Description

  The present invention relates to a technology for predicting a future schedule in train operation management.

  The operation management system is a system that automatically controls traffic lights and switchboards based on a train operation diagram. The train operation management system is capable of displaying a display control screen for displaying the position of the train line and controlling troubles for the ground facilities and the course of the train, and an operation organizing screen for changing the diagram and the schedule for the train operation diagram. . The commander who manages the operation of the train confirms the current operation status based on the train line status displayed on the display control screen of the operation management system and the diagram displayed on the operation arrangement screen.

  In recent years, an operation management system having a function of displaying a predicted streak depicting a future driving situation has been developed. The prediction stripe is a drawing of an prediction diagram calculated by the diamond prediction function. The schedule prediction function calculates the estimated time of arrival and departure of the next station, taking into consideration the train schedule, the latest train operation information, and the travel time between stations. This is a function for calculating the expected time diagram by obtaining the arrival and departure times of each station by sequentially performing the process of obtaining the expected arrival and departure times of the next station up to the terminal station. The travel time information between stations is information on the time required for the train to travel between stations, the track circuit travel time, which is the time required for the train to travel between track circuits, and the status of the railway and facilities. And created based on. For this reason, the forecast schedule changes from moment to moment depending on the situation of the railway and facilities. The commander looks at the expected streaks depicting the expected diagram and confirms the future driving situation that changes from moment to moment.

  In addition, when the train is delayed due to various factors such as natural disasters, vehicle breakdowns, bad weather, etc., the commander changes the train operation schedule called operation arrangement in order to recover the train delay. For example, a variety of controls such as changing the train departure order, changing the number of lines used by the train, setting a new train, and stopping the operation of the train are combined to recover the diagram disturbance.

  However, the train schedule is complex, and changes made to recover the delay of a specific train may cause an increase in delay when considered for the entire schedule. Therefore, it is necessary for the commander to determine and take appropriate measures in consideration of the influence of the diamond change on the entire diamond.

  The train operation management system disclosed in Patent Document 1 is based on the above-described diagram prediction function. Before actually changing the diagram, the train operation diagram, the train operation results, the latest station status, and the diagram change to be performed Based on the above, by displaying the predicted streak that predicted the future driving situation, it is possible to assist the commander in determining the schedule change. The commander can change the diagram after confirming the effect on the entire diagram.

  In addition, in the event of a ground facility failure, maintenance inspection, or natural disaster, the commander gives instructions to stop the use of traffic lights, switchboards, and number lines, or limits the speed of train travel for a certain section, from the viewpoint of safe operation of the train. Do. Furthermore, the commander may implement the suppression not only for the train but also for each station in order to adjust the operation interval of the train. The train operation control referred to as trouble control is indispensable because it relates to the safety of train operation, but on the other hand, it is a control that causes a delay in the train by stopping the equipment, prohibiting use of the line, limiting the speed, and the like. For this reason, the commander decides whether to perform the trouble control based on comprehensive judgment in consideration of not only the necessity and urgency of the control but also the degree of influence of the control on the entire diagram.

JP 2011-016461 A

  Currently, it is not considered to calculate a prediction diagram of what will happen when train operation control such as future speed limits is implemented in the operation management system. The above-mentioned trouble control for facilities and sections is actually set for the control, the set control is reflected in the interlocking device, and the operation management system receives state information such as station state information from the interlocking device. It is reflected in. Therefore, it is not possible to confirm the expected diagram when the trouble control is applied before the trouble control is performed. Therefore, it is necessary for the commander to appropriately determine the control to be performed by assuming the influence of trouble control on the entire diagram based on past experience.

  However, since trouble control is a control for parts that affect the operation of multiple trains, such as equipment and sections, the effect is more complicated than the change of the schedule applied to the train operation schedule, and it can be determined whether it is appropriate or not. difficult. At present, the actual situation is that the assessment of impacts often depends on the work experience and know-how of each commander.

  In addition, when trouble control is actually set in the operation management system, there is a problem that a predicted schedule after that may deviate from a subsequent actual train operation, and a predicted streak far from reality may be displayed.

