Automatic turn-off circuit system based on power line broadband carrier communication technology

Abstract

The invention discloses an automatic turn-off circuit system based on a power line broadband carrier communication technology. The automatic turn-off circuit system comprises a power supply main switch and a socket unit which are connected through a power line, and further comprises a power utilization monitoring unit and a power supply control unit;, the power supply control unit is connected between the power supply main switch and the socket unit, and the power utilization monitoring unit is connected with the socket and the power supply control unit; the power utilization monitoring unit is used for detecting the power utilization condition of the socket, and transmitting useless electric signals to the power supply control unit in a power line carrier communication mode when when thesocket is in a power-off state; the power supply control unit controls the power supply main switch and the socket unit to disconnect electric connection after receiving useless electric signals of all the power utilization monitoring units at the same time, and the power supply control unit can also receive external input to open the electric connection of the power supply main switch and the socket unit. When the system is applied, the power utilization condition of the socket can be monitored, the socket and the power main switch are disconnected when the socket is not powered, the effect of saving electric energy is achieved, and meanwhile potential safety hazards of power utilization are reduced.

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
