A tunnel boring machine display method and system based on a three-dimensional model

The invention provides a tunnel boring machine display method and system based on a three-dimensional model, and the method comprises the following steps: a data collection module collects the data ofa PLC controller and a guiding system of a tunnel boring machine in real time, transmitting the data to a database through a network, and stores the data; The three-dimensional modeling module performs three-dimensional modeling according to the type of the tunnel boring machine; The model data driving module inputs data in the database into the three-dimensional model, and drives the three-dimensional model to be linked through real data to realize three-dimensional real-time display; And the virtual interaction module performs simulation data interaction with the three-dimensional model torealize equipment disassembly, model assembly or construction simulation. According to the method, the whole state of the tunnel boring machine in the construction process can be personally sensed without at the construction s
