Abstract

PROBLEM TO BE SOLVED: To provide a method and an apparatus for three-dimensionally displaying a train position that enable train positions to be displayed three-dimensionally by relating a position of a two- or more formation train with time.SOLUTION: Two-dimensional information of a train position at a plurality of determined times is acquired from a wiring diagram, a linkage table, and a train position operation pattern to obtain values from respective reference points. A three-dimensional coordinate space where the x axis and y axis indicative of two-dimensional coordinates and the time base indicative of time are coordinate axes, respectively, is plotted with values from reference points as three-dimensional coordinate values, so that a display image of train positions where plotted points are time-sequentially connected is generated and displayed on the screen of a display device.

Description

  The present invention relates to a three-dimensional train position display method and apparatus for three-dimensionally displaying a train position on a screen of a display device.

In the field of railway signals, when developing functions of interlocking devices that control traffic lights and turning machines, in order to verify the safety and validity of the developed functions, various train operation patterns are applied to these functions. I was considering it.
Specifically, a timing diagram that displays changes in a plurality of control signals and the like on the time axis and a drawing that displays the corresponding train position information in correspondence with each other, using the drawing that displays the corresponding train position information and the control signal, etc. By grasping the relationship, the safety and validity of the developed function were verified.
For example, in the function of operating a railroad crossing alarm, a railroad crossing alarm is activated when the detection signal a of the sensor A that detects the approach of the train to the railroad crossing is output, and then the train has passed the railroad crossing. It is made to function so that the crossing warning is stopped when the detection signal b of the sensor B that detects the above is output.

At this time, the drawings for verifying the function are the detection signal a of the sensor A that detects the approach of the train to the level crossing, the detection signal b of the sensor B that detects that the train has passed the level crossing, and an alarm signal. FIG. 20 shows a control signal c that activates the control signal c displayed on the time axis.
From such a drawing, at the time when the detection signal a of the sensor A and the detection signal b of the sensor B are output, it can be recognized that the train exists at the installation position of the sensor, and the position of the train and the control signal c By grasping the relationship, it is possible to verify the safety and validity of the developed function.
Further, an apparatus for simulating the operation of a signal control connection diagram using a railroad signal line diagram and a signal control connection diagram created on a CAD screen is disclosed (for example, see Patent Document 1).

However, when a timing diagram in which changes in a plurality of control signals are displayed on the time axis is used, there is no problem in verifying that only one train operates, but two or more trains operate. When trying to verify the case, the relationship between the train position and the control signal cannot be easily recognized.
That is, when the subsequent train passes the sensor A before the preceding train passes the sensor B, the detection signal b is 2 after the detection signal a is output twice on the time axis. Will be output once. However, since there is no information on the train position on the time axis, it is impossible to determine which detection signal corresponds to which train from the timing diagram alone. There was a problem that the relationship between position and time could not be easily recognized.
Further, even the prior art of Patent Document 1 does not assume a case where two or more trains are operated, and the relationship between the train position and the time cannot be easily recognized.

[1. Description of configuration]
Hereinafter, a three-dimensional train position display method and apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(First embodiment)
The structure of the apparatus using the three-dimensional train position display method of 1st Embodiment of this invention is demonstrated with reference to FIG. FIG. 1 is a schematic configuration diagram illustrating a function of the apparatus 100 using the three-dimensional train position display method as a block diagram.

A processing result integration unit 5 and a display unit 6 are provided.
The functions of the three-dimensional space configuration unit 3, the interlocking device function unit 4, and the processing result integration unit 5 are realized by the arithmetic control unit 50. Specifically, the arithmetic control means 50 has a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and is stored in a ROM or the like developed in the RAM work area. The input operation unit 1, the storage unit 2, and the display unit 6 are collectively controlled by the cooperation of the various program data and the CPU, and at the three-dimensional space configuration unit 3, the interlocking device function unit 4, and the processing result integration unit 5.

For example, the storage unit 2 is an HDD (hard disk drive), an SSD (solid state drive), a semiconductor memory, etc., and includes information such as a wiring diagram, an interlocking table, and a train operation pattern acquired by the input operation unit 1 in advance. Information such as the captured wiring diagram, linkage table, and train operation pattern is stored.

