Remote radio frequency identification (RFID) technology is the most advanced fourth generation automatic identification technology in the world. It has just started to rise and has been rapidly promoted and applied in recent years. It has the characteristics of long recognition distance, high recognition accuracy, fast recognition speed, strong anti-interference ability, long service life, and can penetrate non-metallic materials, and has a wide range of applications.

RFID intelligent parking lot management system not only retains all the functions of the traditional parking lot management system, but also improves the management media based on the original charging 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 these information in the database together with the unique correspondence of the user card. RFID vehicle management When the vehicle leaves the parking lot, it can only be released after the user card, license plate number or vehicle image and other relevant indicators are matched.

1. Performance characteristics are as follows:

1.1 Radio frequency identification technology and computer control are adopted, with high degree of automation and accurate control.

1.2 The remote intelligent identification label technology is adopted with good anti-counterfeiting performance. A parked vehicle has a unique A tag card with a serial number, which cannot be changed. Multiple encryption technology, unique identification, can not be copied. And only the system is approved.

1.3 The contactless smart tag card has no mechanical contact action, long-distance inductive communication and directionality when it is used. The card can be read within the remote reading range of the reader and the card can be read while the vehicle is not stopped, which is convenient for users to use.

1.4 The barrier gate will automatically rise and fall according to the traffic conditions of vehicles, and has the function of preventing vehicles from crashing.

1.5 Parking charges shall be counted and confirmed by computer.

1.6 The combination of computer network and charging software has prevented illegal modification and unauthorized access to data.

1.7 The management computer and each toll computer can realize real-time communication, and the management computer has external interface and strong network scalability.

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

1.9 Installation, commissioning and maintenance are simple and convenient, easy to replace and repair.1.10 The whole system has stable performance and reliable use.

2. Principle of intelligent parking lot management system

The remote parking lot management system is to attach the label identifying the vehicle to the windshield of the vehicle, code the vehicle identification information, and calibrate the label to make it consistent with the system. When a car with a tag enters the reading area, the reader emits radio frequency signals to it, and part of the signals received by the tag adjustment are reflected back to the reader. The reader then reflects the identification code contained in the reflected signal to the code reader, which decomposes the identification code from the signal, confirms the code according to the standards determined by the user, and transmits the code to the main computer or other data recording equipment.

When the vehicle arrives at the exit, the system automatically identifies the card number by reading the information of the RFID card, and finds the corresponding vehicle record through the information retrieval in the internal database, so that the interface displays the user type, license plate number, vehicle photo and other information. The system will give an alarm prompt in case of illegal users.

Yanzeo is a High Performance UHF integrated reader for long range operation. Compact Reader with integrated 9dBi circular polarized UHF Far Field antenna,.Based on proprietary efficient digital signal processing algorithm,the reader is capable of up to 10m Read Range and 3m Write Range.
