[Means for solving the problem]

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. (1) First embodiment FIG. 1 is a system configuration diagram showing an example of the configuration of a train traffic control system 10 according to a first embodiment. The train traffic control system 10 controls the light emission mode of the front marker lights of a train 21 to be controlled when multiple trains pass each other on a double-track line. The train traffic control system 10 manages the traffic of multiple trains 20 running in opposite directions on the double-track line, and controls changing the light emission mode of the marker lights (hereinafter also referred to as "front marker lights") provided at the front of each train 20. In this embodiment, among the multiple trains 20 on the double-track line, a train that passes the train 21 to be controlled is also referred to as an oncoming train 22. When there is no need to particularly distinguish between the train 21 to be controlled and the oncoming train 22, they are collectively referred to simply as trains 20.

[0011] In addition, in this embodiment, examples of the light emission mode of the front marker lamps include reducing the light amount (hereinafter also referred to as "dimming") and increasing the light amount (hereinafter also referred to as "increasing light"), and examples of changing the light emission mode of the front marker lamps include changing the front marker lamps from high beam to low beam and from low beam back to high beam. In the following description, the former will be mainly mentioned.

[0012] Each train 20 outputs operation mode information indicating its current operation mode to the train traffic control system 10 via a wireless network (not shown). The operation mode information is information indicating, for example, that the train 20 is in an automatic operation mode that does not require a driver (hereinafter also referred to as "fully automatic operation"), or that the train 20 is in a manual operation mode by a driver. Note that the operation mode information may also include information indicating that the train is in an automatic operation mode that requires a driver.

[0013] The train traffic control system 10 includes an input unit 11, a train tracking unit 12, a target section database 13, a determination unit 14, and an output control unit 15.

[0014] The input unit 11 receives operation mode information from each train 20 on a double-track line, and temporarily stores the input operation mode information, for example.

[0015] The train tracking unit 12 receives on-track location information indicating the position of each train 20 on the track in accordance with the results of detection by a detection device (not shown) installed in the field facility along which the train 20 travels. The on-track location information indicates, for example, the distance from a predetermined starting point of each track (down line / up line, etc.) to the position of the train 20.

[0016] The target section database 13 is an example of a database, and pre-stores section information indicating that the section is a dimmed section, which is an example of a target section in which the lighting mode of the front marker light of the controlled train 21 can be changed when multiple trains pass each other.

[0017] Specifically, the target section database 13 is a database that stores, for a train 20 located at a certain position on the track, the range of an oncoming train 20 in which the front marker lights of that train 20 will dazzle the driver of that oncoming train 20, i.e., the section (hereinafter referred to as the "target section") in which light emission control of the front marker lights is required, from the start point to the end point of all tracks. The target section will be explained using Fig. 2, which will be described later. The stored information on the target section is input and referenced by the judgment unit 14.

[0018] Based on the above-mentioned section information and the operation mode information indicating the operation mode of the controlled train 21, the judgment unit 14 judges whether or not to control the lighting state of the front marker light of the controlled train 21 when the trains pass each other in the target section.

[0019] The judgment unit 14 acquires the following information for each train 20 on the line. First, the judgment unit 14 acquires operation mode information via the input unit 11. Next, the judgment unit 14 acquires train location information via the train tracking unit 12. Furthermore, the judgment unit 14 acquires target section information corresponding to the location from the target section database 13. Based on this information, the judgment unit 14 determines whether or not it is necessary to change the light intensity, as an example of the lighting mode, of the front marker lights of each train 20.

[0020] The determination unit 14 manages a dimming necessity flag. The dimming necessity flag corresponds to, for example, the determination result of the light intensity change made by the determination unit 14. When the dimming necessity flag is "necessary (1)", it indicates that dimming of the front marker lights is necessary, and when the dimming necessity flag is "not necessary (0)", it indicates that dimming of the front marker lights is not necessary.

[0021] The output control unit 15 outputs a control command for the lighting mode of the front marker lights to the control target train 21 in accordance with the determination result by the determination unit 14. When an oncoming train 22 is located within the target section based on the track position information, the output control unit 15 outputs a control command for the lighting mode of the front marker lights to the control target train 21 in accordance with the determination result by the determination unit 14.