[2. Explanation of 3D train position display operation]
Here, the description of the specific operation of the apparatus using the three-dimensional train position display method in the first embodiment of the present invention will be described with reference to FIGS. 2, 3, 4, 5, 6, 7 and 8. Use in detail.
As shown in the flowchart of FIG. 2, the input operation unit 1 acquires a wiring schematic input from the outside of the apparatus 100 under the control of the arithmetic control unit 50 (step S <b> 1). Further, the input operation unit 1 acquires an interlocking table input from the outside of the apparatus 100 under the control of the arithmetic control unit 50 (step S2). Furthermore, the input operation part 1 acquires the train operation pattern input from the exterior of the apparatus 100 by control of the calculation control means 50 (step S3).

  And the three-dimensional space structure part 3 is an axis | shaft which extracts the position (x, y) of the train in the predetermined time (t) from the acquired wiring schematic, an interlocking | linkage table, and a train operation pattern, and shows a two-dimensional coordinate. The extracted three-dimensional coordinate values are sequentially plotted in a three-dimensional coordinate space in which the x-axis and y-axis and the t-axis that is the time axis are arranged in three dimensions, and the processing results are obtained by connecting the plot points in time series. It outputs to the integration part 5, and outputs a train operation pattern to the interlock device function part 4 (step S4).

Here, the processing content of the three-dimensional space configuration unit 3 will be described in more detail.
Fig.3 (a) is an example of the wiring schematic diagram which showed the connection of a track | line using the straight line and the symbol, and FIG.3 (b) was attached to the turning machine and signal apparatus which ensure a specific path | route. It is an example of an interlocking table in which a name, a number, a lock, etc. are described. FIG. 4 is an example of a train operation pattern (so-called diagram) in which the time is plotted on the horizontal axis, the distance is plotted on the vertical axis, and the station name is placed on the vertical axis.

The three-dimensional space configuration unit 3 extracts the arrangement information of the equipment such as the switch and the traffic light at the station, the position information of the platform and the arrival departure lane number, and the like from the acquired wiring schematic. For example, from the schematic wiring diagram shown in FIG. 3A, “B station” is located between “A station” and “C station”, and the arrival departure line numbers from line 1 to line 3 are displayed on the platform. The position information is extracted such that the second line, which is a reserve line, is located between the first line and the third line.
In addition, “B” station has eight on-site traffic lights “1R” to “8L” or departure traffic lights, and “11”, “12”, “13”, “21”, “22” and The arrangement information of the equipment such as “23” of the six turning machines is arranged. However, time information cannot be extracted from the acquired wiring schematic.

  In addition, the three-dimensional space configuration unit 3 extracts names and numbers given to the turning machines and traffic lights that secure a specific route in the station area from the acquired linkage table. For example, from the linkage table shown in FIG. 3B, in order to enter the second line from “A station direction”, it is necessary that the traffic signal “2R” indicates the progress indication, etc. It is extracted that it is necessary for the departure traffic light “4R” to have a progress indication or the like in order to proceed to the main line of “C station direction”. However, time information cannot be extracted from the acquired linkage table.

  Further, the three-dimensional space configuration unit 3 extracts the arrival time at the station where each train is located, the departure time from the station, and the arrival departure lane number from the acquired train operation pattern. For example, from the train operation pattern shown in FIG. 4, the ID41 train arrives at the B station 2 line at time t = 3, and then the ID 42 train passes the B station line 1 between the times t = 3 and 4. Waiting to pass, it is extracted that the vehicle departs from the second line toward station C at time t = 4. However, train position information and arrangement information at station B cannot be extracted from the acquired train operation pattern.

  That is, it is impossible to extract time information, position information, and arrangement information from only one information of a wiring schematic, a linkage table, or a train operation pattern, so that it is possible to obtain a three-dimensional coordinate value. It will not be possible.

  For this reason, the three-dimensional space configuration unit 3 combines the information extracted from the acquired wiring schematic, the interlocking table, and the train operation pattern, so that, for example, the train of ID41 is in-field signal from the main line at time t = 1-3. With the progress indication of “2R”, enter the second stop line of B station, stop at the B station No. 2 until time t = 3-4, and then follow the progress indication of the departure signal “4R” At time t = 4 to 6, the two-dimensional position information (x, y) at a predetermined time (t), such as traveling from the second line to the main line “C station direction” and heading to the C station, is time-sequentially. Can be obtained. That is, a three-dimensional coordinate value (x, y, t) can be extracted.

