Abstract
A collected-current monitoring device includes a current-value obtaining unit for obtaining current values I1 and I2; a first RMS-calculation unit for calculating a root mean square (RMS) 1 of the current value I1 at a window width W; a second RMS-calculation unit for calculating a root mean square (RMS) 2 of the current value I2 at the window width W; a determining unit for determining whether a combination of the RMS 1 and the RMS 2 satisfies an abnormality condition; an abnormality-signal output unit for outputting an abnormality signal when the abnormality condition is satisfied; an information-obtaining unit for obtaining railway vehicle information; and a setting unit for setting a set-parameter that includes at least one of the window width W or the abnormality condition depending on the railway vehicle information.
