Description

[Technical field]

[0001] The present disclosure relates to a wireless train control system that controls train operation through wireless communication and a method for acquiring a train formation number. [Background technology]

[0002] Conventionally, in the railway field, a train formation number is used to identify a train in train operation control, train maintenance work, and the like. For example, Patent Document 1 discloses a technology for acquiring information on the train formation number of a train on which equipment is installed, together with information on the type of equipment installed on the train and information on the status of the equipment, during train maintenance work. Generally, when equipment installed on a train is removed from the train for repair, inspection, and the like, it may be installed on another train instead of the original train. However, by using the technology described in Patent Document 1, information on what kind of train the equipment installed on the train was installed on and how it has been used can be obtained, and such information can be used for maintenance work.

[0003] [Patent Document 1] International Publication No. 2017 / 195408 Summary of the Invention [Problem to be solved by the invention]

[0004] An on-board control device mounted on a train compatible with radio train control recognizes the train set number of the train by using a connector for recognizing the train set number and a DI (Digital Input) input to the connector for recognizing the train set number. The on-board control device is designed so that the connector for recognizing the train set number cannot be replaced while mounted on the train so that the train set number of the train is not changed. The connector for recognizing the train set number is input in binary, and the number of DIs needs to be increased as the train set number increases. For example, if there is a train with 128 sets of trains, the connector for recognizing the train set number needs to have a total of eight inputs, including at least seven DIs for seven bits and one earth. Therefore, there has been a problem in that the on-board control device needs to increase the number of inputs for the connector for recognizing the train set number as the train set number increases, and the hardware configuration needs to be changed.

[0005] The present disclosure has been made in consideration of the above, and aims to obtain a wireless train control system in which an on-board control device can acquire information on the formation number of the train on which it is installed, without having to change the hardware depending on the number of train formations present.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A radio train control system and a train set number acquisition method according to an embodiment of the present disclosure will be described in detail below with reference to the drawings.

[0010] Embodiment FIG. 1 is a diagram showing a configuration example of a radio train control system 40 according to the present embodiment. The radio train control system 40 includes trains 10a and 10b, a ground antenna 30, a radio ground base station 31, a ground control device 32, a ground terminal 33, and a ground network 34. The radio train control system 40 includes two trains, i.e., trains 10a and 10b, in the example of FIG. 1, but may include three or more trains. FIG. 1 shows a state in which the train 10a is stopped at a station 21, and the train 10b is stopped at a storage line or the like. In the following description, the trains 10a and 10b may be referred to as train 10 when they are not distinguished from each other. FIG. 2 is a diagram showing a configuration example of a train 10 according to the present embodiment. The train 10 includes on-board control devices 11 and 12, train information management devices 13 and 14, a radio on-board station 15, and an on-board antenna 16.

[0011] The on-board control devices 11 and 12 are mounted on specified cars of a train 10 having a redundant transmission system (not shown). For example, if the right side in Fig. 2 is the direction of travel of the train 10, the on-board control device 11 is mounted on the leading car of the train 10 as a specified car, and the on-board control device 12 is mounted on the trailing car of the train 10 as a specified car. If the left side in Fig. 2 is the direction of travel of the train 10, the on-board control device 11 is mounted on the trailing car of the train 10 as a specified car, and the on-board control device 12 is mounted on the leading car of the train 10 as a specified car.

[0012] The on-board control device 11 includes a board that functions as an on-board control device in each transmission system in order to transmit control information and the like with on-board devices (not shown) in the redundant transmission system. Identification information for communication in one of the transmission systems is set on the board that functions as the on-board control device. For example, when the redundant transmission system is configured with two systems, system 1 and system 2, the on-board control device 11 includes a board for an on-board control device that transmits control information and the like with on-board devices in system 1 and functions as one on-board control device, and a board for an on-board control device that transmits control information and the like with on-board devices in system 2 and functions as one on-board control device. A unique MAC (Media Access Control) address, which is the above-mentioned identification information and is necessary for communication with on-board devices in the transmission system, is set on each board for the on-board control device during the manufacturing stage of the board for each on-board control device or during the manufacturing stage of the on-board control device 11. For example, when system 1 and system 2 of the redundant transmission system are networks compatible with Ethernet (registered trademark), the MAC address is an address for communication on one channel of Ethernet. In this way, the on-board control device 11 appears to be composed of a single housing, but has boards for on-board control devices that function as on-board control devices in a number corresponding to the number of redundant transmission systems. In the example of Fig. 2, the on-board control device 11 has two boards for on-board control devices that function as on-board control devices for two systems, that is, two MAC addresses are set for the on-board control device 11 during its manufacturing stage.

