Description

[Technical Field]

[0001] The present disclosure relates to a ground control device, an on-board control device, a train control system, a route control method, an operation restriction method, and a train control method for controlling train operation. [Background technology]

[0002] Conventionally, an on-board control device mounted on a train measures the train's position and transmits the information to a ground control device, and the ground control device controls the operation of each train based on the train position information of each train received from multiple trains. However, if communication between the on-board control device of a certain train and the ground control device is interrupted, the train's position cannot be determined, and the ground control device cannot control the operation of the train with which communication has been interrupted, as well as subsequent trains.

[0003] To address this problem, Patent Document 1 discloses a technology in which a train control device defines a fixed block section as a section where radio communication has been interrupted, adding to its end the distance required for a train to stop, and sets a stopping limit position at the end of the fixed block section for trains entering the fixed block section, thereby controlling train operation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2014 / 097349 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the above-described conventional technology, a ground control device controls train operation by acquiring information such as the route opening status based on the switchover and locking status of point devices via interlocking devices. During normal train operation control, the ground control device acquires train position information measured by the train itself. However, the train's position can also be determined from track circuit status information, including point devices, acquired from interlocking devices. However, in train-based train position measurement methods, the train's range is generally larger than the actual train position to account for measurement errors. On the other hand, when estimating train position based on track circuit status, the lifting or falling of track circuits can reveal that the train is located on a specific block. In other words, the train position measured by the train and the train position based on track circuit status information can differ. Therefore, if the train position measured by the train indicates that the train is located on a track circuit with an unlocked point device, the ground control device may set a route that passes through the track circuit and includes the unlocked point device. In this case, if the direction of the point device is reversed, there is a risk of the train derailing when backing up.

[0006] The present disclosure has been made in consideration of the above, and aims to provide a ground control device that can appropriately control train operation even when a discrepancy occurs between the train position measured by the train and the train position determined from the interlocking information of the interlocking device. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the object, the ground control device of the present disclosure is characterized by comprising: a first communication unit that receives interlocking information including information on the direction of the points that indicates the branching state of the points from the interlocking device; a second communication unit that receives, via a wireless communication device, on-track information that indicates the on-track position of the train from an on-board control device mounted on the train; and a control unit that, based on the interlocking information and on-track information, selects a route for the train and determines whether to set a reverse-prohibited flag that does not allow the train to reverse, generates route information including the train route and whether the reverse-prohibited flag is set, and controls the generation of route information to be sent from the second communication unit to the on-board control device via the wireless communication device. [Effects of the Invention]

[0008] According to the present disclosure, the ground control device has the advantage of being able to appropriately control train operation even when a discrepancy occurs between the train position measured by the train and the train position determined from the interlocking information of the interlocking device.

[0010] Below, a ground control device, an on-board control device, a train control system, a route control method, an operation restriction method, and a train control method according to embodiments of the present disclosure will be described in detail with reference to the drawings.

[0011] Embodiment 1 Fig. 1 is a diagram showing an example of the configuration of a train control system 600 according to the first embodiment. The train control system 600 includes an interlocking device 100, a ground control device 200, a wireless communication device 300, and an on-board control device 500 mounted on a train 400. In the example of Fig. 1, there is one of each device, but the train control system 600 may include two or more of each device. First, the exchange of information between the devices in the operation control of an actual train 400 will be described.

[0012] FIG. 2 is a diagram illustrating an example of information exchanged between the devices in the train control system 600 according to the first embodiment. Note that FIG. 2 omits the on-board control device 500 mounted on the train 400, and only illustrates the train 400. Although the interlocking device 100 and the ground control device 200 actually control a wide range of routes on which the train 400 travels, for the sake of simplicity, the following description will be limited to control within the range illustrated in FIG. 2. FIG. 3 is a diagram illustrating the routes, blocks, and track circuits on which the train 400 travels, which are controlled by the train control system 600 according to the first embodiment within the range illustrated in FIG. 2. For the sake of convenience in explaining information exchanged between the devices, information such as blocks illustrated in FIG. 3 is omitted from FIG. 2. Note that, as indicated by the arrows on each route in FIGS. 2 and 3, the direction of travel of the train 400 is from left to right in FIGS. 2 and 3. The traffic lights in FIG. 3 indicate to the train 400 whether to proceed toward block B1003 or block B1005. 3, the start point, position within the block, and end point are for block B1001. A block is a unit on the route along which the train 400 runs, and the location of the train 400 can be confirmed by lifting or lowering the track circuit.

