Abstract

PROBLEM TO BE SOLVED: To provide a technique for reproducing a past train operation state in a state that a state during the operation can be easily grasped.SOLUTION: A log management device for using data acquired on an operation management system for displaying a train on-rail state and reproducing the on-rail state comprises: log collection means for accumulating pieces of data which are acquired for actual operation by the operation management system as logs; and reproduction information editing means for creating an on-rail reproduction screen in which the on-rail state which is displayed for actual operation by the operation management system, based on the logs, and reference information which is not displayed for actual operation, are combined.

Description

  The present invention relates to an operation management system for managing the operation of trains, and more particularly to a technique for reproducing the status of train operations using logs collected by the operation management system.

  In train command operations, when the schedule is disrupted due to incidents such as accidents, bad weather, equipment failures, human errors, etc., train operations can be continued by manual route control or operation arrangement by the commander, and the schedule disturbance can be recovered. There are things to do. The operation arrangement is to temporarily change the train operation plan, for example, in order to recover the disturbance of the diagram. Further, here, manual route control and operation arrangement are combined and referred to as manual control.

  Whether or not effective manual control can be performed according to the situation when there is a disturbance of the diamond or the like depends on the experience, skill, command style, etc. of the commander. That is, the optimal recovery procedure cannot always be performed, and a recovery procedure that is not optimal may be performed. Therefore, the contents and results of recovery actions performed in the past can be stored and shared as a log, and the past logs can be used as a reference when similar situations occur so that recovery actions that are as effective as possible can be implemented. There is an attempt to do.

  For example, if the actual incident situation is recorded and played back on the terminal, it may be useful to look back on the action at that time and search for an optimal solution. In addition, by replaying the process leading to an incident, an application may be used to investigate the cause of the incident occurring and to investigate the precautions to avoid it. Furthermore, it can be used for educational purposes such as training inexperienced commanders, such as newcomers, using actual incident response cases.

  Some operation management systems have a function of acquiring a screen capture of the command terminal by the operation of the commander. Mainly, it is required to capture a screen that displays the line status that is constantly updated as the train travels. The playback function is also useful in the scene of capturing the screen in this way. For example, the screen may be updated before the commander performs an operation to acquire a capture, and an intended screen capture may not be acquired. However, by using the playback function, it is possible to play back the status of the current line and acquire the capture so that the intended screen capture is not missed.

  Therefore, in Patent Document 1, the operation management system is provided with an on-line simulator, and the interlocking state and the on-line state of the train at the time specified using the interlocking log and the tracking log are reproduced on the simulator, and based on the diagram from this state A function for executing a simulation has been proposed.

  In addition, in Patent Document 2, in addition to the reproduction function using the standing line log, a function for automatically determining the occurrence of a power failure or failure from the standing line state and recording the time is provided. It has been proposed to support playback.

  In any example of Patent Documents 1 and 2, the train presence state is reproduced on the screen. However, it is not easy to identify the train that is not automatically controlled in relation to the incident and what is the cause of the failure of the automatic control just by looking at the status of such a train. Absent.

  In addition, it is not easy to tell whether a controlled train is controlled automatically by an operation management system or manually controlled by a commander. Furthermore, in the case of manual control, it is difficult to know from which terminal the manual control is performed.

  For example, if the server of the operation management system accumulates logs and can directly acquire and analyze logs from there, it may be possible to know the situation. However, it is troublesome to directly extract logs on the operation management server that are not supposed to be frequently acquired and analyzed. Moreover, the installation location of the operation management server may be away from the location where the commander is usually located. In addition, logs acquired directly from the operation management server, which are not assumed to be frequently analyzed, may require specialized knowledge to perform analysis.

  An object of the present invention is to provide a technique that makes it possible to reproduce the operation state of a past train in such a manner that the situation at the time of operation is easy to understand.

  A log management device according to an aspect of the present invention is a log management device for reproducing the standing line state using data acquired by the operation management system that displays the standing state of a train, and the operation management system includes: Combining log collection means for accumulating data acquired in actual operation as a log, based on the log, the line status displayed by the operation management system in actual operation, and reference information not displayed in the actual operation Reproduction information editing means for creating a standing line reproduction screen.