[0013] Similarly, the on-board control device 12 includes a board that functions as an on-board control device in each transmission system in order to transmit control information and the like with on-board devices (not shown) in the redundant transmission system. Identification information for communication in one of the transmission systems is set on the board that functions as the on-board control device. For example, when the redundant transmission system is configured with two systems, system 1 and system 2, the on-board control device 12 includes a board for an on-board control device that transmits control information and the like with on-board devices in system 1 and functions as one on-board control device, and a board for an on-board control device that transmits control information and the like with on-board devices in system 2 and functions as one on-board control device. The board for each on-board control device is set with the above-mentioned identification information, which is a unique MAC address required for communication with on-board devices in the transmission system, during the manufacturing stage of the board for each on-board control device or the manufacturing stage of the on-board control device 12. In this way, the on-board control device 12 appears to be composed of one housing, but includes boards for on-board control devices that function as on-board control devices in the number corresponding to the number of redundant transmission systems. In the example of Figure 2, the on-board control device 12 has two systems, i.e., two boards for on-board control devices that function as on-board control devices, so two MAC addresses are set for the on-board control device 12 during the manufacturing stage.

[0014] In this way, the train 10 is provided with an on-board control device for System 1 and an on-board control device for System 2, more specifically, a board that functions as the on-board control device for System 1 and a board that functions as the on-board control device for System 2, in each of the leading and trailing cars that are specified for a redundant transmission system. Also, the identification information is a MAC address unique to each board that functions as an on-board control device.

[0015] The train information management devices 13 and 14 are mounted on prescribed vehicles in a train 10 having a redundant transmission system (not shown). For example, if the right side in Fig. 2 is the direction of travel of the train 10, the train information management device 13 is mounted on the lead vehicle of the train 10 as a prescribed vehicle, and the train information management device 14 is mounted on the rear vehicle of the train 10 as a prescribed vehicle. If the left side in Fig. 2 is the direction of travel of the train 10, the train information management device 13 is mounted on the rear vehicle of the train 10 as a prescribed vehicle, and the train information management device 14 is mounted on the lead vehicle of the train 10 as a prescribed vehicle.

[0016] The train information management device 13 collects the MAC addresses, which are the above-mentioned identification information, from the on-board control device 11. Specifically, the train information management device 13 acquires the MAC addresses set on each board for the on-board control device, i.e., two MAC addresses, from the on-board control device 11. Similarly, the train information management device 14 collects the MAC addresses, which are the above-mentioned identification information, from the on-board control device 12. Specifically, the train information management device 14 acquires the MAC addresses set on each board for the on-board control device, i.e., two MAC addresses, from the on-board control device 12. Here, the train information management device 14 outputs the information of the two MAC addresses collected from the on-board control device 12 to the train information management device 13 of the vehicle on which the wireless on-board station 15 is mounted.

[0017] The radio on-board station 15 is mounted on one of the vehicles specified in the train 10 having a redundant transmission system (not shown). In this embodiment, the radio on-board station 15 is mounted on a vehicle on which the on-board control device 11 and the train information management device 13 are mounted. The radio on-board station 15 acquires the MAC address set on each board for the on-board control device, which is the above-mentioned identification information, from the train information management device 13, which is the first train information management device mounted on the same vehicle. Specifically, the radio on-board station 15 acquires the MAC address, which is the identification information, directly from the train information management device 13, which is the first train information management device mounted on the same vehicle, and acquires the MAC address, which is the identification information, from the train information management device 14, which is the second train information management device mounted on a different vehicle, via the train information management device 13, which is the first train information management device. The radio on-board station 15 transmits a total of four MAC addresses, consisting of two MAC addresses set in the on-board control device 11 obtained directly from the train information control device 13 and two MAC addresses set in the on-board control device 12 obtained indirectly from the train information control device 14 via the train information control device 13, as a combination of identification information, i.e., a combination of MAC addresses, to the ground-based radio terrestrial base station 31 via the on-board antenna 16. The combination of MAC addresses is a combination of the four combinations of MAC addresses.

