遥控技术是指实现对被控制目标的遥远测控。按控制指令传输过程来分，遥控可以分为有线遥控和无线遥控两大类，本文介绍的是无线遥控——红外遥控，多功能红外遥控器具有多功能自适应性，即对不同的家用电器如：电视、空调、并向、VCD等都能实现遥控功能。它具有两种工作状态：一种是学习状态，一种是控制状态。-The remote control technology refers to realization of the objectives of the remote controlled monitoring. According to control instructions to sub-transmission, wired remote control and remote control can be divided into two major categories of wireless remote control, this paper introduces a wireless remote control- infrared remote control, multi-function infrared remote control with multi-adaptive, that is, different household appliances such as: TV, air conditioning, to, VCD and so on can realize remote control. It has two kinds of work: one is to learn the state, one is to control the state.
