Definitions

  • the invention relates to a method for transferring telegrams from a route control center of a train control system to a control unit of a vehicle according to claim 1.
  • the invention also relates to a route control center of a train control system according to claim 10.
  • the invention relates to a computer program product according to claim 12 and a provision device for this computer program product according to claim 13.
  • the transfer of telegrams is used to transmit information from a route control center to the trains traveling on the relevant route section.
  • the route section in question is the one that is controlled by the relevant route control center.
  • ETCS European Train Control System
  • RBC Radio Block Center
  • the telegrams are transmitted to an on board unit (OBU), which serves as a control device in the vehicle.
  • OBU on board unit
  • different route sections can be operated with different expansion levels of the ETCS system. These are characterized by different levels. There are levels 0 to level 3 as well as level NTC (national standards).
  • the vehicle (train) has a buffer memory, also called a transition buffer in the ETCS standard.
  • the buffer memory is used to take current telegrams with you to the next section of the route, so to speak.
  • the telegrams are stored in the buffer memory and are therefore still available in the next section of the route.
  • the use of the transition buffer is defined in subset-026-4 under 4.8.5 ff. It is then provided that if three telegrams are already stored in the transition buffer, each new telegram should be saved and the oldest telegram should be deleted.
  • a Movement Authority is sent. Further general telegrams (e.g. general messages) are then sent. The Movement Authority is then deleted by the third of these telegrams. This results in emergency braking if, for example, the vehicle switches to ETCS Level 2, because a Movement Authority is required in this level and is not present in the present example.
  • document CN 102 104 547 A describes a method for transmitting data messages in a train control system, comprising the steps of: obtaining the priority of a data message to be transmitted from a radio center; marking the priority into a quality of service mark of the data message; and transmitting the priority marked data message through a transmission network.
  • document EP 2 746 130 A1 relates to a method and apparatus for sending a temporary speed restriction command in a distributed manner System.
  • the system receives a temporary speed limit command; the system automatically divides it according to the starting point of the speed restriction zone, the end point of the speed restriction zone and the responsibility of each train control unit on the railway line, and then sends a corresponding temporary speed restriction command to the related train control units, and they send the speed restriction information to an on-board device of a vehicle via an active transponder .
  • document DE 22 15 724 A1 relates to a device for train protection with linear information transmission between the trains and a route center of a route area divided into track sections.
  • a data processing system determines the driving command data for the trains against the direction of travel from the route data stored therein and from the train data stored in a train memory. Querying triggers the cyclic transmission of query signals with these driving command data to the trains and determines the occupied track sections from the trains' response signals.
  • the object of the invention is to provide a method for transferring telegrams from a route center to a vehicle, with which it is possible to give priority to more important telegrams over less important telegrams when the operating conditions change, for example a level transition or an RBC-RBC transition (also called RBC-RBC handover) according to the ETCS standard. It is also an object of the invention to provide a route control center which, in the event of a change in operating conditions, as stated above, ensures the transfer of primarily more important telegrams. Finally, the object of the invention is to provide a computer program product and a provision device for this computer program product with which the aforementioned method can be carried out.
  • the term "is discarded" means for the telegram to be transferred that it is not written to a storage space and for a transferred telegram that it is deleted from the storage space and the telegram to be transferred is written to the storage space.
  • the method according to the invention ensures that more important telegrams are retained in any case, even if they are already older and have therefore been stored in the buffer memory for a long time. Younger telegrams are therefore only written into the mirror buffer memory (to be precise, into a memory location in the mirror buffer memory) if either there is still an empty memory space available or less important telegrams are stored in the available memory spaces.
  • storage space is made available for the method in the route center, with which the mirror storage buffer can be implemented.
  • This Storage space must have a sufficiently large capacity so that the route control center can, so to speak, look after several trains at the same time in the relevant section of the route.
  • the mirror buffer memory is used whenever a vehicle transition takes place.
  • a transition can consist, for example, of an RBC-RBC transition or a level transition according to the ETCS standard.
