NEUER MAGNETKOPF UND VERFAHREN ZUM PROGRAMMIEREN UND ABTASTEN MAGNETISIERBARER TRAEGER UND ZUM MESSEN DES SICHERHEITSABSTANDES UND DER GESCHWINDIGKEIT VON FAHRZEUGEN

摘要

A magnetic transducer is designed to produce an alternating magnetic field on a section of railway track. The recording is followed by automatic scanning and the information related to speed to ensure safe distances between trains. Two pole discs (1) are mounted on a common shaft (3) that is supported on a bearing bracket (6) secured to the vehicle. The pole discs are free to rotate on a length of track (7). A winding (2) is located between the pole discs and slip rings (4, 5) are inset into the bracket. A magnetic field is set up across the rail and this alternates over specific length of track determined by the excitation frequency.
