Below, a ground control device and route provision method according to an embodiment of the present disclosure will be described in detail based on the drawings.

Embodiment 1.
FIG. 1 is a diagram showing a configuration example of a ground control device 30 according to the first embodiment. The ground control device 30 is connected to the train 10 and the interlock device 20. The ground control device 30 provides a route to the train 10 based on information acquired from the train 10 and the interlocking device 20. The ground control device 30 includes an interlocking information acquisition section 31, a position information acquisition section 32, a storage section 33, and a control section 34.

The interlocking information acquisition unit 31 receives from the interlocking device 20 a ground signal indicating the display information of the wayside signal, a holding signal that retains the display information after the train 10 enters the route assigned to the train 10, and a signal of the switch. Obtain interlocking information including direction information. The interlocking information acquisition unit 31 may acquire the interlocking information from the interlocking device 20 through wired communication, or may acquire the interlocking information through wireless communication.

FIG. 2 is a diagram for explaining ground signals included in the interlocking information acquired from the interlocking device 20 by the interlocking information acquisition unit 31 of the ground control device 30 according to the first embodiment. FIG. 2 shows ground signals and holding signals for route 5R corresponding to route R1005. The ground signal is a signal corresponding to the appearance of a ground signal. The ground signal is a signal that sets a route for the train 10, that is, gives the train 10 a route, causing it to move up (progress), and when the train 10 enters the inside of the route, it causes the train 10 to fall (stop). Note that the traveling direction of the train 10 is from left to right in the figure, and the same applies to the figures described below. The same applies to the traveling directions of trains 11 and 12, which will be described later.

FIG. 3 is a diagram for explaining a holding signal included in the interlocking information acquired from the interlocking device 20 by the interlocking information acquisition unit 31 of the ground control device 30 according to the first embodiment. FIG. 3 shows the ground signal and holding signal for route 5R corresponding to route R1005. The holding signal is information necessary for assigning a route to the train 10. The holding signal is a signal for holding current information, that is, holding the route, even after the train 10 enters the inside of the route. The holding signal is a signal created based on the above-mentioned ground signal, locking information of a switch (not shown), etc., and is assumed here to be outputted by the interlocking device 20 as interlocking information. Establishment of the hold signal corresponds to the rise (advancement) of the ground signal, and failure of the hold signal corresponds to fall (stop) of the ground signal. For example, the rise (advancement) of the ground signal and the establishment of the hold signal are represented by a signal of "1", and the drop (stop) of the ground signal and the failure of the hold signal to be established are represented by the signal of "0".

FIG. 4 is a diagram illustrating an example of the interlocking information acquired from the interlocking device 20 by the interlocking information acquisition unit 31 of the ground control device 30 according to the first embodiment, and the on-track positions of the trains 11 and 12. Note that the trains 11 and 12 shown in FIG. 4 are similar to the train 10 shown in FIG. 1. In the following description, the preceding train 11 may be referred to as a first train, and the following train 12 may be referred to as a second train. In FIG. 4, the ground control device 30 assigns a route R1005 to the preceding train 11, and assigns a route R1004 to the following train 12. In the situation where the trains 11 and 12 are on the track as shown in FIG. Regarding the course 6R corresponding to R1006, the information that the ground signal has fallen (stopped), the holding signal is not established, and the direction of the point device 51 is reversed is acquired as interlocking information.

Returning to the explanation of FIG. The position information acquisition unit 32 acquires position information indicating the on-track position of the train 10 from the train 10. The position information acquisition unit 32 acquires position information from the train 10 by wireless communication. Note that when a wireless communication device (not shown) capable of wireless communication with the train 10 is installed on the ground, the wireless communication device acquires position information from the train 10 by wireless communication, and the position information acquisition unit 32 The position information of the train 10 may also be acquired from. In the example of FIG. 4, the position information acquisition unit 32 acquires the position information that the train 11 is on the line across blocks B1006 and B1007, and the position information that the train 12 is on the line across blocks B1001. Get information.

