DEVELOPMENT OF CONTROL SYSTEM BASED ON LABVIEW HYDRAULIC PNEUMATIC INTEGRATED LABORATORY

Abstract

The liquid-pneumatic transmission method is a transmission method commonly used in today's electromechanical transmission facilities. It has the advantages of stable transmission, large transmission power, etc. With the development of science and technology, it plays an outstanding role in numerical control, engineering machinery, and automated production lines. The basic theoretical research of liquid-pneumatic transmission, the performance analysis and inspection of liquid-pressure products, and the operation status of testing equipment are all inseparable from the testing of various parameters of the liquid-pneumatic system. The hydraulic pressure test is the basis for realizing hydraulic automatic control. The feedback of signals such as pressure, speed and flow is the basis for calculating the control output. This article mainly introduces the experimental projects of multiple liquid-air element loops and the development of the test bench control platform based on LabVIEW graphical programming software. The test stand can complete the data acquisition and analysis and real-time monitoring of the hydraulic pump, proportional relief valve and proportional directional valve, and achieve real-time monitoring of various parameters in the experimental oil circuit
