Many friends in the weak group have more problems with the access control system. The main reason is that the composition of the access control system involves a relatively wide area. Today, we have come to understand the topology of various access control systems.
First, the basic composition of TCP/IP access control system design based on fingerprint identification:
(1) Management Center: A PC connected to an access controller or network, connected to other access controllers or PCs via a LAN or WAN, to process and analyze information collected by the access controller, and send control commands, and For the corresponding software management.
(2) Access Control Management Software: The management workstation remotely monitors the working status of servers and access controllers through management software to implement various management functions.
(3) Access controller: used for front-end information collection, transmission and processing, and control the electronic locks and doorbell access control, the implementation of the processor to open the door, alarm, start the doorbell and other instructions and to provide communications multi-machine connection port.
(4) Electronic door lock: The implementing agency and key equipment of the access control system are used to control the physical channel.
(5) Power equipment: DC power is used as the operating power and door lock power of the entire access control system (usually internal power supply).
(6) Linkage equipment: It can link with all input and output nodes of the access controller to realize the linkage of large-scale systems such as anti-theft alarms and fire alarms. Generally, the relevant equipment is programmed in the access control management software.
(7) Communication equipment: including switch equipment, routers and MODEM, etc. to realize the network connection of the equipment.
