Description
Technical field
The utility model relates to a kind of electrical performance test system of spininess connector, refers in particular to a kind of spininess connector electrical performance test system based on the NI data acquisition equipment.The utility model is widely used in requiring to detect the every field of spininess connector electric property, especially is applicable to large enterprise to the test of batch spininess connector electric property, and simple to operation, dirigibility and versatility are strong.
Background technology
At present, require more and more highlyer with the electric property of the connector of extraneous communication in the equipment such as communication, medical treatment, test, increasing equipment needs the short open loop state between the test connector spininess.
Yet at present spininess connector electric performance test equipment is mainly contained open circuit and short-circuit test.When the electric property of test between spininess or test whether short circuit, or whether test open a way, weak point, open loop state between can not the arbitrary disposition spininess.If connector device is fitted on the circuit board, then short circuit and open loop state meeting and deposit between the spininess of connector.Therefore, traditional testing apparatus just can't be to its test, but directly by the operating personnel with multimeter one by one pin test, the test duration is long, efficient is poor, but also can be because operating personnel's misoperation cause mistake to survey.
Summary of the invention
Accurately to the electric property test of spininess connector, the utility model proposes a kind of test macro of the spininess connector electric property based on the NI data acquisition equipment for quick and convenient.This test macro is simple to operation, dirigibility by force can the arbitrary disposition testing needle quantity, versatility can be lacked open loop state between the arbitrary disposition spininess by force, and environment for use require low, be widely used in the field that needs test connector and can use, therefore be applicable to large enterprise to the test of batch spininess connector electric property.
The technical scheme that the utility model adopts is:
This programme carries out electric performance test as an example of USB-6501 NI data collecting card example to the spininess connector.
At first by the NI data collecting card on the needs testing needle output voltage, then remove to detect voltage on all the other pins by the NI data collecting card, judge whether it is that all pins all are completed, if be not completed, then need to continue to voltage of output on the testing needle, remove to detect voltage on all the other pins by the NI data collecting card again, judge whether again it is that all pins all are completed, until all pins all are completed.If be completed, then use the test procedure based on Labview of writing voluntarily that the data of collection and the data rows of standard are compared, if identical, represent that then the short open loop state between all pins meets our requirement; If not then the connector of explanation test does not meet our requirement.
Spininess connector electrical performance test system based on the NI data acquisition equipment is characterized in that: comprise test procedure, NI data collecting card, usb data line, winding displacement and spininess connector to be measured, wherein the NI data collecting card is used for sending and image data.Its connection features is: test spininess connector connects the NI data collecting card by winding displacement, and the NI data collecting card connects computer by the usb data line, and the Labview test procedure on the computer is controlled whole test macro.
Further, aforesaid spininess connector electrical performance test system based on the NI data acquisition equipment, it is characterized in that test procedure utilizes the Labview testing software to carry out communication with data collecting card, deal with data, and need for the user that short open loop state arranges the normal data row between the quantity of arbitrary disposition testing needle or arbitrary disposition spininess.
Further, aforesaid spininess connector electrical performance test system based on the NI data acquisition equipment, it is characterized in that data rows of data formation that test procedure gathers in the input port, relatively judge short open loop state between spininess by what data rows and normal data were listed as
Further, aforesaid spininess connector electrical performance test system based on the NI data acquisition equipment, it is characterized in that this system after the test end, passes through test when not only showing the spininess connector of testing, to also can in test procedure, not showing by the spininess connector of testing.
System stability of the present utility model, quick and convenient accurate, not high to environmental requirement can be widely used in the field that needs test connector, is particularly useful for large enterprise to the test of batch spininess connector electric property, and cost is low, and speed is fast.

Embodiment
Accurately to the electric property test of spininess connector, the utility model proposes a kind of test macro of the spininess connector electric property based on the NI data acquisition equipment for quick and convenient.This test macro is simple to operation, dirigibility by force can the arbitrary disposition testing needle quantity, versatility can be lacked open loop state between the arbitrary disposition spininess by force, and environment for use require low, be widely used in the field that needs test connector and can use, therefore be applicable to large enterprise to the test of batch spininess connector electric property.This electrical performance test system comprises test procedure 1; NI data collecting card 2; Usb data line 3; Winding displacement 4; Spininess connector 5 to be measured.Lower mask body describes the embodiment based on the spininess connector electrical performance test system of NI USB-6501 data collecting card in detail.
Based on the test procedure interface of Labview as shown in Figure 3.After connecting system, directly click the operation at VI interface, program can be moved with five following steps automatically, can show automatically PASS or FAIL after the program operation.This program is not only controlled the test process of whole system, can also need for the user that short open loop state arranges the normal data row between the quantity of arbitrary disposition testing needle or arbitrary disposition spininess.
The first step: the 24PIN on the NI USB-6501 data collecting card can be connected to arbitrarily on the connector that needs test.So, when corresponding connector is tested, spininess connector to be measured is attached on the I/O of USB-6501 NI data collecting card.
Second step: arrange that one of them passage is delivery outlet on the NI USB-6501 data collecting card, all the other are the input port.
The 3rd step: at voltage of delivery outlet output, then remove to detect voltage on all the other pins by USB-6501 NI data collecting card, judge whether it is that all pins all are completed, if be not completed, then need to continue to voltage of output on the testing needle, remove to detect voltage on all the other pins by USB-6501 NI data collecting card again, judge whether again it is that all pins all are completed, until all pins all are completed.
The 4th step: test all connector pins according to second step and the method in the 3rd step.
The 5th step: the voltage acquisition on all input ports is formed a data rows to the computer the inside, by comparing the relation of this data rows and normal data row, judge the short open loop state of this connector.Can dispose between the specific pin with the data rows of this standard and whether to be communicated with.
By the description of above structure and detection method, essential characteristics of the present utility model is clear and definite, its effect mainly be summed up as following some:
1, this utility model can need to be tested short open loop state between the quantity of spininess connector arbitrary disposition testing needle or arbitrary disposition spininess for the user.
