Through high frequency generator and the cooperation of investigation between the terminal, can detect rapidly and know the supply meter and connect the condition, avoid taking place the ammeter phenomenon of visiting one house after another, promote the power supply service quality, improve the power consumption both sides relation that supplies.
Description
Technical field
This utility model relates to a kind of supply line examination device, is especially a kind of ammeter and visits one house after another investigation instrument, belongs to field of electrical equipment.
Background technology
Along with the continuous enforcement of town and country power supply network upgrading project, the mistake caused due to wiring when installing in power engineering implementation process or install rear registration error, cause ammeter problem of visiting one house after another again and again to occur, cause client's mistake to pay the electricity charge.At present, ammeter is visited one house after another becomes a great universal phenomenon, directly affects power supply quality and for the bipartite relation of electricity consumption, have impact on normal for electricity consumption.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, it is provided that a kind of scene is investigated rapidly the ammeter whether electric supply meter visit one house after another and visited one house after another investigation instrument, to prevent ammeter from visiting one house after another the generation of problem.
In order to solve above-mentioned technical problem, the ammeter that this utility model provides is visited one house after another investigation instrument, including the high frequency generator being disposed in the interior and the investigation terminal connecting electric supply meter, described high frequency generator is used for producing pulse current, described investigation terminal is for detecting the pulse current that analysis of high frequency generator sends, and is finally confirmed whether that generation is visited one house after another behavior；
Described investigation terminal includes split-core type meter interface, current acquisition module, A/D modular converter, DSP processing module, display module and power module, described split-core type meter interface connects current acquisition module, current acquisition module connects A/D modular converter, A/D modular converter connects DSP processing module, DSP processing module connects display module, and described power module is for powering to current acquisition module, A/D modular converter, DSP processing module and display module.
Operation principle of the present utility model is: send pulse current by high frequency generator in the family of user, make user family produces in electric lines of force pulse current, if the investigation terminal being now connected on electric supply meter end can measure this pulsed current signal, this use table relationship match in every family is described；Failing to measure this pulsed current signal, then illustrate that the ammeter of this user is visited one house after another.
The beneficial effects of the utility model are: (1), by high frequency generator and investigation terminal between cooperation, understanding electric supply meter connection can be detected rapidly, avoid occurring ammeter to visit one house after another phenomenon, promote power supply quality, improve for electricity consumption both sides' relation；(2), this utility model simple in construction, it is simple to carry, uses easy to operate.
Accompanying drawing explanation
Fig. 1 be this utility model ammeter visit one house after another investigation instrument duty connection diagram；
Fig. 2 is that this utility model investigates terminal structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
The investigation instrument as it is shown in figure 1, ammeter of the present utility model is visited one house after another, including high frequency generator 1 and investigation terminal 2.Wherein, high frequency generator 1 is connected on user's indoor socket, sends the pulse current of high frequency for the supply line in user family.Investigation terminal 2 connects in electric supply meter wiring by split-core type meter, for identifying, confirming the pulse current that high frequency generator 1 sends.
As in figure 2 it is shown, investigation terminal 2 includes split-core type meter interface, acquisition module, A/D modular converter, DSP processing module, display module and power module.
Split-core type meter interface is connected with acquisition module, realizes the connection between ammeter and investigation terminal for inserting split-core type meter.
Acquisition module connects A/D modular converter, for acquisition pulse electric current and be sent to A/D modular converter.
A/D modular converter connects DSP processing module, and the simulating impulse current signal that acquisition module is collected by A/D modular converter is converted into digit pulse current signal, is sent to DSP processing module.
DSP processing module connects display module, after digit pulse current signal is processed by DSP processing module, detection analysis result is shown by display module, makes operator grasp testing result in time.
Power module, for powering to acquisition module, A/D modular converter, DSP processing module and display module, is investigated in the technical program in terminal and is used lithium battery power supply.
During use, first high frequency generator 1 is accessed on the indoor arbitrary socket of user；By split-core type meter, investigation terminal 2 is connected with the ammeter wiring of this user, opens investigation terminal 2 power supply；Open high frequency generator 1 and send pulse current；Investigation terminal 2 such as detects that high frequency generator 1 sends pulse current, then this use table relationship match in every family is described, if can't detect, then illustrates not mate, coherence check process to be carried out；After detection terminates, extract high frequency generator 1, close investigation terminal 2, remove split-core type meter.
Above-mentioned detailed description of the invention is preferred embodiment of the present utility model; this utility model can not be defined; other any change made without departing from the technical solution of the utility model or the substitute mode of other equivalence, within being included in protection domain of the present utility model.
