摘  要
 随着社会物质财富的日益增长,安全防盗已成为社会问题。而普通的机械锁已难以满足当前社会管理和防盗要求。为满足人们对锁的使用要求,增加其安全性, 用密码代替钥匙的密码锁应运而生，而且密码锁具有密码量大、使用方便等优点。
 为了解决目前锁的诸多不安全问题，本文提出简易数字密码锁的设计。本文主要包括以下的内容：提出了以AT89C51单片机为控制核心，短距离无线遥控技术和电子密码锁技术相结合的系统解决方案，给出了硬件设计电路和软件结构，详细叙述了系统的硬件线路的设计要点和结构以及软件的设计要点，同时给出了各个重要子程序的流程图。文中给出了详细的系统抗干扰措施。

Abstract
 With the increase of social material wealth, safety and guarding against theft have become social problems. Meanwhile, the ordinary mechanical locks are hard to meet the need of social management and   prevention of burglary. To meet people's requirement of the use of locks, to increase the security, the code locks which use password instead of key emerge as the times require. Moreover they have many advantages, for example they are more convenient and many password. 
 In order to resolving these insecurity problems of the lock, the design of the simple digital password lock is proposed in this article. The article principally includes next contents. The article describes a solution project in which the microcontroller AT89C51 is CPU and the remote technology is complex with the technology of electronic password lock.  The hardware structure and software design of system is explained. The article describes the pith of design and structure of hardware and software in detail and the flowchart of important subroutine is shown. The detailed methods of resistance to intrusions are shown.
