DERAILMENT SIGN DETECTION SYSTEM AND DERAILMENT SIGN DETECTION METHOD

The pitch angular velocity of a truck and the roll angular velocity of the truck which have been detected by an angular velocity sensor (5) provided in a train in order to detect the pitch angular velocity and roll angular velocity of the traveling train are stored in a memory (32), the predicted va...

Beschreibung
Zusammenfassung:	The pitch angular velocity of a truck and the roll angular velocity of the truck which have been detected by an angular velocity sensor (5) provided in a train in order to detect the pitch angular velocity and roll angular velocity of the traveling train are stored in a memory (32), the predicted value of the roll angular velocity after a lapse of a predetermined time is calculated on the basis of the history of the roll angular velocity, when the pitch angular velocity of the truck, which has been detected by the angular velocity sensor, and the predicted value of the roll angular velocity exceed preset threshold values, respectively, a derailment sign of the train is determined, and when the derailment sign is determined, the derailment sign is reported to the outside.
