  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the operation arrangement support device in the railway operation management system will be described as an application target.

  FIG. 1 shows an example of an overall configuration diagram of a driving arrangement support system. The driving arrangement support system 1 according to the present embodiment is configured on the computer system and computer program of the driving arrangement support apparatus 1000, and includes a database 1100 that stores data such as a diagram, a calculation unit 1200 that executes the program, and an input from a user. Input device 1300 that accepts and an output device 1400 that displays a diagram or the like to the user. Further, the operation arrangement support device 1000 manages the traveling of the train 6 through the network 3 in cooperation with the on-site equipment of the switch 4 and the traffic light 5 from the interlock device 2.

  The database 1100 includes a schedule data table 1110 that holds schedule data for each train and destination platform, and schedule length of each train. A train data table 1120 to be stored and a line data table 1130 to store the line length of each platform are stored. Note that the information stored in the database 1000 is stored in a data server (not shown) connected to the network, and may be called to a computer as necessary.

  The computing unit 1200 reads the stored information in the database 1100 and executes a program or the like. The arithmetic unit 1200 may be called a CPU (Central Processing Uint). In the present embodiment, the prediction calculation unit or the like of the calculation unit 1200 means a program, and the calculation unit 1200 executes a program such as the prediction calculation unit, thereby enabling various functions of the driving arrangement support system 1 to be realized.

  The input device 1300 is an input device such as a mouse and a keyboard similar to a normal computer. The output device 1400 is an output device such as a display.

  FIG. 2 shows a block diagram of the arithmetic unit 1200.

  The calculation unit 1200 is created by a prediction calculation unit 1210 that calculates a predicted time of train travel, a driving arrangement proposal unit 1220 that automatically creates a driving arrangement plan that can be delayed from the calculated predicted time, and a driving arrangement proposal unit 1220. A driving arrangement plan 1230 for processing the driving arrangement proposal or the driving arrangement plan input from the input device 1300, displaying information necessary for the driving arrangement, and changing the diagram data table based on the executed driving arrangement plan; A line change possibility determination processing unit 1240 that determines whether or not accommodation to a platform as a change destination candidate is possible at the time of operation arrangement plan creation, and information that supports operation arrangement such as a diagram, a train length, and a line length to the output device 1400 An information display unit 1250 to be displayed and a traveling management unit 1260 for grasping the traveling state of the train and updating the actual schedule.

  FIG. 3 is a diagram showing an example in which four trains (train A131, train B132, train C133, train D134) travel in the same station. A specific example will be described with reference to FIG.

  Train A131 arrives at Platform1 after the planned arrival time and stops. Train B132 stops outside the planned destination Platform1, and train C133 arrives at Platform2 according to the planned arrival time. However, the train D134 has arrived at Platform 3 according to the planned arrival time and is in a stopped state.

  At this time, it is assumed that the train B132 is planned to travel to Platform1, which is the destination platform. However, since train A131 has already stopped at Platform1 due to the delay, train B132 cannot travel to Platform1 until train A131 departs, and train B132 is in a state of waiting for departure of train A131. As a result, it is predicted that the train B132 also causes a travel delay in the same manner as the train A131.

  Here, as an operation arrangement plan for eliminating the travel delay of the train B132, Platform2, which is another platform having a marginal space length capable of accommodating the train B132, is changed as an arrival destination. Thereby, the delay of the train B132 can be reduced. Since Platform 3 does not have a marginal space length that can accommodate the train B132, it cannot be changed as an arrival destination.

  In other words, in this embodiment, when a train traveling delay occurs, the platform having a marginal space length that can accommodate the delayed train is changed as an arrival destination as an operation arrangement plan for eliminating the delay, so that the delayed train Can travel outside the platform without stopping. Furthermore, it is possible to reduce the influence of the delay that propagates to other trains that follow the delayed train, and it is possible to realize a more efficient transportation operation.

  FIG. 4A is a diagram illustrating an example of a diagram table 1110 in the present embodiment. The diagram table 1110 includes a plan diagram 1111 indicating an initial train travel plan, an actual diagram 1112 indicating actual train travel results, a prediction diagram 1113 predicting future train travel, and a temporary diagram 1114 created during operation arrangement. Remember. Each diagram in the diagram table 1110 stores a train number, a platform number to be called, a train arrival time and a departure time. Here, the current time in the present embodiment is 12:00.

  The record diagram 1112 is created by the travel management unit 1260 when the train arrives or departs from the platform.

  Train A arrives at Platform 1 at 11:58 from the actual schedule 1112. This is a delay of 4 minutes from 11:54, which is the arrival time of the planned schedule.

  A prediction diagram 1111 is created by the prediction calculation unit 1210 from the train running results. Here, when the prediction diagram (before operation organization) when delay reduction measures such as operation organization described in Fig. 4-1 are not taken is seen. The predicted arrival time of train B is 12:03, and a delay of 3 minutes has occurred from 12:00, which is the arrival time of the schedule of train B.

  This is because Train B is forced to stop outside the platform until Train A, which is stopped at the destination platform, leaves the platform, that is, until 12:02.

