Description

  The present invention relates to a driving arrangement support system, and more particularly, to a driving arrangement support system that executes automatic arrangement plan generation for recovering operation disturbance in driving arrangement work.

  When the train operation is disrupted due to bad weather or vehicle failure, the operation management work to restore the operation plan is not only the judgment of the physical conditions such as the train traveling speed and evacuation equipment at the station, but also the vehicle and crew Because it is a multi-purpose, very complex planning work that requires a comprehensive judgment, such as the operation rate of passengers and passenger services, to reduce the burden on the commander who manages the work, and to promote the advancement of skills Techniques related to automation of driving arrangements have been developed.

  As one of the methods for automating driving arrangements, a rule-type driving arrangement logic that can be expressed in IF-Then based on the business know-how in the user's head is constructed, and the schedule change is made by assigning rules to disturbance of operation There is a method for automatic execution.

The technique described in Patent Document 1 stores and holds a user's operation history at the time of operation disturbance as a pattern, and uses the pattern when a similar operation disturbance occurs. However, the technique described in Patent Document 1 has the following two problems.
(1) The versatility of the pattern is poor.

The pattern to be stored will be in the form of “change the order of train X if it is delayed at about A station at around 9:00”, but the time, the station where the delay occurred, and the train are fixed. The pattern is not applied to different times in the same diagram, such as “train Y delayed by” or different trains.
(2) It takes time and effort to input by the user to set the pattern.

  To set the pattern, the user has to enter a number of items. For example, there are timetable changes, time, target station, target train, train position, and the like. When the input contents increase, not only the user's input operation takes time, but also the user's intention may not be correctly reflected in the pattern due to erroneous input or input complexity.

  In order to solve the above-described problems, a driving arrangement support system according to the present invention has the following configuration. In other words, a diagram data table that holds three types of diagram data: operation plan, operation prediction, and operation organization, operation organization simulation unit that executes operation organization generation and operation prediction simulation, diagram data, time on the horizontal axis , A diagram diagram display unit for displaying as a set of straight line diagrams in a coordinate system with the vertical axis as the travel position, a straight line type for a straight line on a diagram showing a part of the diagram data, and a processing method for the straight line according to the type In addition to the line link definition table that defines, and the straight line on the diagram that shows a part of the diagram data in addition to the start point and end point coordinates that indicate the line, it is adjacent to the other line at the start type and end point of the line type Creates a sub-set of streaks from a streak-link generator that converts information to streak links and a line group on the diagram to be updated By comparing the line update unit that executes the update of the line links existing in the set and the display on the diagram, and the update before and after the line link set generated by the line update unit In the schedule data calculated by the driving arrangement rule generator and the driving arrangement simulation section that generates IF-THEN format rules with the schedule and execution section of the train indicated by the delay and update target schedule as the schedule change contents for the train On the other hand, when the operation adjustment rule generated by the operation adjustment rule generation unit is applied and there is a train delay that satisfies the conditional clause, the operation adjustment rule that executes the diagram change shown in the execution clause for the corresponding train And an execution unit.

