The invention discloses a vehicle running direction identification method and system, and the method comprises the steps: employing a vehicle bogie (axle box) temperature wireless real-time monitoring mode, and enabling the system to collect the temperature data of all bogie (axle box) monitoring points with the same installation conditions (position, height, installation surface, installation mode and installation technology) in real time; based on a statistical analysis conclusion of vehicle bogie (axle box) temperature monitoring data, in a normal condition or an ideal condition, in the vehicle running process, the vehicle running direction is taken as a reference, and the temperature of a rear axle box monitoring point of the same bogie (B0) is higher than that of a front axle box monitoring point corresponding to the same bogie (B0); the system compares the temperature data of the monitoring points corresponding to the front and rear shafts of each bogie and judges the running direction of each bogie; the system integrates the real-time judgment results of the running directions of all bogies or part of the bogies of the vehicle, can distinguish power bogies from non-power bogies by adopting a weighting mode, and can give the running direction of the vehicle by integrating the working conditions of the vehicle and the states of the bogies, thereby realizing the real-time identification of the running direction of the vehicle; according to vehicle bogie (axle box) temperature wireless real-time monitoring data, the system continuously recognizes and updates the running direction of each bogie, then the running direction of the vehicle is given, and real-time dynamic recognition of the running direction of the vehicle is achieved.

    本发明公开了一种车辆运行方向识别方法和系统,采用车辆转向架(轴箱)温度无线实时监测方式,系统实时汇聚安装条件(位置、高度、安装面、安装方式、安装工艺)相同的各个转向架(轴箱)监测点的温度数据;基于对车辆转向架(轴箱)温度监测数据的统计分析结论,正常情况下或理想情况下,在车辆运行过程中,以车辆运行方向为参考,同一转向架(B0)后轴轴箱监测点温度高于前轴轴箱对应监测点温度;系统比对各转向架前后轴对应监测点的温度数据,判断各转向架的运行方向;系统综合车辆所有转向架或部分转向架运行方向的实时判定结果,采用加权方式,可区分动力转向架和非动力转向架,并可综合车辆工况和转向架状态,给出车辆运行方向,实现车辆运行方向的实时识别;依据车辆转向架(轴箱)温度无线实时监测数据,系统持续识别并更新每个转向架运行方向,进而给出车辆运行方向,实现车辆运行方向的实时动态识别。