[0013] Before the train 400 passes, the interlocking device 100 opens and locks the point 21 in the direction in which the train 400 is traveling, and unlocks the point 21 after detecting the passage of the train 400 based on the track circuit 21T. The interlocking device 100 transmits interlocking information to the trackside control device 200, including information on the direction of the point 21 indicating the direction in which the point 21 is open, i.e., the branch status of the point 21. The information on the direction of the point 21 indicating the branch status of the point 21 is information indicating whether the point 21 is open in the direction of block B1003 or in the direction of block B1005. The interlocking information includes information indicating whether each track circuit is raised or lowered. In the first embodiment, the interlocking information includes information indicating whether the point 21 is locked or unlocked.

[0014] The ground control device 200 receives interlocking information from the interlocking device 100. The ground control device 200 can grasp the train position of the train 400 from information included in the interlocking information that indicates whether each track circuit is raised or lowered. For example, if the track circuit 21T is raised and the track circuit of block B1007 is lowered, the ground control device 200 can grasp that the train 400 has passed block B1005 and is currently located at block B1007.

[0015] Furthermore, the ground control device 200 receives track location information indicating the track location of the train 400 measured by the train 400 from the on-board control device 500 mounted on the train 400 via the wireless communication device 300. Here, the method by which the train 400 measures its train location includes a method of using a tachograph or the like to count the number of wheel rotations of the train 400 and calculate the travel distance, but this method is expected to include errors. For this reason, the train location of the train 400 included in the track location information is larger in the forward and backward directions of the train 400's traveling direction than the actual track location, as shown in FIG. 2 .

[0016] The ground control device 200 selects a route for the train 400 based on the interlocking information received from the interlocking device 100 and the track location information received from the on-board control device 500 of the train 400. Generally, the route along which the train 400 will travel is prepared in advance by the railway company that operates the train 400, so the ground control device 200 selects a route from among the prepared route candidates. Here, as shown in Fig. 2, the track location of the train 400 based on the interlocking information received from the interlocking device 100 is within the range of the track circuit of block B1007, but the train location based on the track location information received from the on-board control device 500 is larger to take measurement error into account and therefore straddles the ranges of blocks B1005 and B1007.

[0017] When the ground control device 200 selects a route for the train 400 based on the train position of the train 400 based on the track location information received from the on-board control device 500, in the example of FIGS. 2 and 3 , the ground control device 200 selects route R1002 including blocks B1005 and B1007. However, the interlocking device 100 may have unlocked the point 21 because the train 400 is passing through the track circuit 21T, i.e., is lifted. If the point 21 is unlocked, the interlocking device 100 may change the opening direction of the point 21 from block B1005 to block B1003. In such a case, if the ground control device 200 assigns route R1002 to the train 400 without performing any special control, the train 400 may derail if the direction of the point 21 is changed and the train 400 reverses.

[0018] Therefore, in this embodiment, the ground control device 200 selects a route for the train 400 based on the interlocking information and the track location information, and determines whether to set a reverse prohibition flag that does not allow the train 400 to reverse. As described above, in the first embodiment, the interlocking information includes information indicating whether the point 21 is locked or unlocked. Therefore, when at least one of the blocks where the train 400 is located in the track location information is a block that constitutes a track circuit 21T including the point 21, the ground control device 200 sets the reverse prohibition flag if the interlocking information includes information that the point 21 is unlocked in the direction of the point 21 that is the route when the train 400 reverses. The ground control device 200 generates route information including the route of the train 400 and whether the reverse prohibition flag is set, and transmits the generated route information to the on-board control device 500 of the train 400 via the wireless communication device 300.

[0019] The on-board control device 500 receives route information from the ground control device 200 via the wireless communication device 300. If a reverse prohibition flag that does not permit the train 400 to reverse is set in the route information, the on-board control device 500 performs control so that the train 400 does not reverse when an operation to reverse the train 400 is received from the driver of the train 400.

[0020] 4 is a diagram showing a state in which the ground control device 200 according to the first embodiment transmits route information in which a reverse-impossible flag is set to the on-board control device 500. As described above, the train position of the train 400 based on the track location information straddles block B1005 and block B1007. However, if the train 400 does not reverse, whether the state of the point 21 of the track circuit 21T including block B1005 is locked or unlocked does not affect the operation of the train 400. In this way, the ground control device 200 can appropriately control the operation of the train 400 even when a discrepancy occurs between the train position measured by the train 400 and the train position determined from the interlocking information of the interlocking device 100.

