[0028] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0030] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0031] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0032] In the embodiments disclosed herein, the collection, updating, analysis, processing, use, transmission, provision, disclosure, and storage of data (e.g., including but not limited to user personal information) comply with relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. In particular, necessary measures have been taken to prevent unauthorized access to user personal information data and to safeguard user personal information security, network security, and national security.

[0033] In the embodiments disclosed herein, user authorization or consent is obtained before acquiring or collecting user personal information.

[0034] Figure 1 The diagram illustrates a schematic representation of inter-train communication in related technologies.

[0035] like Figure 1 As shown, in related technologies, inter-train communication is achieved through physical connections of cross-car communication cables. Static formation refers to a train formation where the connection order of each car remains fixed over a long period. Dynamic formation refers to a train formation that can be adjusted according to actual operational needs. Inter-train communication can be achieved by physically connecting the Ethernet Train Backbone Network (ETBN) equipment and Passenger Information System (PIS) equipment within each train formation using communication cables. Communication within each train formation can be achieved by physically connecting repeater (REP) equipment using communication cables. During train operation, collisions and twists are unavoidable at communication cable connections, leading to wear and tear on the cables or connectors, and even communication failures. Furthermore, the coupling and uncoupling operations during train formation and maintenance are time-consuming. During peak and off-peak seasons or when passenger flow differs between peak and off-peak periods, trains need to flexibly adjust their dynamic formation to cope with passenger flow fluctuations and demands, thereby significantly improving the flexibility of train formation.

[0036] In view of this, embodiments of the present disclosure provide a communication system, method, train, device, and medium for train formations. This system not only changes the wired connection between train formations to a wireless connection, improving the flexibility and efficiency of train formations, but also improves the reliability of communication between train formations by setting up dual communication device redundancy, dual link redundancy, and wireless transmission module redundancy.

[0037] Figure 2 A schematic diagram of a communication system for train formations according to an embodiment of the present disclosure is shown. It should be noted that... Figure 2 The examples shown are merely examples of system architectures that can be applied to the embodiments of this disclosure, in order to help those skilled in the art understand the technical content of this disclosure, but do not mean that the embodiments of this disclosure cannot be used in other devices, systems, environments or scenarios.

[0038] like Figure 2As shown, the communication system 200 for train formations in this embodiment may include an information transmitting device 111, a first communication device 112 and a first transmission module 113 installed in the first train formation 110, and an information receiving device 121, a second communication device 122 and a second transmission module 123 installed in the second train formation 120.

[0039] In some embodiments, the information transmitting device 111 can be used to transmit train operation information from the train control system to the first communication device 112. The first communication device 112 can be used to encapsulate the received operation information into first information. The operation information sent by the train control system to the first trainset 110 can be transmitted via wired or wireless connection. The operation information may include real-time information and control command information during train operation. The information transmitting device 111, the first communication device 112, and the first transmission module 113 within the first trainset 110 can communicate via a wired connection, such as a communication cable. The first information can be information that encapsulates the original operation information in the first communication device to ensure that it remains intact during transmission.

[0040] In some embodiments, the first transmission module 113 can be used to send first information from the first communication device 112 to the second transmission module 123. The second transmission module 123 is used to send the first information to the second communication device 122 configured within the second group 120. The first transmission module 113 and the second transmission module 123 are wirelessly connected. The first communication device 112 within the first group 110 and the second communication device 122 within the second group 120 can achieve wireless communication through the first transmission module 113 and the second transmission module 123.

[0041] In some embodiments, the second communication device 122 can be used to parse the received first information into operating information. The second communication device 122 can parse the first information encapsulated by the first communication device 112 to obtain the original information before encapsulation, i.e., the train's operating information. The information receiving device 121 can be used to receive the operating information from the second communication device 122 to synchronize the operating information of the second trainset 120 with that of the first trainset 110. The information receiving device 121, the second communication device 122, and the second transmission module 123 within the second trainset 120 can achieve communication functions through a wired connection, such as a communication cable.

[0042] It should be understood that Figure 2 The number of groups, devices, and modules shown is merely illustrative. The number of groups, devices, and modules can be increased or decreased according to the actual application scenario.

