车辆的故障诊断是保证城市轨道交通安全运营的重要措施。介绍目前常见的离线诊断模式和在线诊断模式,比较了它们的特点,并指出其存在的缺陷。研究了基于移动代理技术的列车故障诊断模式,分析了移动代理技术在城市轨道交通列车故障诊断应用中的适应性,以及与现有的故障诊断方式相比所具有的优点。提出了基于移动代理技术的列车故障诊断机制,构建了基于移动代理技术的列车故障诊断参考模型。
Vehicle fault diagnosis is an important measure to ensure the safe operation of urban rail transit. The current common offline diagnosis mode and online diagnosis mode are introduced, their characteristics are compared and their defects are pointed out. This paper studies the train fault diagnosis mode based on mobile agent technology and analyzes the adaptability of mobile agent technology in train fault diagnosis of urban rail transit as well as the advantages compared with existing fault diagnosis methods. A train fault diagnosis mechanism based on mobile agent technology is proposed and a train fault diagnosis reference model based on mobile agent technology is constructed.
