[overall structure]
FIG. 1 is a schematic configuration diagram of a train control system 1 of the present embodiment. In addition, in FIG. 1, it has shown about the case where one obstruction | occlusion is formed between stations for easy explanation. As shown in FIG. 1, in the train control system 1, an on-site traffic signal 12 for restricting the train from entering each station (station A and station B in FIG. 1) serving as a stop as ground equipment, A departure signal 14, a station interlocking device 20, and a ground device 30 for restricting the departure of the train from the station are installed.

  In order to ensure a safe route configuration of the train in the station, the station interlocking device 20 is used between the traffic signals such as the on-site traffic signal 12 and the departure traffic signal 14 installed in the station, and between these traffic signals and the switch. This is a device that realizes fail-safe by providing a chain between them.

  The ground device 30 has a wireless function, and the communicable range (communication range) 32 includes a station premises (installed station) where the device is installed, and is further predetermined before the station traffic lights 12 of the station. The range includes a distance (for example, 100 m). The ground device 30 is communicatively connected to the station interlocking device 20. Through the station interlocking device 20, the signal display of each traffic signal (the on-site traffic signal 12 and the departure traffic signal 14) installed at the station is displayed as needed. Have acquired. The ground device 30 then obtains the current signal display of each traffic signal in the station (the on-site traffic signal 12 and the departure traffic signal 14) acquired from the station interlocking device 20, and each traffic signal of the station or the adjacent station stored in advance. The location (about a kilometer) is sent (transmitted) by radio as needed.

  Further, the ground device 30 transmits operation information related to the section from the station to the adjacent station by radio as needed. Here, the driving information includes driving regulation (including position) set for the corresponding section, temporary speed regulation generated by passage speed, weather conditions, ground construction, and the like. For example, the operation information is acquired directly from a central management device that is installed in a railway company's office and manages the entire line area, or is connected to the central management device and arranged at each station. Via a station transmission device (not shown). The various driving information may be sent not by the ground device 30 but by a station transmission device (not shown) installed at each station.

  Further, an on-board device (ATS on-board device) 50 is mounted on the train 40 traveling on the track R as on-vehicle equipment. The on-board device 50 is equipped with a wireless communication function, and can perform wireless communication with the ground device 30 when located in the communicable range 32 of the ground device 30. Further, wireless communication with the above-described station transmission device is also possible.

  The on-board device 50 performs speed control using a speed check pattern. Specifically, when the current traveling speed exceeds the checking speed determined by the speed checking pattern, a known speed control is performed in which the brake is automatically applied and decelerated. Further, when the onboard device 50 approaches the station and reaches the communicable range 32 of the ground device 30 installed at the station, the onboard device 50 receives traffic signal information and various driving information from the ground device 30. Then, the speed check pattern is updated based on the received data from the ground device 30.

  2 and 3 are diagrams for explaining the update of the speed check pattern in the on-board device 50. FIG. FIG. 2 shows a case where the train 40 is stopped at the A station. In this case, in the on-board device 50 of the train 40, the signal display (departure signal display information) of the departure signal 14A of the A station and the in-ground signal 12B of the B station that is the adjacent station are transmitted from the ground device 30A of the A station. The traffic signal information including the position (the next traffic signal position information in the field, which is expressed in terms of the building planting distance) is received.

  Then, the on-board device 50 is based on the received traffic signal information and is stopped from the current stop position in front of the on-site traffic signal 12B at the B station (for example, several meters before), and a speed check pattern that secures forward protection. Create At this time, based on the driving information received together with the traffic signal information, a speed check pattern is created so as not to exceed a predetermined speed limit.

  And according to the progress display of the departure signal 14A of A station, the train 40 starts driving | running | working toward B station which is the next station (next station) of the advancing direction. At this time, speed control using the created speed check pattern is performed.

  Subsequently, as shown in FIG. 3, the train 40 approaches the B station, which is the next station, and enters the communicable range 32B of the ground device 30B of this B station. And from this ground device 30B, the signal display (signal display information in the field) of the signal B 12B in the station B and the position (departure signal position information of the departure signal 14B of the station B. Expressed in the building planting distance. ) Is received, it is determined whether or not to update the speed check pattern from the signal display of the received signal 12B at the station B.

  That is, if the on-site traffic signal 12B at station B is “progress indication”, the speed check pattern is updated. Specifically, a speed check pattern for starting protection exceeding a predetermined position (stop position at B station) in front of the departure signal 14B at station B is created from the current travel position, and a new speed check pattern is created. Update. The train 40 continues to travel and enters the B station, and stops at the stop position at the B station, that is, before the departure signal 14B.

  On the other hand, if the on-site traffic signal 12B at the B station is “stopped display”, the speed check pattern is not updated, but stops before the on-site signal 12B at the B station according to the current speed check pattern. Next, after the on-site signal 12B changes from “stop display” to “progress display”, the stop position exceeds a predetermined position (ie, stop position at station B) in front of the departure signal 14B at station B. Create and update a new speed check pattern that ensures progressive protection.