  According to the present invention, not only the current train status at that time is displayed, but also the status of control that is not displayed on the screen at that time is displayed. It is possible to reproduce the situation of the time so that it can be easily understood.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of an operation management system according to the present embodiment. According to the figure, the operation management system includes a command terminal 1, business servers 2 to 5 that perform processing related to train control, and a log management server 6. The command terminal 1, the business servers 2 to 5 that perform processing related to train control, and the log management server 6 are connected to the network 0 together with field equipment 7 such as traffic lights and switches.

  During the operation of the operation management system, the commander performs command work using the command terminal 1. The command terminal 1 can display an on-line screen representing the on-line state of the train sent from the on-line display server 2 and a diagram screen representing the diagram sent from the operation organizing server 3.

  In addition, in this figure, the apparatus with little relation with each business server 2-5 which performs the process regarding train control, the log management server 6, and the command terminal 1 is abbreviate | omitted.

  In general, the operation management system includes a plurality of command terminals 1. In addition, the business servers 2 to 6 and / or the network 0 may be multiplexed and a redundant configuration may be employed. However, these are also omitted in the figure.

  Further, the system configuration shown in this figure is merely an example, and this configuration is not necessarily required. For example, any business servers 2 to 5 may also serve as the log management server 6. Alternatively, instead of providing a server dedicated to log management, the functions of the log management server 6 may be divided and incorporated into the respective business servers 2 to 5 in a distributed manner. In that case, the business servers 2 to 5 that have received the reproduction request may edit their own logs as necessary and retransmit them directly to the command terminal 1.

  FIG. 2 is a diagram illustrating an example of various logs collected in the present embodiment. This figure shows the correspondence between various log types, devices that output these logs, and devices that collect these logs.

  However, the log that needs to be collected varies depending on what information is displayed when the on-line state is reproduced. Therefore, there are cases where it is not necessary to collect all types of logs exemplified in this figure. Further, the collected logs are not limited to those shown in the figure. Different information may be displayed by changing the collected log.

  During actual operation of the operation management system, the course of the train is automatically controlled by the route control server 5 making a control request to the field facility 7 based on the implementation schedule and the on-line status. Then, the route control server 5 sends the content of the route control to the on-line display server 2 at a constant cycle, and outputs a route control log 11 in which this is recorded. Information such as the train position and delay time of the train is acquired by the route control server 5 and sent from the route control server 5 to the track display server 2.

  Further, during actual operation of the operation management system, the state of the on-site equipment 7 such as the track circuit falling state is sent from the on-site equipment 7 to the on-line display server 2 through the route control server 5 or directly. The standing line display server 2 collects information on the state of the on-site equipment 7, creates drawing information to be displayed on the standing line screen of the command terminal 1, and sends it to the command terminal 1 at a constant cycle. The standing line display server 2 accumulates drawing information as a log, and outputs a standing line drawing information log 12 in which the drawing information is recorded. The command terminal 1 displays a standing line screen based on the drawing information received from the standing line display server 2.

  Normally, the train is automatically controlled by the route control server 5, but the route control server 5 may be suspended without performing automatic control on the train depending on the situation. For example, when there is no train in the approach section defined for each route, when another train has a track or route in the track circuit on the route, the departure (passing) time on the diagram is approaching If not, if the passing order on the train schedule is not first, if the route is a route designated to suspend automatic control until the next route is secured, automatic control is suspended, etc. The Thus, when hold | maintaining automatic control, the course control server 5 records the train, place, and reason which hold automatic control on the course control log 11. FIG.

  In the case where the operation management system has a function of outputting an alarm relating to route control, the on-line display server 2 relates to the event that the alarm has occurred, the content of the alarm, the occurrence time, and the time when the commander responds to the alarm. A control alarm log 14 in which (response time), response contents, etc. are recorded is generated and output.

