Digital twin modeling system suitable for operation and maintenance of power tunnel

The invention provides a digital twin modeling system suitable for operation and maintenance of an electric power tunnel, and the system comprises a tunnel real scene modeling module, a tunnel data detection module, a detection position positioning module, and a model data integration module. Constructing a tunnel static model; the tunnel data detection module can detect environmental parameters in a tunnel; the detection position positioning module can position the real-time position of the data detection module during detection through a TOA ranging algorithm; and finally, the model data integration module can integrate the detection data to a detection position corresponding to the real-time position in the tunnel static model to generate a tunnel dynamic model, the data obtained through real-time detection in the tunnel is linked with the tunnel static model, complete data mapping of the tunnel from real to virtual is realized, and the tunnel dynamic model is generated. Therefore, operation and maintenanc
