According to the preamble to claim 1, the invention relates to a protection method for a rail network, which is divided by track elements into track sections and on which vehicles can travel—in which the vehicles request, from selected track elements, steps for assignment as a route element and in which each of the selected track elements is respectively automatically assigned as a route element, under predefined conditions, for each vehicle, which requests the steps for assignment as a route element from it and outputs an assignment confirmation to the respective vehicle.
According to the preamble to claim 7, the invention also relates to a protection system for a rail network, which is divided by track elements into track sections and on which vehicles can travel, in which the vehicles are suitably embodied to request, from selected track elements, steps for assignment as a route element, and in which each of the selected track elements is suitably embodied automatically to assign itself as a route element, under predefined conditions, for each vehicle, which requests the steps for assignment as a route element from it and to output an assignment confirmation to the respective vehicle.
A generic protection method and a generic protection system are, for example, known from Patent DE 44 06 720 C2 and have the advantage that they do not require a central control tower.
It is known that rail networks require regular construction and/or maintenance work that has to be performed by construction site staff known as a gang. A gang has to be protected when working in a danger area of the relevant track segment in which the construction or maintenance work is to be performed.
Known gang warning systems consist of a series of signal lamps and audible alarms, which, following installation at the edge of the track bed of the relevant track segment and on the approach of a vehicle, are to be activated by track marshals. While the gang warning system is active, the gang has to stay away from the danger area of the relevant track segment and allow the approaching vehicle to pass. I.e. information to the effect that a vehicle is approaching the danger area is based on reliable work on the part of track marshals.
The invention is based on the object of better safeguarding construction and/or maintenance work in the danger area of a rail network.
This object is achieved with a protection method with the features of claim 1 in that at least one of the track elements, after its integration into the rail network, forms a working zone and only outputs the assignment confirmation for the respective vehicle after the inputting of an assignment release, wherein the at least one track element is provided with means for release via which the assignment release is input manually.
In the protection method according to the invention, therefore, the working zone is formed with assistance of technological protection measures and can only be traversed by a vehicle for which an assignment of the at least one track element as a route element has been ascertained if the means for release have been manually actuated in advance. The construction site staff, who can identify the ascertainment of the assignment, are therefore, able to leave the danger area of the relevant track segment safely and only then actuate the means for release.
The object is achieved with a protection system with the features of claim 7 in that at least one of the track elements is suitably embodied, after its integration into the rail network, to form a working zone and only to output the assignment confirmation for the respective vehicle after the inputting of an assignment release, wherein the at least one track element comprises means for release via which the assignment release is to be input manually.
Claims 2 to 6 relate to advantageous developments of the protection method according to the invention to which the advantageous embodiments of the protection system disclosed in claims 8 to 12 correspond.
The establishment of a working zone can be organized in a particularly flexibly manner in various ways. For example, according to the teaching of claim 2, it is preferably provided according to the invention that the at least one track element which forms the working zone is temporarily integrated into the rail network between two initially adjacent track elements and removed again therefrom. Accordingly, according to the teaching of claim 8, it is advantageous in device terms for the at least one track element which forms the working zone to be suitably embodied to be temporarily integrated into the rail network between two initially adjacent track elements and removed again therefrom.
Furthermore, according to the teaching of claim 3, it is preferably provided according to the invention that the at least one track element which forms the working zone is provided with means for the determination of its present position and specifies the present location of the working zone between the two track elements in dependence on its present position. Accordingly, according to the teaching of claim 9 it is advantageous in device terms for the at least one track element which forms the working zone to comprise means for the determination of its present position and to be suitably embodied to specify the present location of the working zone between the two track elements in dependence on its present position.
The construction site staff can carry these means for determining the present position of the track element with them. Thus, it is possible for the present location of the established working zone to be continuously adapted to the present location of the construction site staff.
According to the teaching of claim 4, it is considered to be advantageous in method terms if, to request the steps for assignment from respective track element, a vehicle control of the respective vehicle determines requirements and outputs the requirements by means of communication means assigned to the vehicle control to the respective track element. Accordingly, according to the teaching of claim 10, it is considered to be advantageous in device terms if a vehicle control of the respective vehicle is suitably embodied, to request the steps for assignment from the respective track element, to determine requirements and to output the requirements by means of communication means assigned to the vehicle control to the respective track element.
