RFID application : Access control management

time2023/03/08

With the rapid increase of car ownership in cities, vehicle management has become a difficult problem. The core issue of effective vehicle management is how to identify vehicles. This paper introduces an access control system based on RFID technology. Applying RFID technology to the management of access control can effectively realize the fast and reliable identification of vehicles, and make the access control management in security achieve high efficiency and intelligence.

What is RFID Technology?

Radio Frequency Identification (RFID) technology is the specific application and development of automatic identification technology in radio technology. Its basic principle is to use radio frequency for non-contact two-way communication to achieve the purpose of identification and data exchange Therefore, it can realize multi-target recognition, moving target recognition and remote real-time monitoring and management. The communication distance can range from a few centimeters to tens of meters. Its main advantage is that it has strong adaptability to the environment and is less affected by rain, snow, hail, dust, etc. It can work all day, complete automatic identification, tracking and management non-contact, and can penetrate non-metallic objects for identification, with strong anti-interference ability.

System function

1. Remote identification

Because the recognition distance can reach 10m and the signal penetration ability of the system is strong, the owner's vehicle with card can enter and exit at a faster speed, while the driver does not have to stop, roll down the window, extend his arm to approach the card reader and other operations, greatly improving the traffic efficiency. The administrator shall provide a temporary ID card for temporary vehicle access.

 2. Double card confirmation

The system implements that the driver carries a card, which can be used for access control. A card is installed on the vehicle, and the system recognizes the signals of two cards at the same time before it can be released, achieving the double insurance function.

3. The system automatically records the time and place of passing

When the cardholder enters and exits, the computer will automatically record the pass record and cannot delete the record, which is convenient for the query, statistics and generation of various reports of the vehicles and personnel entering and leaving the community, thus eliminating errors, forgeries and cheating.

4. Automatic charging of temporary vehicles

After the temporary vehicle reads the card, the fee will be automatically calculated according to the admission time and the charging standard. The administrator will provide a free parking card for special vehicle access. The free parking card is specially set and cannot be counterfeited.RFID access control system applies radio frequency identification technology, which can realize that vehicles with valid electronic tags do not stop, which is convenient for passing and saves time, and improves the passing efficiency of intersections; More importantly, it can monitor the access of vehicles in the community or parking lot in real time, accurately verify the identity of vehicles and owners, maintain regional security, and make the security management of the community or parking lot more humanized, informationized, intelligent, and efficient.