For example, if the speed limit for a certain section at a certain time is input to the operation management system, all the predicted schedules after that are calculated based on the limited speed, and an expected streak is displayed that keeps the speed limit set all the time. The Actually, the expected speed streak will continue even though the set speed limit is continued even though the set speed limit is canceled and the train operation control is expected to change due to subsequent changes in the situation. The fact that it is displayed is not very convenient.
A specific example is shown.

  In the event of a natural disaster such as an earthquake, stop driving is set for an arbitrary section, and in that state maintenance personnel patrol and inspect the tracks and ground facilities. If safety can be confirmed by inspection, the travel stop is canceled and the train travel is resumed.

  However, since the expected time diagram is calculated based on the latest station status information received from the interlocking device, the expected streak appears as if the setting for stopping the travel continues while the travel stop is set. Will be. That is, regardless of whether or not the cancellation of the travel cancellation is expected, the section is stopped in all the prediction schedules of the day, so that a difference occurs between the actual operation and the display of the predicted stripe.

  In addition, when a natural disaster such as heavy rain or strong wind occurs, the speed at which the train travels may be limited. Also in this case, while the speed limit is set, an expected streak is displayed as if the speed limit continues to be set thereafter.

  However, the speed limit is actually released when the weather recovers, and the speed limit is strengthened when the weather gets worse. In other words, in reality, there are more cases where the setting of the speed limit being released or strengthened is changed than when the same speed limit is continuously set. Even in this case, the display of the predicted streak while the speed limit is set deviates from the actual future operation.

  An object of the present invention is to provide a technique that makes it possible to calculate a prediction diagram of what will happen when future train operation control is set in train operation management.

  A diagram prediction apparatus according to an aspect of the present invention is based on a simulation information creation unit that creates simulation information including information on train operation control to be set or canceled at a future time based on an input from a commander, and the simulation information The inter-station travel time creation unit that creates the travel time information between stations according to time zones representing the time required for the train to travel from a predetermined station to the next station for each time zone, and between the stations by time zone A schedule prediction unit for creating a prediction diagram representing a transition of the train position with the passage of time in the future based on the travel time information.

  Hereinafter, the operation of the operation management system will be described focusing on the driving arrangement support device 5.

  First, the general operation of the operation management system will be described.

  In the driving arrangement support device 5, the simulation table creation unit 51 creates simulation information including information on train operation control to be set, changed, or canceled at a future time based on the input of the commander, and the simulation table 56b is used as data. Record in the storage unit 56. The time-to-station travel time creation unit 52 represents the time required for the train to travel from a predetermined station to the next station for each time zone based on the simulation information in the simulation table 56b. The travel time information 56 a is created and recorded in the data storage unit 56. The diamond forecasting unit 53 creates a forecasting diagram representing a transition of the train position with the passage of time in the future based on the traveling time information 56a between stations in the data storage unit 56 and stores the forecasting diagram in the diagram storage unit 57. Record as file 57b.

  According to the present embodiment, since the predicted timetable for the future is created based on the traveling time information 56a according to the time zone calculated from the information of the train operation control assumed at the future time, the train is actually used in the train operation management. Even if the operation control is not set, it is possible to know in advance a prediction diagram indicating what the train operation will be when the future train operation control is set.

  In addition, the traveling time information 56a between stations by time zone trains at least the time zone in which the start time is defined, the inter-station portion represented by two stations included in the route, and the inter-station portion in the time zone. This is information that associates the time required for traveling between stations, which is the time required for traveling. If the simulation information indicates that a predetermined train operation control is set at an arbitrary set time, the time-to-station travel time / minute creation unit 52 determines the speed limit for train travel based on the train operation control. Based on the speed limit, the travel time between stations is calculated, and the time zone after the set time, the inter-station part included in the target of train operation control, and the travel time between stations by time zone are associated with each other. In addition, it is registered in the traveling time information 56a between stations according to time zones. Based on the travel time information 56a between stations by time zone, the diamond prediction unit 53 determines the train position for each time so that the travel time between the stations is required for the train to travel between the stations during the time zone. Create a forecast diagram that defines According to this, the time zone, the inter-station part, and the traveling time between stations are associated with each other in consideration of the speed limit, and the prediction diagram is created using the association information, and therefore changes depending on the speed limit. A prediction diagram that appropriately reflects the position of the train can be created.