  The operation organizing server 3 holds information on schedule schedules, implementation schedules, and travel results up to the present, and predicts future operation status from the results. If the operation schedule is implemented, the implementation schedule will reflect the result of the operation arrangement.

  Further, in addition to the plan diagram, the implementation diagram, the actual results, and the prediction, the operation organizing server 3 sends data to be displayed on the diagram screen to the command terminal 1 at regular intervals as drawing base information. The command terminal 1 reconstructs the drawing base information received from the operation control server 3 and displays a diagram screen. The drawing base information may include, for example, irrational information indicating irrationality such that a train competes on prediction. Further, the operation arranging server 3 records the drawing base information as a log, and outputs the recorded diagram drawing base information log 15. The diagram drawing base information log 15 to be recorded and held may be limited to a fixed time including the current time among the drawing base information sent to the command terminal 1.

  The command terminal 1 can manually control the course of the train by a predetermined operation from the standing line screen. The contents of the manual control requested at the command terminal 1 are sent to the field facility 7 through the standing line display server 2. The field facility 7 checks the content of the received control request, and if there is no problem, controls the content.

  When the operation for manually controlling the route is performed at the command terminal 1, the standing line display server 2 records the content of the route control requested from the command terminal 1 as a log and outputs the recorded standing line manual control log 13. .

  Moreover, in the command terminal 1, it is possible to arrange driving | operation by predetermined operation from a diagram screen. The contents of the operation control requested by the command terminal 1 are sent to the diagram management server 4 through the operation control server 3. The diagram management server 4 checks the contents of the received operation arrangement, and if there is no problem, changes the execution schedule by the operation arrangement of the contents.

  When the operation adjustment operation is performed at the command terminal 1, the operation adjustment server 3 records the contents of the operation adjustment requested from the instruction terminal 1 and the check result by the diagram management server 4 as a log. The operated operation log 16 is output.

  In general, an operation management system is provided with a plurality of command terminals 1, and each command terminal 1 is assigned a unique terminal number. When the manual control as described above is performed, the standing line display server 2 and the operation organizing server 3 associate each manual control with the terminal number of the command terminal 1 that executed the manual control, and the standing line manual control log 13, the driving Each of the arrangement log 16 and the control alarm log 14 is recorded including the terminal number of the command terminal 1 that has executed manual control.

  In addition, when the command terminal 1 has a function of specifying a user and permitting login, the login or logout event is associated with user information such as a user ID or a user name at the time of login and logout. It records as a log and outputs the recorded terminal / user information log 17. This makes it possible to specify which command terminal 1 has performed manual control and who has performed manual control.

  Note that each log described above is output for display when the on-line state is reproduced later, and is not used for real-time monitoring in actual operation. For this reason, the various logs generated by the business servers 2 to 5 do not necessarily have to be output in the same cycle as the real-time information corresponding to the logs is transmitted for actual operation. Various logs may be output with a cycle thinned to such an extent that there is no problem in reproduction on the screen and use of the information.

  FIG. 3A is a diagram illustrating an example of a standing line screen that displays a standing line state during actual operation of the operation management system. FIG. 3B is a diagram illustrating an example of a diagram screen that displays a diagram status during actual operation of the operation management system.

  During operation of the operation management system, the command line 1 can display the standing line screen 21 (FIG. 3A) sent from the standing line display server 2 or the diagram screen 22 (FIG. 3B) sent from the operation arrangement server 3.

  Referring to FIG. 3A, in the standing line screen 21, in addition to the current time 210, for example, the track circuit falling state and the route setting state 211, the traffic signal indication 212, the train number 213 in the standing line, the passage rank 214 of a specific location, the train The information such as the delay time 215 and the alarm 216 related to the control are displayed together with the track diagram.

