Description

Technical Field

[0001] This disclosure relates to the field of trains, and further to the field of rail transit train reconfiguration, and particularly to a wireless-based vehicle reconfiguration information calculation method, device, and train. Background Technology

[0002] Currently, urban rail transit is characterized by significant variations in passenger flow across different time periods. However, urban rail transit systems mostly use fixed-formation trains, making it difficult to flexibly adjust the number of trains to meet varying capacity demands. Train coupling / decoupling allows for flexible changes in train formation, balancing operational service levels and train occupancy rates. This addresses the problem of wasted capacity due to uneven time distribution, meets capacity requirements at different times, and improves transportation economics.

[0003] However, when trains are coupled or decoupled, the relationships between different train formations will change significantly. In this scenario, it is impossible to automatically identify the formation relationships and order. Therefore, a wireless-based method for calculating vehicle reconfiguration information is proposed to facilitate quick and accurate identification of formation relationships and order. Summary of the Invention

[0004] This disclosure provides a wireless-based vehicle reconfiguration information calculation method, device, and train, which solves the technical problem that trains from different manufacturers cannot be freely assembled and disassembled.

[0005] According to a first aspect of this disclosure, a wireless-based method for calculating vehicle reconfiguration information is provided. The method includes:

[0006] After the terminal device is powered on and initialized, it monitors the status of the associated wireless devices in real time. If it continuously detects that the terminal device is associated with other wireless devices, it sends multicast data carrying the terminal device's own number and receives multicast data carrying its own number sent by terminal devices in other carriages to establish and confirm the connection relationship between carriages, and sends multicast data carrying the connection relationship order of the carriages.

[0007] The train head or train tail equipment collects and summarizes multicast data sent by the terminal equipment of all carriages, carrying the order of the connection relationship between the carriages, to obtain the connection relationship data between all carriages. The connection relationship data is then filled into the initial connection relationship data packet. The train head or train tail equipment then sends the initial connection relationship data packet it has summarized to the corresponding peer.

[0008] After the receiving initial connection relationship data packet is compared with the initial connection relationship data packet it has summarized, the train head end or train tail end device obtains a connection relationship comparison success data packet carrying the terminal device number, and sends the connection relationship comparison success data packet to the corresponding peer end respectively.

[0009] After receiving the connection relationship comparison success data packet sent by the other end, the equipment at the head end or tail end of the train compares it with its own equipment number to confirm, obtains the final equipment connection relationship data packet, and sends it to the terminal equipment in all carriages.

[0010] In addition to the aspects and any possible implementations described above, a further implementation is provided in which, after the terminal device is powered on and initialized, it monitors the status of associated wireless devices in real time. If other associated wireless devices are continuously detected, it sends multicast data carrying the terminal device's own identifier, including:

[0011] After the terminal device performs power-on initialization, it monitors the status of the associated wireless devices in real time. If it continuously detects that the terminal device is associated with other wireless devices and there is only one associated wireless device, it determines that the terminal device is a train head end or train tail end device, fills the device number of the terminal device into the reporting number data packet, and sends multicast data carrying the terminal device's own number.

[0012] If it is continuously detected that the terminal device is associated with other wireless devices, and there are two associated wireless devices, then the terminal device is determined to be a normal terminal device, and the device number of the terminal device is filled into the reporting number data packet, and multicast data carrying the terminal device's own number is sent.

[0013] In addition to the aspects and any possible implementations described above, a further implementation is provided, wherein receiving multicast data carrying its own identifier sent by terminal devices in other carriages to establish and confirm the connection relationship between carriages, and sending multicast data carrying the order of the connection relationship between the carriages includes:

[0014] If the terminal device is a device at the head or tail of the train, after receiving multicast data carrying its own number sent by terminal devices in other carriages, it will be sorted in the order of the device number of the terminal device first, followed by the device numbers of adjacent terminal devices.

[0015] If the terminal device is a regular terminal device, after receiving multicast data carrying its own number sent by the terminal devices in other carriages, the data is sorted according to the device number of the terminal device being centered, with the device numbers of two adjacent terminal devices placed before and after the device numbers of the terminal devices respectively.

