铁路货车事故演练系统开发与评估

Development and Evaluation of Railway Freight Car Accident Drill System

基于我国铁路运输安全现状,以及已经发生过的一些铁路货车事故,开发一套基于铁路货车事故的演练系统,其主要功能是铁路货车事故场景模拟、安全知识学习和职工培训测试。系统基于Unity3D开发工具开发,结合多个插件和软件进行辅助开发。根据不同的使用需求,系统可应用于不同的场景,如可以作为培训资料的使用,也可以进行事故场景的模拟,引导职工学习事故应急救援方法,也可以作为独立的考试系统,对职工进行考核。利用系统可用性量表(SUS)和李克特5分量法对系统的可用性进行评估,评估结果表明:在新设计的交互方式支撑下,铁路货车事故演练系统具有良好的可用性,各个终端在不同的应用场景具有各自优势和协同配合能力。系统展现在整个铁路系统事故应急演练中推广应用的潜力。

Based on the current situation of railway transportation safety in China and some railway freight car accidents that have occurred,a train accident-based training system is developed.Its main functions are scene simulation of railway freight car accidents,safety knowledge learning and staff training and testing.The system is developed based on Unity3D development tool,and assisted by several plug-ins and software.According to different needs,the system can be used in different scenarios.For example,it can be used as training materials,can also simulate accident scenarios,guide workers to learn emergency rescue methods,and can also be used as an independent examination system to assess employees.The usability of the system is evaluated by System Usability Scale(SUS)and Likert 5-component method.The evaluation results show that the railway freight train accident drilling system has good usability under the support of the new interactive design.Each terminal has its own advantages and cooperation ability in different application scenarios.The system shows the potential of popularization and application in the whole railway system emergency drill.
