4.遥控系统电路工作原理分析与故障检修遥控彩电与普通彩电(非遥控)相比,最大的差别就是前者拥有先进的电脑控制的多功能遥控系统电路,而后者则无。遥控系统电路,它主要由红外遥控发射器、红外遥控接收器、微处理器及接口电路等四大部分电路组成,其中微处理器是整个遥控系统的控制中心。随着新型微处理器的不断出现,其功能将越来越丰富多彩。
4. Remote control system circuit analysis of the working principle and troubleshooting remote control color TV with ordinary TV (non-remote control), the biggest difference is that the former has advanced computer-controlled multi-function remote control system circuit, while the latter is not. Remote control system circuit, which is mainly composed of infrared remote control transmitter, infrared remote control receiver, microprocessor and interface circuits and other four major components of the circuit, in which the microprocessor is the control center of the entire remote control system. As new microprocessors continue to emerge, their capabilities will grow more colorful.
