Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Auswertung von auf einem Speichermedium aufgezeichneten Verkehrsdaten gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for evaluating traffic data recorded on a storage medium in accordance with the preamble of claim 1.
Die Verkehrsdatenauswertung dient insbesondere der Gewährleistung der Verkehrssicherheit, indem unerwünschte oder potentiell gefährliche Betriebszustände erkannt werden und somit Maßnahmen für deren Beseitigung getroffen werden können. Die Daten können außerdem zur Optimierung der Strecke genutzt werden. Beispielsweise deuten überdurchschnittlich häufige Zwangsbremsungen an einem bestimmten Punkt der Strecke auf unzureichende Signalisierung einer Langsamfahrstrecke oder eines Haltepunktes hin. Auch individuelle Fahrweisen der Lokführer, beispielsweise hinsichtlich einer Geschwindigkeits-Orts-Kurve, sind auswertbar.The traffic data evaluation serves in particular as a guarantee traffic safety by adding unwanted or potentially dangerous operating conditions are recognized and thus Measures for their elimination can be taken. The data can also be used to optimize the route become. For example, above-average ones indicate Emergency braking at a certain point on the route inadequate signaling of a slow speed route or a breakpoint. Also individual driving styles of the train drivers, for example with regard to a speed-location curve, are evaluable.
Die Auswerteziele setzen eine genaue Zuordnung der Fahrereignisse, beispielsweise Einleitung eines Bremsvorganges, zu einer Position der Fahrstrecke voraus. Es gibt Bestrebungen, die aufgezeichneten Verkehrsdaten um entsprechende Orts-Koordinaten zu erweitern. Nachteilig dabei ist jedoch, dass Ortserfassungssysteme, insbesondere auf satellitengestützter Basis mittels GPS (global positioning system), außerordentlich komplexe Systeme sind, die bei bestimmten Ortsgegebenheiten, insbesondere Gebirge oder Tunnel, nicht überall funktionsfähig sind. Nachteilig ist außerdem, dass für die zeitsynchrone Ortsdatenerfassung ein eigenes Speichermedium oder eine Kapzitätserweiterung des vorhandenen Speichermediums für die Verkehrsdatenerfassung erforderlich ist. The evaluation targets set an exact assignment of the driving events, for example initiation of a braking process, to a Position of the route ahead. There are efforts the recorded traffic data by appropriate location coordinates to expand. However, it is disadvantageous that Location detection systems, especially on satellite-based Base using GPS (global positioning system), extraordinary are complex systems which, given certain local conditions, especially mountains or tunnels, not functional everywhere are. Another disadvantage is that for the time-synchronous Location data acquisition your own storage medium or a capacity expansion of the existing storage medium for Traffic data collection is required.
Der Erfindung liegt die Aufgabe zugrunde, die oben geschilderten Nachteile zu vermeiden und eine gattungsgemäße Vorrichtung zur Auswertung von Verkehrsdaten anzugeben, die sich durch einfachen Aufbau und gute Handhabbarkeit auszeichnet. Dabei ist anzustreben, dass eine Erweiterung der zugseitigen Systeme vermieden wird.The invention has for its object the above To avoid disadvantages and a generic device to evaluate the evaluation of traffic data characterized by simple structure and easy handling. The aim is to expand the train side Systems is avoided.
