Long-distance radio frequency identification (RFID Reader) technology is the most advanced fourth-generation automatic identification technology in the world. It has the characteristics of long recognition distance, high recognition accuracy, fast recognition speed, strong anti-interference ability, long service life, penetrating non-metallic materials, etc., and has a wide range of applications.

At present, the parking lot is managed manually. When there are vehicles entering and exiting, the automatic retractable doors need to be manually controlled, and whenever there are foreign vehicles entering and exiting, the administrator can only register one by one, which is very time-consuming and laborious, and there will inevitably be artificial When it's wrong. It is no longer sufficient to rely on traditional vehicle monitoring and management to ensure timely and effective recording of incoming and outgoing vehicles. In this regard, we use RFID wireless radio frequency technology to manage the vehicle. This system allows the guards to monitor the vehicle in real-time, saving the time of vehicle entry and exit, and greatly reducing the management work intensity.

The RFID intelligent parking lot management system not only retains all the functions of the traditional parking lot management system but also relies on the original charging media to improve the management media. When the vehicle enters the parking lot, the system automatically captures the vehicle image, obtains the vehicle model, license plate, and color information after computer processing, and stores this information in the database together with the unique correspondence of the user card. When the vehicle leaves the parking lot, the user card, license plate number or vehicle image, and other relevant indicators can only be released after matching.

　　The performance characteristics of the intelligent parking lot system are as follows:

　　 1. Using radio frequency identification technology and computer control, it has a high degree of automation and accurate control.

　　2. It adopts long-distance intelligent identification label technology with good anti-counterfeiting performance. The parked vehicle has a tag card with a unique serial number, and the serial number cannot be changed. Multiple encryption technologies, unique identification, can not be imitated. And only the system is issued and approved.

3. When the non-contact smart tag card is used, there is no mechanical contact action, long-distance induction communication, no directionality, the card can be read within the long-distance reading range of the reader, and the card can be read without stopping the vehicle. Operation is convenient for users.

　　4. The barrier automatically raises and lowers according to the traffic situation of the vehicle, and has the function of anti-smashing.

　　 5. The parking fee is calculated and confirmed by the computer.

　　6. The method of combining computer networks and charging software prevents illegal modification and unauthorized access to information.

　　7. The management computer and each charging computer can realize real-time communication, and the management computer has an external interface, and the network is extensible.

　　 8. The standard industrial control system structure is adopted, and the configuration of different systems can be organized according to the different requirements of users, which is convenient and flexible.

　　 9. Installation, debugging and maintenance are simple and convenient, easy to replace and overhaul.

　　10. The entire system has stable performance and reliable use.

　　 Principle of Intelligent Parking Management System

　　 The long-distance parking lot management system attaches the label that identifies the vehicle to the windshield glass of the car, encodes the car identification information, and calibrates the label to make it consistent with the system. When a car with a tag enters the reading area, the reading head emits a radio frequency signal to it, and part of the signal received by the tag adjustment is reflected back to the reader. The reader then reflects the identification code contained in the reflected signal to the qr code reader to read the code. The device decomposes the identification password from the signal, confirms the password according to the standard determined by the user, and transmits the password to the main computer or other data recording equipment.

　　 When the vehicle arrives at the exit, the system automatically recognizes the card number by reading the information of the RFID card and retrieves the corresponding vehicle record through the information in the internal database, so that the interface displays the user type, license plate number, vehicle photo, and other information. In order for employees to check and verify, once an illegal user appears, the system will generate an alarm prompt.

　　Intelligent parking lot management system composition

At present, it is mainly used for parking lots with fixed users as the main and temporary users as supplementary. It can be used in nested networks to form a powerful parking lot management system, which is mainly composed of UHF RFID remote card readers, UHF RFID remote Distance read-write antenna, UHF RFID tags, integrated barriers, entrance UHF RFID card issuing machine, exit toll machine, network remaining parking space display, network voice intercom, toll display, voice prompt, a vehicle dedicated network camera, It is composed of parking lot management software and guard box charging software.

　　The following is an introduction to the main parts of the system:

　　1. Entrance control part: integrated barriers, vehicle detectors, remote RFID read-write antennas, UHF RFID remote card readers, entrance UHF RFID card issuers, LED external display screens for remaining parking spaces.

　　2. Export control part: integrated barriers, vehicle detectors, long-distance RFID read-write antennas, UHF RFID long-distance card readers, and export toll collection machines.

　　3. Management center: computer host, parking lot management software, RFID desktop card issuer, etc.

　　4. Sentry box center: computer host, sentry box charging software, RFID desktop card issuer, network voice intercom, thermal piaoju printer.

　　 5. Image capture system: a dedicated network camera for parking lots.