It is further considered to be advantageous in method terms according to the teaching of claim 5 if a track element control of the respective track element, which receives the requirements of the respective vehicle relating to the respective track element by means of communication means assigned to the track element control, uses the received requirements to determine the assignment of the respective track element as a route element for the respective vehicle and outputs the respective assignment confirmation by means of the communication means assigned to the track element control to the respective vehicle. And accordingly, according to the teaching of claim 11, it is considered to be advantageous in device terms if a track element control of the respective track element is suitably embodied to receive the requirements of the respective vehicle relating to the respective track element by means of a communication means assigned to the track element control, to use the received requirements to determine the assignment of the respective track element as a route element for the respective vehicle and to output the respective assignment confirmation by means of the communication means assigned to the track element control to the respective vehicle.
According to the teaching of claim 6 it is also considered to be advantageous in method terms if, in the at least one track element which forms the working zone, the track element control, the means for release and the means for determining the present position are provided as components of a mobile device, which is in particular portable by a person.
Accordingly, according to the teaching of claim 12, it is considered to be advantageous in device terms if, in the at least one track element which forms the working zone, the track element control, the means for release and the means for determining the present position are embodied as components of a mobile device, which is in particular portable by a person.
A device of this kind is easy to carry or operate, for example by the leader of a gang. This enables the leader of gang only to release the passage of a vehicle through the working zone when the entire gang has left the danger area of the working zone on the track.
The invention is described below in more detail with reference to the figures, in which:
A first one 3 of the subsystems is a communication system via which the three further subsystems 4 to 6 communicate with one another.
A second one 4 of the subsystems is formed by track elements S1, S2, . . . , Sp with track element controls TSC1, TSC2, . . . , TSCp, wherein the track elements divide the rail network 1 into a plurality of track sections G1, G2, . . . , Gq. The track elements include, for example, switching devices, track crossings, grade crossings for passengers, bumpers and derailment detectors. However, the track elements also include working zones established to be mobile. In the section shown, initially four track elements S1 to S4 link eight track sections G1 to G8.

The development of the assignment of a track element as a route element for a vehicle and hence the decentralized development of the movement authority for a vehicle takes place via three individual method stages. A first one of these method stages is a route check. A second of these method stages is a route definition. And the third of these method stages is the assignment of the movement authority. These three method stages of the development of the assignment of a track element as a route element for a vehicle are used on the one hand for conflict resolution. On the other hand, they advantageously safeguard loading of the track elements and track sections of the rail network in a manner optimized with respect to demand and usage.
During the route check, the respective vehicle requests a first step for assignment in the form of the entry of an authorization B. To this end, the respective vehicle outputs a request to input the authorization B of the track element as a route element for the vehicle to the respective track element lying in its route. The track element then checks automatically whether it is possible to input this authorization. The track element only prevents the authorization being input if, with respect to the requested input, there is already an entry of an authorization for another vehicle in directly the opposite direction. Otherwise, the respective track element can continue to be used for other vehicles (trains). Therefore, it can output assignments as a route element to other vehicles so that they can use the track element in their own route. If it is possible to input an authorization, the track element makes this entry and then issues confirmation that the authorization has been input to the respective vehicle.
During the route definition, the respective vehicle requests a second step for assignment in the form of the input of a registration R. To this end, the respective vehicle outputs a request to the respective track element lying in its route for the input of the registration R of the track element as a route element for the vehicle. The track element then automatically checks whether it is possible to input this registration. Under predefined circumstances, the track element stops the registration being input. Otherwise, the respective track element can still be used for other vehicles (trains). Therefore, it can output assignments as a route element to other vehicles so that these can use the track element in their own route. If it is possible to input a registration, the track element makes this input and then outputs a confirmation that the registration has been input to the respective vehicle.
On granting of the movement authority, the respective vehicle requests a third step for assignment in the form of the entry of a marking M. To this end, the respective vehicle outputs to the respective track element in its route a request for the marking of the track element to be input as a route element for the vehicle. The track element automatically checks again whether this marking of the registration is possible. Under predefined circumstances, the track element stops the marking being input. If the input of the marking is possible, the track element inputs the marking, initiates, if necessary, the changeover of the track element and then outputs confirmation of the entry of the marking to the respective vehicle. All other vehicles that request the input of a marking have to wait until the marking that has been input is deleted again.
