基于多种通信方式的密码锁系统设计 摘要：针对传统机械锁的各种缺点和重要部门安全性的要求，提出一种基于红外遥控的密码锁设计方案，通过此方案设计的密码锁电路可以满足安全性要求，也能适应特殊环境的使用需求。本文介绍的一种由 8052 编程实现的控制电路，具有按键指示，控制开锁，控制报警，遥控开锁等功能。红外遥控密码锁的应用研究主要应用了红外线编码及解码技术，并通过单片机实现密码的设置、修改及识别功能。设计电路主要有红外线编码电路、红外线解码电路和键盘及显示电路组成。具有保密性强，灵活性高，适用范围广，特别适合家庭，车库，工厂等场所。关键词：红外线，密码锁，AT89C51 单片机AbstractEach kind of shortcoming which and Integral part security request locks in view of the traditional machinery ,proposed that one kind based on infrared remote control’s combination lock design proposal, may satisfy the secure request through this project design’s combination lock electric circuit, can also adapt the special environment use demand .This article introduced that one kind the control circuit which realizes by the 8052 programming, has the pressed key to instruct, control unblanking, control warning, functions and so on remote control unblanking, the infrared remote control combination lock’s applied research has mainly applied the infrared code and the decoding technology, and realizes the password establishment, the revision and the recognition function through the monolithic integrated circuit. The designa circuit mainly by the infrared encode circuit, the infrared decoding unblanking electric circuit and the keyboard and demonstration electricity the road is composed. Has secret, the flexibility is high , the applicable scope is broad, especially qualify family, garage, places and so on factory.Key word : infrared monolithic；combination lock；8052目录1 绪论 .............................................................