  FIG. 4-2 is a diagram illustrating an example of a train data table 1120 in the present embodiment. The train data table 1120 stores the train length of each train.

  FIG. 4-3 is a diagram illustrating an example of the number line data table 1130 in the present embodiment. The line number data 1130 stores the line length of each line (platform) of the station.

  Next, processing of each unit of the calculation unit 1200 will be described.

  As shown in FIG. 5, the calculation unit 1200 activates the prediction calculation unit 1210 and calculates the predicted time of train travel (S1) (details will be described later in FIG. 6). Next, the calculation unit 1200 performs either a process for automatically creating a driving arrangement plan or a process for manually creating a driving arrangement plan (S2).

  When the operation arrangement plan is created manually, the operation arrangement unit 1230 reads the train selected from the input device 1300 (S3), and determines that the read train is a train to be changed on the line for performing operation arrangement (S4). Next, the number change possibility determination processing unit 1240 determines whether or not the number change target train can be accommodated in a platform that is a change destination candidate (S6) (details will be described later in FIG. 8).

  When the operation arrangement plan is automatically created, the operation arrangement proposal unit 1220 selects a train for changing the number of lines to be arranged for operation arrangement from the calculated predicted time (S5) (details will be described later in FIG. 7). At this time, the number change possibility determination processing unit 1240 determines whether the number change target train can be accommodated in the change destination candidate platform according to the train occupation status of the platform that is the change destination candidate of the number change target train ( S6) (Details will be described later in FIG. 9).

  After the process for determining whether or not the line can be changed, the operation arrangement unit 1230 creates an operation arrangement plan (S7). Then, the information display unit 1250 displays on the output device 1400 information for assisting operation organization, such as the schedule, train length, train occupancy status of the change destination candidate platform, and the necessity of executing the operation organization plan (S8, S9). ). If it is necessary to execute the route arrangement plan, the operation arrangement unit 1230 reflects the operation arrangement plan on the diagram table (S10).

  As shown in FIG. 6, the prediction calculation unit 1210 reads the planned schedule and the actual schedule defined for each train (S101), calculates the difference between the arrival time and the departure time of the planned and actual diagrams (S102), and each train. The platform arrival prediction time and platform departure prediction time are calculated (S103), and the calculated prediction time is written in the diagram data table to create a prediction diagram (S104).

  For example, if a train arrives at the platform 2 minutes behind the planned time, the difference between the planned time and the actual time will be 2 minutes, and the arrival time of the next platform of this train will be Create a prediction diagram with a 2 minute delay. This operation is performed at a certain cycle.

  As shown in FIG. 7, the operation arrangement proposal unit 1220 reads the planned time and actual time of each train (S201), compares the arrival time or departure time of each train with the predicted time, and calculates the difference (S202). ), It is determined whether the difference is greater than or equal to a certain time (α) (S203). If the difference is greater than or equal to a certain time (α), it is determined that the train has a delay, and an operation arrangement plan is created by changing the number line to eliminate the delay (S204). When preparing a driving arrangement plan by changing the number of lines, a number of lines can be changed / decisioned for determining whether or not the number of lines can be changed to each platform where the delayed train is a candidate for changing the number of lines. The unit 1240 is called (S205), and when it is determined that the line change to the platform is possible, the operation arrangement proposal unit 1220 creates an operation arrangement plan that is a temporary diagram (S206). Thereafter, the operation arranging unit 1230 for executing the created operation arrangement plan is activated (S207).

  The driving arrangement unit 1230 implements the driving arrangement plan created by the driving arrangement proposal unit. Further, the user operation information input by the input device 1300 is read, and the number change determination unit 1240 and the information display unit 1250 are executed according to the operation. Furthermore, the operation arrangement plan created by the input device 1300 is executed.

  In addition, the operation arranging unit 1230 includes the following items based on (1) an operation arrangement plan manually created by the input device 1300 and (2) an operation arrangement plan automatically created by the operation arrangement proposal unit 1220. Process.

  (1) The operation arrangement plan created by performing the manual operation arrangement operation on the input device 1300 is transmitted to the information display unit 1250, and a temporary diagram reflecting the result of the operation arrangement is displayed on the output device 1400.

  (2) The driving arrangement plan created by the driving arrangement proposal unit 1220 is transmitted to the information display unit 1250, and a temporary diagram reflecting the result of the driving arrangement is displayed on the output device 1400.

  The user confirms the reflection result of the displayed driving arrangement plan, and operates the input device 1300 to instruct the driving arrangement unit 1230 to execute or cancel the driving arrangement. When the user executes the driving arrangement displayed on the output device 1400, the driving arrangement unit 1230 reflects the displayed driving arrangement plan in the diagram data table.

  The number change possibility determination unit 1240 determines the train occupancy status of the platform that is the candidate for the change destination of the number change target train. Specifically, it is determined whether or not the platform that is the candidate for change destination has a marginal space length that can accommodate the train for changing the line, that is, whether or not it has an empty space. It is assumed that when the platform as the change destination candidate has a marginal space length and it is evaluated that the train for changing the number of lines can be accommodated, the operation can be organized by changing the number of lines. Details will be described with reference to FIG. 8 in the case of manual driving arrangement operation and FIG. 9 in the case of automatic driving arrangement operation.

