For a long time, AT gearbox has been regarded as the shoulder of the gearbox industry, which is loved and touted by the majority of riders. It is fuel-efficient, resistant to operATion and can be trampled at will. As long as AT is mentioned, people will involuntarily think of these labels. However, from the actual maintenance ratio, AT is not as reliable and durable as the legend, and with the increase of service mileage and years, the failure rate of AT gearboxes is increasing day by day. The most important thing is that due to the high precision of AT gearboxes, the maintenance prices of 8AT and 9AT gearboxes are also expensive. So if someone tells you that the AT gearbox can be operated at will, you should give him a big face-scraper!

Why on earth? Please look down!

AT gearbox adopts planetary gear sets to change the transmission ratio, and the engine power is input to the input shaft through the hydraulic torque converter, and then the change is realized through the natural gear ratio of sun gear, and. Multiple clutches are designed in the gearbox to fix the planet carrier or ring gear of planetary gear sets to realize the output of different speed ratios. In addition, the combined speed ratio can be realized by fixing the planet carrier and ring gear of multiple planetary gear sets at the same time.

Usually, a set of planetary gears can achieve three different speed ratios, and six different speed ratios can be achieved through two sets of superposition. However, considering the actual speed output, not every speed ratio is usually effective.

AT gearbox and engine are usually buffered by hydraulic torque converter, and engine power is transmitted through. The hydraulic torque converter is actually a closed cavity filled with gearbox oil. The principle of power transmission is that the engine drives the pump wheel to rotate at a high speed, which drives the gearbox oil to flow at a high speed, and the gearbox oil drives the rotation, and finally drives the turbine to rotate synchronously. The output shaft of turbine is connected with the input shaft of AT to realize power transmission.

Because the transmission oil transmits power, the efficiency is relatively low. Therefore, in order to improve, it is considered that the hydraulic torque converter is internally designed with a lock-up clutch. After a stable start, when the speed reaches more than 10km/h, the lock-up clutch locks. Form. However, when starting, shifting and braking, the locking clutch inside the torque converter is separated, which can allow the speed difference to occur. Avoid engine stalling.

In order to protect the planetary gear set AT the back end of AT gearbox, the locking clutch of hydraulic torque converter is separated at the moment of gearbox upshift, and the multiple clutches in gearbox are quickly separated and combined at the moment of gearbox upshift, so as to realize different speed ratio output.

There are many parts of AT gearbox, usually reaching more than 400, especially for automatic gearboxes with multi-gears, such as 8AT, 9AT and 10AT. The size of parts is more compact and precise, especially for AT gearboxes with multi-gears, the shifting logic is very complicated and the valve body action is extremely complicated. There is a high requirement for the cleanliness of transmission oil. Therefore, AT gearbox needs to change gearbox oil regularly. Otherwise, the valve body may not open and close normally due to excessive impurities.

Many people think that AT is resistant to exercise, and can pedal with big feet and drive violently at will, which is quite wrong. The interior of AT gearbox is quite precise. When driving violently or even launching, although AT gearbox has a hydraulic torque converter for buffering, especially when shifting gears, the locking clutch can be released to form buffering, but the power transmitted by gearbox oil is also impactful. At the moment of shifting gears violently, the engine speed often rises rapidly, and the instantaneous impact force is relatively strong, which will certainly bring wear to multiple clutches used to lock planetary gear sets inside the gearbox. Therefore, the service life of the gearbox will be greatly reduced.

The key of automatic gearbox is to avoid shifting shock as much as possible.

• 1. When starting, don’t hurry to refuel. After shifting into D gear, wait until the power is turned on and the gearbox is full of energy, so as to avoid high-speed impact. Don’t play until the ejection starts.
• 2. Don’t drive violently with the big foot throttle when the car is cold, and the engine speed is too high, resulting in too much impact at the moment of shifting.
• 3. Try not to use the manual mode unless necessary, especially for the instantaneous downshift of the high gear. Although the shift can be protected instantly, the speed ratio of the gearbox changes too much in the manual mode and the impact is relatively strong.
• 4. Change the gearbox oil regularly, once every 60,000 yuan. It is recommended to change the gearbox oil by alternately combining the circulating machine and gravity, that is, after changing the oil in the circulating machine, replace the filter element at the same time at the next gravity oil change.

