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。

-The infrared remote control is the most widely used form of communication and remote control means. Infrared remote control device with a small size, low power consumption, and low cost, therefore, following the color TV, VCR, tape recorders, audio equipment, air conditioning units, as well as toys and other small electrical devices have also infrared remote . Industrial equipment, high pressure, radiation, toxic gases, dust and other environmental infra-red remote control is not only completely reliable and effective isolation of electrical interference. 1