Reception of confirmation of the input of the marking now authorizes the respective vehicle to use the track element as a route element and to advance over the track element into the following track section as far as a predefined point before the next track element, wherein it knows the predefined point from the track topology—i.e. from a topological component of a track atlas. The vehicle also comprises a position-finding system so that it always knows which point in the rail network is its present location.
On passing the track element, the respective vehicle outputs confirmation of passage to the respective track element. On reception of this confirmation of passage, the respective track element deletes the authorization that has been input, the registration that has been input and the marking that has been input.
To carry out the three steps for assignment, each track element control TSCi of the track elements manages memory locations.
In the first embodiment of the protection system according to the invention, the memory locations of the individual track elements in each case form cells of a table Ti, where i=1 to p. The columns in these tables correspond to the different types of loading of the respective track element. For example, the switches shown in each case comprise four types of loading identified in the figures by arrows F1, F2, F3 and F4. Other track elements, such as, for example, entry/exit elements, derailment detectors or working zones established to be mobile comprise two types of loading identified in the figures by arrows f1 and f2. The track element control of a track element embodied as a bumper manages memory locations of two types of loading, wherein, however, the memory locations of the one type of loading are permanently assigned a blocking entry identified with
In the protection method according to the invention for the rail network, which is divided by the track elements S1, S2, . . . , Sp into the track sections G1, G2, . . . , Gq and on which the vehicles Z1, Z2, . . . , Zr can travel in dependence on data from components of a track atlas, therefore, the vehicles Z1, Z2, . . . , Zr request, from selected track elements, the steps B, R, M for assignment as a route element.
In the protection system according to the invention for a rail network, which is divided by track elements S1, S2, . . . , Sp into a plurality of track sections G1, G2, . . . , Gq and on which vehicles Z1, Z2, . . . , Zr can travel in dependence on data from components of a track atlas, therefore, the vehicles Z1, Z2, . . . , Zr are suitably embodied to request, from selected track elements, steps B, R, M for assignment as a route element. Moreover, each Si, where i=1 to p, of the selected track elements is suitably embodied automatically to assign itself as a route element, under predefined conditions, in each case for each vehicle Zm where, m=1 to r, which requests the steps for assignment as a route element from it and to output an assignment confirmation QMm,I, where m=1 to r and i=1 to p, to the respective vehicle.
Herein, each Si, where i=1 to p, of the selected track elements in each case automatically assigns itself as a route element, under predefined conditions, for each vehicle Zm, where m=1 to r, which requests the steps for assignment as a route element from it in that, in response to a first request ABZmSi, where m=1 to r and i=1 to p, of the respective vehicle Zm, where m=1 to r, in a type of loading F1; F2; F3; F4; f1; f2 requested by the respective vehicle, it makes its authorization B as a route element for the respective vehicle Zm, where m=1 to r, in response to a second request ARZmSi, where m=1 to r and i=1 to p, of the respective vehicle Zm, where m=1 to r, makes its registration R as a route element for the respective vehicle, and in response to a third request AMZmSi, where m=1 to r and i=1 to p, of the respective vehicle Zm, where m=1 to r, makes its marking M as a route element for the respective vehicle.
Therefore, the vehicle control OBUm of the respective vehicle Zm, where m=1 to r, determines, to request the steps for assignment from the respective track element Si, where i=1 to p, the requirements ABm,i, ARm,i, AMm,i, where m=1 to r and i=1 to p, and outputs the requirements to the respective track element Si, where i=1 to p, by means of communication means KMZm assigned to the vehicle control OBUm.
Therefore, a vehicle control OBUm of the respective vehicle Zm, where m=1 to r, is suitably embodied, to request the steps for assignment from the respective track element Si, where i=1 to p, to determine requirements ARm,i, ARm,i, AMm,i, where m=1 to r and i=1 to p, and to output the requirements to the respective track element Si, where i=1 to p, by means of communication means KMZm assigned to the vehicle control OBUm.
