1、学校代码:10410序号:050300本科毕业设计题目:车库门自动开闭控制系统设计学院:工学院姓名:兰云祥学号:20050263专业:电子信息工程年级:05级指导教师:赵进辉二0一0年五月30摘要车库门全自动门控装置,其特征在于设有置于车库内和车库外的主控制器以及安装在车辆内的密码标识器,主控制器由单片机、315M无线接收器、解码器、键盘、数码管和红外对管组成,密码标识器由无线发射器和编码器。PT2262与PT2272地址和数据状态一模一样,PT2262电源端平时断开,若快到了车库门则按下按钮通电,编码器PT2262将地址和数据通过无线发射模块发射,同时无线接
2、收器的输出端接解码器的输入端,解码器的输出端VT接单片机的P3.3,若数据完全正确则车库内的单片机启动电机开启车库门,同时红外对管感应次数计数,出车库门后门自动下降,也可以通过按钮屏蔽红外对管,实现手动放下车库门。之后取车时通过输入密码控制电机启动开门。关键词:电子密码锁;单片机;无线收发模块;PT2262/PT2272编解码芯片;红外对管;30AbstractThegaragedoorfull-automaticdoorcontrolequip,itscharacteristiclieinestablishtoplaceatthegarageinsidewi
