走行部作为城轨列车的关键部件,其服役状态对列车运行安全起着至关重要的作用。目前,中国城轨列车走行部实时监测系统尚在起步阶段,且多数集中在轴箱监测,监测功能单一。研究并设计一套城轨列车走行部地面检测系统,针对轮对尺寸、车底关键部件异常及轴箱、电机等部件温度异常具有检测报警功能,此外还具备系统自检、自动防护、测轴计速和车号识别读取的辅助功能。系统实现了对城轨列车走行部关键零部件的通过式检测,并能针对检测结果做出故障预警。该系统已在北京地铁9号线投入使用,对现有列车检修工作起到很好的支持作用,对城轨列车在途监测的实现具有指导意义。

As a key component of metro vehicles, the reliability of running gears is important for ensuring the safety of train operations. At present, the real-time monitoring system for metro vehicle running gears in China is still in its infancy, and most of them focus on axle box monitoring with a single monitoring function.This paper develops a detection system for running gears of metro vehicles, which has the function of detecting and alarming the abnormality of the wheelset size, the key parts of the vehicle bottom and the abnormal temperature of the axle box, motor and other parts. In addition, it has auxiliary functions include system self-test, automatic protection, axle speed measurement, vehicle number identification and reading.The pass-type detection of key components of the running gear is realized, then fault diagnosis can be achieved through the detection information and failure alarm will be given. The system has been put into use in Beijing Metro Line 9 and has performed well in supporting vehicle maintenance work.
