Thanks to its convenient technical advantage is obvious, the wireless transmitting and receiving device has been widely used in communications, computer, automatic control, automatic measurement, remote control/remote sensing, instrumentation, medical equipment and household appliances and other fields. Household appliances single or multiple cable connection control, make its use is very inconvenient. So more and more home appliances begin to control wireless control technology is used to easy to use, through the adoption of wireless transmission technology makes appliance can not touch control. Control distance and height are big can meet the needs of the people live and work normally. So the wireless control technology has a high practical value. Household appliances power wireless control system design including transmitting and receiving radio, digital signal modulation and demodulation to transmit control information, the choice of MCU internal program design and system and so on several big aspects.