  The information display unit 1250 is a current time, a plan diagram, a prediction diagram, a temporary diagram, a wire length, a train length, whether or not the train can be accommodated in a number change destination candidate at the time of operation arrangement, an operation arrangement execution / cancellation dialog, and a change destination candidate. Information that assists in the operation arrangement such as the train occupation status of the platform is displayed on the output device 1400.

  The traveling management unit 1260 writes the time when the train defined in the diagram data table arrives at the platform or leaves the platform in the actual diagram of the diagram data table 1110. Until the train arrives at or departs from the platform, the arrival time and departure time of the actual schedule will be empty.

  FIG. 10 shows a screen example 1 of the output device 1400 before the operation organization by the diagram in this embodiment.

  In the present embodiment, the diagram is represented on the screen plane 201, the horizontal axis represents time, the vertical axis represents the travel position, and the screen left side 202 represents the station name and each platform in the station. The diagram is displayed so that the prediction diagram and the planning diagram can be identified. For example, the dotted line indicates the prediction diagram, and the solid line indicates the planning diagram. In addition, when the plan diagram and the prediction diagram match, they are displayed in an overlapping manner. Specifically, a dotted line indicates a prediction diagram 221 for train A, a prediction diagram 222 for train B, and a solid line indicates a plan diagram 211 for train A and a plan diagram 212 for train B. Moreover, since the plan diagram of the train C and the train D and the prediction diagram (223, 224) coincide, they are displayed in an overlapping manner.

  The information display unit 1250 obtains from the computer system or the system setting time, and displays the current time on the output device 1400. As in this embodiment, the current time may be displayed at 12:00 and the time display 203, or one point may be displayed as the time 204 on the horizontal axis.

  The information display unit 1250 acquires the schedule diagram 1111 of each train from the diagram table 1110 at a certain period, and displays the schedule diagram 1111 of each train on the output device 1400.

  The information display unit 1250 acquires the prediction diagram 1113 of each train from the diagram table 1110 at a certain period, and displays the prediction diagram 1113 of each train on the output device 1400 with a dotted line.

  The information display unit 1250 displays, on the output device 1400, a chain line indicating the time in 2 minutes on the horizontal axis.

  FIG. 12 shows an example of manual operation rearranging operation in screen example 1 using a diagram in the present embodiment.

  Screen example 1 of the present embodiment displays screen 201 on the screen plane, screen left side 202, current time display (203, 204), and diagrams (211, 212, 221, 222, 223, 224) as in FIG. .

  When the train is selected 241 by the user using the input device 1300, for example, when the user moves the mouse pointer over the train prediction diagram 222 (mouse over), the operation organizing unit 1230 selects the selected train prediction diagram. The train length of 222 train B is acquired from the train data table 1120. The driving arrangement unit 1230 transmits an instruction to display the acquired train length to the information display unit 1250. Then, the information display unit 1250 displays the acquired train length 242 of the train B on the output device 1400.

When the user selects 241 a prediction diagram 222 of a train for which a track record of arrival at a platform defined as an incoming / outgoing platform is not created in the diagram table 1110 using the input device 1300, for example, the user continues to click with a mouse operation. (Pick)
The driving arrangement unit 1230 determines that the picked-up train is the target for changing the number line, and executes the number line change possibility determination processing unit 1240.

  As shown in FIG. 8, the processing flow of the number change possibility determination processing unit 1240 when manually organizing driving will be described.

  The number change possibility determination processing unit 1240 determines whether or not the number change of platform / time that is a candidate for the number change destination of the picked train is possible.

  The number change possibility determination processing unit 1240 determines whether each platform as a change destination candidate can accommodate a number change target train at each time after the current time.

  The number change possibility determination unit 1240 is predicted to stop at the change destination candidate platform at each time, or stop on the prediction diagram, at the change destination candidate platform defined in the number line data table 1130. The train length of the train is read (S301), and a value obtained by further subtracting the minimum inter-vehicle distance from the difference between the line length and the train length is calculated as a margin space length (S302).

  When this marginal space length is equal to or greater than the train length of the train for changing the number of lines defined in the train data table, the train for changing the number of lines can be accommodated in the platform that is the candidate for change (S303, S304).

  When this marginal space length becomes a value equal to or less than the train length of the train for changing the number of lines defined in the train data table, the train for changing the number of lines cannot be accommodated in the platform that is the candidate for change (S303, S305).

  Furthermore, when there are other trains that have already stopped among the platforms that cannot be accommodated (S306), it is impossible to accommodate until the time when the minimum departure waiting time is added to the departure time of this train (S307). .

  The minimum inter-vehicle distance indicates a distance to be maintained between trains, and is assumed to be 10 m in this embodiment.

