Abstract

I nfrared ray is close, a means of high-speed wireless communication, as a kind of close, indoor means of communication, infrared has incomparable advantage over radio.

System is introduced in this paper by using the infrared communication channel constitute the infrared wireless short-range equipment control system, can meet the needs of the wireless control. This article mainly expounds the working principle and implementation method of infrared communication, infrared wireless communication process, a detailed analysis of each module of the system design, the best scheme of this system are derived, successfully completed the design of the system. This system is divided into three modules: voice module, the infrared emission module, the infrared receiving module. Power supply module adopts the 7805 of 5 v power supply. mainly used in infrared emission module triode, LM386 will receive the signal voltage amplifier and power amplifier and infrared transmitting tube. Mainly used in infrared receiving module triode, LM386 will receive the signal voltage amplifier and power amplifier and infrared receiving tube. The function of system implementation is the use of infrared light-emitting tube as the transceiver devices and infrared receiving module, transmission distance is 2 meters.
