摘　　要：介绍了一种可编程无线电遥控多通道开关系统的设计方法,详细阐述了其组成结构和工作原理。该方法采用芯片组PT2262/2272进行编解码,并通过无线电遥控方式传送指令键码给单片机实现多通道控制。在发射系统中采用十进制至8421码编码器实现对开关按键编址,从而对受控电路进行选择控制;在接收控制系统中引入单片机,通过充分利用其软、硬件资源,为无线电遥控提供了合理、廉价的解决方案。A design method for programmable wireless remote control multi-channel switchsystem is introduced and the basic frame and operating principle of the system is discussed in detail.We choose a pair of encoder and decoder PT2262/2272 to encode and decode the instruction signaland carry the instruction code to siglechip to realize muti-channel control by use of wireless remotecontrol.10-line to 4-line BCD encoder is chosen to encode the switch keys in the transmitting systemto control the objects selectively. Applying singlechip in the receiving system, this method canmake the best of singlechip’s resource of software and hardware and provide a reasonable andcheap resolving project for wireless remote control.