  The minimum departure waiting time cannot be defined as a schedule with a departure time within a certain period of time immediately after another train that has already stopped or is predicted to stop, In a platform that cannot be accommodated for a short time, it shows the time when it is not possible to define a timetable that arrives within a certain period of time immediately after the other train that has already stopped or is predicted to stop, In the present embodiment, this is assumed to be 1 minute.

  Next, the information display unit 1250 is activated (S308).

  The information display unit 1250 has a train that is already stopped or a train that is predicted to stop on the prediction diagram for the platform / time determined by the number change change determination processing unit 1240 to be able to accommodate the number change target train. If not, the platform / time determined to be able to accommodate the train to be changed is displayed on the output device 1400 as a dot pattern rectangle 251.

  The information display unit 1250 has a train that is already stopped or a train that is predicted to stop on the prediction diagram for the platform and time determined to be able to accommodate the train for change of the number by the number change determination unit 1240. If it exists, the platform / time determined to be able to accommodate the train to be changed is displayed on the output device 1400 as a mesh rectangle 252.

  The information display unit 1250 outputs, as a hatched rectangle 253, the platform / time at which the number change train is determined to be unacceptable by the number change change determination processing unit 1240. Display on device 1400.

  At this time, each of the quadrilaterals shown above is displayed with a different color pattern or color, or a color and a pattern so that they can be identified. In this embodiment, each square is identified by a different pattern.

  In addition, the information display unit 1250 may perform highlight display for the platform / time determined by the number change possibility determination processing unit 1240 that the number change target train can be accommodated.

  Operator operability can be improved by distinguishing the display of platforms and times determined to be able to accommodate trains depending on the presence or absence of trains on the line.

  The information display unit displays the train so that the user can identify that the train can be accommodated or cannot be accommodated in the platform of the change destination candidate.

  In the input device 1300, when the user drags the train prediction line by mouse operation and drops it to the platform / time determined to be changeable, the operation organizing unit 1230 changes the number to the platform where the dragged train is dropped. A temporary diagram obtained as a result of the change of the wire number is created.

  The temporary diamond to be created is set to the platform dropped on the destination platform of the train. In addition, the time at the position of the mouse pointer is set as the arrival time of the train. Furthermore, as the departure time of the train, a time obtained by adding a stop time that is a difference between the departure time and the arrival time on the planned schedule of the train to be changed to the arrival time to the arrival time is set. However, if another train that is already stopped exists and cannot be departed at the set departure time, the departure time is set to a time obtained by adding the minimum departure waiting time to the predicted departure time of the other train. The temporary diamond created above is written in the temporary diamond table.

  For example, when the user is dragging a train prediction diagram by a mouse operation using the input device 1300, the operation organizing unit 1230 displays the train length of each platform at each time point on the mouse pointer 243, and each platform An instruction to display a margin space length obtained by further subtracting the minimum inter-vehicle distance from the difference from the number of the No. line is transmitted to the information display unit 1250. The information display unit 1250 displays a margin space length (231 to 232) with respect to the line length of each platform below each platform name on the output device 1400.

  The information display unit 1250 causes the output device 1400 to display a diagram 271 of the temporary diagram table. When the user enters the change target train on the line change target platform, the information display unit 1250 also displays the diagram of the temporary diagram table on the output device 1400 even when the change destination platform is in a transitional state. The transient state means that the total length of the train length of the train that is already in the destination candidate platform or the train that is predicted to be in the train and the train length of the train to be changed is greater than the length of the destination platform. Sure. That is, it is a case where the train subject to change of the line cannot be accommodated on the platform to be changed. As a result, even when the user mistakenly tries to enter the train to be changed to the change destination platform that cannot be accommodated, the change destination platform can be newly selected from the continuation. Therefore, user operability is improved.

  When using the input device 1300, for example, when the user drags a train prediction line by a mouse operation and drops it on a platform / time determined to be changeable, the operation arranging unit 1230 displays the operation arrangement in the display instruction table. The display instruction of the operation organization execution dialog for selecting execution / cancellation is transmitted to the information display unit 1250, and the information display unit 1250 displays the operation organization execution / cancellation dialog 261 on the output device 1400. At this time, a diagram that is a temporary diagram is displayed on the output device.

  For example, when the user clicks an execution button on the operation arrangement execution dialog by a mouse operation using the input device 1300, the operation arrangement unit 1230 selects the temporary schedule of the operation arrangement target train in the diagram data table 1110 as the operation arrangement target. Overwrite the train schedule.

  When the user clicks on the cancel button on the operation arrangement execution dialog by the mouse operation using the input device 1300, the operation arrangement unit 1230 deletes the temporary diagram of the operation arrangement target train from the temporary diagram table.

  As mentioned above, although embodiment of invention was described, the Example which performs a number line change with respect to the train B below is demonstrated.

  Here, the number of the platform 1 is 80 m, the number of the platform 2 is 100 m, and the number of the platform 3 is 100 m.

  First, the user picks the train B prediction diagram by operating the mouse. At this time, the driving arrangement unit 1230 executes a number change possibility determination processing unit 1240, and the number change possibility determination processing unit 1240 makes a number change possibility determination for Platforms 1, 2, and 3 that are candidate line change destinations.

