Abstract:

[Problem] To provide a railway vehicle state monitoring device that is capable of performing determination easily without requiring much time and effort to adjust parameters for determining a vehicle state, such as the presence/absence of abnormalities in a railway vehicle. [Solution] This railway vehicle state monitoring device 100 comprises: a detection device 1 that detects vehicle information represented by e.g. the wheel load of wheels 31 of a railway vehicle 3 traveling on a track; and a determination device 2 including a classifier 21 to which the detected vehicle information is input, and that outputs a vehicle state, such as the presence/absence of abnormalities in the railway vehicle. The classifier is created by employing machine learning such that, by employing, as teaching data, the vehicle information of a railway vehicle for which the vehicle state is known and said vehicle state, said known vehicle state is output when the vehicle information is input.
