Abstract
Description
- The present invention concerns a system and a method for traffic management of railway networks.
- As known, railways networks are very complex systems formed by many components and devices such as, for example, interconnected track lines, points, railway level crossings, stations, train convoys, signaling systems, decentralized and centralized control centers, et cetera.
- Clearly, all these components and devices must be properly coordinated, continuously monitored, and timely operated, in order to ensure the correct and efficient functioning of the whole railway network, while satisfying the highest standards of safety, which is a very critical aspect in the railroad industry.
- To this end, in particular thanks to the development of computer and IC technologies, various solutions have been recently devised for advanced and safer management of traffic in railway networks.
- These solutions are essentially based on the generation of virtual data and/or availability of real data, such as the railway architecture, the operating state of traffic signals, the positions of trains or of points, and the like.
- Data, either collected from the field and/or built virtually, are elaborated in control centers where management of railway traffic is conducted on the basis thereof.
- For example, a typical configuration of a traffic management system for railways foresees the use of one or more traffic servers monitoring the state of equipment and the positions of trains.
- When an abnormality is detected, based for instance on the status signal received from a signaling device, a warning information is output towards a terminal display where an operator is required to launch an appropriate action which is elaborated and put in place for execution by one of the servers.
- An example of a solution aimed at improving traffic management systems for railway applications is disclosed in
US 2015/0213080 A1 in which various initial data about tracks layout are collected and saved in a database where the track layout is modeled. Then, subsequent virtual data are elaborated and saved in a verification database and a processing device compares the subsequent data with the initial data in order to improve track data to be sent to central control units and/or to onboard controllers of trains. - Another solution related to traffic management systems for railway networks is described in
EP 2 735 492 A2 , which deals specifically with traffic timetables where a current operating timetable is replaced by a new timetable generated on the basis of operative information received from the field, e.g. train delays, traffic disruption or the like. - Although prior art solutions, like the ones previously mentioned, have afforded and tried over the years to improve various aspects of traffic management in railway systems, there is still room and desire for further improvements.
- Therefore, it is a main aim of the present invention to fulfill at least partially such room and desire, and hence to provide a system and method for traffic management of a railway network, having improved performances in particular as regard to safety related aspects and operations, and especially when dealing with generation, management and execution of pluralities of operations to be executed.
- Within the scope of this aim, an object of the present invention is to provide a system and method for traffic management of a railway network having, with respect to prior art solutions, an increased level of integration and coordination among various components and operators involved in the traffic management of railway networks.
- An additional object of the present invention is to provide a system and method for traffic management of a railway network which can be applied and scalable to different and varying architectures and sizes of railway networks.
- Yet a further object of the present invention is to provide a system and method for traffic management of a railway network which is highly reliable, easy to realize and at competitive costs.
- This aim, these objects and others which will become apparent hereinafter are achieved by a traffic management system for a railway network, characterized in that it comprises:

- This aim, these objects and others which will become apparent hereinafter, are achieved also by a method for traffic management of a railway network, characterized in that it comprises the steps of:

figure 1 , thesystem 100 comprises a storage device, 5, e.g. a storage database or server, and at least onehuman machine interface 10 for interfacing with one or more operators who are devoted to supervise the correct functioning of thewhole railway network 200 or any part thereof under their responsibility, for example safe operators and assistants. - For instance, the
human machine interface 10 can comprise one or more workstations or consoles installed in a centralized control room. - The
system 100 comprises asystem 20 for monitoring and controlling therailway network 200, wherein the monitoring and controllingsystem 20 is configured to generate one or more batches, i.e. one or more groups, of command instructions suitable to be issued for execution to one or more of thefield devices 201 by the one or more operators of thesystem 100. - For example, the monitoring and controlling
system 20 can comprise a programmable software and related circuitry tool for monitoring the state of therailway network 200 in terms of infrastructure and traffic, for assuming if necessary automatic control and supervision based on real-time events and, by collecting relevant operational data in real time, for assessing occurring situations and generating corresponding command instructions for operators, for instance for resolving incoming operative conflicts. - The
system 100 comprises at least oneelaboration device 30 which is for example in operative communication with the at least onecommunication interface 1 and with the at least onehuman machine interface 10. - In particular, the
elaboration device 30 is configured, upon generation by the monitoring and controllingsystem 20 of at least one batch of command instructions, to carry out a safety procedure for evaluating a response of therailway network 200 in relation to the generated at least one batch of command instructions, and to output to the at least onehuman machine interface 10, for the attention and in case action of one or more operators, information indicative of the results of the safety procedure carried out, as for example illustrated infigure 3 . - In one embodiment, the
elaboration device 30 is configured to carry out, as a part of the safety procedure, a pre-execution validation procedure for verifying if the command instructions included in the generated at least one batch fulfill desired operative conditions of therailway network 200, and to output to the at least onehuman machine interface 10, for the one or more operators, information indicative of the results of the pre-execution validation procedure carried out. - In this way, by carrying out a validation procedure before a generated batch of command instructions is issued for execution to one or more of the
