Abstract

Today, Infrared remote control technology has been applied to various aspects of our life and production. It is used not only in the high-end technology, such as aerospace, but also in all kinds of remote controls in our daily life. Therefore, the infrared remote control simulation system based on single chip microcomputer is designed. The remote control simulation system is mainly designed for household appliances requiring remote control. The design's overall task is that LED lights are switched on by the remote signal light. The direction from the LED light switched on by the remote signal light determines the on-off of the light relay switch, then determines the on-off of the external circuit. The design mainly consists of infrared emission and receiving end, STC89C51 microcontroller pin connection, LED display parts and the designing of relay hardware, then it will be tested and put into operation. It simulates how the relay switch and LED lights work according to the remote signal, and connects the LED display to the on-off of the external circuit.
