In the above embodiment of the present invention, the analysis of the spatial coding needs to be performed by means of "classification of building information model and coding standard", among others. The building information model classification and coding standard is a national standard with the number of GB/T51269-2017, and a classification method and a coding principle of the building information model are defined in the standard. For example, when describing the space unit entity of a conference room, the space code should include standard classification codes 12-12.10.20 according to the national standard requirement. A space type dictionary table should be defined on the space cloud platform, a mapping relation between a space type and a standard classified code is maintained in the dictionary, when the space coding type is analyzed, the space unit type of the member can be judged through character string matching, and if the space unit type is matched with the space unit type, digital entities of the space unit can be directly created in an information system after inherent attributes (such as longitude and latitude, height and the like) in the BIM member are obtained.

Alternatively, for BIM models that do not define spatial coding that conforms to the GB/T51269-2017 standard, an attempt can be made to match spatial cell types by analyzing custom service attributes of the BIM building blocks. If the service attribute of 'parking space' appears in the customized service attribute, the space type dictionary table can be mapped into a standard 'parking space in an indoor parking lot' or 'parking space in an outdoor parking lot' space unit type according to the condition that the current component is indoors or outdoors. Under the condition of lacking of standardized information support, the matching process is complex and diverse, and the artificial intelligence model can be trained in a supervised learning mode to assist in identifying the space units and the equipment.

Optionally, the equipment manufacturer may burn the equipment identity into the firmware, provide the firmware for the constructor, and update the firmware to the BIM model equipment manufacturer, wherein the equipment manufacturer may apply for the equipment identity information in batch from the internet of things cloud platform in advance, burn the equipment identity information into the intelligent hardware firmware in advance, and then provide the equipment identity information for the constructor. The construction side can take the equipment identity information as the service attribute of the BIM model component, maintain the BIM model, and directly establish the relation between the space unit and the equipment according to the hierarchical relation between the components when the BIM model is introduced to the BIM cloud platform, so that the position information of the equipment is solidified, the equipment can directly obtain abundant space attributes including the position on the space cloud platform after being installed and networked, the equipment position can be quickly positioned by utilizing outdoor navigation or an indoor map, and 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 meets the national standard GB/T51269-2017, the space unit is automatically created in the information system, and the workload of manually creating and maintaining the space unit in the large-scale park information system is reduced; by expanding the component types of the BIM model, adding the user-defined equipment types and adding the pre-burned equipment identity information into the user-defined service attributes, the effects of real-time rendering and equipment state displaying of the BIM model can be perfectly realized, and the spatial equipment relationship can be automatically established and maintained on the Internet of things cloud platform through the hierarchical relationship of the model components.
