摘要

红外遥控技术的出现，不仅大大提高了劳动生产率，降低了成本，而且减轻

了人们的劳动强度，改善了劳动条件。红外线遥控器具有体积小、功耗低、功能强、成本低等特点从而成为了当今非常流行的一种控制方式

红外遥控器是一种利用红外遥控系统来控制被控对象的系统.整个系统由数字电路和模拟电路两个部分组成。发射部分包括键盘矩阵、编码调制、LED红外发送器；接收部分包括LED红外光发射、解调、解码电路。

通过对设计要求地认真分析和研究，拿出了几种可行方案，最终选定了一个最佳方案。该方案是采用先进的单片机技术实现遥控的主要手段。我们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。

Abstract

Infrared remote control technology, not only greatly improved labor productivity, reduced costs, and reduce the people's labor intensity and improve the working conditions. Infrared remote control has a small size, low power consumption, functionality, and low cost in order to become a very popular present-day control.

The infrared remote control is one kind of use infrared remote control system controls is controlled the object the department green overall system is composed by the digital circuit and the analogous circuit two parts. Launches partially including the keyboard matrix, the coded modulation, the LED infrared transmitter; Receives partially including the LED infrared light launch, the demodulation, decodes the electric circuit.

After analyzing and researching on the request of the design, we take several blue print and we selected the best one in the end. The project make use of advanced SCM to realize the remote control. Remote controller we designed can dominate 5 electrical source switches and adjust the brightness of one light.
