How does the RFID security access control system work?
The principle of RFID is to transmit data by transmitting radio wave signals for non-contact data identification and access, and to achieve the functions of identity and item identification or information storage. The overall structure consists of two parts: the upper computer server management system and the lower computer card reader. The lower computer card reader mainly consists of six parts: power supply, main controller, liquid crystal display, card reading and writing module, antenna, and serial port communication.
The read-write module is mainly used to read RFID tag information. The LCD displays some prompt information and time and date. The main controller responds according to the identified information. The serial port is used for communication between the lower computer and the upper computer server.
The RFID access control system has no physical barriers. When people enter and exit the security door, the security door will automatically detect whether there are illegal tags in the channel. If an illegal tag is found, an alarm will be activated. It can not only facilitate the rapid passage of personnel, but also prevent the illegal passage of unauthorized personnel.
RFID access control system function introduction
1. It has multiple functions such as channel access control, security and anti-theft, and alarm
The RFID access control system has an anti-tailgating function, which can promptly identify unauthorized personnel who are trailing behind legal personnel and trying to enter the passage, and send out an audible and visual alarm in the monitoring center. Check later.
2. It is convenient for internal employees or residents to enter and exit, and to facilitate internal management
The RFID access control system does not need to swipe the card, which realizes the real fast pass. The RFID proximity card is safe and reliable, and has a long service life. The non-contact card reading method can reduce the mechanical wear of the card to zero. The access control system can only swipe the card from one direction to enter according to the corresponding direction of the swipe card, preventing internal personnel from releasing for outsiders, which can effectively prevent illegal personnel from entering from the other end while swiping the card at one end of the channel.
3. The access control management system improves the level of management
Using the RFID access control system, the management personnel can sit in front of the monitoring computer to understand the entry and exit of personnel, judge whether it is necessary to go to the scene for observation according to the real-time monitoring function of the computer, and at the same time browse, view, print or print information such as personnel entry and exit, alarm events, etc. archive.
