Automatic vehicle identification system with active RFID technology

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 or wrong inspections, and various disputes caused by unclear identification are greatly reduced. It can not only improve work efficiency, but also strengthen the management of the traffic police department. Carry out effective and 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 they have a very huge market. However, the vehicles on the road are often uneven, including fake cars, fake cars, smuggled cars, accident-causing cars, illegal cars, black cars, scrapped cars, etc. These undoubtedly pose major hidden dangers to road traffic and bring great harm to people's property. cause losses. Traffic violations such as intruding into 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, seriously disrupting the market. improve the passenger transport market and operational order. However, these cars are often modified and modified. In this case, it is sometimes difficult for traffic police officers to identify them with only the naked eye. To identify them, they often have to rely on manual parking inspection and management at close range, which undoubtedly creates problems for the traffic police. It increases labor intensity and also brings adverse effects to legal vehicle parking inspections. Therefore, we need to use scientific and technological means to manage this, so that the traffic police can quickly and accurately determine whether the car is legal. In a certain sense, it can also improve social security, reduce vehicle robbery and theft cases, reduce people's property losses, or reduce people's property losses when they occur. In such cases, the detection rate can be improved.

The RFID vehicle long-distance identification system has been successfully used in parking lots, parking lots and container vehicles. After application, the management efficiency of vehicles has been significantly improved and intelligent vehicle management has been provided. The RFID identification system collects fully automated data on vehicle entry and exit. On the one hand, it greatly improves the image of establishing a new urban vehicle management, prevents loopholes in manual operations, facilitates data archiving, and ensures the safety and reliability of vehicle information. On the other hand, it greatly promotes It has accelerated the pace of automation construction in cities and government enterprises.

Provide strong technical support for applications in the fields of long-distance signal recognition and data transmission, and provide the best solutions for modern vehicle management.

Summary, we are trying to solve the problem of "stopping inspection" under normal conditions and realize "customs clearance without stopping".

2. System Introduction

This system makes full use of RFID technology. As a high-tech company specializing in the research and development of long-range radio frequency identification technology, we launched RFID after comprehensively considering the advantages and disadvantages of each product technology and its practical application. We adopted today's advanced 0.18uM chip technology to make RFID more practical. The performance has been substantially improved, creating a new era of long-distance identification technology. It completely solves the identification problems of long-distance, large-traffic, anti-interference, ultra-low power consumption, and high-speed moving markers, and the cost is greatly reduced than before. It provides very advanced and effective technical support for applications in long-distance identification, positioning, tracking, and data transmission of people, vehicles, and objects.

1. Introduction to system functions

This system is suitable for inspecting undesirable phenomena in vehicles, such as inspecting fake and counterfeit vehicles, inspecting illegal and hit-and-run vehicles, inspecting other types of illegal vehicles, and other extended functions.

Install an active long-distance identification card behind the internal windshield of a legal vehicle that records the vehicle information and owner information. The management platform and data server will promptly download the corresponding information to each inspection system (handheld PDA remote reading Card device); on the premise that all legal vehicles are equipped with long-range 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 that do not match or cannot receive electronic information are fake or counterfeit vehicles; the vehicle-mounted inspection system or the fixed inspection system automatically compares the physical characteristics and electronic information of the specified vehicle through the image recognition system and the electronic information receiving system, and the information If the vehicle is inconsistent or the system only receives image information, it is a fake or fake vehicle. The system will immediately give voice and digital display alarms, and law enforcement officers can promptly implement interception and inspection or notify law enforcement officers at the next intersection to conduct interception and inspection.

A) Inspection of stolen and smuggled vehicles

The license plate number and other information of the stolen vehicle will be entered into the audit system through the management platform, and added to the blacklist. If the stolen vehicle retains its original license plate number, the system can immediately detect and alarm when it enters the audit range. ;If the original license plate number is not used, it will be regarded as fake and the fake license plate will be identified and intercepted. After further checking the vehicle characteristics, it can be determined whether it is a stolen vehicle. For smuggled cars, since they cannot obtain legal license plates, they can only be fake or fake cars, and they will also be seized in time.

B) Inspection of traffic violations and hit-and-run vehicles

Information such as license plate numbers and violation records of vehicles that violate regulations and hit-and-run accidents are entered into the inspection system through the management platform and added to the blacklist. When such vehicles enter the inspection range, the system can detect them immediately and prompt the vehicle characteristics and In cases of traffic violations, hit-and-runs, etc., law enforcement officers can immediately intercept the vehicle.

C) Inspect other types of illegal vehicles

The system can also enter the vehicle and owner information of problematic vehicles such as scrapped vehicles, vehicles without annual inspections, vehicles with arrears of payment and taxes, etc. into the management platform and add them to the blacklist. When these problematic vehicles enter the inspection scope, the system can detect them immediately. It also prompts the characteristics of the vehicle and its violations, so that 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 add functions required for traffic management and public safety, such as non-stop toll collection on highways, community and parking lot access management, vehicle driver identity determination, etc.; combined with GPRS technology, it can be implemented Remote vehicle status monitoring, remote stalling of stolen vehicles, automatic notification of vehicle violations, etc.

2. Working principle

The core technology of the vehicle identification management system is the automatic identification and automatic discrimination of vehicles. The automatic vehicle identification system (Automatic Vehicle Identification-AVI) based on active RFID technology includes vehicle-mounted radio frequency tags, fixed base station AVI, and handheld base station AVI system.
