Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of changing a train operation plan in order to deal with a delay of a train in the operation management of a railway. It relates to a system that supports creation work.

[0002]

2. Description of the Related Art In railway facilities, a switch and a signal are controlled in accordance with a predetermined operation plan, and the train operation is managed so that a train operation according to the operation plan is obtained. At this time, a route control device that controls these switches and signals by a computer is used. The route control device refers to the operation plan and determines the departure order of trains and the order of trains. The control is performed by paying attention to.

[0003] Disturbances in train operation occur not only when an accident or a failure occurs, but also when the weather changes, for example, rain and wind. Although this occurs, such a change in the operation plan performed during the normal operation of the train is referred to as traffic rescheduling, and this is usually processed by the change in the operation plan referred to by the route control device.

[0004] Therefore, the work necessary for the traffic control will be described. This work is composed of two stages, that is, the work of drafting an operation plan change plan and the work of changing the operation plan referred to by the route control device. The work of drafting the operation plan change plan at this time is a work of examining various plans and finding an optimal change plan while considering train performance and train interval, etc., and proceeding through trial and error. It will be going to work.

[0005] In addition, in the traffic control, it is necessary to change the operation plan including suspension of operation and the construction of a temporary train. At this time, even a slight change often affects the entire line. It is customary to draft a change plan for the operation plan that is consistent over the entire line at one location. At this time, when drafting a traffic rescheduling plan using a diagram drawn on paper (diagram), a plurality of dispatchers may negotiate, but in principle, one diagram diagram A traffic control plan is drafted using

In recent years, a method of using a workstation (computer terminal) to perform work on a diamond figure displayed on a display surface instead of a diamond diagram has been introduced in order to support the operation planning work. As a result, it has become possible to greatly improve the efficiency of the operation planning work.

By the way, in the case of the prior art using this workstation, the operation scheduling plan is made such that only one workstation that manages all lines in the operation management system is used. ing.

[0008]

The above prior art uses a plurality of workstations and does not consider the operation rescheduling planning work in cooperation with a plurality of dispatchers. There was a problem with quick and accurate response. In other words, in the prior art, the operation rescheduling drafting work is performed only in the operation management system for managing all the lines.
It is designed to be performed using two workstations, so that even in the case of a large-scale operation plan change, it is not possible to carry out collaborative planning work by multiple dispatchers, so that quick and accurate work cannot be obtained. is there.

[0009] This is because, when a plurality of workstations are used to independently prepare operation rescheduling plans for the same line section, there is a method for resolving inconsistency in a part where the rescheduling plans are related. Because it is not the prior art,
For this reason, even if the disturbance of train operation is very large and widespread, the operation control plan must be drafted with only one workstation. It will be.

[0010] If the same operation plan is corrected by the cooperation of a plurality of dispatchers using a plurality of computer terminals, the work can be carried out more efficiently, but in this case, the technology is in charge of each terminal. It is necessary for the dispatchers to understand each other's work well, otherwise, for example, the dispatcher in charge of a certain computer terminal changed the train departure order at a certain station Later, when trying to cancel the operation, if the order of the trains has been changed by another dispatcher, both operations may affect each other, and the operation may not be canceled.

An object of the present invention is to provide an operation plan correction system which enables a plurality of computer terminals to easily perform an operation arrangement drafting work for the same operation plan by the cooperation of a plurality of dispatchers. It is in.

[0012]

The above object is achieved by the present invention.

As a result, in a system for assisting in planning a traffic rescheduling plan using workstations and the like, a plurality of commanders use a plurality of workstations and the like to control the same track section or the related track sections. At the time of planning work by trial and error of the traffic rescheduling plan, the operation content at each terminal is displayed on other terminals.

More specifically, the operation history at each terminal can be checked at all terminals. Further, when a change input at one terminal affects another terminal, the operation history is stored in the terminal. Thus, the operation corresponding to the change input is displayed in an emphasized manner.

[0015] Therefore, the operation contents at each terminal can be immediately confirmed, and the planning work by trial and error of the driving arrangement plan using the plurality of terminals by the plurality of commanders can be performed efficiently and smoothly. it can.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An operation plan correction system according to the present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment of the present invention, which includes two traffic control terminals 1 and 2 each composed of a computer terminal, which are connected to a route control device 3 and a network 4 respectively.

The traffic rescheduling terminal 1 and the traffic rescheduling terminal 2 are each configured around a computer (not shown), and include display devices 101 and 201 and keyboards 102 and 2.
02 and data input means consisting of mice 103 and 203 are provided so that a commander can perform an operation plan change plan proposal.

