摘要

自由市场迫使基础设施运营商提高运营效率。为了实现这一目标,除其他事项外,必须减少人事成本。这意味着要减少火车站检查员的人数。由于他们还负责检查过往列车的故障状态,列车未被观察到的运动距离越远,发生重大事故的风险就越大。另一方面,用于检测上述列车故障状态的新型传感器系统也有许多发展。不幸的是,所有这些系统都只关注单个或至少几个偏离正常的特定偏差,并且是完全独立的解决方案。在较高的通过速度下,这些系统的精度和可靠性在很大范围内变化。这是当今故障检测传感器系统仅用于报警有人驾驶列车引导站的重要原因。考虑到这些趋势,对整体火车检查系统的需求是显而易见的,并导致了一个名为“检查站”的研究项目,该项目由奥地利政府资助。我们的方法是基于获取所有相关列车属性来获得完整列车状态的知识,以便更好地进行故障估计。因此,开发了一种有效集成商用传感器系统和通用数据处理的概念。它支持通过基于规则的机制轻松配置数据分析和定义故障状态。该系统的主要技术创新来自于通过控制系统直接连接到联锁系统,该系统提供了在检测到故障(例如停止列车)的情况下自动干预的能力。为了确定新型传感器系统在实际条件下的可靠性,建立了一个检测点的原型,并集成了最相关的传感器系统(热箱探测器、平轮探测器、动态秤和载荷计探测器)。将进行广泛的测试,以证明该系统的功能。

New development of an overall train inspection system for increased operational safety
The free market forces infrastructure operators to increase their operational efficiency. To achieve this, among other things personnel costs have to be reduced. This implicates the reduction of the number of train station inspectors. Since they were also responsible for checking the passing trains for fault states, the higher distances of unobserved movement of trains result in higher risks of heavy accidents. On the other hand, there were numerous developments of new sensor-systems for checking the mentioned train fault states. Unfortunately, all of these systems focus only on singular or at least on several particular deviations from normal and are completely stand-alone solutions. At higher passing speeds the accuracy and the reliability of these systems varies in a wide range. This is an important reason why today's fault-checking sensor systems are only used for alarming manned train guidance stations. Taking these trends into account, the demand for an overall train inspection system is obvious and resulted in a research project called "Checkpoint", which is funded by the Austrian government. Our approach is based on the acquisition of all relevant train properties to get knowledge of the complete train condition for better failure estimation. Thus, a concept for efficient integration of commercially available sensor systems and for universal data treatment was developed. It enables easy configuration of the data analysis and definition of fail-states by a rule based mechanism. The main technical innovation of the system comes from the direct connection to the interlocking system via the control system, which offers the ability to intervene automatically in case of a detected failure (e.g. stopping the train). To determine the reliability of new sensor systems under realistic conditions a prototype of a Checkpoint was built up and the most relevant sensor systems (hot box detector, flat wheel detector, dynamic scale and loading gauge detector) were integrated. Extensive testing would be performed to prove the functionality of the system.