[0018] On the ground, the wireless ground base station 31 receives the MAC address combination transmitted from the wireless on-board station 15 of the train 10 via the on-board antenna 16 via the ground antenna 30. The wireless ground base station 31 outputs the received MAC address combination to the ground control device 32 via the ground network 34. If the received MAC address combination contains noise or the like and the received signal is in such a state that the contents of the MAC address combination cannot be read, the wireless ground base station 31 may discard the received MAC address combination and not output it to the ground control device 32. The ground network 34 is, for example, an Internet line, a dedicated wired line, etc., but is not limited to these. The ground network 34 may be configured such that a part of it is composed of a wireless communication line and the remaining part is composed of the above-mentioned Internet line or a dedicated wired line.

[0019] The ground control device 32 uses the MAC address combination to search a database in which the correspondence between the MAC address combination and the train formation number of the train 10 is registered. Here, the ground control device 32 holds a database in which the correspondence between the MAC address combination set in the on-board control devices 11, 12 mounted on the train 10 and the train formation number of the train 10 on which the on-board control devices 11, 12 are mounted is registered when the train 10 is manufactured, etc. For example, the ground control device 32 receives the MAC address combination and the train formation number of the train 10 from the ground terminal 33 via the ground network 34 and holds the information in the database. The ground control device 32 may receive the MAC address combination and the train formation number of the train 10 from the ground terminal 33 not only when the train 10 is manufactured, but also when the on-board control devices 11, 12 are removed from the train 10 for maintenance inspection of the train 10 and different on-board control devices 11, 12 are mounted. The ground terminal 33 is a terminal device such as a personal computer or tablet operated by a person in charge of the railway company that operates the train 10.

[0020] FIG. 3 is a diagram showing a database held by the ground control device 32 in the wireless train control system 40 according to the present embodiment and a state of a search process of the ground control device 32. The ground control device 32 holds a database in which correspondence between MAC address combinations and train formation numbers of the train 10 is registered, as shown on the left side of FIG. 3. At this time, when the ground control device 32 acquires a MAC address combination as shown on the right side of FIG. 3 from the wireless ground base station 31, it searches the database using the acquired MAC address combination. In the example of FIG. 3, the ground control device 32 can obtain the train formation number #01 as a search result because a MAC address combination corresponding to the acquired MAC address combination exists in the database and the train formation number #01 is registered for the MAC address combination. For example, in the database shown on the left side of FIG. 3, if the train formation number #01 is for the train 10a shown in FIG. 1 and the train formation number #02 is for the train 10b shown in FIG. 1, the train 10a can acquire the train formation number #01 from the ground control device 32 by transmitting the MAC address combination shown on the right side of FIG. 3.

[0021] The ground control device 32 performs control to transmit the search results obtained by searching the database to the train 10 via the wireless ground base station 31. The ground control device 32 searches the database using the MAC address combination as described above, and when information on the train formation number is obtained, performs control to transmit the information on the train formation number as the search result. On the other hand, when the ground control device 32 searches the database using the MAC address combination, but there is no MAC address combination in the database that matches the MAC address combination used in the search, that is, when there is no train formation number corresponding to the MAC address combination, the ground control device 32 performs control to transmit a notification that there is no train formation number that matches the MAC address combination as the search result.

[0022] Although the above description has been given of a case where the ground control device 32 holds a database in which the correspondence between MAC address combinations and train formation numbers of the train 10 is registered, the present invention is not limited to this. The database in which the correspondence between MAC address combinations and train formation numbers of the train 10 is registered may be held by a configuration other than the ground control device 32. In this case, the ground control device 32 searches an external database via the ground network 34 using the MAC address combination.

