This paper introduces a test system of transmission shift control valve.PLC and LabVIEW are used for program development to realize the control of the test system and the processing of test data,and under the premise of meeting the test conditions,the modular method is used to deal with the complex test requirements.The experi-ment shows that the system can greatly improve the development efficiency of the test system and the hydraulic test level,and can provide convenience for troubleshooting.
