Steel structure engineering capital early warning management system based on BIM (Building Information Modeling)

[0027] The present invention will be further described below in conjunction with the drawings.

[0028] Such as figure 1 As shown, a BIM-based steel structure project capital early warning management system includes a data input module, a data collection module, a financial statistics module, a central processing module, an intelligent early warning module, and a data display module;

[0029] The data input module is used to provide BIM model and engineering basic metadata entry, including basic data of BIM model components, comprehensive unit prices for processing of different component types, and comprehensive unit prices for installation. The comprehensive unit prices are calculated on the basis of weight, and according to the goals of the implementation stage, The requested goods plan and installation plan data are formulated on the provided BIM model, and the data is associated and matched to the corresponding components of the BIM model through virtual mapping technology;

[0030] The data collection module is used for the transmission and processing of steel structure progress metadata, generates RFID mobile tags with unique "identity" characteristics of steel components based on the basic metadata of the BIM model, and sends the steel structure delivery and installation progress metadata through the wireless identification terminal Transfer to the central processing module;

[0031] The financial statistics module is used to provide financial internal personnel with data ports related to factory processing progress actual collection and on-site installation progress actual collection, and to transmit fund calculation metadata to the central processing module;

[0032] The central processing module is used for engineering basic metadata mining and analysis. The basic metadata transmitted by the data input module, data collection module, and financial statistics module executes calculation instructions according to predetermined rules. The instructions are divided into three categories, one is The actual output value calculation rules for processing, the other is the actual installation output value calculation rules, and the last one is the installation plan fund calculation rules, where the actual processing output value calculation rules are based on the delivery progress metadata multiplied by the comprehensive unit price of processing corresponding to different component types ; The actual installation output value calculation rule is the installation progress metadata multiplied by the comprehensive installation unit price corresponding to different component types; the installation plan fund calculation rule is the component installation plan corresponding to the current time multiplied by the installation comprehensive unit price corresponding to the different component types. And send the calculation result to the intelligent early warning module and the data display module;

[0033] The intelligent early warning module is used to judge the calculation results of the central processing module’s funds in accordance with the target capital risk early warning mechanism, and to determine the actual delivery, installation and processing receipts through the controllable coefficient of safe funds based on indicators established by the factory and construction site. The output value and the actual output value of the installation are safely compared. If the fund management safety limit is not reached, an early warning event will be automatically triggered, and different early warning plans will be formed. For example, the corresponding factory stops production and processing, and the site stops construction.

[0034] The data display module is used to accurately classify and group the capital calculation results of the central processing module to form corresponding capital real-time grouping reports, including factory capital operation reports and on-site capital operation reports. The factory capital operation reports consist of the actual output value of processing and The factory's actual collection curve is composed, and the on-site accounts receivable report is composed of the actual installation output value, the actual installation payment and the installation plan collection.

[0035] Combine figure 2 As shown, a BIM-based steel structure engineering fund early warning management system and method includes the following steps:

[0036] Step 1: Upload the BIM model of the steel structure in the system and enter the basic data of the component;

[0037] Step 2: Enter the comprehensive unit price for processing and installation of different component types in the system, and the comprehensive unit price is calculated based on weight;

[0038] The third step: According to the goals of the implementation phase, the project department formulates the purchase plan and installation plan data on the BIM model provided;

[0039] The fourth step: The factory produces steel components according to the order plan, and pastes RFID mobile tags with unique "identity" characteristics on the finished components, and scans them for storage;

[0040] Step 5: The factory personnel transmit the steel structure shipment data to the central processing module of the system through the wireless identification terminal;

[0041] Step 6: The system executes calculation instructions on the data collected from the factory. According to the target capital risk early warning mechanism, the actual delivery payment amount and the actual processing output value are safely compared. If the actual processing output value is greater than the actual delivery payment amount multiplied With the controllable coefficient of index safety funds, an early warning is triggered and processing is stopped;

[0042] Step 7: During the on-site steel structure installation, on-site scanners scan the labels on different component types and upload installation progress data;

[0043] Step 8: According to the target fund risk early warning mechanism, the system safely compares the actual installation payment amount with the actual installation output value. If the actual installation output value is greater than the actual installation payment amount multiplied by the index safe fund controllable coefficient, an early warning is triggered. Stop construction;

[0044] The ninth step: The system performs accurate classification and grouping according to the system calculation results, and forms corresponding capital real-time grouping reports, including factory capital operation reports and on-site capital operation reports.

[0045] The specific implementation of the present invention has been introduced above. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
