1. Introduction
Access control system integrates IC card and lock. Then the IC card replace keys and works with PC to realize intelligent management which solves variety of shortcomings in the traditional locks. The access control system mainly includes three levels of equipments.
Firstly, it includes readers, electronic locks, exit buttons, etc.. They are used to receive input information which will be converted to electric signal and send to controller to complete open or close locks, etc..

Secondly, it includes access controller and others. The controller receives the related people information sent from the basic equipments. A single controller can form a simple access control system to manage one or several doors. Multiple controllers  connects with PC by communication network and composes a whole building access control.

Thirdly, the management PC installs the access control software which manages all controllers to send commands to them, set their setting and receive information from them to complete all information analysis and processing in the system.