The diagram data table 1210 holds an operation plan diagram 4100 that is diagram data at the time of operation planning for each train, and an operation calculation diagram 4200 that is operation data calculated by the operation organization simulation unit 1120 and diagram data after operation organization. A table 4300 is a diagram showing a table configuration of the operation plan diagram 4100. The operation plan diagram 4100 has one record of data for each station where the train travels, the station 4310, the station name of the traveling station, the arrival time 4320 at the station, the departure time 4330, this station departure order 4340, the use number line 4350 And has records for all stations from the first train to the last train. Record 4370 shows the operation plan when traveling to station A on 01B, indicating that station A arrival time is 15:00, departure time is 15:02, departure order is seventh, use number line is X number line ing. A table 4400 is a diagram showing a table configuration of the operation calculation diagram 4200. The items in the table are the same as those in the operation plan diagram 4300, but the values calculated by the operation arrangement simulation unit 1120 in FIG. 1 are stored in the arrival time 4420, departure time 4430, departure order 4440, and use number line 4450. Record 4480 is the operation calculation result at the time of traveling to B station of 01B, indicating that B station arrival time is 15:35, B station departure is 15:40, departure order is seventh, use number line is Y line ing.
Returning to FIG. 2, the description of the processing flow in the driving arrangement support system will be continued. In step 2200, the user visually recognizes the operation calculation diagram 4200 displayed in the diagram format in step 2100, and whether there is a straight line that needs to be changed in length, start point, and end point coordinates among the straight lines indicating the diagram data. Determine. If it exists, the process proceeds to step 2300. If it does not exist, the process ends. In this embodiment, a straight line set that is displayed as a single line on the diagram and indicates the same train is referred to as a diamond. Further, in the present embodiment, in the diagram shown in FIG. 3, the length of the straight line 3520 and straight line 3620 between the station A, the station B of the diagram showing 01B and 01C is compressed in the horizontal axis direction, that is, B The user decides that a schedule update is necessary to accelerate the arrival at the station, and as shown in the diagram of Fig. 5, the B station arrival time is changed by changing the B station arrival number of 01B from Y line to X line. The schedule will be changed so that the departure order will be advanced earlier than the 01A train. Of the straight lines indicating 01B in FIG. 5, straight lines 5520, 5530, 5540, 5550, and 5560 are updated straight lines, and the lengths of straight lines 3520, 3530, 3540, 3550, and 3560 in 01B shown in FIG. And updated coordinates. In step 2300, a diagram update method is selected. There are two diamond update methods: a free hand method that simulates a free line drawing method with a pen on the paper surface, and a slide method that updates the diamond by sliding the diamond in the horizontal axis direction. If the user selects the freehand method, the process proceeds to step 2400. If the user selects the stripe slide method, the process proceeds to step 2500.

  FIG. 6 is a diagram showing a processing flow of the diagram updating method using the freehand method of the diagram updating unit 1140 shown in FIG. In step 6100, the line that has the earliest running order among the diamonds to be updated, that is, the straight line that has the start point of the straight line on the left side is selected, and the line link generation unit 1130 in FIG. In addition to this, it is converted into a stripe link to which type information defined in the stripe link definition table 1220 and information indicating the adjacency relationship with other straight lines at the start point and the end point of the straight line are added. In this embodiment, 01B is intended for changing from the shape of FIG. 3 to the shape of FIG. 5, and therefore, the straight line 3520 of FIG. 3 of 01B is selected in this step.

  FIG. 7 is a diagram showing a data structure of a stripe link. Line links are data items that indicate the start point coordinates of a straight line, three items of start point station 7110, start point number 7120, start point time 7130, data items that indicate end point coordinates, end point station 7210, end point number line 7220, end item time 7230, Straight line type 7300 indicating the type of straight line defined in the link definition table 1220, as a data item for uniquely identifying the straight line connected to the straight line on the start point side, the previous link start point station 7410 indicating the station name on the start point side of the straight line, The station name on the start point side of the straight line is a data item that uniquely identifies the three items of the previous link end station 7420 indicating the station name on the end point side, the previous link straight line type 7430 indicating the type of line, and the straight line connecting the straight line and the end point side. 3, a rear link start station 7510 indicating the end station name, a rear link end station 7520 indicating the end station name, and a rear link straight line type 7530 indicating the straight line type. In this embodiment, when the straight line selected in step 6100 in FIG. 6 is converted into a streak link, the starting station 7110 is A station, the starting point line 7120 is an invalid value, and the starting point time 7130 is the departure time from station A 15:00. The end station 7210 is the B station, the end line 7220 is an invalid value, the end time 7230 is the B station arrival time 15:35, the straight line type 7300 is between the stations, and the straight line that is the previous link is not displayed in FIG. Because the type that extends in parallel with the vertical axis from the number line to the station at station A is a straight line departing from the station, the previous link start station 7410 is A station, the previous link end station 7420 is A station, and the previous link straight line type Since 7430 is the station departure, the back link straight line is the straight line 3530 in FIG. 3, so the rear link start station 7510 is the B station, the rear link end station 7520 is the A station, and the rear link straight line type 7530 is the station inner wear. .

