Abstract
The invention is about a new kind of method that is used to come out the telecontrol of turning off the alternating-current main. It is to charge the capacitance using the alternating current that is from the starting up the electronic products of telecontrol through the rectifier tank. The working current makes the first relay turn off then to turn on the sub power that is to supply electricity to CPU. The CPU is used to turn off the second relay. The sub power and the CPU get in to the steady active state. The CPU can judge from the control signal of report controller. If there is a stand-by signal, it will turn off the third relay so to turn off the main power. If there is a cut-off signal, it will turn off the second relay and the third relay so to turn off the main power and the sub power. The invention also published a kind of device that is used to make the telecontrol of turning off the alternating-current main come true. The advantages of the invention are simple ness, safety, energy-saving and convenience.