The storage unit 33 stores route identification information, blocks included in the route, information on the direction of the point equipment on the route, and information about the route that can be given to the train 10 by the ground control device 30. A route database 331 in which location information is defined is stored.

FIG. 5 is a diagram showing an example of the route database 331 stored in the storage unit 33 of the ground control device 30 according to the first embodiment. In the route database 331 shown in FIG. 5, "route" is route identification information, "route block" is a block included in the route, and "ground signal" and "holding signal" are signals corresponding to the route. The "point direction" is information about the direction of the point included in the route, and the "point location" is information about the position of the point. Note that if a route includes multiple points, the route database 331 defines the combination of "point direction" and "point position" for each point for the corresponding route. Hold. In the example of Fig. 5, the "point device position" is specified by the block number of the block included in the route and the position within the block, but if the position of the point device within the block can be specified, other It may be specified using the following method. Here, as shown in FIGS. 4 and 5, it is shown that the switch 51 is located at the end of the block B1003.

The control unit 34 operates based on the interlocking information acquired by the interlocking information acquisition unit 31, the position information acquired by the position information acquisition unit 32, and the route information defined in the route database 331 stored in the storage unit 33. A route is given to the train 10. Specifically, the control unit 34 controls the train 10 so that the direction of the point ahead of the train 10 on the track indicated by the position information in the direction of travel matches the definition of the route database 331. Provide routes corresponding to the 10 courses.

Here, as a comparative example, a case will be described in which the control unit 34 requires that the directions of all the points in the route given to the train 10 match the definition of the route database 331. In this case, the control unit 34 refers to the fact that the ground signal indicates lifting (progress) when the train 10 is on the outside of the track, and indicates that the hold signal is on when the train 10 is on the track inside the track. In order to assign a route, the directions of all the points in the route need to be the directions defined in the route database 331 in any case.

FIG. 6 is a diagram showing the state of the preceding train when a partially overlapping route is given to the following train as a comparative example. FIG. 6 shows a state in which the train 12 to which the route R1004 was assigned in FIG. 4 has traveled to the end of the route R1004 and a new route R1006 is assigned to the train 12. After the train 11, which is the preceding train, passes the switch 51, a different route R1006 is given to the train 12, which is the following train, so the interlocking device 20 changes the direction of the switch 51. Convert from anti-position to normal position. When the direction of the switch 51 is changed from the reversed position to the normal position, the selection condition for the route R1005 for the train 11, that is, "switch 51: reversed" no longer holds true. In such a case, the train 11 will not be given a route, so the train 11 may make an emergency stop with an uncertain route. In order to avoid a situation where the train 11 comes to an emergency stop, the control unit 34 needs to assign route R1006 to the train 12 after the train 11 passes the end of route R1005, thereby improving the operation efficiency of the train 12. becomes worse.

In the example of FIG. 6, the train 11 is passing through the switch 51, so even if the direction of the switch 51 is changed from reverse to normal, a problem will not occur during the actual running of the train 11. do not. Therefore, in the present embodiment, the control unit 34 controls the train 11 so that the direction of the point device ahead of the track position of the train 11 indicated by the position information in the direction of travel matches the definition of the route database 331. A route corresponding to the course of the train 11 is assigned to the train 11. That is, the control unit 34 does not inquire about the direction of the switch 51 that the train 11 has passed on the route given to it. FIG. 7 is a first diagram showing the state of the preceding train when the control unit 34 of the ground control device 30 according to the first embodiment gives the following train a partially overlapping route. The difference from FIG. 6 is that since the train 11 has passed the switch 51, the condition for the direction of the switch 51 in the route R1005 assigned to the train 11 is no longer present in the table at the top left. be. Thereby, the control unit 34 can provide correct routes to the trains 11 and 12. Since the control unit 34 can provide the route R1006 to the train 12 before the train 11 passes the end of the route R1005, it is possible to improve the operating efficiency of the train 12 compared to the comparative example.

