Standby instrument is also to be connected by USB controls with industrial computer.
Hardware bottom layer height decouples
Each functions of modules of intermodule is independent, is independent of each other.Main control module is by the way of isolation, between finite reduction circuit board
Interference signal；Industrial computer can change battery core voltage, function of current, it is ensured that the precision of equipment is maintained at certain range
It is interior.
Good autgmentability
The group pattern that hardware uses, the extension of support group, user can set existing equipment according to the shipment amount of product and test
Channel could support up 2 channels and test simultaneously.
Connection conduction mode between hardware and test product：
Connection is connected using following medium between equipment and product：Needle bed, fixture, probe, conducting wire；
Needle bed is connect with conducting wire, and wherein needle bed is connect with the output port of each lane testing plate using " matrix slot ", and each logical
Road test board output port is " formula slot "；
Needle bed is adopted be screwed in itself, and carrying out contact with test fixture needle plate solder joint is connected, and control its conducting is to pass through
The vertical direction of cylinder operates conducting up and down.
And the probe on needle plate fixture operates up and down with the vertical direction of cylinder, and form disengaging with the test point of product
With engaged test point.
Software interface is divided into 4 regions, is toolbar, channel status, test event state, basic statistics four respectively
A region.
Channel status area：Display layout is consistent with the next hardware arrangement, and from right to left, the combinations of states of 5 groups of hardware rises
To form a channel.State divides into two parts up and down, upper part be shown last test as a result, lower face
Divide the result phase that current test product is shown.Channel status contains following several situations：It is bad track, bad plate, to be measured, good
Plate, hollow plate, accident.State is distinguished by color, and bad track is displayed in red with bad plate, display sky blue to be measured, good plate display green,
Accident shows black with hollow plate, and user can intuitively judge the situation of product by color.
Test event display area：During the test, the result of item display area can be shown in corresponding cell
In, while the range of test event can be also compared, defective products is intercepted.When red occurs in test event cell
During background, then illustrate that this test does not pass through, user is analyzed according to this test.Test method container is realized：
The principle of test method container：
Underlay approach encapsulates：
The required function of packaging and testing carries out bottom, provides unified entrance, the content of encapsulation is contained to master control module, electricity
The control of core model group, electric current module, Agilent power meter, the situation of parameter change that the realization of function is mainly passed to is more,
Therefore, the interface of parameter is exposed, required function is packaged.
Step debugger
Step debugger is the interface of adjustment method, major function be verification to methodological function, the single-step debug of product and
Test event writes function.The layout of debugging is made of method list, aggregate list, toolbar, channel selecting region, need to
The method wanted is added in container and then clicks operation and debugged, can in aggregate list parameter 2, change in parameter 3
The value of parameter.For the method set that multiple methods are composed, a test event can be formed, then the guarantor on click tools column
Button is deposited, input title saves as a test event.Debugger opens test event and carries out checking testing procedure.
It should be noted that test method set be serializing after with the form of xml be stored under Current software catalogue when
In the file of preceding product type, main program is searched in test product, by the title of test event under above-mentioned path pair
The xml document answered is tested.File adds strong NameSpace after serializing, and non-such software can not open editor,
Therefore, it is possible to which external factor is effectively prevent to distort test event step.
Testing procedure in test event, parameter source could be provided as other specific dynamic parameters, such as can set
It is set to TCH test channel, testing procedure N（Which step N represents）, it is only necessary to it is set in parameter source.In actual test process
In, it can be dynamically distributed according to current situation, such as parameter source 1 is set as TCH test channel, when starting test, test is logical
The value in road is 11, and during the test, unfavorable condition occurs in the product of 1 channel, then current TCH test channel does not include 1 then
The test case of channel, the value of TCH test channel can be changed to 10；
Debugger only supports the production debugging of a channel, and the production debugging stage follows letter to difficult, process from less to more.
When debugging product, first debugging has verified that a channel is debugging other channels, when all channels all debug completion, then carries out
All channels are verified together.
Software has the situation of automatic sense channel, the situation for preventing the anti-inserted leakage of test module slotting.
Test event test process：
By test event configuration interface, after the parameter of test event has been configured, the integrated testability of next step could be carried out.
During test, test product model is selected, the designer integrality under systems inspection current production title, it is ensured that existing
Test event all exist.According to preset test event order, item file is loaded, and according to the method set of file
Corresponding class is called, the result after execution is compared, document method is performed into completion, then carry out next project.
Test result preserves：
After the completion of integrated testability, test detail can be stored in the machine computer and network data center simultaneously.User can be real-time
Inquire the situation of product test.The retrospect of subsequent product provides query function.
It should be noted that during product test, the connection situation of the heartbeat packet network data center of use is kept away
Exempt to cause preservation data time long since network is obstructed, influence the production of product.When detecting Network Abnormal, software will be surveyed
Test result preserves in the buffer, and after network is normal, data are uploaded to data center by the journey that individually bursts at the seams, and prevent the resistance of main thread
Plug.
Operation logic of the present invention is described in detail above, the explanation of above-mentioned operation logic is merely used to help understand
The method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, thought according to the present invention is having
There will be changes in body embodiment and application range, in conclusion the content of the present specification should not be construed as to the present invention
Limitation.
