The embodiment of the invention provides a space-time fitting conversion method for rail transit pantograph-catenary alarm positioning, and the method comprises the steps: determining a first alarm time point and the operation speed of a vehicle according to the obtained pantograph-catenary alarm time and the operation data of the vehicle; processing the first alarm time point and the running speed by adopting a window function and a speed integral to obtain an average value and a time difference of the running speed corresponding to the first alarm time point; and according to the average value of the operation speed and the time difference, an increment distance is determined, and the increment distance is used for determining position information of an alarm event. According to the method provided by the embodiment of the invention, accurate space-time conversion of the rail transit pantograph-catenary alarm event can be realized, and line operation and maintenance work can be better carried out, so that the alarm processing efficiency and accuracy are improved.

    本申请实施例提供一种轨道交通弓网告警定位的时空拟合换算方法,包括:根据获取的弓网告警时间和车辆的运行数据,确定第一告警时间点和车辆的运行速度;采用窗口函数和速度积分,对所述第一告警时间点和所述运行速度进行处理,得到所述第一告警时间点对应的运行速度的平均值和时间差;根据所述运行速度的平均值和所述时间差,确定增量距离,所述增量距离用于确定告警事件的位置信息。通过本申请实施例的方法,能够实现对轨道交通弓网告警事件的精确时空换算,更好地进行线路的运营和维护工作,从而提高告警处理的效率和准确性。
