Description
Technical field
The utility model relates to a kind of vehicle combined instrument durable test device.
Background technology
Automobile instrument is the interactive interface of people and automobile, it is important safety component, each car there is combination instrument, it is very large with the combination instrument performance difference of different automobile types that different suppliers produces, this just brings inconvenience for the checking work in product development process, and at present, there is no one can shorten proving period, also can meet the device of the test request of multi-product, this produces to the manufacture of vehicle and makes troubles simultaneously.
Utility model content
Technical problem to be solved in the utility model realizes a kind of proving installation that can carry out long duration test to various automobile combination meter.
To achieve these goals, the technical solution adopted in the utility model is: a kind of combination instrument durability test apparatus, comprise test board, and the power supply of to power for test board, described test board has and can send the controller of instrument signal by simulated automotive, and its signal output port connects tested combination instrument through wire.
Described test board is connected with signal testing computer through CAN card.
Described signal testing computer comprises main frame, the input be connected with main frame and display device, and described main frame is provided with the interface linking with CAN and connect.
Described power supply is furnished with uninterrupted power source.
The utility model has the advantage of, this device visuality is good, easy to operate, and be quick on the draw, reliability is high, is convenient to the requirements such as control.For company adds the test capability of this respect, reduce the outer test of committee and affect process of the test progress.When meeting test condition, this testboard bay infrastructure cost is low, easy to operate, long service life.In addition shelf structure is simple, compact, is easy to manufacture, and cost is low, easy to operate, long service life, and environmental pollution is little.
Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in the utility model instructions below and figure is briefly described:
Fig. 1 is testboard bay structured flowchart;
Fig. 2 is test board electrical installation principle;
Mark in above-mentioned figure is: 1, test board; 2, CAN card; 3, signal testing computer; 4, power supply; 5, tested combination instrument.
Embodiment
The utility model test unit can control to test for combination instrument back lighting, warning guidance lighting break-make frequency, test period control, speedometer, tachometer gage, fuel gauge, water-thermometer pointer running speed, test period.
Combination instrument durability test apparatus comprises test board 1, CAN card 2, signal testing computer 3 and power supply 4, test board 1 has and can send the controller of instrument signal (as used ST72F561 family chip according to the test logic of definition and sequential by simulated automotive, control to export various signal to combination instrument), this controller develops software based on LabVIEW platform and controls, first setup control parameter (cycle of operation, frequency etc.) in the software of LabVIEW platform exploitation, and Configuration Online hardware testing device signal; After operation, software founds rich L bus transceiver by Kvaser and exports corresponding test signal, and the signal output port of controller connects tested combination instrument 5 through wire, and such test signal is then input to instrument; Software also can receive combination instrument output signal, thus realizes the durable test to combination instrument.
Power supply 4 is connected with test board 1 for it is powered, and adopt the power source design of stabilized voltage supply+UPS, UPS is for providing protection during accident power-off.The gross output of stabilized voltage supply is no less than 0 ~ 30V/10A, output voltage 0-30V, continuously adjustabe from 0 to nominal, output current 0-10A, continuously adjustabe from 0 to nominal, stability of power supply≤0.2%+2mA, laod stability≤0.2%+2mA.
Test board 1 is connected with signal testing computer 3 through CAN card 2, and signal testing computer 3 comprises main frame, the input be connected with main frame and display device, and wherein main frame is provided with the interface be connected with CAN card 2.Test board 1 test parameter can be regulated like this, to adapt to the combination instrument of different model by signal testing computer 3.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