FIG. 8 is a second diagram showing the state of the preceding train when the control unit 34 of the ground control device 30 according to the first embodiment gives the following train a partially overlapping route. The difference from FIG. 7 is that the train 12 is moving inward on route R1006. As a result, in the upper right table showing the interlocking information, the ground signal corresponding to route 6R has been changed from hoisting (progress) to falling (stop). Even when the train 12 moves inward on the route R1006, the control unit 34 can provide the correct route to the trains 11 and 12. As described above, the control unit 34 refers to the fact that when the train 10 is on the track outside the route, the ground signal is in the up (progress) position, and the directions of all the points in the route are set to the route. It is assumed that the direction is defined in the database 331. On the other hand, the control unit 34 refers to the fact that the holding signal is established when the train 10 is located inside the route, and controls the control unit 34 to refer to the fact that the hold signal is established when the train 10 is located on the inside of the track, and to It is assumed that the direction of the point is the direction defined in the route database 331.

In this way, the control unit 34 controls the train 11 on the inside of the route to select the first point where the direction of the point device ahead of the track position of the train 11 in the direction of travel is in the direction defined in the route database 331. A route is provided, and a second route in which the directions of all the switches are in the direction defined in the route database 331 is provided to the train 12 which is the train following the train 11 and is located outside the route.

The operation of the control unit 34 to assign a route to the train 10 will be explained using a flowchart. FIG. 9 is a flowchart showing an operation in which the control unit 34 of the ground control device 30 according to the first embodiment provides a route to the train 10. The control unit 34 extracts, from the route database 331, a route that is in the same direction as the specified direction, that is, in the same direction as the traveling direction of the train 10, and that includes a block at the rear of the train 10 (step S101). Note that since a plurality of routes may be assigned to the train 10, the control unit 34 excludes routes that have already been selected from being extracted in step S101. The control unit 34 selects one route from the extracted routes (step S102). If the selected route is not a course-compatible route (step S103: No), the control unit 34 registers the route in the candidate list (step S104). A route corresponding route is a route that requires reference to a ground signal or a held signal, and is a route that involves branching around a station or the like. A route that is not a course-compatible route is a route that does not require reference to ground signals or held signals, and is a route that does not have branches, such as between stations. If the selected route is a route compatible route (step S103: Yes), the control unit 34 performs a route compatible route selection condition checking process for the route (step S105). The detailed operation of the route corresponding route selection condition checking process will be described later.

If the selection condition is satisfied (step S106: Yes), the control unit 34 registers the route in the candidate list (step S104). If the selection condition is not satisfied (step S106: No), or after step S104, the control unit 34 checks whether all routes extracted in step S101 have been checked (step S107). If there is a route that has not been checked (step S107: No), the control unit 34 returns to step S102 and selects one route from the unselected routes. Thereafter, the control unit 34 repeatedly performs the operations described above. If all routes have been checked (step S107: Yes), the control unit 34 selects the route whose end is farthest from the position of the train 10 from the candidate list, and if there are multiple routes, select the route whose start end is the farthest from the position of the train 10. The closest route is selected (step S108). The control unit 34 gives the selected route to the train 10 (step S109).

FIG. 10 is a first diagram showing an image of a route selected by the control unit 34 of the ground control device 30 according to the first embodiment. When the candidate list includes multiple routes, the control unit 34 selects the route whose end is farthest from the location of the train 10, thereby reducing the number of route selections, that is, the load caused by the operation of selecting a route. can do. FIG. 11 is a second diagram showing an image of the route selected by the control unit 34 of the ground control device 30 according to the first embodiment. When there are multiple routes whose end ends are farthest from the train 10's location on the track, the control unit 34 selects the route whose starting end is closest to the train 10's location on the track, thereby allowing subsequent trains to select the route whose end is farthest from the track location of the train 10. It becomes easier. In this way, when there are multiple routes that can be given to the train 10, the control unit 34 selects the route that has the end farthest from the location of the train 10, and selects the route that has the end farthest away from the track location of the train 10. If there are multiple routes, the route whose starting end is closest to the location of the train 10 is selected. The routes that can be assigned to the train 10 are the routes registered in the candidate list in the flowchart shown in FIG.

