Embodiment Construction

[0035] Because the power socket of the existing control switch based on power measurement contains a shaping trigger, in fact, the power consumption of the main control device has a certain difference between the working state and the non-working state. The output signal after passing through the current detector and the rectification filter is used as the control source of the shaping flip-flop. Since the shaping flip-flop has a trigger threshold, for example, when the input signal is greater than a certain value, the shaped output signal will be generated; otherwise, the shaped output signal will not be generated. In the first case, when the main control device The power consumption is relatively small, the change difference of the power is very small, and the output signal after the rectification filter is not enough to trigger the shaping trigger to work, so the electronic switch cannot be turned on, so the controlled device plugged into the controlled socket is not The cu...

Abstract

This invention relates to a supply socket for a control switch based on the electric volume measurement including a primary control socket set, a controlled socket set, a current detector serial in a branch of the device supply to get the consumed volume of a device and a rectifying filter connected to the current detector and an electronic switch connected with the rectifying filter, the output of which is connected with the control end of the electronic switch and the switch contact point is serial in the supply branch of the controlled socket set. This invented supply switch and the supply indication lamp are set on a cable not in the supply socket.

Description

technical field [0001] The invention relates to a power socket, in particular to a power socket for controlling a switch based on electricity measurement. Background technique [0002] At present, the control basis of the control switch used for civilian power supply (such as 220 volts, 380 volts or 110 volts) to turn on and off the equipment is mostly controlled by manual and other external intervention control methods. However, for more than two As far as the equipment is concerned, the use of external intervention control methods will greatly increase the cost of the control equipment and inconvenient operation. Using the control relationship between the equipment to achieve closed-loop control between the equipment will help reduce the cost of equipment control and easy operation. For example, during the use of a computer, the computer and its peripherals are devices that have a master-controlled relationship. The TV set and peripherals also have a master-controlled re...
