Abstract
The utility model discloses a navigator test jig which comprises an equipment module, wherein the equipment module comprises a plurality of test equipment which is respectively connected with a navigator through corresponding detection interfaces. Due to the adoption of the navigator test jig, external equipment required for testing is reduced, and the wiring is simplified.
Description
Technical field
The utility model relates to a kind of measurement jig, particularly a kind of navigating instrument measurement jig.
Background technology
To automobile navigation instrument, the Function detection of particularly audio-visual navigation all-in-one can only be through the loaded down with trivial details single function of wiring test at present.Present test function is not very comprehensive, and the external unit that need use is also more, need use voltage table, camera or the like during such as test.The reason that produces these problems is that the testing apparatus of navigating instrument is numerous, and wiring is complicated during test; There is not the action of switching between the test function, wiring that can only be artificially.
The utility model content
The utility model purpose: to the problem and shortage that above-mentioned prior art exists, the purpose of the utility model provides a kind of navigating instrument measurement jig, and the external unit that need use when having reduced test has been simplified wiring.
Technical scheme: for realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is a kind of navigating instrument measurement jig; Comprise EM equipment module, said EM equipment module comprises a plurality of testing apparatuss, and said a plurality of testing apparatuss connect navigating instrument through the relevant detection interface respectively.
Also can comprise link control module; Said link control module comprises a plurality of CSs and the control interface that links to each other with each CS; Said control interface connects navigating instrument; Need the various functions of the navigating instrument of test through the CS switching, as: reverse image test, DVD test, day line traffic control test or the like.
In order to reduce the quantity of lead; Said CS and control interface can be located at PCBA (Printed Circuit Board+Assembly; That is to say that PCB (printed circuit board (PCB)) hollow plate process SMT (Surface Mounted Technology, surface mounting technology) goes up part, passes through DIP (Dual In-line Package again; Dual-in-line package) the whole processing procedure of plug-in unit can be described as wiring board) on.
Said testing apparatus can comprise display screen, loudspeaker, camera, voltage table, reometer and the time relay.
Beneficial effect: the basic function test of navigating instruments that the utility model measurement jig is more integrated; The external unit that need use when having reduced test; Simplified wiring; Also utilize wiring board and CS to reduce the testing procedure of navigating instrument, need not manual work, make test process more convenient according to the frequent wiring of different test events.The audio-visual navigation all-in-one of automobile functional test tool is under the situation that is not installed to the automobile real vehicle; Reach the test request of real vehicle environment; More exactly the function of the audio-visual navigation all-in-one of automobile is tested; Promote the quality of the audio-visual navigation all-in-one of automobile product, reduced the audio-visual navigation all-in-one of automobile and be installed to the probability that breaks down behind the automobile real vehicle; Also improve the efficient of producing simultaneously, make the ex factory pass rate of the audio-visual navigation all-in-one of automobile be improved.

Fig. 2 is an EM equipment module inner structure block diagram;
Fig. 3 is a link control module inner structure block diagram.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
As shown in Figure 1; The utility model measurement jig connects equipment under test navigating instrument and testing apparatus signal generator, oscillograph, DVD CD-ROM device and audio analyzer respectively; Because the volume of these testing apparatuss own is bigger; And to the navigating instrument of different model, need to use different testing apparatuss, so the utility model does not enter measurement jig inside with above-mentioned testing apparatus is integrated.
As shown in Figure 2; Be positioned at the inner EM equipment module of measurement jig and comprise following testing apparatus: display screen, camera, loudspeaker, voltage table, reometer and the time relay; These testing apparatuss connect navigating instrument through the relevant detection interface respectively, can detect the video output, voice output, voltage and current of navigating instrument etc.
As shown in Figure 3; Be positioned at the inner link control module of measurement jig and comprise a PCBA (wiring board), some CSs are located on this wiring board with the control interface that is attached thereto, and have so just saved the trouble that lead connects; Control interface is connected with navigating instrument again; Through CS control and the required test function of selection navigating instrument, comprising reverse image test, DVD test, day line traffic control test, audio track switching etc., because the test separately of each item test function palpus; Therefore through the closure control and the required test function of selection navigating instrument of CS, can effectively avoid prior art to need the trouble of artificial frequent plug lead.
Claims (4)
1. a navigating instrument measurement jig comprises EM equipment module, and said EM equipment module comprises a plurality of testing apparatuss, and said a plurality of testing apparatuss connect navigating instrument through the relevant detection interface respectively.
2. according to the said navigating instrument measurement jig of claim 1, it is characterized in that: also comprise link control module, said link control module comprises a plurality of CSs and the control interface that links to each other with each CS, and said control interface connects navigating instrument.
