Description

  The present invention relates to a railway schematic diagram creating system for creating a railway schematic diagram.

  There is a schematic diagram of the track in drawings used for railway operations. The railway schematic diagram represents railway lines and railway equipment. In the schematic diagram of the track, the track is represented by a diagram that is deformed for easy viewing, and the railroad equipment is represented by a symbol corresponding to the application. There are many types of schematic diagrams depending on the application, for example, wiring schematic diagrams, signal display system diagrams, feeder system diagrams, and the like. The wiring schematic diagram represents a traffic signal or the like as railway equipment, and is used for operation and maintenance of operation equipment. The signal display system diagram shows a traffic signal, a ground element, a railroad crossing, etc. as railroad equipment, and is used for maintenance of the signal security equipment. The feeder system diagram shows feeder wiring, sections, substation connections, etc., and is used for command and maintenance of power facilities. Since the sections that can be displayed in one figure are limited, a large number of schematic diagrams are created for each type.

  Track schematics have been created by hand for many years. Users of track schematics are accustomed to seeing such conventional line schematics. The track schematics will need to be modified with changes in railway facilities. There are many types of track schematics, and there are many types of each type, so manual correction is not easy.

  Instead of manual work, an apparatus for automatically creating a schematic diagram based on the geographical information of the railway and railway facilities has been proposed (see, for example, Patent Document 1). However, since such a device automatically deforms the line alignment, the created line schematic does not match the familiar conventional line schematic, and is not necessarily easy to see for the user.

(First embodiment)
A schematic diagram creation system according to a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the schematic diagram creation system 1 includes a geographic coordinate information database 11, an input unit 12, a processing unit 13, and an output unit 14. The geographic coordinate information database 11 stores the geographic coordinates of railroad tracks and railway facilities. The input unit 12 receives data input. The processing unit 13 creates a schematic line diagram based on the data stored in the geographic coordinate information database 11 and the data input to the input unit 12. The output unit 14 outputs the schematic line diagram created by the processing unit 13.

  As shown in FIG. 2, the line R is divided into a plurality of line blocks B in the geographic coordinate information database 11 and the line schematic diagram 2. The line block B does not branch within the block. Each line block B is given a unique identification code (B1 to B22).

  As shown in FIG. 3, the geographic coordinate information database 11 further stores, for each railway facility S, an identification code (B13, etc.) of the track block B to which the railway facility S belongs.

  The input unit 12 is input with the diagram of the line block B shown in the schematic line diagram 2 and the identification codes (B1 to B22) of the line block B.

  The processing unit 13 refers to the geographic coordinate information database 11 using the identification codes (B1 to B22) input by the input unit 12, and extracts the railway equipment S belonging to each track block B. The processing unit 13 refers to the geographic coordinate information database 11 for each extracted railway facility S, and is a block that is a distance along the track center line from one end P in the track block B to which the railway facility S belongs. The distance DS is calculated.

  As shown in FIGS. 3 and 4, the processing unit 13 determines the position (LS) of the railroad equipment S on the schematic line of the railway, the block distance DS, the actual length DB of the line block B, and the line block B on the schematic line diagram. Is calculated based on the length LB.

  The processing unit 13 creates the line schematic diagram 2. The created schematic diagram 2 shows a diagram inputted by the input unit 12 and a railway facility S whose position on the schematic diagram is calculated by the processing unit 13. The line schematic diagram 2 created by the processing unit 13 is output by the output unit 14. In FIG. 2, illustration of some railway facilities S is omitted.

  Each configuration will be further described in detail (see FIG. 1). The geographic coordinates of the track stored in the geographic coordinate information database 11 are the geodetic coordinates of the track center line, that is, the latitude and longitude of the track center line. The geographical coordinates of the railway equipment are the latitude and longitude of the railway equipment. In this embodiment, a part of the data in the database created for the electronic line plan view system, which is another system, is used for the geographic coordinate information database 11 of the line schematic drawing system 1. The electronic track plan view system is a system that displays tracks, railroad facilities, and the like on an electronic map, and has recently been introduced. The geographic coordinate information database 11 may be provided exclusively for the track schematic drawing system 1 or shared with the electronic track plan view system.

