Abstract

Die Erfindung betrifft ein Verfahren zur Feststellung und Bewertung von Störungen im Fahrzeug-Fahrweg-System innerhalb des Eisenbahn-Regelbetriebs, wobei ein, auf allen Fahrzeugen des Regelbetriebs installiertes Mess- und Auswertesystem, unzulässige Störungen im Zusammenwirken von Fahrzeug und Fahrweg feststellt, diese auf einen Server des Bahnbetreibers überträgt, eine dort installierte AnalyseSoftware die Ursache (Mängel am Fahrzeug und/oder am Fahrweg) der Störung feststellt, und die zuständige Stelle für Instandsetzung automatisch, online über das mangelhafte Verhalten des Fahrzeugs bzw. der störenden Stelle am Fahrweg informiert.Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu entwickeln, das im laufenden Bahnbetrieb, ohne zusätzliche Messfahrzeuge, Störungen im Zusammenwirken von Fahrzeug und Fahrweg zeitnah feststellt und bewertet, dabei möglichst alle, auf das Gesamtsystem wirkende Einflüsse, berücksichtigt und, wenn erforderlich, die zuständige Instandsetzungsstelle automatisch online über den Störfall unterrichtet.Dies wird erfindungsgemäß dadurch erreicht, dass ein, auf dem Fahrzeug installiertes Mess- und Auswertesystem die Beschleunigungen des Fahrzeugs in lateraler, vertikaler und longitudinaler Richtung, die GPS-Position, die Fahrzeuggeschwindigkeit, das Datum und die Uhrzeit mit einer vorgegebenen, wählbaren Abtastrate erfasst, die Beschleunigungsüberlagerung in lateraler und vertikaler Richtung, sowie die Beschleunigungsüberlagerung im Raum, aus der gemessenen lateralen, vertikalen und longitudinalen Beschleunigung, berechnet und die gemessenen und berechneten Beschleunigungen bewertet. Im Fall, dass eine Beschleunigungsgröße ihre vorgegebene Störschwelle (Beschleunigungsgrenzwert) überschreitet, wird der entsprechende Messdatensatz zusammen mit den berechneten Beschleunigungsüberlagerungen online, verschlüsselt auf einen Server des zuständigen Bahnbetreibers übertragen und dort automatisch analysiert, um festzustellen, ob die Ursache der Störung vom Fahrzeug oder Fahrweg ausgeht.The invention relates to a method for determining and evaluating disruptions in the vehicle-track system within regular railway operations, whereby a measuring and evaluation system installed on all vehicles in regular operations detects unacceptable disruptions in the interaction between vehicle and track and reports them The railway operator's server transmits, an analysis software installed there determines the cause (defects in the vehicle and/or the route) of the disruption, and the responsible body for repairs is automatically informed online about the defective behavior of the vehicle or the disruptive area on the route The invention is based on the object of developing a method that promptly detects and evaluates disruptions in the interaction between vehicle and route during ongoing railway operations, without additional measuring vehicles, while taking into account all influences affecting the entire system and, if necessary, the responsible one The repair center is automatically informed online about the incident. According to the invention, this is achieved in that a measuring and evaluation system installed on the vehicle records the accelerations of the vehicle in the lateral, vertical and longitudinal directions, the GPS position, the vehicle speed, the date and the time recorded with a predetermined, selectable sampling rate, the acceleration overlay in the lateral and vertical directions, as well as the acceleration overlay in space, is calculated from the measured lateral, vertical and longitudinal acceleration, and the measured and calculated accelerations are evaluated. In the event that an acceleration quantity exceeds its specified disturbance threshold (acceleration limit value), the corresponding measurement data set together with the calculated acceleration overlays is transmitted online, encrypted, to a server of the responsible railway operator and is automatically analyzed there to determine whether the cause of the disturbance is from the vehicle or route goes out.