[0016] After obtaining the connection relationship between the carriages, the terminal device fills the connection relationship into the reporting device connection relationship data packet and sends out the reporting device connection relationship data packet carrying the order of the connection relationship between the carriages.

[0017] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the train-head or train-tail device collects and summarizes multicast data carrying the order of connection relationships between all carriages sent by the terminal devices of all carriages, obtains connection relationship data between all carriages, fills the connection relationship data into an initial version of the connection relationship data packet, and the train-head or train-tail device respectively sends the initial version of the connection relationship data packet it has summarized to the corresponding peer, including:

[0018] The train head-end or train tail-end equipment summarizes the connection relationships based on the connection relationship data packet from the reporting equipment, obtains the connection relationship data between all carriages, fills the connection relationship data into the initial connection relationship data packet, and sends it to the terminal equipment in all carriages in the form of multicast data; wherein...

[0019] After receiving the initial device connection relationship data packet, the ordinary terminal device does not change the content of the packet, but retransmits it in the form of multicast data.

[0020] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the train head-end or train tail-end device performs a reverse comparison between the received initial connection relationship data packet and its own summarized initial connection relationship data packet to obtain a connection relationship comparison success data packet carrying the terminal device number, and sends the connection relationship comparison success data packet to the corresponding peer end, including:

[0021] If the comparison results are the same, a connection relationship comparison success data packet is sent. After receiving the connection relationship comparison success data packet sent by the other end, the equipment at the head end or tail end of the train compares it with its own equipment number to confirm and obtain the final version of the equipment connection relationship data packet, and sends it to the terminal equipment in all carriages.

[0022] If the comparison results are different, a connection relationship comparison failure data packet is sent, and the calculated device connection relationship is cleared and a new device connection relationship calculation process is started.

[0023] In addition to the aspects and any possible implementations described above, a further implementation is provided in which, after receiving the connection relationship comparison success data packet sent by the other end, the train head-end or train tail-end device compares and confirms it with its own device number to obtain the final device connection relationship data packet, and sends it to the terminal devices in all carriages, including:

[0024] After receiving the connection comparison success data packet sent by the other end, the equipment at the head or tail of the train takes the terminal device with the smaller number as the starting point, stores only the device connection relationship table starting with that number, fills the device connection relationship table into the final version of the device connection relationship data packet, and sends it to the terminal devices in all carriages; wherein...

[0025] After receiving the final version of the device connection relationship data packet, the ordinary terminal device parses out and stores the device connection relationship, and without changing the content of the packet, sends it again in the form of multicast data. Finally, the data packet will be sent to all terminal devices on the train.

[0026] According to a second aspect of this disclosure, a wireless-based vehicle reconfiguration information computing device is provided. The device includes:

[0027] The status monitoring module is used to monitor the status of associated wireless devices in real time after the terminal device is powered on and initialized. If it is continuously detected that the terminal device is associated with other wireless devices, it sends multicast data carrying the terminal device's own number and receives multicast data carrying its own number sent by terminal devices in other carriages to establish and confirm the connection relationship between carriages, and sends multicast data carrying the connection relationship order of the carriages.

[0028] The collection and aggregation module is used by the train head end or train tail end equipment to collect and aggregate multicast data sent by the terminal equipment of all carriages, carrying the order of the connection relationship between the carriages, to obtain the connection relationship data between all carriages, and to fill the connection relationship data into the initial connection relationship data packet. The train head end or train tail end equipment respectively sends the initial connection relationship data packet obtained by itself to the corresponding peer end.

[0029] The reverse comparison module is used by the train head end or train tail end device to perform a reverse comparison and confirmation on the received initial connection relationship data packet and the initial connection relationship data packet it has summarized, and then obtains a connection relationship comparison success data packet carrying the terminal device number, and sends the connection relationship comparison success data packet to the corresponding peer end respectively.

[0030] The confirmation and reporting module is used to compare the connection relationship comparison success data packet sent by the other end with its own device number after the device at the front or rear of the train receives the connection relationship comparison success data packet sent by the other end, obtain the final device connection relationship data packet, and send it to the terminal devices in all carriages.

