Claim 0:
1. A railroad equipment state determination apparatus, comprising:
a storage that stores a plurality of operation data associated with one cycle of a prescribed operation performed by railroad equipment, wherein the one cycle of the prescribed operation is that the railroad equipment driven by a motor from a stopped state performs a switching operation, and then comes into the stopped state again;
an evaluation criteria setting section that sets evaluation criteria based on the plurality of operation data stored in the storage; and
a determination section that determines whether new operation data resulting from one cycle of the prescribed operation newly performed by the railroad equipment is abnormal based on the evaluation criteria, wherein
the operation data includes data of drive transition information indicating drive information of the motor at each timing during the prescribed operation,
the evaluation criteria setting section sets statistic transition information that indicates transition of statistics determined by statistically computing the drive information at each timing during the prescribed operation as one of the evaluation criteria, based on the drive transition information included in the operation data, and
the determination section performs:
calculating transition of a degree of abnormality relating to the new operation data by comparing the drive transition information included in the new operation data with the statistic transition information at each timing during the prescribed operation;
calculating a total degree of abnormality by synthesizing the transition of the degree of abnormality; and
determining whether the new operation data is abnormal based on the total degree of abnormality.
