BIM-based three-dimensional equipment monitoring method and system

The invention provides a BIM-based three-dimensional equipment monitoring method and system. The BIM-based three-dimensional equipment monitoring method includes the steps of generating a three-dimensional BIM monitoring model of equipment to be monitored, wherein the three-dimensional BIM monitoring model comprises a three-dimensional BIM model of a civil engineering structure and a three-dimensional BIM model of the equipment to be monitored in the three-dimensional BIM model of the civil engineering structure, so that the specific position of the equipment to be monitored in the civil engineering structure can be known more directly; using an information terminal local area network for monitoring the working state of the equipment to be monitored, and displaying the corresponding working state information on the three-dimensional BIM model of the equipment to be monitored according to the monitored working state of the equipment to be monitored. In this way, the working state of theequipment to be monitore