　　With the development of Internet and information technology, the Internet platform has become the main carrier for the whole society to obtain information, establish contacts, inherit civilization, entertain and relax, and the construction of network civilization is in the ascendant. In the process of network civilization construction and development, algorithm technology has brought great convenience to Internet users, but at the same time, its bias and abuse have also aroused people’s doubts, which has also become an important topic in network civilization construction. How to promote the comprehensive governance of algorithm technology through optimizing algorithm ethics and empower and help build an upward-oriented network civilization? On November 19th, the Convention on Self-discipline in the Application of Internet Information Service Algorithms, initiated by China Network Social Organization Federation at the first China Network Civilization Conference, provided a very useful exploration for solving this problem.

　　First, the algorithm and algorithm ethics

　　Algorithm refers to the accurate and complete description of the solution, and it is a series of clear instructions to solve the problem. Algorithm represents a systematic method to describe the strategic mechanism to solve the problem. At present, the deep development of Internet technology and artificial intelligence is promoting the wide application of algorithm technology. Technology is a "double-edged sword". While the algorithm is widely used, it brings a lot of convenience to the society, it also causes ethical problems of the algorithm, which brings new challenges to the current construction of Internet civilization.

　　Anderson proposed in Dependent Code: Advantages and Disadvantages of Algorithm Age that algorithms can really help us to process a large amount of data, which will bring many visible and invisible benefits, such as stimulating scientific breakthroughs, improving people’s creativity and self-expression ability, and creating new and convenient lifestyles. But at the same time, these benefits of the algorithm are accompanied by many challenges, such as too much pursuit of data and modeling, which will have various adverse consequences such as weakening human judgment, forming algorithm bias and deepening social differences.

　　Therefore, it is extremely important to regulate the use of algorithms from the perspective of algorithm ethics. Algorithm ethics is based on the unpredictability of algorithm consequences and the value load of the algorithm, with respect, safety, prevention, transparency and friendliness as its basic criteria, and with cultivating the moral imagination of the algorithm design subject and following the value sensitivity as its approach.

　　Second, face up to correcting the ethical anomie of algorithms and improve the civilized governance of cyberspace.

　　Network civilization refers to a new form of civilization with the application of information network technology, which has a very wide meaning, mainly including three levels: network technology civilization, network spiritual civilization and network system standardization civilization. The purpose of network civilization construction is to create a healthy, orderly, safe, dynamic and pollution-free "green" network environment. Algorithm is not only the core element of information technology development, but also the key topic of cyberspace governance. Its hidden social attribute has imperceptibly influenced people’s social life.

　　(A) algorithm ethics anomie infringes on network technology civilization

　　Algorithms bring convenience to users to a great extent, such as algorithm recommendation to help users filter information. However, some scholars believe that with the wide application of algorithm technology, the autonomy of the algorithm itself is enhanced, and the autonomy of the person as the subject is weakened, which shows a trend of trade-off, and even the subject is hidden. Autonomy, that is, self-management, is the ability of the subject to construct his own goals and values and to make decisions freely and put them into action. This is because the algorithm technology itself is designed as a decision-making system, which also leads to more and more dependence on algorithms in many fields, such as policy making, social services, medical health, media communication, etc., while users’ own rights and interests such as choice and informed rights are infringed.

　　(B) algorithm ethics anomie pollution network spiritual civilization

　　Because the algorithm design mode depends on the existing social mode and the designer’s social cognition to a great extent, the algorithm design is often the reappearance of the current social mode and the designer’s thinking, which often substitutes the inherent prejudice and discrimination of society and designers, thus causing algorithm discrimination. However, the existence of algorithm discrimination and prejudice not only damages users’ right to know, but also infringes on the legitimate rights and interests of some groups. In addition, the use of many technologies such as algorithm recommendation leads to the increase of the influence of personal prejudice and social discrimination in cyberspace, which leads to public opinion polarization, network violence and other problems, thus polluting the construction of network civilization.

