The invention relates to a subway vehicle state real-time evaluation method based on online monitoring data. The method comprises the following steps: 1) acquiring vibration acceleration data of all tunnel walls in one day; 2) calculating the maximum Z vibration level VLZ, max of the vibration acceleration signal of the tunnel wall; (3) the tunnel wall vibration acceleration data correspond to a train operation timetable, and the maximum Z vibration level of tunnel wall vibration caused by each train is obtained; 4) determining the screening value of the maximum Z vibration level numerical value of the tunnel wall vibration of each monitored section; 5) counting the frequency anami of each train exceeding the screening value of each monitoring section within one day, and calculating the corresponding single-day probability prnum; 6) continuously monitoring and counting tunnel wall vibration acceleration data in multiple days, and calculating a train vehicle state index VSINum value, and 7) evaluating the vehicle state based on the train vehicle state index VSINum value.

    本发明涉及一种基于在线监测数据的地铁车辆状态实时评估方法,包括:1)获取一天内所有的隧道壁振动加速度数据;2)计算隧道壁振动加速度信号的最大Z振级VLZ,max;3)将隧道壁振动加速度数据与列车运营时刻表对应,获得每一列车所引起隧道壁振动的最大Z振级;4)确定每个监测断面隧道壁振动最大Z振级数值的筛选值;5)统计出各列车一天内超出每个监测断面所述筛选值的频次anum_i并计算出相应的单天概率pr_num;6)连续监测和统计多天内的隧道壁振动加速度数据,并计算列车车辆状态指数VSI_num值,7)基于列车车辆状态指数VSI_num值评价车辆状态。