  The track circuit fall state and the route setting state 211 indicate how the track is set by the track circuit. The state of the track circuit is displayed on the track diagram. The track is divided into track circuits, the track circuit on which the train is located is indicated by a thick thick line, and the track circuit set as the course of the train is indicated by a light thick line. The traffic signal indicator 212 indicates the state of the traffic signal. The traffic light indicates whether or not it is possible to proceed by “G” and “R”. In the figure, “G” indicates a green signal and “R” indicates a red signal. The number of train numbers 213 in the current line is displayed on the train parts on the track. A pentagonal block shows the train and its direction of travel, and the numbers in the block show the train number. The passage rank 214 of a specific place is the priority of the train which passes about a specific place, and is displayed on the vicinity at the specific place. For example, it can be understood that the first priority is the train number with which train number. The train delay time 215 is a train delay time and is displayed in the vicinity of the train. The control-related alarm 216 is displayed at the bottom of the screen.

In addition, information for specifying the place and equipment such as the station name 217 and the equipment numbers 218 and 219 such as traffic lights and track circuits may be displayed in the vicinity of the corresponding display component.

  Referring to FIG. 3B, in addition to the current time 210, the schedule screen 223, the actual line 224, and the predicted line 225 are displayed on the diagram screen 22 as a line graph on the two-dimensional coordinates including the time axis 221 and the station name axis 222. ing. In addition, information such as the train number 226 may be displayed near the streak to identify the train.

The plan line 223 indicates the arrival and departure times on the schedule for each train. The actual result line 224 represents the time at which actually arrived and departed from the past time. The prediction line 225 represents the departure / arrival time predicted from the actual results with respect to the future time.

  Note that the types of screens displayed on the command terminal 1 shown individually, the components displayed on each screen, and the display forms of the components are examples, and are not necessarily as shown in the figure.

  4A to 4F are diagrams illustrating an example of a state where a train is not automatically controlled. These are just general examples, and there are actually many other situations that are not automatically controlled. Even if these examples are met, automatic control may be possible depending on other conditions.

  FIG. 4A is a diagram illustrating a first example of a state where a train is not automatically controlled. The route control server 5 may be put on hold without performing automatic control of the traffic lights when the train is not in the approach section determined for each route. In the example of FIG. 4A, the approaching section of the traffic light S413 is the track circuit C412 to 413, but the train 411 is still on the track circuit C411 and has not reached the approaching section. Therefore, automatic control for the traffic light S413 is suspended.

  FIG. 4B is a diagram illustrating a second example of a state where the train is not automatically controlled. The route control server 5 may be suspended without automatically controlling the traffic signal to the route when another train has set a track or route in the track circuit on the route. In the example of FIG. 4B, the train 421 is present on the track circuit C421, but the track circuit C422 ahead is set as the course of the other train 422, so the traffic light S421 is not automatically controlled and is suspended. Yes.

  FIG. 4C is a diagram illustrating a third example of a state where the train is not automatically controlled. If the route control server 5 is not approaching the departure (or passage) time on the diagram, the route control server 5 may hold the signal without automatically controlling it. In the example of FIG. 4C, the train 431 is on the track circuit C431, but the current time is not approaching the departure time 12:20, so the traffic light S431 is not automatically controlled and is suspended.

  FIG. 4D is a diagram illustrating a fourth example of a state where the train is not automatically controlled. The route control server 5 may suspend without automatically controlling the route of a train whose passing order on the diagram is not first. In the example of FIG. 4D, since the passing order of the train 441 in the track circuit C443 is not first, the traffic light S442 on the route of the train 441 is put on hold without being automatically controlled.

  FIG. 4E is a diagram illustrating a fifth example regarding a state where the train is not automatically controlled. The course control server 5 may suspend automatic control for some designated courses until a future course is secured. In the example of FIG. 4E, the route of the traffic light S451 is a route designated to be suspended until the previous route is secured, and since the route of the traffic light S452 is not drawn, the traffic light S451 is not automatically controlled and is suspended. Yes.

  FIG. 4F is a diagram illustrating a sixth example regarding a state where the train is not automatically controlled. The route control server 5 may suspend automatic control for a long train for a part of designated routes until a future route is secured. In the example of FIG. 4F, the route of the traffic light S462 is a route designated to be suspended until the previous route is secured for the long train, and the route of the traffic light S464 is not drawn, so the track circuits C461 and C462 are not drawn. The traffic light S462, which is the route of the long train 461 that is on the line, is put on hold without being automatically controlled.

