The invention provides a track multi-source data alignment method, a track multi-source data alignment device and a track system. Feature points in a time domain signal of a reference monitoring device correspond to an event that a preset part of a train passes through the reference monitoring device; therefore, the accurate reference time point when the predetermined part of the train passes through the reference monitoring device can be quickly and accurately obtained, so that the accurate time point when the predetermined part of the train passes through each general monitoring device can be calculated according to the reference time point and the known distance between the monitoring devices, and the corresponding time translation amount is obtained; therefore, automatic time domain alignment of multi-source monitoring data can be realized, time alignment processing can be carried out without manual operation, the alignment precision is higher, time domain alignment of a large amount of data can be automatically realized for an actual track monitoring scene provided with a large amount of sensors, and timely and efficient track monitoring big data analysis can be realized.
本发明提供一种轨道多源数据对齐方法、装置及轨道系统,其中,由于将基准监测装置的时域信号中的特征点与列车的预定部位经过基准监测装置这一事件对应起来,因此能够快速准确地得到列车的预定部位经过基准监测装置的精确的基准时间点,从而能够根据基准时间点以及各监测装置之间的已知间距推算出列车的该预定部位经过各一般监测装置的准确时间点,得出相应时间平移量,进而能够实现多源监测数据的自动时域对齐,不需要人工操作进行时间对齐处理,不仅对齐精度更高,而且对于设置有大量传感器的实际轨道监测场景,能够自动实现大量数据的时域对齐,从而可实现及时高效的轨道监测大数据分析。