  FIG. 8 shows the data structure of the streak definition table 1220. 1 record data is stored for each straight line category, type 8100 indicating the category name of the straight line, straight line definition 8200 indicating the definition of the category classification, straight line in the diagram update by the freehand method of the diagram update unit 1140 in FIG. The update 8300 defines the update method and the update end method, the update end 8400, and the data item of the diagram change extraction method 8500 indicating the extraction method of the diagram change contents executed for the updated straight line. The straight line in which the type 8100 shown in the record 8710 is the station's inner line is the straight line parallel to the vertical axis extending from the station to the number line in the station as shown in the straight lines 3430, 3530, 3630 in FIG. 3, the type shown in the record 8720 The straight lines from 8100 to the station are straight lines parallel to the vertical axis extending from the station number lines to the stations as shown by straight lines 3450, 3550 and 3650 in Fig. 3, and the straight line where the type 8100 shown in record 8730 stops. Is a record showing a straight line extending from the arrival time to the departure time on the number line in the station as indicated by straight lines 3440, 3540, 3640 in FIG. It is assumed that the user can arbitrarily add / delete records in the streak definition table 1220.

  Returning to FIG. 6, the description of the processing flow of the diagram update method by the freehand method of the diagram update unit 1140 of FIG. 1 will be continued. In step 6100, the generated streak link is set as the processing target streak link R, and the process proceeds to step 6200. In step 6200, the user determines whether the processing target stripe link R needs to be updated. If it is determined that the update is necessary, the process proceeds to step 6300. If it is determined that the update is not necessary, the process ends. In step 6300, the coordinate position indicated by the input device 1300 is updated in accordance with the operation of the input device 1300 performed by the user in order to update the diagram. In step 6400, the value of the streak link R is updated in accordance with the coordinate position updated in step 6300 and displayed to the user as a straight line on the diagram. In updating the value of the stripe link, the value determined as shown in the update 8300 of the stripe link definition table 1220 shown in FIG. 1 is updated using the coordinate position acquired in step 6300 as an input. In this embodiment, since the type 8100 of the line link to be updated is station-to-station, the line link end time 7230, that is, the arrival time at station B is updated according to the coordinate position acquired in step 6300. The straight line display of the stripe link is performed by drawing a straight line connecting the start point coordinate and the end point coordinate of the stripe link. In the present embodiment, the value of the streak end time 7230 is updated until the straight line 3520 in FIG. 3 is drawn as a straight line similar to the straight line 5520 in FIG. In step 6500, the updated stripe link R is registered in the stripe link set S indicating the set of stripe links updated in this process. In step 6600, the straight line adjacent to the streak link R on the end point side is converted into a streak link and set as a new streak link R. In the present embodiment, the straight line indicating the streak link R is the straight line 3520 in FIG. 3, so that the streak link indicating the straight line 3530 is newly set as a streak link. The above processing is continued until the straight lines 3520, 3530, 3540, 3550, and 3560 in FIG. 3 showing the simulation result of 01B are equal to the straight lines 5520, 5530, 5540, 5550, and 5560 in FIG. End. The line link set S created by this processing is a line link indicating the five straight lines 5520, 5530, 5540, 5550, and 5560 in FIG. 5, that is, a diamond line indicating the traveling route from the departure of the A station of 01B to the arrival of the C station. It becomes.

