Access control system based on ZigBee

Abstract

The invention relates to an access control system, and concretely relates to an access control system based on ZigBee. The access control system comprises a gate inhibition controller, a ZigBee module (a terminal node), a ZigBee module (a router), a ZigBee module (a coordinator) and a monitor terminal. The gate inhibition controller is connected with the ZigBee module (the terminal node) through a serial port, the ZigBee module (the coordinator) is connected with the monitor terminal through the serial port, and the ZigBee module (the router) is connected with the ZigBee module (the terminal node) and the ZigBee module (the coordinator) through ZigBee wireless transmission network. The access control system based on ZigBee has the beneficial effect that the system can perform remote management and operation on the gate inhibition controller by two networks of the ZigBee wireless transmission network or GSM network; each gate inhibition controller can be independently operated, and can be operated through networking of the ZigBee wireless transmission network.

Description

technical field [0001] The invention relates to an access control system, in particular to a ZigBee-based access control system. Background technique [0002] With the development of communication network technology, access control systems are widely used in places such as living rooms, offices, and warehouses. The access control methods used in access control systems usually include access control cards, access control passwords, and fingerprint identification. RFID technology has been widely used in access control systems. Wide range of applications. On the one hand, the known access control system usually has a monitoring host for system management. The monitoring host is the core of system management. When the monitoring host breaks down, it will affect the normal use of the access control system. On the other hand, in the known access control system, a monitoring host is usually used to manage an access controller, and the connection between the monitoring host and the...

Problems solved by technology

On the one hand, the known access control system usually has a monitoring host for system management. The monitoring host is the core of system management. When the monitoring host breaks down, it will affect the normal use of the access control system.

On the other hand, in the known access control system, a monitoring host is usually used to manage an access controller, and the connection between the monitoring host and the system usually uses a serial port line or other bus, which is cumbersome for wiring, and the connection distance will also be limited. restrictions, and it is not convenient for future cascading and expansion of the system
