本文介绍了红外多路遥控系统。红外多路遥控系统可实现16路的红外开关控制。以码分制多通道红外遥控为设计的基本思路。通过键盘及代码生成电路、编码、脉冲调制振荡和红外发射构成红外发射电路。通过红外接收，解码以及由单片机控制的医码控制电路组成红外接收电路。-The passage has introduced the nfrared multichannel system of remote control. The infrared multichannel system of remote control can realize the infrared switch control of 16 roads. With yard divide into system the basic train of thought with much passageway infrared remote control of design. Through keyboard and code generation circuit, coding and pulse modulation vibration with infrared project to form infrared project circuit. Pass infrared take over , decode as well as the medical yard control circuit composition that controled by single flat machine are infrared to take over circuit.
