1. System overview
At present, my country’s economy is developing rapidly and people’s living standards are rapidly improving. Motor vehicles have become standard consumer goods for urban and rural residents. This can be seen from the unusually congested domestic urban traffic in recent years and the vigorous car-making movement in various places. However, for the governments of various parts of our country, if the transportation is not well controlled, the harm is far greater than the benefits of the transportation itself. How to manage these increasing motor vehicles has become a difficult problem. With the increase in the number of motor vehicles, the illegal activities of vehicles have become more and more serious. Their behaviors mainly include counterfeiting/arrangement, theft and smuggling of smuggled vehicles, evasion of vehicle and vessel use tax and compulsory insurance, arrears of traffic violation fines, traffic accident escape and wanton violations. Wait. According to statistics, vehicles that are stolen and smuggled are basically fake/deck plates; vehicles that evade vehicle and vessel use tax and compulsory insurance are basically stolen, rob and smuggled vehicles; vehicles that violate regulations and are not afraid of traffic violations are mainly fake vehicles. / Deck car. Therefore, to solve the problem of vehicle violations in our country, one is to promote traffic laws to the majority of car owners and drivers, popularize knowledge of traffic laws, and enhance their awareness of compliance with laws and regulations; / Problems with decked vehicles.
The amendment (draft) to the “Road Traffic Safety Law of the People’s Republic of China” that has been implemented since May 1, 2011 pointed out that “in view of the increasing social harm of forgery, alteration of motor vehicle license plates and illegal use of fake license plates, the road There is an obvious incompatibility between penalty and transgression in Article 96 of the Traffic Safety Law. In order to effectively punish this illegal act, the Road Traffic Safety Law Amendment (Draft) has made the following changes: If the motor vehicle registration certificate, number plate, driving license, or driver’s license are forged, the penalty for 15 days’ detention will be increased, and the fine will be increased from 200 yuan to 2,000 yuan to 2,000 to 5,000 yuan; for forgery, alteration or The use of forged or altered inspection marks and insurance marks has increased the penalty for detention for less than 10 days, and increased the fine from 200 yuan to 2,000 yuan to 1,000 to 3,000 yuan; for motor vehicles that use other vehicles For registration certificates, number plates, driving permits, inspection marks, and insurance marks, the fine will be increased from 200 yuan to 2,000 yuan to 2,000 yuan to 5,000 yuan.” At present, there are about 106 million cars in the country. If you calculate that fake/deck-licensed vehicles account for 3% of the country’s car ownership, there are about 3.18 million cars in the country. If the use tax is 480 yuan and the compulsory traffic insurance is 900 yuan, the country will lose about 4.39 billion yuan each year, which does not include the purchase tax and the annual vehicle inspection fee.
What’s more serious is that the use of fake/deck-licensed vehicles on the road will cause great potential harm to the society, and many legitimate vehicle owners have been punished for unwarranted reasons for the illegal activities of unlicensed vehicles. At the same time, the main purpose of many behaviors of covering the number plate, altering the defaced number plate, and altering the number plate is to avoid illegal restrictions. When a traffic accident occurs and there are favorable conditions for escape, it will pose a safety threat to other traffic participants. The victim caused physical and mental losses, and at the same time brought major hidden dangers of traffic accidents.
Although the local public security traffic management departments have continuously carried out special operations against license plate vehicles, after each operation, the phenomenon of license plates, fake military (civilian) license plates, deliberate obstruction of license plates, alteration of license plates, and alteration of license plates continue to occur after each operation. happens sometimes.The fundamental reason is that the public security traffic management department has no effective means to check illegal and counterfeit vehicles.
At present, how to use high-tech means to provide effective inspection methods for the public security department to quickly detect fake/deck-licensed vehicles, stolen vehicles, etc. is imminent. Aiming at the actual situation of repeated prohibitions and repeated violations of the phenomenon of unlicensed vehicles, in order to effectively protect public safety and maintain traffic order, Xintai’s self-developed “Motor Vehicle Electronic Driving Permit Information Management System” uses radio frequency identification technology as a data collection method. Internet network and database technology are data support to build a motor vehicle electronic driving permit information management system, storing the vehicle information in the existing driving permit in the electronic tag chip in the electronic driving permit, and identifying the true identity of the vehicle through the electronic tag , So that there is no hiding place for fake/decked vehicles, stolen and robbed vehicles, and effective technical preventive measures are used to combat and rectify fake/decked and other illegal vehicles, improve the traffic management system, realize information management, and improve the modernization of traffic management level.
Xintai Company has extensive industry experience in the field of intelligent transportation. The Inner Mongolia Autonomous Region Public Security Department’s application innovation project “Radio Frequency Identification-based Driving License Anti-counterfeiting Management System” undertaken by Xintai Company passed expert acceptance in June 2012, and its scientific and technological achievements have been Register with the Ministry of Public Security.
1. Construction goals
This project aims to use advanced radio frequency automatic identification technology,RFIDService bus technology, low-power control technology, embedded real-time system, mobile communication network, distributed software platform and other high-tech, provide efficient and scientific motor vehicle supervision and application solutions, and improve government functions such as public security, industry and commerce, taxation, etc. The management level and efficiency of motor vehicles will enhance the overall image of the government.