The track element control TSCi of the respective track element Si, where i=1 to p, receives the requirements ABM,i, ARM,i, AMm,i, where m=1 to r and i=1 to p, of the respective vehicle Zm, where m=1 to p, relating to the respective track element by means of communication means KMSi assigned to the track element control TSCi.
Therefore, the track element control TSCi of the respective track element Si, where i=1 to p, is suitably embodied to receive the requirements ABm,i, ARm,i, AMm,i, where m=1 to r and i=1 to p, of the respective vehicle Zm, where m=1 to r, relating to the respective track element by means of communication means KMSi assigned to the track element control TSCi.
The track element control TSCi of the respective track element Si, where i=1 to p, uses the received requirements to determine the assignment of the respective track element Si, where i=1 to p, as a route element for the respective vehicle Zm, where m=1 to r, and outputs the respective assignment confirmation QMm,i, where m=1 to r and i=1 to p, to the respective vehicle Zm, where m=1 to p, by means of the communication means KMSi assigned to the track element control TSCi.
Therefore, the track element control TSCi of the respective track element Si, where i=1 to p, is suitably embodied to use the received requirements to determine the assignment of the respective track element Si, where i=1 to p, as a route element for the respective vehicle Zm, where m=1 to r, and to output the respective assignment confirmation QMm,i, where m=1 to r and i=1 to p, to the respective vehicle (Zm, where m=1 to r) by means of the communication means KMSi assigned to the track element control TSCi.

On a modification of the rail network 1, the data records for the track elements affected by the modification are modified locally in the track elements. Therefore, the track elements are embodied such that, on a modification of the rail network, the data records for the track elements affected by the modification can be modified locally in the track elements.
In the case of a first-time authorization B or in the case of a first-time registration R of a respective track element for a respective vehicle, the entire data record of the track element is transmitted to the vehicle and deposited there. Therefore, the track elements and the vehicles are embodied such that, in the case of a first-time authorization B or in the case of a first-time registration R of a respective track element for a respective vehicle, the entire data record of the track element is transmitted to the vehicle and deposited there.
In the case of a repeat authorization B or in the case of a repeat registration R of a respective track element for a respective vehicle, at least some items of the data from the data record, which was deposited in the track element, are transmitted to the vehicle if the degree of up-to-dateness of a data record deposited in the vehicle and assigned to the track element deviates from the degree of up-to-dateness of the data record deposited in the track element. Therefore, the track elements and the vehicles are embodied such that, in the case of a repeat authorization B or in the case of a repeat registration R of a respective track element for a respective vehicle from the data record, which was deposited in the track element, at least some items of the data are transmitted to the vehicle and deposited there if the degree of up-to-dateness of a data record deposited in the vehicle and assigned to the track element deviates from the degree of up-to-dateness of the data record deposited in the track element.
In the protection system according to the invention, the vehicles Z1, Z2, . . . Zr deposit in the track elements manually input and/or manually released dynamic driving-operation data Dd1, Dd2, . . . , Ddp as a dynamic component Kdyn of the track atlas SA in parts Dd(Kdyn)1, Dd(Kdyn)2, . . . , Dd(Kdyn)p related to the track elements.
Therefore, in the protection system according to the invention, the vehicles Z1, Z2, . . . Zr are suitably embodied to deposit in the track elements manually input and/or manually released dynamic driving-operation data Dd1, Dd2, . . . , Ddp as a dynamic component Kdyn of the track atlas in parts Dd(Kdyn)1, Dd(Kdyn)2, . . . , Dd(Kdyn)p related to the track elements.

In the protection system according to the invention, each Si, where i=1 to p, of the selected track elements in each case specifies for each vehicle Zm, where m=1 to r, which requests at least one of the steps B, R, M for assignment as a route element from it, at least one signal HS; ZS.
Therefore, in the protection system according to the invention, each Si, where i=1 to p, of the selected track elements is suitably embodied in each case to specify for each vehicle Zm, where m=1 to r, which requests at least one of the steps B, R, M for assignment as a route element from it, at least one signal HS; ZS.
Herein, the respective track element Si, where i=1 to p, specifies for the respective vehicle Zm, where m=1 to r, the type, the position and the status of the at least one signal HS; ZS.