[0022] The output control unit 15 refers to the dimming necessity flag for each train 20 on the line as the determination result of the determination unit 14 regarding the change in light intensity, and outputs a control command to dim the front marker lights if the dimming necessity flag is "necessary (1)", while it outputs a control command to turn the front marker lights to full brightness if the dimming necessity flag is "not necessary (0)". Note that in this embodiment, for example, setting the light intensity of the front marker lights to maximum is referred to as "full brightness", while changing the light intensity of the front marker lights from maximum to less than maximum is referred to as "dimming".

[0023] The output control unit 15 outputs a control command to the control target train 21 to decrease the light intensity of the front marker lights. After that, when the control target train 21 has completed passing the oncoming train 22 in the target section, the output control unit 15 outputs a control command to the control target train 21 to increase the light intensity of the front marker lights.

[0024] Furthermore, the output control unit 15 may output, as a control command, for example, a command to change the light emission mode of the front marker lights from high beam to low beam to the control target train 21. After that, when the control target train 21 has completed passing the oncoming train 22 in the target section, the output control unit 15 outputs, as a control command, a command to change the light emission mode of the front marker lights from low beam to high beam to the control target train 21.

[0025] The train operation management system according to this embodiment is equipped with an obstacle detection device (not shown) that detects obstacles (e.g., objects, people) on the route, and when the obstacle detection device detects an obstacle within a target section of the route, the output control unit 15 may output a control command to multiple passing trains to change the light emission mode of their front marker lights to high beam.

[0026] In addition, the train operation management system according to this embodiment is equipped with an obstacle detection device (not shown) that detects obstacles (e.g., objects, people) on the route, and when the obstacle detection device detects an obstacle within a target section of the route, the output control unit 15 may output a control command to multiple passing trains to change the light emission mode of their front marker lights to high beam.

[0027] The output control unit 15 may set a target section taking into consideration, for example, houses adjacent to the tracks, and when it is assumed that an oncoming train is always present in the target section, it may dim the front marker lights or set them to low beam as described above. In this way, it is possible to make it less likely that the light from the front marker lights will affect houses adjacent to the tracks.

[0028] The train 20 outputs operation mode information regarding the current operation mode to the train traffic control system 10. The driver or a vehicle attendant sets the operation mode information by operating keys or switches in the driver's cab. In addition, the train 20 changes the light emission mode of the front marker lights in response to a control command from the train traffic control system 10.

[0029] 2 is a diagram showing an example of information related to the target section stored in the target section database 13 according to this embodiment. The example shown in the figure shows an example of a situation seen from above in which a controlled train 21, which is an example of the train 20 described above, is located at point d141 on track t131 and passes an oncoming train 22, which is also an example of the train 20 described above, located on track t232.

[0030] The illumination range 51 is a range that may cause dazzlement to the driver of the other train 20 traveling in the opposite direction when, for example, the front marker lights of one train 20 are fully lit. Note that it is not limited to the driver, but may also be, for example, other people on board the train 20.

[0031] Track t2 target section S 12 (d1)62 is a section in which dimming control of the front marker lights of the controlled train 21 is required to prevent dazzling the driver of the oncoming train 22 on track t232 when the front of the oncoming train 22 is located within the section.

[0032] Far end of track t2 target section F 12 (d1) 72 is the target section S of track t2 12 (d1) 62 is the far end as seen from the controlled train 21, and the front end of the oncoming train 22 is at the far end F of the track t2 target section.12 (d1) If the vehicle approaches closer than 72, dimming control of the front marker lights is initiated.

[0033] Near end N of target section of line t2 12 (d1) 82 is the target section S of track t2 12 (d1) 62 is the near end seen from the controlled train 21, and the front of the oncoming train 22 is the near end N of the target section of the track t2. 12 (d1) If the vehicle approaches closer than 82, the dimming control of the front marker lights is terminated and the lights are returned to full illumination.