  In addition, the train operation control included in the simulation information is a speed limit. In the simulation information, the target part on the route to which the speed limit is applied, the set time for setting the speed limit, the release time for canceling the setting, and the speed A speed limit that is the maximum speed allowed in the limit may be determined. The travel time between stations by time zone refers to the simulation information, and the time from the set time to the release time is the travel time between stations by time zone under the condition that the train travels below the speed limit on the target part. Information 56a is generated. ⇒According to this, when the speed limit is set on a certain part of the route in a certain time zone, the train travel considering the setting and release of the speed limit is reflected in the travel time information 56a between stations by time zone As a result, it is possible to create an appropriate prediction diagram using the appropriate time for traveling between stations according to time zones.

  In addition, the simulation table creation unit 51 registers the simulation information created in advance in the data storage unit 56. The station state information storage processing unit 58 stores, in the data storage unit 56, state information relating to the state of the equipment given in real time as station equipment state information 56d. If the train operation control state based on the station facility state information 56d and the train operation control state based on the simulation information do not match, the simulation table creation unit 51 causes the alarm output unit 55 to output an alarm. According to this, it is possible to notify the discrepancy between the train operation state and the simulated state by an alarm and give the commander an opportunity to determine whether or not to set the train operation control, thus preventing human error etc. Thus, it is possible to apply appropriate control.

  Moreover, the alarm output unit 55 prompts the commander to determine whether to use the actual station equipment state information 56d or to use simulation information (simulation table 56b) on which simulation is performed. For example, a screen for passing selection may be displayed. When it is selected that the simulation information is selected, the simulation table creation unit 51 sets or cancels the train operation control based on the simulation information. Thus, if the commander adopts the simulation information, train operation control based on the simulation information is applied, so the commander does not need to perform an operation to set or cancel the train operation control again.

  In addition, when it is selected that the simulation information is selected, the simulation table creation unit 51 prompts the commander to determine whether or not to set or cancel the train operation control included in the simulation information. The train operation control may be set or canceled. If the commander adopts simulation information and determines that the train operation control is necessary, the train operation control is applied, so the commander needs to perform an operation to set or cancel the train operation control again. It can be carried out with no confirmation.

  When the alarm output unit 55 prompts the commander to adopt the station facility state information 56d or the simulation information, when the commander selects the station facility state information 56d, the simulation table creation unit 51 The simulation information in the simulation table 56b may be discarded. In this case, if the commander adopts the station equipment state information, the simulation information is discarded, so that the commander does not need to perform an operation to discard the simulation information again.

  The simulation table creation unit 51 has a predetermined relationship with the set time or release time of train operation control in the simulation information registered in the simulation table 56b of the data storage unit 56, and the station equipment state information If the train operation control state based on the information and the train operation control state based on the simulation information do not match, the alarm output unit 55 is made to output an alarm. The predetermined relationship described above may be, for example, a case where the current time has become the set time, a current time is between the set time and the release time, a current time is a predetermined time before the set time, or various embodiments. Can be considered. When the current time has a predetermined relationship with the set time or cancellation time, if there is a discrepancy between the train operation state and the simulated state, should this be notified by an alarm, and whether train operation control should be set for the commander? Since an opportunity to determine whether or not can be given, it is possible to prevent human error or the like and apply appropriate control.

  The simulation table creation unit 51 registers the simulation information created in advance in the data storage unit 56, and the current time is a predetermined time before the set time or release time of the train operation control in the simulation information registered in the data storage unit 56. The alarm output unit 55 may output an alarm. It is possible to notify the operator that the time when the train operation control is set or canceled in the simulation is approaching, and to give the commander the opportunity to determine whether or not to set the train operation control, thus preventing human error etc. Thus, it is possible to apply appropriate control.

