【摘要】 介绍一种新型可编程无线电遥控多通道开关系统的设计与实现方法,详细阐述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AVR单片机AT90S2313,实现了多通道控制.在发射电路中采用十进制至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,为无线电遥控提供合理、廉价的解决方案,使系统具有控制灵活、扩展方便、可实现多通道多功能控制等特点.更多还原

【Abstract】 A design method for a programmable wireless remote control multi-channel switch system is introduced and the basic frame and operating principles of the system is discussed in detail.We chose an encoder PT2262/2272 to encode and decode the instruction signals to carry the instruction code to an AVR microchip AT90S2313 to realize multi-channel control by use of a wireless remote control unit.A 10-line to 4-1 line BCD encoder was chosen to encode the switch keys in the transmitting system to control the objects selectively.Applying a microchip in the receiving system,this method can make the best of the microchip’s resources for both software and hardware to provide both a reasonable and cheap project for analyzing a wireless remote control.更多还原
