The zero environmental parameter refers to an environmental parameter that does not need to be monitored during the test process. Typically, the zero environmental parameters include temperature parameters in normal temperature common tests, and environmental parameters such as dust, rain, smoke, and the like which are difficult to monitor.

The univariate environmental parameter refers to setting only one environmental parameter as a variable in the test process, for example, only changing one of the environmental parameters such as temperature, humidity, vibration, impact, dust, light, air pressure and the like in the test chamber.

And when the environment actual measurement parameters in the test box or the test data of the terminal equipment to be tested are abnormal, performing abnormal alarm to realize automatic intervention or inform a tester to execute manual intervention. By matching different test types with different anomaly analysis mechanisms, a test data anomaly analysis algorithm is improved, and remote monitoring of test data is realized through a cloud server, so that the test efficiency and the effectiveness of the test data are improved.

Step S433: and calculating a difference value between the preset power supply parameter and the power supply actual measurement parameter, and determining whether the power supply actual measurement parameter is abnormal or not according to a comparison result of the difference value and a preset power supply deviation threshold value.

In this step, taking the power supply actual measurement parameter as the power supply current and the preset power supply deviation threshold as the preset power supply current deviation threshold as an example, the cloud server may calculate a difference Δ I between the actual measurement total power supply current and the preset total power supply current of all the terminal devices to be tested connected to the power supply device, if the difference Δ I is greater than the preset power supply current deviation threshold, the power supply device may be controlled to independently perform power-on and power-off processing on each terminal device to be tested, sequentially collect the actual measurement sub power supply current of each terminal device to be tested, calculate a difference Δ I between the actual measurement sub power supply current and the preset sub power supply current, if the difference Δ I is greater than the preset power supply current deviation threshold, it is determined that the corresponding terminal device to be tested is abnormal, and the cloud server sends a terminal device abnormality alarm to the tester.

Step S434: and calculating the error rate between the preset message parameter and the test message value, and determining whether the test message value is abnormal or not according to the comparison result of the error rate and the preset error rate threshold value.

In this step, the cloud server obtains a message value carrying test data uploaded by each terminal device to be tested, compares the actually received message value with a preset message parameter, calculates a message error rate Δ Dw, determines that a communication channel between the terminal device to be tested and the cloud server is abnormal if the error rate Δ Dw is greater than a preset error rate threshold, and sends a terminal device abnormality alarm to a tester.

Specifically, the steps S431 to S434 are applicable to an application scenario in which the test environment does not need to monitor the environmental parameters. And after the environment actual measurement parameters in the test box and the power supply actual measurement parameters of the power supply equipment are obtained, the environment parameter abnormity judgment is not executed. Acquiring specific time of equipment abnormity through the sudden change time point of the total power supply current; through the analysis of the sub-supply current, the specific terminal equipment which is abnormal is positioned; the cloud server is used for remotely checking the message value, further identifying abnormal equipment, realizing accurate positioning of the abnormal terminal equipment, and alarming for abnormality, so that the labor cost and time cost of testing can be reduced, the abnormal testing can be timely checked through data monitoring, and the testing efficiency and the effectiveness of testing data can be improved.

Step S442: and determining an environment parameter fluctuation threshold according to the mean value mu and the standard deviation sigma of the plurality of environment actual measurement parameters, and judging the environment parameter abnormity according to the environment parameter fluctuation threshold.

In this step, the environmental parameter fluctuation threshold includes an upper threshold μ + σ and a lower threshold μ - σ, and it is determined whether the environmental measured parameter exceeds an environmental parameter fluctuation threshold range (μ - σ, μ + σ), and if the environmental measured parameter exceeds the environmental parameter fluctuation threshold range (μ - σ, μ + σ), it is determined that the environmental parameter abnormality occurs in the test chamber.

In one embodiment, a tester can adjust the theoretical value of the environmental parameter and the abnormal triggering condition through the cloud server, and the abnormal detection algorithm is favorably optimized.

Step S443: and calculating a difference value between the preset power supply parameter and the power supply actual measurement parameter, and determining whether the power supply actual measurement parameter is abnormal or not according to a comparison result of the difference value and a preset power supply deviation threshold value.

Step S444: and calculating the error rate between the preset message parameter and the test message value, and determining whether the test message value is abnormal according to the comparison result of the error rate and the preset error rate threshold value.

Specifically, the above steps S441 to S444 are applicable to an application scenario in which the test process employs a constant variable environment parameter, for example, the environment variable is set to be maintained at 85 ℃. After obtaining the environment actual measurement parameters in the test box and the power supply actual measurement parameters of the power supply equipment, firstly, calculating a mean value mu and a standard deviation sigma of the currently acquired actual measurement temperature, wherein the environment parameter fluctuation threshold comprises an upper limit threshold mu + sigma and a lower limit threshold mu-sigma, judging whether the actual measurement temperature exceeds the environment parameter fluctuation threshold range (mu-sigma, mu + sigma), and if the actual measurement temperature exceeds the environment parameter fluctuation threshold range (mu-sigma, mu + sigma), judging that the environment parameters of the test box are abnormal. After the environmental parameter abnormality judgment is completed, whether the terminal device abnormality exists is judged through the power supply actual measurement parameter and the message value, and the method is consistent with the embodiment and is not described again. By newly adding a monitoring and abnormity judging strategy of the test environment, the remote monitoring and control of the test box is realized, and the effectiveness of test data is improved.

In one embodiment, when the test chamber is used for sampling the environmental parameters, an environmental monitoring module (such as a temperature sensor) can be arranged on the surface of the terminal device to be tested. For example, when the terminal device to be tested works in an environment of 85 ℃, the actual working temperature of the core component of the terminal device to be tested can be determined by testing the temperature of the surface of the shell or the circuit board of the terminal device to be tested, so that temperature rise information is obtained, and a basis is provided for optimizing heat dissipation and designing a structure.

Step S452: and performing polynomial fitting on the environment actual measurement parameters and the power supply actual measurement parameters, and performing abnormal judgment on the environment parameters according to the deviation rate of the environment actual measurement parameters relative to a fitting curve.

Step S453: and calculating a difference value between the preset power supply parameter and the power supply actual measurement parameter, and determining whether the power supply actual measurement parameter is abnormal or not according to a comparison result of the difference value and a preset power supply deviation threshold value.

Step S454: and calculating the error rate between the preset message parameter and the test message value, and determining whether the test message value is abnormal according to the comparison result of the error rate and the preset error rate threshold value.

Specifically, steps S451 to S454 described above are applicable to an application scenario where the test process employs variable environmental parameters, for example, setting the test chamber to perform temperature cycling or temperature shock between-40 ℃ and 85 ℃. The environment measured parameter is a variable parameter, and the trend of the environment measured parameter (such as temperature) changing along with time has correlation with the trend of the power supply measured parameter (such as measured total power supply current) changing along with time. When polynomial fitting is carried out, curve drawing can be carried out by taking the temperature as an abscissa and the actually measured total power supply current as an ordinate, and a fitting curve is obtained based on a polynomial fitting mode. And calculating the deviation rate between the actually measured temperature and the fitting curve, and if the deviation rate exceeds a preset deviation rate threshold value, judging that the environmental parameter is abnormal. After the environmental parameter abnormality judgment is completed, whether the terminal device abnormality exists is judged through the power supply actual measurement parameter and the message value, and the method is consistent with the embodiment and is not described again. By newly adding a monitoring and abnormity judging strategy of the test environment, the remote monitoring and control of the test box is realized, and the effectiveness of test data is improved.
