Abstract:With the popularity of electrical appliance with standby function, the standby power consumption becomes a big waste. Standby power is produced when the plugs still is connecting to the power sources when machine stops normal work. Television, air-conditioning, water-machine, microwave pot can cause such standby power. As there is big difference between standby current and working current, working or standby mode can be judged by measuring the current flowing through appliances. STC single chip microcomputer is applied here to judge and control the working or standby mode. When detecting standby signal, microcomputer gives structure to relay switch to cut off the current, then standby power is eliminated so as to realize energy saving. Single chip machine can also restart appliance after receiving infrared signals. The significance and realization scheme are also discussed in this paper.
