Zero power consumption standby television set and implementing method thereof

Abstract

The invention discloses a zero power consumption standby TV, including a remote controller, a TV switching power supply and other TV circuits connected to the TV switching power supply, wherein, the TV switching power supply is also connected with an AC-DC converting circuit and an energy storing circuit, and the TV switching power supply outputs an AC power to the two circuits, respectively; theoutput of the AC-DC converting circuit is connected to a relay controlling the power source switch, and the energy storing circuit is connected to the relay through a thyristor; the thyristor is alsoconnected to a photoinduction triggering circuit; the TV CPU is connected with an alternating-current standby control circuit through a AND gate circuit, the alternating-current standby control circuit is connected to the relay. The invention applies a method of instant optical triggering to control the continuous closing of the relay in the standby zero power consumption scheme, which has simpleduty circuit, and low static power consumption; the relay adopts a self-latching circuit, which can continuously close only by using less energy to instantly drive the relay, so as to realize the zero power consumption standby.

Description

【Technical field】 [0001] The invention relates to the technical field of televisions, in particular to a zero-power standby television and its implementation method. 【Background technique】 [0002] As energy issues have attracted more and more attention, the standby power consumption of household appliances, especially the standby power consumption of TVs, has begun to attract everyone's attention. The proportion of the standby power consumption of TVs in the total household energy consumption cannot be ignored. In addition, fires caused by televisions occur from time to time, and they often occur when there is no one on standby. Whether it is possible to achieve absolute zero power consumption in the standby state of the TV, completely disconnect the 220V mains, and realize energy saving and safety in the standby state of the TV is an urgent problem in the TV field. At present, in the field of standby power saving, the existing technology only reduces standby energy consum...

China Invention Patent No. 200410053286.6, its name is a method for zero-power standby of household appliances powered by supercapacitors. It is still on duty when it receives the power-on command, and its function is to turn on the power and then start the machine when it receives the power-on command. The on-duty circuit includes the remote control receiving circuit and the single-chip microcomputer that analyzes the remote control code. However, in the standby state, the relay and the triode that drives its action still consume a small amount of 220V. Energy consumption is not zero power consumption in the true sense, and the solution uses a supercapacitor with a capacity a thousand times larger than the electrolytic capacitor for standby power supply. When using manual power-on, once the manual power-on method is used, the power-off must also be done manually
