Abstract

A method for determining a signal aspect representing the vacant or occupied state of a track section for a rail vehicle, in particular a maintenance or construction vehicle, on a CBTC track. In this case, the rail vehicle does not have an on-board CBTC device. In order to dispense with special hardware, an app on a smartphone initiates the following steps: A) photographing of a track beacon in the direction of travel, B) determining the ID (identification signature) of the track beacon, C) transmitting of the track beacon ID to a CBTC track control center and D) receiving of the signal aspect determined by the CBTC track control center for the track section starting with the track beacon.

First claim

The invention claimed is:

1. A method of determining a signal aspect representing a vacant or an occupied state of a track section for a rail vehicle, on a communication-based train control track, wherein the rail vehicle does not have an on-board CBTC device, the method comprising:
initiating the following steps with a software application running on a smartphone:
A) photographing a track balise located in a direction of travel of the rail vehicle;
B) determining an identification signature of the track balise;
C) sending the ID of the track balise to a CBTC track control center, wherein the CBTC track control center determines the signal aspect for the track section that starts with the track balise; and
D) receiving the signal aspect determined by the CBTC track control center for the track section starting with the track balise.

2. The method according to claim 1 , wherein the rail vehicle is a maintenance or construction vehicle that is not equipped with an on-board CBTC device.

3. The method according to claim 1 , wherein the step of determining the ID of the track balise comprises reading a track-balise-specific Quick Response code.

4. The method according to claim 1 , wherein the step of sending the track balise ID and the step of receiving the signal aspect are performed by communicating via a public communication network.

5. The method according to claim 1 , which comprises sending the track balise ID in step C), receiving the signal aspect in step D), processing the data by the app and displaying the signal aspect on the smartphone taking safety-related methods into account.

6. A device for performing the method according to claim 1 , comprising:
a software application to be activated by way of a smartphone for determining a track section on which to travel based on a photographically recorded identification signature of a track balise;
said app being configured for requesting a signal aspect of the track section from a communication-based train control track control center.