Finally, the three-dimensional space configuration unit 3 plots the extracted three-dimensional coordinate values (x, y, t) on the three-dimensional coordinate space, and connects the plotted points in time series. For example, as shown in FIG. 5, a schematic diagram of the station B wiring (in FIG. 5, description of facility arrangement information and the like is omitted) is displayed on the xy axis plane that is position information, and the preceding ID 41 The train position and the time are associated with each other and the train position is displayed in three dimensions. Similarly, the train position is displayed in three dimensions by associating the position of the train of the subsequent ID 42 and the time.
As can be seen from the three-dimensional train position display image in FIG. 5, the train with the preceding ID 41 stops at the second line of the B station at the time t = 3 to 4, while the train with the subsequent ID 42 is in the B station. No. 1 line passes, so the coordinates of the two trains do not intersect (collision).

  Returning to the flowchart of FIG. 2, the interlock device function unit 4 generates a control signal or the like by simulating the function of the interlock device based on the input train operation pattern, and sets the control signal or the like to the t-axis indicating the time. The displayed timing diagram is created and output to the processing result integration unit 5 (step S5). For example, as shown in FIG. 6, a timing diagram in which three signals as shown in SG <b> 61 to SG <b> 63 are displayed on the time axis is created and output to the processing result integration unit 5.

Then, the processing result integration unit 5 integrates the three-dimensional train position display image input from the three-dimensional space configuration unit 3 and the timing diagram input from the interlock device function unit 4 to display the display screen of the display unit 6. Is displayed (step S6).
For example, as shown in FIG. 7, an image in which a three-dimensional train position display image and a timing diagram are integrated on the time axis is displayed on the display unit 6. For this reason, it is possible to simultaneously grasp the train position for each time of the plurality of trains and the change status of the plurality of signals related to the train position.

  Finally, the processing result integration unit 5 determines whether or not to end the process by the screen operation of the input operation unit 1 under the control of the arithmetic control unit 50 (step S7). (Step S7: Yes), the process ends. On the other hand, when it is determined that the process is not ended (step S7: No), a process for editing the train operation pattern is performed by the screen operation of the input operation unit 1 (step S9), and the process returns to step S4.

For example, as an acquired train operation pattern, a train with ID81 enters the second line from station A to station B at time t = 1 to 3, whereas a train with ID82 has time t = 1 to 3, a case is assumed where the train operation pattern is such that the train enters from the C station direction to the second line of the B station.
When the three-dimensional train position display is performed using such a train operation pattern, for example, 3 coordinates of two trains (ID81 and ID82) in the coordinate CD81 as in the three-dimensional train position display image shown in FIG. It can be seen that the dimensional coordinate values intersect and the trains collide.
Accordingly, since the operator who performs the verification can recognize that there is a serious problem in the train operation pattern, the train operation pattern is appropriately edited and the three-dimensional train position display is performed again in step S9. Thus, it can be confirmed that there is no problem such as collision between trains. That is, it is possible to confirm a difference in understanding by an operator or the like and a train operation pattern leakage at the time of verification, and to prevent the problem from occurring.

As described above, the train position (x, y) at a predetermined time (t) is obtained from the wiring schematic diagram, the interlocking table, and the train operation pattern, and the three-dimensional coordinate value (x, y, t) is extracted. The extracted three-dimensional coordinate values are plotted and connected in time series in a three-dimensional coordinate space in which the x-axis and y-axis, which are two-dimensional coordinates, and the t-axis indicating time are arranged in three dimensions. By displaying the three-dimensional train position image, it is possible to display the train position in three dimensions by associating the position of two or more trains with the time, so that each individual can understand when verifying functions related to train operation. Differences and train operation pattern leakage can be prevented.
In addition, since the train position display image and the timing diagram can be compared by displaying the three-dimensional train position display image and the timing diagram in an integrated manner, the train position for each time of a plurality of trains, It is possible to grasp a change state of a plurality of signals related to the train position.

On the other hand, by directly operating the train position in the three-dimensional coordinate space and changing the coordinate point, a new train operation pattern is extracted from the changed coordinate point, and the control signal is obtained by simulating the function of the interlocking device. It is also possible to create a timing diagram by generating the like and change the state of the created timing diagram.
Here, the simulation operation of the interlocking device function will be described in detail with reference to FIGS. Of steps in the flowchart shown in FIG. 9, steps S11 to S16 are the same as steps S1 to S6 shown in FIG.

