基于单片机的电器遥控器的设计

摘 要：本文详细介绍了电器遥控器的特点，结构和工作原理。红外遥控技术是一种利用红外线进行点对点通信的技术，它是把红外线作为载体的遥控方式。由于红外线的波长远小于无线电波的波长，因此在采用红外遥控方式时，不会干扰其他电器的正常工作，也不会影响临近的无线电设备。该方案采用模块化设计，主要分为两个模块：红外发射模块和红外接收模块。所设计的遥控器能控制5个电器的电源开关，并且可对一路电灯进行亮度的调节。该设计可以遥控多种家用电器，节省了能源，操作非常简单，可扩展性强，只要稍加改变，即可增加其他使用功能。

A Design about the Tele-controller Based on SCM

Abstract: This article introduced the electric appliance remote control characteristic in detail, the structure and the principle of work. The infrared remote control technology is one kind carries on the point-to-point communication using infrared the technology, It is takes infrared the carrier the remote control way. Due to the long-wave infrared wavelengths than radio waves, Therefore, in the manner of the use of infrared remote control, does not interfere with the normal operation of other electrical appliances, It also will not affect radio equipment nearby. Modular design of the program can be broadly divided into two modules: infrared transmitter and infrared receiver module. I designed a remote control that can be controlled by the five electrical power switch and lights on all the way to adjust brightness. The design can control a wide range of household electrical appliances, saving energy, a very simple operation, scalability, and as long as a little change can be used to increase other functions.