  5A to 5D are diagrams illustrating an example of manual control (hereinafter referred to as standing line manual control) that can be executed from the standing line screen 21. However, what is illustrated in this drawing is a part of the standing line manual control, and there are other standing line manual controls.

Here, the starting point traffic light S511 and the landing point traffic light S513 are designated to set the course.

  FIG. 5B is a diagram illustrating a second example of standing line manual control. The example of FIG. 5B is an example of canceling the setting of the route for the section from the track circuit C522 to the track circuit C523, which has been set as the route of the train 521 existing in the track circuit C521. Here, the setting of the course is canceled by designating the traffic light S521 as the starting point.

  FIG. 5C is a diagram illustrating a third example of standing line manual control. The example of FIG. 5C is an example in which the train number of the train 531 on the track circuit C531 is changed from 531 to 532.

  FIG. 5D is a diagram illustrating a fourth example of standing line manual control. The example of FIG. 5D is an example of changing the passing order of the train 541 and the train 542 in the track circuit C543. Here, since the passing order of the train 541 is first, the track circuit C543 and the track circuit C544 are set as the course of the train 541 by automatic control to the traffic light S542.

  6A to 6G are diagrams illustrating examples of various logs collected by the log management server 6. In this figure, the log is illustrated in a tabular form, but this does not indicate the actual log format.

The control alarm log 14 illustrated in FIG. 6D is output from the on-line display server 2 when an alarm is output to the on-line screen 21 and when a response to the output alarm is received. For example, an alarm output or response time 140, an alarm message 141, a tag 142 for uniquely connecting the alarm output and the response event, an output or response category 143, an alarm level 144, and a response It has information such as the answer 145 selected at times and the terminal number 146 of the command terminal 1 that has output or responded.

  FIG. 6E is a diagram showing an example of the diagram drawing base information log 15. The diagram drawing base information log 15 shown in FIG. 6E is output from the operation arranging server 3 at a constant cycle. The diagram drawing base information log 15 has, for example, information such as a time 150, a track record 151 of each train at that time, a prediction 152 of each station's future arrival and departure times, and vehicle operation information 153 on the diagram. .

  FIG. 6F is a diagram illustrating an example of the operation organization log 16. The driving arrangement log 16 illustrated in FIG. 6F is output from the driving arrangement server 3 when the driving arrangement is received from the diagram screen 22. For example, the time 160 when the operation adjustment is accepted, the terminal number 161 of the command terminal 1 where the operation adjustment operation was performed, the train number 162 of the train where the operation was arranged, the operation arrangement type 163 indicating the type of operation arrangement, It has information such as a station name 164 of the start or execution station of the driving arrangement, a parameter 165 such as an end station of the driving arrangement and a value after the change, a response result 166 to the request for the driving arrangement. The contents and number of parameters 165 differ depending on the operation arrangement type.

  FIG. 6G is a diagram illustrating an example of the terminal / user information log 17. The terminal / user information log 17 illustrated in FIG. 6G is output from the command terminal 1 when the commander logs in and logs out from the command terminal 1. For example, each terminal number 170 has information such as a login or logout time 171, an event 172 indicating login or logout, an ID 173 of the logged-in user, and a user name 174.

  When receiving a request for reproduction of the on-line state from the command terminal 1, the log management server 6 searches a portion corresponding to the specified time from the collected logs, edits it as necessary, and retransmits it to the command terminal 1. The command terminal 1 reproduces the state at the time of actual operation based on the log received from the log management server 6 and displays it on the screen.

As a display method of reference information such as a train control state and manual control content, there is a method of highlighting with a display color of a train and / or a track circuit on which the train is located, a shape of a figure, a balloon, an icon, and the like. In the example of FIG. 7C, the change in the display color of the train and the shape of the figure of the track circuit is used as the reference information display 313.

  FIG. 7D is a diagram illustrating a fourth example of the standing line reproduction screen 31. In the example of FIG. 7D, the reference information display 314 is displayed on the screen by a balloon.

