[0002] At present, urban rail transit has the characteristics of large differences in passenger flow at different time periods, and urban rail transit mostly uses fixed train formations, and the operation cannot flexibly allocate the number of train vehicles to meet the needs of different transport capacities. Train reconnection / disconnection can flexibly change the number of train formations, taking into account the operational service level and train load rate, solving the problem of capacity waste caused by uneven time distribution, meeting the capacity requirements of different time periods, and improving transportation economy.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0045] In conjunction with the accompanying drawings, a wireless-based vehicle reorganization information calculation method, device and train provided by the embodiments of the present disclosure are described in detail through specific embodiments.

[0046] Figure 1 The structure diagram of a train provided with a wireless vehicle reorganization information calculation device provided by an embodiment of the present disclosure is shown, such as Figure 1 As shown, a train provided with a wireless-based vehicle reorganization information calculation device may include:

[0047] A terminal device and a wireless device are arranged in each train compartment, 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 arranged in each carriage of the train formation, and the terminal device has a unique number on this line; this terminal device uses an Ethernet interface to connect to a wireless device. Considering the length of the carriage, a low-power UWB wireless device is selected, and a directional antenna is used to make the wireless signals in the non-head and tail end carriages cover both ends of the carriage in a direction, and only wireless communication can be carried out with the front and rear carriages. The wireless signals at the front and rear ends of the car only cover the interior of the car in a direction; 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 of a wireless vehicle reorganization information calculation method provided by an embodiment of the present disclosure is shown. Figure 2 As shown, a wireless-based vehicle reconfiguration 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 device in real time. If it is continuously monitored 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 the carriages, and sends multicast data carrying the order of the connection relationship in the carriages.

[0051] In some embodiments, the terminal device can be initialized by setting up an automation system, including: the automation system first receives the regrouping instructions from the control center, and parses the instructions 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 specified terminal device. After the terminal device receives the power-on signal, it starts the internal power management module and performs the power-on operation. During the power-on process, the terminal device will perform a series of self-tests and initialization operations to ensure that the device is in normal working condition.

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

[0053] Exemplarily, after the terminal device is powered on and initialized, the status of the associated wireless device is monitored in real time. If it is continuously monitored that the terminal device is associated with other wireless devices, and the number of the associated wireless devices is one, the terminal device is determined to be a train head end or train tail end device, and the device number of the terminal device is filled into the report number data packet, and multicast data carrying the terminal device's own number is sent;

[0054] If it is continuously monitored that the terminal device is associated with other wireless devices, and the number of associated wireless devices is two, the terminal device is determined to be an ordinary terminal device, and the device number of the terminal device is filled into the report number data packet, and multicast data carrying the terminal device's own number is sent.

[0055] Exemplarily, if the terminal device is a train head end or train tail end device, after receiving multicast data carrying its own number sent by terminal devices in other carriages, the terminal device is sorted in a manner that the device number of the terminal device is first and the device number of the adjacent terminal device is last;

[0056] If the terminal device is a common terminal device, after receiving multicast data with its own number sent by terminal devices in other carriages, the terminal device is sorted in such a way that the device number of the terminal device is in the middle, and the device numbers of the two adjacent terminal devices are in the front and the back 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 connection relationship sequence of the carriages.

[0058] S220, the equipment at the front end or the rear end of the train collects and summarizes the multicast data carrying the connection relationship order of all carriages sent by the terminal equipment 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 equipment at the front end or the rear end of the train respectively sends the initial version of the connection relationship data packet summarized by itself to the corresponding opposite end.

[0059] In some embodiments, during the transmission process, the device will use a reliable communication protocol, such as TCP / IP or a train-specific communication protocol, to ensure that the data can be accurately transmitted to the other end. At the same time, in order to verify whether the data is successfully sent and received, the device will also wait for a confirmation signal from the other end; once the confirmation signal is received, the equipment at the head and tail ends of the train can confirm that the connection relationship data of the entire train has been successfully synchronized to both ends, providing a solid foundation for subsequent information transmission and control system operation.

[0060] Exemplarily, the train head end or train tail end device summarizes the connection relationship based on the reporting device connection relationship data packet, obtains the connection relationship data between all carriages, fills the connection relationship data into the initial version of the 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 version of the device connection relationship data packet, the ordinary terminal device does not change the content of the packet, and sends it out again in the form of multicast data.

[0062] S230, after the train head end or train tail end device reversely compares and confirms the received initial version connection relationship data packet with the initial version connection relationship data packet summarized by itself, 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 opposite end respectively.

[0063] In some embodiments, when performing comparison confirmation, the terminal device will check the connection relationship data in the data packet item by item, including the car number, connection order, adjacent car information, etc., to ensure that the data summarized on both sides are completely consistent. In order to enhance the accuracy of the comparison, the terminal device will also verify the terminal device numbers in the data packet, which are unique and are used to identify each terminal device on the train. If the comparison results show that the data on both sides are exactly the same, the device will generate a new data packet, namely the "connection relationship comparison successful data packet". This data packet not only contains the verified connection relationship data, but also specially marks the numbers of all terminal devices involved in the comparison to prove that these devices have played a role in constructing the connection relationship diagram and the data is consistent.