[0021] The following describes the configuration and operation of each device that makes up the train control system 600. As shown in FIG.

[0022] The communication unit 210 is a first communication unit that receives interlocking information including information on the direction of the point 21 that indicates the branching state of the point 21 from the interlocking device 100.

[0023] The communication unit 220 is a second communication unit that receives track location information indicating the track location of the train 400 from the on-board control unit 500 mounted on the train 400 via the wireless communication unit 300. Note that the ground control unit 200 may perform communication using only one communication unit if the same communication as that performed by the communication unit 210 and the communication unit 220 can be performed using one communication unit.

[0024] Based on the interlocking information and the track location information, the control unit 230 selects a route for the train 400 and determines whether or not to set a reverse prohibition flag that does not allow the train 400 to reverse. The control unit 230 generates route information including the route of the train 400 and whether or not the reverse prohibition flag is set, and controls transmission of this information from the communication unit 220 to the on-board control device 500 via the wireless communication device 300.

[0025] As described above, in the first embodiment, the interlocking information transmitted from the interlocking device 100 includes information indicating whether the point 21 is locked or unlocked. In this case, when at least one of the blocks where the train 400 is located in the track location information is a block that constitutes the track circuit 21T including the point 21, the control unit 230 of the ground control device 200 sets the reverse-impossible flag if the interlocking information includes information that the point 21 is unlocked in the direction of the point 21 that is the path when the train 400 is reversed. At least one of the blocks where the train 400 is located in the track location information is actually the block where the rear of the train 400 is located in the track location information, as shown in Figures 2 and 4 .

[0026] As shown in FIG. 1, an on-board control device 500 mounted on a train 400 includes a communication unit 510 and a control unit 520.

[0027] The communication unit 510 transmits track location information, which indicates the track location of the train 400, to the ground control device 200 that controls the operation of the train 400, via the wireless communication device 300. The communication unit 510 also receives route information from the ground control device 200 via the wireless communication device 300.

[0028] When a reverse prohibition flag that does not permit the train 400 to reverse is set in the route information, the control unit 520 performs control so that the train 400 does not reverse when an operation to reverse the train 400 is received from the driver of the train 400. Note that when a reverse prohibition flag is set in the route information, the control unit 520 may notify the driver of the train 400 that reverse of the train 400 is not permitted. This allows the driver of the train 400 to understand that reverse of the train 400 is not permitted. The control unit 520 may notify the driver of the train 400 that reverse of the train 400 by displaying a message on a driver's cab (not shown) of the train 400 or by audio.

[0029] In the train control system 600, the operation of the interlocking device 100 is as described above. When the wireless communication device 300 receives track location information transmitted from the on-board control device 500 mounted on the train 400, it outputs the track location information to the ground control device 200. In addition, the wireless communication device 300 transmits the route information acquired from the ground control device 200 to the on-board control device 500 mounted on the train 400.

[0030] 5 is a flowchart showing the operation of the ground control device 200 according to the first embodiment. In the ground control device 200, the communication unit 210 receives interlocking information from the interlocking device 100 (step S101). The communication unit 220 receives track location information from the on-board control device 500 mounted on the train 400 via the wireless communication device 300 (step S102). The control unit 230 selects a route for the train 400 based on the interlocking information and the track location information (step S103). Based on the interlocking information and the track location information, the control unit 230 determines whether or not a point on a track circuit corresponding to a track location block where the train 400 is located in the track location information is unlocked (step S104).

[0031] If the points on the track circuit corresponding to the track block are unlocked (step S104: Yes), the control unit 230 sets the reverse prohibition flag (step S105) and generates the selected route and route information indicating that the reverse prohibition flag is set (step S107). On the other hand, if the points on the track circuit corresponding to the track block are locked (step S104: No), the control unit 230 does not set the reverse prohibition flag (step S106) and generates the selected route and route information indicating that the reverse prohibition flag is not set (step S107). The control unit 230 controls the communication unit 220 to transmit the route information. The communication unit 220 transmits the route information to the on-board control device 500 mounted on the train 400 via the wireless communication device 300 (step S108).

[0032] 4 and other figures, the point 21 is represented by a dot, but in reality, the tongue rail, which is the movable part of the point 21, has length, and therefore blocks B1003, B1005, etc. include the movable part of the point 21. Therefore, if the railway company that operates the train 400 stores information about blocks that include movable parts of points in a database in advance, the control unit 230 of the ground control device 200 may perform an operation in step S104 to determine whether the point corresponding to the movable part is unlocked if the block where the train 400 is located according to the track location information corresponds to a block that includes a movable part of a point.