  FIG. 7E is a diagram illustrating a fifth example of the standing line reproduction screen 31. Various methods described above with reference to FIGS. 4A to 4C may be combined as a method of displaying reference information such as the train control state and manual control content. In the example of FIG. 7E, the reference information display 311 is displayed in a dedicated area with a dialog, and the related portion of the reference information display 315 is displayed with an icon.

  Note that the reference information display method is not limited to the method shown here, and various other methods may be used. Further, a voice may be used in combination, such as ringing a short bell in accordance with the display timing on the screen.

  In the present embodiment, the time from when the reference information is displayed until the display is erased is defined separately or set arbitrarily. Moreover, the display on the screen of the confirmed reference information may be erased by the confirmation operation by the command terminal 1 displaying the reference information.

  In the present embodiment, it is assumed that the section for which the reference information is displayed can be set at the start of playback and can be set at any time during playback.

  FIG. 7F is a diagram illustrating a sixth example of the standing line reproduction screen 31. In the example of FIG. 7F, on the display condition setting screen 316, the type of reference information to be displayed, the section (station) to be displayed, and the time for continuing to display the reference information for manual route control (manual route control display time) ) And the time for continuing the display of the reference information for operation arrangement (operation arrangement display time) can be set.

  FIG. 7G is a diagram illustrating a seventh example of the standing line reproduction screen 31. As for the train control state, if reference information is displayed for all trains and all routes that are not automatically controlled, the display may be excessive. Therefore, it may be possible to set the reference information not to be displayed for a scene where it is obvious that the automatic control is not performed or a scene where the automatic control is not a problem. For example, it is obvious that the traffic signal is not automatically controlled when the train is not in the approach section as shown in FIG. 4A. In addition, regarding the delay of the train, it may be possible to set so that the reference information is displayed only for a train whose delay time is equal to or greater than a specified threshold value. In the example of FIG. 7G, on the control state display condition setting screen 317, whether or not to display reference information for each type of control state can be designated by “R”, and a train that determines whether or not to display reference information The delay threshold (delayed train limited threshold) and the time for continuing the display after the condition for displaying the reference information is not met (display duration after cancellation) can be specified in time.

  FIG. 7H is a diagram illustrating an eighth example of the standing line reproduction screen 31. Instead of displaying all trains that are not automatically controlled in parallel, only the train control state designated from the command terminal 1 may be displayed. In the example of FIG. 7H, the reference information of the train with the train number 1 and the train with the train number 4 specified in the reference information display 318 is displayed.

  FIG. 8 is a diagram showing an example of a diagram screen (hereinafter referred to as a diagram playback screen 32) to be played back in the present embodiment. Reference information is displayed on the diagram reproduction screen 32 in the same manner as the on-line reproduction screen 31 described above. As for the display method of the reference information, various methods can be considered in the same way as the standing line reproduction screen 31. In the example of FIG. 8, reference information display using a dialog (reference information display 321), reference information display using an icon, and a double line (reference information display 322) representing the playback time as reference information are displayed. It is displayed.

  When reproducing past train operations, the in-line reproduction screen 31 is mainly used, and the diagram reproduction screen 32 is assumed to be auxiliary. For example, it is possible to use such a method as temporarily switching to the diagram playback screen 32 and confirming what diagram was predicted at that time while playing the on-line playback screen. For this reason, as shown in FIG. 8, information regarding the executed operation arrangement is displayed on both the standing line reproduction screen 31 and the diagram reproduction screen 32.

  FIG. 9 is a block diagram of the log management server 6 in the present embodiment. The log management server 6 includes a log collection unit 601, a terminal operation reception unit 602, a log search unit 603, a reproduction information editing unit 604, and a reproduction information distribution unit 605.

