Embodiment Construction

[0027] The source of the control signal of the control switch 1 in the present invention is based on the detection of the device by the single-chip microcomputer controller.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Referring first to Figure 2. The control switch 1 based on power measurement according to the present invention, that is, the part framed by the dotted line in Fig. 2, includes two main parts, one is a power detector for measuring whether the equipment that plays a main control role is working, so In order to obtain the power consumed by the device and judge whether it is working normally, the above-mentioned power detector needs to be connected in series in the power supply branch of the device, that is, one of the two power lines A and B connected to the device (power lead B in Figure 2) One end a1 and the other end a3 of the current detector in the control switch 1 are connected in ser...

Abstract

The invention relates to a control switch based on electric quantity measurement, comprising: electric quantity detector connected in series in equipment power supply branch to obtain equipment consumed electric quantity, electronic switch, and controller connected in series between the output end of the electric quantity detector and the control end of the electronic switch, which controls ON-OFF of the electronic switch according to the output of the electric quantity detector. And the invention also relates to an on-off control socket for the control switch, comprising: master control jack group, controlled jack group, and the control switch, where the equipment power supply branch is a master control jack branch, and the electronic switch is connected in series in the power supply branch of the controlled jack. And the circuit of the invention uses MCU as controller to digitize the detection results so as to make on-off control of the controlled socket group more accurate.

Description

technical field [0001] The invention relates to a control switch based on electricity measurement and a power socket using the control switch. 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, in the process of using a computer, the computer and its peripherals are devices that have a master-controlled relationship. Usually, the computer and the peripherals are connected to the po...