[0034] The oncoming train 22 is not necessarily located on a single track. For example, in an overtaking station or a quadruple track section, the oncoming train 22 is located on a plurality of tracks. In this case, in this embodiment, the target section is also assigned to each track.

[0035] Track t3 target section S 13 (d1)63 is a section in which dimming control of the front marker lights of the controlled train 21 is required to prevent dazzling the driver of the oncoming train 22 on track t333 when the front of the oncoming train 22 is present in that section.

[0036] Far end of track t3 target section F 13 (d1) 73 is the target section S of track t3 13 (d1) 63 is the far end as seen from the controlled train 21, and the front end of the oncoming train 22 is at the far end F of the track t3 target section. 13 (d1) If the vehicle approaches closer than 73, dimming control of the front marker lights is initiated.

[0037] Near end N of target section of line t3 13 (d1) 83 is the target section S of track t3 13 (d1) 63 is the near end seen from the controlled train 21, and the front of the oncoming train 22 is the near end N of the target section of the track t3. 13 (d1) If the vehicle approaches closer than 83, the dimming control of the front marker lights is terminated and the lights are returned to full illumination.

[0038] In this embodiment, the target section, the near end of the target section, and the far end of the target section are expressed as follows according to the combination of lines. railway t j Target section S ij (d i ): The train to be controlled 21 is on track t i Point d above i When you are on the track, j A section where dimming control of the front marker lights of the controlled train 21 is required to prevent dazzling the driver of the oncoming train 22 above. railway t j Target section far end F ij (d i ): The train to be controlled 21 is on track t i Point d above i When the line is located at j Target section S ij (d i ) from the perspective of the controlled train 21 railway t j Near end of target section N ij (d i ): The train to be controlled 21 is on track t i Point d above i When the line is located at j Target section S ij (d i ) near end as seen from the controlled train 21

[0039] 3 is a flowchart showing an example of the procedure of the light intensity change determination process according to this embodiment. The light intensity change determination process is executed by the determination unit 14 in the train traffic control system 10 according to the first embodiment. The light intensity change determination process is executed for, for example, all trains 20 on the line.

[0040] In step S110, the judgment unit 14 first initializes the dimming necessity flag to "not necessary (0)." In step S120, the judgment unit 14 acquires and refers to the operation mode information of the train 20 (hereinafter referred to as "train A") to be judged from the input unit 11. In step S130, the judgment unit 14 executes step S140 if train A is subject to light emission control, and terminates the light intensity change judgment process if train A is not subject to light emission control.

[0041] The criteria for determining whether or not a train 20 is subject to the light emission control of the front marker lights by the determination unit 14 include, for example, the following: That is, as a first example, if the determination unit 14 limits the trains 20 that are subject to the light emission control of the front marker lights to automatically operated trains and the light intensity of manually operated trains is operated by the driver, the automatically operated trains are subject to the light emission control and the manually operated trains are not subject to the light emission control.

[0042] As a second example, the judgment unit 14 considers both automatically operated trains and manually operated trains to be trains that are subject to the light emission control of the front marker lights, and if it is desired to prevent at least one of delays and forgetting by the driver of a manually operated train in adjusting the light intensity, then either automatically operated trains or manually operated trains are subject to the control, and there are no non-subject trains.

[0043] In step S140, the decision unit 14 receives from the train tracking unit 12 the track t i and location d i In step S150, the determination unit 14 repeatedly executes steps up to step S190 for the number of tracks on the line that are the subject of light emission control by the train traffic control system 10.

[0044] In step S160, the determination unit 14 determines the track t on which the train A is located from the target section database 13. i , point d i Corresponding to the line t j Target section far end F ij (d i ), and track tj Near end of target section N ij (d i ) to obtain target section information.

[0045] In step S170, the decision unit 14 receives the train tracking information from the train tracking unit 12. j Target section far end F ij (d i ) and railway line t j Near end of target section N ij (d i ), and obtains track location information regarding whether the front of the oncoming train 22 is located between the track t j Target section far end F ij (d i ) and railway line t j Near end of target section N ij (d i ) The determination unit 14 executes step S180 if the front of the oncoming train 22 is located within the section, and executes step S190 if the front of the oncoming train 22 is not located within the section.

