The construction side can use the equipment identity information as the business attribute of the BIM model component, maintain the BIM model, when the BIM model is imported to the BIM cloud platform, the relation between the space units and the equipment can be directly established according to the hierarchical relation among the components, so that the position information of the equipment is solidified, the equipment can directly acquire rich space attributes including the position on the space cloud platform after being installed and connected to the network, and the equipment position can be quickly positioned by utilizing an outdoor navigation or an indoor map, so that the equipment maintenance workload of a property management company is greatly simplified.

According to the technical scheme, the space type of the BIM model component is automatically identified by analyzing the space code which accords with the national standard GB/T51269-2017, and the space unit is automatically created in the information system, so that the workload of manually creating and maintaining the space unit in the information system of the large-scale park is reduced; by expanding the component types of the BIM model, adding the self-defined equipment types, and adding pre-burnt equipment identity information into the self-defined service attributes, the effect of real-time rendering and displaying the equipment states of the BIM model can be perfectly achieved, and the spatial equipment relationship can be automatically created and maintained on the Internet of things cloud platform through the model component hierarchical relationship.
