[0052] In order to more clearly demonstrate the controller electrical performance testing method provided in the embodiment of the present application, the application scenario of the controller electrical performance testing method provided in the embodiment of the present application is first introduced.

[0053] The controller electrical performance testing method provided in the embodiment of the present application is applied to the controller before it is put into actual use. It is necessary to perform electrical performance testing on the controller to understand the performance stability of the controller under various workloads through testing.

[0059] Step S30, capturing the display screen of the tested controller through a camera, and obtaining a change state of the display screen of the tested controller based on the captured image of the display screen of the tested controller.

[0060] In this embodiment, a camera is used to capture the display screen of the tested controller during the test to obtain an image of the display screen of the tested controller. Based on the captured image of the display screen of the tested controller, the change state of the display screen of the tested controller can be obtained through analysis.

[0061] Step S40 , classifying the test results based on the voltage signal data and the current signal data, whether an error occurs in the message of the tested controller, and the change state of the display screen of the tested controller, combined with the restart state of the tested controller.

[0062] In this embodiment, the voltage signal data and current signal data of the tested controller, whether an error occurs in the message, the change status of the display screen and the restart status of the tested controller respectively represent the performance of the tested controller. These are combined and the test results are used to grade the performance of the tested controller.

[0063] Step S50, outputting a test result report after grading.

[0064] In this embodiment, after the test is completed, a test result report is output based on the test results after grading.

[0065] In this embodiment, during the electrical performance test of the controller, the display screen of the monitoring computer and the display screen of the tested controller are captured by a camera, and subsequent analysis is used to obtain whether an error occurs in the message of the tested controller and the change status of the display screen, thereby realizing efficient automation of the test process. No human intervention is required, labor costs are saved, and errors caused by reliance on manual labor are avoided. The performance of the tested controller is graded according to the voltage signal data and current signal data of the tested controller, whether an error occurs in the message, the change status of the display screen, and the restart status of the tested controller, and the electrical performance status of the tested controller is clearly and comprehensively understood through the test results.

[0066] Furthermore, in one embodiment, before step S10, the following steps are included:

[0067] A preset pulse interference signal is applied to the controller under test to perform an electrical performance test on the controller under test.

[0073] In this embodiment, the monitoring computer is equipped with monitoring software for monitoring various states during the testing process of the tested controller, including monitoring the curve states of the messages sent and received by the tested controller. The display screen of the monitoring computer is captured by a camera, and the message curve of the tested controller is obtained based on the captured image of the display screen of the monitoring computer. If the fluctuation range of the message curve exceeds the preset fluctuation range, that is, an abnormal fluctuation occurs, it means that an error has occurred in the message of the tested controller. If it does not exceed the preset fluctuation range, it means that no error has occurred in the message of the tested controller.

[0077] In this embodiment, a camera is used to capture the display screen of the tested controller during the test process, and multiple images of the display screen of the tested controller are obtained. The captured multiple images of the display screen of the tested controller are compared, and the changing state of the display screen of the tested controller can be obtained through analysis, such as whether the screen flickers, whether the screen brightness changes, whether the screen icons are displayed normally, and whether the screen is black.

[0078] Further, in one embodiment, the change state of the tested controller display screen includes whether the screen flickers, whether the screen brightness changes, whether the screen icons are displayed normally, and whether the screen is black. Step S40 includes:

[0083] The first level, the second level, the third level, the fourth level and the fifth level represent the electrical performance of the tested controller from high to low.

These are combined to divide the test results into first level, second level, third level, fourth level and fifth level representatives from high to low. If the voltage signal data or the current signal data exceeds the preset range, and the screen appears black, and the tested controller cannot automatically restart and recover to the working state after the test is completed, it is necessary to manually or automatically restart the tested controller by re-powering on the tested controller.
