摘　　要：产品更新迭代,现在人们使用的防盗手段,已经从传统的机械锁转变到电子密码锁。该设计提出一种基于数字电路芯片的电子密码锁设计方法,以数字芯片为核心设计逻辑电路,克服机械式密码锁密码量少、安全性差的缺点。该系统具有密码设置、按键提示音、记录输入密码错误次数、3次密码错误后触发报警和输入正确密码有指示灯等功能,具有成本低廉、功能实用的特点。Product update iteration,now people use anti-theft means,has changed from the traditional mechanical lock to the electronic password lock.In this design,an electronic password lock design method based on digital circuit chip is proposed,and the logic circuit is designed with digital chip as the core,which overcomes the shortcomings of mechanical password lock with less password and poor security.The system has the functions of password setting,key prompt tone,recording the number of password errors,triggering the alarm after three password errors,and inputting the correct password with indicator lights,with the characteristics of low cost and practical function.