　　(C) algorithm ethics anomie damage network system civilization

　　Schoenberg pointed out in "Delete: The Way to Choose Big Data" that "the Internet has enabled human beings to live in a digital circular prison". In this era of big data, "the past is like a tattoo on our digital skin, forgetting has become the exception, but memory has become the norm". While users are living digitally, data records also leave traces. When minors access the Internet and use social media and other applications, their personal information and privacy, such as their faces, names, location information and browsing records, are easily recorded and preserved by these applications, leaving traces of data that are difficult to clear. Even algorithm technology collects and uses users’ information without their knowledge, thus infringing on their personal information rights and privacy rights and other related personality rights.

　　Third, pay attention to the optimization of algorithm ethics, and build a network civilization that is upward and good.

　　The Convention on Self-discipline in the Application of Internet Information Service Algorithms puts forward new requirements for the technical subject of algorithms from the perspective of algorithm ethics and network civilization construction. Through summing up, it is mainly carried out around these three levels: first, using good technology to promote the construction of network technology civilization; Second, promote algorithm fairness and promote the construction of network spiritual civilization; Third, implement the responsibility of technical subject and promote the civilization construction of network system.

　　(A) the use of good governance technology to promote the construction of network technology civilization

　　Technical requirements such as "promoting innovation and development" are put forward in the self-discipline convention on the application of Internet information service algorithms. On the one hand, the algorithm governance mechanism is established technically, the algorithm governance organization is set up, the algorithm governance system is continuously improved, and the algorithm safety emergency management plan is established and improved; Implement algorithm governance measures, increase resource investment, carry out algorithm ethics review, carry out algorithm security risk monitoring, evaluation and prevention and control, and effectively handle algorithm security incidents. On the other hand, promote design R&D innovation, continue to carry out algorithm research and development, actively master key core technologies, and integrate into the overall pattern of global scientific and technological innovation; Governing the internet through algorithms. Promote the application and innovation of R&D algorithms in Internet and other related fields, and provide better services for national security, social progress and industry development. Promote the innovation of algorithm application, strengthen the application of algorithm in social and economic fields, and thus promote the construction of network technology civilization.

　　(B) to promote algorithm fairness, and promote the construction of network spiritual civilization.

　　The Convention on Self-discipline in the Application of Internet Information Service Algorithms proposes to "abide by business ethics" and "practice socialist core values". On the one hand, technical subjects should actively practice and maintain mainstream values, take socialist core values into the core consideration, and abide by social public order and good customs and business ethics. On the other hand, technical subjects should resolutely implement the requirements of guiding opinions, strengthen industry self-discipline, and consciously accept supervision and management; Promote the fairness of information recommendation, effectively deal with invalid and false information, avoid algorithm bias and algorithm application data deviation, improve the optimization goal of recommendation algorithm, and thus promote the construction of network spiritual civilization.

　　(C) the implementation of the main responsibility of technology, and promote the civilization of the network system.

　　The Convention on Self-discipline in the Application of Internet Information Service Algorithms emphasizes the institutional requirements of "implementing the main responsibility" and "strictly observing laws and regulations", and requires technical subjects to abide by the law from the aspects of information release, information review and personal data and privacy protection, thus promoting the civilized construction of the network system. First, it is to strengthen the consciousness of subject responsibility, fulfill the obligation of algorithm governance, and assume the responsibility of algorithm governance. Strictly abide by the relevant national policy documents and laws and regulations, strengthen the awareness of law-abiding and compliance, continue to study laws and regulations, carry out algorithm applications according to laws and regulations, and resolutely do not touch the legal red line, so as to promote the civilized construction of the network system.

Speaking of which, this brand was a fire in the past, and it was the best in the school. But now, domestic electric cars are becoming more and more luxurious, and the interior is getting more and more upscale. Tesla’s simple style really makes people feel a little guilty. Is it worth buying? Today, as an ordinary car owner, I will talk to you about the shortcomings that people love and hate. Of course, in the end, I will also talk about its advantages. After all, every product has its two sides.

