本设计主要应用了AT89C2051单片机作为核心，综合应用了单片机中断系统、定时器、计数器等知识，应用红外光的优点。遥控操作的不同，遥控发射器通过对红外光发射频率的控制来区别不同的操作。遥控接收器通过对红外光接收频率的识别，判断出控制操作，来完成整个红外遥控发射、接收过程。

其优点硬件电路简单，软件功能完善，性价比较高等特点，具有一定的使用和参考价值。

-The design of the main applications of the AT89C2051 microcontroller as the core, comprehensive application of the SCM interrupt system, timers, counters and other knowledge, the advantages of using infrared light. Remote operation of different remote control transmitter via infrared light emission frequency of the control to distinguish between different operations. Through the infrared remote control receiver optical receiver frequency identification, to determine the control operation, to complete the infrared remote control transmitter and receiver process.

The advantage the hardware circuit is simple, the software functional, high cost, etc., with some use and reference.
