The embodiment of the invention provides a rail transit vehicle-mounted state detection device. A current change curve of alternating current received by the electric locomotive in a target driving interval is segmented according to an electric transmission record between the electric locomotive and a contact line to obtain each group of curve sections, a slope change weight value of each group ofcurve sections is determined, the first transmission information and the second transmission information are derermined from the electric transmission record and the first transmission information and the second transmission information are copied to a train state detection thread. When the thread node corresponding to the train state detection thread has the harmonic interference configuration parameter, the first transmission information and the second transmission information are detected according to the train state detection thread to obtain a detection result. Thus, when the electric locomotive passes through the target driving interval, the detection result used for representing the vehicle-mounted state of the electric locomotive can be accurately determined according to the electric transmission record and the real-time change state of the transmitted alternating current, and then the vehicle-mounted state of the electric locomotive is effectively detected.
本发明实施例提供了一种轨道交通车载状态检测装置,能够根据电力机车与接触线之间的电力传动记录对电力机车在目标行车区间内接收到的交流电的电流变化曲线进行分段得到每组曲线段并确定出每组曲线段的斜率变化权重值,并从电力传动记录中确定出第一传动信息和第二传动信息并拷贝至列车状态检测线程。在列车状态检测线程对应的线程节点存在谐波干扰配置参数时根据列车状态检测线程对第一传动信息和第二传动信息进行检测得到检测结果。如此,能够在电力机车通过目标行车区间时根据电力传动记录以及输送的交流电的实时变化状态准确确定出用于表征电力机车的车载状态的检测结果,进而对电力机车的车载状态进行有效检测。