  In the processing of the number change possibility determination processing unit 1240, Platform 1 has a current length of 12:00 to 12:03, and the train length of train A that is predicted to stop is 80m. 0m, which is 80m of train A minus 80m of train A, is the spare space length, and train B with train length of 50m cannot be accommodated.

  From 12:04 onwards for Platform1, there is no train that has been predicted to stop, so the line length of 80m for Platform1 becomes the extra space length as it is, and the train length of 50m for train B can be accommodated.

  Platform2 has already stopped Train C from 12:00 to 12:04, which is the current time, and the train C has a train length of 30m. The extra space length is 60m, which is 10m which is the minimum inter-vehicle distance from the drawn 70m, and the train B's 50m length can be accommodated.

  From 12:04 onwards, there is no train that has been predicted to stop, so the line length of 100m of Platform 2 becomes the extra space length as it is, and the train length of 50m of train B can be accommodated.

  Platform3 has already stopped train D from 12:00 to 12:10, which is the current time, and train D has a train length of 50m. 40m obtained by subtracting 10m, which is the minimum inter-vehicle distance, from the pulled 50m is the extra space length, and the train B's 50m length cannot be accommodated.

  From 12:10 onwards, there is no train that has been predicted to stop, so the line length of 100m on Platform 3 becomes the extra space length, and the train length of 50m can be accommodated for train B.

  Next, in a state where the train B prediction streak is picked by a mouse operation, the user drags it to a point on Platform 2 / time 12:00 determined that the number of lines can be changed. At this time, the operation arranging unit 1230 writes a temporary diamond having the departure time as 12:00 and the arrival time as 12:06, which is 6 minutes after the stop time on the planned schedule of train B, in the temporary diamond table. . In addition, the temporary display 271 of the train B is displayed on the output device 1400 by the information display unit 1250.

  When the mouse pointer is present at 12:00, the driving arrangement unit 1230 calculates the marginal space length of each platform at the time of 12:00, and the driving arrangement unit 1230 issues a display instruction for the marginal space length.

A screen left side 302 on the screen plane 301 shows a station name and each platform in the station. The display of the current time (303, 304) is displayed in the same manner as in screen example 1.

  In this embodiment, on the screen plane 301, the diagram for each train of the diagram table 1110 is represented by a train block shape (311, 312, 321, 322, 323, 324) simulating a train.

  The information display unit 1250 acquires the prediction diagram 1113 of the diagram table 1110 and displays the predicted train block shape (321, 322, 323, 324) of each train on the screen.

  The information display unit 1250 acquires the planned diagram 1111 of the diagram table 1110 and displays the planned train block shape (311, 312) of each train on the screen so that it can be identified from the predicted train block shape. Specifically, the planned train block shape is displayed on the screen after being subjected to a permeation process.

  The information display unit 1250 displays the tip of the train block-shaped side of the diamond table 1110 for each train so as to be the departure time of the platform on the diamond, and the train block-shaped notch The end of the side that does not exist is displayed so as to be the arrival time at the platform on the diagram. That is, the side with the diagonal notch of the train block shape indicates the traveling direction of the train, and here the traveling direction of the train is the right direction.

  The information display unit 1250 acquires the train length of each train from the train data table 1120 for all trains in the diagram table 1110, and displays the train block-shaped vertical axis on the screen so as to be the acquired train length.

  The information display part 1250 acquires the train name of the train corresponding to each train block form from the train data table 1120 for all trains in the diagram table 1110, and displays the train name on each train block form.

  On the screen, the platform is represented by a rectangular platform block shape (331, 332, 333).

  The information display unit 1250 acquires the number of each platform from the number data table 1130 and displays the platform block type (331, 332, 333) vertical axis on the screen so as to obtain the acquired number.

  On the screen, the horizontal axis of the platform block type indicates the time.

  When a plurality of trains stop at the same platform and the same time, the information display unit 1250 displays trains with earlier departure times on the screen in order from the top to the bottom of the platform block shape.

  Hereinafter, an example of displaying screen example 2 in the present embodiment will be described.

  The information display unit 1250 acquires each schedule of the train A, the train B, the train C, and the train D defined in the plan diagram 1111 and the prediction diagram 1113 of the diagram table 1110.

  Since the schedule of train A arrived at Platform 1 at 11:54 and departed from Platform 1 at 11:58, the platform block type of Platform 1 from 11:54 to 11:58 A train block shape 311 indicating the train A on the schedule is displayed on the screen.

  Since the schedule for train B arrives at Platform 1 at 12:00 and departs from Platform 1 at 12:06, the platform block type of Platform 1 is from 12:00 to 12:06 A train block shape 312 indicating the train B on the schedule is displayed on the screen.

  Since the schedule of train C arrived at Platform 2 at 11:52 and departed from Platform 2 at 12:04, the platform block type of Platform 2 from 11:52 to 12:04 A train block shape 323 indicating the train C on the schedule diagram is displayed on the screen.

  Since the schedule of train D arrived at Platform 3 at 11:45 and departed from Platform 2 at 12:04, the platform block type of Platform 2 from 11:52 to 12:10 A train block shape 324 indicating the train D on the schedule diagram is displayed on the screen.

