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.

Description

technical field [0001] The invention relates to a device and a method for realizing remote control shutting down of an AC power supply. Background technique [0002] Existing TV sets generally have a remote control function, through which the remote control can realize the remote control operation of many functions such as conversion frequency, brightness, chroma, contrast, volume, mute, turn off, start (standby), etc., so it brings convenience to users. . [0003] But existing TV sets only provide the function of remote control standby and do not have the function of remote control to turn off the AC power supply. The total power supply of the machine is in the unloaded state, that is, the standby state. At this time, the switching power supply, remote control signal sensor and CPU of the TV set are in working condition together with their auxiliary circuits. Disadvantages such as economy and consumption of TV life. Contents of the invention [0004] The technical pro...
