If the advantages of the ETCS are to be used for greater route utilisation, it is critical to know whether a vehicle was moved during the shut-down phase. The retrofittable axle encoder with integrated Cold Movement Detection function from Lenord + Bauer acquires movements of the wheel axle in the de-energised state and supplies assured position information immediately after the login. Thanks to the batteryless operation, the position remains reliably stored for more than 72 hours. If no movement was detected, the train can return to route operation immediately with a valid position. This removes the need for a slow, time-consuming start so that the position can be reliably determined at the next balises, significantly reducing the time required to return the rail vehicle to operation.
The robust axle encoders from Lenord + Bauer have proven their worth in the rail industry for decades. They are now being coupled with the Cold Movement Detector to form a customised encoder system. The contactless, magnetic measuring system and the battery-free operation enable long-lasting use in the toughest of ambient conditions.