  The prediction schedule of train A arrived at Platform 1 at 11:58 and departed from Platform 1 at 12:02, so the platform block type of Platform 1 from 11:58 to 12:02 A train block shape 321 indicating A on the prediction diagram is displayed on the screen.

  The prediction schedule for train B arrives at Platform 1 at 12:03 and departs from Platform 1 at 12:09, so the platform block type of Platform 1 from 12:03 to 12:09 A train block shape 322 indicating the train B on the prediction diagram is displayed on the screen.

Since the planned schedule and the predicted schedule of train C and train D match, the train block shape (323, 324) is displayed in an overlapping manner. Thus, in screen example 2, the vertical axis of each platform number and each train Because the train length and the time are displayed on the horizontal axis, the visibility of the extra space length at each platform and each time is improved, and simplification of operation and arrangement work can be expected.

  Further, trains with earlier departure times are displayed on the screen in order from the top to the bottom of the platform block shape so that the train block shapes do not overlap. As a result, even when there is a train that stops on the same platform at the same time, it is displayed above and below the platform range, so the visibility of the running status of each train can be improved.

  FIG. 13 shows an example of manual operation arrangement operation in screen example 2 in this embodiment.

  Screen example 2 of this embodiment is similar to FIG. 11, on screen plane 301, screen left side 302, current time display (303, 304), train block shape (311, 312, 321, 322, 323, 324). indicate.

  On the screen, when the user moves the mouse pointer 341 to a predicted train block shape indicating a predicted diamond train (mouse over), the operation arranging unit 1230 trains the train length of the predicted train block type train that has been moused over. Obtained from the data table 1120 and transmits an instruction to display the obtained train length to the information display unit 1250, and the information display unit 1250 displays the train length 342 on the screen.

  On the screen, when the user continues to click (pick) the predicted train block shape in which the actual arrival timetable to the platform defined as the arrival platform in the diamond table 1110 is not created (pick), the operation organizing unit 1230 The train being picked is determined to be the number change target, and the number change change determination processing unit 1240 is executed. The number change possibility determination processing unit 1240 determines whether or not the number change of platform / time that is a candidate for the number change destination of the picked train is possible. The determination on whether or not the number line can be changed is the same as the determination on whether or not the number line can be changed in the embodiment shown in FIG.

  When the platform / time is determined to be able to accommodate the trains subject to change of the number of lines by the number change change determination processing unit 1240 (351, 352), and the trains subject to change of the routes cannot be accommodated. When the platform / time determined to be displayed (353) is the same as the case where the operation arranging unit 1230 in the embodiment shown in FIG.

  Further, the information display unit 1250 displays the minimum inter-vehicle distance 100 as a rectangle 3300 shown in FIG.

  When using the input device 1300, for example, when the user picks the predicted train block shape by operating the mouse and drags it to the platform / time determined to be changeable, the operation organizing unit 1230 displays the dragged train. Judge that it is going to change the line to the dragged platform, and create a temporary diagram obtained as a result of the change of the line. The temporary diamond is the same as the temporary diamond creation method described in FIG.

  For example, when the user drags the predicted train block shape 322 from the mouse pointer 341 to the mouse pointer 343 by operating the mouse using the input device 1300, the marginal space length (331, 332, 333) to the output device 1400, the temporary diagram The display method of the train block shape 371 is the same as the method described in FIG.

  When the input device 1300 is used to drag the predicted train block shape by the mouse operation and drop it to the platform / time determined to be able to change the line, the operation arrangement execution / cancellation dialog to the output device 1400 The display method 361 and the processing after the execution / cancellation input of operation arrangement are the same as the method described in FIG.

  The user clicks the execution button of the operation arrangement execution dialog. At this time, the screen display is switched from the upper diagram of FIG. 13 to the lower diagram.

  The operation arranging unit 1230 writes the temporary diagram of the train B as the planned diagram of the train B, and the information display unit 1250 displays the planned train block type and the predicted train block type (381) of the train B. At this time, the temporary diagram is written as a plan diagram by the operation arrangement, and the plan diagram and the prediction diagram coincide. Thereby, the operation arrangement of the train B is completed.

  FIG. 14 is a diagram showing an example of automatic driving arrangement by a diagram in the present embodiment.

  Description of the screen example of this embodiment is omitted for the same parts as in FIG. Diagrams (211, 212, 221, 222, 223, 224) displayed in the screen example are the same as those in FIG. 10.

  The prediction calculation unit 1210 executes processing as described with reference to FIG. 5 at a certain period.

  Next, the driving arrangement suggestion unit 1220 executes processing as described with reference to FIG. 6 at a certain period. Here, if there is a train with a difference of a certain time or more between the planned schedule and the predicted schedule, the train is judged to have a delay, and an operation arrangement plan is created with that train as the operation arrangement target train. The operation arrangement | positioning part 1230 to perform is started.

  The driving arrangement unit 1230 activates the number change possibility determination processing unit 1240.