  The log collection unit 601 collects the logs output from the business servers 2 to 5 and stores them in the log database 611. As described above, the log collection timing may be regular or when an operation of the command terminal 1 is received. When an operation for starting reproduction by designating time is performed at the command terminal 1, when this is notified to the log management server 6, the terminal operation accepting unit 602 accepts, and the log search unit 603 is designated. The log database 611 is searched based on the determined time. Here, if the condition is set in the display condition setting 612 among the logs corresponding to the reproduction time, a log satisfying the condition is extracted as a display target. The reproduction information editing unit 604 uses the extracted log to generate a standing line screen and a diagram screen and reference information, and combines them to obtain reproduction information 613 for the standing line reproduction screen and the diagram reproduction screen including the reference information. create. The reproduction information distribution unit 605 distributes the reproduction information 613 to the command terminal 1.

  FIG. 10 is a flowchart showing processing of the log management server 6 in the present embodiment.

  When the log management server 6 receives a reproduction request from the command terminal 1 in the terminal operation reception unit 602, the log management server 6 checks whether there is a problem at the specified time (step 621). If there is a problem with the time, the log management server 6 stops the process and outputs a time error (step 651).

  If there is no problem in the time, the log management server 6 checks whether there is a log at the specified time (step 622), and if there is no log at the specified time, performs log collection (step 652). As a result of the log collection, it is confirmed whether or not a log at the specified time has been obtained (step 641). If no log is obtained, the log management server 6 stops the processing and generates an error indicating that there is no log. Output (step 653).

  If there is a log at the specified time, the log management server 6 searches the log database 611 by the log search unit 603 (step 631). The log management server 6 checks whether or not the log matches the display target condition (step 623), and if not, the log management server 6 proceeds to processing at the next distribution time (step 624).

  When the log matches the display condition, the log management server 6 uses the reproduction information editing unit 604 to collate with another log searched at the same time, or search for another log using the value in this log. Then, information to be displayed on the reproduction screen is edited by specifying information from a plurality of logs (step 632).

  Then, the log management server 6 waits until the playback screen is delivered (step 633), and the playback information delivery unit 605 delivers the playback screen information to the command terminal 1 (step 634).

  When the reproduction screen information is distributed, the log management server 6 checks whether there is a log to be distributed in the next cycle (step 624). If there is no log to be distributed next, the log management server 6 stops the process and outputs an error indicating that there is no log (step 653). If there is a log to be distributed next, the log management server 6 returns to step 631 to search the log database 611 and repeats the subsequent processing in the same manner until the reproduction stop operation is performed from the command terminal 1.

  Normally, in step 623, there is no possibility that no log matches the display condition.

  Hereinafter, the relationship between each reproduction function described above and the operation of each unit of the log management server 6 will be described.

  The log collection unit 601 collects the data acquired by the business servers 2 to 5 in the operation management system in actual operation as a log and accumulates it in the log database 611. At this time, the logs accumulated in the log database 611 are various logs as exemplified in FIGS. The reproduction information editing unit 604 uses the log search unit 603 to combine the line status displayed by the operation management system in actual operation and the reference information not displayed in actual operation based on the log of the log database 611. Create an on-line playback screen. The standing line reproduction screen created at that time is a screen that displays the standing line state and the reference information as illustrated in FIGS. The reproduction information 613 indicating the standing line reproduction screen is sent from the reproduction information distribution unit 605 to the command terminal 1 and displayed there. Thereby, it becomes possible to reproduce the operation of the past train so that the relationship with the control state or the like not displayed on the screen at that time can be understood.

  In addition, the reproduction information editing unit 604 identifies a train that is not automatically controlled based on the log, and displays a line reproduction screen that displays, as reference information, that the identified train is not automatically controlled during reproduction of the line presence state. Is generated. Thereby, since the train which is not automatically controlled is clearly shown on the reproduction screen, it is possible to know the relation between the train operation status and the control. At that time, the reproduction information editing unit 604 identifies a train that is not automatically controlled based on the log, for example, by detecting the states illustrated in FIGS.

  In addition, the reproduction information editing unit 604 generates a standing line reproduction screen that displays the reason why the specified train is not automatically controlled as reference information. Thereby, it is possible to know at the time of regeneration why a train that is not automatically controlled is not automatically controlled. At that time, the reproduction information editing unit 604 displays, for example, which one of FIGS. 4A to 4F corresponds to the reason that the automatic control is not performed.

