[0002] With the continuous development of industrial production, the quality inspection requirements for various products are becoming increasingly stringent. Among the many product tests, load testing is a key step in evaluating product performance and reliability. For example, in industries such as machinery manufacturing, automotive parts production, and electronic equipment manufacturing, products need to withstand different levels of load forces during actual use. Therefore, accurately simulating and testing the performance of products under load conditions is crucial.

[0003] During use, existing load testing machines typically collect various parameters of the load testing machine through data acquisition, determine whether there is a fault in the load testing machine based on the parameters, and promptly issue an alarm to remind the staff to handle the problem when a fault is found.
