1. System introduction
The system uses the world’s leading microwave frequency band long-distance radio frequency identification technology, and each vehicle is equipped with an active proximity card (ML-T80) registered in the system in advance. The active proximity card will continuously emit microwave signals. When the nearby long-distance reader (handheld ML-M4000P) receives the proximity card signal, the long-distance reader will automatically compare the information with the control center through GPS/GPRS. Recognize and judge the legality of the card. If it is legal, it is allowed to pass. Otherwise, the handheld reader will give an alarm and automatically record the vehicle information. The handheld remote reader can be carried by the inspection staff to monitor the vehicle anytime and anywhere, including information such as the vehicle department, driver’s name, license plate, and photo.
2. System function introduction
The system is suitable for the inspection of vehicle undesirable phenomena, such as inspection of fake and unlicensed vehicles, inspection of illegal and hit-and-run vehicles, inspection of other types of illegal vehicles, and other extended functions, etc.
Inspection of fake and unlicensed vehicles
Install an active long-distance identification card recording the vehicle information and owner’s information behind the internal windshield of a legal vehicle, and the management platform and data server will download the corresponding information to each inspection system in a timely manner (handheld remote card reader Or fixed long-distance card reader); under the premise that all legal vehicles are equipped with long-distance identification cards, the handheld inspection system receives electronic information and displays the corresponding vehicle information. Vehicle information is compared, and those that do not match or cannot receive electronic information are fake and unlicensed vehicles; the on-board inspection system or fixed inspection system uses the image recognition system and the electronic information receiving system to conduct the physical characteristics and electronic information of the designated vehicle. Automatic comparison, the information is inconsistent or the system only receives the image information is a fake, decked vehicle, the system will immediately voice and digital display alarm, law enforcement officers can implement timely interception inspection.
Check the robbery and smuggling of vehicles
Pass the stolen vehicle’s license plate number and other information through the management platform, enter it into the inspection system, and add it to the blacklist. If the stolen vehicle uses the original license plate number, the system can immediately detect and alarm when it enters the scope of the inspection ; If the original license plate number is not used, it will be regarded as a fake, and the license plate car will be identified and intercepted. After further checking the characteristics of the vehicle, it can be determined whether it is a stolen vehicle. For smuggled vehicles, because they cannot obtain a legal license plate, they can only be fake and unlicensed vehicles, and they will also be seized in time.
Inspection of illegal and hit-and-run vehicles
Information such as the license plate number and violation record of the vehicle that violates regulations or hits and escapes is entered into the inspection system through the management platform, and added to the blacklist. When such a vehicle enters the scope of the inspection, the system can immediately detect it and prompt the characteristics and characteristics of the vehicle. Law enforcement officers can immediately intercept violations, hit-and-run situations, etc.
Check other types of illegal vehicles
The system can also record the vehicle and owner information of problem vehicles such as scrapped vehicles, vehicles that have not been inspected annually, vehicles in arrears and taxes, etc., into the management platform, and added to the blacklist. When these problematic vehicles enter the scope of inspection, the system can instantly detect, It also prompts the characteristics of the vehicle and its violations, and law enforcement officers can immediately intercept and enforce the law.
Other extended functions
The system provides a variety of functional interfaces, which can easily increase the functions required by traffic management and public safety, such as expressway non-stop charging, community and parking lot access management, vehicle driver identity determination, etc.; combined with GPS and GPRS technology, It can realize the functions of remote vehicle status monitoring, remote flameout of stolen vehicles, and automatic notification of vehicle violations.
In addition to annual vehicle insurance, road maintenance fees, vehicle tolls, taxes, and operating expenses, “black cars” can also reduce the cost of annual vehicle inspections by the traffic police department and the annual review of the driver’s license for one year. It can save a few thousand yuan to tens of thousands of yuan; and a “black car” used for operation can escape up to tens of thousands of yuan each year.
After the illegal traffic violations of licensed vehicles are photographed by the electronic police, the original owner must be the one who received the ticket; what’s more serious is that once the licensed vehicles cause a traffic accident, most of them will choose to escape, and it is difficult for the traffic police to find the real perpetrators. The real car owner will suffer injustice.
Traffic violations such as trespassing in restricted areas and speeding are particularly prominent among various “black cars”; for “black cars” engaged in passenger transportation, due to their low cost, car owners usually compete viciously with regular operating vehicles at lower prices, causing serious disturbances. Improved the passenger transport market and operational order.
Three, system composition
1. ML-M4000P handheld reader; 2. 2.45G long-distance vehicle electronic tags; 3. System management software (1 set) 4. Handheld reader/writer wince software (1 set) 5. System computer control center
Fourth, the working principle of the system
Automatic vehicle identification system based on active RFID technology (Automatic Vehicle Identification -AVI), including vehicle radio frequency tag, fixed base station AVI, handheld base station AVI system. Here we introduce the handheld method.
1. The electronic identification card is an active electronic radio frequency card with a power of about 1/1000 watts. Its memory can be used to store various information including vehicle model, license plate number, and relevant information of the owner. It is a complete car Identity cards and credit cards.
2. Handheld AVI system: In some applications, such as public security criminal investigation, road inspections, and important meeting security, it is necessary to be equipped with a handheld AVI system, which can be started and parked at the designated roadside (or entrance of the venue) at any time to conduct surprise attacks on passing vehicles Check and identify. The handheld AVI system uses a mobile phone to send short messages (or other methods) through the mobile communication network (GSM) to maintain communication with the system control center or exchange data information. If you need to report the location of the handheld AVI system, the car can also be equipped with a GPS receiver to send a short message via GSM to transmit the location of the mobile station to the command center. In some applications, simple mobile inspection equipment (ML-M4000P PDA handheld reader) can also be used. Inspectors can use PDA readers to check passing vehicles in certain narrow areas. The PDA reader has downloaded the vehicle information in advance, and once it reads illegal information, it will immediately call the police.
Five, program features
Long distance: easy to achieve within 10 meters of reading distance. Due to the actual requirements of vehicle identification, the card reading distance should not be too long. This solution does not need to be manually approached to swipe the card or to pass in a designated area to be recognized. Fully automatic recognition is realized, which can avoid problems such as the driver having to move the window close to the reader to swipe the card in bad weather. Advanced anti-collision technology supports multi-label recognition and writing, which can effectively alleviate the jam problem caused by too many vehicles entering and exiting the warehouse and queuing credit cards during peak hours;
Stable operation: The active card has a stable reading distance and is not easily affected by the surrounding environment. Moreover, the active card can effectively break through the shielding effect of the automobile’s explosion-proof metal mesh, and smoothly exchange data with the reader. Using channel isolation technology, multiple devices do not interfere with each other;
Support high-speed mobile reading: The identification card can move at a speed of up to 200 km/h.
High reliability: it can operate normally within the ambient temperature of -40℃-85℃ (MTBF≥70000 hours), especially in the low temperature in the north and high temperature in the south, it has more advantages, which can effectively resist the high dust in the air in the coal mine environment It can ensure the normal use of the equipment in environments such as pollution and rain.
Encrypted calculation and authentication to ensure data security and prevent link eavesdropping and data cracking;
High anti-interference and lightning protection design: There are no special requirements for various interference sources on site, meeting the requirements of the industrial environment, and the installation is convenient and simple.
There is no need to apply for and pay for the ISM microwave frequency band that is open worldwide.
Ultra-low power consumption: long service life, low average cost, and it is safer and healthier for the human body without radiation damage. Configurable microwave module working mode, adjustable transmission power;
Multi-identification: It can identify more than 200 signs at the same time. If there are more than 200 signs on the spot, we have a way to deal with it.