  In addition, the display processing unit 54 performs processing for displaying a diagram of a predicted diagram created by the diagram predicting unit 53 on the screen. Since the commander can check the schedule of the expected schedule based on the simulation information on the screen display, train operation will not be performed if the train operation control is set in the future, even if the train operation control is not actually set in the train operation management. You can visually check what happens.

  Hereinafter, the operation of the operation management system will be described more specifically.

  The process of each device when creating a prediction diagram reflecting simulation information will be described.

  FIG. 3 is a diagram showing an example of the simulation information input screen. FIG. 3 shows a simulation information input screen for inputting simulation information from the display control screen. FIG. 4 is a diagram showing another example of the simulation information input screen. FIG. 4 shows a simulation information input screen for inputting simulation information from the operation arrangement screen.

  If FIG. 3 is referred, each station and a track will be drawn on the display control screen, and it will be displayed on the track where the train exists. The commander displays the simulation input screen 21a, inputs the restricted equipment / section, the restricted time, the restricted speed, and the restricted content, and presses the “set” button. Restricted equipment / sections can be set by clicking on the target equipment or section on the screen or by entering the equipment / section name. The time limit can be set by inputting the time. The speed limit can be set by inputting the speed. For example, when the facility is stopped, 0 km / h may be input as the speed limit. The restriction content can be set by inputting the restriction content. In the example of FIG. 3, the content is set to prohibit the use of the downlink No. 1 in the time zone from 15:00 to 16:30.

  Referring to FIG. 4, on the operation arrangement screen, the vertical axis indicates the station where the train travels, the horizontal axis indicates the time, and the schedule of the train schedule such as the past actual schedule and the future expected schedule is displayed. . The commander displays the simulation input screen 31a, inputs the restricted equipment / section, the time limit, and the speed limit, and presses the “SET” button. Restricted equipment / sections can be set by clicking on the target equipment or section on the screen or by entering the equipment / section name. The time limit can be set by clicking the start time and end time on the screen or by inputting the time. The speed limit can be set by inputting the speed. When the facility is stopped, 0 km / h may be input as the speed limit. The restriction content can be set by inputting the restriction content. In the example of FIG. 4, a speed limit of 30 km / h is set in a time zone from 13:00 to 13:50 in a section between 191.2 km and 199.2 km on the downlink.

  When the commander inputs train operation control from the simulation information input screen of FIG. 3 or FIG. 4, the simulation table creation unit 51 registers the train operation control information in the simulation table 56 b of the data storage unit 56.

  The simulation information is information specifying train operation control for performing simulation. If it is a simulation of train operation control that limits the speed to a certain section, the limited section indicating the section to be limited, the limited time that is the time to apply the limit, the limited speed that is the maximum allowable speed, and the speed limit Each piece of information on the restriction content indicating that the item is to be applied is included.

  The simulation table 56b is a table in which simulation information is registered. FIG. 5 is a diagram showing the simulation table 56b of the present embodiment. When the simulation information is input by the commander, each information of the restriction section, the restriction time, the restriction speed, and the restriction content is stored in the simulation table 56b in association with each other.

  The simulation table creation unit 51 registers simulation information in the simulation table 56b.

  FIG. 6 is a diagram showing an example of the simulation information deletion screen. FIG. 6 shows a simulation information deletion screen for deleting simulation information from the operation arrangement screen.

  Referring to FIG. 6, the commander displays the simulation data deletion screen 31b, selects the simulation information to be deleted from the simulation information stored in the simulation table, and presses the “set” button to execute the simulation. Information can be deleted.

  When the commander deletes the train operation control simulation information from the simulation information deletion screen of FIG. 6, the simulation table creation unit 51 deletes the train operation control information from the simulation table 56 b of the data storage unit 56.

  Further, the commander may be able to input to change the setting contents of the train operation control in the simulation information. In that case, when the commander inputs that the train operation control is changed from the simulation information input screen of FIG. 3 or FIG. 4, the simulation table creation unit 51 uses the simulation of the data storage unit 56 to change the train operation control information. Register in the table 56b.

