Abstract

The device has a transponder system e.g. radio frequency identification system, stationarily attached to a transport network at a fixed position and a vehicle retrieving data stored in the transponder system by a mobile transmission and reception unit. The reception unit determines an allocation due to the data stored in the transponder system over the place, at which the transponder system is attached. A signal of the transponder system contains and exact position of the system, so that the vehicle determines its position an ordinal number or other allocation characteristics of the system.

Description

The The invention relates to a device for locating and localization of vehicles operating on a route network.

to Location and location are different in the prior art Methods and devices known.

So In particular, the location where a vehicle is located may be over Number of revolutions of his wheels be determined. A counter counts the Turns of a wheel and by means of the known circumference of the wheel This can be done by the Route and by means of a known starting point the position of the vehicle can be determined on a route. It is disadvantageous However, here are the wheels subject to wear and tear thus the circumference of a wheel decreases with increasing duration of use. Furthermore, wheels have wheels Slip on, i. The distance traveled by the vehicle is shorter than the counter determined. Therefore, this method is relatively inaccurate and requires from time to time a synchronization by means of known intermediate points.

such Intermediate points are particularly important for rail vehicles so-called hectometer tables, i. Tafeln at the edge of the track, the Train drivers in (two-) hundred meters distance indicate the position on the track.

Farther the location of a vehicle can be determined by means of GPS, wherein the vehicle is equipped with a corresponding GPS receiver. It is disadvantageous However, GPS signals are not available everywhere, so in particular in terrain cuts, Tunnels or laterally densely wooded routes provide a location and Localization not possible is.

It It is therefore an object of the invention to provide a device with a location and localization of vehicles on one Route network operate quickly and without great effort is made possible.

These The object is in connection with the preamble of claim 1 according to the invention the features specified in claim 1 solved.

The under claims include advantageous embodiments the solution of the invention Claim 1.

According to the invention, transponder systems are which in particular passively executed are, or comparable components to funkabfragbaren position indication in the route network for advantageous use in the inspection and Maintenance distributed.

transponder In particular, passive elements are activated via suitable radio signals and return coded information if necessary. They are beneficial very small (mm to cm) and inexpensive to produce (cent range at big Quantities, RFIDs).

At the Passing or driving on equipped routes are over carried simple Transmitter system activates the transponder and the technical space characterizing associated Data / information (route information) read out. The read out Information is basis for a fast, easy and secure location and automatic Zuscheidung detected findings to the respective technical places of Infrastructure.

Conceivable is also such systems for easy support of the exact, network-bound Location of rail vehicles as part of the inspection (CBCT also rule trains) to use. That At significant, precisely measured locations become funkabfragbare Transponder placed with coded local information, the with the transmitting and receiving units of the accordingly equipped inspection / measuring / control vehicles can be queried and with the local path and route information to an improved Locate the vehicles on the railway network.

By a simple and secure location and localization of individual components and systems of infrastructure the effort for significantly reduce the inspection and maintenance as well as one significantly higher data quality to reach.

Especially Advantageous are passive transponder systems, in particular RFIDs (Radio Frequency Identification), as used e.g. for localization of goods in the field of logistics.

• – das Signal des Transponders die genaue Position des Transponders enthält und somit das Fahrzeug hieraus direkt seine Position ermitteln kann und/oder
• – eine Ordnungsnummer oder andere Zuordnungsmerkmale des Transponders zusammen mit der genauen Position des Transponders in einer Datenbank abgespeichert sind, die Datenbank auch auf dem Fahrzeug abfragbar ist und das Fahrzeug anhand der Datenbank seine Position ermittelt und/oder
• – die Transponder fortlaufend nummeriert sind und in gleichbleibenden Abständen voneinander entfernt angeordnet sind.

If a vehicle (inspection / maintenance vehicle, locomotive, regular train) with a transponder or its resonant frequency tuned transmitting and receiving unit from the route network, so at the points where a transponder unit is attached, from the targeted transponder a response signal ( coded with feature / route data). The location is thus located and the vehicle can calculate its position by

• - The signal of the transponder contains the exact position of the transponder and thus the vehicle can determine directly from this position and or
• - An ordinal number or other assignment features of the transponder are stored together with the exact position of the transponder in a database, the database is also interrogated on the vehicle and the vehicle based on the database determines its position and / or
• - The transponder are numbered consecutively and are arranged at equal distances from each other.

• – Streckenkilometer und Richtung bzw. Richtungsgleis, z.B. Streckenkilometer 125,3 und Richtung bzw. Richtungsgleis nach Hamburg und/oder
• – als geographische Ortsangabe wie geographische Länge und Breite, z.B. 54° 12,6' Nord und 010° 17,8' Ost und/oder
• – als fortlaufende Nummer wie z.B. 1.1, 1.2, 1.3, ... und/oder
• – in Form von Auffälligkeiten der Geographie oder der Strecke, wie z.B. Brücken, Abzweigungen oder Haltestellen.

The position of the transponder can be contained in the transponder or the database, in particular in the form of

• - distance kilometer and direction or direction track, eg kilometer 125.3 and direction or direction track to Hamburg and / or
• - as a geographical location such as latitude and latitude, eg 54 ° 12,6 'north and 010 ° 17,8' east and / or
• - as a serial number such as 1.1, 1.2, 1.3, ... and / or
• - in the form of abnormalities of geography or the route, such as bridges, junctions or stops.

The Application of the device according to the invention However, it is not limited to rail systems only. Much more can she for all Types of vehicles are used on specified route networks and thus at certain specified locations within the Pass the route network.

So can in vehicles of road traffic Transponder systems according to the invention be integrated into the road, so that advantageously also determined can be on which lane the vehicle is running.

The Invention will be explained in more detail with reference to an embodiment.

In the particularly advantageous embodiment Transponders are distributed along the route. A vehicle with a tuned to the transponder or its resonant frequency Transmitting and receiving unit moves along the corresponding section of the route. In the place, at If a transponder has been attached to the track, it will be replaced by the targeted transponder issued a response signal. Thus, the Localized and the vehicle can determine its position.

Advantageous becomes such a system for accurate location on railway networks in combination with simple incremental based position sensing systems used in which over the number of recorded wheel revolutions determines the track position becomes. In this case, the incremental position determination is sufficient short distances through the over the transponder synchronized track data synchronized and possible, due to the purely incremental position detection resulting deviations reduced. Existing jumps in the continuous track kilometry (kilometer jump) can thereby both in the acquisition and analysis of track-relevant Data taken into account simply and safely become. Through a track- and route-selective coding of the transponder is a secure location and position determination in densely branched Route networks reached.