field devices 201, the traffic system operators have the possibility to verify in advance if the batches of command instructions to be executed are compliant with the actual status of the railway network or, if applied, could violate any constraint thereof. - Accordingly, the level of safety in managing interventions on the
railway network 200, thanks to this preventive check, is substantially increased. - Once verified that the command instructions of a generated batch subjected to the validation procedure fulfill the desired operative conditions of the
railway network 200, an operator can output to thecommunication interface 10, via theelaboration device 30, the pre-validated batch of command instructions for immediate execution. - In turn, the
communication interface 1 dispatches the batch to one or more of thefield devices 201 for the material execution. - According to an embodiment, the
elaboration device 30 is also configured to allow an operator to send, via theelaboration device 30, the pre-validated batch to thestorage device 5 where it is saved for later execution. - In this way, it is possible to improve the efficient management of the
railway network 200, according to a more flexible and desired schedule since the batches of command instructions are prepared and planned in advance and, once validated and stored, they can be retrieved and are ready for immediate application at request. - According to an embodiment, the
elaboration device 30 is configured to carry out, as a part of the safety procedure, a post-execution confirmation procedure for verifying if an expected operative status of therailway network 200 based on the foreseen execution of a generated batch of command instructions corresponds with the actual status of therailway network 200 based upon signals received from one ormore field devices 201, via thecommunication interface 1, after execution of the generated batch of commands instructions, and then to output to thehuman machine interface 10, for the attention and in case action of one or more operators, information indicative of the results of the post-execution confirmation procedure carried-out. - For example, the expected status is based on network configuration data stored in a database, e.g. in the
storage device 5, where a list of expected statutes are saved and can be retrieved, case by case, using the command instructions under execution as an input for, while information of the results of the confirmation procedure can be presented to the operators by means of text messages and/or graphic symbols, or any combination thereof. - Hence, operators of the
system 100 have the possibility to check if the batch of command instructions has been correctly and completely executed according to the desired configuration of therailway network 200 to be achieved, eventually closing the task in the affirmative case. - In the contrary case, the execution of batch command instructions is aborted and operators have further the possibility to execute another instance of the same batch of command instructions.
- In this way, the level of safety in managing interventions on the railway network is further increased.
- According to an embodiment, the post-execution confirmation procedure is preferably carried out on a batch of command instructions which has been subjected to the pre-execution validation procedure.
- However, depending on the applications and operative circumstances, it would be possible, if necessary, to carry out the post-execution confirmation procedure on a batch of command instructions which was not subjected to the pre-execution validation procedure.
- According to an embodiment, the monitoring and controlling
system 20 is configured to generate, not only a single batch of command instructions, but also complete intervention plans scheduled for therailway network 200, wherein each of the intervention plans comprises one or more phases which are arranged according to a desired sequence of execution and each phase includes, namely is formed by, a corresponding batch of command instructions suitable to be sent to and executed by one or more of thefield devices 201. - For example, an intervention plan can be related to a global maintenance operation planned for the
railway network 200 and is composed by different phases, with a phase formed by a batch of commands. - In practice, as shown in
figure 5 , each command instruction 101-106, corresponds to a planned action to be executed, and various command instructions are grouped in a batch of concatenated command instructions forming a phase of the plan. - For instance, in the example illustrated in
figure 5 , phase A is formed by a set ofcommand instructions command instructions command instructions - In turn, the phases are concatenated with each other, according to a desired sequence of operations, forming as a whole an
intervention plan 400 which can be initially pre-stored, e.g. inside the same monitoring and controllingsystem 20, or elsewhere. - When the monitoring and controlling
system 20 requires operators to execute theintervention plan 400, similarly to what previously described about one single batch of command instructions, theelaboration device 30 is configured to retrieve the intervention plan and carry out the pre-execution validation procedure for each individual command instruction included in the one or more phases of a selected intervention plan and cumulatively for each complete phase of the selected intervention plan, and then to output to thehuman machine interface 10, for the attention and in case action of one or more operators, information indicative of the results of the pre-execution validation procedure carried out for each individual command instruction included in each phase of a selected intervention plan and cumulatively for each complete phase of the selected intervention plan. - Also in this case, once verified that the command instructions of each phase of the selected intervention plan fulfill the desired operative conditions of the
railway network 200 to be achieved, an operator can trigger direct execution of the pre-validated intervention plan for thefield devices 201. - Alternatively, the
elaboration device 30 is further configured to allow operators to save the intervention plan in thestorage device 5 for later direct execution, and/or to generate a template based on the pre-validated selected intervention plan and to save the template in thestorage device 5 where it is stored for later generation of additional intervention plans. - In particular, according to an embodiment, the
elaboration device 30 is configured to assign a unique identifier to each individually saved batch of command instructions or to each intervention plan or intervention template, for direct and correct retrieval thereof by theelaboration device 30, when related execution or use is requested to operators by the monitoring and controllingsystem 20. - In this way, it is possible to build an archive of intervention plans which can be used at request and more than once, or to have a starting template having at least some parts pre-validated and usable for completion with additional batches, so that to generate new intervention plans in a quicker way.
