Low carbon urban rail transit station city integration based on building information modeling and sensor fusion

In order to better play the role of information technology in the construction management of rail transit projects, we analyze the application of geographic information system (GIS) + building information modeling (BIM) technology in the construction management of rail transit projects by combining the characteristics of GIS+BIM technology and aiming at the overall improvement of project management efficiency and technical management methods. This study is mainly conducted with the support of BIM technology and sensing technology. In the design stage, carbon emissions are classified according to the source activities of building carbon emissions, and the carbon emissions in the building life cycle are quickly calculated by using BIM technology, and the design is optimized according to the analysis of the budget results. The experimental results prove that the low-carbon building evaluation standard cloud model of all-electronic computer interlocking system for urban rail transit established in this study, combined with the comprehensive weighting results, calculates the low-carbon index cloud model and comprehensive cloud model, and derives the operational safety risk level of the all-electronic computer interlocking system, and the model optimization effect is good. Practice shows that GIS+BIM technology can realize the refinement and informatization of construction management, and has a broad development space in the field of urban rail transit and urban underground space construction.