[0031] According to a third aspect of this disclosure, a train is provided in which each carriage is equipped with a wireless vehicle reconfiguration information computing device as described above:

[0032] One terminal device and one wireless device are installed in each train carriage, wherein the terminal device is associated with the wireless device, and the wireless device uses a directional antenna.

[0033] According to a fourth aspect of this disclosure, an electronic device is provided. The electronic device includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described above.

[0034] According to a fifth aspect of this disclosure, a computer-readable storage medium is provided having a computer program stored thereon that, when executed by a processor, implements the methods as described in the first and / or second aspects of this disclosure.

[0035] In the embodiments of this disclosure, after the terminal device is powered on and initialized, the status of the associated wireless devices can be monitored in real time. If other wireless devices are continuously detected, multicast data is sent and multicast data sent by other terminal devices is received to confirm the connection relationship between carriages, and the connection relationship is sent out. The head or tail end device of the train collects and summarizes all multicast data, fills the data into the initial version of the connection relationship data packet, and sends the initial version of the connection relationship data packet it has summarized to the corresponding peer end. The peer end performs a reverse comparison between the received initial version of the connection relationship data packet and its own summary to confirm, and then obtains a connection relationship comparison success data packet and sends it out. After receiving the connection relationship comparison success data packet sent by the peer end, the head or tail end device of the train compares it with its own device number to confirm, obtains the final version of the device connection relationship data packet, and sends it to the terminal devices of all carriages. In this way, there is no need to consider the interface compatibility between different manufacturers. The flexible grouping of different train carriages from different manufacturers can be achieved by deploying wireless equipment. This solves the problem of wasted transport capacity caused by uneven time distribution, meets the transport capacity requirements at different times, improves transport economy, realizes real-time acquisition of grouping relationships and order, and is simple to operate and easy to maintain.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0043] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist.

This solves the problem of wasted transport capacity caused by uneven time distribution, meets the transport capacity requirements at different times, improves transport economy, realizes real-time acquisition of grouping relationships and order, and is simple to operate and easy to maintain.

[0045] The following detailed description, with reference to the accompanying drawings and specific embodiments, illustrates a wireless-based vehicle reconfiguration information calculation method, apparatus, and train provided in this disclosure.

[0046] Figure 1 A structural diagram of a train equipped with a wireless vehicle reconfiguration information computing device, as provided in an embodiment of this disclosure, is shown. Figure 1 As shown, a train equipped with a wireless vehicle reconfiguration information computing device may include:

[0047] One terminal device and one wireless device are installed in each train carriage, wherein the terminal device is associated with the wireless device, and the wireless device uses a directional antenna.

[0048] In some embodiments, a terminal device is installed in each carriage of the train formation, and the terminal device has a unique number on the line. This terminal device is connected to a wireless device via an Ethernet interface. Considering the length of the carriage, a low-power UWB wireless device is selected, and a directional antenna is used so that the wireless signal in the carriages other than the front and rear carriages can only cover both ends of the carriage and can only communicate wirelessly with the two carriages in front and behind. The wireless signal at the front and rear of the train can only cover the interior of the train. Among them, UWB technology has the characteristics of simple system structure, high transmission rate, low power consumption, simple engineering and low cost.

[0049] Figure 2 A flowchart illustrating a wireless-based vehicle reconfiguration information calculation method provided by an embodiment of this disclosure is shown, such as... Figure 2 As shown, a wireless-based vehicle reassembly information calculation method 200 may include the following steps:

[0050] S210, after the terminal device is powered on and initialized, it monitors the status of the associated wireless devices in real time. If it continuously detects that the terminal device is associated with other wireless devices, it sends multicast data carrying the terminal device's own number and receives multicast data carrying its own number sent by terminal devices in other carriages to establish and confirm the connection relationship between carriages, and sends multicast data carrying the connection relationship order of the carriages.

[0051] In some embodiments, an automated system can be set up to initialize the terminal devices, including: the automated system first receives a regrouping instruction from the control center, parses the instruction to determine the specific operations to be performed, including which terminal devices need to be powered on and initialized, and then sends a power-on signal to the designated terminal devices. After receiving the power-on signal, the terminal devices start the internal power management module to perform the power-on operation. During the power-on process, the terminal devices will perform a series of self-checks and initialization operations to ensure that the devices are in normal working condition.