2. Significance and necessity of system construction
According to the statistics of my country’s traffic police department, fake and unlicensed vehicles have become the number one road killer in various parts of our country. Worse still, fake and unlicensed vehicles escaped after causing traffic accidents, which seriously affected traffic order and traffic safety. There are two reasons why motor vehicles use fake and decked licenses: one is the wrong way or the procedures are not complete; the other is to evade various fees. Commercial vehicles, smuggled vehicles, assembled vehicles, scrapped vehicles, and stolen vehicles are the mainstays of this type of vehicle. The most common phenomenon is the phenomenon of licensing. When buying a car, buy two vehicles of the same model and color, and buy fake license plates and driving permits from criminals. These black cars and cloned cars have already brought serious harm to the traffic and passenger transport market. How to use technical preventive measures to combat and rectify the decking phenomenon is particularly important.
Therefore, it is very necessary to realize the electronic management of vehicles with electronic tags with high-speed and long-distance automatic identification, large-capacity information storage and advanced anti-counterfeiting technology. Electronic tags can carry many information about the vehicle in the form of electronic information, such as license plate number, car model, body color, engine number, frame number, violation handling, annual inspection records, etc. It has the only number in the world that cannot be copied or rewritten. The writing must be recognized by the special equipment and business management system of the vehicle management office, thus effectively preventing the possibility of forgery and tampering of license plates. As long as the public security traffic management department deploys the electronic driving permit system at various road and bridge toll stations, main roads, and urban entrances and exits in the city, it can automatically identify the legitimacy of the vehicle without stopping; at the same time, the public security traffic management department can also use mobile inspection methods. The use of vehicle-mounted and hand-held readers to interrogate illegal vehicles at major intersections, parking lots and other places in the city makes it difficult for black and cloned vehicles to exist in the market.
2. The working principle of the system
“Motor Vehicle Electronic Driving Permit Information Management System” completes the issuance of the electronic driving permit through the electronic certificate business management system, and writes the license plate number, vehicle type, owner, contact address, and use to the electronic tag chip embedded in the electronic driving permit Nature, vehicle brand, vehicle model, body color, engine number, frame number, registration date, issuing authority, initial registration date, file number, approved number of passengers, total mass, approved load quality, curb weight, outline dimensions, Remarks the mandatory obsolescence period, inspection records and other vehicle information and label issuance date, label issuing personnel, validity period, issuing department, annual inspection validity mark, label validity mark and other label information, and all information is encrypted. Then install the RFID electronic license plate on the front windshield of the vehicle. At this time, the vehicle has a unique ID card.
Install recognition systems at all intersections, roads and other places where electronic license plates need to be recognized, and the recognition system operates around the clock. When a vehicle equipped with an electronic driving permit enters the identification area, the video device is activated to capture images of license plates; at the same time, the RFID reader is activated and automatically scans the electronic tag. The reader is controlled to send out a microwave query signal and install it in front of the vehicle. After receiving the inquiry signal from the reader, the electronic tag on the windshield reflects the data information in the tag back to the reader. Its energy supply and data exchange with the reader are realized through electromagnetic fields. The system uploads the captured license plate image and the recognition result of the corresponding electronic driving license to the management center for comparison. First, the RFID reader will determine whether the tag is a legal tag (including whether the tag is forged and whether the vehicle carries the tag). If so, it will determine whether the physical license plate and the license plate information stored in the electronic tag are based on the result of the comparison by the management center Consistent, if they are consistent, you can continue to access the “blacklist” record in the information management system through wired or wireless access, which records “no annual inspection”, “not paid for fines”, “scrapped vehicles”, “not paid for compulsory insurance “,” “Unpaid vehicle and vessel use tax”, “Unpaid purchase tax” and other illegal vehicle information, if it is not among them, then let go; if any of the above conditions are not passed, local alarm will be immediately issued, and wired or wireless access Alarms were made in the center and recorded accordingly, and the front-end law enforcement officers were further punished in accordance with the laws and regulations of the country as prompted by the reader.
When a vehicle without an electronic license plate enters the system, the vehicle information will not be displayed, and an illegal vehicle intrusion may be prompted. For vehicles whose license plate information is consistent with the information stored in the database, when passing through the toll gate channel, the management mode of automatic inspection and automatic release for one vehicle and one pole is implemented.
Front-line law enforcement officers can complete on-site law enforcement through the mobile inspection system. Using the on-board system, law enforcement officers can set up law enforcement points at major intersections in the city to inspect illegal vehicles; they can also use handheld readers to judge vehicle tags in parking lots of office buildings and shopping malls. Comparing the license plate information in the electronic driving license with the physical license plate information read by the naked eye, if it is inconsistent, you can complete further enforcement operations in accordance with the laws and regulations formulated by the Public Security Traffic Administration.
The block diagram of the working principle of this system is shown in the figure below:
The electronic driving permit is packaged in PET material with a non-contact electronic tag chip embedded. As shown below:
“Motor Vehicle Electronic Driving Permit Information Management System” is a part of the entire public security traffic information system. Its design is matched with the overall electronic traffic management project. The operation of the system is directly related to every driver, public security officer and society. The vital interests of the masses, the prestige of honor, and the safety of life are a wide-ranging, politically intricate and complex system project. Facing such a systematic project involving the whole society, the system adopts advanced technical equipment and technical means to ensure the reliability, safety, advancement, adaptability and scalability of the system, so as to provide high-quality and efficient services to the society.
