Technical field
The present invention relates to a kind of signal switch logic device, particularly relate to a kind of automobile instrument panel test board signal switch logic device, the signal that is used for Liuzhou five water chestnut P733 types and two kinds of automobile instrument panels of Chang'an antelope A736 type switches.
Background technology
Produce the company of automobile instrument panel, before product export, all will carry out all-round property testing, so that find product defects and in time solve existing problems it.An automobile instrument company often will produce polytype automobile instrument panel, if each panel board all disposes a cover test board, then needs very big input, also needs to take a large amount of productions space; The workman will be familiar with a plurality of test boards, causes training to be multiplied; A plurality of estrades also make the maintenance of equipment task increase the weight of.Current car replacement is regenerated frequent, and the panel board product is also updated, with the time tool advance.Only several years of a kind of life cycle of dial plate, this means that also original supporting for it test board can't use, and this is a kind of very big capital assets waste, must cause the remarkable rising of production cost.Test board is a very complex apparatus, relates to precision optical machinery processing, work such as mould location, electric wiring, Pneumatic System Design, and quite a few even if therefore single estrade drops into, the process-cycle is also very long.The way that solves is shared same test board, because the output pin signal of every kind of panel board has very big difference (seeing Fig. 1 and Fig. 2), must all be transformed into certain Unified Form to the out connector leg signal of every kind of panel board by the signal logic switching device shifter.The panel board of different model just can shared same test board like this, can simplify workman's operation like this, and production equipment is fully used, and production cost also can descend greatly.
Fig. 1, Fig. 2 are the inner structure and the output pin signal allocation figure of two kinds of different instrument dishes.Fig. 1 is the panel board for Liuzhou five water chestnut automobile accessories, works code is P733, as shown in Figure 1, for P733 type panel board, its A connector 1 signal is drawn as follows: A1 is the right turn lamp, A2 is negative for the panel board internal electric source, A3, A4, A5 is empty, A6 is an engine speed indicator, A7 is empty, A8 is the brake fault pilot lamp, A9 is empty, A10 is stand-by lamp I (+) end, A11 is stand-by lamp I (-) end, A12 is the air bag malfunction indicator lamp, A13 is a securing band controls alarm lamp, A14 is the anti-lock brake system trouble light, A15 is a fuel level gauge, A16 is the left steering lamp.B connector 2 signals are drawn as follows: B1 be panel board background illumination lamp, B2 for the panel board internal electric source is negative, B3 be water-thermometer signal, B4 be electronic fuel injection engine failed equipment pilot lamp, B5 be engine oil pressure indication and alarm lamp, B6, B7 for empty, B8 be charge in batteries indication and alarm lamp, B9 be stand-by lamp II (-), B10 be stand-by lamp III (+), B11 be preceding according to Driving beam telltale, B12 be the panel board internal electric source just, B13 is speed of a motor vehicle output signal.
Fig. 2 is the supporting panel board of Chang'an antelope, and works code is A736.As shown in Figure 2, for the A736 panel board, the A connector signal is drawn as follows: A1 be preceding according to Driving beam telltale (-), A2 be left steering lamp, A3 be right turn lamp, A4 for empty, A5 be charge in batteries indication and alarm lamp, A6 be the panel board internal electric source just, A7 be speed of a motor vehicle output signal, A8 be panel board background illumination lamp, A9, A10 for empty, A11 be that background illumination lamp negative terminal, A12, A13, A14, A15 are preceding according to Driving beam telltale (+) for empty, A16.The B connector signal is drawn as follows: B1 is that fuel level gauge, B2 are that engine oil pressure indication and alarm lamp, B3 are that securing band controls alarm lamp, B4 are that electronic fuel injection engine failed equipment pilot lamp, B5 are that parking brake is in the on-position pilot lamp, B6, B7 are that brake system trouble shooting/pilot lamp, B8 are that air bag malfunction indicator lamp, B9 are that anti-lock brake system trouble light, B10 are that water-thermometer signal, B12 are that water-thermometer/fuel level gauge ground wire, B13 are stand-by lamp I (-) end for empty, B11.
From as can be seen above, the output pin signal of these two kinds of panel boards has very big difference, for shared same test board, must all be transformed into certain canonical form to the out connector leg signal of two kinds of panel boards.
For the sake of simplicity, can select a panel board product as benchmark model such as P733 panel board, as reference signal, and the output pin signal of other panel board will switch to the signal of its inside such as left steering lamp on the reference pin of same signal definition (left steering lamp) by the logic switching device shifter its output pin.The left steering lamp of P733 is A16 in this example, and A736 is A2, therefore just A16, A2 need be switched to respectively on the C16 pin, that is to say, A16 links to each other with C16 when test P733 panel board, and A2 links to each other with C16 during test A736 panel board.All the other leg signal switching principles are identical.
