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其的突 出,传统的机械锁由于其构造的简单,被撬的事件也屡见不鲜,因此,人们在日常生活中越来越越离不开密码的使用。在人们对安全的重视和科技的发展的同时,许多电子智能锁〔指纹识别、IC卡辨认〕已相继问世,但这类产品是针对特定指纹或有效卡。另外,卡片式的IC卡易丢失和损坏,加上其成本较高,在一定程度上限制了这类产品的普与和推广。鉴于目前的技术水平和市场的接收程度,电子密码锁是这类电子防盗产品的主流。据51单片机之间的串行通信原理,这便于对密码信息的随机加密和保护。反应速度快、传输效率高、工作稳定可靠。测试结果表明,本系统各项功能已达到本设计的所有要求

Abstract
With the development of living standard, how to ensure guard against theft become a particular problem. Traditional machinery locks being pried-out is not a unusual events. Thus, people get more and more rely on the use of password. Many electronic technological locks <fingerprint identifier, IC identification> have appeared in succession. These machine is aim on special fingerprint or card. What’s more, the IC might get lose or destroyed easily with its high cost, which greatly limit the popularity of these machine in some aspect. For the standard of technology and marketplace reception, electronic password lock is popular during this electronic coded to the principle of serial communication between 51 single-chip microcomputer, this is easy to encrypt and protect the password information.