Let’s talk about maneuverability first. Because the car body is high and heavy, it is replaced with a harder spring, and the chassis is also adjusted to be sporty. In this way, the handling and body support really have nothing to say, and it is called a cool driving. However, the suspension is as hard as a stone. When driving everyday, when the accelerator is lifted, the nodding and turning caused by kinetic energy recovery is simply unbearable. Especially when crossing the bumpy road, the comfort of the rear passengers is simply a big problem, just like riding a roller coaster.

Let’s talk about voice technology. Tesla’s speech recognition, how to say it, is a bit "straight". Its instructions are mechanical, not as humanized and intelligent as domestic brand electric vehicles. Although it has improved after the update in the last two years, it still lags behind domestic brands. There is also a map of the car. I have encountered several times when turning reminders are too slow. In the end, I can only use my mobile phone to navigate directly. You said this was too noisy.

Also, the foot feeling of Tesla Model Y’s switch pedal is also a point that makes people vomit. Compared with other models, you have to spend more effort to step on it. And the feeling of braking feet is very strange, a bit like stepping on a rubber. I think this may be because Tesla used the brakes, which is very different from the traditional mechanical assisted brakes.

Charging speed is also a point I want to vomit. Compared with the new power brands of domestic electric vehicles at the same price, Tesla’s charging speed is indeed a bit behind the rhythm. It’s a terrible headache to have to wait for a long time every time you charge.

Sound insulation and interior are also the two major slots of Tesla Model Y. The sound insulation effect is not good, especially when running at high speed. The noise is unbearable and my ears are about to explode. The simple interior is also an important reason to dissuade many people. The comfort of the seat is not good, the padding of the rear seat cushion is relatively hard, and the backrest angle is also straight, so although the space is large, it is uncomfortable to sit up, just like sitting on a bench.

Having said so many shortcomings, do you think Tesla Model Y is useless? Actually, it is not. It still has many obvious advantages. For example, the chip system is complete, the OTA frequency of car updates is fast, the safety factor is high, and the battery life is stable. Tesla’s three-electricity technology is also relatively strong, and many people buy Tesla. There are also fast after-sales service response, reliable automatic driving, high coverage of charging piles and so on. These are the highlights of Tesla and the reasons why it can stand on the market.

So, is it worth buying Tesla Model Y? There is no standard answer to this question. Because everyone’s needs and feelings are different. For me, although it has some shortcomings that make me headache, it also has some advantages that I can’t give up. So, if you are also considering buying Tesla Model Y, I suggest you take a test drive first, and it is not too late to feel its advantages and disadvantages before making a decision. After all, buying a car is not a trivial matter! You have to think it over carefully!

Master Huang also converted to Rinpoche? I put it this way: "There are also shrines, Buddha statues and incense burning near my home. Then there is also a let-off. So I am still a man of faith. "

He commented on the popular Rinpoche in the market like this:

"I’d rather believe that most of them are real Rinpoche … I also know a famous Rinpoche, which is really coincidental. He has this kind of feeling himself, and people have found him, so he has become a very good Rinpoche before."

This was revealed to reporters by Huang Xiaoming himself when he was promoting the new play "Datang Xuanzang".

Recently, another The Journey to the West IP movie appeared. The production of "Da Tang Xuan Zang" directed by Jianqi Huo and starring Huang Xiaoming was completed, and a promotion meeting was held in Qingdao, the hometown of the founder.

For stars, "filming" is hard, so it is regarded as practice. For example, if you want to shave your head, you will be opposed by the Baby; For example, the weather is very hot, more than 40 degrees, and you have to walk barefoot on the ground; For example, there is no signal, you can’t contact the Baby, and you always walk alone. Huang Xiaoming bluntly said that it feels very lonely …

For another example, Master Huang, who likes to eat meat, also gave up meat!

The hierarch revealed that in fact, there were more famous and large-scale Tang Priest characters who found him, but the hierarch still listened to the voice of "faith" and resolutely chose this austere and seductive version of Tang Priest.

During the filming, he was careful not to eat, and he experienced all kinds of hardships and even recited scriptures every day, which was a blessing for the husband and wife and fulfilled his wish.