[0046] In step S180, the determination unit 14 sets the dimming necessity flag to “necessary (1).” In step S190, the determination unit 14 repeatedly executes steps S150 to S170 described above.

[0047] The train traffic management system 10 of this embodiment is a train traffic management system that controls the lighting mode of the front marker lights of a controlled train 21 when multiple trains pass each other on a double-track line, and is equipped with: a database 13 in which section information indicating a target section in which the lighting mode of the front marker lights of the controlled train 21 can be changed when multiple trains pass each other; a judgment unit 14 that judges whether or not to control the lighting mode of the front marker lights of the controlled train 21 when trains pass each other in the target section based on the section information and operation mode information indicating the operation mode of the controlled train 21; and an output control unit 15 that outputs a control command for the lighting mode of the front marker lights of the controlled train 21 to the controlled train 21 depending on the judgment result by the judgment unit 14.

[0048] In this way, the lighting state of the front marker lights of the train 21 to be controlled passing each other on a double track line can be made less likely to affect the operation of the oncoming train 22.

[0049] The train traffic management system 10 according to this embodiment includes an input unit 11 to which operation mode information of each train on a double-track line is input, and a train tracking unit 12 to which on-track position information indicating the position of each train 20 on the line is input, and when an oncoming train 22 is located within the target section based on the on-track position information, an output control unit 15 outputs a control command to the target train 21 for controlling the lighting mode of the front marker lights, depending on the judgment result by the judgment unit 14.

[0050] In this embodiment, the output control unit 15 outputs a control command to the controlled train 21 to reduce the light intensity of the front marker lights. In this way, the light intensity of the front marker lights of the controlled train 21 passing by on a double-track line is reduced, making it possible to make it less likely that the light emission mode of the front marker lights of the controlled train 21 will affect the operation of the oncoming train 22.

[0051] In this embodiment, when the controlled train 21 has completed passing the oncoming train 22 in the target section, the output control unit 15 outputs a control command to the controlled train 21 to increase the light intensity of the front marker lights. In this way, once the light emission mode of the front marker lights of the controlled train 21 reaches a state where it does not affect the operation of the oncoming train 22, the controlled train 21 can be easily seen by surrounding staff, passengers, people passing through the railroad crossing, and automobiles, etc., because the light emission mode of the front marker lights of the controlled train 21 is now high beam.

[0052] In this embodiment, the output control unit 15 outputs a control command to change the light emission mode of the front marker lights from high beam to low beam to the controlled train 21. In this way, the light emission mode of the front marker lights of the controlled train 21 passing each other on a double-track line becomes low beam, making it possible to make it less likely that the light emission mode of the front marker lights of the controlled train 21 will affect the operation of the oncoming train 22.

[0053] In this embodiment, when the target train 21 has completed passing the oncoming train 22 in the target section, the output control unit 15 outputs a control command to the target train 21 to change the light emission mode of its front marker lights from low beam to high beam. In this way, once the light emission mode of the target train 21's front marker lights no longer affects the operation of the oncoming train 22, the target train 21 can be easily seen by surrounding staff, passengers, people passing through the crossing, and vehicles, etc., because the light emission mode of the target train 21's front marker lights is now high beam.

[0054] In this embodiment, the operation mode information includes, as operation modes of a plurality of trains, fully automatic operation, which does not require a driver, and manual operation.

[0055] In this embodiment, an obstacle detection device (not shown) is provided to detect obstacles on the line, and when the obstacle detection device detects an obstacle in the target section of the line, the output control unit 15 outputs a control command to multiple passing trains to increase the light intensity of their front marker lights. This makes it easier for the controlled train 21 and the oncoming train 22 to find the obstacle.

[0056] In this embodiment, an obstacle detection device (not shown) is provided to detect obstacles on the track, and when the obstacle detection device detects an obstacle in a target section of the track, the output control unit 15 outputs a control command to multiple passing trains to change the light emission mode of their front marker lights to high beams. This makes it easier for the controlled train 21 and the oncoming train 22 to find the obstacle.