As shown in the flowchart of FIG. 9, the three-dimensional space configuration unit 3 is configured to display integrated information displayed on the display screen of the display unit 6 by a screen operation based on a command signal from the input operation unit 1 under the control of the arithmetic control unit 50. Among these, it is determined whether or not the coordinate value of the train displayed in the three-dimensional coordinate space has been changed (step S17).
If the three-dimensional space configuration unit 3 determines that the coordinate value of the train displayed in the three-dimensional coordinate space has been changed (step S17: Yes), the changed three-dimensional coordinate value (x, y, t). The train operation pattern is extracted from the above information and input to the interlocking device function unit 4 (step S18), and the process returns to step S15. On the other hand, when it is determined that there is no change in the coordinate value (step S17: No), the process is terminated.

In step S15, the interlocking device function unit 4 simulates the function of the interlocking device based on the newly extracted train operation pattern, generates a control signal, etc., newly creates a timing diagram, and integrates the processing results. Then, the processing result integration unit 5 replaces the previous timing diagram with a new timing diagram input from the interlocking device function unit 4 and displays the timing diagram on the display screen of the display unit 6. (Step S16).
For example, in the three-dimensional train position display of FIG. 10, the coordinates of the train of ID 101 displayed in the three-dimensional coordinate space by a screen operation by a command signal from the input operation unit 1 (for example, a pointing device) under the control of the arithmetic control unit 50. Assume that the point is changed as indicated by a broken line SM101. In this case, in the interlocking device function unit 4, the waveform of the signal of the timing diagram shown in FIG. 10 generated by simulating the function of the interlocking device is obtained from the information of the changed three-dimensional coordinate values (x, y, t). Based on the extracted train operation pattern, for example, as shown in SG101 to SG103, it changes.

  As described above, when a coordinate point is changed by directly operating the train position in the three-dimensional coordinate space on the screen, a new train operation pattern is extracted from the changed coordinate point and controlled by simulating the function of the interlocking device. By creating a timing diagram by generating signals, etc., the state of the created timing diagram can be changed, so it is possible to intuitively change the train operation pattern and simulate the function of the interlocking device It is possible to prevent differences in understanding among individuals and leakage of train operation patterns when verifying functions related to train operation.

[4. Explanation of xy axis plane display operation]
It is also possible to designate a specific time and display the position information of the train on the xy axis plane at the specific time.
Here, the operation of displaying the position information of the train on the xy axis plane at a specific time will be described in detail with reference to FIGS. 11 and 12. Of the steps in the flowchart shown in FIG. 11, steps S21 to S26 are the same as steps S1 to S6 shown in FIG.

As shown in the flowchart of FIG. 11, the processing result integration unit 5 determines whether or not a specific time is designated by the screen operation of the input operation unit 1 under the control of the arithmetic control unit 50 (step S <b> 27).
If the processing result integration unit 5 determines that a specific time has been designated (step S27: Yes), the displayed three-dimensional train position display image is switched to the xy axis plane display (step S28). ), The process returns to step S26. On the other hand, if it is determined that there is no time designation (step S27: No), the process is terminated.
In step S26, the processing result integration unit 5 displays the train position at the specified specific time on the xy axis plane (step S26).

For example, in the timing diagram of FIG. 12, the time axis cursor CR121 in the timing diagram is moved to time t = 3 by a pointing device operation or the like by the screen operation of the input operation unit 1 under the control of the arithmetic control means 50. When a specific time is specified, the three-dimensional train position display image is switched to the xy axis plane, and the train position at the time is indicated on the xy axis plane of FIG. (Stopped on line 2 of station B) is displayed.
Also, for example, in the timing diagram of FIG. 12, if the time axis cursor CR121 in the timing diagram is sequentially moved by the screen operation of the input operation unit 1 under the control of the arithmetic control means 50, the xy axis plane of FIG. Above, the train position is displayed according to the time of travel.

  As described above, the train position at the specific time can be cut out by specifying the specific time and displaying the position information of the train on the xy axis plane at the specific time. It is possible to prevent differences in understanding among individuals and leakage patterns of train operations when verifying functions and the like.

