智能轨道车辆安全信息的情景感知集成与传输
Situation-Aware Integration and Transmission of Safety Information for Smart Railway Vehicles
摘要：
近年来，铁路训练的发展趋势主要体现在高速化、信息化、娱乐化、智能化等方面，特别是行车高速化趋势突出，几个技术发达国家之间的高速竞争日趋激烈。为了实现高速，发动机或电动机分布在训练的多个车辆上以提供增加的动力，而单个发动机或电动机主要用于传统列车。速度的提高和更复杂的动力系统自然会导致更高的大规模事故的机会。从这个角度来看，在事故发生之前进行主动安全控制的重要性再怎么强调也不过分。为了实现主动安全控制，需要对从物联网传感器获得的安全信息进行情境感知集成和传输。关键物联网传感器的类型取决于情境条件。因此，安全信息的集成和传输应该与物联网传感器一起执行，以提供适合于所面临情况的安全信息。这篇简短的论文旨在设计一种如何操作物联网传感器网络的方法，以实现铁路车辆的主动安全控制，并提出一种基于队列管理的介质访问控制方案。
英文摘要：
Recent trend of railway train development can be characterized in several aspects : high speed, infortainment, intelligence in driving, and so on. In particular, trend of high speed in driving is prominent and competition for high speed amongst several techno-savvy countries is becoming severe. To achieve high speed, engines or motors are distributed over multiple vehicles of train to provide increased motive power, while a single engine or motor has been mostly used for conventional trains. Increased speed and more complicated powertrain system naturally incur much higher chance of massive accidents. From this perspective, importance of proactive safety control before accident takes place cannot be over-emphasized. To implement proactive safety control requires situation-aware integration and transmission of safety information obtained from IoT sensors. Types of critical IoT sensors depend on situational conditions. Thus, integration and transmission of safety information should be performed with IoT sensors providing the safety information proper for faced situation. This brief paper is to devise a methodology how to operate IoT sensor network enabling proactive safety control for railway vehicles and to propose a queue management based medium access control scheme.
