embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
The object of this invention is to provide the short circuit test method of a kind of automatic identification technology for automobile-used pilot relay, by the automatic identification of a short circuit tester, can carry out short-circuit test to different automobile-used pilot relays, greatly improve production test efficiency and production environment, solved the existing issue of auto parts and components manufacturer production line.
Referring to Fig. 3-5, a kind of automatic identification technology is for the short circuit test method of automobile-used pilot relay.Have automatic identification learning function, power failure memory function, voltage sample uses 12 high-precision high-speed AD converters, and resolution is fast at a high speed, guarantees the accurate of test and tests the speed speed.
Learning manipulation is simple, as long as the product of needs test is put into from test fixture, clicks learn button, hummer ring 7 sound soon after learning success, and prompting learning success, next tests this type product as long as by testing button.If think to change other product of test midway, so the product of newly testing is put into fixture again relearning by learn button, simple and convenient.The product of the auto electronics relay that general short-circuit function tester will cover, but the function of each product is not identical with employing device, so just must demarcate the voltage parameter between each pin of this type product with an exemplar, allow instrument that these reference records are got off, and judge whether qualified standard as this product test.
The method of the voltage parameter between the each pin of judgment of learning is as follows:
(1) first pins of products to be added to voltage.We adopt the IO of single-chip microcomputer to control mouth to product making alive, and the feature of the IO mouth voltage of single-chip microcomputer is that output high level is 3.3V, and output low level is 0V.We make an IO mouth output HIGH voltage of single-chip microcomputer, another one IO mouth output LOW voltage, these two voltages are loaded into respectively on two different leading foots, if these two pin are because the reasons such as welding cause at internal short-circuit, the voltage that is equivalent to so these two IO mouths is directly connected, originally that IO mouth of output HIGH voltage can be forced to pull down to 0V; If there is electron device to be connected by pcb board, will certainly form so a loop between two pin, there is electric loop will produce a voltage drop, the size of voltage drop depends on type of device and the nominal parameters of device.
(2) such as product has 5 leading foots, be respectively A, B, C, D, E. so just can adopt above method to obtain voltage parameter.Specific as follows, first A pin is added to 0V, other four pin add 3.3V, after 20 milliseconds of wait voltage stabilizations of time delay, gather respectively B, C, D, the voltage of tetra-leading foots of E, and voltage data record is saved, as the foundation of test judgement.Again B pin is added to 0V, other four pin add 3.3V, after 20 milliseconds of wait voltage stabilizations of time delay, gather respectively A, C, and D, the voltage of tetra-leading foots of E, and voltage data record is saved.By that analogy, until the rear leading foot E of group is added to 0V, other four pin add 3.3V, and gather A after time delay, B, and C, after tetra-pin voltages of D, saves this group magnitude of voltage.
(3) the magnitude of voltage this being gathered between each pin for 5 times all saves, and as the whether qualified Rule of judgment of this type product, self study finishes like this.If replacing test products, need to test the product of different model, also only this new model product need be put into equipment, click learning key, the instrument automatically test parameters new work of laying equal stress on is the condition of test judgement.
The short circuit tester of the present embodiment has judgement parameter simultaneously, and test judge after reference record is got off and can be stored in the ROM of electrically-erasable, even power-off like this, these data also can not be lost, and facilitate storage for a long time, and tester theory diagram is shown in Fig. 4.
In addition, according to need of production, the parameter that can also simultaneously store a few cover different products by increasing storage unit, only needs to increase corresponding product and selects input switch just can directly test, as shown in Figure 5.