  And it starts driving | running | working with the updated speed check pattern and enters B station, and stops in front of the departure signal 14B, ie, the stop position in B station. At this time, speed control is performed using a speed check pattern based on the update.

  Thereafter, as in the case of the stop at the station A shown in FIG. 2, the speed check up to the in-site traffic signal 12 at the next station is performed based on the traffic signal information received from the ground device 30B installed at the station B. Create and update patterns.

And is used as a work area of the ground processing unit 310, and temporarily stores calculation results executed by the ground processing unit 310, data received by the ground wireless communication unit 320, and the like. In the present embodiment, the traffic signal position data 331 and the operation information 332 are stored in the ground storage unit 330.

  The traffic signal position data 331 is data of the position of each traffic signal installed at the station or the adjacent station. FIG. 6 is a diagram illustrating an example of a data configuration of the traffic signal position data 331. As illustrated in FIG. As shown in FIG. 6, the traffic signal position data 331 includes the position of the in-upstream traffic signal 12u installed at the station (A station), the position of the upstream departure traffic signal 14u, the position of the downstream traffic signal 12d, and the downstream departure traffic signal 14d. , The position of the traffic signal 12u in the upstream area installed at the next station in the upward direction (B station), and the position of the traffic signal 12d in the downstream area installed at the next station in the downward direction (Z station) are stored. . In addition, the position of the traffic lights is all expressed in terms of a built-in kilometer.

(B) On-board device 50
FIG. 7 is a block diagram illustrating a functional configuration of the on-board device 50. According to FIG. 7, the on-board device 50 is functionally configured to include an on-board processing unit 510, an on-board wireless communication unit 520, and an on-board storage unit 530.

Perform overall control. In the present embodiment, the on-board processing unit 510 includes a train position calculation unit 511, a speed check pattern creation unit 512, and a speed control unit 513.

  The train position calculation unit 511 calculates the current travel position of the train 40 (expressed as a train position: kilometer) by, for example, counting the number of rotations of the speed generator attached to the axle. Further, while the train is traveling, the current train position is corrected as appropriate by performing wireless communication with an error corrector (not shown) arranged along the track R. The train position calculated by the train position calculation unit 511 is stored as train position data 534.

  The speed verification pattern creation unit 512 creates and updates the speed verification pattern based on the traffic signal information received from the ground device 30. The speed check pattern creation unit 512 corresponds to a creation determination unit, a creation unit, an update determination unit, and an update unit. Specifically, as shown in FIG. 2, when the train 40 is stopped at a station, if the position of the traffic signal 12 of the next station is received from the ground device 30 of the station, the traffic signal 12 of the next station is received. Create a speed check pattern that stops before this, and update it as a new speed check pattern.

  In addition, as shown in FIG. 3, the train 40 travels and approaches the next station, and receives the signal indication of the traffic signal 12 in the next station and the position of the departure signal 14 from the ground device 30 of the next station. If so, it is determined whether or not to update the speed check pattern based on the signal display of the traffic signal 12 at the next station.

  That is, if the next station signal 12 is “progress indication”, it is determined that the speed check pattern is updated. Then, a speed check pattern for stopping at a predetermined position (outside) before the departure signal 14 at the next station is created from the current travel position, and updated as a new speed check pattern. In addition, even if it is not “progress indication”, it may be determined that the speed check pattern is updated if it is an indication (for example, “caution indication”) that allows the in-field traffic signal 12 to enter inward.

  On the other hand, if the signal display of the in-field signal device 12 is a display in which the in-field signal device 12 is prohibited from entering inward, for example, “stop display”, it is determined that the speed check pattern is not updated. In this case, the speed check pattern is updated after the on-site signal 12 changes to “progress indication”.

  The speed check pattern created by the speed check pattern creation unit 512 is stored as speed check pattern data 531.

  The speed control unit 513 controls the traveling speed of the train 40 using the speed verification pattern (speed verification pattern data 531) created by the speed verification pattern creation unit 512. Specifically, brake control is performed.

And data are used as a work area of the on-board processing unit 510, and calculation results executed by the on-board processing unit 510, data received by the on-board wireless communication unit 520, and the like are temporarily stored. The In the present embodiment, the on-vehicle storage unit 530 stores speed check pattern data 531, current station data 532, next station data 533, and train position data 534.

  The current station data 532 is a signal display of each traffic signal installed at the current station and data of the installation position received from the ground device 30. Here, the “current station” is a station where the train 40 is currently located, or a station that has arrived last when traveling between stations.

  FIG. 8 is a diagram illustrating an example of the data configuration of the current station data 532. As shown in FIG. 8, the current station data 532 includes the position and signal display of the traffic signal 12 at the current station and the position and signal display of the departure signal 14.

