红外线遥控是目前使用最广泛的一种通信和遥控手段。由于红外线遥控装置具有体积小、功耗低、功能强、成本低等特点，因而，继彩电、录像机之后，在录音机、音响设备、空凋机以及玩具等其它小型电器装置上也纷纷采用红外线遥控。工业设备中，在高压、辐射、有毒气体、粉尘等环境下，采用红外线遥控不仅完全可靠而且能有效地隔离电气干扰。-Infrared remote control is the most widely used means of a communication and remote control. As the infrared remote control is small, low power consumption, strong function, low cost, and therefore, following the color TV, VCR, after the tape recorders, audio equipment, air withered machine and other small toys and other electrical devices have also used infrared remote control . Industrial equipment, high pressure, radiation, toxic gases, dust and other environments, using the infrared remote control is not only completely reliable and can effectively isolate the electrical interference.