[0052] In some embodiments, after confirming the connection relationship, the terminal device can calculate and determine the connection order between carriages based on the received data (such as timestamps, signal strength, etc.) and generate multicast data containing the connection order of the carriage.

[0053] For example, after the terminal device performs power-on initialization, it monitors the status of the associated wireless devices in real time. If it continuously monitors that the terminal device is associated with other wireless devices and there is only one associated wireless device, it determines that the terminal device is a train head end or train tail end device, fills the device number of the terminal device into the reporting number data packet, and sends multicast data carrying the terminal device's own number.

[0054] If it is continuously detected that the terminal device is associated with other wireless devices, and there are two associated wireless devices, then the terminal device is determined to be a normal terminal device, and the device number of the terminal device is filled into the reporting number data packet, and multicast data carrying the terminal device's own number is sent.

[0055] For example, if the terminal device is a device at the head or tail of the train, after receiving multicast data carrying its own number sent by terminal devices in other carriages, it is sorted in such a way that the device number of the terminal device comes first, followed by the device number of the adjacent terminal devices.

[0056] If the terminal device is a regular terminal device, after receiving multicast data carrying its own number sent by the terminal devices in other carriages, the data is sorted according to the device number of the terminal device being centered, with the device numbers of two adjacent terminal devices placed before and after the device numbers of the terminal devices respectively.

[0057] After obtaining the connection relationship between the carriages, the terminal device fills the connection relationship into the reporting device connection relationship data packet and sends out the reporting device connection relationship data packet carrying the order of the connection relationship between the carriages.

[0058] S220, the train head end or train tail end device collects and summarizes the multicast data carrying the order of the connection relationship between the carriages sent by the terminal devices of all carriages, obtains the connection relationship data between all carriages, fills the connection relationship data into the initial version of the connection relationship data packet, and the train head end or train tail end device respectively sends the initial version of the connection relationship data packet obtained by itself to the corresponding peer end.

[0059] In some embodiments, during transmission, the device employs a reliable communication protocol, such as TCP / IP or a train-specific communication protocol, to ensure accurate data transmission to the other end. Simultaneously, to verify successful data transmission and reception, the device waits for an acknowledgment signal from the other end. Once the acknowledgment signal is received, the devices at the front and rear of the train can confirm that the entire train's connection data has been successfully synchronized at both ends, providing a solid foundation for subsequent information transmission and control system operation.

[0060] For example, the train head-end or train tail-end device summarizes the connection relationships based on the connection relationship data packet from the reporting device, obtains connection relationship data between all carriages, fills the connection relationship data into the initial connection relationship data packet, and sends it to the terminal devices of all carriages in the form of multicast data; wherein,

[0061] After receiving the initial device connection relationship data packet, the ordinary terminal device does not change the content of the packet, but retransmits it in the form of multicast data.

[0062] S230, after the train head end or train tail end device performs a reverse comparison and confirmation between the received initial connection relationship data packet and the initial connection relationship data packet it has summarized, it obtains a connection relationship comparison success data packet carrying the terminal device number, and sends the connection relationship comparison success data packet to the corresponding peer end respectively.

[0063] In some embodiments, during comparison and verification, the terminal device checks the connection relationship data in the data packet item by item, including carriage number, connection order, and adjacent carriage information, to ensure that the data summarized on both sides is completely consistent. To enhance the accuracy of the comparison, the terminal device also verifies the terminal device number in the data packet. These numbers are unique and used to identify each terminal device on the train. If the comparison result shows that the data on both sides is completely consistent, the device generates a new data packet, namely a "connection relationship comparison successful data packet". This data packet not only contains the verified connection relationship data, but also specifically marks the numbers of all terminal devices involved in the comparison to prove that these devices all played a role in constructing the connection relationship diagram and that the data is consistent.

[0064] For example, if the comparison results are the same, a connection relationship comparison success data packet is sent. After receiving the connection relationship comparison success data packet sent by the other end, the equipment at the head end or tail end of the train compares it with its own equipment number to confirm and obtain the final version of the equipment connection relationship data packet, and sends it to the terminal equipment in all carriages.

