Further, test case is for each instrument to be measured or reference instrument distribution marker, instrument matching module base
Corresponding instrument to be measured or reference instrument are recognized and match in identifier.
The invention also discloses a kind of automatic test approach of digital measuring instruments, employs a kind of digital measuring apparatus
The Auto-Test System of device, it is comprised the following steps：
1）Test condition is arranged by user interactive module and test case is loaded；
2）Test system loads the test module of varying number according to test condition；
3）Instrument matching module determines instrument to be measured and reference instrument and is matched and communicated；
4）Instrument command set module configures instrument to be measured or reference instrument according to test case；

7）Data processing judge module is based on Test data generation and preserves test result.
Further, it also includes step 8）When needing to change test combination, instrument to be measured is replaced by into same type
Reference instrument, by reference instrument the instrument to be measured of same type is replaced by, and records corresponding by user interactive module
Test case.
Further, the test result saves as csv files.
Below just the particular content of the test system of the present invention is described in detail：
User interactive module, is that whole test cases have been write in later importing program, in user interactive module, can be chosen
The instrument that this test is used, can select to perform those test cases, the number of times that use-case is performed, and the order for performing, such as
Out of order, order.Check use-case that is current and having performed and result.Friendly interface uses for tester.Using pure text
The mode of this editor test case, considerably reduces programming difficulty required during editor's test case, so as to reduce the time
With the input of energy.
Test environment referred to test the function of instrument to be measured, index, a set of reference instrument of required difference in functionality.
Some reference instrument approved in the industry in different function or function group test environment as instrument parameter to be tested,
The criterion of index.When the test instrument to be measured in a upper test event is changed into reference instrument, will be a certain in test environment
Reference instrument changes our equipment to be tested into, is so achieved that multi-composite type automatization test system, and due to test
The durability of environment, has greatly saved the expensive instrument expense set up for different product needed for different test environments.
The modules that test program includes are in structure the relations of upper and lower level, between each layer are entered with information conduit
Row communication, such structure is reduced as far as possible, the coefficient of coup between modules.Can realize when a certain level needs modification
It is the normal work that can't affect other level.
Instrument command set module, realizes and goes to configure each instrument with the mode of plain text editor's test case.Instrument order
Collection, including instrument configuration, for the agreement of the addition that cooperates, such as idle, wait between the order of acquisition data and each flow process,
Timeout etc..These orders are, for constituting test case, also to provide guarantee for the work that cooperates between each instrument.
Instrument driving module can parse these test cases with plain text editor, and be transmitted to each instrument by function, from
And complete automatic test course.
Instrument driving module, using standard I/O function library and its specification of correlation, performs the function of instrument bus, the mould
Block is realized by the interface of a standard, the management of access and resource to physical resource, effectively shields different bus
Between difference, make upper strata interface will not on bus produce impact.
Instrument matching module, is, per a series of instruments that be added to test environment, in test case text the time-division to be write
With special identifier, after into program execution flow, matched, hence into different flow processings, and then matched somebody with somebody
Put, read instrument parameter, corresponding instrument is found during data.Because different flow processs is for different parallel threads, this
Sample is just unlikely to program and causes confusion to cause mistake will be synchronous and parallel when.
Data processing judge module, test data is obtained from each reference instrument or instrument to be measured, and test data is to sentence
The key parameter whether disconnected test result passes through, form is all not quite alike after being come up due to these test datas acquisitions, such as
These data are changed, calculated, contrasted by character type, Wave data, hexadecimal data etc., data processing judge module,
And the judged result of parameters can be combined, contrasted, be screened, finally draw each test case by whether
Result.So as to complete test assignment.
Further, the method for testing specific workflow of the present invention is elaborated：
Tester arranges first some test conditions and option of this test by user interactive module, loads pre-edit
Good test case, test system loads different modules according to test condition, and instrument matching module determines instrument to be measured and auxiliary
Help instrument and matched and communicated, it is to be measured that instrument command set module calls different instrument command sets to configure according to test case
Instrument or reference instrument, instrument driving module parsing test case is respectively provided with instrument into different states, then reads
The data come up transfer to data processing judge module, draw the test result of the test case and result is saved in into csv files
In, it is convenient to analyze and statistics, and then complete the test row of a rule.
The result of artificial judgment is needed to some, our system also has automanual function, and exactly instrument is all arranged
It is good, finally the testing result of the test case is provided by tester and preserved.Thus can cover widely
Test content and classification.Because these modules can be coordinated, efficiently operate, allow our test system basic at nobody
In the case of on duty, test case is continually performed, until the test case of all loadings has been performed, often operation in afternoon
Test system, waits come to analyze test report within second day, just completes a wheel and tests.
As shown in figure 3, further, since the instrument classification of production is more, functionally there is complementation between different instruments again
Relation, this just provides guarantee for many combined characteristics of automatization test system of the present invention.As shown in figure 1, embodying the present invention
Many combined characteristics, it is assumed that one for instrument A to be measured test assignment in, test environment is by standards such as reference instrument B/C/D
Instrument is constituted, and after the test for performing several wheels, the test assignment of instrument A to be measured has been completed.It is another for instrument to be measured
The test assignment of device F will start, and now we need to only change original instrument A to be measured into generic reference instrument E, will mark
Quasi- instrument D changes instrument F to be measured into, and other test environment all need not change, as long as loading the test case of current test assignment,
And testing results system, begin to for the test assignment of instrument F to be measured, very facilitate, efficiently.
The present invention adopts above technical scheme, by plain text editor's test case, the automatic test system of multi-composite type
System, it is possible to achieve 24 hours substantially unattended fast, easily systematic testings.Reduce opening for automatic test programming
Cost is sent out, the flexibility ratio of automatic test enforcement is improve.Many combinations are carried out to reference instrument according to different test environments, is subtracted
Lack the multiplexing that build and increased test environment of tested environment, extend the applicable scope of automatic test, Neng Goujin
Row is to the automatic test task more needed for the complicated test network of equipment to be tested and multiple stage subtest equipment composition.
