现在,电视机、组合音响、录像机、影碟机、激光唱机到家用空调机等电子产品都实现了红外线遥控,给使用带来了方便。但是,由于遥控器的使用频率高,稍不注意就会损坏,如撞击、进水、滑落在地上等。 遥控器一般由一块集成电路,一个石英晶体、一只红外线发光二极管、电池及键盘等元器件组成。集成电路根据电路设计及遥控功能不同而有所不同。但其石英晶体大部分采用455kHz和480kHz两种,电源电压均为3伏。下面就如何检查判断遥控器故障,介绍几种最简单实用的方法。
Now, television sets, audio sets, video recorders, DVD players, CD players to home air conditioners and other electronic products have achieved infrared remote control, to bring convenience. However, due to the high frequency of use of the remote control, it may be damaged if it is not careful, such as impact, water ingress, slipping on the ground, and the like. Remote control usually consists of an integrated circuit, a quartz crystal, an infrared light-emitting diodes, batteries and keyboard components. Integrated circuit according to the circuit design and remote control function is different. However, most of its quartz crystal using 455kHz and 480kHz two, the power supply voltage is 3 volts. Here’s how to check to determine the remote control failure, describes several of the most simple and practical method.
