Problems solved by technology
[0002] The electrical equipment consumes energy in standby during the standby period, and the unsafe problem of "standby" electrical equipment is brought about because the power supply is not completely turned off.
[0003] In 2000, the International Energy Agency launched the "1W Plan" energy-saving initiative to electrical product manufacturers and sellers in its member countries. my country has also issued relevant energy-saving certification for standby energy consumption, but many electrical equipment still fail to achieve zero power consumption, Even 1W power consumption standby

Embodiment Construction
[0036] Such as figure 1 As shown, a standby automatic power-off switch device is composed of a switch control memory unit 100, a switch closing drive unit 200, a switch power supply unit 300, a button power supply unit 400, a dual-way isolated power supply unit 500, and a power-on detection unit 600 , a trigger pulse shaping unit 700, and a standby state judging unit 800.
[0037] The switch control memory unit 100 has an asynchronous setting input terminal, an asynchronous reset input terminal, an edge trigger pulse input terminal, and a switch control signal output terminal, which are used to realize the state control and memory of the switch; its function is that the output switch control signal is set When the position is set, the switch is closed; when the output switch control signal is reset, the switch is opened. The switch control signal is set and reset, which can be positive logic, setting corresponds to output high level, reset outputs low level; it can also be ne...

The standby automatic power-off switch device disclosed by the present invention includes components such as a switch, a button, a switch control memory unit, a DC regulated power supply, and a standby state discrimination unit. When an AC load is detected and the standby state is detected for a period of time, the switch can be automatically controlled to be disconnected. , cut off all power; when the switch is off, press the button to turn on the switch; when the switch is closed, press the button to turn off the switch. The switch is used in occasions where it is necessary to automatically cut off electrical appliances or equipment that have been in standby for a long time, and can be installed in the socket or connected in front of the electrical equipment.
Description
technical field [0001] The invention relates to a switch technology, in particular to a method and device for on-off control of a standby automatic power-off switch. Background technique [0002] The electrical equipment consumes energy in standby during the standby period, and the unsafe problem of "standby" electrical equipment is brought about because the power supply is not completely turned off. [0003] In 2000, the International Energy Agency launched the "1W Plan" energy-saving initiative to electrical product manufacturers and sellers in its member countries. my country has also issued relevant energy-saving certification for standby energy consumption, but many electrical equipment still fail to achieve zero power consumption, Even 1W power consumption standby. Contents of the invention [0004] The purpose of the present invention is to provide a switch device that can automatically cut off the power when the electric equipment is in the standby state without be...
