1、 I 本本 科科 毕毕 业业 设设 计计 题目：题目：车库门自动开闭控制系统设计 II 摘摘 要要 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
2、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； III Abstract The garage door full-automatic door control equip, its characteristic lie in establish to place at the garage inside with flank of of lord controller and i
