Web lightweight method for railway four-electric engineering BIM model

Abstract

The invention relates to a railway four-electricity engineering BIM model Web lightweight method, which comprises the following steps: establishing a standard unit library based on a railway four-electricity BIM model, and respectively carrying out model attribute definition and establishing a corresponding unit model library; all the professional standard unit models are subjected to railway four-electricity engineering BIM model general building; after classification, different lightweight optimization schemes are used according to different classes, and SIM data files are generated; the method comprises the following steps: constructing a Web lightweight platform by using a Three.js technology, reading an SIM data file, and displaying a railway four-electricity engineering model on Web,thereby realizing detection of key feature information of the railway four-electricity engineering model on the Web lightweight platform. Lightweight processing is performed on the railway four-electric BIM model file through the BIM lightweight plug-in, geometric information and attribute information are extracted from the model data at the same time in the processing process, then deep optimization is performed on the display content through the instantiation technology, and the loading efficiency and fluency are ensured.

Description

technical field [0001] The invention belongs to the technical field of rail transit engineering information management, and in particular relates to a web lightweight method for a BIM model of a railway four-electric project. Background technique [0002] Rail transit is a complex system integrating multiple disciplines and types of work. It is usually composed of rail routes, stations, vehicles, maintenance bases, power supply and transformation, communication signals, command and control centers, etc., involving lines, stations, bridges, Tunnel, locomotive, vehicle, power supply, communication, signal, electromechanical equipment and fire protection system and many other majors. Four electrical engineering includes communication, signal, electric power and electrification, mainly focusing on equipment. These devices are mainly installed on the line, collectively referred to as trackside equipment, or installed in dedicated machine rooms and various operating houses. Tech...