[0043] According to embodiments of this disclosure, a first communication device installed in a first train formation and a second communication device installed in a second train formation achieve synchronization of train operation information through a first transmission module and a second transmission module connected wirelessly. This changes the wired connection between train formations to a wireless connection, which not only reduces the wiring cost of the train and reduces communication failures caused by damaged connection cables, but also improves the flexibility and efficiency of train formation.

[0044] Figure 3 A schematic diagram of a communication system for train formations according to another embodiment of the present disclosure is shown.

[0045] like Figure 3 As shown, another embodiment of the communication system 300 may include a third communication device 114 and a fourth communication device 124. The third communication device 114 may be located within the first group 110, serving as a backup for the first communication device 112. The third communication device 114 may be used to encapsulate operational information from the information sending device 111 to obtain second information and send it to the first transmission module 113. The fourth communication device 124 may be located within the second group 120, serving as a backup for the second communication device 122. The fourth communication device 124 may be used to parse the second information from the second transmission module 123 to obtain operational information and send it to the information receiving device 121, thereby synchronizing the operational information of the second group 120 with that of the first group 110.

[0046] According to embodiments of this disclosure, dual communication devices are used in the first and second train sets to achieve equipment redundancy and replace wired connections between train sets, thereby improving the flexibility between train sets and the reliability of communication methods.

[0047] Figure 4 An internal network topology diagram of a first communication device according to an embodiment of the present disclosure is illustrated schematically.

[0048] like Figure 4As shown, operational information can be divided into two types based on service type: Type 1 information and Type 2 information. Type 1 information can be Ethernet Train Backbone Network (ETBN) information, including control command information, equipment status information, and equipment operation and maintenance information conforming to the IEC 61375 protocol, such as traction and braking command information, door opening and closing information, air conditioning start / stop information, motor temperature information, axle speed information, and link status information. Type 2 information can be Passenger Information System (PIS) information, which can include important information fed back to passengers, such as train speed, carriage temperature, arrival time, direction of travel, stop time, and emergency information. The first communication device can include a first link and a second link. The first link can be used to encapsulate Type 1 information received from the information transmitting device through a first interface into first encapsulated information, and send the first encapsulated information to the first transmission module through a third interface. The second link can be used to encapsulate Type 2 information received from the information transmitting device through a second interface into second encapsulated information, and send the second encapsulated information to the first transmission module through a fourth interface.

[0049] In some embodiments, the first link and the second link can be wired Ethernet connection channels with a transmission rate of gigabit speeds.

[0050] In some embodiments, the first interface may be a wired interface configured to receive a first type of information on the first communication device; the third interface may be a wired interface configured to send first encapsulation information on the first communication device. The second interface may be a wired interface configured to receive a second type of information on the first communication device; the third interface may be a wired interface configured to send second encapsulation information on the first communication device.

[0051] The first communication device may also include other interfaces for configuring and managing the device. Users can log in to the device through these other interfaces to perform initial configuration, troubleshooting, and device maintenance.

[0052] In some embodiments, the first communication device may further include a first bridging component and a first tunneling component. The first bridging component can use bridging technology to transmit first type information and second type information from a first interface and a second interface to the first communication device. The first tunneling component can use tunneling technology to encapsulate the first type information and second type information to obtain first encapsulated information and second encapsulated information. Using the first bridging component and the first tunneling component, they work together to send the original wired operation information (wireless data) to the first communication device connected to the first transmission module, and can also use wireless communication to send it to the second communication device of the second train formation at the other end. By using bridging and tunneling technologies, transparent data transmission between communication devices is achieved, making the devices unaware of changes in the physical link, thereby ensuring compatibility with all specifications of existing wired train communication networks and achieving cost-free switching from wired to wireless connections.

[0053] It should be noted that since the third communication device is a backup device for the first communication device, their internal network topologies are the same. The links within the third communication device can be described by referring to the internal network topology of the first communication device.

