Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The interlocking device is a device for controlling railway circuits, traffic lights, turning devices, etc. as a railway security facility to prevent contact accidents and derailment accidents of trains and vehicles. The present invention relates to a method for supporting the creation of interlocking logic installed in an interlocking device.

[0002]

2. Description of the Related Art In a railway, for safe operation, it is confirmed that there are no other trains or vehicles in the section where trains or vehicles are scheduled to pass, and the rolling device is switched to the direction in which it is scheduled to pass. In order to prevent other trains / vehicles from entering during traffic, a traffic permit signal is displayed on the traffic light to allow trains and vehicles to pass. The section where traffic is permitted is called a route.

When ensuring safety with this method,
The interlocking logic describes how the track circuit / roller etc. should be associated and operated.

[0004] When the railroad tracks inside a station (stop) are complex and operate a plurality of trains or vehicles at the same time, it is extremely dangerous to handle this logic only with human attention. Therefore, interlocking devices equipped with this interlocking logic have come to be installed.

When designing interlocking logic, it is important to recognize the relationship between tracks. The relationship of course means a relationship in which there is a competing occupation range and traffic cannot be permitted at the same time. Normally, multiple trains and vehicles are operated at the same time, so that the areas occupied by the routes should not overlap as much as possible.
Also, when overlapping, they must be designed so that they cannot pass at the same time. Furthermore, it is also important in operation management. Because at the same time, I can't draw
If you try to pull them at the same time without deciding the order, you can prevent the accident by the interlocking logic, but trains and vehicles can not move, because the operation is disrupted.

As described above, it is indispensable to obtain the relationship between the routes from the viewpoint of interlocking logic design and operation management. In the past, however, the designer traces the wiring schematic diagram with his or her hand to see the relationship. I was extracting. Tracking more than one path at the same time was a heavy burden for humans.

As a conventional technique, there is a drawing or plotting tool as a method for supporting the creation of an interlocking diagram that expresses interlocking logic.

Japanese Unexamined Patent Publication No. 8-239042 discloses a route in which logical bit pattern information is formed and stored for each constituent element of a route, and a competition between routes is determined based on a logical operation processing result between the logical bit pattern information. There was a selection controller.

Further, in Japanese Patent Laid-Open No. 2000-137624, a test for verifying whether the control of the field device by the mounted interlocking device follows the described interlocking logic with respect to two specified specific paths. There was a device.

[0010]

As a method of supporting the creation of the interlocking table, there is a method of using a tool for drawing or a table, but this only supports the stage of clean copy and does not change the design load. It was Although there is a device for judging competition in the route selection control device, it is only possible to judge the presence or absence of competition, and there is no method for recognizing a course relationship including the situation of competition. In addition, in the device that verifies the implemented interlocking device, there is a test device that verifies the control relationship between the binary paths using the established interlocking table, but it is not a method that supports the stage of designing the interlocking logic. It was

The object of the present invention is to describe the contents of the interlocking table,
That is, it is to facilitate the work of recognizing the relationship of paths at the stage of creating the interlocking logic.

[0012]

In order to achieve the above-mentioned object, the interlocking logic creation support apparatus of the present invention uses data of a track circuit which is a minimum unit for detecting a train or a vehicle for security.
The data of the route defined as the route that a train or vehicle can pass in the track circuit, the data of the turning device that allows the train or vehicle to pass in the specified direction at the branch point of the track, the train or vehicle that secures the safety within the protection range. From equipment data composed of traffic signal data that allows traffic to pass, data such as route name, track circuit data within the protection range, route data within the protection range, route data below the contact limit, and locking lock Data generation unit for generating path data composed of data of a vessel, path names, competing track circuit data, competing path data, competing rolling devices between a plurality of paths from the course data The relationship information of the path and the relationship information generating section of the path for generating the relationship information composed of the data of the turning device which has the same direction and is not on the competing track circuit. Show conditions And a tabular relation information output section of the path for outputting further on a wiring schematic symbolically.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

The process flow of the present invention is shown in FIG. The interlocking logic creation support apparatus according to the present invention inputs the equipment data 10
Need 4

