Research and Application of Digital Twin System in Coal Mining Working Face of Coal Mine
In response to the lack of real-time monitoring and prediction capabilities,limited video signal perspectives,and dust interference in the 31311 working face of Wanli No.1 Mine in Ordos,a digital twin system is proposed.The system architecture is constructed through physical perception layer,data layer,business logic layer,and presentation layer,and data collection is carried out using optical fiber,Modbus,CANBUS,Profibus,OPC,and wireless communication methods.The data collected by sensors is transmitted to the client through PLC and OPC servers,MQTT is used for real-time data forwarding,and MySQL is used for historical data storage.The visualization platform is based on the Unity engine,combined with HTML5,CSS,and JavaScript,for 3D modeling and rendering,and achieves high-precision lightweight modeling through 3ds Max.The system has successfully achieved real-time monitoring,status feedback,and intelligent control of the working face equipment,solving the problem of low visibility in traditional video monitoring and improving the automation level of the working face.The practical application of the system has significantly improved the efficiency and safety of the workplace,assisting in the digital transformation of workplace scenarios.