The route control device 3 outputs a signal for controlling a switch or a traffic signal in accordance with a control operation plan stored therein. When a desired operation plan change plan is created by the traffic rescheduling terminal 1 and the rearrangement rescheduling terminal 2,
As a result, the control operation plan stored in the route control device 3 is rewritten and changed.

The network 4 is for exchanging information among the traffic control terminals 1 and 2, and the route control device 3. In this embodiment, the number of traffic control terminals is two, but the system configuration can be exactly the same with three or more traffic control terminals.

Next, the internal configuration of the traffic control terminals 1 and 2 will be described in detail. In this embodiment,
Since the traffic control terminal 1 and the traffic control terminal 2 have the same configuration, the traffic control terminal 1 will be described. The traffic control terminal 1 displays a diagram on the screen of the display device 101,
A train is directly specified on the diagram display surface by a pointing device such as the mouse 103, and a change input for the train is given by an operation using the mouse 103 or an operation using a menu.

Such a traffic control terminal is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 8-244615, and will not be described in detail. However, the traffic control terminal 1 uses a timetable representing a train operation plan. In the figure, a streak, which is a locus of the movement of a train, can be arbitrarily drawn by directly operating data input means such as a mouse, so that a change in an operation plan can be obtained.

A display device 101 comprising a graphics display has a function of displaying a diagram, a keyboard 102 is used for inputting a change in an operation plan, and a mouse 103 has at least one button. And
By using a pointer that moves on the screen of the display device 101 in conjunction with the movement of the mouse 103, a figure displayed on the screen is selected (picked), and input for movement is performed.
(Drag) works.

The display information judging means 104, based on the change input data supplied from another traffic rescheduling terminal (here, the traffic rescheduling terminal 2), causes the display device 101 of its own terminal to perform a change operation at another terminal. It is determined whether to display the history information. The change plan storage unit 105 serves to store the change plan data of the operation plan. The contents of the data are data such as the arrival and departure times and the passing times of each train at each station. This operation plan change plan data changes. When the operation plan change plan data is approved, the changed new operation plan is transferred to the route control device 3.

The operation plan change means 106 changes the operation plan change plan data in the change plan storage means 105 in accordance with the operation plan change request. The network control means 107 executes necessary control when connecting the traffic rescheduling terminal 1 to a network. The route control data storage unit 108 stores operation plan data. Route control data changing means 109
Changes the operation plan data stored in the route control data storage unit 108.

Although not shown, as described above, each of the traffic rescheduling terminals 1 and 2 is constituted mainly by a computer, and includes change plan storage means 104, change plan storage means 105, and operation plan change means. 106, the network control means 107, etc. are all connected by an internal bus. Therefore, in this embodiment, each of the traffic control terminals 1, 2
Various processes described below are executed by a computer inside the computer.

First, a description will be given of the change of the operation plan and the flow of the diagram display processing according to this embodiment.
In this embodiment, the operation plan and the change plan of the operation plan are distinguished from each other and stored by different means, and
First, a change plan for an operation plan is created, and then, when it is determined that the plan is appropriate, the operation plan is approved.

First, a flow of processing for creating a change plan of an operation plan will be described. When a change in train departure time or a change in train departure order is input from the keyboard 102 and the mouse 103, the operation plan changing means 106
The contents of the change plan storage unit 105 are changed according to the change of the operation plan input from the keyboard 102 and the mouse 103.

The storage contents of the change plan storage means 105 are data such as the arrival and departure times of trains and passing times. Based on these data, a diagram showing an operation plan is displayed on the display device 1.
01 is displayed on the display surface.

Next, the flow of approval will be described. An operation plan change plan becomes an operation plan when it is approved, and is executed for the first time. This approval process is as follows. When the approval of the operation plan change is input from the keyboard 102 and the mouse 103, the change plan stored in the change plan storage unit 105 is transferred to the route control device 3 by the network control unit 107.

Therefore, the route control data changing means 108 in the route control device 3 changes the route control data in the route control data storage means 109 based on the proposed change. As a result, the operation plan is changed for the first time, and a signal for controlling the switch and the traffic signal is output based on the changed operation plan.

Next, an example of displaying a diagram by the display device 101 will be described. This diagram is, as described above, a diagram that, as is well known, arranges the stations existing on the train travel line in order along the vertical axis and takes time on the horizontal axis, thereby FIG. 4 is a diagram in which movement between stations can be represented by a straight line (streak), and thereby the train operation state is represented.

FIG. 2 shows an example of a diagram on the image plane of the display device 101 of the diagram created for the traffic control according to this embodiment. Here, first, the pointer 201
The pointer of the mouse 103 is shown. Next, point 202
Is a control point indicating that the train departs from station B and the departure time. And the lines 203 and 20
Reference numerals 4 and 205 indicate the running trajectories of the respective trains.

