Verfahren und Einrichtung zur Erfassung der Beschleunigung eines mehrgliedrigen Schienenfahrzeuges

摘要

The method involves fitting two different units (FK, FS) with acceleration sensors (S1, S2) with their outputs connected to an on board computer. Initialisation is carried out with the vehicle on a track having a known gradient profile and the profile being referred to the track e.g. stored in the computer as a sequence of equidistant points on the track and the related rail gradient values. The actual positions of the sensors is either communicated to the computer per input or to vehicle mounted receivers located at the height of the sensor from a track side transmitter as the vehicle passes. After the journey commences the gradient at the location of the sensor (S1) in the forward direction is continually calculated from the measured acceleration values (a1(t), a2(t)) of both sensors and the stored track gradient of the rear sensor in the direction of travel (S2). The vehicle acceleration is taken into consideration in these calculations and saved for the continued storage of the profile at specified distances along the track together with the specific track location.
