1. System overview
Vehicle management is the use of RFID technology to intelligently and effectively manage all vehicles within its jurisdiction. Due to the use of machines for identification, the identification rate is increased to avoid missed and mis-checked phenomena, and various disputes due to unclear identification are greatly reduced. This can not only improve work efficiency, but also strengthen the management of the traffic police department. Carry out effective management of urban taxis to protect the interests of the country and the people.
In modern society, cars have become one of the indispensable means of transportation for people to travel, and have a very huge market. However, the vehicles on the road are often uneven, such as fake cars, illegal cars, smuggled cars, cars that have caused accidents, illegal cars, black cars, scrapped cars, etc., which undoubtedly lay a major hidden danger to road traffic and bring people’s property. Cause losses. Traffic violations such as trespassing in restricted areas and speeding are particularly prominent in 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. However, these vehicles are often modified and modified. In this case, it is sometimes difficult for traffic police officers to distinguish them with the naked eye. To identify them, it is often necessary to rely on the traffic police’s close-range manual parking inspection management, which is undoubtedly for the traffic police. Increased labor intensity, but also has a negative impact on legal vehicle parking inspections. Therefore, we need to use technology to manage this, so that the traffic police can quickly and accurately determine whether the car is a legal car. In a certain sense, it can also improve social security, reduce vehicle robbery and theft, and reduce people’s property losses, or if it occurs In such cases, the detection rate can be increased.
The RFID vehicle long-distance identification system launched by Suzhou Mulan Electronic Technology Co., Ltd. has been successfully applied to parking lots, parking lots and container vehicles. After the application, the management efficiency of vehicles has been significantly improved and intelligent vehicle management has been provided. The RFID identification system fully automates the collection of vehicle entry and exit data. On the one hand, it greatly improves the image of establishing a new urban vehicle management, prevents manual operation loopholes, is conducive to data archiving, and ensures the safety and reliability of vehicle information. On the other hand, it greatly promotes This has improved the pace of automation construction in cities and government enterprises.
The emergence of Mulan electronic technology will provide strong technical support for the application of long-distance signal recognition and data transmission, and provide the best solution for modern vehicle management.
In summary, we are to solve the problem of “parking inspection” under normal conditions and achieve “non-parking inspection clearance”.
2. System introduction
This system makes full use of ML-RFID (Mulan Radio Frequency Identification) technology. As a high-tech company dedicated to the research and development of long-distance radio frequency identification technology, we launched “ML-RFID” after integrating the advantages and disadvantages of each product technology and actual application, using today’s advanced 0.18uM chip technology , Which has substantially improved the performance of RFID and created a new era of long-distance identification technology. It completely solves the identification problems of long-distance, large-flow, anti-interference, ultra-low power consumption, and high-speed moving markers, and the cost is relatively high. It has been greatly reduced in the past. It provides a very advanced and effective technical guarantee for the use of long-distance recognition, positioning, tracking, and data transmission of people, vehicles, and objects.
1. System function introduction
The system is suitable for the inspection of vehicle undesirable phenomena, such as the inspection of fake and unlicensed vehicles, the inspection of illegal and hit-and-run vehicles, the inspection of other types of illegal vehicles, and other extended functions.
Install an active long-distance identification card recording the vehicle information and owner 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 PDA remote reading Card device); 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. Law enforcement officers compare the physical characteristics of the vehicle with the displayed vehicle information Those who do not match or cannot receive electronic information are fake and unlicensed vehicles; the vehicle inspection system or fixed inspection system automatically compares the physical characteristics and electronic information of the designated vehicle through the image recognition system and the electronic information receiving system. If the vehicle is inconsistent or the system only receives image information, it is a fake or de-licensed vehicle. The system will immediately give an alarm with voice and digital display. Law enforcement officers can implement interception inspection in time or notify Xiayikou law enforcement officers to implement interception inspection.
A) Inspection of stolen and smuggled 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. The license plate car is 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.
B) Inspection of illegal and hit-and-run vehicles
The license plate number and violation records of vehicles that violate regulations and hit-and-run escapes are entered into the inspection system through the management platform, and added to the blacklist. When such a vehicle enters the inspection scope, 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.
C) 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 detect them immediately. It also prompts the characteristics of the vehicle and its violations, and law enforcement officers can immediately intercept and enforce the law.
D) Other extended functions
The system provides a variety of functional interfaces, which can easily increase the functions required for traffic management and public safety, such as expressway non-stop toll, community and parking lot access management, vehicle driver identity determination, etc.; combined with GPRS technology, it can be realized Remote vehicle status monitoring, remote shutdown of stolen vehicles, automatic notification of vehicle violations and other functions.
2. Working principle
The core technology of the vehicle identification management system is the automatic identification and automatic discrimination of vehicles. 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.
