The Method of Building Engineering Information Model of Railway and Urban Rail Transit Station

Abstract

The invention relates to a method for creating a post engineering information model for a railway and urban railway traffic station. Rail traffic engineering construction involves a plurality of fields and has complex links and a large amount of information, the entire process is perfected continuously with the addition and optimization of all engineering information, and the requirement on total planning of the entire process is high. The method comprises the following steps: making a single functional department create an information model of the department and establish a working set of the department; gathering the working sets of all departments onto the same working platform by sharing elevation and a shaft screen to integrate into a project working set; embedding plant feature information, design information and construction information into a system to form completion data for an operator; gradually separating the information, and constructing task flow in real time according operation for loading and outputting; and releasing cache after finishing output, and recording a log file. According to the method, various types of relevant information in a project are integrated reasonably through a parameter information model, and the created information model is shared and transmitted in a full life cycle process, so that the engineering progress is effectively optimized.

Description

technical field [0001] The invention belongs to the technical field of informationization of railway and urban rail transit, and in particular relates to a method for creating an engineering information model behind a railway and urban rail transit station. Background technique [0002] BIM theory (BIM, Building Information Modeling, Building Information Modeling) has been successfully applied in the construction industry at home and abroad, but it is basically not involved in the railway and urban rail transit industry. [0003] Engineering optimization is subject to three constraints: information, engineering complexity, and engineering cycle. Reasonable optimization results cannot be made without accurate information. The information model not only needs to provide the inherent and actual information of the project, including geometric information, physical information, rule information, etc., but also must provide the actual information after the structure changes, that ...

Problems solved by technology

However, BIM only involves the classification and storage of engineering information by functional departments, and the integration of information from all functional departments to form the engineering data model of the entire project. Only using the BIM workflow cannot realize the project in the later stage of railway and urban rail transit. The separation, call and dynamic loading of information by station operation, the huge database established in the early stage and the huge amount of information modification in the later stage all put forward higher performance requirements for storage media and processors. As the amount of data continues to increase, will seriously affect the running speed