  After the simulation table 56b is created, the inter-station travel time / minute creation unit 52 creates the inter-station travel time / minute information 56a defining the travel time between stations for each time zone. FIG. 7 is a diagram showing the traveling time information 56a between stations according to time zones in the present embodiment. The time-to-station travel time / minute information 56a stores information relating to time zones, between stations, passage time, stop time, stop time, and stop time in association with each other.

  An example of the time required for the train to travel between A station and B station will be described. A running time is defined for each of the upward direction and the downward direction. The running time includes a passing time, a stopping time, a stopping time, and a stopping time. In the direction from the A station to the B station, the passage time is the running time when the A station is a passing station and the B station is a passing station. The stop time is the running time when station A is a passing station and station B is a stop station. The stop time is the running time when station A is a stop station and station B is a passing station. The stop time is the travel time when station A is a stop station and station B is a stop station. A combination of information for each time zone, between stations, at the time of passage, at the time of stoppage, at the time of stoppage, and at the time of stoppage is defined for each station and above and below in one table. For example, if both the A station and the B station are passing stations in the upward direction between the A station and the B station, the running time (communication time) is X1a seconds. Then, a table is created for each such time zone for each time zone.

  Next, the diamond prediction unit 53 makes a diamond prediction by referring to the operation plan file 57a and the operation result file 57c of the diagram storage unit 57 and the travel time information 56a according to the time zone of the data storage unit 56, and the generated prediction The diamond is stored in the expected diamond file 57b of the diamond storage unit 57.

  The display processing unit 54 acquires the predicted diagram file 57b of the diagram storage unit 57 and transmits it to the predicted line display unit 42. The predicted diagram display unit 42 draws the predicted line on the operation arrangement screen. As a result, the commander can see the expected streak reflecting the simulation information on the screen.

  FIG. 8 is a diagram illustrating an expected streak before the simulation information is input. FIG. 9 is a diagram illustrating an expected streak after the simulation information is input. By the above processing, the predicted streak before the simulation information input shown in FIG. 8 becomes the predicted streak after the simulation information input shown in FIG. 9 by inputting the simulation information shown in FIG. It is possible to grasp the influence of train operation control such as trouble control in simulation information on the entire operation schedule before setting the control.

  When the simulation information is input in FIG. 4 and “setting” is pressed, the speed limit set in FIG. 4 is applied as shown in FIG. The predicted streak (31c, 31d) in which the speed is lowered, that is, the inclination is reduced is displayed. In the example of FIG. 9, when displaying the predicted streaks, the predicted streaks included in the restricted facilities / sections and time limits are displayed with thick lines or colors so that the commander can clearly recognize the location where the delay is caused by the simulation information. It is changed and displayed. Furthermore, a screen 31e that allows the user to check the contents of the simulation information by popping up the screen by selecting an expected stripe based on the simulation information on the screen is displayed.

  In addition, the simulation table creation unit 51 determines whether or not the simulation data and the station equipment state information match at an arbitrary cycle. If they do not match, the simulation table creation unit 51 activates the alarm output unit 55 to output an alarm. The alarm output unit 55 outputs an alarm for notifying the commander that the simulation information and the station equipment state information are inconsistent, and which of the simulation information and the station equipment state information should be adopted and reflected in the prediction diagram Display the screen to ask the commander about selection.

  When the instructor selects the station equipment state information, the simulation table creation unit 51 discards the simulation information, and the hourly travel time between stations creation unit 52 obtains the travel time information between stations by time zone. The schedule prediction unit 53 re-creates the schedule diagram based on the station equipment state information. On the other hand, when the commander adopts the simulation information, the diagram predicting unit 53 creates a prediction diagram based on the simulation information.

  FIG. 10 is a screen showing an alarm that is output when the simulation information and the current station equipment state information do not match, and an inquiry for selecting a method for creating a predicted diagram in that case. FIG. 11 is a diagram showing an expected streak displayed when the commander selects the station equipment state information when an alarm is output.

