摘 要:可调遥控电源开关设计是基于红外发射及接收装置、单片机、双向晶闸管等器件构成的智能遥控电源开关,红外发射器模块采用RC震荡电路及其组件形成编码信号由红外二极管向外发送脉冲信息,红外接收器模块是由红外一体化接收头HS0038接收信号,完成对信号的解码等,得到相应的有效二进制编码然后向一级控制系统单片机传递,驱动相应硬件响应,设计中开关以双向晶闸管作为开关,能够使电源开关的操作简易,提高开关的安全性,可应用于具有高压可燃气体等特殊恶劣场合环境中。40543 毕业论文关键词:RC振荡电路;HS0038;STC89C52单片机;双向晶闸管
Adjustable Remote Power Switch Design
Abstract:Adjustable Remote Power Switch design is based on intelligent infrared transmitter and receiver, microcontroller, bidirectional thyristor device comprising a remote power switch, infrared transmitter module RC oscillator circuit and its components form a coded signal sent out by the infrared diode pulse information, IR receiver modules HS0038 integrated infrared receiver to receive signals, the completion of the signal amplification, detection, shaping, demodulation, to give the corresponding binary coded efficiently transmitted to the control system microcontroller to drive the corresponding hardware response, the design of the switch to two-way thyristor as a switch, the power switch can be easy to operate and improve the safety switch can be used with special occasions harsh environments like high-pressure flammable gas.
