4、es. When the application of infrared remote control becomes wilder and technologies of SCM become mature, the remote control system is the trend. The design was based on the needs of the market. Considering that infrared remote control is simple, easy to operate, low-cost, I use a special launching and receiving chip which depends on remote control. On the basis of this chip a system of intelligent infrared remote-control was designed for the fan. The