FIG. 2 is a schematic wiring diagram. The line indicates the track. The line delimiters indicate the boundaries of the track circuits, and the numbers on the lines indicate the names of the track circuits. A track circuit is a section in which rails are separated as a minimum unit for detecting trains and vehicles for security. The mark with a cross in the circle indicates the traffic signal, and the numbers beside the traffic signal indicate the name of the route, the track circuit name of the starting point of the track, and the track circuit name of the ending point. The three lines at the branch of the track, so-called vanes, indicate that there is a tumbler and that the direction with the vanes is the orientation and the direction without the vanes is the inversion. The orientation refers to the direction in which the troll device is normally open, and the inversion refers to the direction opposite to the orientation. The number beside the blade indicates the name of the rolling device.
Also, the crosses indicate that adjacent track circuits are separated by a distance less than the contact limit of the vehicle.

Taking the schematic wiring diagram shown in FIG. 2 as an example, an example of the contents of the equipment data 104 will be described with reference to the tables of FIGS.

An example of the contents of the equipment data 104 is shown below.

The equipment data 104 are track circuit data 1041 shown in FIG. 4, route data 1042 shown in FIG.
7 is composed of the switch data 1043 and the traffic signal data 1044 shown in FIG.

There is only one path through which a train or a vehicle can pass in a track circuit, that is, a track circuit without a branch, that is, a track circuit with a branch, if there is no turning device.
That is, there are a plurality of cases including a turning device. Therefore, it is not possible to recognize the route along which a train or a vehicle passes on a track circuit unit basis. Therefore, in the present invention, each of the routes that the trains and vehicles can take is defined as a route. A path corresponding to the track circuit of FIG. 2 is shown in FIG. When a rolling device exists in the track circuit like the track circuit 10T or 11T, a plurality of routes 10T-
There are 1,10T-2, 11T-1, and 11T-2.

The track circuit data 1041 holds track circuit names for all track circuits in the range to be considered.

The route data 1042 includes a route name, a left adjacent route name, and a left adjacent route name for each of all routes in the consideration range.
The name of the adjacent route on the right side, the route that is less than the contact limit from this route, and the name of the track circuit that includes this route are held.

The turning device data 1043 includes a turning device name, a localization path name, an inversion path name, and a simultaneously controlled turning device for each of all the turning devices in the range to be considered. The name is retained. A localization route is a route that a train or vehicle can take when the turning device is localized. An inversion route is a route that a train or vehicle can take when the turning device is in an inversion.

The traffic signal data 1044 holds a route name, a starting track circuit name, and a starting track circuit name for each of all the traffic signals in the range to be considered. The origin track circuit is the track circuit immediately before the traffic signal permits the approach, that is, the track circuit existing before the approach, and the destination track circuit is the track circuit at the end where the traffic signal permits the approach. That is. In this embodiment, the route 1R from 4T to 9T,
The three paths of the path 2L from 15T to 7T and the path 3L from 15T to 14T will be defined and described as an example.

From the above equipment data 104, the course data 106 is generated using the processing unit 105 described below.

FIG. 8 shows an example of the contents of the route data 106.

First, the route name column of the route data 106, the track circuit column within the protection range, the route column within the protection range, and the route column below the contact limit will be described below.

In the processing unit 105, the traffic signal data 104
The route name of No. 4 is held in the route name column of the route data 106. Furthermore, from the route data 1042 holding the track circuit name that matches the starting track circuit and the ending track circuit,
The routes immediately before and after the route are detected. Next, the search for the adjacent route is repeated from the immediately preceding route to the left and right sides.
If the trailing route can be reached, the routes except the preceding route are retained in the route name column within the protection range. Then, a track circuit including a route within the protection range is searched and held in the track circuit name column within the protection range.
Further, the track circuit additionally designated by a person is also held in the track circuit name column within the protection range. Further, if there is a route that is less than the contact limit from the route within the protection range, the route is held in the route name column below the contact limit.

If there are a plurality of routes arriving at the terminal route, they are numbered and all search results are held. If the terminal route cannot be reached, the unreachable route is output.

