Visualization of Railway Transportation Engineering Management Using BIM Technology under the Application of Internet of Things Edge Computing

Abstract

In the past, railway line planning usually required engineers to design based on their own experience after a series of field visits, leading to heavy workload and low efficiency. Moreover, operation and maintenance management is more complicated due to an abundance of railway station equipment. Based on the above problems, this paper first puts forward the railway transportation line planning and design method based on Building Information Modeling (BIM) technology. Besides, LocaSpace Viewer realizes the three-dimensional (3D) visual scene modeling of the railway environment to improve the efficiency of railway line planning and design. Secondly, the railway station’s visual operation and maintenance management system is constructed via BIM Technology. Besides, the Internet of Things (IoT) is combined with edge computing and deep learning technology to build a 3D model of station equipment, collect data in real time, and analyze data efficiently. Finally, the design effect of the model, the performance of the visual management system, and the test results of network transmission delay are displayed and analyzed. The results show that BIM can construct the 3D visualization model with high fidelity for the railway environment. This model can get a reasonable line planning scheme and analyze its feasibility, provide a reliable basis for engineers to plan railway transportation lines, and improve design efficiency. In addition, the GPU occupation rate, CPU occupation rate, and memory occupation rate of the operation and maintenance management system in different operating environments are within the standard range; when multiple clients access the system, the system data access delay is 100% less than 8 ms, which has good performance. Furthermore, the performance of the IoT transmission data real-time scheduling model and the edge computing optimization algorithm applied to this system is better than other popular methods, which can significantly improve the operation efficiency of the system. This study aims to enhance the efficiency of railway transportation line planning and station operation and maintenance management with the help of digital technologies.

Case Study of Remodelling the As-Built Documentation of a Railway Construction into the BIM and GIS Environment

“…The real innovation lies in the creation of a plug-in that allows extrapolation directly from the design program to the computational model, which then simulates the proposed transport structure in a real context. The project of using BIM in conjunction with the Internet of Things (IoT) is described in [41]. It is an efficient planning and design of rail transport lines with 3D visualization and scenic modeling of the railway environment.…”

Building Information Modeling (BIM) Application for a Section of Bologna’s Red Tramway Line

“…The study was carried out concerning indicators such as clarity of design solutions, number of conflicts, quality of work, control/predictability of costs, requests for changes, etc. The results showed that BIM resulted in 38.5% quality improvement, 38.5% conflict reduction, 61.5% clearer design, 23.1% fewer changes and 30.8% more accurate cost estimates [19,20]. However, the management of I-BIM is affected by considerable constraints linked to the single geometry that makes up the various infrastructure elements, hence the lack of standardization of products [21].…”
