A design method for measurement and control software based on hydraulic circuit graphic component was introduced, and an example of applying hydraulic circuit graphic component to the measurement and control system was given.In this method, Python was used as the primary programming language. Combined with the PyQt library, the data of various physical quantities in the hydraulic system can be collected and monitored, and the interaction among hydraulic components can be enhanced. It has great significance to promote the development of hydraulic measurement and control technology towards friendly, integrated and intelligent direction