In the example of the route 1R shown in FIG. 2, the route 1R is held in the route name column of the route data 1061 of the route 1R,
From the route data 1042, the route 4T-1 holding the origin track circuit 4T is detected as the immediately preceding route, and the routes 9T-1 and 9T-2 holding the landing track circuit 9T are detected as the final routes. . Next, 5T-, which is an adjacent route of 4T-1,
The search is repeated until 9T-1 or 9T-2 is reached, such as 1, the adjacent route 10T-1, the adjacent routes 11T-1 and 11T-2. Finally, from the next of the immediately preceding path 4T-1, {5T-1,10T
A route of -1, 11T-2, 8T-1, 9T-1} is held in the route name column within the protection range as a route. Then, a track circuit including each path is searched using the path data 1042, and {5T, 10T, 11T, 8T, 9T}.
The track circuit is stored in the track circuit name column of the track data 1061 for track 1R. In addition, {6T-1} is used as a route that is less than the contact limit from each route.
Is held in the path name column below the contact limit.

Next, the name of the rolling device and the direction column for locking the course data 106 will be described below.

From the switch device data 1043, the localized route names and the inverted route names of all the switch devices are extracted, and the switch devices matching the route names held in the routes within the protection range are found. If so, including the direction, the turning device and its direction,
Hold it in the name and direction of the rolling device to be locked. In addition, if there are tactile devices that are controlled simultaneously,
Hold in the same direction.

In the example of the route 1R shown in FIG. 2, the route 5T-
There is no tipper holding 1 and in this case nothing is held. The turning device holding the path 10T-1 is {10, localization}, which is held. As a result of searching for all the routes stored in the route name, {1
0, localization} {11 a, localization} {11 b, localization} {9, localization} are stored in the column of route data 1061 of the route 1R in the column of transition devices.

Course data 10 created by the processing unit 105
6, the relationship information 108 of the route is generated by using the processing unit 107 described below. In this processing unit, binary paths are extracted from all the paths and compared for all combinations.

FIG. 9 shows an example of the contents of the course related information 108.

The track circuit name of the protection range of each track data corresponding to the binary path to be considered, the name of the rolling device to be locked, and the direction to be changed are extracted and both are used as the track circuit in the protection section. If there is a track circuit included in, the track circuit name field of the conflicting relationship information 108 is held. This information means that this track circuit is thus required by the binary path under consideration.

In the example of the route 1R and the route 2L shown in FIG.
The track circuits included in both track 1R and track 2L are {10
T, 11T}. This is held in the competing track circuit name column of the relationship information 1081 of the route 1R and the route 2L.

Further, the route name within the protection range and the route name less than the contact limit of each route data corresponding to the binary route are taken out, and one route less than the contact limit becomes the track circuit in the other protection range. If included, the track circuit including the route is also held in the competing track circuit name column.

This information means that there is a risk of contact on this path.

In the example of route 1R and route 2L shown in FIG.
The route {6T-1} that is less than the contact limit of the route 1R is the route 2
Since it is not included in the route within the protection range of L, the track circuit name column within the protection range is not added.

Next, if there is a rolling device included in both as the rolling device to be locked, it is held in the competing rolling device name column of the path relation information 108. This information is,
This means that the turning device is locked for the passage of trains and vehicles together with the binary path under consideration.

In the example of the route 1R and the route 2L shown in FIG.
The turning devices included in both the route 1R and the route 2L are {1
0, 11 a, 11 b}. This is track 1R and track 2
It is held in the competing rolling device name column of the L relationship information 1081.

However, if they are not on the competing track circuits and have the same direction of conversion, they are not competing and are not held. This means that even if both of the two paths under consideration are locking devices that must be locked for the passage of trains and vehicles, they are out of the protection range in one path, and the directions to be changed are both. If both are the same, it means that there is no risk of collision or contact accident even if the two paths are drawn at the same time, and therefore it is meant to be excluded from competing rolling devices. The turning device removed here is held together with the direction in the turning device / direction column which is not on the competing track circuit of the path relation information 108 and has the same turning direction. The binary path, which has no competing track circuits and is free of competing trollers by this operation, is specially called “parallel path” in the combination of “no competition”.

