinary speakers is that they can be used as a speaker and can be used as a link to link every smart product in the home. Although smart life still seems to be far away from us nowadays, from the speaker to the Tmall Genie X1, smart speakers are becoming more and more functional, and voice recognition is becoming more and more intelligent. I believe in the future In the era, speakers will become a must.
