摘要

随着汽车行业和社会经济的迅速发展，人类对于汽车的依赖性越来越强。当然，越来越多的私家车的出现，就需要涉及车库门的问题，针对车库门目前的发展现状，我们结合了AT89S51单片机和PT2262/PT2272的无线收发功能，在之前的普通车库门控制的基础上，又添加了红外发射、接收电路以及防盗报警电路等等。从而设计出一种智能车库门控制系统，此系统具有结构非常简单、可靠性高、价格低廉等诸多优点。

本篇智能车库门控制系统的门控装置，它的显著特征就在车库内和车库外设置有主控制器和在车辆内安装的密码标识器，主控制器是由单片机、解码器、315M 无线接收器以及红外对管组成，密码标识器又是由编码器及无线发射器组成。PT2272及PT2262的地址和数据状态是一模一样的，而PT2262的电源端平时是断开的，如果快到车库门的时候按下按钮通电，则编码器PT2262 就会将数据和地址发射出去借助于无线发射模块，与此同时，无线接收器输出端和解码器的输入端相连接，解码器输出端VT和单片机相接，如果数据完全准确那么车库中的单片机就会自动启动电机打开车库门，而红外对管此时感应次数计数，汽车离开车库门之后门就会自动下降。

ABSTRACT

With the rapid development of the automobile industry and the social economy, the dependence on the automobile is more and more strong. of course, the emergence of more and more private cars, you need to problems involving the garage door, in view of the current development status of the garage door, we combine the AT89S51 and PT2262 / PT2272 wireless transceiver function, prior to the ordinary garage door control based on, and add the infrared emitting and receiving circuit and the anti-theft alarm circuit and so on. To design a kind of intelligent garage door control system, the structure of this system is very simple, high

reliability, low price, and many other advantages.

The intelligent garage door control system of gating device. Its obvious characteristic is in the garage, and the garage set main controller and installed in the vehicle code identifier, the main controller is by the microcontroller, decoder, 315m wireless receiver and infrared to pipe and password identification device is composed of encoder and the wireless transmitter. PT2262 and PT2272 address and data state is exactly the same, and a power supply terminal of the PT2262 is usually broken, if approaching the garage door when press the button energized, encoder PT2262 will will address data and transmitted by wireless transmitting module. At the same time, wireless receiver output end and the decoder is connected to the input terminal, decoder output end of VT and MCU is connected, if the data is completely accurate so garage in SCM will automatically starts the motor open the garage door and infrared tube at this point counts of induction, the car left the garage door after door will automatically decrease.

Key words: SCM, infrared wireless, receiving module PT2272/PT2262
