Functional test function,
After product, which is put into test station, to be compressed, test platform test module combines the main operation controller product in circuit
DECONDING functions start to test to differentiate product type after receiving enabling signal；
Test platform applies the test signal simultaneously required every pulse of synchronous acquisition or simulation successively to correlative measurement pilot
Signal is measured, test is completed after a series of functional function operations, is providing test result and jump out test loop, under waiting
Primary operation.
The embodiment of the present invention is small for automobile engine cooling fan controller this species diversity, wide in variety, each not phase of yield
With product, use a kind of universal hardware and software platform pattern to design the test equipment of production.Different products is connected
Into the test interface circuit of standard, by going to call the test program of different product come real to the address decoding of product support plate
Now test.The advantage of doing so is that without manufacturing new test equipment for new product every time, more new procedures can be realized pair
Test, the production of new product.
Such test platform pattern both may be implemented a small amount of test instrumentation or can accomplish difference in actual production
The small lot of type product produces；Dozens of test platform can also be arranged to work at the same time to realize the requirement of mass production.
It is a kind of reproducible, propagable hardware and software platform scheme.Be conducive to accessory standardization, maintenance criterion, staff training is rapid, production
The extension of product line is a kind of production capacity deposit of stealth again when requiring, this synergy again of drop.
Specific implementation mode
According to one or more embodiment, a kind of automobile engine cooling fan controller general-utility test platform, this is logical
Include with test platform：
Standard interface；
Master controller；
Test module combines circuit, and test module combination circuit is connect with standard interface；
Replaceable support plate, the replaceable support plate are connect with standard interface, and replaceable support plate has multiple models, with automobile
The model of cooling fan of engine controller corresponds to, and support plate is tested fan governor, while the survey on support plate for carrying positioning
Examination thimble is wanted to contact with the test point of tested fan governor circuit, realizes that test module combination circuit passes through standard interface pair
The electrical connection test of tested fan governor.
In hardware and software platform test system, the electronic control electricity in being main platform body structure positioned at " standard interface " side
Road is one kind based on circuit structure made of the combination of company standard test module.Positioned at " standard interface " other side be by
The automobile engine cooling fan controller product of test and the support plate positioned for it.Different support plates is replaced to can be realized
Switching between different product achievees the purpose that platform is general.
In one or more embodiment, the standard interface of connection automobile engine cooling fan controller product is
DB25 core connector standard interfaces.After to Related product test request induction-arrangement, the DB25 cores for choosing international standard connect
Plug-in unit simultaneously defines each pin therein, and different product is connected to corresponding PIN according to specifically defined (the signal classification) of pin
On foot, realize and the transmission of signal and the connection of system；The signal definition that simple method solves between different product is skimble-scamble
Problem.
In one or more embodiment, test module combination circuit includes：
1) input of ordinary numbers amount and ordinary numbers amount output module；The signal for serving as the human-computer interaction of test platform connects
Mouthful, including enabling signal, product address line signal, test passes and unqualified signal, LCD display data-interface etc..It selects
High performance chips AC30, reached the dual function of driving capability and interference and insulation.
2) high-speed pulse input and high-speed pulse output module；Specific implementation be pulse-width modulation PWM signal output with
Frequency is up to the data acquisition of the high speed pwm signal of 20K.Different from common photoelectric isolating device, high-speed photoelectric coupler part
6N136 microcontroller acquire 20K high-speed pulses during not only acted as high efficient and reliable be isolated interference signal and also its
The external signal for being up to 1MHZ can be effectively transferred to microcontroller by distinctive high-speed transfer performance.In the 6N136 of another way
In channel, the lock-out pulse which is converted into meeting product voltage magnitude by the pwm control signal that microcontroller occurs again is added to
The signal control terminal of product is realized to the function of product plus signal.
3) multichannel analog amount Signal-regulated kinase；It needs to monitor various analog datas, the electricity of product in test system
Pressure, LDO chip output amplitudes, product stall and short-circuit signal, the also output of related sensor is all analog data.The mould
Some of the above signal condition is mainly then transferred to microcontroller processing in this way by block at the voltage range that microcontroller can recognize
A signal condition effect.Tested test unit's milli can be told by equally possessing the analog-digital converter (ADC) of 12 precision
Lie prostrate the variation of voltage, the test system higher than 10 bit resolutions more on the market of data accuracy at double.
4) output module of high-precision DA signals；The work that digital quantity is transformed into analog quantity is mainly reflected in test system
Some of the control of the programmable power supply of power supply and interiors of products needs simulated two aspects of application of load signal.Power supply
Program-controlled mainly test system needs the working environment of the controller in simulated automotive storage battery under different electricity, is realized using programming
The purpose of dynamic control voltage.
The combination of some of the above circuit resource easily meets generation and the various unlike signal demands of acquisition, that is, realizes system
One modularization meets unlike signal complicated test request mixed in together again.
