The design of multi-channel infrared emission and receiving control system is realized with infrared communication. Transmitting circuit is mainly composed by the keyboard, encoder chip MC145026 and the infrared emitter;which receiving circuit is by the integrate reception, decoder chip MC14027 and the STC89C52RC microcontroller. This paper introduces the working principle of each unit circuit and its corresponding hardware principle diagram , installation and debugging through theoretical analysis and circuit, the single infrared emission system of 8 single infrared receiving device control .The systems has advantages such as strong anti-interference, reliable and accurate control, low failure rate, and simple debugging. It has high application value.