[0054] Within the first train carriage, the third communication equipment may include a third link and a fourth link. The third link may be used to encapsulate first-type information from the information transmitting device into third-encapsulated information and send the third-encapsulated information to the first transmission module. The fourth link may be used to encapsulate second-type information from the information transmitting device into fourth-encapsulated information and send the fourth-encapsulated information to the first transmission module.

[0055] In some embodiments, the third and fourth links can be wired Ethernet connection channels with a transmission rate of gigabit speeds.

[0056] Combination Figure 4 The third communication device may include a first bridging component and a first tunneling component. The first bridging component can use bridging technology to send first type information and second type information to the third communication device. The first tunneling component can use tunneling technology to encapsulate the first type information and second type information to obtain third encapsulated information and fourth encapsulated information.

[0057] According to embodiments of this disclosure, two wired links are respectively set up within the first and third communication devices. First type data and second type data each have two links to achieve link redundancy. First type information and type information can be sent from the two links according to a strategy. If one communication device fails, the information will be centrally sent from the other link. This link redundancy, based on the load sharing and mutual backup of the first and third communication devices, can further improve the reliability of communication between train formations.

[0058] Figure 5 A schematic diagram of a communication system for train formations according to another embodiment of the present disclosure is shown.

[0059] Combination Figure 4 and Figure 5 As shown, the information transmitting device 111 in this embodiment may include a first transmitting device 111-1 and a second transmitting device 111-2. The first transmitting device 111-1 can be used to transmit first-type information from the train control system to a first link of a first communication device 112 and a third link of a third communication device 114, respectively. The second transmitting device 111-2 is used to transmit second-type information from the train control system to a second link of the first communication device 112 and a fourth link of the third communication device 114, respectively. The first transmitting device 111-1 and the second transmitting device 111-2 achieve dual-link redundancy backup through static link aggregation.

[0060] In some embodiments, the first transmission module 113 may include a first transmission unit 113-1 and a second transmission unit 113-2. The first transmission unit 113-1 may be used to send first encapsulation information from the first communication device 112 and third encapsulation information from the third communication device 114 to the second transmission module 123. The second transmission unit 113-2 may be used to send second encapsulation information from the first communication device 112 and fourth encapsulation information from the third communication device 114 to the second transmission module 123.

[0061] In some embodiments, the first transmission unit 113-1 and the second transmission unit 113-2 may include any one of a wireless communication module such as a StarSignal module or a Wi-Fi 7 module. The StarSignal module has the advantages of low latency and high reliability, while the Wi-Fi 7 module has the advantages of high speed and large bandwidth.

[0062] According to embodiments of this disclosure, the first communication device and the third communication device employ a dual-link and dual-transmission-unit design to achieve link redundancy and transmission unit redundancy, thereby further improving communication reliability.

[0063] Figure 6 An internal network topology diagram of a second communication device according to an embodiment of the present disclosure is illustrated schematically.

[0064] like Figure 6As shown, the second communication device in this embodiment may include a fifth link and a sixth link. The fifth link can be used to parse the first encapsulation information received from the second transmission module through the fifth interface into first type information, and send the first type information to the information receiving device through the seventh interface. The sixth link can be used to parse the second encapsulation information received from the second transmission module through the fifth interface into second type information, and send the second type information to the information receiving device through the eighth interface.

[0067] The second communication device may also include other interfaces for configuring and managing the device. Users can log in to the device through these other interfaces to perform initial configuration, troubleshooting, and device maintenance.

[0068] In some embodiments, the second communication device may further include a second bridging component and a second tunneling component. The second tunneling component can use tunneling technology to parse the first encapsulation information and the second encapsulation information to obtain first type information and second type information. The second bridging component can use bridging technology to transmit the first type information and the second type information from the second communication device to the seventh interface and the eighth interface. Using the second bridging component and the second tunneling component, they work together to parse the encapsulated operational information and send it to the information receiving device to synchronize the operational information between the second group and the first group.

[0069] It should be noted that since the fourth communication device is a backup device for the second communication device, their internal network topologies are the same. The links within the fourth communication device can be described by referring to the internal network topology of the second communication device.

