Digital engineering management method and system based on BIM technology

The invention discloses a digital engineering management method and system based on a BIM technology, and relates to the field of data processing, and the method comprises the steps: building a basic BIM model based on the BIM technology; based on the engineering conflict analysis topology layer, conflict feature recognition is carried out on the basic BIM model, and a target conflict feature recognition result is obtained; obtaining an optimized target construction scheme based on the engineering conflict management map and the target conflict feature recognition result; uploading the optimized target construction scheme to a digital engineering management platform to obtain engineering operation information and a real-time engineering field video; performing anomaly analysis based on the engineering management model to obtain an engineering anomaly analysis result; and obtaining an engineering abnormity early warning signal based on the engineering abnormity analysis result.