An example of the route 1R and the route 3L shown in FIG. 2 will be described. If you look at the wiring diagram and route diagram, you can see that there is no problem with safety even if you follow the route at the same time.
However, the tumbler included in both path 1R and path 3L,
There are {11 a, 11 b}. Rolling device data 104
In 3, the localization route of 11a is 11T-2 and the inversion route is 1
1T-1 with route data 10 of route 3L for both routes
From 63, it can be seen that it is not included in the route through which the train of route 3L passes. That is, 11a is outside the protection section of the route 3L. Similarly, 11b is also outside the protection section of the route 1R. Furthermore, the locking direction is normal for both 11a and 11b. Therefore, the relationship information 10 of the paths of the paths 1R and 3L
There are 82 competing orbital circuits, and the turning direction is the same for the turning direction, in the direction column {11 a, localization}
{11B, localization} is held.

As a result, there is no competing track circuit or competing point switch between path 1R and path 3L. The processing unit 107 also extracts the relationship between parallel paths such as the path 1R and the path 3L.

The above operation is repeated for each binary data set, and the competing track circuit name and competing switch device name are held for each set. These are the relationship information 108
Make up.

The relationship information 108 on the route generated by the processing unit 107 is output by using the processing unit 109 described below.

Regarding the binary path, the origin track circuit name and the destination track circuit name are extracted from the traffic light data 1044,
It is detected whether the starting track circuit and the ending track circuit of one course match the starting track circuit or the ending track circuit of the other route. Further, for this binary route, the competing track circuit names of the track relationship information 108 and the track circuit names within the protection range of the track data 106 are compared, and the track circuit names within the protection section for the binary track held in the track data 106 are compared. Among the track circuits, those which are track circuits in which the relationship information of the paths compete with each other are detected. Based on this detection result, the relationship between the binary paths is classified and output.

For example, if all are detected, it is output that it is contained in the other course, and only the track circuits in the middle of each other, that is, the track circuits that are neither the origin track circuit nor the landing track circuit are held. If so, it outputs that the binary paths intersect. Also, if the origin track circuits match,
The binary path has the same origin, there is no competing track circuit, there is no competing tracker, there is no competing track circuit, and there is a roller with the same direction to switch. Outputs that the binary paths are parallel paths.

In the example of the route 1R and the route 2L shown in FIG.
The origin track circuit is different between 4T and 15T, and the competing track circuits {10T, 11T} are neither the ending track circuit 9T of track 1R nor the ending track circuit 7T of track 2L. 109 outputs that the route 1R and the route 2L intersect.

In the example of the route 1R and the route 3L, there is no competing track circuit or competing rolling device, and there is no competing track circuit on the competing rolling circuit, and the rolling direction is the same. Since (11a, localization) {11b, localization} is held, the processing unit 109 outputs that the route 1R and the route 3L have a parallel route relationship.

In the case of the route 2L and the route 3L, since the origin track circuits of the route 2L and the route 3L are both 15T,
The processing unit 109 outputs that the starting points of the route 2L and the route 3L are the same.

As an example of the output, FIG. 10 shows an image in which the relationship information of the route is expressed in a battle table format. If the first row is the route 1R and the second column is the route 2L, a symbol indicating that the routes intersect at the first row and the second column is displayed.

Further, as a wiring diagram, equipment data 104
Is used to display all track circuits / routes / rollers in the range to be considered, and the track circuits / routes / rollers stored in the track data 106 for the relevant binary route are displayed on the wiring schematic diagram. 11 and 12 show an example in which the track circuit, the route, and the rolling device stored in the vessel-related information and the path-related information 108 are distinguished and output by color and thickness. Figure 11 shows the track circuit,
FIG. 12 is an output image focusing on the route. The double line shows a track circuit within the protection range of the route 1R in FIG. 11, and shows a route within the protection range of the route 1R in FIG. The drawing color is different from the drawing colors of the track circuit and the route.
A thick line shows a track circuit within the protection range of the route 2L in FIG. 11, and shows a route within the protection range of the route 2L in FIG.
The drawing color is different from the drawing colors of the track circuit, the route, and the route 1R.

(Effect of this embodiment) According to this embodiment, since the relationship information of the route is automatically output from the facility data, simplification of the work for the interlocking logic creator to recognize the relationship information of the route. -High speed can be achieved. In addition, it is possible to express the relationship information of the course in a battle table format or a wiring diagram,
This has the effect of enabling knowledge sharing between interlocking logic designers and facilitating communication of intentions.
