Research on Key Problem of Intelligent Test System for Solenoid Valve

An intelligentized, comprehensive and high efficiency test system of solenoid valve for oil medium is designed in this paper, aiming to the disadvantage of current test devices in most solenoid valve factories in China. Serial communication of OPC-SERVER, sequential control of PLC, frequency conversion speed regulation technology and data acquisitions by LabVIEW are all achieved in this system; modeling and simulation on the whole system are built by AMESim and Matlab; fuzzy PID controller is designed on the pressure of system, so intelligent optimization control on system is realized. The old manual test method will be replaced by this system with high precision, automatic test process achieved. Test efficiency of solenoid valve will be improved, and the reliability of test results will be guaranteed.
