随着大规模集成电路和微电脑技术的迅猛发展,70年代末出现了微电脑红外线遥控系统,它不仅提高了整机的主要性能指标,还便于操作,且取消了进行操作所需的机械触点,使整机工作稳定,使用寿命延长。但由于红外遥控发射器使用频繁且易摔,所以极易出 With the rapid development of large-scale integrated circuits and micro-computer technology, the late 70s appeared micro-computer infrared remote control system, which not only improves the main performance indicators, but also easy to operate, and canceled the need for mechanical contacts, Make the machine work stable, prolong the service life. However, due to the frequent use of infrared remote control transmitter and easy to fall, so easy to go out