Therefore, the respective track element Si, where i=1 to p, is suitably embodied to specify for the respective vehicle Zm, where m=1 to r, the type, the position and the status of the at least one signal HS; ZS.
At least one of the signals is to be or is specified as a virtual main signal HS at a braking target point HP, which is a danger point.
At least one of the signals is to be or is specified as a virtual target signal ZS at a braking target point ZP, which is not a danger point.
In the method according to the invention, different types of train headway points ZFT.I, ZFT.II are specified. In addition, the vehicles provide different braking curves BKmA.I, BKmA.II of the same type of braking curve A. Herein, each of the different braking curves of the same type of braking curve A of the respective vehicle Zm, where m=1 to r, is in each case assigned to one of the different types of train headway points.
At least one braking target point HP, which is a danger point, forms a train headway point of a first type of train headway point ZFT.I, which is assigned to first braking curve BKmA.I of the respective vehicle. In the figures, such braking target points HP are, for example, the braking target points: HP1(−), HP1(+), HP1(Sp), HP2(Sp), HP2(+), HP3 (−), HP3 (Sp), HP4(Sp), HP4(+), HP4(−), HS6(Sp), HP6(+), HP7(−), HP7(Sp) and HP9, wherein this list is not complete.
A track element embodied as a switching device specifies at least one braking target point HP, which is a danger point.
A track element embodied as a bumper PB also specifies at least one braking target point HP, which is a danger point.
In addition, in a track section Gx with x=1 to q, a vehicle end ZE of a stationary vehicle Zm, where m=1 r, specifies for a following vehicle Zn, where n=1 to r and n≠m, at least one braking target point HP, which is a danger point.
At least one braking target point ZP, which is not a danger point, forms a train headway point of a second type of train headway point ZFT.II, to which a second braking curve BKmA.II of the respective vehicle Zm, where m=1 to r, is assigned. In the figures, such braking target points ZP are, for example, the braking target points: ZP2(−), ZP3(+), ZP6(−), ZP6(SP), ZP7(+), ZP7(Sp), ZS8(li) and ZS8(re), wherein this list is not complete.
A track element embodied as a spring-loaded switch WR specifies at least one further braking target point ZP, which is not a danger point.
In addition, in a track section Gx with x=1 to q, a vehicle end ZE of a moving vehicle Zm, where m=1 r, specifies for a following vehicle Zn, where n=1 to r and n≠m, at least one further braking target point ZP, which is not a danger point.
Furthermore, a track element embodied as a fictitious double entry/exit element FDME specifies at least one braking target point ZP, which is not a danger point.
According to the above-listed conditions (rules) I. to X. or i. to vi., the track elements S1 shown in

For the vehicle Z1, in addition to its authorization B in the type of loading F4, the track element S1 has also made its registration R. Therefore the storage entry, which the track element S1 has made for the vehicle Z1, is designated Z1BR in the table T1. The adjacent cell on the left is—in accordance with the rules—again provided with a blocking entry indicated by “/”.
Therefore, the vehicle Z2 is allowed to pass the track element S1 before the vehicle Z1. To this end, together with the definition of the marking, the track element S1 has initiated the changeover of the switch W1 by the operating element STW1 into its plus position as long as this was not already in the plus position. As soon as the vehicle, after crossing the switch W1, has passed a release point, not shown here for reasons of clarity, relating to the track element 1, the vehicle outputs a corresponding confirmation of passage to the track element S1, which then deletes the storage entry Z2BRM and the blocking entry “/” shown adjacent on the left—i.e. withdraws or cancels its authorization, registration and marking for the vehicle Z2 (see
Correspondingly, the track element S2 has made entries Z3BRM in column “F3” for the vehicle Z3, Z4BR in column “F2” for the vehicle Z4, Z2BR in column “F3” for the vehicle Z2 and Z1B in column “F3” for the vehicle Z1 in the memory locations of the track element control TSC2 (in the cells in Table T2) and also the blocking entries “/” resulting therefrom. Therefore, at the time point shown in

However, initially, the vehicle Z2 is not permitted to enter the rail track section G5 as long as the track element S3 has still not made a registration R for the vehicle Z2. Accordingly, the vehicle Z1 is also not initially permitted to enter the rail track section G3.