Director Jianqi Huo described Huang Xiaoming as silly, with simple eyes, which was very similar to Xuanzang’s obsession. This provoked the cinema colleagues at the promotion meeting to snigger. Huang Xiaoming didn’t want to refute, standing on the stage calmly said, "I am stupid. My mother thinks I should play Xuanzang. I am very similar to him. "

Master version of Wei Xiaobao, unforgettable this clear eyes …

Sina Entertainment commented on the founder: "In the story of the Journey to the West and the hot New Year’s Eve of the monkey Tang Priest, Huang Xiaoming chose Xuanzang without aura-the monkey without reinforcements, almost no beautiful women seducing along the way, no spells to read, and even Bai Longma. Oh, there was a horse, but Xuanzang walked all the time and never got on the horse. "Datang Xuanzang" is such a film that used to learn from the scriptures, relied on transportation, and basically ate soil every day. Under foreseeable circumstances, it is not expected to gain anything at the box office. Perhaps he has made many films such as "The White-haired Witch" and "How to Shengxiao Mo". Xiaoming has been tired of realizing market recognition, and he is gradually giving back. "

There are too many scenes like this …

My heart is so tired …

The following is an interview with the leader by Sina Entertainment:

Huang Xiaoming revealed in the dialogue with Sina Entertainment that he had actually converted to Buddhism, and the fate came many years ago, so he converted in Putuo Mountain. Formed a deeper bond with Buddha,What does Huang Xiaoming think of so many Rinpoches in Weibo?

"Rinpoche is also a human being. He is both a Buddha and a flesh, so he is a flesh Buddha. Then he also has his worldly desires, and he will have his worldly troubles. Then many Buddhists I know, whether they are Buddhists, Buddhists or Rinpoche, will have happy and unhappy times, happy and unhappy times. So in fact, I think people still rely on themselves. Really, I think all practice depends not on others, but on myself. "

Sina Entertainment: I said earlier that filming "Datang Xuanzang" itself was like a practice. What impressed you now?

Huang Xiaoming: I think my inner strength still comes from my understanding of Xuanzang, because our play is adapted from Xuanzang’s biography. When I read Xuanzang’s biography, I was really moved by him. I think we really need this spirit in real life, and we can think about what this setback is. I think you are already a very lucky person, so you will feel that you need to redouble your efforts to do what you are doing now.

Since its introduction to the market, it has been recognized by consumers with its hard-core appearance design and excellent off-road ability, especially in the northwest, and has become a weapon for many off-road enthusiasts to conquer the outdoors at this stage.

In fact, this generation of products has been in the market for a long time. Although the heat is not low, it will still have a certain impact on sales in the face of the impact of new products, especially new energy hard-core products. Recently, a group of spy photos about the new tank 300 were also exposed online.

Through the spy photos, it can be found that the new design scheme still continues the design of the current model. Of course, this "classic" hard-core shape is also the reason why consumers choose him, so the probability of making major changes is very low.

According to the past routine, it can be seen that the camouflage stickers are mainly concentrated in the door position, which is expected to be the focus of the new car upgrade in the future, but there is not much accurate news yet.

The interior is also the place where the new car has changed the most, but it basically focuses on the improvement of details, while the overall outline has not changed.

From the details, it can be found that the central control screen of the new car has also been upgraded from the original embedded to suspended, and its size will be further increased. It is expected to be equipped with the latest in-vehicle intelligent system, which is believed to improve the experience.

In addition, the new car will also be equipped with the latest two steering wheels, and the function buttons on both sides also adopt a more concise wheel operation mode. However, the iconic aircraft push rod block will be cancelled, and the design of the chest block will be adopted in a high probability, so it is expected that the new car will be adjusted on the central island in the future.

As for the power system, it is expected to be consistent with the current model, that is, equipped with a 2.0T turbocharged engine, and matched with an 8AT gearbox, in which the maximum horsepower of the engine is 220Ps and the maximum torque is 380 N m.

summary

For Tank 300, it can also be said that it is the first choice of many off-road mr. six at the current price, and this car has also been in the market for a long time. Judging from the feedback information at this stage, it is indeed a product with excellent quality, and it is indeed a product that can cope with the vast majority of car scenes with the hardcore modeling design.