[Process flow]
FIG. 10 is a flowchart illustrating a travel control process executed by the on-board processing unit 510 in the on-board device 50. As an initial state, it is assumed that the train 40 is stopped at the first station.

  According to FIG. 10, the on-board processing unit 510 first receives the indication of the departure signal 14 of the station and the position of the in-vehicle signal 12 of the next station from the ground device 30 of the station that is stopped (step). A1). Then, if the departure signal 14 of the station becomes “indication of progress” (step A3: YES), the speed check pattern creation unit 512 determines the train based on the received position of the signal 12 in the next station. From the current stop position of 40, a speed check pattern to be stopped before the in-site traffic signal 12 at the next station is created and updated as a new speed check pattern (step A5). Thereafter, traveling is started. At this time, speed control (ATS control) using the speed check pattern is performed (step A7).

  Subsequently, when the vehicle approaches the next station while traveling and is located within the communicable range 32 of the ground device 30 of the next station (step A9: YES), the ground signal 30 of the next station is transmitted from the ground device 30 of the next station. And the position of the departure signal 14 are received (step A11). If the received traffic signal 12 at the next station is “progress indication” (step A13: YES), the speed check pattern creation unit 512 stops from the current travel position before the departure signal 14 at the next station. A speed check pattern is created and updated as a new speed check pattern (step A15).

  On the other hand, if the on-site traffic signal at the next station is “stop indication” (step A13: NO), traveling control using the current speed check pattern is continued. Subsequently, it is determined whether or not the vehicle stops in front of the next-station signal at the next station. If not stopped (step A17: NO), the process returns to step A13. If it stops (step A17: YES), it waits until the on-site traffic signal 12 at the next station becomes “progress indication”. And if the in-traffic signal 12 at the next station becomes “progress indication” (step A19: YES), the speed check pattern creation unit 512 starts from the stop position at a predetermined position before the departure signal 14 at the next station ( A speed check pattern that stops at a stop position in the station is created and updated as a new speed check pattern (step A21). Thereafter, traveling control using the updated speed check pattern is started (step A23).

  If the next station is stopped (step A25: YES), it is determined whether or not the next station is a terminal station on the diagram. If the next station is not the terminal station (step A27: NO), the process returns to step A1, and if the next station is the terminal station (step A27: YES), the travel control process is terminated.

[Action / Effect]
Thus, according to the present embodiment, the ground device 30 installed at each station sends out the current indication and position of the traffic signal at each station, and the position of the traffic signal at the adjacent station as needed. Then, the on-board device 50 mounted on the train 40 that has reached the communicable range 32 of the ground device 30 displays the next traffic signal from the ground device 30 and the traffic signal that passes next. The position check signal is received, and a speed check pattern is generated and updated from the current position so as to stop before the position of the traffic signal that passes next. In other words, regardless of the display of the next traffic light, a speed check pattern that stops before the next traffic light is created, and thereby, traveling control that ensures forward protection is realized.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

In FIG. 11, two on-site traffic signals 12B-1 and 12B-2 are installed at the B station, and the train 40 entering the B station from the A station passes through the on-site traffic signals 12B-2 and 12B-1. .

  In this case, the train 40 stopped at the A station receives the signal indication of the departure signal 14A at the A station and the position of the in-ground signal 12B-2 at the B station from the ground device 30A. After the signal display is changed to “progress display”, a speed check pattern is generated from the current stop position to stop before the on-site signal 12B-2.

  When the train 40 reaches the communicable range 32B of the ground device 30B installed at the station B, the signal display of the on-site signal devices 12B-1 and 12B-2 and the on-site signal device 12B-1 are transmitted from the ground device 30B. And the position of the departure signal 14B. Next, the speed check pattern is recreated / updated according to the signal display of the on-site traffic lights 12B-1 and 12B-2. That is, when it is determined that the inward signal 12B-2 can enter inward, a speed check pattern for stopping before the in-field signal 12B-1 is created / updated from the current traveling position. If it is possible to enter the traffic light 12B-1 inward, a speed check pattern for making a stop at a predetermined position before the departure traffic light 14B (that is, a stop position at the B station) from the current travel position is created / updated.

  Moreover, FIG. 12 is a case where the obstruction | occlusion signal apparatus is installed between stations. In FIG. 12, the block signal 16 is installed between the A station and the B station.

  In this case, in the train 40 stopped at the station A, the signal display of the departure signal 14A and the position of the block signal 16 are received from the ground device 30A, and before the block signal 16 from the current stop position. Create / update the speed check pattern to be stopped. And when the train 40 approaches the block signal 16, it receives the signal indication of the block signal 16 and the position of the signal 12 B in the station B from the ground device 30 installed in the vicinity of the block signal 16.
