Description

[Technical Field]

[0001] The present invention relates to a diagram creation device, a train control system, and a diagram creation method, and is suitable for application to a diagram creation device, a train control system, and a diagram creation method that create operation diagrams for trains running on a line. [Background technology]

[0002] In the operation of railway vehicles (trains), the more time allowed between stations, the less energy the train needs to travel between those stations, and the greater the energy-saving effect. Furthermore, the energy-saving effect of allocating travel time varies depending on the distance between stations. Taking advantage of this property, a method is known that improves energy efficiency without changing the travel time of the entire line by allocating more time to stations where the energy-saving effect is high.

[0003] For example, Patent Document 1 describes a method for recreating a train schedule when the operating conditions change by reallocating slack time based on the energy-saving effect between stations where trains will subsequently travel. [Prior art documents] [Patent documents]

[0005] However, the conventional method of allocating a larger amount of required time between stations with a high energy-saving effect results in some stations not being allotted much required time, which can lead to situations where it is difficult to recover from delays when they occur. For example, in the system disclosed in the above-mentioned Patent Document 1, if a large amount of slack time is allocated between stations before a delay occurs, there is no slack time available for allocation to the stations between which the train will run after the delay occurs, so even if the train runs at its fastest speed after the delay occurs, it may not be able to recover from the delay and it may not be possible to maintain punctuality.

[0006] The present invention has been made in consideration of the above points, and by providing leeway time between stations in consideration of the characteristics of the energy required by trains running between stations and the effect of recovering from delays, it is possible to keep trains running on schedule even when delays occur during operation. sex The present invention proposes a diagram creation device, a train control system, and a diagram creation method that are capable of creating a train schedule that is easy to maintain.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0013] The following description and drawings are examples for explaining the present invention, and have been omitted or simplified as appropriate for clarity of explanation. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. The present invention is not limited to the embodiments, and all applications consistent with the concept of the present invention are included in the technical scope of the present invention. Those skilled in the art can make various additions and modifications to the present invention within the scope of the present invention. The present invention can also be implemented in various other forms. Unless otherwise specified, each component may be plural or singular.

[0014] Furthermore, although the following description may describe processing performed by executing a program, the program is executed by at least one processor (e.g., a CPU) to perform a predetermined process using storage resources (e.g., memory) and / or interface devices (e.g., communication ports) as appropriate, and therefore the processor may be the subject of the processing. Similarly, the subject of the processing performed by executing a program may be a controller, device, system, computer, node, storage system, storage device, server, management computer, client, or host having a processor. The subject of the processing performed by executing a program (e.g., a processor) may include a hardware circuit that performs part or all of the processing. For example, the subject of the processing performed by executing a program may include a hardware circuit that performs encryption and decryption or compression and decompression. The processor operates as a functional unit that realizes a predetermined function by operating in accordance with the program. Apparatuses and systems including a processor are apparatuses and systems that include these functional units.

[0015] A program may be installed on a device such as a computer from a program source. The program source may be, for example, a program distribution server or a computer-readable storage medium. When the program source is a program distribution server, the program distribution server includes a processor (e.g., a CPU) and storage resources, and the storage resources may further store a distribution program and a program to be distributed. The processor of the program distribution server may then execute the distribution program, causing the processor of the program distribution server to distribute the program to be distributed to other computers. In the following description, two or more programs may be realized as one program, and one program may be realized as two or more programs.

[0016] In addition, in the following explanation, characteristics between stations may be expressed as "stations with long inter-station distances" or "stations with high speed limits," but if the comparison target is not explicitly stated, these characteristics may be based on the average value between each station, or on a predetermined threshold value or a threshold value determined by a predetermined calculation method.

[0017] First, each component of a train control system 1 according to an embodiment of the present invention and the function of each component will be described.

