b. If the Result value is 0x4800, the device action logic is normal, the export feedback is normal, but the uploading of the background message is abnormal, and in this case, only the abnormal event needs to be recorded, and the recording file does not need to be stored.
c. If the Result value is not 0x4800 and the Result value contains 0x4000, it indicates that the test Result is abnormal, and the recording file is required to be stored for further analysis.
In the step SS5, the ATS platform waits for 30 seconds based on the following considerations: a large amount of wave recording files are generated in the automatic test process, and the wave recording conversion of the protection device has time delay; the existing specifications require that the fault recording file needs to be converted within 30 seconds, so that the waiting time of 30 seconds is set to ensure that the current recording file is required by the test.
In the step SS6, the ATS platform obtains the latest recording file from the protection device/COMTRADE folder in a file operation mode, and the file includes the following three format files: cfg,. dat,. hdr, the recording file is stored under Rec of the folder of the current test item.
In step SS6, when the ATS platform performs a file operation, a timeout of 30 seconds is set. If the operation time of calling the recording file exceeds 30 seconds and is still unsuccessful, judging that the acquisition fails, giving up the operation, and indicating that the acquisition of the recording file is overtime in an abnormal test report.
In step SS7, when a test exception occurs, an exception test report is formed, and the test exception is recorded in detail.
Compared with the prior art, the invention has the beneficial effects that: the invention can automatically acquire the fault recording file when the test is abnormal by realizing the automatic test. The method plays an important role in analyzing the reason after the fact, can accurately analyze the whole fault process, and can perform wave recording playback according to the wave recording file to simulate fault reproduction.
