Technical Field

[0002] In many industries, different types of workpieces are subjected to pressure holding tests to ensure their safety after production. The test process can test the stability of the workpiece under continuous pressure by maintaining a gas or liquid pressure higher than the working pressure inside the workpiece for a certain period of time. Through the pressure holding test, these potential safety issues can be discovered in time, and corresponding measures can be taken to repair or replace them to ensure the safety and reliability of the workpiece during use.

[0003] When the workpiece is undergoing a pressure holding test in the transmission mode, the staff usually observes and manually records the pressure changes of the workpiece with the naked eye within a specified time. This method is highly dependent on the skills and experience of the operator. Different operators may obtain different test results, which affects the reliability and accuracy of the test results. In addition, the use of paper records or simple spreadsheets to record data makes subsequent data query, analysis and storage more difficult, which is not conducive to the long-term preservation and traceability of data.