[0057] (2) Second embodiment The train traffic control system according to the second embodiment has almost the same configuration and operation as the train traffic control system according to the first embodiment, so a description of the similar configuration and operation will be omitted and the following description will focus on the differences.

[0058] In the first embodiment, the judgment unit 14 judges whether or not to change the light intensity as an example of the light emission mode of the front marker light when an oncoming train 22 is present in the target section, but in the second embodiment, when the oncoming train 22 is an automatically operated train, the judgment unit 14 may judge that no dimming control should be performed to prevent dazzling of the driver because the oncoming train 22 does not have a driver on board.

[0059] In this embodiment, when the oncoming train 22 passing the control target train 21 is, for example, a fully automated train that does not require a driver, the output control unit 15 does not output a control command to the control target train 21 to change the light emission mode of the front marker lights, whereas when the oncoming train 22 passing the control target train 21 is, for example, an automated train or a manually operated train that requires a driver, the output control unit 15 outputs a control command (for example, a control command to reduce the light intensity of the front marker lights, a control command to set the front marker lights to low beam) to the control target train 21 while the oncoming train 22, which is an automated train or a manually operated train that requires a driver, is located in the target section. In this way, it is possible to make it less likely that the light emission mode of the front marker lights of the control target train 21 passing by on a double-track line will affect the operation of the oncoming train 22, as necessary.

[0060] Fig. 4 is a flowchart showing an example of the procedure for the light intensity change determination process in the second embodiment. In the illustrated example, the determination unit 14 of the train traffic control system 10 determines whether or not it is necessary to change the light intensity of the front marker lights, taking into consideration the operation mode information of the oncoming train 22. Note that the flowchart shown in Fig. 4 is almost the same as the flowchart shown in Fig. 3, so a description of the similar procedures will be omitted and the following description will focus on the differences.

[0061] In the flowchart shown in FIG. 4, for example, the following steps S171 and S172 are added after step S170 in the flowchart shown in FIG.

[0062] In step S170, if the front end of the oncoming train 22 is located within the target section, the determination unit 14 executes step S171. j Target section far end F ij (d i ) and railway line t j Near end of target section N ij (d i ) and obtains operation mode information of the oncoming train 22 whose head is located between the oncoming train 22 and the oncoming train 22.

[0063] In this embodiment, the operation mode information includes, as operation modes of a plurality of trains, automatic operation that does not require a driver, automatic operation that requires a driver, and manual operation.

[0064] In step S172, the determination unit 14 determines whether the line t j Target section far end F ij (d i ) and railway line t j Near end of target section N ij (d i), if the operation mode information of the oncoming train 22 whose front end is located between the oncoming train 22 and the train A is, for example, a fully automatic train that does not require a driver, then in step S190 described above, a loop is executed between steps S150 for the number of tracks, whereas if the train is not, for example, a fully automatic train that does not require a driver (for example, an automatic train that does require a driver), then in step S180 described above, the dimming necessity flag for train A is set to "required (1)".

[0065] Because the dimming necessity flag is "Needed (1)", the output control unit 15 outputs a control command to the train 20 to reduce the light intensity, which is an example of the light emission mode of the front marker lights. As a result, the train 20 reduces the light intensity of the front marker lights in response to the control command, so that the driver of the oncoming train 22 is less likely to be affected in his driving by the light from the front marker lights of the train 20, which is the train 20 to be controlled.

[0066] Furthermore, based on the operation mode information of the oncoming train 22 of the train 21 to be controlled input from the input unit 11, the judgment unit 14 judges that it is necessary to change the brightness of the front marker light of the train 21 to be controlled if there is at least one oncoming train 22 on the target section that is a train other than, for example, a fully automatic train that does not require a driver (for example, an automatic or manually operated train that requires a driver).

[0067] By adopting such an operation, when the only oncoming trains 22 passing on the line are, for example, fully automatic trains that do not require a driver, it is possible to avoid unnecessary control of the lighting mode of the front marker lights.

[0068] In addition, with this configuration, it is possible to control the change in light intensity of the train's front marker lights only when necessary depending on the operating mode of the oncoming train.