[0023] The ground terminal 33 accepts operations from personnel of the railway company operating the train 10, and performs new registrations and changes to registered contents in a database in which correspondence between MAC address combinations and train 10 formation numbers is registered when the train 10 is manufactured, when the train 10 is maintained or inspected, etc.

[0024] Next, a description will be given of the operation of each device when the on-board control devices 11, 12 of the train 10 acquire information on the formation number in the radio train control system 40. Fig. 4 is a flowchart showing the operation of each device when the on-board control devices 11, 12 of the train 10 acquire information on the formation number in the radio train control system 40 according to this embodiment.

[0025] First, when the train 10 is newly manufactured, or when the on-board control devices 11, 12 mounted on the train 10 are changed during maintenance and inspection of the train 10 in operation, a person in charge of the railway company that operates the train 10 registers the correspondence between the MAC address combination and the train formation number of the train 10 in the database of the ground control device 32. That is, the ground control device 32 accepts registration of the correspondence between the MAC address combination and the train formation number of the train 10 in the database it holds (step S1).

[0026] When train 10 starts operating, that is, when power is turned on in train 10, train information management device 13 collects the MAC address set in on-board control device 11 from on-board control device 11. Also, train information management device 14 collects the MAC address set in on-board control device 12 from on-board control device 12 (step S2). In this embodiment, train information management device 13 collects two MAC addresses from on-board control device 11, and train information management device 14 collects two MAC addresses from on-board control device 12.

[0027] The train information management devices 13 and 14 aggregate the collected MAC addresses (step S3). As described above, the train information management device 14 outputs the two MAC addresses collected from the on-board control device 12 to the train information management device 13 of the vehicle on which the wireless on-board station 15 is mounted. The train information management device 13 obtains the two MAC addresses from the train information management device 14.

[0028] The wireless on-board station 15 acquires the four MAC addresses from the train information management device 13, and transmits the acquired four MAC addresses as a combination of MAC addresses to the wireless ground base station 31 on the ground via the on-board antenna 16 (step S4).

[0029] On the ground, the wireless ground base station 31 receives, via the ground antenna 30, the MAC address combination transmitted from the wireless on-board station 15 of the train 10 via the on-board antenna 16 (step S5). The wireless ground base station 31 outputs the received MAC address combination to the ground control device 32 via the ground network 34.

[0030] The ground control device 32 uses the MAC address combination acquired from the wireless ground base station 31 to search a database in which the correspondence between the MAC address combination and the train formation number of the train 10 is registered (step S6). The ground control device 32 outputs the search result to the wireless ground base station 31.

[0031] The wireless ground base station 31 transmits the search result acquired from the ground control device 32 to the train 10 via the ground antenna 30 (step S7).

[0032] In the train 10, the radio on-board station 15 receives the search result via the on-board antenna 16 (step S8). The radio on-board station 15 outputs the received search result to the train information management device 13. The train information management device 13 notifies the train information management device 14 and the on-board control device 11 of the acquired search result. The train information management device 14 notifies the on-board control device 12 of the acquired search result.

[0033] The on-board control devices 11, 12 perform control on the train 10 based on the acquired search results. Specifically, when the on-board control devices 11, 12 acquire a train set number as the search result (step S9: Yes), they perform control to run the train 10 (step S10). That is, the on-board control devices 11, 12 normally start up when the train 10 starts to run, that is, when the power is turned on in the train 10. When the search result is a notification that there is no train set number that matches the combination of MAC addresses transmitted from the wireless on-board station 15 (step S9: No), the on-board control devices 11, 12 perform control not to run the train 10 (step S11). For example, the on-board control devices 11, 12 perform control such as applying an emergency brake to stop the train 10 from moving.