[0064] Exemplarily, if the comparison results are the same, a connection relationship comparison success data packet is sent, and after the train head end or train tail end device receives the connection relationship comparison success data packet sent by the other end, it compares and confirms with its own device number, obtains the final version device connection relationship data packet, and sends it to the terminal devices of 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, obtains the final version device connection relationship data packet, and sends it to the terminal devices in all carriages.

[0067] In some embodiments, before comparing and confirming with its own device number, the device at the head end or the tail end of the train will check whether the received data packet contains the correct number of the other device. At the same time, it will also confirm other key information in the data packet, such as timestamp, checksum, etc., 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] Exemplarily, after receiving the connection relationship comparison success data packet sent by the other end, the equipment at the head end or the tail end of the train takes the terminal equipment with a smaller number as the starting end, only stores the equipment connection relationship table with the number as the starting end, and fills the equipment connection relationship table into the final version equipment connection relationship data packet, and sends it to the terminal equipment in all carriages; wherein,

[0069] After receiving the final version device connection relationship data packet, the ordinary terminal device parses and stores the device connection relationship, and does not change the content of the packet, and 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 the present disclosure, firstly, the terminal device can determine the type of carriage according to the number of associated wireless devices; secondly, the connection relationship between the carriages can be determined according to the multicast data sent by the adjacent carriages; thirdly, the connection relationship comparison success data packet can be obtained according to the multicast data summarized and mutually confirmed by the train head end or train tail end device; finally, the train head end or train tail end device compares and confirms the connection relationship comparison success data packet with its own device number, 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, and different train carriages of different manufacturers can be flexibly grouped by arranging wireless devices, which solves the problem of capacity waste caused by uneven time distribution, meets the capacity requirements of different time periods, improves transportation economy, and realizes real-time acquisition of grouping relationship and sequence, which is simple to operate and convenient to maintain.

[0071] In conjunction with a specific embodiment, a wireless-based vehicle reorganization information calculation method 200 provided by the present disclosure is described in detail below, as shown below:

[0072] In this embodiment, a train including four carriages is specifically taken as an example for description.

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

[0074] If the terminal device continuously monitors that it is associated with other UWB wireless devices, and the number of associated wireless devices is two, the terminal device is determined to be a common terminal device, and the device number of the terminal device is filled into the report number data packet, and multicast data carrying the terminal device's own number is sent;

[0075] After receiving a multicast data packet carrying 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 train head or train tail device, the device number of the terminal device (if 1) is in front and the device number of the adjacent terminal device (if 2) is in the back, and the connection relationship is 1, 2.

[0076] If the terminal device is a common terminal device, after receiving the multicast data with its own number sent by the terminal devices in other carriages, the device number of the terminal device (if 3) is placed in the middle, and the device numbers of the two adjacent terminal devices (if 2 and 4) are arranged in the front and back respectively, and the connection relationship is 2, 3, 4;

[0077] After the terminal device obtains the connection relationship between the carriages, the terminal device fills the connection relationship into the reporting device connection relationship data packet, and sends the reporting device connection relationship data packet carrying the connection relationship sequence of the carriages;

[0078] After receiving the data packets of reporting device connection relationship sent by other devices, ordinary terminal devices will send them out again in multicast mode without changing the contents of the packets. Finally, all the data packets of reporting device connection relationship will be aggregated to the equipment at the head end or the tail end of the train.

[0079] After the equipment at the head end or the tail end of the train collects and summarizes the multicast data sent by the terminal equipment of all carriages and carrying the connection relationship sequence of the carriages, it parses the device sequence in the data packet and summarizes the connection relationship of all devices with its own number as the starting number, that is, the equipment at the head end or the tail end of the train obtains two reversed connection relationships (head end of the train: 1, 2, 3, 4; tail end of the train: 4, 3, 2, 1);

[0080] After the equipment at the head end or the tail end of the train completes the connection relationship summary, the connection relationship data between all carriages are obtained, and the connection relationship data are filled into the initial connection relationship data packet. The equipment at the head end or the tail end of the train respectively sends the initial connection relationship data packet obtained by summarizing itself to all carriages;

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

[0082] After receiving the initial version of the device connection relationship data packet sent by the other end, the equipment at the head end or the tail end of the train will reversely compare it with the initial version of the connection relationship data packet summarized by itself. If the comparison results are the same, the equipment connection relationship comparison success data packet will be sent in multicast mode;

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

[0084] After receiving the data packet of successful device connection relationship comparison, the ordinary terminal device does not change the content of the packet and sends it out again in multicast mode. Finally, the data packet will be sent to the terminal device at the head end or the tail end of the train.

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

[0086] After receiving the final version of the device connection relationship data packet, the ordinary terminal device parses out the device connection relationship and stores it, and does not change the content of the packet, and sends it out again in a multicast manner. Finally, the data packet (1, 2, 3, 4) will be sent to all the terminal devices on the train;

[0087] After receiving the data packet indicating the device connection relationship comparison fails, the ordinary terminal device clears the calculated device connection relationship and starts a new connection relationship calculation process. At the same time, the packet content is not changed and it is sent out again in a multicast mode. Finally, the data packet is sent to all the terminal devices on the train.

[0088] After the terminal devices at the head and tail ends of the train receive the device connection relationship comparison failure data packet sent by the other end, the calculated device connection relationship is cleared and a new connection relationship calculation process is started.

[0089] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present disclosure.