(Second Embodiment)
[5. Description of configuration]
The structure of the apparatus using the three-dimensional train position display method of 2nd Embodiment of this invention is demonstrated with reference to FIG. FIG. 13 is a schematic configuration diagram showing the function of the device 200 using the three-dimensional train position display method as a block diagram. However, the description similar to 1st Embodiment is abbreviate | omitted.
As shown in FIG. 13, an apparatus 200 using a three-dimensional train position display method (hereinafter simply referred to as an apparatus 200) includes an input operation unit 1, a storage unit 2, a three-dimensional space configuration unit 7, and a crossing control function unit. 8. A processing result integration unit 5 and a display unit 6 are provided.
The functions of the three-dimensional space forming unit 7, the level crossing control function unit 8, and the processing result integration unit 5 are realized by the calculation control unit 51. Specifically, the arithmetic control means 51 has a CPU, a ROM, a RAM, etc., and an input operation is performed in cooperation with various program data stored in the ROM and the like developed in the work area of the RAM and the CPU. The unit 1, the storage unit 2, and the display unit 6 are controlled in an integrated manner, and the processes of the three-dimensional space configuration unit 7, the crossing control function unit 8, and the processing result integration unit 5 are executed to realize the functions of the units.

  The three-dimensional space configuration unit 7 configures a three-dimensional coordinate space with the x-axis and y-axis, which are axes indicating a two-dimensional position, and the t-axis indicating time, as coordinate axes, and is input or stored in advance. The train position (x, y) at a predetermined time (t) is extracted from the wiring schematic diagram, railroad crossing control table, and train operation pattern, in other words, the three-dimensional coordinate value is extracted, and the extracted three-dimensional coordinate The values are sequentially plotted in the three-dimensional coordinate space, the plot points are connected, and output to the processing result integration unit 5. In addition, the three-dimensional space configuration unit 7 outputs the level crossing control table and the train operation pattern to the level crossing control function unit 8.

The level crossing control function unit 8 realizes the function of the level crossing control device, and includes the conditions for starting the ringing and the conditions for stopping the ringing described in the level crossing control table input from the three-dimensional space forming unit 7. Based on the information required for level crossing control and train operation patterns, the function of the level crossing control device is simulated to generate a control signal, etc., and a timing diagram is generated in which the control signal is displayed on the t-axis indicating the time. The result is output to the processing result integration unit 5. Further, the crossing control function unit 8 generates traffic signal display information and the like for simulating the function of the crossing control device as necessary.
The processing result integration unit 5 integrates the train time and two-dimensional position information plotted in the three-dimensional space input from the three-dimensional space configuration unit 7 and the timing diagram input from the crossing control function unit 8. And displayed on the display screen of the display unit 6.

[6. Explanation of 3D train position display operation]
Here, the specific operation of the apparatus using the three-dimensional train position display method according to the second embodiment of the present invention will be described with reference to FIGS. 13, 14, 15, 16, 17, 18 and 19. Use in detail. However, the description similar to 1st Embodiment is abbreviate | omitted.
As illustrated in the flowchart of FIG. 13, the input operation unit 1 acquires a wiring schematic input from the outside of the apparatus 200 under the control of the arithmetic control unit 51 (step S <b> 31). Further, the input operation unit 1 acquires a crossing control table input from the outside of the apparatus 200 under the control of the arithmetic control means 51 (step S32). Furthermore, the input operation part 1 acquires the train operation pattern input from the exterior of the apparatus 200 by control of the calculation control means 51 (step S33).

  Then, the three-dimensional space constituting unit 7 extracts the train position (x, y) at a predetermined time (t) from the acquired wiring schematic diagram, railroad crossing control table, and train operation pattern, and is an axis indicating two-dimensional coordinates. Plot the extracted three-dimensional coordinate values in a three-dimensional coordinate space in which a certain x-axis and y-axis and the t-axis, which is the time axis, are arranged in three dimensions, and connect the plotted points in time series for processing. It outputs to the result integration part 5, and outputs a level crossing control table and a train operation pattern to the level crossing control function part 8 (step S34).

Here, the processing content of the three-dimensional space formation part 7 is demonstrated in detail.
FIG. 15A is an example of a schematic wiring diagram showing the connection between tracks using straight lines and symbols, and FIG. 15B is a level crossing control such as a condition for starting a ringing and a condition for stopping a ringing. It is an example of a level crossing control table in which necessary information and the like are described. FIG. 16 is an example of a train operation pattern (so-called diagram) expressed in a graph form in which time is plotted on the horizontal axis, distance is plotted on the vertical axis, and X crossings and stations are arranged on the vertical axis.