[0034] Here, when the search result acquired by the on-board control devices 11 and 12 is a notification that there is no train formation number that matches the combination of MAC addresses (step S9: No), the following two patterns are actually considered. The first pattern is a case where the train 10 is newly manufactured, and the correspondence between the combination of the MAC addresses of the on-board control devices 11 and 12 and the train formation number of the train 10 has not been registered in the database by a person in charge of the railway company or the like. The second pattern is a case where the train 10 has been subjected to maintenance and inspection, and the on-board control devices 11 and 12 mounted on the train 10 have been replaced, but the registered contents of the database have not been updated by a person in charge of the railway company or the like. Therefore, when the search result is a notification that there is no train formation number that matches the combination of MAC addresses transmitted from the wireless on-board station 15 (step S9: No), the on-board control devices 11 and 12 perform control not to run the train 10 (step S11), and may display a message on a monitor device (not shown) installed in the cab of the train 10 to prompt the driver of the train 10 to check the registered contents of the database.

[0035] Next, a hardware configuration of the radio train control system 40 according to the present embodiment will be described. In the radio train control system 40, the radio on-board station 15 and the radio ground base station 31 are communication devices. The on-board antenna 16 and the ground antenna 30 are antenna elements. The ground terminal 33 is a terminal device such as a personal computer or a tablet. The on-board control devices 11 and 12, the train information management devices 13 and 14, and the ground control device 32 are realized by processing circuits. 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. 5 is a diagram showing an example of the configuration of the processing circuit 90 in the case where the processing circuit of the radio train control system 40 according to the present embodiment is realized by a processor 91 and a memory 92. The processing circuit 90 shown in FIG. 5 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 described as a program and stored in the memory 92. In the processing circuit 90, each function is realized by the processor 91 reading and executing the program stored in the memory 92. That is, the processing circuit 90 includes a memory 92 for storing a program that results in the processing of the radio train control system 40 being executed. This program can also be said to be a program for causing the radio train control system 40 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.

[0037] The above program can also be said to be a program that causes the wireless train control system 40 to execute the following steps: a first step in which the train information management devices 13, 14 collect identification information from the on-board control devices 11, 12 that are mounted on specified cars in the train 10 having redundant transmission systems and that have identification information set for communicating with either of the transmission systems; a second step in which the radio on-board station 15 acquires the identification information from the train information management devices 13, 14 and transmits a combination of the identification information; a third step in which the wireless ground base station 31 receives the combination of the identification information; a fourth step in which the ground control device 32 uses the combination of the identification information to search a database in which correspondence between the combination of the identification information and the train formation number of the train 10 is registered and controls the transmission of the search result to the train 10 via the wireless ground base station 31; a fifth step in which the train information management devices 13, 14 acquire the search result via the radio on-board station 15 and notify the on-board control devices 11, 12 of the search result; and a sixth step in which the on-board control devices 11, 12 perform control based on the acquired search result.

[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. Also, 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), an EEPROM (Electrically EPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD (Digital Versatile Disc), etc.

[0039] Fig. 6 is a diagram showing an example of the configuration of the processing circuit 93 in the case where the processing circuit of the radio train control system 40 according to this embodiment is realized by dedicated hardware. The processing circuit 93 shown in Fig. 6 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 of these. The processing circuit 93 may be partially realized by dedicated hardware and partially realized by software or firmware. In this way, the processing circuit 93 can realize each of the above-mentioned functions by dedicated hardware, software, firmware, or a combination of these.

[0040] As described above, according to this embodiment, in the radio train control system 40, the train information management devices 13 and 14 of the train 10 collect the MAC addresses set in the on-board control devices 11 and 12 from the on-board control devices 11 and 12, and the radio on-board station 15 transmits the MAC address combination to the ground control device 32. The ground control device 32 uses the MAC address combination to search a database in which the correspondence between the MAC address combination and the train formation number of the train 10 is registered, and controls to transmit the search result to the train 10. When the on-board control devices 11 and 12 of the train 10 acquire the train formation number of the train 10 as the search result, they control to run the train 10. In this way, in the radio train control system 40, the on-board control devices 11 and 12 can acquire information on the train formation number of the train 10 mounted thereon, without changing the hardware according to the number of existing train formations, even if the number of trains 10 whose operation is controlled by the radio train control system 40 increases.

[0041] The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or the embodiments may be combined with each other. Also, parts of the configurations may be omitted or modified without departing from the spirit of the invention. [Explanation of symbols]
