In this scheme, all the basic models are loaded first, for example, the house model, beam-making platform, beam storage platform, beam lifting machine, lifting frame, mixing station, transport vehicle, silo, beam transport vehicle and other basic models are loaded first. When the production of beams is located at different nodes, the production information of the beam field is collected through the Internet of Things system, etc., and the information includes the status information of the corresponding components and the process information, production data information, location information, and identity information. Based on the production information of the beam yard, the corresponding model is retrieved from the BIM component library, copied to the corresponding position of the 3D geographic information GIS model, and the position of the loaded component model is updated based on the production information to achieve real-time, visualization, and visualization purposes.

Specifically, when the process changes, for example, the steel bar binding model is changed from the steel bar binding model to the semi-finished beam model; if the initial tensioning is completed, the semi-finished beam model is changed to the finished beam model; the position change causes the model change to only involve the finished beam: When the position of the finished beam changes, such as the beam moving operation, it is transferred from one pedestal to another pedestal.

Combining the above process (when the process information and position information of the beam change), the beam model on the original pedestal is cleared, the new model is copied from the component library to the corresponding position, and the production information of the original corresponding component model is attached to the in the new component model.

The three-dimensional geographic information GIS model constructed in this embodiment can simulate the real scene of the beam field and the geographical environment in which it is located, making the display of the spatial information of the beam field more intuitive. Each location point in the beam field corresponds to each other. During specific implementation, by selecting key points, the coordinates of each key point in the 3D geographic information GIS model are correspondingly associated with the coordinates of each key point in the beam field, ensuring that each key point in the real beam field is relative to the geographic The spatial positional relationship of the environment is consistent with the spatial positional relationship of the corresponding key points in the three-dimensional geographic information GIS model relative to the geographical environment in the model. The basic model and component model are associated with the infrastructure, tooling equipment, pedestal, personnel, and components in the beam yard, and the collected beam yard production information drives the copying of the corresponding model from the BIM model library to the corresponding position, visually displaying the The on-site beam prefabrication and tooling equipment operation dynamics in the beam yard are convenient for visual management and control.
