Security method and security system for a railway network
A protection method for a railway network which is divided into track sections by track elements, and which can be traveled on by vehicles. The vehicles request steps for assignment from selected track elements to form travel path elements. In order to optimize the train service, each of the selected track elements provides at least one signal for each vehicle that requests at least one of the steps for assignment as a travel path element from same. A protection system for a railway network is configured to carry out the protection method.
1. A protection method for a rail network that is divided by track elements into track sections and on which vehicles can travel, the method comprising:
requesting, by a respective one of the vehicles, from at least one of the track elements an input that is used to assign the at least one track element as a route element;
the input being selected from the group consisting of:
an authorization of the at least one track element as the route element for the respective vehicle;
a registration of the at least one track element as the route element for the respective vehicle; and
a marking of the at least one track element as the route element for the respective vehicle;
receiving, by the respective vehicle, at least one signal from the at least one track element;
wherein the at least one signal for the respective vehicle is specified by the at least one track element, and the at least one track element specifies a type, a position, and a status of the at least one signal for the respective vehicle;
specifying the at least one signal at a braking target point and:
if the braking target point is a danger point, specifying the at least one signal as a virtual main signal; and
if the braking target point is not a danger point, specifying the at least one signal as a virtual target signal.
2. A protection method for a rail network that is divided into track elements and on which vehicles can travel, the method comprising:
receiving a request, by at least one of the track elements from one of the vehicles being a requesting vehicle, for inputs that are used to assign the at least one of the track elements as a route element;
the inputs being selected from the group consisting of:
an authorization of the at least one track element as the route element for the requesting vehicle,
a registration of the at least one track element as the route element for the requesting vehicle, and
a marking of the at least one track element as the route element for the requesting vehicle;
specifying, by the at least one track element, at least one signal of the at least one track element for each input;
specifying, by the at least one track element, a type, a position, and a status of the at least one signal;
specifying, by the at least one track element, the at least one signal at a braking target point, and
specifying, by the at least one track element, the at least one signal as a virtual main signal if the braking target point is a danger point, and as a virtual target signal if the braking target point is not a danger point.
3. A protection system for a rail network that is divided by track elements into track sections and on which vehicles can travel, the system comprising:
at least one of the track elements being configured to receive a request from one of the vehicles for inputs that are used to assign the at least one track element as a route element, the one of the vehicles being a requesting vehicle;
the inputs being selected from the group consisting of:
an authorization of the at least one track element as the route element for the requesting vehicle,
a registration of the at least one track element as the route element for the requesting vehicle, and
a marking of the at least one track element as the route element for the requesting vehicle;
said at least one track element being configured to:
specify at least one signal of the at least one track element for each input;
specify a type, a position, and a status of the at least one signal;
specify the at least one signal at a braking target point, and
specify the at least one signal as a virtual main signal if the braking target point is a danger point, and as a virtual target signal if the braking target point is not a danger point.
