The real-time working condition production analysis method based on domestic BIM according to claim 1 is characterized in that: When the S7 receives the security risk detection results, it automatically triggers the early warning mechanism immediately, sends risk alert information to the management terminal, and automatically displays the specific analysis results and indicator parameters of the security risk in the sent security risk monitoring report. At the same time, according to the risk type and degree, combined with historical data and professional knowledge base, it automatically generates correction suggestions.

10. A real-time working condition production analysis system based on domestic BIM, implementing a real-time working condition production analysis method based on domestic BIM as claimed in any one of claims 1 to 9, characterized in that: include: Data acquisition module: by installing construction monitoring equipment at the construction site to collect real-time working condition data and environmental data of the construction site, the BIM model is associated with the construction monitoring equipment data, and the collected real-time working condition data and environmental data are transmitted to the data processing module; Data processing module: used to process the collected real-time working condition data and environmental data, combine the real-time working condition data and environmental data with the BIM model, perform data fusion processing, and transmit the fused real-time working condition data and environmental data to the working condition production analysis module and the production progress analysis module; Working condition production analysis module: By statistically analyzing the integrated real-time working condition data and environmental data, the structural deformation impact index, equipment operation status deviation index, energy consumption deviation index and environmental quality factor are obtained, and the status of the BIM model is updated according to the analysis results; Production progress analysis module: used to analyze and identify the deviation status of the actual construction progress. By comparing the actual construction progress with the planned progress in the BIM model, the progress deviation identification index is obtained. Working condition safety assessment module: Based on the working condition production analysis results and production progress analysis results, it conducts a comprehensive analysis of working condition safety risks, calculates the working condition comprehensive safety risk assessment coefficient, and transmits the working condition safety risk analysis results to the safety risk detection module; Safety risk detection module: detects the safety risk of working conditions by comparing the comprehensive safety risk assessment coefficient of working conditions with the comprehensive safety risk threshold of working conditions; Early warning feedback module: used to provide early warning feedback on detected security risk results, automatically generate a security risk monitoring report based on the security risk analysis process, and give security risk correction suggestions and send them to the management terminal.
