本设计是依靠门禁微控制器为核心的器件，结合按键电路、LCD显示电路、报警指示电路、开锁机构、无线电模块电路，利用微控制器灵活的编程涉及和丰富的I/O端口，及其控制的准确性通过软件程序来控制整个系统实现电子门禁系统的基本功能。门禁系统，又称出入口门制系统。就是在何处放行哪些人，何时要发出警报，记忆出入饿过程，以达到安全的目的。-The design is to rely on micro-controller core, access control devices, combined with key circuit, LCD display circuit, the alarm indicating circuit, lock body, the radio module circuit, using micro-controller involved in programming flexibility and rich I/O ports, and control the accuracy of the software program to control the whole system to achieve the basic functions of electronic access control system. Access control system, also known as entrance door system of systems. Where and who is released, when to sound the alarm, the process of memory out of hunger, to achieve security.
