RFID technology in the intelligent parking lot management system program
chrispeng [ad_1]
With the advancement of science and technology and the development of human civilization, the application of intelligent parking lot management systems in residential quarters, large commercial buildings, and work units is becoming more and more common. People’s requirements for parking lot management and intelligence are getting higher and higher, and there is an urgent need for better, automated, and convenient management methods. Traditional parking lot management has various drawbacks such as high management cost, high labor intensity, low service efficiency, capital loss and serious vehicle theft. It cannot guarantee the income of investors and the safety of parked vehicles, which severely restricts the development of the parking industry. . The RFID intelligent system not only improves work efficiency, saves manpower and material resources, reduces operating costs, prevents employees from charging for personal gains and fraud, and the entire management system is safer and more reliable. Including driver identification, vehicle image comparison, parking space automatic guidance, vehicle entry and exit conditions, parking space tracking records and charging management, query and print vehicle information at any time.

2. System composition
3. The composition of the parking lot management system is mainly divided into two parts: hardware system and software system. The hardware system equipment is divided into the following 6 categories.
1) Entrance equipment: RFID equipment, ground sensing detectors, controller equipment, electric barriers, monitoring equipment;
2) Export equipment: RFID equipment, ground detectors, controller equipment, electric railings, lane cameras, cost display screens, sound and light alarm devices;
3) User charging terminal equipment: computer, video capture card, 485 communication card, charging receipt printer;
4) Data processing center equipment: data server, center card reader, backup power supply, communication modem.
5) Automatic parking guidance equipment: parking space information processing computer, parking space information detection system, parking guidance display screen, voice prompt equipment;
6) Parking lot monitoring equipment: surveillance cameras, video cards, displays, sound and light alarm devices;
4. Intelligent parking system function
- Vehicle access control function;
- Billing and charging functions;
- Vehicle identification function;
- Parking guidance function;
- Security monitoring function;
- Parking lot status information collection and processing functions;
- The function of communicating with the intelligent transportation system;
5. Advantages of RFID system for smart parking lot
1) High reliability, long service life, low maintenance cost: There is no mechanical contact between the RFID tag and the reader, which avoids various failures caused by contact reading. The normal service life is more than 10 years.
2) Convenient and fast operation: Using non-contact communication, the reader can complete the reading of tags within a range of 10cm-15cm or even more. The external bad influence is small.
3) Good encryption performance, safe and reliable: RFID tags have unique numbers when they leave the factory and cannot be changed. The communication between the tag and the reader also uses a two-way authentication mechanism.
4) Strong anti-interference and anti-collision: There is a fast anti-collision mechanism in RFID tags, which can prevent data interference between cards, so the terminal can process multiple tags at the same time.
5) Multiple authorization levels management: RFID tags can be set with multiple authorization levels, which increases the security of the entire system operation.