[0033] 3 and the like, route R1002 is defined as the route of the train 400 that includes block B1007, but if, for example, block B1005' (not shown) exists between block B1005 and block B1007 and a route starting from block B1005' is defined in advance in a database or the like by the railway company that operates the train 400, the control unit 230 of the ground control device 200 may select a route with blocks that include as few moving points as possible in step S103. By selecting a route that includes as few moving points as possible, the control unit 230 of the ground control device 200 can control the operation of the train 400 without interfering with normal operations.

[0034] 6 is a flowchart showing the operation of the on-board control device 500 according to the first embodiment. In the on-board control device 500, the communication unit 510 receives route information transmitted from the ground control device 200 via the wireless communication device 300 (step S201). The control unit 520 checks whether a reverse prohibition flag is set in the route information (step S202). If the reverse prohibition flag is set in the route information (step S202: Yes), the control unit 520 notifies the driver of the train 400 that reverse of the train 400 is not permitted (step S203). Furthermore, the control unit 520 does not reverse the train 400 in response to an instruction to reverse the train 400 from the driver of the train 400 (step S204). If the reverse prohibition flag is not set in the route information (step S202: No), the control unit 520 may perform normal control and therefore ends the operation shown in FIG. 6.

[0035] Next, the hardware configuration of the ground control device 200 according to the first embodiment will be described. In the ground control device 200, the communication unit 210 is a communication device capable of communicating with the interlocking device 100. The communication unit 220 is a communication device capable of communicating with the wireless communication device 300. The control unit 230 is 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.

[0036] FIG. 7 is a diagram illustrating an example of the configuration of the processing circuit 90 of the ground control device 200 according to the first embodiment, when the processing circuit is realized by a processor 91 and a memory 92. The processing circuit 90 illustrated in FIG. 7 is a control circuit and includes a processor 91 and a memory 92. When the processing circuit 90 is configured with the processor 91 and the memory 92, each function of the processing circuit 90 is realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in the memory 92. The processing circuit 90 realizes each function by having the processor 91 read and execute the program stored in the memory 92. That is, the processing circuit 90 includes the memory 92 for storing a program that results in the processing of the ground control device 200 being executed. This program can also be said to be a program that causes the ground control device 200 to execute each function realized by the processing circuit 90. This program may be provided by a storage medium on which the program is stored, or by other means such as a communication medium.

[0037] It can also be said that the above program is a program that causes the ground control device 200 to execute the following steps: a first step in which the communication unit 210 receives interlocking information including information on the direction of the point 21, which indicates the branching state of the point 21, from the interlocking device 100; a second step in which the communication unit 220 receives, via the wireless communication device 300, track location information indicating the track location of the train 400 from the on-board control device 500 mounted on the train 400; and a third step in which the control unit 230 selects a route for the train 400 based on the interlocking information and the track location information, determines whether or not to set a reverse-prohibited flag that does not allow the train 400 to reverse, generates route information including the route of the train 400 and whether or not the reverse-prohibited flag is set, and controls the communication unit 220 to transmit the route information to the on-board control device 500 via the wireless communication device 300.

[0038] 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), etc. Furthermore, the memory 92 is, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable ROM), or an EEPROM (registered trademark) (Electrically EPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD (Digital Versatile Disc).

[0039] FIG. 8 is a diagram showing an example of the configuration of the processing circuit 93 in the ground control device 200 according to the first embodiment when the processing circuit is configured with dedicated hardware. The processing circuit 93 shown in FIG. 8 corresponds to, 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 thereof. The processing circuit 93 may be partially realized with dedicated hardware and partially realized with software or firmware. In this way, the processing circuit 93 can realize each of the above-described functions by dedicated hardware, software, firmware, or a combination thereof.

[0040] The hardware configuration of the ground control device 200 has been described above, but the on-board control device 500 also has a similar hardware configuration. In the on-board control device 500, the communication unit 510 is a communication device capable of wireless communication with the wireless communication device 300. The control unit 520 is realized by a processing circuit. The processing circuit may be a memory that stores programs and a processor that executes the programs stored in the memory, or may be dedicated hardware. The processing circuit is also called a control circuit.

