The infrared remote control cipher lock has become the property security essential device. The infrared remote control cipher lock design uses a single chip AT89C51, combined with the infrared emitter and the infrared receiver, in considering the economic applicable, the integration of SCM and infrared remote control technology, will be used for security lock further intelligence. This design includes commonly used digital tube display circuit, which can display the input digital code, and can modify the password .all of these make it more intelligent, humane.Keywords:microcomputer、AT89C51、infrared remote control、 single-chip、intelligent目录摘要………………………………………………………………………2Abstract…………………………………………………………………3第一章 绪论……………………………………………………………6设计思路………………………………………………………6设计的意义……………………………………………………6课题背景………………………………………………………6密码锁发展趋势和特点………………………………………7第二章 红外遥控系统…………………………………………………8红外通信原理…………………………………………………8红外线的基本知识……………………………………………9红外遥控系统结构……………………………………………10调制………………………………………………………10解码………………………………………………………10发射系统…………………………………………………11红外接收头HS0038 ……………………………………12红外编码格式…………………………………………………13密码锁的功能…………………………………………………14第三章 红外密码锁硬件设计…………………………………………16系统整体框图…………………
