Operation and maintenance management system based on BIM

The invention discloses an operation and maintenance management system based on BIM, and specifically relates to the technical field of BIM management. The system comprises a BIM operation and maintenance management platform and a GIS monitoring system. The BIM operation and maintenance management platform is connected with the GIS monitoring system, a BIM model and GIS monitoring data are integrated, and monitoring and positioning of municipal engineering and concealed engineering are realized. Through integrating and connecting the BIM operation and maintenance management platform and the GIS monitoring system, and the monitored normal data is updated to the BIM model, so that the design parameters, the working state, the maintenance record and the maintenance path of the BIM model can be checked in real time. The three-dimensional position of the BIM model corresponding to the abnormal data is quickly positioned by the positioning navigation module, and the abnormal data is quicklynavigated to a problem po
