Description

Automatic power-supply switch
Technical field
This utility model relates to a kind of automatic power-supply switch.
Background technology
Traditional on-the-spot supply line electrical network is unstable, 380VAC powers it is possible that the situation of phase shortage, make the electrical equipment cannot be properly functioning, it is unexpected that power-off also can cause the damage of electrical equipment, so needing two-way power supply to power, generally wherein a road power supply is main power source, and another road power supply is stand-by power supply, and two-way power supply is standby each other.After main power source is because of fault dead electricity, automatically switches to stand-by power supply and power.And after mains power failure is got rid of, it is necessary to artificially cut off stand-by power supply, make power supply be switched to main power source by stand-by power supply, operator's ability to work be there are certain requirements by this process, and there is the possibility of maloperation, it is possible to cause power supply handoff failure, cause device supplying power for outside to interrupt.
Accordingly, it is desirable to provide a kind of new technical scheme solves the problems referred to above.
Utility model content
This utility model technical issues that need to address are to provide the automatic power-supply switch of a kind of stable work in work.
For solving technical problem of the present utility model, the technical solution adopted in the utility model is:
Automatic power-supply switch, it includes power supply handover module, voltage sample amplification circuit module, voltage configuration switch, comparison circuit module and single chip control module, described voltage sample amplification circuit module includes main power source amplifier circuit module and stand-by power supply amplifier circuit module, voltage sample amplification circuit module is to main power source, the AC signal of stand-by power supply output is sampled, signal after sampling is delivered to voltage configuration switch, described voltage configuration switch is connected with comparison circuit module input, described comparison circuit module outfan connects single chip control module, described single chip control module includes control signal drive circuit, control signal latch cicuit and single-chip microcomputer, described control signal drive circuit is connected with single-chip microcomputer by control signal latch cicuit, described single chip control module output control signal, described power supply handover module receives the control of control signal, by the feedback of status of two-way power supply to single chip control module, described power supply handover module connects control switch, power supply is exported by described power supply handover module.
In technique scheme, described single-chip microcomputer is also connected with communication module.
The beneficial effects of the utility model: automatic power-supply switch of the present utility model, when main power source breaks down, automatically power supply can be switched to stand-by power supply by main power source, and when main power source recovers normal, it is possible to automatically power supply is switched to main power source by stand-by power supply.
