From without, be difficult to judge B mark signal wire or C mark signal wire, when application, tend to easily take by mistake, and then change a netting twine, sometimes to take and repeatedly change ability correctly, sometimes, operating personnel do not notice that what take is the signal wire of which kind of standard, after in connection, display screen can not normally show, then, operating personnel will start debugging from control system, final discovery is netting twine mistake, like this, can waste a lot of time, in urgent situation, may have influence on user and use display screen, cause unnecessary loss.
At present, display screen manufacturer does not all have a kind of good method can distinguish the signal wire of various criterion, can only rely on people for making marks, warehouse stores classifiedly, still, once manual operation carelessness, just be easy to make mistake, can not fundamentally address this is that.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of signal wire proving installation is provided, can test fast LED display signal wire and belong to any class standard, by the classification of pilot lamp indicator signal line, efficiently solve in prior art that signal wire standard is inconsistent is difficult to distinguish, easily take by mistake the problem that affects work efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of signal wire proving installation, comprises testing cassete, power pack, described testing cassete comprise end face, bottom surface, above, below, side, the arranging below of the adjacent testing cassete of described power pack; Before described testing cassete, two signal input ports are set, described testing cassete inside arranges test circuit; Described test circuit is connected with power supply, two signal input ports respectively, and the inside of described power pack arranges power supply.
Described test circuit comprises 8 switches, 16 pilot lamp, described two signal input ports include 8 pins, be respectively first signal input port, secondary signal input port, between the positive pole of described power supply and each pin of first signal input port, all connect successively a switch and a pilot lamp, the pilot lamp of all connecting between each pin of described secondary signal input port and the negative pole of power supply.
Described switch is arranged at the end face of power pack, and described pilot lamp is arranged at the end face of testing cassete.
Described pilot lamp comprises two rows, is set to a row successively with the pilot lamp of first signal input port by port numbers, is set to second row successively with the pilot lamp of secondary signal input port by port numbers.
Described switch is corresponding one by one with the port numbers of signal input port, is set in turn in the end face of power pack.
Described first row pilot lamp is red light emitting diodes, and described second row pilot lamp is green LED.
Compared with prior art, the beneficial effects of the utility model are:
(1) this apparatus structure is simple, and simple operation, as long as signal wire two ends are inserted to the signal input port of this device, is opened switch, viewing lamp, gets final product judgment signal line standard, has saved the time, avoid taking by mistake signal wire, lost time, improved operating personnel's work efficiency.
(2) test circuit is simple, only needs resistance, light emitting diode, and external battery power supply, can realize the test of signal wire, safe and reliable, has saved cost.
(3) standard of the pilot lamp indicator signal line by different colours, very clear, short and sweet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
Wherein, being designated in figure: 1-testing cassete; 2-signal input port; 3-pilot lamp; 4-power pack; 5-switch.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is elaborated:
As shown in Figure 1 and Figure 2, a kind of signal wire proving installation, comprises testing cassete 1, power pack 4, described testing cassete 1 comprise end face, bottom surface, above, below, side, the arranging below of the adjacent testing cassete 1 of described power pack 4; Before described testing cassete 1, two signal input ports 2 are set, the inside of described testing cassete 1 arranges test circuit; Described test circuit is connected with power supply, two signal input ports 2 respectively, and the inside of described power pack 4 arranges power supply.
The battery of 1.5V for the power acquisition of the present embodiment.