Here, the detailed operation of the above-mentioned route corresponding route selection condition checking process will be explained. FIG. 12 is a flowchart showing the route corresponding route selection condition checking process by the control unit 34 of the ground control device 30 according to the first embodiment. The control unit 34 checks whether the front position of the train 10 is included in the starting end block of the selected route (step S201). Step S201 is to confirm whether the train 10 is located outside or inside the route. If the front position of the train 10 is included in the starting end block of the selected route (step S201: Yes), the control unit 34 determines whether the train 10 is located outside the route and whether or not the ground signal is raised. (Step S202). When the ground signal is raised (step S202: Yes), the control unit 34 confirms whether or not the interlocking station premises is a moving block (step S203). Step S203 is to confirm whether the interlocking station premises targeted by the interlocking device 20 is a moving block or a fixed block.

If the interlocking station premises is not a moving block (step S203: No), the control unit 34 checks whether another train 10 is on the route ahead of the rear position of the train 10 (step S204). . If there is no other train 10 on the route ahead of the rear position of the train 10 (step S204: No), the control unit 34 determines that the conditions for the point ahead of the rear position of the train 10 are satisfied. It is confirmed whether or not (step S205). In step S205, the control unit 34 compares the on-track position of the train 10 with the switch position on the corresponding route in the route database 331. If the condition for the switch ahead of the rear position of the train 10 is satisfied (step S205: Yes), the control unit 34 determines that the route corresponding route selection condition is satisfied (step S206).

If the front position of the train 10 is not included in the starting end block of the selected route (step S201: No), the control unit 34 determines whether the train 10's position on the track is inside the route and whether or not the holding signal is established. (Step S207). If the holding signal is established (step S207: Yes), the control unit 34 proceeds to step S203. If the hold signal is not established (step S207: No), or if the ground signal is not lifted (step S202: No), or if another train 10 is on the route ahead of the rear position of the train 10. (Step S204: Yes), or if the condition for the switch ahead of the rear position of the train 10 is not satisfied (Step S205: No), the control unit 34 determines that the route corresponding route selection condition is not satisfied. It is determined that (step S208).

FIG. 13 is a diagram illustrating differences in routes due to blocks within the interlocking station premises to which the control unit 34 of the ground control device 30 according to the first embodiment provides routes. The control unit 34 may give different routes to the trains 11 and 12 depending on the blocking method within the interlocking station premises. In the example of FIG. 13, when the interlocking station premises is a fixed block, the control unit 34 assigns route R1002 to train 11, which is the preceding train, and route R1001 to train 12, which is the following train. On the other hand, when the interlocking station premises is a moving block, the control unit 34 assigns the route R1002 to the train 11 of the preceding train, and the route R1002 to the train 12 of the following train. Because of this difference, the control unit 34 checks whether the interlocking station premises is a moving block or a fixed block in step S203 of the flowchart shown in FIG.

Next, the hardware configuration of the ground control device 30 according to the first embodiment will be described. In the ground control device 30, the storage unit 33 is a memory. The interlocking information acquisition section 31, the position information acquisition section 32, and the control section 34 are realized by a processing circuit. The processing circuit may be a memory that stores a program and a processor that executes the program stored in the memory, or may be dedicated hardware. The processing circuit is also called a control circuit.

FIG. 14 is a diagram showing an example of the configuration of the processing circuit 90 when the processing circuit of the ground control device 30 according to the first embodiment is implemented by the processor 91 and the memory 92. A processing circuit 90 shown in FIG. 14 is a control circuit and includes a processor 91 and a memory 92. When the processing circuit 90 includes a processor 91 and a memory 92, each function of the processing circuit 90 is realized by software, firmware, or a combination of software and firmware. Software or firmware is written as a program and stored in memory 92. In the processing circuit 90, each function is realized by a processor 91 reading and executing a program stored in a memory 92. That is, the processing circuit 90 includes a memory 92 for storing a program by which the processing of the ground control device 30 is executed. This program can also be said to be a program for causing the ground control device 30 to execute each function realized by the processing circuit 90. This program may be provided by a storage medium in which the program is stored, or may be provided by other means such as a communication medium.

