Second, the system architecture
The system is mainly composed of entrance card reader, controller equipment, entrance railing machine, exit card reader, exit railing machine, charging and monitoring management center. For the one-in-one-out system, its structure is as shown in the figure below:
The entrance (exit) system deployment is shown in the figure below:
The entire management system consists of 4 parts.
(1), electronic identification card (electronic license plate)
The electronic identification card is a passive electronic radio frequency card with a radio frequency of 860-927Mhz and a memory of 256bit. It can store various information including vehicle model, license plate number, and relevant information of the owner. It is a complete car identification card and credit card. This kind of label can be packaged into different forms depending on the placement position. For example, the label placed behind the windshield can be made into a transparent glass label, and the label placed on the roof or the side of the car body can be sealed into a metal label to enhance the communication effect.
(2), RFID long-distance reader
The RFID reader is a device with a microwave circuit, which is used to establish directional high-frequency microwave communication with the identification card. It has strong anti-jamming performance and fast communication capabilities, and can adapt to the management of sports vehicles. This kind of reader usually uses an external antenna to complete the radio frequency communication with the identification card. For example, Fuen’s UHF reader is a radio frequency identification device specially developed for vehicle management, with a reading distance of 8 meters and a vehicle moving speed of 120km/h during reading and writing.
(3) Microprocessor for communication processing
It interprets the information from the identification card and transmits it to the lane controller, so as to obtain the relevant information of the vehicle and perform corresponding processing. After analyzing the data information from the lane controller, the data in the identification card can be modified as necessary. .
(4) Lane controller
According to the information on the card, it can determine whether the passing vehicle has the right to pass normally. It can also determine the validity of the card, activate the corresponding traffic signs or open the barriers, etc., or issue a warning to the owner of the necessary prompts.