[0018] Fig. 1 is a block diagram showing an example of the configuration of a train control system 1 according to one embodiment of the present invention. As shown in Fig. 1, the train control system 1 is configured to include a diagram creation device 10, a train 20, and an operation management device 30. As will be described in detail later, in the train control system 1, the diagram creation device 10 creates a train schedule (hereinafter referred to as a schedule) by allocating the required travel time between each station based on energy characteristics and delay recovery effects, and transmits the created schedule to the train 20 and the operation management device 30.

[0019] The diagram creation device 10 includes an energy characteristics storage unit 11, a delay recovery effect storage unit 12, a slack time distribution determination unit 13, and a diagram creation unit 14.

[0020] The diagram creation device 10 is realized by, for example, a computer having a processor, memory, storage device, and input / output device. In this case, the functions of the slack time distribution determination unit 13 and the diagram creation unit 14 are realized by the processor expanding into memory a program stored in a storage device or the like and executing it. Also, the functions of the energy characteristics storage unit 11 and the delay recovery effect storage unit 12 are realized by the storage device or memory storing predetermined data.

[0021] The energy characteristic storage unit 11 has a function of storing energy characteristic information indicating the energy characteristics for each section between stations, regarding the characteristics of energy (energy characteristics) required by the train 20 running between stations.

[0022] FIG. 2 is a diagram for explaining energy characteristics. In this embodiment, the energy characteristics are expressed as the energy (e.g., power consumption) required by a train traveling between stations to which a slack time is assigned, relative to the slack time. As an example of a general energy characteristic, FIG. 2 shows the relationship between the slack time on the horizontal axis and the power consumption on the vertical axis. Note that the horizontal axis in FIG. 2 may also represent the required time, which is the sum of the slack time assigned between stations and the time required for a train to travel between the stations at the fastest speed (fastest time).

[0023] The above-mentioned power consumption amount varies depending on the slack time, and also varies depending on the distance between stations. Therefore, the diagram creation device 10 calculates in advance the power consumption amount for each of a plurality of slack times for each distance between stations based on past performance or by simulation, etc., and stores these calculation results in the energy characteristics storage unit 11 as information indicating energy characteristics (energy characteristics information). Note that the diagram creation device 10 may be configured so that energy characteristics information created outside the diagram creation device 10 is stored in the energy characteristics storage unit 11.

[0024] As shown in Figure 2, energy characteristics generally tend to show that the more slack time is added, the less energy (power consumption) is required. In other words, the longer the required time (slack time plus the fastest time) is, the less energy (power consumption) is required. As the required energy decreases, the energy saving effect increases. Furthermore, it is known that the energy saving effect of slack time (which can be replaced with required time) differs depending on the distance between stations.

[0025] Taking the above characteristics and properties into consideration, the slack time allocation determination unit 13 allocates more slack time to inter-stations that are excellent in energy conservation based on the energy characteristics of each inter-station. Specifically, "inter-stations that are excellent in energy conservation" are assumed to be inter-stations with a large downward gradient, inter-stations with few curves (with many straight routes), inter-stations with a long inter-station distance, inter-stations with a high speed limit, or inter-stations with a uniform speed limit and no complexity, etc.

[0026] The delay recovery effect storage unit 12 has a function of storing delay recovery effect information indicating the delay recovery effect (delay recovery effect) for each interval between stations when a delay occurs between the stations in the train 20. In this embodiment, an interval between stations with a high delay recovery effect is an interval between stations where a large amount of slack time is allocated to the interval between the stations, thereby increasing the probability that the delay can be recovered when a delay occurs.

[0027] The delay recovery effect information may set, for example, the following delay recovery effects: If it is anticipated that delays will occur between stations, allocating a large amount of slack time between those stations will make delay recovery easier, so the delay recovery effect between those stations is set high. If it is not anticipated that delays will occur between stations, allocating a large amount of slack time between stations on the terminal side will ensure that slack time can be used to recover from delays when they occur, so the delay recovery effect between stations on the terminal side is set high. Therefore, examples of interstations with a high delay recovery effect are anticipated to be interstations between a predetermined number of stations on the terminal side of a line, interstations between stations where delays have frequently occurred in the past, interstations with few curves, or interstations before stations where there are many transfers to other lines.

