摘要
介绍了一个以AT89S52单片机为主要处理单元,配合存储电路、复位电路以及其它元器件实现门禁地址的分配及存储判定的门禁控制电路,该控制器通过对串口数据的处理,能实时对PC进行通信并通过实时代码验证各项控制器操作。
A simple hardware controller with the gate guard system is introduced. The controller takes the MCU (AT89S52) as the main processing unit. It coordinates the storage circuit and the reset circuit with all other primary devices, Moreover, it can communicate with PC in real time by processing the serial binarydata.
