Abstract

A data input device is capable of displaying the control state of a traffic signal on a train diagram by acquiring train operation information from a diagram information database (201), creating a train line, displaying the train line on an operation arrangement input device (1), and bringing the train diagram and the control state of a traffic signal to be controlled next by the train into correspondence from control state determination processing (209) and indication display position determination processing (210). As a result, the content of operation arrangement can be determined simply by looking at the display on the operation arrangement input device, thereby making it possible to achieve the prevention of input errors in the operation arrangement, and the input of urgent operation arrangement.

Description

TECHNICAL FIELD

The present invention relates to a data entry support device and a data entry support method for displaying graphic data such as the train lines (lines) in a train operation diagram, and more particularly to a data entry support device and a data entry support method that display a route control status on a train line to reduce the time required for judging the entry contents of a traffic schedule change and to allow an operator to readily enter a traffic schedule change that need immediate processing.

BACKGROUND ART

A conventional train traffic management system, which controls trains based on a diagram, judges the contents of an entered diagram change based on the information from the traffic schedule change entry screen, on which graphic data such as the train lines of the train operation diagram are displayed, and on the information from the operation control display screen on which graphic data, such as the train locations and the route control status, is displayed in the interlocking table.
In this case, the operator must search the operation control display screen for the number of a train to which a traffic schedule change is to be applied, check the control status of the route on which the train is to travel and, after that, enter a traffic schedule change from the traffic schedule change entry screen. To do so, the operator must compare the information displayed on multiple screens for comprehensively checking information necessary for the traffic schedule change processing and, so, the operator sometimes makes an entry error in which case re-entry operation is necessary- Another problem is that judging the contents of an entered traffic schedule change takes long and so, during the traffic schedule change processing that needs immediate processing, the train may pass the location, to which a traffic schedule change is to be applied, before data is entered.
One way to solve this problem is to add information, other than train lines, to the traffic schedule change entry screen. One of conventional traffic schedule change entry screens is disclosed, for example, in Patent literature 1. In this method, a location is specified on the train schedule diagram, and the predicted route map screen display data, which indicates the predicted train operation corresponding to the time and the location on the route calculated by the location specification unit, is displayed on the traffic schedule change entry screen, on which the train schedule diagram is displayed, as the predicted route map screen in the route map format.
Another method is disclosed in Patent literature 2. In this method, when the travel result of the train schedule diagram is displayed, the travel result is captured for each track circuit and the result diagram, in which the length of each track circuit is reflected, is displayed to allow the operator to identify the location of the train on the train schedule diagram.

SUMMARY OF INVENTION

TECHNICAL PROBLEM

In the method disclosed in Patent literature 1, because a location is specified on the train schedule diagram to acquire information necessary for changing the traffic schedule, the control status display range is limited to a part of the range for which the dispatcher is responsible. In addition, displaying both the train schedule diagram and the predicted route map on the same screen requires the dispatcher to compare the displays, sometimes preventing the dispatcher from taking action for a traffic schedule change that need immediate processing.
In the method disclosed in Patent literature 2, the location of the train can be identified on the train schedule diagram but the route control status at each station is not displayed on the train diagram display device. This requires the dispatcher to reference the operation control display screen to understand the route control status, sometimes preventing the dispatcher from taking action when the train is in the control range of a station and a traffic schedule change must be entered immediately.
It is an object of the present invention to provide a data entry support device and a data entry support method that display information, necessary for judging the entry contents of a traffic schedule change, on one display device to reduce the time required before entering the traffic schedule change to solve a train schedule disruption problem.

SOLUTION TO PROBLEM

To achieve the object described above, a data entry support device and a data entry support method of the present invention comprehensively display information, necessary for judging the contents of a traffic schedule change, on the traffic schedule change entry screen by displaying a route control status, which will be controlled next by a train, on the train line on the traffic schedule change entry screen.

