Abstract
The invention discloses a power supply system of an industrial personal computer, which comprises a mains power grid. The mains power grid is connected with the industrial personal computer. The power supply system also comprises a standby power supply module, an MCU (micro control unit) and a current detection module, and the current detection module is connected between the mains power grid and the industrial personal computer and is used for detecting current signals and transmitting the current signals to the MCU; and the MCU is connected with the standby power supply module and is used for controlling communication of the standby power supply module and the industrial personal computer for supply of power to the industrial personal computer when no current signals are detected by the current detection module. By adopting the power supply system, uninterrupted power supply can be realized for the industrial personal computer, and the production stability can be ensured.
Description
Technical field
The invention belongs to the electronics industrial control field, particularly the electric power system of industrial computer.
Background technology
Industrial computer all is directly to adopt mains-supplied in the course of the work at present, for guaranteeing reliable, the normal operation of industrial computer; Must be to its uninterrupted power supply, however utility grid can be cut off the power supply because of uncertain factor; Cause industrial computer to work, influence production process.
Therefore, the inventor attempts to provide a kind of special uninterruptible power system to industrial computer, and this case produces thus.
Summary of the invention
Main purpose of the present invention is to provide a kind of industrial computer electric power system, and it can realize the uninterrupted power supply to industrial computer, guarantees production stability.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of industrial computer electric power system comprises utility grid, and utility grid is connected with industrial computer; Also comprise stand-by power supply module, MCU and current detection module, said current detection module is connected between utility grid and the industrial computer, the having or not and send into MCU of sensed current signal; MCU connects the stand-by power supply module, and detects no signal current time control preparation at current detection module and be communicated with industrial computer with supply module, is that industrial computer is supplied power.
Above-mentioned stand-by power supply module comprises stand-by power supply and switch, and said switch is connected between stand-by power supply and the industrial computer; MCU connects switch, and according to the break-make that has or not control switch of current signal.
After adopting such scheme, the present invention is through increasing the stand-by power supply module, and can break down in utility grid is communicated with industrial computer in the time of can not supplying power, and for industrial computer provides Emergency Power, realizes the electricly uninterrupted of industrial computer, guarantees the continuity and the stability of producing.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Embodiment
Below will combine accompanying drawing, structure of the present invention and beneficial effect will be elaborated.
As shown in Figure 1, the present invention provides a kind of industrial computer electric power system, comprises utility grid, and utility grid is connected with industrial computer, and for industrial computer provides power supply, this is an existing structure, repeats no more.
Improvement of the present invention is: also comprise stand-by power supply module, MCU and current detection module, said current detection module is connected between utility grid and the industrial computer, the having or not and send into MCU of sensed current signal; The output signal of MCU received current detection module, and according to the action of testing result control stand-by power supply module.
The stand-by power supply module comprises stand-by power supply and switch, and said switch is connected between stand-by power supply and the industrial computer; And the break-make of switch receives the control of MCU, and when the utility grid operate as normal, current detection module detects current signal, and this moment, the MCU control switch broke off, the power work that this moment, industrial computer utilized utility grid to provide; And when utility grid broke down, current detection module detected less than current signal, and this moment, MCU judged that utility grid breaks down, and is can control switch closed, is the industrial computer power supply by stand-by power supply, and that guarantees to produce carries out smoothly, reduces failure cost.
Above embodiment is merely explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of on the technical scheme basis, being done all falls within the protection range of the present invention.
