The invention discloses a subway vehicle operation quality monitoring system and a monitoring method thereof. The monitoring system comprises trackside detection equipment, a field control center and a remote control center, the field control center is in communication connection with the trackside detection equipment and the remote control center. The trackside detection equipment comprises an acquisition unit array, a ground AEI antenna and a wheel sensor, the acquisition unit array is an optical fiber sensor array, the optical fiber sensor array is provided with a plurality of optical fiber sensors which are continuously and uniformly distributed in a track, the plurality of optical fiber sensors have known intervals, and a single wheel on a train runs on the optical fiber sensor array; therefore, the single wheel can be dynamically monitored by using the optical fiber technology. According to the invention, the optical fiber sensor measurement technology is utilized to dynamically measure the wheel rail acting force and overload and unbalance loading caused by the wheel rail out-of-roundness of the metro vehicle and the tread damage generated at the wheel rail contact position, and the running state is monitored, so that the running safety of the train is effectively guaranteed.

    本发明公开了一种地铁车辆运行品质监测系统及其监测方法,所述监测系统包括轨旁检测设备、现场控制中心和远程控制中心;现场控制中心与轨旁检测设备和远程控制中心分别通信连接。轨旁检测设备包括采集单元阵列、地面AEI天线、车轮传感器,采集单元阵列为光纤传感器阵列,光纤传感器阵列设为多个光纤传感器连续均匀分布在轨道中,多个光纤传感器具有已知的间距,列车上的单个车轮在该段光纤传感器阵列上行驶,即可绕该单个车轮一周,则针对该单个车轮利用光纤技术完成动态监测。本发明利用光纤传感器测量技术,动态测量地铁车辆的车轮不圆度和轮轨接触位置产生的踏面损伤引起的轮轨作用力,超偏载,及运行状态的监控,有效保障列车的运行安全。
