基于单片机与串行通信的电子密码锁设计

Design of Electronic Code Lock Based on Single-Chip Microcomputer

基于AT89C52单片机,在异步串行通信总线上实现分组交换通信协议的电子密码锁的软硬件设计方法,经实验室小范围内测试,可实现按键输入、校验与报警等功能。该密码锁防嗅探,外围元件少,结构简洁,可单机或联网使用。

The paper introduced the electronic password-lock hardware and software design, which used AT 89C52 single-chip microcomputer and asynchronous serial communication bus. The electronic coded lock can achieve key input, validation, alarm, and other functions through small-scale laboratory testing, it anti-lock password sniffer, fewer external components, the structure is simple and can be used standalone or networked.
