Scheme delay is produced, its production is influenced, causes its direct or indirect economic loss, thus it is guaranteed that delivery date is also power consumer
There is an urgent need to.
For power quality controlling equipment manufacturer, it is ensured that the reliability of product, in addition to when design
It gives except enough guarantees, in the production process of product, needs to do product debugging as detailed as possible and test, and
Debugging and test process should use up accomplish may more than automation, to avoid caused by human factor in production debugging and test process
Damage is omitted.In addition, for tested product there are the problem of, should be as far as possible in early detection, in order to avoid sudden and violent in late problems
Dew causes failure propagation, causes additional production to be lost and reduces production efficiency.And this requires the tests of early stage should
Cover all hardware circuits as far as possible, so that the workload of test greatly increases, it is ensured that testing efficiency, using product
Automatic debugging, test are clearly necessary means.
Damage caused by human factor in production debugging and test process can not only be avoided using automatic test or lost
Leakage, while testing efficiency can also be greatly improved, the production reliability and production efficiency of product are improved, production week is shortened
Phase.

Fan-status；
Tested each bridge arm temperature value of APF/SVG module is acquired, temperature sensing circuit state is analyzed.
6. the automatic calibration test method of APF/SVG module according to claim 3, which is characterized in that the step S5 includes
Following steps:
Step S5.1: when the dry run test of the tested APF/SVG module of main control process flow operation, then it is tested APF/SVG module mould
Quasi- operation testing process is called, runs test mode into module simulation；
Step S5.2: dry run test program is downloaded to tested APF/SVG module；
Step S5.3: judge whether tested APF/SVG module downloading dry run test program succeeds；If success enters step
Rapid S5.4 is continued to execute；If not succeeding, prompt window is popped up, tester is allowed to choose whether to re-download dry run survey
Program is tried, if tester's selection carries out re-downloading calibration and unit testing program, return step S5.2 is continued to execute, if
Tester's selection does not re-download dry run test program, then it is assumed that test crash；
Step S5.4: APF/SVG module must be tested and enter dry run test mode；
Step S5.5: instruction is sent to tested APF/SVG module, skimulated motion testing procedure is executed, obtains test data；
Step S5.6: the performance indicator of tested APF/SVG module is calculated using test data obtained.
7. the automatic calibration test method of APF/SVG module according to claim 6, which is characterized in that in the step S5.5
In, following dry run testing procedure is successively executed, to obtain test data:
Obtain the state of tested APF/SVG module；
Control tested APF/SVG module booting operation；
It controls tested APF/SVG module and issues specified current flow；
It reads tested APF/SVG module and runs Wave data.