  Referring to FIG. 10, an alarm is output because the simulation data and the latest station state information do not match. In addition, a display prompting the commander to select information used for the diamond prediction is displayed. When the simulation data and the station state information do not match, the commander is notified by the alarm sound and the alarm screen 31h that the simulation information and the station state information do not match. On this alarm screen 31h, it is possible for the commander to select whether to perform a diamond prediction based on simulation data or station state information.

  Referring to FIG. 11, there is shown an expected streak displayed when the commander selects station equipment state information at the time of alarm output in FIG. When the “Yes” button is pressed in FIG. 10, an expected line of an expected diagram based on station equipment state information is displayed. The example of FIG. 11 is a display of the predicted streak in the state where trouble control is not set at the current time. Since train operation control by simulation information is not included, there is no train line of thick line.

  As a result of the above processing, when an alarm is displayed on the screen as shown in FIG. 10, when the commander selects the station equipment state information, an expected streak based on the station equipment state information is displayed as shown in FIG. Further, when the simulation information is selected, it is possible to display an expected line based on the simulation information.

  Further, the alarm output unit 55 has a function of proposing to execute train operation control based on the simulation information when the commander selects the simulation information. And when a commander accepts a proposal and chooses to carry out train operation control, alarm output part 55 transmits execution instruction of train operation control to interlocking device 9 shown in FIG.

  FIG. 12 is a diagram illustrating a screen that prompts selection of whether or not to perform train operation control based on simulation information when the commander selects simulation information in response to an alarm. FIG. 13 is a diagram illustrating an expected line displayed when the train operation control based on the simulation information is selected. FIG. 14 is a diagram illustrating an expected streak displayed when the train operation control is not selected based on the simulation information.

  Referring to FIG. 12, when an alarm is output as shown in FIG. 10, a display of an expected line when the commander selects the simulation information is shown. When the “No” button is pressed by the instructor in FIG. 10, the station equipment state information and the simulation information do not match, so as shown in FIG. 12, it is selected whether to perform control based on the simulation information. An inquiry screen 31i is displayed. Here, when the commander presses the “control” button, the control based on the simulation information is actually performed.

  Referring to FIG. 13, a display of an expected line after the “control” button of FIG. 12 is pressed is shown. Expected stripes using simulation information from the current time are displayed. As described above, the trouble control based on the simulation information is set by pressing the “control” button. Here, since the trouble control is set at the current time, the predicted streak (31j, 31k) on which the speed limit at the current time is applied is displayed.

  Referring to FIG. 14, an expected line after the “Cancel” button in FIG. 12 is pressed is displayed. The simulation information at the current time or immediately after it has been canceled, but at the future time, an expected streak employing the simulation information is displayed. Since the trouble control is not set at the current time, the predicted line (31l) at the current time is not speed-limited, and the predicted line (31m) at the future time reflects the speed limit. Yes.

  When the commander selects that the train operation control is performed based on the simulation information on the selection screen illustrated in FIG. 12 by the above processing, an expected streak in which the train operation control is performed as illustrated in FIG. 13 is displayed. Is done. On the other hand, when it is selected not to perform the train operation control based on the simulation information, an expected streak in which the train operation control based on the simulation information is not performed is displayed as shown in FIG.

  In addition, the alarm output unit 55 has a function that proposes to set or cancel the train operation control based on the simulation information before an arbitrary start time (set time) or end time (release time) of the restriction in the simulation information. Have. When the commander selects that the train operation control based on the simulation information is to be performed from the screens proposed to reflect the simulation information shown in FIGS. 15 and 16, the alarm output unit 55 An instruction for train operation control is transmitted to the shown interlocking device 9.

  FIG. 15 shows a screen 31f for outputting an alarm for proposing the start of control based on the simulation information any time before the limit start time in the simulation information. When the commander presses the “Yes” button, a control instruction based on the simulation information is transmitted to the interlocking device 9 shown in FIG. 2, and trouble control is set for the field equipment.