  The number change possibility determination processing unit 1240 determines whether or not the train for operation rearrangement can be accommodated on each platform that is a candidate for change destination, with the train for change of operation number being the change target train.

  As shown in FIG. 9, the number change change determination processing unit 1240 starts a number change search loop (S401).

  The number change possibility determination processing unit 1240 determines that the number change is impossible when the number change target train has arrived at the platform at the current time (S402, 407).

  The number change possibility determination processing unit 1240, when the number change target train has not arrived at the platform, at each time in the future from the current time, from the platform length of the platform as the change destination candidate defined in the number line data table 1130 The value obtained by subtracting the train length of the train that is predicted to stop on the prediction schedule in the diagram data table 1110, and further subtracting the minimum inter-vehicle distance is set as the marginal space length. Calculate (S403, S404).

  When the marginal space length is equal to or greater than the train length of the number change train, the number change train can be accommodated in the platform that is the change destination candidate (S405, S406).

  When the marginal space length becomes smaller than the train length of the number change train, the number change train is not allowed to be accommodated in the platform that is the change destination candidate (S405, S407).

  The number change possibility determination processing unit 1240 uses the platform / time when the number change target train can be accommodated as the arrival / departure platform / arrival time. When there is no other stopped train, the departure time is determined by adding the stop time on the planned schedule of the train to be changed to the arrival time to the arrival time. If there are other trains that have already stopped, the minimum departure waiting time is set at the estimated departure time of the other trains that have already stopped, from the time obtained by adding the stop time on the schedule of the target train to be changed to the arrival time. If the added time is later, the latter time is set as the departure time. Based on the arrival time and the departure time, a temporary diagram of the train to be changed is created and written in the temporary diagram table of the diagram table 1110 (S408).

  The number change change determination processing unit 1240 activates the information display unit 1250 (S409), and ends the number change search loop (S410).

  The operation organizing unit 1230 acquires the temporary diagram table of the diagram table 1110, compares the temporary diagram of the train to which the line is changed and the predicted diagram of the train to which the train is changed, and is later than the arrival time from the predicted diagram of the train to which the line is changed. The temporary diamond that is the arrival time is deleted from the temporary diamond table.

  Thereafter, the operation arranging unit 1230 compares the temporary diagram of the train for changing the line with the planned diagram of the train for changing the line, and selects the temporary diagram whose departure time is closest to the planned diagram of the train for changing the line. The driving arrangement unit 1230 transmits a diagram display instruction for the selected temporary diamond to the information display unit 1250. The information display unit 1250 displays a temporary diamond diagram 471 on the output device 1400.

  The subsequent processing is the same as in the case of manual operation arrangement described with reference to FIG.

  The driving arrangement unit 1230 transmits a display instruction for the driving arrangement execution dialog to the information display unit 1250, and the information display unit 1250 displays an execution / cancellation dialog 261 for driving arrangement on the output device 1400.

  For example, when the user clicks an execution button on the operation arrangement execution dialog by a mouse operation using the input device 1300, the operation arrangement unit 1230 selects the temporary schedule of the operation arrangement target train in the diagram data table 1110 as the operation arrangement target. Overwrite the train schedule. At this time, the output device switches to the following diagram and displays a diagram 481 which is a temporary diagram.

  When the user clicks the execute button on the operation arrangement execution dialog 261 by the mouse operation using the input device 1300, the operation arrangement unit 1230 overwrites the temporary diagram of the train to be changed to the schedule diagram of the operation arrangement object train. To do.

  When the user clicks the cancel button on the operation arrangement execution dialog 261 by the mouse operation using the input device 1300, the operation arrangement unit 1230 deletes the temporary diagram of the train for which the line is changed from the temporary diagram table.

  Although the embodiment of the invention has been described above, an example in which automatic operation arrangement is performed for the train B having a train length of 50 m will be described below.

  Here, it is assumed that the number of the platform 1 is 80 m, the number of the platform 2 is 100 m, and the number of the platform 3 is 100 m.

  First, the operation arrangement proposing unit 1220 compares the planned diagram and the predicted diagram of the train A on the diagram table 1110.

  The schedule for Train A is scheduled to arrive at Platform 1 at 11:54 and depart at 11:58.

  The prediction schedule for train A is predicted to arrive at Platform 1 at 11:58 and depart at 12:02.

  Here, since the train A has a difference of 4 minutes between the plan diagram and the prediction diagram, the operation arrangement proposal unit 1220 activates the operation arrangement unit 1230 with a delay in the train A.

  The driving arrangement unit 1230 activates the number change possibility determination processing unit 1240, and the number change possibility determination processing unit searches for the number change destination candidate of the train A with the train A as the number change target train. Since it has already arrived at Platform 1 at the time of 12:00, the process is terminated with no number change destination.

  Next, the operation arrangement proposing unit 1220 compares the planned diagram and the predicted diagram of the train B in the diagram table 1110.

  The schedule for train B is scheduled to arrive at Platform 1 at 12:00 and depart at 12:06.

  The prediction schedule for train B is predicted to arrive at Platform 1 at 12:03 and depart at 12:09.

