The invention provides a train integrity detection method and device, and the method comprises the steps: carrying out the segmented comparison processing of a continuous track bed vibration signal, obtaining an effective track bed vibration signal, carrying out the matched filtering and testing of the continuous track bed vibration signal according to basic information and the effective track bed vibration signal, and obtaining a train integrity detection result. A real-time positioning result of the effective ballast bed vibration signal is obtained; when the running state of the train is normal running, determining a first measurement area number occupied by the train according to a real-time positioning result; when the running state of the train is departure acceleration or arrival deceleration, the historical data of the preset measuring areas of the track are backtracked, the real-time position of the train head and the real-time position of the train tail of the train are obtained, and the number of second measuring areas occupied by the train is determined according to the real-time positioning result, the real-time position of the train head and the real-time position of the train tail; and according to the first measurement area number or the second measurement area number, the integrity of the train in the train running state is judged, and an integrity judgment result is obtained. According to the invention, the technical problem of determining the integrity of the train is solved.
本发明提供了一种列车完整性检测方法及装置,包括:对连续道床振动信号进行分段比较处理,得到有效道床振动信号,并根据基本信息和有效道床振动信号对连续道床振动信号进行匹配滤波和测试,得到有效道床振动信号的实时定位结果;当列车行驶状态为正常行驶时,根据实时定位结果,确定列车占用的第一测区数;当列车行驶状态为出站加速或进站减速时,对轨道预设测区的历史数据进行回溯,得到列车的车头实时位置和车尾实时位置,并根据实时定位结果、车头实时位置和车尾实时位置,确定列车占用的第二测区数;根据第一测区数或第二测区数对列车行驶状态下列车的完整性进行判断,得到完整性判定结果。本发明实现了对列车的完整性进行确定的技术问题。
