Performance parameter acquisition and disposal system of high pressure valve class products based on IPC

Based on the control system of IPC and industrial configuration software, the problem of collecting and storing in high speed of performance parameters of high pressure valve class products was solved, and data display, as well as curve analysis was realized. The real-time frequency signal for flux of flow meter was measured with high accuracy by using high speed counter of PLC. With the innovating alteration for high pressure manual regulator valve which be used in system, auto-regulation of valve opening was carried out in high pressure instance. A universal test-platform for different valves was designed. This data acquisition system has been used in a project of performance parameter testing of military valve class products, the upper limit date picking rate can reach to 20 times/s and the measuring precision can reach to 0.3%.
