　　Working principle of active RFID technology system

　　The automatic vehicle identification system (Automatic VehicleIdentification-AVI) based on active RFID technology includes vehicle radio frequency tags, fixed base station AVI, and 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 investigations, 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 carry out 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-M4000PPDA 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.