Next, a description will be given of the operation of inputting the change of the operation plan using the menu, taking the change of the train order as an example.
Note that the operation here corresponds to an operation for changing a change plan of the operation plan. First select the reorder menu. That is, in FIG.
1 is moved to the menu selection area 206, the pull-down menu is expanded as shown in the figure, the pointer 201 is moved to "order change", and the mouse button is released, to display a change data input area 207.

Therefore, after moving the pointer 201 on the changed data input area 207, the train station is changed by inputting the changed station and the changed train number using the keyboard 102.

Next, with respect to the input operation of the operation plan change by the mouse 103, the operation of changing the train order is taken as an example.
This will be described with reference to FIG. The operation here corresponds to the change of the change plan of the operation plan, and the processing procedure at this time is as shown in FIG. 4 and is executed by the computer described above.

Step 401: Specifying a train to be changed First, a train to be changed is specified. That is, mouse 1
When the pointer 201 is moved over the train line 203 in FIG. 3 and a mouse button is clicked in FIG. 3, the train line 203 is changed to a thick line by this operation. This display state indicates the train to be changed,
This indicates that the train corresponding to the train line 203 is designated.

Step 402: Change input processing Next, a change in train order is input. That is, in FIG. 3, when the pointer 201 is moved over the control point 202 and the mouse button is pressed, the control point 202 becomes movable. Next, if the pointer 201 is moved while holding down the mouse button in this movable state,
In response, the control point 202 moves on the diagram. Then, after the control point 202 is moved to a position representing a desired time on the B station over the control point 301, the mouse button is released to release the B station of the train corresponding to the train lines 203 and 204. Can be changed.

Step 403: Simulation Process for Resolving Conflicts Lastly, control points other than the control points 202 are controlled so as not to contradict the control points 202 after the change. Make changes so that the minimum time interval between trains is maintained. At this time, if an inconvenience such as a plurality of trains using the same arrival / departure number line at the same time or an inability to secure time for a return occurs, a warning mark is displayed. .

Next, a problem that occurs when working in cooperation with a plurality of terminals will be described using a specific example. First, here, the traffic control terminal 1 is in charge of Kou station,
It is assumed that traffic control terminal 2 is in charge of Otsu station. Now, it is assumed that the departure order of the trains at the instep station and the adjacent station, Otsu station, are as follows: train A: train 1, train B: train 2, train C: train 3. At this time, from the traffic control terminal 1,
A command to change the departure order of the A train and the B train at the A station is input, whereby the departure order of the trains at the A station and the Otsu station becomes B train: 1, A train: 2, C Train: Suppose the order was 3rd.

Next, the traffic control terminal 2 sends the A
Assuming that a command to change the order of the train and the C train is input, in this case, the departure order of the trains at the first station and the next station, the second station, is as follows. : Train No.2, Train C: Train No.3 Otsu Station → Train B: Train No.1, Train C: Train No.2, Train A: Train No.3.

Here, if the command to change the departure order of the A and B trains at the first station at the first station has been canceled from the traffic reordering terminal 1, the order of the train at the first station and the next station are cancelled. The train order at Otsu Station could not be handled, resulting in inconsistency in the train operation plan.

As a result, in order to prepare a change plan of the operation plan by trial and error using a plurality of terminals in cooperation,
It is necessary for the dispatcher to grasp the change operation at each terminal, but in the prior art, this point was not taken into account, and as described above, it was difficult to draft a traffic control plan in cooperation with multiple dispatchers. Thus, a problem arises in the point of quick and accurate response to a large-scale operation plan change.

In this embodiment, however, the input of the operation plan change made by the traffic rescheduling terminal 1 is immediately reflected on the traffic rescheduling terminal 2 when drafting the operation plan change plan. The operation plan change input performed in (1) is configured to be reflected in the traffic rescheduling terminal 1, and this is characterized in that the problem in the prior art is solved. Will be described more specifically with reference to the above embodiment.

First, in this embodiment, when each dispatcher is in charge of a plurality of traffic dispatch terminals, each dispatcher grasps the operation at another traffic dispatch terminal as follows.
A method of acquiring operation history information in another traffic rescheduling terminal is used. In addition, here, each traffic control terminal,
In this example, a section extending over a plurality of stations is set as a section in charge of the terminal.

FIG. 5 shows a method of displaying an operation history at another traffic control terminal in each traffic control terminal. FIG. 5 shows a display screen of the display device 101 in the traffic control terminal 1. is there. And first, here, 501
And 502 are operation history displays, and one operation history display 501 is shown.
Is a diagram showing the history of the change operation performed by the dispatcher in the traffic rescheduling terminal 1 as a diagram of a section in which the traffic rescheduling terminal 1 is in charge.
2 shows a history of operations performed by the dispatcher of the traffic rescheduling terminal 2 as a diagram of a section in which the traffic rescheduling terminal 2 is in charge.