In the above program, the interlocking information acquisition unit 31 receives from the interlocking device 20 a ground signal indicating the current status information of the wayside signal, a holding signal that holds the current status information after the train 10 enters the route given to the train 10, and a transfer signal. a first step of acquiring interlocking information including information on the direction of the lever; a second step in which the position information acquisition section 32 acquires position information indicating the on-track position of the train 10 from the train 10; and a control section. 34 is based on the interlocking information, the position information, and the route information defined in the route database 331, the direction of the point device ahead in the direction of travel from the on-track position of the train 10 indicated by the position information is determined by the route database 331. It can also be said that this is a program that causes the ground control device 30 to execute the third step of providing the train 10 with a route corresponding to the course of the train 10 so as to match the definition.

Here, the processor 91 is, for example, a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor). The memory 92 may also be a nonvolatile or volatile memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ROM), or EEPROM (registered trademark) (Electrically EPROM). This includes semiconductor memory, magnetic disks, flexible disks, optical disks, compact disks, mini disks, and DVDs (Digital Versatile Discs).

FIG. 15 is a diagram showing an example of the configuration of the processing circuit 93 in the case where the processing circuit of the ground control device 30 according to the first embodiment is implemented by dedicated hardware. The processing circuit 93 shown in FIG. 15 is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of these. applicable. Regarding the processing circuit 93, a part may be realized by dedicated hardware, and a part may be realized by software or firmware. In this way, the processing circuit 93 can realize each of the above functions using dedicated hardware, software, firmware, or a combination thereof.

As explained above, according to the present embodiment, in the ground control device 30, the storage unit 33 stores route identification information, blocks included in the route, and route information for routes that can be assigned to the train 10. A route database 331 in which information on the direction of the point device and information on the position of the point device is defined is stored. Based on the interlocking information acquired from the interlocking device 20, the positional information acquired from the train 10, and the route information defined in the route database 331, the control unit 34 moves from the on-track position of the train 10 indicated by the positional information. A route corresponding to the course of the train 10 is given to the train 10 so that the direction of the forward point in the traveling direction matches the definition of the route database 331. Thereby, the ground control device 30 can improve the safety and operation efficiency in the operation of the train 10.

Embodiment 2.
In Embodiment 2, a case will be described in which the storage unit of the ground control device further stores a point database in which position information of the point device is defined.

FIG. 16 is a diagram showing a configuration example of a ground control device 30a according to the second embodiment. The ground control device 30a is the same as the ground control device 30 of the first embodiment shown in FIG. 1, except that the storage section 33 is replaced with a storage section 33a. The storage unit 33a stores a route database 331 and a switch database 332. The point database 332 indicates the blocks in which the point devices included in the route defined in the route database 331 are installed and their positions within the blocks.

FIG. 17 is a first diagram showing the positional relationship of the point device database 332 stored in the storage unit 33a of the ground control device 30a and the point device 51 within the block according to the second embodiment. In addition to the route database 331, the storage unit 33a, in the example of FIG. device database 332 is stored. In the point device database 332 shown in FIG. 17, the point device 51 is installed across blocks B1003, B1004, and B1010, and the point L from the start end of block B1003, that is, the end position, This indicates that the block B1004 is at a position of 0 from the starting end, that is, the starting end, and the block B1010 is located at a position of 0, that is, the starting end. Note that since the traveling direction of the train 10 is from left to right in the figure, the left side of each block is taken as the starting end and the right side is taken as the ending end. The storage unit 33a stores point information in a format independent of the route database 331, so even if the route database 331 is changed, the change will not affect the point information, that is, the switch. It is possible to obtain an effect that is not as good as that of the hand tool database 332.

FIG. 18 is a second diagram showing the positional relationship of the point device database 332 stored in the storage unit 33a of the ground control device 30a and the point device 51 within the block according to the second embodiment.