[0028] The specific value of each delay recovery effect in the delay recovery effect information is determined based on past operation data and the dispatcher's past experience. If the delay recovery effect differs depending on the time of day, such as during busy periods in the morning or during quiet periods in the afternoon, the delay recovery effect may be set to a different value for each time of day. If the delay recovery effect differs depending on the degree of delay that occurs, the delay recovery effect may be set to a different value for each degree of delay.

[0029] The value of the delay recovery effect set in the delay recovery effect information may be a fixed value calculated in advance based on past performance, etc., or may be a variable value calculated in real time. When the value is changed in real time, it may be set and changed taking into account the operation status and congestion status. Even when a fixed value is used, the value may be periodically corrected in accordance with changes in passenger usage status and the environment.

[0030] 3 is a diagram showing an example of delay recovery effect information. The delay recovery effect information 100 shown in FIG. 3 is an example of delay recovery effect information stored in the delay recovery effect storage unit 12, and has data items of item 101 and item 102.

[0031] In FIG. 3, item 101 indicates a plurality of inter-station sections included between the starting station and the terminal station in the running order of train 20. Item 102 indicates the delay recovery effect between the stations indicated by item 101. Specifically, for example, in the case of FIG. 3, a record in which the value of item 101 is "1" indicates that the delay recovery effect between the first station (between the starting station and the first station) is "10", and a record in which the value of item 101 is "2" indicates that the delay recovery effect between the second station (between the first station and the second station) is "20". Note that the value of the delay recovery effect set in item 102 is an index value, and in the above example, it means that the delay recovery effect between the second station is twice the delay recovery effect between the first station.

[0032] The slack time distribution determination unit 13 has a function of determining the slack time to be distributed between each station based on the energy characteristic information stored in the energy characteristic storage unit 11 and the delay recovery effect information stored in the delay recovery effect storage unit 12. Specifically, the slack time distribution determination unit 13 distributes the slack time between each station while allocating a large amount of slack time between stations with excellent energy-saving performance based on the energy characteristics indicated by the energy characteristic information, and distributes the slack time between each station while allocating a large amount of slack time between stations with high delay recovery effectiveness based on the delay recovery effect indicated by the delay recovery effect information, and determines the total of these slack times between each station as the slack time to be distributed between each station. For distributing the slack time based on the energy characteristics, a conventional technique such as that disclosed in Patent Document 1 can be used.

[0033] The ratio of the slack time allocated based on the delay recovery effect to the slack time allocated based on the energy characteristics can be determined according to the required specifications for punctuality and energy efficiency. For example, if punctuality is emphasized, the ratio of the slack time allocated to the delay recovery effect can be increased, and if energy efficiency is emphasized, the ratio of the slack time allocated to the energy characteristics can be increased. Furthermore, the ratio allocated to the energy characteristics can be increased within a range that does not affect delays or punctuality, which can be determined based on past performance. This is because the actual delay recovery effect is low even if excessive slack time is allocated between stations with little history of delays.

[0034] Fig. 4 is a diagram for explaining the allocation of slack time between stations. The allocation time determination table 200 shown in Fig. 4 is table data showing an example of allocation of slack time between stations by the slack time allocation determination unit 13, and has data items 201 to 205.

[0035] 4, item 201 indicates the interval between stations, and item 202 indicates the delay recovery effect between the stations indicated by item 101. The values ​​of items 201 and 202 are the same as the values ​​of items 101 and 102 of the delay recovery effect information 100 shown in FIG.

[0036] Item 203 indicates the allocation time (Time A) of the slack time based on the delay recovery effect. The value of item 203 is calculated by the slack time allocation determination unit 13 by allocating the slack time that can be allocated as the delay recovery effect between stations in accordance with the delay recovery effect between stations (the value of item 202) indicated in the delay recovery effect information.