Next, reference numerals 503 and 504 denote highlighting, which function to highlight each changed display by blinking display, different color display or the like when mutual changes affect each other. That is, in the case of FIG. 5, the change (operation suspension) at the traffic rescheduling terminal 2 is highlighted 50.
4. The change (order change) of the traffic control terminal 1 is highlighted 5
03 indicates that the change in the traffic control terminal 1 is affected by the change in the traffic control terminal 2.

Next, a processing procedure necessary for displaying the operation history shown in FIG. 5 will be described with reference to FIG. This process is also executed by the computer in each terminal described above. Step 601: Change input processing Each time a menu or an operation plan change input operation using a mouse is performed at each terminal, change input data is fetched from the keyboard 102 or the mouse 103 accordingly.

Step 602: Transfer processing to each terminal The captured change input data is transmitted to the display information judging means 1 of the own terminal via the network control means 107 of each terminal.
04, and further to the display information determining means 104 of another terminal via the network 4.

Step 603: Recording process of change information The display information judgment means 104 of each terminal converts the transmitted change input data into terminal ID data for identifying from which terminal the change input data was transmitted. And absolute order data indicating the order of the change input in all the terminals, and these data are recorded in the change plan storage means 105.

Step 604: display processing of change history Change input data stored in the change plan storage means 105;
The terminal ID data and the absolute order data are read out, and based on these data, a change history 501 including a plurality of character strings representing a correction operation history of a train operation plan at each terminal is displayed on a display surface of the display device 101. The process of displaying the change history 502 is executed by the display information determining unit 104.

In parallel with this, it is determined whether or not the change input data at this time has an effect on the operation included in the operation history at each terminal. The display information determination unit 104 causes the display information determination unit 104 to execute processing for displaying the highlighting 503 and the highlighting 504 on the surface. At this time, the display information determination unit 104 determines whether the operation is affected as follows.

That is, when a change input operation is performed on any terminal and the arrival / departure order of trains in a section in which the terminal is in charge is changed, the display information determination means 104 is recorded in the change plan storage means 105. Based on the past change input data, perform the process of canceling the operation on the terminal in order from the most recent operation, and when the operation cannot be canceled, judge that the operation is affected It is.

For example, if the change of train arrival / departure order cannot be returned by the operation of canceling the operation of the train at another terminal, it cannot be canceled, so it is determined that the operation is affected. Will be.

Further, here, a diagram display 50 is shown.
5. On the diagram display 506, the display information determining means 104 executes a process of reproducing past operations in a step-by-step manner. Therefore, first, the past change input data recorded in the change plan storage means 105 is fetched, and based on the fetched data, the operation performed on the terminal is known, and the operation is canceled in order from the most recent operation. To go.

Then, in order to eliminate the inconsistency on the diagram, the same inconsistency elimination simulation processing as the processing in step 403 of FIG. 4 is executed, and then a series of canceled operations is executed. The series of operation history above is reproduced.

In this case, when a change input at a certain traffic control terminal affects a change input at another terminal, in this embodiment, such a change input operation is performed as shown in FIG. As shown, the display shown by the warning display 701 is configured to appear on the diagram of the display device 101.

Here, the case where a change input at a certain traffic control terminal affects a change input at another terminal means that a change input at a certain traffic control terminal causes arrival at a train station at another terminal. This refers to a case where the dispatch order has been changed.

Therefore, according to this embodiment, not only the diagram of the own section is displayed on the display screen of the self-driving arrangement terminal, but also the operation history of the other terminal and the operation history of the other terminal. The state of interference with the operation and the state of reproduction of the operation history on the diagram are displayed.
By simply looking at the screen, the operation status of another terminal can be immediately grasped.

As a result, according to the above-described embodiment, it is easy to perform a traffic control planning work in cooperation with a plurality of dispatchers using a plurality of traffic control terminals, and to quickly and accurately change a large-scale operation plan. There is an effect that it can respond.

[0060]

According to the present invention, not only the diagram of its own section is displayed on the display screen of the self-driving arrangement terminal, but also the diagram of another terminal as required. The operation history of the terminal itself, the state of interference with operations on other terminals, and the reproduction of the operation history on the diagram are displayed. The operation status at the time can be grasped, and as a result, the operation planning can be easily performed by the cooperation of multiple dispatchers using multiple operation arrangement terminals, and quick and accurate response can be made even when a large-scale operation plan is changed. Can be.