The three-dimensional space constructing unit 7 obtains X crossing arrangement information, crossing control elements A and B arrangement information, arrangement information of switchboards and traffic lights at the station, platform and arrival departure line number from the acquired wiring schematic. The position information etc. are extracted. For example, from the schematic wiring diagram shown in FIG. 15A, “station” is located between “XX direction” and “△△ direction”, and the departure departure line number from line 1 to line 2 is on the platform. Position information such as
Also, there is an “X railroad crossing” between “station” and “XX direction”, and the “X crossing” of “X railroad crossing” is a “crossing control A” of the closed circuit type. Position information is extracted in such a manner that an open circuit type “crossing control B” is arranged in “X Δ crossing” of “X crossing”.
Also, from the acquired wiring schematic diagram, four traffic lights “2R”, “2L”, “3R” and “3L” are arranged, and “2LT”, “11T”, “2RT”, “3RT” and “12T”. The arrangement information of the facility such that the five track circuits are arranged is extracted. However, time information cannot be extracted from the acquired wiring schematic.

In addition, the three-dimensional space configuration unit 7 extracts information necessary for level crossing control at “X level crossing” from the acquired level crossing control table. For example, from the level crossing control table shown in FIG. 15 (b), when the train progresses from "XX direction" to "X level crossing", when a train is detected by "level crossing controller A", an alarm starts sounding and "level crossing" When the train is detected by the controller B, the alarm ends. When the train proceeds from the “△△ direction” to the “X railroad crossing”, the train is detected by the “track circuit (3RT)” and “ When the traffic light 2L is indicating the progress, the alarm starts to sound, and when the train is detected by the “crossing control B”, it is extracted that the alarm has ended. However, time information cannot be extracted from the acquired level crossing control table.
By the way, in the latter level crossing control, when a train is detected only by the “track circuit (3RT)” and the alarm is started, the alarm is always issued while the train stops at the second line of the station. It rings and becomes a so-called “crossing without opening”. For this reason, when the “traffic light 2L”, which is the starting traffic signal, shows a progress indication, the alarm is started to prevent “crossing without opening”.

Furthermore, the three-dimensional space configuration unit 7 uses the acquired train operation pattern to arrive at a station where each train is located, departure time from the station, arrival departure lane number, “X railroad crossing”, “railroad crossing controller A” and The passing time of “crossing control B” is extracted.
For example, from the train operation pattern shown in FIG. 16, the train of ID 161 arrives at the second line of the station from “△△ direction” at time t = 1, and then reaches the second line of the station between time t = 1 to 4. It is extracted that the vehicle stops and departs from the second line toward “X direction” between time t = 4 and time t = 5. However, it is not possible to extract train position information and arrangement information at the station from the acquired train operation pattern.

  That is, the time information and the position information and the arrangement information cannot be extracted at once from only one information of the wiring schematic diagram, the level crossing control table, or the train operation pattern, so that a three-dimensional coordinate value is obtained. It will not be possible.

  For this reason, the three-dimensional space configuration unit 7 combines the information extracted from the acquired wiring schematic diagram, railroad crossing control table, and train operation pattern, so that, for example, the train of ID 161 is a signal from the main line at time t = 0-1. With the progress indication of “3L”, the train enters the second line of the station, and stops at the second line of the station from time t = 1 to 4, and then the time t = 4 to 6 with the progress indication of the traffic light “2L” , Two-dimensional position information (x, y) at a predetermined time (t), such as going from the second line to the main line “XX direction” and heading toward “XX direction”, can be obtained in time series. . That is, a three-dimensional coordinate value (x, y, t) can be extracted.

Finally, the three-dimensional space configuration unit 7 plots the extracted three-dimensional coordinate values (x, y, t) on the three-dimensional coordinate space, and connects the plotted points in time series. For example, as shown in FIG. 17, a schematic diagram of wiring such as a station and an X crossing is displayed on the xy axis plane which is position information (in FIG. 17, description of facility arrangement information etc. is partially omitted). Then, the position of the train with the ID 161 ascending is associated with the time, and the train position is displayed in three dimensions. Similarly, the train position is displayed in three dimensions by associating the position and the time of the train with the ID 162 of the downlink.
As can be seen from the three-dimensional train position display image in FIG. 17, the train with the upstream ID 161 stops at the second line of the station at time t = 1 to 4 and the train with the downstream ID 162 becomes the first line of the station. Since we are waiting to enter the line, the coordinates of the two trains will not intersect (collision).