ADVANTAGEOUS EFFECTS OF INVENTION

The present invention prevents an entry error when a traffic schedule change is entered and reduces the time required for judging the contents of the entry, thus allowing the dispatcher to process a traffic schedule change that needs immediate processing and to enter a traffic schedule change without delay.
Other objects, features and advantages of the present invention will become apparent from the following description of the embodiments according to the invention taken in conjunction the accompanying drawings.

DESCRIPTION OF EMBODIMENTS

One embodiment of the present invention will be described with reference FIG. 1 to FIG. 5 using an example of a traffic schedule change device on which a train operation diagram is displayed.
FIG. 1 is a diagram showing the configuration of a train traffic management system that manages train operation. As shown in FIG. 1, the train traffic management system in this embodiment comprises a traffic schedule change device 1 that displays a train operation diagram, receives a train operation change, and displays a train operation result on the train operation diagram, station control devices 2 such as station systems each of which controls the routes at a station or on rail tracks or controls the train operation, and a train operation management device 3 that manages the train operation, relays data between the traffic schedule change device 1 and the station control device 2, and checks data consistency. Those devices are connected via a network.
The traffic schedule change device 1 receives information on the train operation and displays the information on the display as the train operation diagram to support the entry of a train operation change (also called a traffic schedule change). The contents of a change in the train operation entered into the traffic schedule change device I are sent to the station control device 2 via the train operation management device 3. The station control device 2 controls the operation of the routes and trains based on a train operation change received from the train operation management device 3.
FIG. 2 is a processing block diagram of the traffic schedule change device in this embodiment FIG.2 shows an example of the required configuration and other components may be added as necessary.
As shown in FIG. 2, the traffic schedule change device 1 has a train operation information database 201, a train location information database 202, a train route information database 203, and a signal aspect information database 204, and comprises a control information reception unit 205 that receives control information from the station control device 2, a train operation information reception unit 206 that receives train operation information from the train operation management device 3, a train operation change processing unit 207 that changes the train operation based on received traffic schedule change information, a train schedule diagram data creation processing unit 208 that creates train schedule diagram data from the train operation information, a control status judgment processing unit 209, a signal aspect display position judgment processing unit 210, and a display processing unit 211 that displays data on a display 212.
The train operation information database 201 stores train operation information received by the train operation information reception unit 206, and the train location information database 202 stores received train traveling locations. The signal aspect information database 204 stores control information received by the control information reception unit 205.
The control status judgment processing unit 209 judges the route control status (signal aspect), which will be controlled next by a train being processed, based on the information in the train location information database 202, train route information database 203, and signal aspect information database 204.
The signal aspect display position judgment processing unit 210 calculates a position in the train schedule diagram data, created by the train schedule diagram data creation processing unit 208, where the route control status of a train determined by the control status judgment processing unit 209 is displayed.
FIG. 3 is a diagram showing an example of the screen of the display 212. On the display 212, the operation plan information is displayed as train lines 30 with station names on the vertical axis and the time on the horizontal axis, and a route control status 31 is displayed on the train line 30 to support the dispatcher in the traffic schedule change operation.
The route control status 31 indicates, in color, the control status of a route which is one of the arrival routes or departure routes to be controlled next by each train and which is near to the location of the train. This display allows the operator to immediately understand the status of a train to which a traffic schedule change is to be applied.
In this embodiment, the train schedule diagram managed by the traffic schedule change device 1 on a train basis is made to correspond to the control status of a route, which is a facility in the field, to allow the route control status to be displayed on the train schedule diagram. The following describes the flow of processing for establishing the correspondence between the train schedule diagram and the route control status with reference to FIG. 4.
FIG. 4 shows the outline of the processing flow of the control status judgment processing unit 209 that judges the signal aspect that will be controlled by a train to be processed and the processing flow of the signal aspect display position judgment processing unit 210 that judges the location at which the route control status is displayed on the train schedule diagram.