However, the current development momentum of the new energy hard-core SUV market is extremely strong. For example, the official selling price of Equation Leopard has been lowered to 239,800 yuan, which will undoubtedly have a great impact on the traditional fuel hard-core vehicle market. Therefore, the challenge faced by tank cars is how to stabilize their market position, which has become an urgent problem to be solved.

"Shenjiang No.1" has an average daily excavation of 4.5 meters.

　　In Section 1 of the Pearl River Mouth Tunnel of Shenzhen-Jiangmen High-speed Railway, the shield machine "Shenjiang No.1", a pioneer tool for tunnel excavation, excavates 4.5 meters per day, with a maximum excavation of 12 meters per day. From the gravel sandstone formation where it is located, it will enter the granite area with hard geology 30 rings further.

　　To this end, construction workers are recently replacing the "teeth" of this "dragon"-the blade. After the replacement, it will continue to be put into construction and complete the final attack.

　　Shenjiang high-speed railway is an important part of the coastal passage of China’s "eight vertical and eight horizontal" high-speed railway network. The line starts from the newly-built Shenzhen Xili Station, passes through Dongguan City, Guangzhou City, Zhongshan City and Jiangmen City in the west, and connects to Jiangmen Station. The main line is 116 kilometers long, with a bridge-tunnel ratio of 98%.

　　The line needs to cross the Lion Ocean in the Pearl River Estuary. The Pearl River Mouth Tunnel, one of the control projects in the whole line, has a total length of about 13.7 kilometers, a maximum depth of 106 meters and a maximum water pressure of about 1 MPa. It is the deepest subsea tunnel in China at present.

　　The tunnel is designed as a single-hole double-track high-speed railway tunnel. The diameter of shield machine excavation is about 13.4 meters. The shield segments are designed with nine equally divided structures, and the capping blocks are also larger than the conventional design size. It is a large-diameter shield tunnel.

　　Moreover, the geological conditions it crosses are very complicated, and it needs to cross 13 kinds of strata, 5 kinds of composite geology and 17 fault zones, such as silt, soft sand and extremely hard bedrock uplift. The full-face hard rock excavation is about 2.8 kilometers long, and the maximum strength of granite is 124.6 MPa.

　　According to the characteristics of the project, the Pearl River Mouth Tunnel of Shenjiang High-speed Railway adopts the combined construction method of "shield at both ends+middle mine". The starting shafts of shield at both ends are located in Humen Town, Dongguan City, on the east side of the estuary, and Wanqingsha Town, Guangzhou City, on the west side. Two tailor-made domestic shield machines-"Shenjiang No.1" and "Shenjiang No.2" came into being, heading in opposite directions. In Nansha District, Guangzhou, an inclined shaft is set up, which is constructed from the middle to both sides by mining method to connect the tunnels dug by shield machines.

　　Shield construction is safe and controllable in quality.

　　Shield tunneling, synchronous grouting, segment assembly and box culvert assembly are the four main processes of shield construction. Each working procedure should follow the corresponding standardized operation flow to ensure the safety and quality control of shield construction.

　　The pipe wall of the Pearl River Mouth Tunnel is composed of precast segments made of reinforced concrete.

　　In the face of high water pressure and high corrosion environment, the segment adopts gasket and anti-corrosion technology, which greatly improves the waterproof, anti-corrosion and anti-seepage performance of the tunnel. At the same time, the synchronous grouting process is strictly controlled, and the connection between the formed tunnel and the external water system is isolated, so that the tunnel is impermeable and leakproof.

　　The front end of "Shenjiang No.1" shield machine is where its main drive and central cone are located, and the central cone is connected with the cutter head.

　　Among them, the main drive is the core and most precise component of the shield machine, and it is also the key of the whole pressure-resistant system. "Shenjiang No.1" shield machine is equipped with the main drive seal automatic pressure maintaining system, which can effectively cope with the excavation in high water pressure environment. It is also equipped with an on-line oil detection system to realize the on-line inspection of the "blood index" of the main drive and ensure that the core components of the main drive are normal.

　　Technological innovation runs through the whole process of shield tunneling.

