Description
Technical field
The present invention relates to a kind of automobile instrument test platform, particularly to a kind of general automobile instrument exploitation testboard
Frame.
Background technology
Automobile Electronic Industry development in recent years is swift and violent, and wherein exploitation and functional requirement to automobile instrument are more and more multiple
Miscellaneous.Each car load factory is supplied to the signal type of automobile instrument and product interface definition is different from, even same whole-car firm
Different automobile types between, its signal type and interface definition also vary.This has resulted in different automobile instrument projects
During exploitation, exploitation testboard bay cannot be general, project will corresponding a exploitation stand, the most relatively costly, and seriously
Affect progress and the efficiency of project development.For improving exploitation testing efficiency, the compatible various automobile instrument interface definition of a energy, and
The exploitation stand of various signals can be provided just to seem the most necessary for automobile instrument.
Combination instrument exploitation testboard bay form the most commonly used in the trade has following several:
Directly pick out wire harness by instrument connector, corresponding wire harness inputs or export corresponding signal: use this
Kind of mode develops test, has the disadvantage that a). after instrument connector is drawn by wire harness, and easy confusion between each pin, it is difficult to point
Distinguish；B) be inconvenient to input the signal of Non-follow control change；C) easily loose contact causes signal input instability, affects product function
Judge: time d) actually used, extremely inefficient.
Jack type exploitation testboard bay: be designed with multiple Fructus Musae head jack, jack and instrument connector on this type of stand
Pin one_to_one corresponding, can be inputted corresponding signal by corresponding jack during use.This type of exploitation stand has relative to the first
Bigger improvement, can easily differentiate each input pin, and improve reliability.But also can have a disadvantage in that a) exploitation platform
Need on frame to introduce signal by external wire jumper, when being provided to the more signal of instrument, it is necessary to more wire jumper, make
Becoming wiring chaotic, be difficult to operation time actually used, reliability also can reduce.B) need to provide more external signal source device, account for
Use workbench larger space, use the most not convenient.
Tailored version exploitation testboard bay: as the term suggests, the type stand can only make for certain a automobile instrument product
With, it is internally integrated special signal module, directly can input corresponding signal by stand to automobile instrument, multi-hop will not have been produced
Line, the most convenient in operation, but this type of exploitation stand also can have the disadvantage that a) specificity is too strong, it is impossible to other instrument compatible
Product, when there being new product to need exploitation, it is impossible to using the exploitation stand of other products, can only redesign exploitation, increase is opened
Send out cost, affect project process；B), after needing automobile instrument all input signal types confirmation by the time, just can carry out stand and set
Meter, for instrument product is developed, often affects project development progress and causes project delay；It is c) too high due to specificity,
When instrument product function changes, generally require and stand is also carried out change, the most unfavorable to project development.
Summary of the invention
It is an object of the invention to as solving the problems referred to above, it is provided that a kind of general automobile instrument exploitation testboard bay.

Detailed description of the invention
The technical scheme provided the present invention below with reference to specific embodiment is described in detail, it should be understood that following specifically
Embodiment is merely to illustrate the present invention rather than limits the scope of the present invention.
A kind of general automobile instrument exploitation testboard bay as shown in Fig. 1 to Fig. 3, exploitation stand has been internally integrated instrument
Convectional signals module and interface, use unified power supply to power, and provide low and high level signal.According to automotive electronics characteristic, always electricity
Source rated voltage is defined as 12V, and in order to meet product development demand, it is allowed to the voltage range of input is designed as 0V ~ 40V.
Stand is internal containing 2 PWM module, 2 adjustable resistance modules, and to there being corresponding signal output interface
(PWM1/PWM2/R1/R2), for output pwm signal, square wave frequency signal and fuel oil resistance signal.Can be by PWM by wire jumper
Any one Fructus Musae head jack 3 that signal and resistance signal are linked in 1 ~ No. 32.Pwm signal module, scalable frequency and arteries and veins
Rush width.Frequency accuracy is 0.01HZ, frequency range 0 ~ 2MHz, it is sufficient to cover the frequency signal range of automobile instrument.With
Time this module there is LCD display function, the frequency of real-time and precise display current demand signal and pulse width, convenient regulation and test.
2 adjustable resistance modules use relay code Design, precision 0.1 Ω, Standard resistance range 0 ~ 2K Ω, cover the biggest portion
Divide kind instrument resistance signal range.Implement precisely to show current resistance with numeral method function, facilitate easy-to-use.With
Time this module devise memory function, 10 groups of resistance value data can be remembered, be used for rapidly inputting set resistance.
Toggle switch and Fructus Musae head jack module include 32 toggle switches 2 and 32 Fructus Musae head jacks 3, each stir out
The connection closing 2 correspondences has a Fructus Musae head jack 3, and this toggle switch 2 is third gear toggle switch, and each toggle switch 2 is provided with height
Level signal output, low level signal output and unsettled gear output.When toggling it to U+, export high level；Push U-, output
Low level；When pushing unsettled gear, other signals can be inputted, such as resistance, PWM etc. from the jack being connected with toggle switch 2.When stirring
When switch 2 pushes unsettled shelves, can be from corresponding Fructus Musae head jack input arbitrary signal to instrument.Some output signal of instrument is also
Can be from corresponding Fructus Musae head jack output.
Stand is connected with automobile instrument with wire harness by aviation plug.Toggle switch 2, Fructus Musae head jack 3, wire harness, instrument
Pin between a few person of connector, connects one to one according to sequence number.The instrument connector overwhelming majority is both less than in the market
In 32pin, considering based on compatibility, we have selected the aviation plug 4 of 32pin.
Due to the usual compact of CAN communication instrument, and product category and function are classified more, for convenience of using, and this money
Stand is integrated with DB9 jack 5 and the CAN communication interface of Fructus Musae two kinds of forms of head jack, and in view of the need of different instrument product
Ask, devise terminal resistance and select switch.
Slot tag 1 is used for placing instrument function indicating label.As shown in Figure 2, corresponding function is had only to indicate during use
Label out puts into slot tag according to gantry designs size marking, can be prevented effectively from input signal chaotic, improves test effect