Erfindungsgemäß wird die Aufgabe mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Die befahrene Strecke wird quasi anhand eines Vergleichs zwischen aufgezeichneten Verkehrsdaten und gespeicherten streckenspezifischen Besonderheiten identifiziert. Diese streckenspezifischen Besonderheiten können beispielsweise ein Geschwindigkeitsprofil und/oder Haltestellenabstände und/oder die Anzahl der Haltestellen und/oder Abstände zwischen ATC (automatic train control)-Koppelspulen am Gleis und/oder deren Anzahl sein. Da diese oder auch andere markante Merkmale der verschiedenen Fahrstrecken des Gleisnetzes sehr unterschiedlich sind und noch weitere Ausschlusskriterien die Anzahl der zu vergleichenden Strecken reduzieren, kann eine Verwechslung ausgeschlossen werden. Relativ dicht benachbarte und genauestens lokalisierbare Ortsmarken, wie beispielsweise ATC (automatic train control)-Koppelspulen ermöglichen eine ausreichend genaue Zuordnung der Verkehrsdaten-Events zu einem bestimmten Ort. Zusätzliche zuginterne Baugruppen sind dabei entbehrlich, sofern die Auswertung zugextern stattfindet. Die streckenspezifischen Besonderheiten müssen nur einmal während einer Testfahrt oder auch während einer regulären Fahrt ermittelt und aufgezeichnet werden.According to the invention the task with the characteristic Features of claim 1 solved. The route traveled quasi based on a comparison between recorded traffic data and saved route-specific features identified. These route-specific features can, for example, a speed profile and / or Stop distances and / or the number of stops and / or distances between ATC (automatic train control) coupling coils on the track and / or their number. This one or other striking features of the different routes of the track network are very different and still further exclusion criteria the number of to be compared Reducing stretches can prevent confusion become. Relatively closely adjacent and precisely localizable Placemarks, such as ATC (automatic train control) coupling coils allow a sufficiently precise assignment traffic data events to a specific location. additional internal train assemblies are not necessary, if the evaluation takes place externally. The route-specific Special features only have to be used once during a test drive or determined during a regular trip and to be recorded.
Gemäß Anspruch 2 werden die streckenspezifischen Daten archiviert und stehen somit als Datenbank in Registern zur Verfügung. Die Vergleichsmittel greifen auf diese Register zu und erkennen in einer Art Überlagerungsprozess zwischen den ermittelten Verkehrsdaten und den gespeicherten streckenspezifischen Besonderheiten sehr schnell eine nur für eine Strecke mögliche Übereinstimmung zwischen den Vergleichsmerkmalen.According to claim 2, the route-specific data are archived and are therefore available as a database in registers. The comparison means access these registers and recognize in a kind of overlay process between the determined Traffic data and the saved route-specific Special features very quickly only for one route possible agreement between the comparison features.
Die Auswertung der aufgezeichneten Verkehrsdaten erfolgt gemäß Anspruch 3 vorzugsweise mittels einer Visualisierung, bei der die Verkehrsdaten den streckenspezifischen Merkmalen überlappend dargestellt werden. Dabei können verschiedene graphische Darstellungen der interessierenden Parameter, z. B. Geschwindigkeitsprofile, oder auch Grenzwertdarstellungen oder Diagramme erzeugt werden.The recorded traffic data is evaluated in accordance with Claim 3 preferably by means of a visualization which overlaps the traffic data with the route-specific features being represented. Different graphic Representations of the parameters of interest, e.g. B. Speed profiles, or limit value displays or Diagrams are generated.
Anspruch 4 charakterisiert eine vorteilhafte Ausführungsform, wobei die Verkehrsdaten auf einen auswechselbaren Datenträger geschrieben werden, welcher nach der Zugfahrt zur Auswertung der aufgezeichneten Verkehrsdaten in der Auswertevorrichtung dient. Es ist aber auch möglich, als Speichermedium einen überschreibbaren Speicher zu verwenden, der dem Schienenfahrzeug zugeordnet ist und dessen aufgezeichnete Daten beispielsweise jeweils nach 1000 km per Datenfunk an eine entsprechende Auswertevorrichtung übermittelt werden. Dabei können die aktuellen Verkehrsdaten nach ca. 1100 km die ältesten Verkehrsdaten überschreiben.Claim 4 characterizes an advantageous embodiment, the traffic data on a removable data carrier be written, which after the train journey for evaluation the recorded traffic data in the evaluation device serves. However, it is also possible to use one as the storage medium rewritable memory to be used by the rail vehicle is assigned and its recorded data, for example every 1000 km via radio to a corresponding one Evaluation device are transmitted. You can the current traffic data after approx. 1100 km the oldest Overwrite traffic data.
Die Erfindung beschränkt sich nicht auf die vorstehend diskutierten Ausführungsbeispiele. Vielmehr ist eine Anzahl von Varianten denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen.The invention is not limited to those discussed above Embodiments. Rather is a number of Variants conceivable, which are also fundamentally different Execution make use of the features of the invention.