　　In order to adapt to the seabed conditions, "Shenjiang No.1" has adopted a number of technologies with independent intellectual property rights-high-precision gas-liquid pressure balance control technology of the excavation bin to ensure the stability of the excavation bin in the subsea shield construction.

　　Informatization and intellectualization always run through the process of shield tunneling. "Digital Deep River" information platform realizes BIM visual application platform and remote control of shield machine. On the screen of the cab, real-time monitoring system of shield tunneling parameters, advanced geological prediction system of shield tunnel, cutter head and cutter wear monitoring system of shield machine, main drive seal monitoring system, shield equipment maintenance management system and grouting density detection system behind segment wall are displayed respectively.

　　The data of these systems will be transmitted back to the digital shield module of BIM visualization application platform, and the excavation of large shield projects can be monitored remotely through digital shield.

　　Around shield construction, technicians provide a series of support services from data collection, application analysis to decision optimization, so as to guide shield tunneling construction quickly and accurately and ensure construction safety.

　　BEIJING, Beijing, November 17 (Reporter Zhang Ni) On the 17th, the reporter learned from the Beijing Center for Contradiction Analysis and Research of Letters and Calls that the Beijing Letters and Calls Office is actively building a big data analysis platform for "smart letters and visits". In the future, the platform can monitor and accurately predict the petition situation in real time through machine learning and artificial intelligence big data analysis technology.

　　On the 17th, the Beijing Center for Contradiction Analysis and Research of Letters and Visits held an expert review meeting on the acceptance of the capital’s "smart letters and visits" big data analysis platform project in Beijing. At the meeting, the platform passed the acceptance and is expected to be officially put into use from the beginning of December.

　　The reporter learned from the meeting that in order to grasp the key to the development of letters and visits in the new era, Beijing Letters and Calls Office has actively built a "smart letters and visits" big data analysis platform, and the specific construction of the platform is under the responsibility of Beijing Letters and Calls Contradiction Analysis and Research Center.

　　According to reports, the platform will monitor and accurately predict the situation of letters and visits in real time through machine learning and artificial intelligence big data analysis technology, which can not only grasp the development trend of letters and visits at any time, grasp the signs of extreme events, but also predict the possibility of future development of letters and visits from the source, so as to plan ahead and resolve the contradictions and conflicts between letters and visits in the bud.

　　Specifically, the big data analysis platform of "smart letters and visits" in the capital mainly includes two functions, namely "deep mining" and "situational awareness".

　　Among them, "deep mining" refers to the use of text mining and advanced NLP natural language algorithm to analyze the feelings expressed by the petitioners’ sentences and words in letters, eliminate subjective prejudice, and discover the objective laws of petition data based on artificial intelligence. The study of the emotional tendency of the complainant can better describe the "portrait" of the complainant.

　　"Situation awareness" mainly includes two aspects. On the one hand, it means that on the basis of "deep excavation", the platform can make correlation analysis of events and predict the trend of letters and visits, thus laying a solid foundation for accurately investing in letters and visits resources. On the other hand, through text mining, the key words of letters and visits are captured, and relevant laws and similar cases are automatically and real-time pushed for business workers as work reference.

　　In addition, in order to transform the petition data into multi-level and multi-dimensional information, reveal the logical connection behind the data, and then promote scientific decision-making, the Beijing Center for Contradiction Analysis and Research of Letters and Visits put forward the concept of "petition index" in 2011, and began to study the petition index in 2012.

　　Based on the data of letters and visits, this study aims to construct letters and visits indicators through the quantity and quality of letters and visits, quantitatively present the current situation, characteristics and development trend of social risks, build an objective and scientific evaluation standard and system for letters and visits, and enhance the forward-looking, systematic and targeted work of letters and visits. At present, the "index of letters and visits" has the foundation to be popularized throughout the country.

　　Experts attending the meeting commented that the two major innovations, namely, the big data analysis platform of "Smart Letters and Visits" and the application system of letters and visits index, have become the first step towards the era of artificial intelligence in the field of letters and visits in China, which is also a crucial step. This will fundamentally change the dilemma of passive response and resource consumption in traditional petition work, and open a new mode of petition work with active response and accurate allocation of resources.
