摘要

应急处置是火车站确保安全的关键环节。这就需要实施应急预案模拟和具有成本效益的沉浸式演练。在本文中,我们将一系列事件处置纳入应急流程,并对人员、物资和设备进行建模,以创建多种应急场景。此外,我们还介绍了一种基于数字孪生的多场景应急解决方案。该解决方案在信息空间中完全还原了车站的关键组成部分,并提供了一种身临其境的应急处置方式。解决方案中使用的四维模型可模拟车站并与之互动,它由客运站物理实体、多场景应急虚拟实体、数字孪生连接和应急孪生服务等细节组成。利用该模型构建了火灾、自然灾害(如洪水、地震)、社会安全事件、公共卫生事件等多场景应急事件的数字孪生。该解决方案在中国京张高铁清河站进行了测试。利用清河站的实际运营数据,我们验证了多场景应急演练,模拟了相应的应急处置预案,并从真实世界模拟的逼真度、多应急场景的覆盖范围和用户友好性三个方面对所提出的解决方案进行了评估。评估结果表明,建议的解决方案得分较高,达到了系统可用性量表的可接受水平。

Digital twin for multi-scenario emergency of railway passenger stations

Emergency disposal is a critical aspect for railway stations to ensure safety. This requires the implementation of emergency plan simulations and cost-effective immersive drills. In the paper, we incorporate a set of disposals for events into emergency processes and model the personnel, supplies, and equipment to create multiple emergency scenarios. Additionally, we introduce a digital twin-based solution for multiple scenarios of emergencies. This solution completely restores the key components of a station in the information space and provides an immersive way for emergency disposals. The four-dimensional model used in the solution simulates and interacts with the station, and it is composed of the details of passenger station physical entity, multi-scenario emergency virtual entity, digital twin connection, and emergency twin service. The digital twin for versatile emergency events such as fire disaster, natural disaster (e.g., flood, earthquake), social security incident, and public health event have been constructed using the model. The solution was tested at Qinghe, a station during Beijing-Zhangjiakou high-speed railway in China. By utilizing the actual operation data of Qinghe, we validated the multi-scenario emergency drills, simulated the corresponding emergency disposal plans, and assessed the proposed solution from three aspects: the fidelity of the real-world simulation, coverage of the multiple emergency scenarios, and the user-friendliness. The evaluations indicate that the proposed solution attains good score and the acceptable level of system usability scale.
