An automatic shutdown circuit system based on power line broadband carrier communication technology

Abstract

The invention discloses an automatic shutdown circuit system based on power line broadband carrier communication technology, which includes a main power switch and a socket unit connected through a power line, and also includes a power consumption monitoring unit and a power supply control unit, and the power supply control unit is connected to the main power switch Between the socket unit and the socket unit, the power consumption monitoring unit is connected to the socket and the power supply control unit respectively; The power supply control unit controls the main power switch and the socket unit to disconnect the electrical connection after receiving the useless electric signals of all power consumption monitoring units at the same time, and the power supply control unit can also accept external input to turn on the main power switch and the socket unit. electrical connection. When the invention is applied, it can monitor the power consumption of the socket, and disconnect the socket from the main power switch when the socket is not in use, thereby achieving the effect of saving electric energy and reducing hidden dangers of electric safety.

Description

technical field [0001] The invention relates to the field of automatic circuit systems, in particular to an automatic shutdown circuit system based on power line broadband carrier communication technology. Background technique [0002] Existing household circuit system is usually made up of incoming power line, watt-hour meter, main power switch, socket and power line etc., and electrical equipment inserts socket to connect power line through plug or patch panel, thus gets electricity to work. Existing electrical equipment is usually equipped with non-mechanical switches and / or mechanical switches such as tact switches and remote switches to control the electrical equipment on and off, so as to improve the convenience of using the electrical equipment. In the actual process of using electricity, due to human neglect and avoiding frequent plugging and unplugging of the plug to damage the socket and other reasons, users often only turn off the touch switch and remote control s...

AI Technical Summary

Problems solved by technology

[0003] For the situation that the electrical equipment has been turned off but the mechanical switch is not closed, and the plug is still inserted into the socket, the electrical equipment is still consuming electricity. Although the electrical equipment consumes less power at this time, generally between several watts and more than ten watts, but In the long run, the power consumption is still quite large; for the situation where the mechanical switch is turned off but the plug is still inserted into the socket, although the electrical equipment no longer consumes power, the circuit system has greater safety due to quality problems or aging of the plug and power strip. Hidden danger

Although some circuit systems in the prior art are connected to electrical equipment through controllable sockets, and the power supply of the equipment (including plugs and power strips) can be disconnected by closing the controllable sockets, the closing of the controllable sockets still requires manual control. It is impossible to avoid human neglect