[0037] Item 204 indicates the allocation time (Time B) of slack time based on the energy characteristics. The value of item 204 is calculated by the slack time allocation determination unit 13 by allocating the slack time that can be allocated as the energy characteristic portion between each station in accordance with the energy characteristics between each station indicated in the energy characteristic information (see FIG. 2).

[0038] The "slack time that can be allocated to the delay recovery effect" and the "slack time that can be allocated to the energy characteristics" are calculated by dividing the total amount of slack time that can be allocated according to the "division ratio" described above.

[0039] Item 205 indicates the slack time (Total Time) that is ultimately allocated between stations. The value of item 205 is calculated by the slack time allocation determination unit 13 by adding up the value of item 203 and the value of item 204.

[0040] As shown in FIG. 4, the slack time distribution determination unit 13 can determine the distribution of slack time between stations based on two pieces of constraint information, namely, energy characteristics and delay recovery effect.

[0041] In this embodiment, the slack time distribution determination unit 13 is not limited to determining the allocation of slack time between stations based on two pieces of constraint information, namely, energy characteristics and delay recovery effect, but may also determine the allocation of slack time between stations by adding or replacing other constraint information.

[0042] For example, the third constraint information may include the degree of punctuality requirement depending on the number of users (number of passengers). Specifically, a constraint is added to fix the required travel time or not to delay it for inter-station sections in a boarding section with many users. In this case, a large amount of slack time may be preferentially given to inter-station sections in a section with high passenger demand. Furthermore, for inter-station sections in a section with high passenger demand, slack time may be given in advance to the inter-station section, and the required travel time may be fixed by excluding the inter-station section in question from the inter-station sections to which slack time is allocated by the slack time distribution determination unit 13.

[0043] Furthermore, for example, a request to avoid the impact on subsequent trains due to the addition of slack time may be added as the fourth constraint information. The impact on subsequent trains due to the addition of slack time refers to a situation in which, as a result of train 20 slowing down between stations to which slack time has been added, subsequent trains are forced to slow down as well. Therefore, when the fourth constraint information is added, the slack time distribution determination unit 13 needs to allocate slack time to each station in the operation of train 20 while ensuring the punctuality of subsequent trains. Note that the slack time threshold (limit time) that can avoid the impact on subsequent trains can be calculated in advance for each station based on past performance data, simulations, etc.

[0044] When the fourth constraint information is incorporated, the slack time allocation determination unit 13 may consider restricting the slack time allocated to stations between which subsequent trains are likely to be affected. Alternatively, conversely, it may allocate a large amount of slack time between stations between which subsequent trains are likely to be affected, so as to achieve excellent energy characteristics, under the condition that delays are allowed within a range that does not affect subsequent trains. As a result, the on-time performance of subsequent trains may be improved. sex While maintaining this, it is possible to improve the delay recovery effect or energy characteristics (energy saving effect) of current trains.

[0045] In addition, information regarding the above-mentioned other constraint information (third constraint information, fourth constraint information) may be stored in the energy characteristics memory unit 11 or the delay recovery effect memory unit 12 in the diagram creation device 10, or may be stored in another memory unit.

[0046] The diagram creation unit 14 has a function of creating a diagram based on the slack time between stations determined by the slack time distribution determination unit 13. Specifically, the diagram creation unit 14 sets the target running time between stations (i.e., the target diagram) as a value obtained by adding the slack time between stations determined by the slack time distribution determination unit 13 to the fastest time between each station. Since a conventional general diagram creation function can be used for the diagram creation process after the target diagram for each station is set, a detailed explanation will be omitted.

[0047] The train 20 is a railway vehicle that runs according to the diagram created by the diagram creation device 10, and includes at least an operation control device 21.

[0048] The operation control device 21 has a function of controlling the running of the train 20 so as to meet the target running time in accordance with the timetable created by the timetable creation unit 14. Specifically, the operation control device 21 creates a plurality of speed targets (running patterns) and controls the operation of the train so as to follow one of the running patterns based on the target running time of the timetable.