[0070] Within the second train carriage, the fourth communication device may include a seventh link and an eighth link. The seventh link can be used to parse the first encapsulated information from the second transmission module into first type information and send the first type information to the information receiving device. The eighth link can be used to parse the second encapsulated information from the second transmission module into second type information and send the second type information to the information receiving device.

[0071] In some embodiments, the seventh and eighth links can be wired Ethernet connection channels with a transmission rate of gigabit speeds.

[0072] Combination Figure 6 The fourth communication device may include a second bridging component and a second tunneling component. The second tunneling component can use tunneling technology to parse the first encapsulation information and the second encapsulation information to obtain first type information and second type information. The second bridging component can use bridging technology to transmit the first type information and the second type information from the second communication device to the seventh interface and the eighth interface.

[0073] According to embodiments of this disclosure, two wired links are respectively set inside the second communication device and the fourth communication device. The first encapsulated data and the second encapsulated data each have two links to achieve link redundancy. The link redundancy based on the equipment redundancy of load sharing and mutual backup between the second and fourth communication devices can further improve the reliability of communication between train formations.

[0074] Continue to refer to Figure 5 The second transmission module 123 may include a third transmission unit 123-1 and a fourth transmission unit 123-2. The third transmission unit 123-1 can be used to send first encapsulation information from the first transmission unit 113-1 to the second communication device 122, and to send third encapsulation information from the first transmission unit 113-1 to the fourth communication device 124.

The first receiving device 121-1 can be used to receive first-type information from the second communication device 122 and the fourth communication device 124 to synchronize the first-type information of the second group with that of the first group. The second receiving device 121-2 can be used to receive second-type information from the second communication device 122 and the fourth communication device 124 to synchronize the second-type information of the second group with that of the first group.

[0078] Figure 7 This diagram schematically illustrates the communication process between carriages within a train formation according to an embodiment of the present disclosure. It should be noted that... Figure 7 The number of train sets, carriages, and equipment shown is merely illustrative. The number of train sets, carriages, and equipment can be increased or decreased according to the actual application scenario.

[0079] like Figure 7 As shown, both the first and second train sets may include at least one carriage. The communication system in this embodiment may also include a first relay device REP1 and a second relay device REP2.

[0080] A first relay device REP1 can be installed in at least one car within the first train set, used to transmit first-type information from a first transmitting device (illustrated as ETBN1) to a first communication device, and second-type information from a second transmitting device (illustrated as PIS1) to a third communication device, thereby enabling the transmission of first-type and second-type information between at least one car within the first train set.

[0085] When operating S810, train operation information is received from the train control system via the information transmission equipment within the first train group.

[0086] During operation of S820, the first communication device in the first group encapsulates the operating information from the information sending device to obtain the first information.

[0087] In operation S830, the first information from the first communication device in the first transmission module of the first train group is sent to the second transmission module in the second train group, and the first transmission module and the second transmission module are wirelessly connected.

[0088] During operation of S840, the first information from the second transmission module is parsed into operation information through the second communication device in the second group.

[0089] During operation of S850, the operating information from the second communication device is received through the information receiving device in the second group to synchronize the operating information of the second group with that of the first group.

[0090] According to embodiments of this disclosure, a first communication device installed in a first train formation and a second communication device installed in a second train formation achieve synchronization of train operation information through a first transmission module and a second transmission module connected wirelessly. This changes the wired connection between train formations to a wireless connection, which not only reduces the wiring cost of the train and reduces communication failures caused by damaged connection cables, but also improves the flexibility and efficiency of train formation.

[0091] This disclosure also provides a train, including the aforementioned communication system configured on the train. By utilizing the static link aggregation function of the information transmitting and receiving equipment and the redundancy of dual communication equipment within the trainset to replace the wired connection between trainsets, the purpose of equipment redundancy and link redundancy is achieved to meet the reliability requirements of train communication. The communication equipment adopts a dual-link and dual-transmission unit design to achieve link redundancy and module redundancy, further improving the reliability of train communication. The communication equipment employs bridging and tunneling technologies to achieve transparent data transmission between devices, making the devices unaware of physical changes in the link, thereby ensuring compatibility with all specifications of existing wired train communication networks and achieving cost-free switching from wired to wireless connections.
