摘要
随着人们生活水平的提高,如何实现家庭防盗这一问题也变得尤为突出。传统的机械锁由于其构造简单,被撬的事件屡见不鲜。电子锁由于其保密性高,使用灵活性好,安全系数高,受到了广大用户的青睐。本设计以AT89S51单片机为核心器件,结合按键电路、LED数码管显示电路、存储电路、报警指示电路和开锁机构,利用单片机灵活的编程设计和丰富的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密码锁的基本功能。该锁能实现密码的输入、清除、显示,实现密码正确开锁,超位报警,系统设定初始密码的功能。设计成本较低,具有一定的实用价值。
With the improvement of people＇s living standards, they have to face the problem of their doors＇ security. Because of the simple structure of traditional mechanical lock, it could be broken frequently. Because of the electronic lock＇s high secrecy, good flexibility and high safety factor, the majority of pro-users hke to use it. It uses AT89S51 microcontroller as the core device, combined with key circuits, LED digital display circuit, memory circuits, alarm indicating circuit and lock body. It uses a flexible programming microcontroller, the rich I/O ports, and control accuracy by the adopted software program to control the whole system to achieve the basic functions of electronic locks. It can achieve the password＇s input, remove, display and achieve correct unlock using the password.It can also achieve the super digital alarm and the system function to set the initial password. The Design of electronic lock has a low cost and some practical value.
