Abstract：The system is based on 89C51 microcontroller as the core design of infrared transmission systems because of its high reliability and cost-effective in the intelligent home appliances, instrumentation and many other areas. It has been used in very widely domain. The SCM appliance shows the simplistic appearance, diversification of function, the development trend of superior performance in modern society. The infrared remote control apparatus which is easy to use, low power consumption and anti-jamming features, so its prospects are immeasurable.

　　　A centralized control infrared remote control program is designed base on the infrared wireless remote control technology. The core purpose is to design a wireless infrared remote control multiple transmit / receive system. The design of an infrared transmission of information as a carrier of controlled object can work many state short-range wireless control for home lights, it can be a device with many kind of synchronization control working state, or two kinds of equipment working with four state of simultaneous control.
