Description

Technical Field

[0001] The present invention relates to the technical field of power supply testing, and in particular to a testing method for an intrinsically safe power supply for mining. Background Art

[0002] Mining-grade intrinsically safe power supplies come in a variety of specifications and models, depending on their intrinsically safe output voltage, load capacity, and other technical parameters. These products have similar functions and, therefore, are highly similar in terms of function and performance testing.

[0003] Currently, during the R&D phase, software and hardware functional and performance testing of intrinsically safe power supply products for mining applications is mostly done manually. Testers first compile test cases based on the functional and performance requirements of the product design. They then verify each test case using visual observation or measurement tools, and finally manually produce a test report. If any issues are discovered during testing, they are fed back to the R&D staff for modification before manual testing is repeated.

[0004] The current manual testing method for mine intrinsically safe power supplies has the following disadvantages:

[0005] 1. Slow testing efficiency. Manual testing requires writing use cases one by one, manually operating instruments, and recording data. It is difficult to cope with complex scenarios such as multi-channel voltage / current detection and multi-operating condition verification, resulting in long test cycles and inability to implement batch testing.

[0006] 2. The test accuracy is low. Relying on visual observation and manual measurement tools is prone to reading errors. In addition, there is a lack of automated data collection and analysis functions, making it difficult to achieve continuous monitoring of high-frequency, high-precision parameters. In addition, manual operation is easily affected by subjective factors. Different testers performing the same use case may result in deviations in test results, making it difficult to ensure the consistency and traceability of test reports.

[0007] 3. High testing costs. During the development phase of mine-use intrinsically safe power supplies, hardware design and embedded software undergo frequent iterations, requiring cyclic testing. This leads to repetitive work for testers and a heavy workload, resulting in a significant waste of manpower and financial resources.

[0008] To solve the above problems, the existing technology has also proposed an automatic testing system. However, this testing system is mainly aimed at basic functional tests related to the factory inspection of mine-used intrinsically safe power supplies, and cannot fully cover the testing of all functional modules and performance indicators of mine-used intrinsically safe power supplies. The test needs to be combined with manual testing, which greatly affects the measurement efficiency and accuracy. Summary of the Invention
