Abstract
The invention relates to a method for controlling the sequence of trains during traffic control, whereby a telephone communication between a traffic controller in a traffic control centre and a driver is carried out. In order to increase security during telephone communication, the traffic controller transmits a driving permit to the driver, in addition to a test code which is specific to the driving permit and determined by a traffic control computer, and the driver inputs the driving permit and the test code into a vehicle appliance which calculates the test code according to the same algorithm as the traffic control computer, and compares the calculated test code with the inputted test code. The driving permit is authenticated only if the two codes correspond.
Claims5
A method for controlling the sequence of trains during traffic control, with communication taking place between a train controller in a train control center and a locomotive engineer, wherein the train controller transmits movement permission to the locomotive engineer and a movement-permission-specific checking code, which is determined by a train control computer, and the locomotive engineer enters the movement permission and the checking code in a vehicle appliance which uses the same algorithm as the train control computer to calculate the checking code, and compares the calculated checking code with the entered checking code, with the movement permission being confirmed only in the event of a match, and rejection of the movement permission being signaled if there is no match;
- and
- wherein the locomotive engineer transmits to the train controller a train running message, which is required in order to release a track section, and a checking code which is determined by the vehicle appliance and is specific to the train running message, and the train controller enters the train running message and the checking code in the train control computer, which uses the same algorithm as the vehicle appliance to calculate the checking code and compares the calculated checking code with the entered checking code, and the track section is released only in the event of a match.
A method for controlling a sequence of trains during traffic control, the method which comprises:
- determining, with a train control computer using a given algorithm, a movement-permission-specific checking code;
- transmitting, from a train controller to a locomotive engineer, a movement permission and the movement-permission-specific checking code;
- entering the movement permission and the checking code in a vehicle appliance, calculating the checking code in the vehicle appliance with the given algorithm to form a calculated checking code, and comparing the calculated checking code with the entered checking code;
- confirming the movement permission only in the event of a match, and signaling a rejection of the movement permission if there is no match;
- and
- transmitting a running message and an associated checking code from the locomotive engineer to the train controller, with the train running message being required in order to release a track section and the associated checking code being determined by the vehicle appliance and being specific to the train running message;
- entering the train running message and the associated checking code in the train control computer, using the same algorithm as the vehicle appliance to calculate a calculated checking code, and comparing the calculated checking code with the entered checking code;
- and
- releasing the track section only in the event of a match between the calculated checking code and the entered checking code.