First, the following describes the processing flow of the control status judgment processing unit 209. In step 402, the control status judgment processing unit 209 acquires train numbers from the train operation information database 201 and, in step 403, selects a train number to be processed. In step 404, the control status judgment processing unit 209 acquires the train location information corresponding to the train number selected from the train location information database 202 and, in step 405, acquires the train route information from the train route information database 203.
In step 406, the control status judgment processing unit 209 judges the train location from the acquired train location information and passes control to one of the three, (1) to (3), according to the train location.
(1) When the train is at a location between the departure route and the control point, control is passed to step 407 and the signal aspect is set to "red".
(2) When the train is at a location between the control point and the arrival route, control is passed to step 408 and the route to the arrival track is acquired from the train route information acquired in step 405. The signal aspect status information on the route on the acquired route is obtained from the signal aspect information database 204, and the signal aspect of the arrival route is used as the signal aspect.
(3) When the train is at a location between the arrival route and the departure route, control is passed to step 410 and the arrival track is obtained from the train route information acquired in step 405. The signal aspect of the departure route corresponding to the acquired track number is obtained from the signal aspect information database 204 and the obtained signal aspect is used as the signal aspect.
Next, the following describes the processing flow of the signal aspect display position judgment processing unit 210. In step 412 of the processing flow, control of the processing flow is passed to one of the two, (1) and (2), according to the train location acquired from the train location information database 202.
(1) If the train is at a location between the arrival route and the departure route, control is passed to step 413 and the control status is displayed on the train line that indicates the departure time at the station at which the train is located.
(2) If the train is at a location not between the arrival route and the departure route, control is passed to step 414 and the control status is displayed on the train line that indicates the arrival time at the next station of the station at which the train is located.
A check is made in step 415 if there is another train number to be edited. If there is no train number to be edited, control is passed to step 416 to terminate the processing; if there is another train number to be edited, control is passed back to step 403.
Referring to FIG. 5, the following describes the processing for relating a train number to the arrival track, train location, and the route to the arrival track corresponding to the train based on the train operation information database 201, train location information database 202, and train route information database 203.
The train operation information database 201 has a train operation information table 501 that manages the stop stations, arrival times, departure times, and arrival tracks for each train number. The train location information database 202 has a train location information table 502 that manages the train-located station name and the track circuits for each train number. The train location information database 202 may be related to the train operation information database 201 by the processing in step 404 in FIG. 4 using the train number as the key.
The train route information database 203 has a train route information table 503 that manages, for each train number, the track circuits on which the train travels and the facility information and the route names corresponding to the track circuits. The train route information database 203 may be related to the train location information database 202 by the processing in step 405 in FIG. 4 using the train number and the track circuit as the key so that the track circuits on which the train travels, the facility information, and the route names may be acquired. Therefore, executing a sequence of processing from step 404 to step 405 allows the arrival track, the train location, and the route to the arrival track corresponding to a train to be acquired.
In this embodiment, the train operation is related to the route control status, which will be controlled next by the train, to display the route control status on the train operation diagram. This allows the dispatcher to judge the entry contents of a traffic schedule change, which have conventionally been acquired from multiple terminals, on the traffic schedule change entry screen alone.
As described above, the traffic schedule change device in this embodiment prevents an entry error and allows the dispatcher to take action on a traffic schedule change that needs immediate processing.
When this embodiment is applied to a device on which a train operation diagram is displayed and a traffic schedule change is accepted, the control status of a route can be displayed on a train line. And, so, this configuration allows the dispatcher to judge the contents of a traffic schedule change simply by viewing the display on the traffic schedule change entry device, thus preventing an entry error and making it possible to accept a traffic schedule change that needs immediate processing.
It should be understood by those skilled in the art that although the foregoing description has been made on the embodiments of the present invention, the invention is not limited thereto and various changes and modifications may be made without departing from the spirit and the scope of the appended claims.
