A set of pressure bearing performance test system for borehole inclinometer was developed based on LabVIEW. In the system, pneumatic booster pump was used as the actuator of the pressure loading unit, highprecision pressure sensor was used as the closed-loop control feedback element of the whole system.Through the combination of virtual instrument technology and PLC control technology,the electric proportional valve was controlled in real time to realize the pressurization function of the system. By using the system, not only the pressure, pressure boost rate and pressure holding time of the hydrostatic test can be set, but also the number of fatigue tests can be set. Various test schemes can be set according to these parameters to accurately pressurize the tested samples. The system can display the real time p-t curve and hold pressure time in the whole test process, and can effectively monitor the working state of the system.By using the system, the data is automatically displayed and recorded, the test results are automatically input into the database and saved, and the test record sheet and test report sheet are automatically generated and printed out by exporting the report