  FIG. 9 is a diagram showing a processing flow of the diagram update method by the slide method of the diagram update unit 1140 of FIG. In step 9100, the straight line S at the start end and the straight line E at the end of the diamond to be updated are selected. In this embodiment, as in the case of the diagram update by the freehand method shown in FIG. 6, the 01B schedule shown in FIG. 3 is updated to the 01B diagram shown in FIG. 5, so in step 9100, the straight line 3520 of FIG. The start end S and the straight line 3560 are set as the end E. In step 9200, the straight line S at the start, the straight line E at the end, and the diamond between the straight line S and the straight line E are converted into streak links, and registered in the streak link set S indicating the set of streak links updated in this process. . In the present embodiment, the straight lines 3520, 3530, 3540, 3550, 3560 in FIG. 3 are converted into streak links and then registered in the streak link set S. In step 9300, the streak link generated by converting the straight line S at the start end is set as the streak link R. In this processing, the streak indicating the straight line 3520 in FIG. In step 9400, the user determines whether the processing target stripe link R needs to be updated. If it is determined that updating is necessary, the process proceeds to step 9500, and if it is determined that updating is not necessary, the process ends. In step 9500, the coordinate position indicated by the input device 1300 is updated in accordance with the operation of the input device 1300 performed by the user in order to update the diagram. In step 9600, the line link is updated so that the coordinate position in the horizontal axis direction updated in step 9500 becomes the end point time 7230 of the line link R. In step 9700, the difference X between the end point time 7230 of the stripe link R updated in step 9600 and the end point time 7230 before update is acquired. In this embodiment, since the straight line 3520 in FIG. 3 is changed to the straight line 5520 in FIG. 5, the difference X is about 25 minutes. In step 9800, the value of the start point time 7130 and the end point time 7230 is updated by the difference X for all the streak links in the streak set S except for the streak link R, that is, the start time and the end point time of the streak in the streak link set S. Is updated by sliding X minutes, and the update result is displayed as a set of straight lines on the diagram. If the user determines that no further updates are necessary by looking at the diagram of the update results, the process ends. The stripe link set S created by this processing is a stripe link showing the five straight lines 5520, 5530, 5540, 5550, and 5560 in FIG. 5, as in the case of the diagram update by the freehand method shown in FIG.

  Returning to FIG. 2, the description of the processing flow in the driving arrangement support system will be continued. In step 2600, an operation adjustment rule is generated from the line link set indicating the diagrams that are the targets of the schedule update in steps 2400 and 2500, and registered in the operation adjustment table 1230.

  FIG. 10 is a diagram showing a table configuration of the driving arrangement rule table 1230. The driving arrangement rule table 1230 holds data items of a rule ID 10100 for uniquely specifying the driving arrangement rule and a rule content 10200 indicating the contents of the driving arrangement rule. Each record of the rule content 10200 has a one-to-one correspondence with the line link in the line link set that is the object of the line update by the line update unit 1140 in FIG. A table 10300 is a diagram showing a table configuration of the rule contents 10200. As a data item for uniquely identifying the streak indicated by the record, the streak start station 10310 indicating the name of the streak start station, the streak end station 10320 indicating the end of the streak, and the straight line type of the streak 3 items of line link type 10330 indicating The operation delay 103400 compares the line links updated by the diagram update unit 1140 before and after the update, and indicates the delay amount of the pre-update line link with respect to the line link after the update. If the delay amount is information that can calculate the delay amount from the coordinate position of the two straight lines to be compared, such as the ratio of the length of the straight line indicated by the stripe link in the horizontal axis direction, the difference in length, etc. Good. Moreover, ON / OFF which shows whether it exceeds the threshold value previously designated by the user may be sufficient. A diagram change content 10350 indicates a diagram change content extracted from the stripe links before and after the update. The diagram change content 10350 is extracted by the method defined in the diagram change extraction method 8500 of the stripe link definition table 1220 of FIG.