  Returning to the flowchart of FIG. 14, the level crossing control function unit 8 generates traffic signal display information and the like for simulating the function of the level crossing control device, and at the level crossing based on the input level crossing control table and train operation pattern. A control signal or the like is generated by simulating the function of the control device, and a timing diagram in which the control signal or the like is displayed on the t-axis indicating time is created and output to the processing result integration unit 5 (step S35). For example, as shown in FIG. 18, a timing diagram in which five signals as shown in SG 181 to SG 185 are displayed on the time axis is created and output to the processing result integration unit 5.

For example, in the timing chart shown in FIG. 18, when the “crossing controller A” detects a train of ID162 in DS181, the crossing warning control SG185 starts an alarm, and “crossing controller B” is ID162 in DS182. When the train is detected, it can be seen that the railroad crossing warning control SG185 ends the warning.
Further, for example, in the timing diagram shown in FIG. 18, “track circuit (3RT)” detects the second line of the ID 161 train at DS183, and “signal 2L” becomes “progress indication” at DS184. When the train is switched, the railroad crossing warning control SG185 starts an alarm, and when the “railroad crossing control element B” detects the train of ID161 in DS185, it can be seen that the railroad crossing warning control SG185 ends the warning.

  Incidentally, in the schematic wiring diagram shown in FIG. 15A, when the train travels in the “XX direction”, the “crossing controller B” is arranged in front of the “X crossing”, but the crossing warning control SG185 is Since the rear end of the train passes through the detection range of “railway crossing controller B”, it will stand up after a predetermined time has passed (alarm unlocking), so the alarm will stop sounding before the train passes the railroad crossing. There is no end to it.

Then, the processing result integration unit 5 integrates the three-dimensional train position display image input from the three-dimensional space configuration unit 7 and the timing diagram input from the crossing control function unit 8 to display the display screen of the display unit 6. The integrated information is displayed (step S36).
For example, as shown in FIG. 19, an image in which a three-dimensional train position display image and a timing diagram are integrated on the time axis is displayed on the display unit 6. For this reason, it is possible to simultaneously grasp the train position for each time of the plurality of trains and the change status of the plurality of signals related to the train position.

  Finally, the processing result integration unit 5 determines whether or not to end the process by the screen operation of the input operation unit 1 under the control of the arithmetic control unit 51 (step S37). (Step S37: Yes), the process ends. On the other hand, when it is determined that the process is not to be ended (step S37: No), the train operation pattern is edited by the screen operation of the input operation unit 1 (step S39), and the process returns to step S34.

As described above, the train position (x, y) at a predetermined time (t) is obtained from the wiring schematic, the railroad crossing control table, and the train operation pattern, and the three-dimensional coordinate value (x, y, t) is extracted. Plot the extracted three-dimensional coordinate values in a three-dimensional coordinate space in which the x-axis and y-axis, which are two-dimensional coordinates, and the t-axis, which indicates time, are arranged in three dimensions, and connect them in time series. By displaying the 3D train position image, it is possible to display the train position in 3D by associating the position of two or more trains with the time, so that each person can understand when verifying the functions related to train operation. Differences between trains and train operation patterns can be prevented.
In addition, since the train position display image and the timing diagram can be compared by displaying the three-dimensional train position display image and the timing diagram in an integrated manner, the train position for each time of a plurality of trains, It is possible to grasp a change state of a plurality of signals related to the train position.

[7. Explanation of simulation operation of level crossing control function unit]
In the second embodiment, as in the first embodiment, a train is newly operated from the changed coordinate point by directly operating the train position on the three-dimensional coordinate space by operating a pointing device or the like to change the coordinate point. It is also possible to extract the operation pattern, generate a control signal or the like by simulation of the function of the crossing control device, create a timing diagram, and change the state of the created timing diagram.

  That is, as in the first embodiment, when the train position in the three-dimensional coordinate space is directly operated on the image to change the coordinate point, a train operation pattern is newly extracted from the changed coordinate point, and the railroad crossing control device The state of the created timing diagram can be changed by generating a control signal etc. by simulation of the function of the above, so the train operation pattern can be changed intuitively, and the level crossing control device The simulation of the function can be performed, and it is possible to prevent the difference in understanding among individuals and the omission of the train operation pattern when verifying the function related to the train operation.

