Load remote automatic control power supply device

Abstract

The invention discloses a load remote automatic control power supply device, which consists of a whole machine work power supply circuit, a remote startup instruction and shutoff instruction identification circuit, a power-up and power-down execution control circuit and a load continuous power-up and no-load automatic power-down identification circuit. Instructions are started by adopting the loop line direct current impedance principle of outward lines of a power control terminal and a load terminal, so as to finish a power transmission process; and an alternating current electromagnetic induction principle is adopted to identify and control a working state of a load and control the output of a power supply, so as to finish power output or power shut-off. According to the load remote automatic control power supply device, the function of power supply control is completed, the startup and the shutoff of the power control terminal are remotely controlled from the load terminal, and then, the functions that the power is automatically supplied when the load consumes power, the power is automatically shut off when the load does not consume power, and the power is also automatically shut off when a line is in interruption are achieved, so that the aims of improving the safety of power transmission and saving electric energy are reached.

Description

technical field [0001] The invention belongs to the technical field of electronic power control, and mainly relates to a load remote automatic control power supply device. Supply and shutdown for all power controls. Background technique [0002] As we all know, the working power of all electrical equipment, machines and various household appliances comes from the electric power source, and controlling the power source controls the power source of the electrical equipment. The current formal tools for controlling power supply are various "switches", "switches", "circuit breakers", "contactors" and so on. Turning on or off these "tools" just reaches the supply or cut off of control power. In actual work and production, there is a certain distance between the power "switch", "switch" and "contactor" and the actual electrical equipment. The general procedure is to first turn on the "switch" and "switch" of the main power supply. It has been sent to the input end of the electr...

Problems solved by technology

If the external line is disconnected due to some factors, the front end (switch knife) will not automatically cut off the power output, it must be cut off manually

Since it is impossible to know when the outside line is disconnected in time, and the current power supply "switch" and "switch knife" do not have the function of automatic cut-off, the existing power control form is not only inconvenient to control, but also has potential safety hazards and consumes electric energy. the disadvantages of
