Fremgangsmåde til positionsdetektering til skinneköretöjer

摘要

The system includes a memory block (1) in which there is stored each journey, divided into sections identified by their theoretical absolute position parameters, length and radius and in which the correction curves are stored. At least one recording unit sensitive to travel in a curve and a relative position recorder, send signals to a control unit. The control unit uses these signals to establish the variation profile of the actual correction curves parameters. The control unit undertakes an adjustment based upon achieving the minimum error in the profiles of coordinates obtained using the theoretical parameters and the actual parameters, determining the absolute real position of the vehicle. The recording unit may be a sensor for measuring the turning velocity in a bend of the vehicle and the relative position recorder may supply information to measure the variation of the position of the vehicle and its absolute speed in the direction of travel. #CMT#USE/ADVANTAGE : #/CMT# Can be used in train tilt control system. Allows to correct errors in detected train position caused by e.g wheelslip, skidding, wear of sensors.