  • the difference between the buffer memory in the on-board control unit and the mirror buffer memory in the control center is that the buffer memory must be operated according to the ETCS standard if the automatic train control system is ETCS.
  • the mirror buffer memory which is operated in the route center, is not provided for in the ETCS standard, so that its operation can be subject to other rules without violating the ETCS standard. Therefore, the control center can send the telegrams stored in the mirror buffer memory if necessary and ensure that they are written into the buffer memory of the vehicle control unit and are available there, taking their importance into account. Deleting important telegrams as required by the ETCS standard can therefore be advantageously prevented by resending them without violating the ETCS standard.
  • the telegrams from the mirror buffer memory are sent in the order of their importance the control unit is sent, i.e. the least important first and the most important last.
  • the telegrams are sent in the order of their importance using the method according to the invention, since the age of the telegrams then corresponds to their importance, ie the most recent telegram is also the most important (i.e. the one with the highest priority).
  • sorting the telegrams according to their importance is not absolutely necessary if the method according to the invention is used again at the next transition; in other words, a further mirror buffer memory ensures that all important telegrams are retained again.
  • the terms “create”, “compute”, “compute”, “determine”, “generate”, “configure”, “modify” and the like preferably refer to actions and/or Processes and/or processing steps that change and/or create data and/or convert data into other data.
  • the data is available in particular as physical quantities, for example as electrical impulses or as measured values.
  • the required instructions/program commands are summarized in a computer program as software.
  • the terms “receive,” “send,” “read in,” “read out,” “transmit,” “write,” “transfer” and the like refer to the interaction of individual hardware components and/or software components via interfaces.
  • the interfaces can be hardware-related, for example wired or as a radio connection, and/or software-related, for example as an interaction between individual program modules or program parts of one or more computer programs.
  • “computer-aided” or “computer-implemented” can be understood to mean, for example, an implementation of the method in which a computer or several computers execute or execute at least one method step of the method.
  • the term "computer” is to be interpreted broadly, covering all electronic devices with data processing capabilities. Computers can therefore be, for example, personal computers, servers, handheld computer systems, pocket PC devices, mobile radio devices and other communication devices that process computer-aided data, processors and other electronic devices for data processing, which can preferably also be combined to form a network.
  • a “memory unit” can be understood to mean, for example, a computer-readable memory in the form of a random access memory (RAM) or data memory (hard drive or data carrier).
  • the procedure of this embodiment of the invention corresponds to the ETCS standard. It is then provided that the telegram to be deleted is selected in the vehicle control unit only with a view to the age of the telegram. This means that The telegram that has been in the buffer memory the longest is always deleted. However, this can be a telegram, which is required at the latest when the vehicle moves to another section of the route (level transition or RBC-RBC handover).
  • Such an emergency braking can be prevented, for example, if the Movement Authority is given such a high priority that it cannot be displaced by general messages.
  • ETCS is used as the train control system.
  • the specific number is three. In other words, this means that the buffer memory provides three storage locations for telegrams, as provided for in the ETCS standard.
  • all telegrams stored in the memory locations of the mirror buffer memory are only transferred to the control unit of the vehicle if at least one of the memory locations of the mirror buffer memory has been rewritten after the evaluation step.
  • the telegrams are assigned to a number of priority levels during the evaluation.
  • the stated task is alternatively achieved according to the invention with the subject matter of the claim specified at the beginning (route center) in that the route center has a Has mirror buffer memory, wherein the mirror buffer memory has storage spaces for telegrams to be transferred or transferred.
  • the route control center is thus equipped with the hardware and software requirements in order to carry out the above-mentioned method.
  • the memory locations must be available in a certain number (preferably three) so that a mirror buffer memory can be operated in the route center.
  • the route control center can hold the individually assigned memory locations for several trains at the same time.
  • the mirror buffer storage powder has enough storage space so that several sets of storage locations can be kept free in a certain number. Each set of memory locations is then assigned to a vehicle during operation.
  • a provision device for storing and/or providing the computer program product.
  • the provision device is, for example, a data storage medium that stores and/or provides the computer program product.