  The input unit 12 includes a human interface such as a keyboard and a mouse that receives data input by a user operation, and an input interface that receives data input of an electronic file. The processing unit 13 includes a memory that stores a program for data processing, a CPU that executes the program, and the like. The output unit 14 includes a display and the like. The output unit 14 may include a printer.

  The line block B will be described in detail (see FIGS. 3 and 4). Since the line block B does not branch within the block, the end P of the line block B is located at a node in the diagram representing the line R. The diagram representing the track R is the track center line of the track in the map or the track R in the track schematic diagram 2, and is a graph in graph theory. A node is a term in graph theory and is located at a branching unit or a line termination. A branching device is provided at a branching point of a railway. As shown in FIG. 5, the position of the branching device is the front end PF of the branching device. Thereby, the reference | standard of the position in the track block B becomes still clearer. The line end is a dead end of the line (not shown). In the schematic line drawing system 1, the boundary between the system introduction section and the non-introduction section, that is, the end of the line on the data is also treated as a node.

  For example, in the schematic line diagram 2 shown in FIG. 2, the line block B is given a unique identification code from B1 to B22. There are two lines R between the branching device P1 and the branching device P2 adjacent to the branching device P1 in the line direction. Each of the lines R is a line block B, and identification codes B13 and B14 of the line block B are given. In the geographic coordinate information database 11 and the schematic line diagram 2, the same line block B is assigned a common identification code, and is associated with the identification code as a key. The identification code given to the line block B is called a line block ID.

  The position of the railway equipment S is specified by the track block B and the block distance DS to which the railway equipment S belongs. For example, in FIG. 3, the block distance DS is a distance from one branching device P <b> 1 in the line block B. The end of the line block B that serves as a reference for the block distance DS is referred to as a starting end P1, and the other end is referred to as a terminating end P2. The starting end P1 of the line block B is generally the end P on the starting point side of the line R, although there are exceptions. The starting point is set for each section. For example, the starting point of the Tokaido Main Line is Tokyo Station. The processing unit 13 calculates the block distance DS of the railway equipment S based on the geographic coordinates of the intersection of the perpendicular line from the railway equipment S to the track center line of the track block B to which it belongs and the track center line, and the geographic coordinates of the starting end P1. To do.

  In the schematic line 2 of FIG. 2, the line block B is illustrated by a line, and since there are a start end P1 and a terminal end P2, it may be illustrated by an arrow from the start end P1 to the terminal end P2 (see FIG. 4).

  Each line block B is uniquely identified by a line block ID. Since the position of the railway facility S is specified by the track block ID and the block distance DS, the combination of the track block ID and the block distance DS is referred to as track block coordinates. Not only the railway equipment S but also an arbitrary position on the track is specified by the track block coordinates.

  The position of the railway facility S directly specified by the track block coordinates is a relative position from the start end P1 of the track block B. Since the starting end P <b> 1 of the track block B is on the track R, the geographical coordinates thereof are included in the geographical coordinates of the track R and are stored in the geographic coordinate information database 11. Therefore, the absolute position of the railway facility S is specified by the geographical coordinates of the starting point P1 stored in the geographical coordinate information database 11 and the track block coordinates.

  Conventionally, about a kilometer has been used as the position of the railway equipment S in the railway. However, for example, in the schematic line 2 shown in FIG. 2, the traffic light 2L and the traffic light 3L are about the same kilometer, and therefore the positions cannot be distinguished by the kilometer.

  On the other hand, by using the track block coordinates (track block ID, block distance DS), the position of the railroad equipment S is distinguished even if the kilometer is the same. For example, the line block coordinates of the traffic light 2L are (B13, 126m) when the block distance DS is 126m. The line block coordinates of the traffic light 3L are (B14, 125m) when the block distance DS is 125m. Such a concept of track block coordinates was created by the present inventors.

  The creation of the schematic diagram 2 in the schematic diagram creation system 1 configured as described above will be described in detail. The diagram of the track R shown in the schematic diagram 2 and the identification code (track block ID) of the track block B are input from the input unit 12 as an electronic file. The electronic file uses a CAD data format or a similar data format. In the electronic file, it is desirable that the shape and position of the diagram on the schematic diagram of the line are substantially the same as those of the conventional familiar schematic diagram.

