Station yard construction cost accounting method based on electronic archives

The invention discloses a station construction cost accounting method based on electronic archives, which mainly divides all costs into two categories, namely material costs and service costs, respectively performs targeted accounting processing, digitalizes station construction information in a form of building a 3D model for the material costs, and obtains the material costs and the service costs; equipment and pipeline data for generating station construction are extracted from digital information and then bound with corresponding prices, the total material cost amount is obtained through rapid calculation, service cost is associated with construction procedures, adaptive calculation is conducted with the procedures as segmentation nodes, and therefore the total service cost amount is obtained; according to the method, the total cost of various stations is calculated, then the total cost is bound with station scene elements, the calculation mode is optimized and updated by comparing the total cost with the