  In addition, the reproduction information editing unit 604 specifies that control has been performed based on the log, and displays the information on the control and the content of the control as reference information at the time of reproduction of the presence line state. Is generated. Thereby, train operation can be reproduced so that the relationship between train operation and control can be understood. In this case, the control specified by the reproduction information editing unit 604 is manual control, for example. Thereby, the train operation can be reproduced so that the relationship between the train operation and the manual control can be understood.

At this time, the reproduction information editing unit 604 may specify that the manual control illustrated in FIGS. 5A to 5D has been performed based on the log.

  Further, the reproduction information editing unit 604 identifies that an alarm has occurred based on the log, and generates a standing line reproduction screen that displays the occurrence of the identified alarm as reference information when reproducing the standing line state. Thereby, it becomes possible to reproduce | regenerate so that the relationship between the operation state of the past train and the condition of the warning at the time of operation can be understood. In that case, the reproduction information editing unit 604 further identifies the response to the alarm based on the log, and displays the identified line response as reference information during reproduction of the standing line state. Is generated. Thereby, it can reproduce | regenerate so that the relationship between a warning and the response with respect to the operation state of the past train may be understood.

  Also, the reproduction information editing unit 604 further creates a diagram reproduction screen that combines the diagram displayed by the operation management system in actual operation and the reference information not displayed in actual operation based on the log. The diagram reproduction screen created at this time is a screen that displays the diagram status and reference information as illustrated in FIG. Thereby, not only the in-line state but also the state of the diagram can be known together with the reference information during reproduction, and the situation can be better known.

  In addition, as the display condition setting 612, the display condition that conditions the reference information displayed on the screen is set to be changeable. The reproduction information editing unit 604 generates a standing line reproduction screen that displays reference information based on the display conditions. As a result, the display condition of the reference information can be set in an easy-to-use form.

  For example, in the display condition setting 612, the display time may be set for each item of reference information as the display condition. According to this, the display time of the reference information can be set to a value that is easy to use.

  The display condition setting 612 may specify a train for displaying reference information as a display condition. In that case, the reproduction information editing unit 604 generates an on-line reproduction screen that displays reference information for only the train specified by the display condition when reproducing the on-line state based on the log. According to this, when it is desired to know the state of a specific train at the time of reproduction, only the state of the train can be displayed as reference information, so that the state of the train can be easily known.

  In the display condition setting 612, a section for displaying reference information may be specified as a display condition. In that case, based on the log, the reproduction information editing unit 604 generates an on-line reproduction screen that displays reference information only for the section specified by the display condition when reproducing the on-line state. Thus, when it is desired to know the state of the train and equipment in a specific section during reproduction, only the state of that section can be displayed as reference information, so that the state of that section can be easily known.

  The display condition setting 612 may specify the type of state for displaying reference information as the display condition. In that case, based on the log, the reproduction information editing unit 604 generates an on-line reproduction screen that displays reference information for only the type of state specified by the display condition when reproducing the on-line state. Thus, when it is desired to know a train or facility in a specific state at the time of reproduction, only the train in that state can be displayed as reference information, so that the state can be easily known.

  As described above, according to the present embodiment, by adding reference information to the current situation from the log information collected during operation and reproducing it on the command terminal 1, investigation of the cause of the incident, more appropriate incident solution and advance avoidance measures It can be used for searching for information, educating commanders, investigating system bugs, etc. Visualizing and displaying the control state of the train on the terminal screen that is being played back makes it easy to identify the train that caused the disturbance and the reason for it, and this is a guideline for determining the order and timing to be dealt with. In addition, by displaying the contents of manual control performed during actual operation on the terminal screen being reproduced, it is possible to distinguish between a train that is being automatically controlled, a train that is manually controlled, and a terminal that has been manually controlled. With these reference information display functions, the playback function can be used more effectively.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the spirit of the present invention.
