Introduction to Library Security RFID Access Control Functions

Library security RFID access control is an open channel device installed at the entrance and exit of the library for book anti-theft alarm. When the security access control detects that a book tag carrying an unmodified anti-theft bit is approaching or passing by, the access control's alarm system will trigger and sound and light alarms will be issued. . From the perspective of product setting, the function of security RFID access control is mainly to detect whether the tag is allowed to be taken out, and it is a device mainly used for anti-theft purposes.
 

The body of the security RFID access control is composed of a large piece of acrylic. The antenna surrounds the body, making the tag reading speed faster, the reading rate higher, and the reading distance longer. The control host and read-write module are integrated at the bottom of the access control machine. . Security doors are divided into high frequency and ultra-high frequency according to the frequency band. No matter which frequency band, the structure of the entire access control machine is roughly the same, with the main door and the auxiliary door forming a channel. The control host is on the main door and is responsible for controlling the triggering of alarms. The anti-theft mode supports AFI, EAS, EAS and AFI, and supports active alarms and passive alarms. Supports multiple communication methods and can provide multiple interfaces for communication with library systems. There is a flow counter on the main door. Through the infrared function, the flow of people entering the museum on that day and the cumulative flow of people entering the museum can be recorded in real time. Data storage function can save alarm records for the background system to call out. The RFID access control detection function can perform interference detection, temperature detection and standing wave ratio detection. High frequency is greatly affected by the surrounding environment. Interference detection can facilitate on-site debugging of safety RFID access control to achieve the best state; if the temperature of the safety door electrical equipment is too high when it is running, it will affect the work. When the equipment performance is unstable, it can be detected whether it is caused by excessive temperature. ; Standing wave ratio detection is performed when reading tags is unstable. The access control detection function is conducive to troubleshooting and adjusting the properties of the equipment to achieve the best working condition and ensure the normal operation of the equipment.
 

At present, the library security RFID access control has optimized the auxiliary functions based on the basic functions. In order to better display the traffic data, a screen display can be installed on the body of the security RFID access control, and ambient lights can also be installed on the appearance. When used as a security RFID access control When in an abnormal state, different light displays will be emitted.