  • the provision device is, for example, a network service, a computer system, a server system, in particular a distributed computer system, a cloud-based computer system and/or virtual computer system, which stores and/or provides the computer program product, preferably in the form of a data stream.
  • the provision is made, for example, as a download in the form of a program data block and/or command data block, preferably as a file, in particular as a download file, or as a data stream, in particular as a download data stream, of the complete computer program product.
  • This provision can, for example, also take place as a partial download, which consists of several parts and is downloaded in particular via a peer-to-peer network or provided as a data stream.
  • Such a computer program product is, for example, read into a system using the provision device in the form of the data carrier and executes the program commands, so that the method according to the invention is carried out on a computer or the creation device is configured in such a way that it produces the workpiece according to the invention.
  • the route control centers RBC1, RBC2 control a route ST on which vehicles FZ1, FZ2 travel in the form of two traffic trains. These pass through different route sections STA1, STA2, STA3.
  • the first route section STA1 is controlled by the route control center RBC1, while the second route section STA2 is controlled by the second route control center RBC2.
  • the route control centers RBC1, RBC2 implement the ETCS standard for train communication at Level 3 L3 (ETCS stands for European Train Control System).
  • ETCS European Train Control System
  • Computers CP1, CP2 are provided in the route control centers RBC1, RBC2, which take on the tasks of automatic train control.
  • control units SG1, SG2 are available, which are equipped to carry out automatic train control operation according to the ETCS standard.
  • the first route control center RBC1, the second route control center RBC2, the first vehicle FZ1, the second vehicle FZ2 and possibly other vehicles (not shown) communicate with each other via the interfaces S1...S4, as explained in more detail below becomes.
  • the control devices SG1, SG2 in the vehicles FZ1, FZ2 each have a buffer memory PS1, PS2, in which three memory locations SP1, SP2, SP3 for telegrams T1...T4 (see FIG 2 ) are provided.
  • Computers CP1, CP2 are used in the route control centers RBC1, RBC2, with the help of which the automatic train control system is operated.
  • the computers CP1, CP2 also provide storage space, which is used as the first mirror buffer memory SPS1 in the computer CP1 and as the second mirror buffer memory SPS2 in the computer CP2.
  • Storage locations SP1...SP6 are also provided in the mirror buffer memories SPS1, SPS2, into which telegrams T1...T4 (cf. FIG 2 ) can be written. Examples are in FIG 1
  • Six memory locations SP1...SP6 are represented in each of the mirror buffer memories SPS1, SPS2, which would be sufficient, for example, according to the ETCS standard for two vehicles FZ1, FZ2 in the respective route section STA1...STA3.
  • the computers CP1, CP2 also offer sufficient storage capacity for additional storage locations (not shown), so that more than two vehicles can be controlled in the relevant section of the route.
  • the computers can also have several mirror buffer memories, one mirror buffer memory for each train.
  • the first vehicle FZ1 which is traveling in the direction of RI1 on the ST route, is in FIG 1 an RBC-RBC handover is shown.
  • Train control is transferred from the route control center RBC1 in route section STA1 to the route control center RBC2 in route section STA2.
  • the first vehicle FZ1 communicates with the first route center RBC1 via the third interface S3.
  • telegrams important for train operation are sent from the first route control center RBC1 to the first vehicle FZ1 and stored in the memory locations SP1...SP3 of the first buffer memory PS1.
  • the same telegrams are also stored in the memory locations SP1...SP3 of the first mirror buffer memory SPS1 in the computer CP1.
  • all three telegrams stored in the memory locations SP1...SP3 of the first mirror buffer memory SPS1 are sent to the first vehicle FZ1 via the third interface S3 whenever a new telegram has been written into the first mirror buffer memory SPS1.
  • all three older telegrams are deleted from the memory locations SP1...SP3 in the first buffer memory PS1 of the first vehicle FZ1, which ensures that the ones in the first Mirror buffer memory SPS1 stored high priority telegrams are also stored in the first buffer memory PS1.
