[0039] In order to enable those skilled in the art to better understand the solutions of the present disclosure, and to fully understand and implement the process of how the present disclosure applies technical means to solve technical problems and achieve corresponding technical effects, the technical solutions 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 only part of the embodiments of the present disclosure, not all of the embodiments. The embodiments of the present disclosure and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the scope of protection of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present disclosure.
[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0041] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0042] Since the traction load capacity of a train pulled by a single locomotive is limited, it is difficult to meet the demand for higher transportation capacity. When a larger transport volume is required, it is necessary to use multiple locomotives to connect the train to increase the transportation capacity of the entire train.
[0043] During train reconnection, the locomotive operated by a driver is called the master locomotive, while the locomotive without a driver, which receives control commands via the train backbone network device or system, is called the slave locomotive. The exchange of control commands and other data between the master and slave locomotives via wireless communication is called wireless reconnection. In wireless reconnection, the process of discovering the actual train configuration (topology) is called train initialization.
[0044] During the initial train operation, the master control car needs to obtain the current order of the slave control cars and determine the orientation of each car in order to configure the reconnection communication network and complete wireless reconnection. Traditionally, these parameters were configured manually. Freight trains are typically very long, and manual configuration required walking from the front to the rear of the train, which was time-consuming and inefficient. Some technical solutions have achieved automatic configuration, but these solutions have many limitations, are complex, require a large amount of computation, are time-consuming, and can easily cause misconnections with adjacent trains.
[0045] Some technical solutions for wireless train reconnection have been proposed in this field. However, these technical solutions have the following technical problems when applied:
[0046] 1) The manual configuration technical solution cannot automatically start the initial operation and requires manual configuration of train formation information, which is time-consuming and inefficient, or the automatic initial operation effect is not good.
[0047] 2) Wireless ranging-based train initial operation solutions rely heavily on ranging accuracy and require a large number of pre-defined reference nodes. Calculations require a master node, which is computationally intensive and places a high load on the master node. Therefore, they are only suitable for determining the relative position of trains within the wireless signal coverage area of the two trains. Furthermore, if there are trains on adjacent tracks, wireless ranging-based automatic train initial operation solutions are prone to misconnections, reducing the success rate of initial operation.
[0048] 3) Satellite-based positioning for initial train operations requires a long positioning time, typically exceeding 30 seconds. Furthermore, positioning requires a clear area around the train, and its positioning performance struggles to meet the initial train operation requirements for identifying adjacent vehicles. This can easily lead to misconnections with adjacent trains, reducing the initial run success rate.
[0049] 4) The technical solution of the wireless backbone network based on directional antennas, due to the existence of antenna side lobes, the wireless signals transmitted by adjacent rail vehicles are easily received by the rail vehicle, and thus identified as the rail vehicle itself, which is easy to connect with the adjacent rail train and cause misconnection, reducing the initial operation success rate.
[0050] 5) The method of identifying adjacent vehicles based on wireless signal quality is prone to identification errors or reduced identification speed due to interference from wireless signals on adjacent tracks. It is also prone to misconnection with trains on adjacent tracks, thus reducing the initial operation success rate.
[0051] In response to the defects of the above technical solutions, the present disclosure proposes a technical solution for automatic initial operation based on a two-layer architecture, which realizes the automatic initial operation of the wireless train backbone network.
[0052] The disclosed technical solution does not rely on external signals such as satellite positioning signals, ground positioning reference coordinate points, or the accuracy of inter-train ranging. It has a high initial run success rate and supports automatic initial run of two or more trains, offering high flexibility and effectively resolving the technical issue of low automatic initial run success rate during wireless reconnection.
[0053] In this disclosure, multiple locomotives are organized into a group for coordinated operation. The first locomotive in the forward direction is called the master locomotive. Locomotive driving operations are performed from the front cab of the master locomotive. Each locomotive is equipped with a train backbone network device, and the hardware structure of the train backbone network devices in each locomotive is not significantly different. The difference is that the train backbone network device in the front cab of the master locomotive directly performs human-machine interaction, so it is called the main train backbone network device. All other train backbone network devices are called secondary train backbone network devices.
[0054] The present disclosure can achieve the following beneficial effects:
[0055] 1) Automatic discovery of train topology
[0056] The present disclosure utilizes a two-layer architecture to achieve the decoupling of train topology discovery (access control) and wireless communication. No human intervention is required during the initial operation of the train, and the direction and vehicle information of adjacent vehicles can be automatically obtained, thereby achieving automatic discovery of the train topology.
[0057] 2) Support automatic initial operation of multiple nodes
[0058] The wireless backbone network device disclosed in the present invention can adapt to the initial operation of the train wireless backbone network in the case of two or more train sections.
[0059] 3) Stable automatic initial operation of trains
[0060] In other technical solutions, wireless signals propagate circumferentially in space, resulting in poor directionality and being easily received by wireless devices on adjacent tracks. Consequently, the wireless backbone network can easily mistakenly connect to the wireless backbone network devices of vehicles on other tracks, leading to initial operation failure of the wireless backbone network. However, in the present disclosure, due to the two-layer architecture, the connection topology of the wireless communication layer is controlled by the access control layer. This effectively identifies the vehicle on the track and avoids initial operation failure of the wireless backbone network.