  FIG. 11 is a diagram showing a flow of processing of the driving arrangement rule generation unit 1150. In step 11100, the operation update rule is generated from the line link set S that is updated by the diagram update unit 1140 of FIG. The driving arrangement rule generated in this step is a generation process rule in which the rule content 10200 has a record group corresponding to all the stripe links included in the stripe link set S on a one-to-one basis. In step 11200, a stripe link set S 'indicating the state before the update of the stripe link set S is acquired. In the present embodiment, the stripe link set S is a set of stripe links showing the five straight lines 5520, 5530, 5540, 5550, and 5560 in FIG. 5, and the stripe link set S ′ is the five straight lines 3520, 3530, FIG. This is a set of streak links indicating 3540, 3550, and 3560. Step 11300 sets the streak link that has the first driving rank in the streak link set S, that is, the earliest start time 7130 as the processing target streak link R. In step 11400, the streak link R and the start station 7110, the straight line definition 7300, The line link having the same end station 7210 is acquired from the line link set S ′ and set to the line link R ′. In this embodiment, the stripe link R is a stripe link indicating the straight line 5520 in FIG. 5, and the stripe link R ′ is a stripe link indicating the straight line 3520 in FIG. In Step 11500, the line link R and the line link R 'are compared, and the operation delay rule operation delay 10340 and the diagram change content 10350 are set for the record in the rule content 10300 indicating the line link R. In this example, the start time 7130 of the line link R is 15:02, the end time 7230 is 15:12, the start time 7130 of the line link R 'is 15:02, and the end time 7230 is 15:35. The delay 10340 takes a value such as a difference in length in the horizontal axis direction = sujilink R′−sujilink R = 23 minutes. In this embodiment, since the threshold value of the difference in length in the horizontal axis direction is 15 minutes, the set value of the operation delay 10340 in this example is ON. The diamond change content 10350 compares the stripe link R and the stripe link R ', and extracts the diamond change content based on the stripe link definition table 1220 of FIG. In step 11600, it is determined whether or not a streaking next to the streak link R, that is, a streak link N indicating a straight line connecting the streak link R and the end point side exists in the streak set S. The process proceeds to step 11800, and if it does not exist, the process proceeds to step 11800, the generated operation arrangement rule is registered in the operation arrangement rule table 1230 in FIG. 1, and the operation arrangement rule generation process ends. In step 11700, the streak link N is newly set to streak link R, and the process proceeds to step 11100. The operation arrangement rule generated in the present embodiment is as shown in FIG. 10, the delay state 10340 is set to “ON” for the stripe link indicating the straight line 5520, and the diagram change content 10350 is indicated for the stripe link indicating the straight line 5530. Is set to `` Change line '', and the line change content 10350 is set to `` Change order '' to the streak indicating the straight line 5540, `` If there is a delay of 15 minutes or more between stations A and B (slow down between stations) This is a rule that means "Change the order and change the line at station B".

