基于单片机的电子密码锁系统设计

Design of electronic code lock system based on single chip microcomputer

电子密码锁是一种通过密码输入来控制电路或是芯片工作,从而控制机械开关的闭合。单片机具有超大规模集成电路技术,有极强的数据处理能力,I/O口多。文章设计的密码锁能防止多次试探密码,该密码锁对单片机的型号选择、硬件设计、软件流程图、单片机存储单元的分配等都进行了注释,且结构小,功能强。现在很多单位甚至家里的各个家用电器,还有保险箱都需要它。

Electronic code lock is a kind of control circuit or chip work through code input,so as to control the closure of mechanical switch.Single chip microcomputer has VLSI technology,strong data processing ability and many I/O ports.The password lock designed in this paper can prevent multiple attempts to test the password.The password lock annotates the model selection,hardware design,software flow chart and the distribution of MCU storage unit,and has small structure and strong function.Now many units and even all household appliances at home,as well as safes,need it.
