In order to test the performance parameters of hydraulic pump, a measurement and control system for hydraulic pump test-bed is designed, using industrial computer and PCI data acquisition card as its core, LabWindows/CVI as software development platform. Application is designed based on multithreading technology, and using thread safe variables to synchronize threads. The automatic collection,analysis and display of each parameter is realized. The temperature of oil is controlled between 35~45℃ using hysteresis control algorithm. The pressure control of the oil outlet and the oil return port is realized by advanced PID algorithm. Humanized alarm function is designed. Operational parameters are stored in the database per-second through ODBC interface, which can effectively resolve faults when it occur. The debugging interface save the site-testing time greatly. By experiment, the system satisfies design request.