[0061] 4) Adapt to various wireless communication technologies
[0062] The wireless communication layer in this device does not rely on a specific wireless communication method and can adapt to a variety of different wireless communication methods.
[0063] 5) Lower requirements for the computing performance of the initial hardware system
[0064] Since the present disclosure performs grouping one by one instead of directly obtaining all locomotive information, the requirements for hardware computing performance are relatively low.
[0065] Example 1
[0066] Figure 1 FIG. 1 is a schematic diagram of a reconnection method according to an embodiment of the present disclosure. Figure 1 As shown, a reconnection method includes:
[0067] Step S100 , when a handshake signal is detected within a preset angle and / or a preset distance, a train network index is generated;
[0068] Step S200: Reconnecting different vehicles according to the train network index.
[0069] Figure 2 is a hierarchical schematic diagram of the reconnection method of the embodiment of the present disclosure, such as Figure 2 As shown, the method of this embodiment is implemented in two layers: an access control layer and a wireless communication layer. In the access control layer, when a handshake signal is detected within a preset angle and / or distance, a train network index is generated through a first access control and a second access control. In the wireless communication layer, the first wireless node and the second wireless node reconnect different trains based on the train network index.
[0070] In this embodiment, when a handshake signal is detected within a preset angle and / or a preset distance, a train network index is generated; reconnection between different sections of vehicles is performed based on the train network index, thereby dividing the reconnection process into two layers: an access control layer and a wireless communication layer; in the access control layer, a train network index is generated only when a handshake signal is detected within a preset angle and / or a preset distance, so that the train can only reconnect with vehicles on the same track within a preset angle and / or a preset distance, overcoming the technical problem that the train is easily connected to a train on an adjacent track during reconnection, causing misconnection.
[0071] Example 2
[0072] Based on the above embodiment, when a handshake signal is detected within a preset angle and / or a preset distance, a train network index is generated, including:
[0073] When a handshake signal is detected within a preset angle and / or a preset distance, the vehicle in this section and the vehicle at the other end enter a handshake state;
[0074] After the handshake is completed, the vehicle in this section exchanges access control information with the vehicle at the other end;
[0075] Generate a train network index based on the access control information.
[0076] The train network index is generated based on the access control information, including:
[0077] The train topology is obtained by sequencing vehicles in different sections based on access control information;
[0078] Generate a train network index based on the train topology.
[0079] In this embodiment, at the access control layer, the primary train backbone network device exchanges access control information (such as the train node number, vehicle terminal number, vehicle network address, and other information) with the secondary train backbone network device by identifying the handshake signal from the secondary train backbone network device. Based on the access control information, the primary train backbone network device sorts the train formation, vehicle direction, and other information to achieve train topology discovery and obtain the train topology, and generates a train network index based on the train topology. When the train backbone network device of the first car is the primary train backbone network device, the train backbone network device of the second car is the secondary train backbone network device. When the train backbone network device of the second car is the primary train backbone network device, the train backbone network device of the first car is the secondary train backbone network device.
[0080] In this embodiment, the access control layer of the master train backbone network device exchanges a train network index with the wireless communication layer. The wireless communication layer configures the wireless access relationship and wireless communication parameters between the master and slave trains based on the train network index, enabling automatic networking of the train wireless backbone network and thus achieving initial operation of the train wireless backbone network. The train network index contains all data and descriptions related to the actual train backbone network topology.
[0081] Example 3
[0082] Based on the above embodiment, before the handshake signal is detected within the preset angle and / or preset distance, the method further includes:
[0083] The distance between this section's vehicle and the opposite vehicle gradually decreases and a handshake signal is issued.
[0084] Among them, the distance between the vehicles in this section and the vehicles at the opposite end gradually decreases, including at least one of the vehicles in this section and the vehicles at the opposite end approaching each other, the vehicles in this section approaching the vehicles at the opposite end, or the vehicles at the opposite end approaching the vehicles in this section.
[0085] The access control information includes:
[0086] At least one of the vehicle number, the connected vehicle terminal number, and the vehicle network address.
[0087] Figure 3This is a schematic diagram of a train-based reconnection method according to an embodiment of the present disclosure. In this embodiment, the system is powered on and the device initialization begins. After the initialization self-test passes, each train backbone network device starts sending handshake signals of the vehicle in the access control layer. Figure 3 As shown in the figure, when the master vehicle is the vehicle in the current section, the slave vehicle is the opposite vehicle. When the slave vehicle is the vehicle in the current section, the master vehicle is the opposite vehicle. At this point, the current and opposite vehicles begin to approach each other. When the distance between the current and opposite vehicles falls below a distance threshold, the train backbone network devices of the current and opposite vehicles at the access control layer receive a handshake signal transmitted by the opposite vehicle and the current vehicle at the access control layer, and the current and opposite vehicles enter a handshake state.