[0065] If the comparison results are different, a connection relationship comparison failure data packet is sent, and the calculated device connection relationship is cleared and a new device connection relationship calculation process is started.

[0066] S240, after receiving the connection relationship comparison success data packet sent by the other end, the train head end or train tail end device compares and confirms it with its own device number to obtain the final device connection relationship data packet, and sends it to the terminal devices of all carriages.

[0067] In some embodiments, before comparing and confirming with its own device number, the train head end or train tail end device will check whether the received data packet contains the correct number of the peer device. At the same time, it will also confirm other key information in the data packet, such as timestamps and check codes, to ensure the integrity and timeliness of the data. Once confirmed, the device will consider the received data packet to be valid and reliable.

[0068] For example, after receiving the connection relationship comparison success data packet sent by the other end, the device at the front or rear of the train takes the terminal device with the smaller number as the starting point, stores only the device connection relationship table starting with that number, fills the device connection relationship table into the final version of the device connection relationship data packet, and sends it to the terminal devices in all carriages; wherein,

[0069] After receiving the final version of the device connection relationship data packet, the ordinary terminal device parses out and stores the device connection relationship, and without changing the content of the packet, sends it again in the form of multicast data. Finally, the data packet will be sent to all terminal devices on the train.

[0070] In the embodiments of this disclosure, firstly, the terminal device can determine the carriage type based on the number of associated wireless devices; secondly, it can determine the connection relationship between carriages based on the multicast data sent by adjacent carriages; thirdly, it can obtain a connection relationship comparison success data packet based on the multicast data summarized and mutually confirmed by the devices at the front or rear of the train; finally, the devices at the front or rear of the train compare and confirm the connection relationship comparison success data packet with their own device number to obtain the final device connection relationship data packet, and send it to the terminal devices in all carriages. In this way, it is not necessary to consider the interface compatibility between different manufacturers, and flexible grouping between different train carriages from different manufacturers can be achieved by deploying wireless devices. This solves the problem of wasted transport capacity caused by uneven time distribution, meets the transport capacity requirements at different times, improves transport economy, realizes real-time acquisition of grouping relationships and order, and is simple to operate and easy to maintain.

[0071] The following detailed description, with reference to a specific embodiment, illustrates a wireless-based vehicle reassembly information calculation method 200 provided in this disclosure, as shown below:

[0072] In this embodiment, we will specifically use a train consisting of four carriages as an example for explanation.

[0073] After the terminal device is powered on and initialized, the status of the associated UWB wireless devices is monitored in real time. If the terminal device continuously detects other associated UWB wireless devices and there is only one associated wireless device, the terminal device is determined to be a train head end or train tail end device. The device number of the terminal device is filled into the reporting number data packet, and multicast data carrying the terminal device's own number is sent.

[0074] If the terminal device continuously detects other UWB wireless devices associated with it, and there are two associated wireless devices, then the terminal device is determined to be an ordinary terminal device, and the device number of the terminal device is filled into the reporting number data packet, and multicast data carrying the terminal device's own number is sent.

[0075] After receiving a multicast data packet containing its own number from a terminal device in another carriage, the terminal device parses the device number in the data packet and sorts its own number with the device number in the data packet. If the terminal device is a device at the head or tail of the train, it is sorted according to the device number of the terminal device (if it is 1) first and the device number of the adjacent terminal device (if it is 2) second, with the connection relationship being 1, 2.

[0076] If the terminal device is a regular terminal device, after receiving multicast data carrying its own number sent by the terminal devices in other carriages, the device number of the terminal device (if it is 3) is centered, and the device numbers of two adjacent terminal devices (if they are 2 and 4) are arranged in the order of 2, 3, 4 respectively.

[0077] After obtaining the connection relationship between the carriages, the terminal device fills the connection relationship into the reporting device connection relationship data packet and sends out the reporting device connection relationship data packet carrying the order of the connection relationship between the carriages.

[0078] After receiving a data packet reporting device connection relationships from other devices, a regular terminal device does not change the content of the packet but sends it out again via multicast. Eventually, all the data packets reporting device connection relationships will be aggregated into the device at the head or tail of the train.