- Further, also in this embodiment the
elaboration device 30 is preferably configured to carry out the post-execution confirmation procedure and to output to thehuman machine interface 10, for the attention and in case action of one or more operators, information indicative of the results of the post-execution confirmation procedure carried out for each individual command instruction included in each phase of a selected intervention plan, and cumulatively for each complete phase of the selected intervention plan. - In this way, for an intervention plan under execution, it is possible to verify, step by step, if the batch of command instructions forming a phase and each overall phase itself have been completely and correctly executed.
- Thus, operators are able to verify if the expected operative status of the
railway network 200 based on the foreseen execution of a phase corresponds with the actual status of therailway network 200 based upon signals received from one ormore field devices 201, via thecommunication interface 1, after execution of the batch of commands instructions forming each phase. - In this way, it is possible to verify the correct execution on a multi-phase plan and in case to stop it if anything did not proceed as necessary.
- For example, the exemplary intervention plan illustrated in
figure 5 can be part of a global maintenance intervention plan scheduled for therailway network 200, where operators need to take possession, i.e. to isolate, a sub-area of thenetwork 200 first, to execute maintenance needed after, and then to proceed with a following sub-area, et cetera. - Accordingly, phase A of the intervention plan would include all command instructions needed to take possession of the specific subarea, phase B of the intervention plan would include all command instructions needed to perform maintenance in the isolated/specific subarea, and phase C of the intervention plan would include all command instructions needed for re-putting in operation the specific sub-area.
- The same process, with corresponding phases can be repeated sub-area after sub-area, in a way that allows incrementing and decrementing the areas under possession, with great flexibility and minimizing the impact on the railway traffic.
- Then, the
elaboration device 30 outputs to thehuman machine interface 10, for the attention and in case action of one or more operators, information indicative of the results of the confirmation procedure carried-out for each command instruction included in the batch forming a phase and for each phase as a whole. - In particular, the
elaboration device 30 is configured to output to thehuman machine interface 10, within the post execution confirmation procedure, a command for an operator to stop execution of an intervention plan, if for at least one of the command instructions included in a phase or for the overall phase of the intervention plan under execution, the actual status of therailway network 200 differs from the expected status. - In this way safety is substantially improved due to the fact that if one of the command instructions in a phase, e.g. in phase A, would fail, operators would immediately know that the selected sub-area is not in the needed safety conditions for having workers deployed there, and therefore workers can be prevented from entering in such potentially unsafe sub-area.
- System operators have then the possibility to try again completion of the phase, or in the end to abort and remove all command instructions already executed.
- Clearly, a command for an operator to stop execution is likewise applicable when carrying out a post-execution confirmation procedure on a generated single batch of command instructions previously described if, for at least one of the command instructions under execution, the actual status of the
railway network 200 differs from the expected status. - Further, also when dealing with a complete intervention plan formed by one or more concatenated phases, it is possible to carry out the post-execution confirmation procedure preferably on an intervention plan subjected to the pre-execution validation procedure.
- However, depending on the applications and operative circumstances, it would be possible, if necessary, to carry out the post-execution confirmation procedure on an intervention plan which was not subjected to the validation procedure.