  Here, since the train B has a difference of 3 minutes between the plan diagram and the prediction diagram, the operation arrangement proposal unit 1220 activates the operation arrangement unit 1230 with a delay in the train B.

  The driving arrangement unit 1230 activates the number change possibility determination unit 1240. The number change possibility determination processing unit 1240 determines whether or not the train B can be accommodated in Platform 1, Platform 2, and Platform 3, which are number change destination candidates.

  The number change possibility determination processing unit 1240 determines whether or not the train B can be accommodated in the platform as the change destination candidate at each time after 12:00, which is the current time.

  From Platform 1 to 12:00 to 12:02, Train A stops, Platform 1's line length is 80m, Train A's train length is 80m, so the marginal space length is assumed to be 0m. At time, train B cannot be accommodated on Platform1.

  At the time after 12:02, there is no train that is stopped and a train that is predicted to stop, so the marginal space length is 80 m. Even if subtracting 50 m of the train B's train length from the surplus space length, a 30 m surplus remains, so that train B can be accommodated in Platform 1 at this time.

  The line change possibility determination processing unit 1240 uses the time after 12:02 of Platform 1 as the arrival / departure platform / arrival time, and from the time after 12:02, 6 minutes, which is the stop time on the schedule of train B, is obtained. A temporary diamond of train B having the added time as the departure time is created and written in the temporary diamond table of the diamond table 1110.

  In Platform2, train C stops from 12:00 to 12:04, the length of Platform 2 is 100m, and the length of train C is 30m, so the extra space length is the length of Platform 2 It is 60m, which is 100m from 70m minus the train length of 30m, and further minus the minimum inter-vehicle distance of 10m. Even if the train length of 50m is subtracted from the surplus space length, a margin of 10m remains, so train B can be accommodated in Platform 2 at this time.

  At the time after 12:04, there is no train that has stopped and a train that is predicted to stop, so the marginal space length is 100 m. Even if the train length of 50m is subtracted from the surplus space length, a surplus of 50m remains, so train B can be accommodated in Platform 2 at this time.

  The number change possibility determination processing unit 1240 uses the time after 12:00 of Platform 2 as the arrival / departure Platform / arrival time. The time obtained by adding 6 minutes, which is the stop time on the schedule of train B, from the time after 12:00 is taken as the departure time. From this, a temporary diamond of train B is created and written to the temporary diamond table of diamond table 1110.

  Since the train D is stopped at Platform3 from 12:00 to 12:10, the length of the line 3 of Platform3 is 100m and the length of the train D is 50m, the marginal space length is 100m of the length of Platform3 The train length is 40m, which is 50m minus the train length of train D, minus the minimum inter-vehicle distance of 10m. At this time, train B cannot be accommodated in Platform1.

  At the time after 12:10, there is no train that is stopped or a train that is predicted to stop, so the marginal space length is 100 m. Even if the train length of 50m is subtracted from the surplus space length, a surplus of 50m remains, so train B can be accommodated in Platform 3 at this time.

  The number change possibility determination processing unit 1240 uses the time after 12:10 of Platform 1 as the arrival / departure time. The time obtained by adding 6 minutes, which is the stop time on the schedule of train B, from the time after 12:10 is taken as the departure time. As a result, a temporary diamond of train B is created and written to the temporary diamond table of diamond table 1110.

  The operation arranging unit 1230 acquires the temporary diamond table of the diamond table 1110, compares the temporary diamond of train B with the predicted diamond of train B, and arrives later than 12:03, which is the arrival time of the predicted diamond of train B. Temporary diamonds arriving at Platform 1 and Platform 3, which are the times, and temporary diamonds with arrival times after 12:03 of Platform 2 are deleted from the temporary diamond table.

  After that, the operation arranging unit 1230 compares the temporary schedule of the train B of the temporary schedule table with the planned schedule of the train B, and arrives at Platform 2 at 12:00, where the departure time is closest to the planned schedule of the train B. , Select a temporary diamond that leaves Platform2 at 12:06.

  The driving arrangement unit 1230 transmits a diagram display instruction for the selected temporary diamond to the information display unit 1250. The information display unit 1250 displays a temporary diamond diagram 471 on the output device 1400.

  Next, the operation organizing unit 1230 transmits to the information display unit 1250 a display instruction for an operation organizing dialog that asks whether or not the operation organizing of the train to be changed is set as the selected temporary schedule. The information display unit 1250 displays an operation arrangement execution dialog 261 that asks the output device 1400 whether or not the operation arrangement needs to be executed.

  When the user selects an execution button on the operation organization execution dialog 261 using the input device 1300, the operation organization unit 1230 overwrites the train B's temporary diagram with the train B's plan diagram 481.

  As mentioned above, according to this embodiment and an Example, it is proposed that the number of delays can be reduced by making the number line change target train enter the platform of the change destination candidate and changing the number line by the operation arrangement support system. As a result, when a train traveling delay occurs, it is possible to organize the operation for delay recovery by changing the line to the same platform. In addition, it is possible to realize more efficient train travel by automatically proposing operation arrangement by changing the number of lines.