[0041] As described above, according to this embodiment, in the train control system 600, the ground control device 200 receives interlocking information from the interlocking device 100, including information about the direction of the point 21, indicating the branching state of the point 21, and receives track location information, indicating the track location of the train 400, from the on-board control device 500 via the wireless communication device 300. Based on the interlocking information and the track location information, the ground control device 200 selects a route for the train 400 and determines whether to set a reverse-prohibited flag that does not allow the train 400 to reverse. The ground control device 200 generates route information including the route of the train 400 and whether the reverse-prohibited flag is set, and transmits the route information to the on-board control device 500 via the wireless communication device 300. Then, when the on-board control device 500 receives the route information from the ground control device 200 and the reverse-prohibited flag is set, the on-board control device 500 controls the train 400 not to reverse when it receives an instruction to reverse the train 400 from the driver of the train 400. As a result, even if a discrepancy occurs between the train position measured by the train 400 and the train position determined from the interlocking information of the interlocking device 100, the ground control device 200 can avoid a situation in which the train 400 derails and appropriately control the operation of the train 400.

[0042] Embodiment 2 In the first embodiment, the ground control device 200 determines whether or not the reverse impossible flag is set based on information indicating whether the point 21 is locked or unlocked, which is included in the interlocking information from the interlocking device 100. In the second embodiment, a case will be described in which the ground control device 200 determines whether or not the reverse impossible flag is set based on information indicating whether the track circuit 21T is raised or dropped, which is included in the interlocking information from the interlocking device 100.

[0043] In the second embodiment, the configurations of the train control system 600, the ground control device 200, and the on-board control device 500 are the same as those in the first embodiment shown in FIG. 1. In the second embodiment, the interlocking information transmitted from the interlocking device 100 includes information indicating whether the track circuit 21T is raised or lowered. In this case, if at least one of the blocks where the train 400 is located in the track location information is a block that constitutes the track circuit 21T including the point 21, the control unit 230 of the ground control device 200 sets the reverse-impossible flag when the interlocking information includes information that the track circuit 21T is raised. At least one of the blocks where the train 400 is located in the track location information is actually the block where the rear of the train 400 is located in the track location information, as shown in FIGS. 2 and 4.

[0044] The control unit 230 can determine whether the train 400 is located on the track circuit 21T as long as the interlocking information includes information indicating whether the track circuit 21T is raised or lowered, even if the interlocking information does not include information indicating whether the point 21 is locked or unlocked, which information was included in the first embodiment. In the second embodiment, it is the ground control device 200 that ultimately determines whether the train 400 is located on the track circuit 21T.

[0045] FIG. 9 is a flowchart showing the operation of the ground control device 200 according to the second embodiment. In the flowchart shown in FIG. 9, the operation from step S101 to step S103 is the same as the operation in the flowchart of the first embodiment shown in FIG. 5. The control unit 230 determines whether or not the track circuit corresponding to the track location block, which is the block where the train 400 is located in the track location information, is raised based on the interlocking information and the track location information (step S111). If the track circuit corresponding to the track location block is raised (step S111: Yes), the control unit 230 sets a reverse prohibition flag (step S105) and generates route information indicating the selected route and the reverse prohibition flag being set (step S107). On the other hand, if the track circuit corresponding to the track location block is lowered (step S111: No), the control unit 230 does not set the reverse prohibition flag (step S106) and generates route information indicating the selected route and the reverse prohibition flag being not set (step S107). The control unit 230 controls the communication unit 220 to transmit the route information. The communication unit 220 transmits the route information to the on-board control device 500 mounted on the train 400 via the wireless communication device 300 (step S108).

[0046] The operation of the on-board control device 500 that receives the route information from the ground control device 200 is the same as in the first embodiment, and therefore a detailed description thereof will be omitted.

[0047] As explained above, according to this embodiment, in the train control system 600, the ground control device 200 determines whether to set the reverse-impossible flag by using information included in the interlocking information indicating whether the track circuit 21T is raised or lowered. Even in this case, the ground control device 200 can obtain the same effects as in the first embodiment. Furthermore, the train control system 600 of the second embodiment can be applied without replacing the interlocking device 100 even in a system in which the existing interlocking device 100 does not include information on whether the point 21 is unlocked or locked, that is, in which only a small amount of interlocking information is transmitted to the ground control device 200.

[0048] The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or different embodiments may be combined with each other. It is also possible to omit or modify parts of the configurations as long as they do not deviate from the gist of the invention. [Explanation of symbols]
