基于模糊推理的列车完整性判别方法研究

Study of Train Integrality Detection Technology Based on Fuzzy Reasoning

在铁路运输中,安全和高效始终是其发展的重要目标。在列车运行安全保障方面,列车完整性检测具有重要意义和作用。为此设计实现了列车完整性检测预警系统,并对其检测条件进行分析,进而提出了一种基于模糊推理的列车完整性检测判别方法:由列车首尾设备采集的定位信息计算得到列车计算车长,然后通过测量得到列车首部和尾部的速度信息和列车制动风管处的状态信息,并按照模糊推理系统的通用流程对这3个参数进行处理,最后利用对应的模糊控制规则进行计算,得到列车完整性的判断结果。研究结果表明:在实际搭建的系统中,该方法用于列车的完整性判别是切实可行的。

The safety and efficiency remain to be two and Train Integrity Detection Technology is significant important goals of railway transportation in safeguarding train operation. We design and realize a train integrity detection and pre-alarming system and analyze its detection conditions. Furthermore, we propose a judgment method of Train Integrality detection based on fuzzy rea soning, which involves three parameters, the length of train calculated by the position informa tion of the head and tail of the train, the velocity of the train, and the state data of train braking air duct pressure. The three parameters are processed using a general-purposed process of fuzzy inference system and calculated by the corresponding rules to conclude the results of train integri ty. It was shown through test that the method is feasible in train integrality detection.
