Abstract

This sensor state determination system (50) is a sensor state monitoring system that is capable of accurately determining whether or not a detection sensor used with a railroad vehicle is in an abnormal state and is equipped with: a detection sensor (51) capable of detecting a physical value acting upon the railroad vehicle (1); and an electronic control device (60). A monitoring sensor (52) equivalent to the detection sensor (51) is installed at a position equivalent to the position where the detection sensor (51) is installed. The electronic control device (60) is provided with a determination means (coherence computation unit (62) state determination unit (63)) that computes on the basis of a first signal (X) detected by the detection sensor (51) and a second signal (Y) detected by the monitoring sensor (52) a coherence value (CXY) which indicates a correlation between the signals and determines that the detection sensor (51) is in an abnormal state if said coherence value (CXY) is smaller than a preset abnormality determination value.
