Description

Voltage x current real-time monitoring system for EUT power supply
Technical field
This utility model relates to a kind of EUT Power Supply Monitoring technology, especially relates to a kind of voltage x current real-time monitoring system for EUT power supply.
Background technology
Existing major part interferance generator, such as lightning surge generator, remove pulse generator, drop generator etc., in the case of exchange EUT power supply or direct current EUT power supply, all the product after the most after tested can not be judged intuitively, external tool (such as circuit tester etc.) judgement must be measured, least a portion of power supply end can show supply voltage and electric current, but the existence due to decoupling network, the current value often measured and actual value have an outlet, and the miscellaneous function that this circuit also has is to can determine whether test product whether test failure, thus stop test.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of improve work efficiency, the voltage x current real-time monitoring system for EUT power supply that automaticity is high.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of voltage x current real-time monitoring system for EUT power supply, it is characterized in that, including concurrent interface, voltage sampling circuit, current sampling circuit, analog to digital conversion circuit, single-chip microcomputer, alarm and display, described concurrent interface input is connected with EUT power supply, described concurrent interface outfan is connected with voltage sampling circuit, current sampling circuit respectively, described voltage sampling circuit, current sampling circuit are connected with analog to digital conversion circuit respectively, and described single-chip microcomputer is connected with analog to digital conversion circuit, alarm and display respectively.
Described alarm is buzzer siren.
This system also includes the memorizer being connected with single-chip microcomputer.
This system also includes the communication module being connected with single-chip microcomputer.
Described communication module is Small Area Wireless Communication Networks or mobile communications network.
Described Small Area Wireless Communication Networks is bluetooth, ZIGBEE or radio frequency network.
Described mobile communications network is 2G, 3G or 4G network.
Compared with prior art, this utility model has the advantage that
1) automaticity is high, monitors EUT voltage and current in real time, can contrast the voltage x current value before and after test, makes further judgement, improves work efficiency and automaticity;
2) easy to operate, directly display digital quantity by display, and real time inspection data can substantially increase operation ease by remote terminal;
3) safety is high, by arranging alarm, simultaneously by locally stored and long-range storage double copies, substantially increases the safety of whole system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be wherein concurrent interface, 2 be voltage sampling circuit, 3 be current sampling circuit, 4 be analog to digital conversion circuit, 5 be single-chip microcomputer, 6 be buzzer siren, 7 for display module.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present utility model rather than whole embodiment.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, all should belong to the scope of this utility model protection.
As it is shown in figure 1, a kind of voltage x current real-time monitoring system for EUT power supply, including concurrent interface 1, voltage sampling circuit 2, current sampling circuit 3 and analog to digital conversion circuit 4, single-chip microcomputer 5, buzzer siren 6, display module 7.
Preferably, this system also includes the memorizer being connected with single-chip microcomputer, for storing the digital quantity that single-chip microcomputer receives.This system also includes the communication module being connected with single-chip microcomputer, for sending the digital quantity that single-chip microcomputer receives.
Preferably, described communication module is Small Area Wireless Communication Networks or mobile communications network.Described Small Area Wireless Communication Networks is bluetooth, ZIGBEE or radio frequency network.Described mobile communications network is 2G, 3G or 4G network.
When concurrent interface accesses EUT power supply, voltage collection circuit 2, current collection circuit 3 can gather output analog quantity automatically to analog to digital conversion circuit 4, then it is input to single-chip microcomputer 5 by analog to digital conversion circuit 4, single-chip microcomputer 5 is input to display module 7 after processing, monitoring display can go out voltage constantly, current value, when after each impact single-chip microcomputer can test after the voltage x current value that collects with test before value compare, if the value error of twice is more than 50%, then automatic decision is test abnormality, it is signaled to buzzer siren 6, alarm is made in buzzer siren 6 action.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; can readily occur in amendment or the replacement of various equivalence, these amendments or replacement all should be contained within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