[0088] In this embodiment, after the handshake at the access control layer is successful, the vehicles in this section exchange access control information with the vehicles at the opposite end, including vehicle numbers, such as the first vehicle and the second vehicle, and vehicle terminal numbers, such as the first terminal and the second terminal. Based on the vehicle information, the access control layer of the master vehicle calculates the grouping and direction information of the vehicles in this section and the vehicles at the opposite end. Figure 3 In the embodiment, the first car is on the left side of the second car, and the second end of the first car is connected to the first end of the second car. Wherein, marshaling is a single car or a group of cars that will not be separated during normal operation.
[0089] In this embodiment, the wireless communication layer controls the access relationship between the vehicle in this section and the vehicle at the other end. Figure 3 The wireless communication layer at the second end of the first vehicle communicates wirelessly with the wireless communication layer at the first end of the second vehicle. The first and second wireless backbone network devices within each vehicle can exchange data via wired or fixed wireless access. This completes the initial operation of the wireless backbone network in a two-vehicle scenario.
[0090] In this embodiment, the marshaling process is performed sequentially. The above example involves marshaling two cars. For a three-car marshaling process, the process involves first completing the marshaling of the two cars and then adding the additional car. The process for adding additional cars to the marshaling is as follows: After the initial operation of the wireless backbone network between the current car section and the opposite car is complete, the marshaling is formed. The current car section sends a handshake signal to both sides at the wireless access control layer, waiting for the other opposite car to approach and join the current marshaling. When another car approaches, whether from the left side of the first car or the right side of the second car, the above handshake and marshaling process is repeated, the train index is updated, and the additional car section is connected to the current marshaling wireless backbone network.
[0091] Example 4
[0092] Figure 4 FIG. 1 is a schematic diagram of a train backbone network device according to an embodiment of the present disclosure. Figure 4 As shown, based on the above embodiment, a train backbone network device includes:
[0093] The access control module 10 is configured to generate a train network index when a handshake signal is detected within a preset angle and / or a preset distance;
[0094] The wireless communication module 20 is used to reconnect different vehicles according to the train network index.
[0095] In the present disclosure, the train backbone network device includes an access control module 10 and a wireless communication module 20, which are respectively used to implement the methods of the access control layer and the wireless communication layer and achieve the technical effects of the above-mentioned embodiments, wherein the access control module 10 serves as the access control layer of the train backbone network device, and the wireless communication module 20 serves as the wireless communication layer of the train backbone network device.
[0096] The access control module and wireless communication module in each train backbone network device can communicate with each other, and the wireless communication modules of different train backbone network devices can communicate with each other. When within a preset angle and / or preset distance, the access control modules of different train backbone network devices can communicate with each other.
[0097] Those skilled in the art will understand that, since there is generally no difference in the hardware structure of the train backbone network devices of each locomotive, the technical solution formed by swapping the positions of the main train backbone network device and the secondary train backbone network device described above is also within the scope of this disclosure.
[0098] Example 5
[0099] Based on the above embodiment, the access control module 10 includes:
[0100] One of the following modules: RFID reading module, optical transceiver module or image acquisition module.
[0101] Among them, the access control module includes an RFID reading module, each vehicle is equipped with an RFID tag, and the handshake signal is a signal fed back by the RFID tag in response to the card reading signal sent by the RFID reading module.
[0102] The access control module includes an optical transceiver module, and the handshake signal is a signal sent by the optical transceiver module of the opposite vehicle.
[0103] Among them, the access control module includes an image acquisition module, each vehicle is equipped with its own optical beacon, and the handshake signal is the signal fed back by the image acquisition module when it recognizes the optical beacon.
[0104] In actual applications, the access control module also includes a processor for generating a train network index based on the signal received by the RFID reading module, the optical transceiver module or the image acquisition module, so as to reconnect different sections of the vehicle through the wireless communication module.
[0105] In this embodiment, the access control module 10 is implemented using RFID or optical communication technology, so that the access control module of the primary train backbone network device can only receive and identify the signal of the access control module of the secondary train backbone network device when it is within a preset distance and / or preset angle. In this embodiment, an optical transceiver module can be arranged in the vehicle of this section to receive the signal transmitted by the optical transceiver module of the opposite vehicle, obtain information such as the number and direction of the opposite vehicle, and obtain the information from the optical transceiver module.
[0106] In this embodiment, cameras are deployed on the vehicles in this section, and optical beacons (such as QR codes, photoelectric matrices, etc.) that can reflect the vehicle number and direction of the vehicle are deployed on the opposite vehicle. The cameras identify the optical beacons of the opposite vehicle, thereby obtaining the relative positional relationship between the opposite vehicle and the vehicles in this section, and then calculating the train network index. The connection relationship between the wireless communication modules is controlled based on the train network index. In this embodiment, cameras can also be deployed on the vehicles in this section, and artificial intelligence can be used to identify information such as the number and direction of the opposite vehicle, thereby obtaining the relative positional relationship between the opposite vehicle and the vehicles in this section, and then calculating the train network index. The connection relationship between the wireless communication modules is controlled based on the train network index.