  Returning to FIG. 2, the description of the processing flow in the driving arrangement support system will be continued. In step 2700, the operation arrangement rule stored in the operation arrangement rule table 1230 is applied to the operation calculation diagram 4200 stored in the diagram data table 1210 by the operation arrangement rule execution unit 1160 of FIG. The diagram change shown in the execution unit is executed for the diagram showing the operation delay to be satisfied. FIG. 12 is a diagram showing the flow of processing of the driving arrangement rule execution unit 1160. In step 12100, from the operation calculation diagram 4200 of the diagram data table 1210, one piece of train information for which the operation arrangement rule execution determination has not been performed is acquired and set as the processing target train X. In step 12200, it is determined whether or not the train X exists, and if it exists, the process proceeds to step 12300. If the train X does not exist, that is, the operation adjustment rule execution determination is performed for all trains of the operation calculation diagram 4200. If so, the process ends. In step 12300, the diagram from the first train to the last train X is converted into a strip link set T. In step 12400, it is determined whether or not the set T includes the set S in the line link set S indicated by the driving arrangement rule and the line link set T indicating the schedule of the train X. When all the records of the rule contents 10300 of the operation arrangement rule have strealinks uniquely identified by the strealink start station 10310, the streak end station 10320, and the streak line type 10330 in the streak link set T , Suppose set T contains set S. In the present embodiment, when the three trains 01A, 01B, 01C shown in the diagram of FIG. 3 are each train X, the three lines indicated by all the records of the rule content 10300 are displayed. Since it is held in the stripe link set T, it is determined in step 12400 that the stripe link set T includes the stripe link set S. In step 12500, the process branches depending on whether or not the stripe link set T includes the stripe link set S. If the stripe link set T includes the stripe link set S, the process proceeds to step 12600. Returns to step 12100. In step 12600, it is determined whether or not the operation delay 10340 indicated by the driving arrangement rule exists in the stripe link set T. In the rule content 10300, the existence delay of the operation delay is determined by the same operation delay as the operation delay set in the operation delay 10340 in the line link T in the line set T corresponding to the record in which the operation delay 10340 is set. If it has occurred, it is determined that there is an operation delay. The calculation of the delay amount in the stripe links in the stripe link set T is performed based on the value of the operation plan diagram 4100. In this example, the operation delay of the driving arrangement rule is set so that there is a delay of 15 minutes or more in the streak indicating the distance between stations A and B. In 01A of Fig. 3, between AB stations Because there is no delay in the operation, it is determined that there is no operation delay, 01B and 01C have a delay of 15 minutes or more between AB stations, that is, compared to the straight line indicating between AB stations in the operation plan diagram 4100, Since the straight line indicating the distance between the AB stations in the operation calculation diagram 4200 extends in the horizontal axis direction for 15 minutes or more, it is determined that there is an operation delay. In step 12700, the process branches depending on whether or not there is an operation delay corresponding to the operation control rule. If there is an operation delay, the process proceeds to step 12800, and if there is no operation delay, the process proceeds to step 12100. To return. In Step 12800, a schedule change corresponding to the schedule change content 10350 of the operation arrangement rule is executed for the train X. In the case of the present embodiment, the line number change and the order change are performed at the B station for the 01B and 01C lines in FIG. In step 12900, a driving arrangement simulation reflecting the diagram change executed in step 12800 is executed by the driving arrangement simulation unit 1120, and the operation calculation diagram 4200 is updated. FIG. 13 is a diagram showing an operation calculation diagram 4200 in which the schedule change by the operation arrangement rule execution unit 1160 is executed on the 01B and 01C levels in FIG. 3 and the arrival time and the departure time are updated by the operation arrangement simulation unit 1120. is there. In both trains, the arrival time at station B is advanced by changing the number of trains at station B from line Y to line X, and the departure time is advanced by raising the departure order from 01A.

  Returning to FIG. 2, the description of the processing flow in the driving arrangement support system will be continued. In step 2100, the diagram diagram display unit 1110 shown in FIG. 1 displays a diagram as plane coordinates where the vertical axis and the horizontal axis intersect perpendicularly. In addition, the diagram display unit 1110 can be modified as follows. In step 2100, the diagram set display unit 1110 shown in FIG. 1 sets a two-dimensional coordinate system of a diagram showing a plane coordinate in which the vertical axis and the horizontal axis perpendicularly set with the viewpoint as the vertical direction are set by the user. The operation calculation diagram 4200 and the operation plan diagram 4100 generated in Step 2700 are converted into a three-dimensional coordinate system corresponding to the viewpoint position, and are displayed as a diagram in the converted coordinate system.

  FIG. 14 is a diagram showing a diagram after coordinate conversion when the viewpoint position is changed from a directly upward direction to an obliquely upward direction. This diagram is a diagram with the point of view of the diagram of FIG. 13 as viewed from obliquely above. A diagram 13010 is a diagram showing a diagram of 01B in FIG. 13, and shows a wide range of travel paths of 01B. The coordinate conversion calculation from the plane coordinate in which the vertical axis and the horizontal axis are perpendicular to the three-dimensional coordinate system corresponding to the viewpoint position is executed using a known technique applied in a car navigation system or a three-dimensional game.

  As described above, according to the embodiment of the present invention, it is possible to shorten the time required from the acquisition of business know-how in the user's head to the construction of operation arrangement logic incorporating the know-how. In addition, by switching the diagram view from an upward direction to a diagonally upward view like a bird's-eye view, a general-purpose diagram view that overlooks the entire diagram and an enlarged display of key points on the diagram you want to focus on It is possible to display on the same screen without any sense of incongruity, and work efficiency can be improved.
