Abstract


In coal mining , hydraulic support for the smooth conduct of the mining protection stent valve is the key control elements . Hydraulic valve to the high pressure and large flow development goals. In practical applications , hydraulic valves must be through a variety of performance tests , before use. Hydraulic valves , hydraulic valve test rig developed provides a platform , will surely contribute to the development of hydraulic valves . The traditional test system , due to the influence of human factors , the accuracy of the testing process and the results are not high , you can not reach the testing requirements of modern hydraulic valve . The emergence of the hydraulic computer aided test (CAT) , marking the testing technology fully into the computer age , but also the development of today 's hydraulic test system direction . Hydraulic valve test computer control systems based on electro-hydraulic technology based . The use of computer technology and sensor technology , the hydraulic valve test standards for performance testing the hydraulic system of the hydraulic valve test bench . Based on the technical requirements of the test rig and hydraulic valve test standards to determine the overall scheme of the test bench , modular design concept to design the schematic diagram of the hydraulic system . In terms of control , the use of a programmable controller for automatic operation . The whole control system is divided into hardware and software design . In terms of data collection , the configuration of the sensor , can automatically measure the performance parameters and display data in the display , curve . PLC and host computer communication , using the free port serial communication protocols S7-200 series PLC programming with VB , PLC and computer communications .