The vehicle Z2 outputs its second request for registration of the track element S3 as a route element to the track element S3. In response to this second request, the track element S3 informs the vehicle Z2 that it has already made its registration for the vehicle Z3, notifies it of the communication address of the vehicle Z3 and makes its registration for the vehicle Z2. The vehicle Z2 then makes contact with the vehicle Z3. On the basis of the present position in each case of the vehicle end of the vehicle Z3, the vehicle Z2 is in each case specified a present braking target point ZP(Z3) or HP(Z3) at which the vehicle Z2 then moves behind the vehicle Z3. The present braking target point ZP(Z3) is not a danger point and hence therefore a train headway point of the second type of train headway point ZFT.II as long as the vehicle Z3 is travelling in the direction of the track element S3—i.e. continues to move forward. As a result, the vehicle Z2 then switches on its steep braking curve BK2A.II in order to follow the vehicle Z3 quickly even if herein it would slip slightly over the braking target point ZP(Z3). However, as soon as the vehicle Z3 has come to a halt at the braking target point ZP3(+), the present braking target point is a danger point and hence also a train headway point of the second type of train headway point ZFT.II. As a result, the vehicle Z2 then switches from its steep braking curve BK1A.II to its flat braking curve BK2A.I since it is not permitted to slip beyond the braking target point HP(Z3).
In the same way, the vehicle outputs Z1 its second request for registration of the track element S2 as a route element to the track element S2. In response to this second request, the track element S2 informs the vehicle Z1 that it has already made its registration for the vehicle Z2, notifies it of the communication address of the vehicle Z2 and makes its registration for the vehicle Z1. The vehicle Z1 then makes contact with the vehicle Z2. On the basis of the present position in each case of the vehicle end of the vehicle Z2, the vehicle Z1 is in each case specified a present braking target point at which the vehicle Z1 then presently moves behind the vehicle Z2. Here, once again, the present braking target point ZP(Z2) is not a danger point and hence therefore a train headway point of the second type of train headway point ZFT.II as long as the vehicle Z2 is travelling in the direction of the track element S2—i.e. continues to move forward. As a result, the vehicle Z1 then switches on its steep braking curve BK1A.II in order to follow the vehicle Z2 quickly even if herein it would slip slightly over the braking target point ZP(Z2). However, if the vehicle Z2 were, for example, to have come to a halt before the switch W2 at the braking target point HP2(Sp), the present braking target point for the vehicle Z1 would be a danger point and hence also a train headway point of the second type of train headway point ZFT.II. As a result, the vehicle Z1 would then switch from its steep braking curve BK1A.II to its flat braking curve BK1A.I since it is not permitted to slip beyond the braking target point HP2(SP).
At the time point shown in
The vehicle Z1 outputs its second request for registration of the track element S3 as a route element to the track element S3. In response to this second request, the track element S3 informs the vehicle Z1 that it has already made its registration for the vehicle Z2, notifies it of the communication address of the vehicle Z2 and makes its registration for the vehicle Z1. The vehicle Z1 then makes contact with the vehicle Z2. On the basis of the present position in each case of the vehicle end of the vehicle Z2, the vehicle Z1 is in each case specified a present braking target point ZP(Z2) or HP(Z2) up to which the vehicle Z1 then moves behind the vehicle Z2. The present braking target point ZP(Z2) is not a danger point and hence also a train headway point of the second type of train headway point ZFT.II as long as the vehicle Z2 is travelling in the direction of the track element S3—i.e. continues to move forward. As a result, the vehicle Z1 switches on its steep braking curve BK1A.II in order to follow the vehicle Z2 quickly even if herein it would slip slightly over the braking target point ZP(Z2). However, as soon as the vehicle Z2 has come to a halt at the braking target point HP(Z3) behind the vehicle Z3, the present braking target point is a danger point for the vehicle Z1 and hence also a train headway point of the second type of train headway point ZFT.II. As a result, the vehicle Z1 then switches from its steep braking curve BK1A.II to its flat braking curve BK1A.I since it is not permitted to slip beyond the braking target point HP(Z2).
