Abstract: The scheme of universal multi-node synchronization measurement and control instrument based on fieldbus is proposed which is meet the development demands of mine hydraulic support equipment measurement system. Field bus network measurement and control technology is studied. The targets to be monitored are divided into multiple joints and units. Quest minion and sensor dynamic restructuring mechanism are used to realize the restructuring of measured targets. The platform adopts modular design, completed a specific instrument dynamic design and the multi-parameter data analysis online, measuring instrument measuring system using multiple targets on the measurement platform unified configuration and scheduling. Production results showed that the system meets predetermined requirements and validate the system's reliability and efficiency.