[8. Explanation of xy axis plane display operation]
Also in the second embodiment, as in the first embodiment, it is possible to designate a specific time and display the position information of the train on the xy axis plane at the specific time.

  That is, as in the first embodiment, by specifying a specific time and displaying the position information of the train on the xy axis plane at the specific time, the train position at the specific time can be cut out. It is possible to prevent differences in understanding among individuals and pattern leakage of train operations when verifying functions related to train operations.

  In describing the embodiment of the present invention, the processing result integration unit 5 and the three-dimensional train position display image input from the three-dimensional space configuration unit 3 (or the three-dimensional space configuration unit 7) are linked. The timing diagram input from the device function unit 4 (or the level crossing control function unit 8) is integrated and the integrated information is displayed on the display screen of the display unit 6, but of course, the timing diagram is excluded, The three-dimensional space configuration unit 3 (or the three-dimensional space configuration unit 7) may display only a three-dimensional train position display image. In this case, the processing of the interlocking device function unit 4 (or the level crossing control function unit 8) and the processing result integration unit 5 becomes unnecessary.

  In the description of the embodiment of the present invention, the operation time between the stations can be extracted from the train operation pattern, but since there is no train speed information, the extracted time t is discrete. For this reason, even in the three-dimensional train position display image, the train position is displayed based on discrete time, but by adding the train speed information separately, The train position can also be displayed.

In the description of the embodiment of the present invention, for example, a chart as shown in FIG. 4 is illustrated as a train operation pattern. However, an input setting screen is displayed on the display unit 6 under the control of the arithmetic control means 50 or the like. It may be displayed and a train operation pattern may be input by a screen operation of the input operation unit 1.
For example, a template screen on which “train ID”, “route name”, “departure point”, “arrival point”, “departure time”, “arrival time” and the like can be displayed on the display screen of the display unit 6 is displayed. It is also possible to input data from a keyboard or the like.
Similarly, the input setting screen is displayed on the display unit 6 under the control of the arithmetic control means 50 and the like, and the interlocking device function unit 4 (or the crossing control function unit 8) is generated by the screen operation of the input operation unit 1. Information that is desired to be displayed on the timing diagram may be input.
Furthermore, instead of designating a specific time by operating the cursor CR121 on the time axis in the timing diagram shown in FIG. 12, an input setting screen is displayed on the display unit 6 under the control of the arithmetic control means 50 or the like, and the input operation unit 1 A specific time may be designated by an input operation from.

In describing the embodiment of the present invention, the three-dimensional train position display image plots the extracted three-dimensional coordinate values (x, y, t) in the three-dimensional coordinate space, Although connected to the series at once, the extracted three-dimensional coordinate values (x, y, t) such as only at a specified time, from time t = 0 to a specified time, or only during a specified time, etc. Plotting may be performed, and plot points may be connected in time series.
In this case, since the position of the train can be cut out at the time to be noticed, it is possible to prevent differences in understanding among individuals and the pattern leakage of train operation when verifying functions related to train operation.

Moreover, you may comprise so that the function which rotates and displays the three-dimensional coordinate space on a two-dimensional screen in embodiment etc. of this invention may be provided. For example, in the three-dimensional train position display screen of FIG. 5, it is difficult to determine at a glance whether the coordinates of the train of ID41 and the train of ID42 intersect with each other. By rotating and displaying the three-dimensional coordinate space on the two-dimensional screen and changing the train position display image accordingly, it becomes easy to determine whether or not the coordinates of the connection lines of each train intersect (collision).
By the way, as a technique for rotating and displaying a three-dimensional coordinate space on a two-dimensional screen, a known technique provided in graphic software such as three-dimensional CAD can be used.

In describing the embodiment of the present invention, the train position is displayed on the xy plane with respect to a specific time. However, if necessary, the train position is displayed on the xy plane instead of the three-dimensional train position display screen. Position information and time information may be displayed on a two-dimensional plane such as a plane or a yt plane.
In the description of the embodiment of the present invention, the apparatus is described as an apparatus using the three-dimensional train position display method. However, the three-dimensional train position display method of the present invention can express the movement of the train for each time. Therefore, the present invention can be applied to a train approach warning device, a maintenance work support system, a route control device function inspection system, a vehicle organization change support system at a vehicle base, and the like.
