Digital twinning system of regulating valve

The invention discloses a regulating valve digital twin system, and belongs to the technical field of equipment intelligence and digitization. The system comprises a device entity, a data acquisition system, a data communication system, a Unity visual platform and a Simulink model. The data acquisition system performs data acquisition in real time and sends a control signal to the equipment entity, and the Unity visual platform and the Simulink model establish data connection with the data acquisition system through the data communication system. According to the method, mechanism modeling of the pneumatic control valve is achieved through simulink by means of the twin model, the action essence of the pneumatic control valve can be reflected fundamentally, and therefore a foundation is provided for fault diagnosis and even prediction; a Unity-based three-dimensional visual platform can play a role in teaching and training, so that engineers can understand deeper; according to the MQTT-based data communication