[0049] The traffic management device 30 has a function of managing the operation of the train 20. For example, the traffic management device 30 controls the route of the train 20 at each station by controlling ground equipment (for example, the direction of switches) in order to make the train 20 proceed on the track specified in the timetable. Furthermore, when a change in the operation status occurs due to a delay of a preceding train or the like and a change from the originally created timetable becomes necessary, the traffic management device 30 instructs the timetable creation device 10 to re-create the timetable and notifies the train 20 of the re-created timetable by the timetable creation device 10. Alternatively, the traffic management device 30 may re-create the timetable based on the current situation and notify the train 20. In these cases, the traffic control device 21 of the train 20 controls the running of the train 20 in accordance with the re-created timetable.

[0050] The running pattern for running the train 20 may be calculated by the operation control device 21 as described above, or the results calculated by the operation management device 30 may be notified to the train 20 (operation control device 21).

[0051] Next, a procedure for creating a diagram in the train control system 1 according to this embodiment will be described.

[0052] 5 is a flowchart showing an example of a processing procedure for a diagram creation process. The diagram creation process is executed by the diagram creation device 10. The processing in FIG. 5 is executed, for example, before the train 20 starts operating.

[0053] According to FIG. 5, first, the slack time distribution determination unit 13 calculates the total value of slack times between all stations on the line for which a timetable is to be created (step S11).

[0054] Next, the slack time distribution determination unit 13 divides the total value of the slack time calculated in step S11 into a slack time allocated to the delay recovery effect and a slack time allocated to the energy characteristic in accordance with a predetermined division ratio (step S12). sex If there is any constraint information other than the energy characteristics and the delayed recovery effect, the value is determined taking into consideration this constraint information.

[0055] Next, the slack time distribution determination unit 13 distributes the slack time to be allocated to the delay recovery effect calculated in step S12 among the stations in accordance with the delay recovery effect among the stations indicated by the delay recovery effect information stored in the delay recovery effect storage unit 12 (step S13). In step S13, the slack time distribution determination unit 13 distributes the slack time among all the stations in accordance with the level of the delay recovery effect (see item 203 in Fig. 4).

[0056] Next, the slack time distribution determination unit 13 distributes the slack time to be allocated to the energy characteristic portion calculated in step S12 among the stations in accordance with the energy characteristics among the stations indicated by the energy characteristic information stored in the energy characteristic storage unit 11 (step S14). In step S14, the slack time distribution determination unit 13 distributes the slack time among all the stations in accordance with the level of energy saving performance (see item 204 in Fig. 4).

[0057] Next, the diagram creation unit 14 adds up the slack time allocated in step S13, the slack time allocated in step S14, and the fastest time between the stations for each interval, sets the total value as the target running time between the stations, and creates a target diagram for the line (step S15). The created diagram is notified to the train 20 and the traffic management device 30, and the diagram creation process ends.

[0058] The above is the procedure for creating a timetable in the train control system 1 according to this embodiment. By executing the timetable creation process before the operation of the train 20 as described above, in the allocation of required times with emphasis on energy conservation, when creating the timetable before operation, a large amount of slack time is preferentially allocated between stations with a high delay recovery effect, so that even if a delay occurs during operation, the probability that the delay can be recovered using the slack time can be increased, which is expected to have the effect of maintaining punctuality.

[0059] The diagram creation process shown in FIG. 5 may also be executed when a delay occurs while the train 20 is in operation. In this case, the slack time distribution determination unit 13 reallocates the total currently remaining slack time between each station included in the currently remaining section (i.e., each station between the current location of the train 20 and the terminal station) as a target for granting slack time. The diagram creation unit 14 then recreates the diagram based on the slack time and fastest time reallocated between each station. By executing the diagram creation process while the train 20 is in operation in this way, the remaining slack time is collected and reallocated so that more slack time is given preferentially between stations that have a high delay recovery effect while taking energy conservation into consideration. This enables the reallocation of required time according to the operating situation, which is expected to increase the probability of using slack time to recover from delays in subsequent operations and maintain punctuality.