  FIG. 16 shows a screen 31g for outputting an alarm for proposing release of control based on the simulation information before an arbitrary time before the limit end time in the simulation information. When the commander presses the “Yes” button, a control instruction based on the simulation information is transmitted to the interlocking device 9, and the trouble control for the field facility is released.

  By looking at the screen that proposes train operation control based on simulation information by the above processing, it is possible to select whether or not to implement train operation control, and to reduce the burden on the commander in setting and canceling simulation information . In addition, since alarms are output at the restriction start time and end time, it is possible to prevent the user from forgetting to set or cancel the control.

  FIG. 17 is a flowchart showing the processing of the simulation table creation unit 51 according to this embodiment. The simulation table creation unit 51 is activated when simulation information is input or deleted by the commander and when train operation control such as trouble control is set or canceled.

  In step 51a, the simulation table creation unit 51 determines whether the given data is input or deletion of simulation information. If the given data is input or deletion of simulation information, in step 51b, the simulation table creation unit 51 registers or deletes the input simulation information in the simulation table.

  If the given data is not the input or deletion of simulation information, in step 51c, the simulation table creation unit 51 determines whether there is simulation information in the simulation table 56b.

  When there is simulation information, in step 51d, the simulation table creation unit 51 determines that the latest station equipment state information is within the time limit in the simulation information, and the equipment state of the station equipment state information is the restricted section of the simulation information. It is determined whether or not it matches with the speed limit and the limit contents. If they match, that is, if the latest station equipment state information matches the simulation information, the simulation table creation unit 51 ends the process.

  If they do not match, the simulation table creation unit 51 activates the alarm output unit 55 in step 51e. When station equipment state information is selected as information used to create a predicted diagram in step 51f (YES), the simulation table creation unit 51 deletes the corresponding simulation information in step 51g. On the other hand, when simulation information is selected (NO), the simulation table creation unit 51 ends the process.

  FIG. 18 is a flowchart showing the processing of the hourly travel time zone creation unit 52 according to the present embodiment. The time-to-station travel hour / minute creation unit 52 is activated at an arbitrary cycle when simulation data is input or deleted by the commander. When the hourly travel time station creation unit 52 is activated, in step 52a, the current time HH: MM is acquired, and the current time is set to hh: mm. After setting HH: MM to hh: mm, the time-to-station travel time creation unit 52 determines whether hh: mm is the current time in step 52b.

  When hh: mm is the current time, the time-to-station travel time / minute creation unit 52 uses the latest station equipment state information and track circuit travel time / minute information in step 52e to travel between stations by time zone. Minute information 56a is created. Track circuit travel time is the time required for the train to travel between track circuits.

  On the other hand, if hh: mm is not the current time in step 52b, the inter-station travel hour / minute creation unit 52 determines whether hh: mm is within the time for which the simulation information limit is set in step 52c. To determine. If hh: mm is not within the time limit is set, the time-to-station travel time / minute creation unit 52 creates time-by-time station travel time / minute information 56a in step 52e.

  On the other hand, if hh: mm is within the time when the restriction is set in step 52b, the inter-station travel time / minute creation unit 52 generates simulation information and track circuit travel time / minute information in step 52d. It uses and creates the traveling time information 56a between stations according to time zone.

  In step 52d or step 52e, after creating the time-to-station travel time / minute information 56a by time zone, the time-to-station travel time / minute creation unit 52 determines the scheduled time at which the last train of the day will finish running in step 52f. It is determined whether or not the traveling time information 56a between stations by time zone has been created up to minutes. When the time-to-station travel time / minute information 56a has not been created until the scheduled time at which the last train finishes traveling, the time-to-station travel time / minute creation unit 52 determines hh: mm in step 52g. Are added, ie, hh: mm = hh: mm + cycle time, and the process returns to step 52b.

In step 52f, when the time-to-station travel time / minute information 56a for the entire time period until the final train finishes traveling has been created, the time-to-station travel time / minute creation unit 52 performs the processing. finish.