[0079] After collecting and summarizing the multicast data carrying the connection order of the carriages sent by the terminal devices of all carriages, the equipment at the front or rear of the train collects and summarizes the multicast data. Then, it parses the device order in the data packets and summarizes the connection relationship of all devices starting from its own number. That is, the equipment at the front or rear of the train obtains two connection relationships that are reversed (front of the train: 1, 2, 3, 4; rear of the train: 4, 3, 2, 1).

[0080] After the train head-end or train tail-end equipment has completed the aggregation of connection relationships, it obtains the connection relationship data between all carriages, fills the connection relationship data into the initial version of the connection relationship data packet, and the train head-end or train tail-end equipment sends the initial version of the connection relationship data packet it has aggregated to all carriages.

[0081] After receiving the initial device connection relationship data packet, the ordinary terminal device does not change the content of the packet, but sends it out again in a multicast manner. Finally, the data packet will be sent to the terminal device at the head or tail of the train.

[0082] After receiving the initial version of the device connection relationship data packet sent by the other end, the device at the head end or tail end of the train compares it in reverse with the initial version of the connection relationship data packet it has summarized. If the comparison results are the same, the device connection relationship comparison success data packet is sent via multicast.

[0083] If the comparison results are different, the device connection relationship comparison failure data packet is sent via multicast, and the calculated device connection relationship is cleared and a new connection relationship calculation process is started.

[0084] After receiving the data packet indicating a successful device connection comparison, the ordinary terminal device does not change the content of the packet but resends it via multicast. Ultimately, the data packet will be sent to the terminal device at the head or tail of the train.

[0085] After the train head or train tail end equipment receives the device connection relationship comparison success data packet sent by the other end, the train head and train tail end terminal equipment compare the device numbers of the two, take the terminal device number with the smaller terminal device number as the starting end, store only the device connection relationship table with the starting end of that number (i.e.: 1, 2, 3, 4), fill the device connection relationship table into the final version of the device connection relationship data packet, and send it to the terminal equipment of all carriages;

[0086] After receiving the final device connection relationship data packet, the ordinary terminal device parses out and stores the device connection relationship, without changing the content of the packet, and then sends it out again in a multicast manner. Finally, the data packet (1, 2, 3, 4) will be sent to all terminal devices on the train.

[0087] After receiving a data packet indicating a failed device connection comparison, a regular terminal device will clear the calculated device connection relationship and start a new connection relationship calculation process. At the same time, without changing the content of the packet, it will resend the packet via multicast. Eventually, the data packet will be sent to all terminal devices on the train.

[0088] After receiving a data packet indicating a failed comparison of device connections from the other end, the terminal equipment at the head and tail of the train will clear the already calculated device connection relationships and start a new connection relationship calculation process.

[0089] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this disclosure is not limited to the described order of actions, because according to this disclosure, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily essential to this disclosure.

[0092] The status monitoring module 310 is used to monitor the status of associated wireless devices in real time after the terminal device is powered on and initialized. If it is continuously detected that the terminal device is associated with other wireless devices, it sends multicast data carrying the terminal device's own number and receives multicast data carrying its own number sent by terminal devices in other carriages to establish and confirm the connection relationship between carriages, and sends multicast data carrying the connection relationship order of the carriages.

[0093] The collection and aggregation module 320 is used for the train head end or train tail end equipment to collect and aggregate multicast data sent by the terminal equipment of all carriages, carrying the order of the connection relationship between the carriages, to obtain the connection relationship data between all carriages, and to fill the connection relationship data into the initial connection relationship data packet. The train head end or train tail end equipment respectively sends the initial connection relationship data packet obtained by itself to the corresponding peer end.

[0094] The reverse comparison module 330 is used to compare and confirm the received initial connection relationship data packet with the initial connection relationship data packet summarized by itself at the head end or tail end of the train, and then obtain a connection relationship comparison success data packet carrying the terminal device number, and send the connection relationship comparison success data packet to the corresponding peer end respectively.

[0095] The confirmation and reporting module 340 is used to compare and confirm the connection relationship comparison success data packet sent by the other end after the train head end or train tail end device receives the connection relationship comparison success data packet sent by the other end with its own device number, obtain the final version of the device connection relationship data packet, and send it to the terminal devices of all carriages.