  Further, the type of railway equipment S shown in the schematic diagram 2 is input from the input unit 12. The type of railway equipment S is, for example, a traffic light. In this embodiment, the types of selectable railway facilities S are displayed on the display as the output unit 14, and the types of the railroad facilities S shown in the schematic diagram 2 are selected by the mouse as the input unit 12. By inputting the type of the schematic diagram to be created to the input unit 12, the type of the railway equipment S represented in the type of schematic diagram of the track may be automatically input. For example, when the type of railway schematic to be created is a wiring schematic, the type of railway equipment S is a traffic light or the like. In addition, the input of the type of railway equipment S may be omitted, and all types of railway equipment S may be configured as shown in the schematic diagram 2 of the track.

  The processing unit 13 refers to the geographic coordinate information database 11 using the identification code (track block ID) of the track block B input by the input unit 12, and for each type of the rail facility S input, each track block B The railway equipment S belonging to is extracted.

  When the distance from the starting end P1 in the track block B to which the railway equipment S belongs is DS, the actual length of the track block B is DB, and the length of the track block on the schematic diagram of the track 13 is LB, The distance LS from the starting end P1 on the line schematic diagram 2 is calculated by proportional calculation as shown in the following equation (see FIGS. 3 and 4).

  LS = (DS / DB) × LB

  Here, the actual length DB of the track block B is calculated by the processing unit 13 based on the geographic coordinates of the track R stored in the geographic coordinate information database 11. The length LB of the line block B on the schematic line diagram is calculated by the processing unit 13 based on the diagram input from the input unit 12.

  The starting end P1 of the track block B on the track schematic 2 is specified by a diagram representing the track R inputted from the input unit 12, and the position of the railroad equipment S on the track schematic 2 is calculated based on the above proportional calculation. Is done. In the present embodiment, the length LB of the line block B on the schematic line diagram and the distance LS from the start end P1 are values along the diagram representing the line R.

  The railway equipment S is represented by a symbol on the schematic diagram 2. Based on the calculated position of the railroad equipment S on the railroad schematic diagram, the processing unit 13 creates the railroad schematic diagram 2 in which the symbols of the railroad equipment S are arranged. The symbol of the railway facility S is arranged on the track in FIG. 2, but may be arranged so as not to overlap the track.

  The symbol of the railway facility S is stored in the memory of the processing unit 13. The symbol of the railway facility S may be stored in the geographic coordinate information database 11. When the railway equipment S is oriented like a traffic light, information on the orientation of each railway equipment S is stored in the geographic coordinate information database 11.

  Moreover, in the track schematic diagram 2, the railway equipment S represents the name (2L, 3L, etc.) of the railway equipment S together with a symbol (see FIG. 2). The names of the railway facilities S are stored in the geographic coordinate information database 11.

  The processing unit 13 may further display the block distance DS of the railroad equipment S in the schematic line diagram 2.

  The block distance DS is a distance from the starting end P1 of the line block B, and the measurement of the distance is easier than the measurement of geographic coordinates. In addition, the starting end P1 of the line block B, which serves as a reference for the block distance DS, is a branching device or the like, and can be easily visually recognized at the site. For this reason, by using the track block coordinates, it becomes easier for the user to specify the position of the railway facility S than to directly use the geographical coordinates.

  As described above, according to the line schematic diagram creating system 1 according to the present embodiment, since the diagram of the line block B represented in the line schematic diagram 2 is input, the shape of the diagram is not automatically deformed by the system. An easy-to-see track schematic diagram 2 can be created. Moreover, since the process part 13 extracts the railroad equipment S which belongs to each track block B, and calculates the position on the track schematic of each extracted railroad equipment S, the track schematic 2 can be created easily.

  The position information of the train T is input to the processing unit 13 from a system capable of grasping the position of the train T, for example, an operation management system. The position of the train T is represented by track block coordinates.

  As FIG. 7 shows, the process part 13 calculates the position on the track schematic of the train T similarly to the position on the track schematic of the railway equipment S. As shown in FIG. That is, the processing unit 13 sets the position (LT) of the train T on the schematic diagram of the train T, the distance from one end (starting end) of the track block B on which the train T travels, the actual length of the track block, and the track. Calculation is based on the length LB of the line block B on the schematic diagram. The processing unit 13 outputs the created schematic diagram of the track and the position of the train T on the schematic diagram of the train T to the output unit 14.
