A Multi-person collaborative Simulation System for Subway Emergency Based on Virtual Reality

Abstract

In the operation of urban rail stations, joint emergency drills for different types of work are an important way to ensure the safe operation of urban rail stations. However, due to the lack of equipment and means, at present, the joint emergency drills for urban rail stations are mostly a single-person system. Based on the current status of emergency joint drills in urban rail stations, this article proposes a virtual reality-based multi-person collaborative urban rail station emergency simulation system. Construct a large-scale virtual reality scene through the viewpoint-related LOD quadtree, and use socket technology to achieve multiplayer online interaction. Finally, all models are jointly driven by Unity3d in the simulation scene. An immersive, multi-industry coordinated urban rail station emergency drill simulation system was constructed. Providing a simulation training environment similar to the actual situation for emergency trains in urban rail stations can greatly improve the shortcomings of difficult and inefficient implementation of the organization, and change the difficult situation of insufficient emergency drills for multiple types of rail stations.

Multi-person interaction in collaborative virtual conference for Metaverse

“…The framework layer is used to specify the functions of the multi-person collaborative virtual conference system [19]. This system includes three frameworks: virtual human framework, virtual environment framework, and interaction and collaboration framework.…”

An Emergency Measure Completeness Evaluation Method Based on UGC Data

“…Sun [16] built a fuzzy evaluation model by the fuzzy comprehensive evaluation method to evaluate and analyze the overall quality of Xi'an subway fire emergency plan. Chen et al [17] proposed an emergency simulation system of multiperson cooperative urban rail station based on virtual reality, which can improve the problem of insufficient emergency response. Although costs are saved by constructing an evaluation index system and simulation method, the data sources are relatively weak.…”
