| Zusammenfassung: | A speed control device that controls a speed of a train using a tacho-generator includes a calculating unit that calculates, when a pulse count signal obtained by conversion from an AC voltage signal that is outputted from the tacho-generator and corresponds to a rotating speed of a wheel of the train cannot be detected, a first speed using notch information, route data, and car characteristic data and calculates, when the pulse count signal can be detected, a second speed using the pulse count signal. The speed control device includes a position calculating unit that calculates a position of the train using the speed calculated by the calculating unit. |
