Design of Digital Twin-driven Integrated Control and Monitoring System for Transmission System

Aiming at the problems of high cost, low efficiency, lack of real-time performance and visualization in existing control and monitoring methods of mechanical transmission system, an integrated control and monitoring scheme of mechanical transmission system based on digital twin is proposed. First, the detailed design of mechanical and electronic control system of physical platform was carried out. And the digital twin model was developed by Solidworks, 3ds MAX and Unity3D. Second, the hardware of monitoring and diagnosis system was built by piezoelectric accelerator, data acquisition instrument and upper computer. Meantime, the software was developed by LabVIEW. Finally, the transmission system fault test platform was used to carry out nine kinds of rotor imbalance test with different speeds and imbalances. The database was created by MySQL. Through experimental verification, the speed of digital twin model can be controlled and the historical or real-time data can also be invoked to drive the digital twin model. When the model was driven by experimental data, the user interface displayed the current state as rotor imbalance, and the turnplate was highlighted, which proves this work feasible and effective.