- Depending on the applications, operators of the
traffic management system 100 according to the present invention, can decide, e.g. at design time, whether the safety procedure above described, and in particular the pre-execution validation procedure and/or the post-execution confirmation procedure, can be executed always, or only if certain conditions are met. - In one embodiment of the
traffic system 100 according to the present invention, theelaboration device 30 is configured to carry out an identification procedure for an operator to verify if at least one command instruction included in a generated batch of command instructions, be it an individual batch or a batch forming a phase of a multi-phase intervention plan, meets a predetermined criteria, and only in the affirmative case, to carry out the safety procedure, and in particular any of the related pre-execution validation procedure and/or post-execution confirmation procedure, for the batch subjected to the identification procedure. - In particular, according to the invention, a list of possible commands is predefined and stored, for example in the
elaboration device 30, wherein the commands are classified each according to at least a first category and a second category, with the commands of the first category having a hierarchical importance higher than those commands belonging to the second category, in particular as regard to safety related actions. - For instance, the pre-listed command instructions are classified as "vital" or "critical" for the first category, and as "standard" for the second category, with respect to a reference criteria establishing that failure of execution of a standard command instruction per se would not cause any safety related issue on the
railway network 200, while failure of execution of a vital or critical command would cause safety issues which must be prevented or mitigated as quickly as possible. - When vital or critical command instructions are included in a batch, such batch and all information and data related therewith are preferably always routed through the
elaboration device 30, either when operators will issue such command instructions for execution to thecommunication interface 1, or as regard to the status signals received by thecommunication interface 1 in response to the application of the batch of command instructions, which status signals should be properly transferred and displayed to the operators on thehuman machine interface 10. - According to an embodiment, the
elaboration device 30 is a drawing server, e.g. a graphical programmable tool comprising suitable software code and related circuitry, which is configured to generate, on one or more of thedisplays 15 associated to thehuman machine interface 10, graphical information indicative of the safety procedure carried out, and in particular of the related pre-execution validation procedure and/or post-execution confirmation procedure carried out. - For example, for the pre-execution validation procedure, the
elaboration device 30 will provide to the human machine interface, the list of the command strings and related graphic visualization associated to all controls included and the general information associated to the current batch. - In case of a post-execution confirmation procedure, if for example a batch/phase is composed by twenty individual command instructions, operators will see on one or more of the
displays 15, a total of twenty-one results displayed, namely one for each individual command, and one for the whole batch/phase. - In this way, operators can obtain at a glance, a feedback on whether the execution of multiple command instructions is proceeding correctly, as for example illustrated with the sketch of
figure 3 . - According to an embodiment, the
elaboration device 30 is configured to generate a graphical comparator comprising a first expected execution image and a second resulting execution image visualized on the one ormore displays 15, wherein if the first and second images differ from each other, theelaboration device 30 is configured to output to the human machine interface 10 a corresponding information allowing to enter a failure mode. - According to an embodiment schematically illustrated in
figure 4 , thesystem 100 comprises a plurality ofelaboration devices 30, i.e. at least twoelaboration devices 30. - In particular, if only two
elaboration devices 30 are used, they would be substantially identical to each other and would be capable to perform exactly the same tasks in a synchronized way and independently from each other, thus allowing safe redundancy for thewhole system 100. - In a particularly preferred embodiment of the
system 100 according to the invention, there is provided a plurality ofelaboration devices 30, each being capable to perform the same procedures previously described. - According to this embodiment, the
elaboration devices 30 can be divided in groups of two ormore elaboration devices 30, wherein each group is assigned to a dedicated sub-part of therailway network 200, and theelaboration devices 30 of the same group are configured to perform the same tasks in a synchronized way and independently from each other. - According to this embodiment, the at least one
human machine interface 10 is configured to selectively connect with at least two of the plurality ofelaboration devices 30 via acommunication bus 25, which is substantially a multiplexer, hosted for example by thestorage device 5. - During operations, the
elaboration devices 30 publish dynamically their respective load which is taken into account by thecommunication bus 25. - If a
human machine interface 10 queries thecommunication bus 25, thecommunication bus 25 provides the IP address of theelaboration device 30 to which the queryinghuman interface 10 should preferably connect to. - Such indication is for example based on a load balancing principle, i.e. the
communication bus 25 indicates to thehuman machine interface 10 the right and lessloaded elaboration device 30, thus allowing a faster and more efficient management of data handling among the various parts of thesystem 100. - Further, as illustrated in
figure 4 , it is possible for thesystem 100 to be scaled up as desired, namely to comprise a plurality of human machine interfaces 10 for interfacing each with one or more operators, and a plurality ofcommunication interfaces 1 for interfacing with thevarious field devices 201 of therailways network 200, wherein the plurality ofelaboration devices 30 is in operative communication with the plurality of human machine interfaces 10 and the plurality ofcommunication interfaces 10, and wherein each of the plurality of human machine interfaces 10 is configured to selectively connect with at least two of the plurality ofelaboration devices 30 by querying thecommunication bus 25. - If needed, also the number of
storage devices 5 can be increased, as well as that of the monitoring and controllingsystems 20. - In this way, the
system 100 is easily scalable torailway networks 200 of different size, complexity and architecture, thus being applicable either to a local network or expandable to a wider one, with the expansion that can be implemented at any time. - With reference to

human machine interface 10, for one or more operators, information indicative of the results of the pre-execution validation procedure carried out for, each individual command instruction included in the one or more phases of the selected intervention plan, and cumulatively for each complete phase of the selected intervention plan. - According to this embodiment, the