  • FIG 1 Another example according to FIG 1 is the transition of the second vehicle FZ2, which is traveling in a direction RI2, changing from the route section STA3 with ETCS level 0 to the second route section STA2 with ETCS level 3. This is therefore a level transition.
  • the smooth operation of the second vehicle FZ2 is only guaranteed if important, ie high-priority telegrams are available in the second route section STA2. These are therefore transferred in the manner described for the first vehicle FZ1 via the fourth interface S4 from the second mirror buffer memory SPS2 in the second route center RBC2 into the second buffer memory PS2 of the second vehicle FZ2. This also ensures that this always happens when telegrams are overwritten in one of the memory locations SP1...SP3 of the second mirror buffer memory SPS2.
  • the necessary telegrams are therefore available in the second vehicle FZ2 when traveling through the second route section STA2, which is operated at ETCS level 3. It should be noted that the second route center RBC2 remains responsible in the second route section STA2. Although this is in FIG 1 However, as explained above, a situation would also be conceivable in which an RBC-RBC handover and a level transition coincide, ie a change from one route section to another takes place, with different route centers being responsible for both route sections and the Route sections also differ in terms of their operating mode in the level.
  • FIG 2 the process flow is shown as an example for the first route center RBC1. However, it should be noted that the process works analogously in the second route center RBC2.
  • the alternative A1 is that the method has just been started, in which case the first buffer memory PS1 is still empty.
  • step 2 the decision is made in step 2 as to whether all memory locations SP1...SP3 (cf. FIG 1 ) are occupied in the first mirror buffer memory SPS1. If this is not the case, in step 3 the telegram T1 is transferred to the first mirror buffer memory SPS1 and also to the first buffer memory PS1 of the first vehicle FZ1 (cf. FIG 1 ) transmitted. To the left of step 3 it is shown which memory constellations can result in the memory locations SP1...SP3 both in the first buffer memory PS1 and in the first mirror buffer memory SPS1. Accordingly, one, two or three of the memory locations SP1...SP3 are occupied. This applies in the same way to the next two telegrams T2 and T3. For a fourth telegram T4 and further telephones (T5, T6, etc., not shown), alternative A2 of the method, described in more detail below, is run through.
  • step 4 the already stored telegrams and the telegram currently to be transmitted are prioritized. These are the telegrams T1...T4. After the prioritization step, it can be decided which three telegrams of the telegrams T1...T4 have the highest priority (in the following it is assumed, for example, that the telegram currently to be transmitted is T1 - but nothing changes qualitatively in the process if a another telegram is currently to be transmitted).
  • step 5 a query is made as to whether the telegram T1 currently to be transmitted has been deleted. If this is the case, no further action is necessary. However, if this is not the case, step 6 is carried out, with the three relevant telegrams T1...T4 being written to the memory locations SP1...SP3 of the first mirror buffer memory SPS1 and the buffer memory PS1. This means that the most relevant (i.e. highest prioritized) telegrams for further travel are stored in the buffer memory PS1 of the first vehicle FZ1 and the same telegrams are stored in the first mirror buffer memory SPS1 in order to be able to carry out prioritization again in a subsequent step 4.
  • Step 5 is not absolutely necessary. Even if the telegram T1 currently to be transmitted has been deleted, the telegrams T2, T3 and T4 can be transmitted without a query, since these are the most relevant telegrams, which, however, were also stored in the first mirror buffer memory SPS1 and the first buffer memory before this storage step PS1 templates.
  • a step 7 it is checked whether the RBC-RBC transition or a level transition to level 2 or to level 3 is completed (DONE?). If this is not the case, the procedure is repeated for the next telegram transmitted, with the route center RBC1 generating the next required telegram T1. As long as memory locations SP1...SP3 are still free, the next process cycle is processed according to alternative A1. If all memory locations SP1...SP3 are already occupied, this is indicated in step 1 by alternative A2. In this case, only telegram T4 is added as an example, whereby the query according to step 2 leads to step 4, since all memory locations SP1...SP3 are already occupied. This naturally also applies to all other telegrams T5, T6..., even if this is not shown in Figure two.
