Control of rail vehicles
View Patent ↗A decentralized control of rail vehicles that run in alternating directions on a single-track route, e.g., between two train stations by way of an exclusive right (token). A storage device is arranged at each end of the route, for instance an RFID unit. Only a single exclusive right exists for the route. The exclusive right is either stored in one of the two storage units or carried along by a rail vehicle that is traveling on the route. In the latter case, an additional rail vehicle is effectively prevented from traveling on the route, because none of the storage units can provide the exclusive right, which is being transported between the storage units by the rail vehicle and is occupied by the rail vehicle. The novel concept creates an efficient possibility of decentralized train protection and thus can be implemented significantly more economically than existing centralized train safety approaches.
1. A method for controlling rail vehicles, the method comprising:
providing a first storage device adjacent one end of a line section and a second storage device adjacent an opposite end of the line section;
storing an exclusive right of way on the line section into the first storage device and ensuring that the exclusive right of way on the line section is not stored on the second storage device;
reading the exclusive right of way on the line section from the first storage device by a rail vehicle and placing the first storage device in a state in which the first storage device can provide no exclusive right of way on the line section; and
wherein the rail vehicle stores the exclusive right of way into the second storage device shortly before leaving the line section, shortly after leaving the line section or upon leaving the line section.
2. The method according to claim 1 , wherein the line section is a single-track line section.
3. The method according to claim 2 , wherein the storage devices are disposed at the ends of the single-track line section.
4. The method according to claim 1 , wherein the first storage device and the second storage device have an RFID tag, and the exclusive right of way corresponds to at least one predefined value or signal of the RFID tag.
5. The method according to claim 1 , which comprises, for entering and driving on the line section, reading the exclusive right of way is read from the first storage device and storing the exclusive right of way by the rail vehicle.
6. The method according to claim 5 , which comprises, when the exclusive right of way has been read out, marking the exclusive right of way as invalid, overwritten, reset or deleted in the first storage device.
7. The method according to claim 1 , wherein the rail vehicle has a communication device for reading from and writing to the first and the second storage device.
8. The method according to claim 1 , which comprises braking the rail vehicle on entering the line section if the rail vehicle has not obtained the exclusive right of way.
9. The method according to claim 1 , wherein the exclusive right of way comprises a signal, a token, a value, or an item of information.
10. The method according to claim 1 , which comprises executing and processing the exclusive right of way and/or operations involving the exclusive right of way with data protection.
11. The method according to claim 1 , which comprises displaying a state of the first storage unit and/or of the second storage unit relating to an availability of the exclusive right of way.
12. A rail vehicle, comprising:
a communication device for communicating with a first storage device adjacent one end of a line section and a second storage device adjacent an opposite end of the line section;
said communication device being configured to read an exclusive right of way on a line section from the first storage device, and wherein the first storage device can be placed in a state in which the first storage device cannot provide an exclusive right of way on the line section; and
said communication device being configured to pass the exclusive right of way to the second storage device, to thereby place the second storage device in a state in which the second storage device is enabled to provide the exclusive right of way on the line section.
13. The rail vehicle according to claim 12 , comprising a monitoring device configured to carry out a predetermined action if the rail vehicle enters the line section without having obtained an exclusive right of way.
14. The rail vehicle according to claim 13 , wherein the monitoring device is configured to issue a warning and/or initiate a braking operation.
