摘要
介绍一种四路无线电遥控开关的设计方法,详细阐述电路组成结构和工作原理。该方法采用芯片组PT2262/2272进行编解码,PT2262与无线发射模块HS101连接构成遥控发射系统,PT2272与无线接收模块HS201连接构成接收系统。该系统通过发射接收无线电波实现开关的无线遥控。其装置具有体积小、功耗低、成本低,遥控距离可达100 m以上。
This paper introduces a design method for four- channel wireless remote control switch system,and discusses the basic frame and operating principle of the system in detail. This method applies a pair of encoder and decoder PT2262/2272 to encode and decode the instruction signal,PT2262 and the wireless transmitting module HS101 constitutes the transmitting system, PT2272 and the wireless receiving module HS201 constitute the receiving system. The system carries the radio wave to realize wireless remote control. The device have small volume, low power waste and low cost, and the remote distance exceed 100 meter.
