Description

Technical Field

[0001] The present application relates to the field of rail transit, and in particular to a method, device and medium for identifying a rail transit vehicle reconnection mode. Background Art

[0002] The reconnection technology that complies with the Train Communication Network (TCN) standard is widely used in the field of rail transit. Two or more vehicles reconnected through the Wire Train Bus (WTB) can share information with each other and achieve synchronous control. For vehicles equipped with two driver consoles (I end and II end), there are three reconnection methods when reconnecting, including: reconnecting I end with II end, reconnecting I end with I end, and reconnecting II end with II end. After the reconnection is completed, the driver needs to see the reconnection status of the vehicle on the human-computer interaction interface of the master control vehicle.

[0003] At present, the common technical means is to set a reconnection button in the driver's cab or set the head and tail relays at the ends of the vehicle. After the vehicle is reconnected, the relay at the reconnected end is high level and the non-reconnected end is low level, so as to judge the reconnection status and the reconnection method of the vehicle. This method is only applicable to the reconnection of two vehicles. If three or more vehicles are reconnected, the middle vehicle has the reconnection relays at both ends powered. Therefore, it can only be determined that the vehicle reconnection status is good, but the vehicle reconnection method cannot be determined, which makes it difficult for the driver to judge the vehicle status and fault location.

[0004] It can be seen that how to identify the reconnection mode of multiple vehicles is a technical problem that people in this field continue to solve. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The core of this application is to provide a method, device and medium for identifying the reconnection mode of rail transit vehicles, which are used to identify the reconnection mode of multiple vehicles.

[0044] At present, in the process of identifying the vehicle reconnection mode, it is determined according to the power-on status of the head and tail relays set at the ends of the vehicle. However, since the head and tail relays of the middle vehicle are both powered, it is impossible to judge the reconnection mode of more than three vehicles using the existing method. Therefore, in this application, the location information of the nodes in the WTB network and the characteristics of the WTB network are fully utilized to complete the identification and judgment of the vehicle reconnection mode and the reconnection end without the need for hard wires or other external indication signals.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 A flow chart of a method for identifying a rail transit vehicle reconnection mode provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0046] S10: Obtain the number of reconnected vehicles and the current node of the current vehicle on the reconnected network;

[0047] S11: Obtain the index of each node of each reconnected vehicle, and the direction of the current node and the node in the reconnected vehicle on the reconnected network; wherein each node corresponds to a unique index;

[0048] S12: Determine the reconnection end of each reconnected vehicle according to the index and direction of the node to determine the reconnection mode of each reconnected vehicle.

[0049] In the process of identifying the reconnection mode of rail transit vehicles, the rail transit vehicle reconnection method and system used include a network control system (Train Control and Management System, TCMS), a central control unit, and a human-computer interaction device. TCMS includes a multifunction vehicle bus (Multifunction Vehicle Bus, MVB), a WTB, and a train network main and standby control module. The MVB is used for communication connection between the main and standby control modules. The central control unit is responsible for receiving data on the train network, running the logic control software, outputting control instructions, and is configured with WTB network connectors X1, X2, X3, and X4. X1 and X2 are a pair as channel A, and X3 and X4 are a pair as channel B. The WTB network connection mode of a train is that X1 and X3 of the central control unit are respectively connected to X2 and X4 of another central control unit, and the unconnected connectors are used for reconnection with other trains. The human-computer interaction device is used to receive train network data and provide display information. Figure 2A schematic diagram of a vehicle reconnection provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, each vehicle contains two central control units, end I and end II. The internal connection of each vehicle is WTB (solid arrow), and the connection between vehicles is WTB network (dotted arrow).

[0050] When obtaining the number of reconnected vehicles, since two central control units are set in each vehicle, after the vehicles are reconnected, the total number of nodes is obtained through the WTB network. The total number of nodes divided by 2 represents the number of reconnected trains.

[0051] When obtaining the current node of the current vehicle on the reconnection network, obtain the address information of each node in the current vehicle; wherein each node corresponds to unique address information; determine the current node of the current vehicle on the reconnection network according to the address information. Set the device address of the central control module at the I end of each train to A1, and the device address of the central control module at the II end to A2, and A1 is not equal to A2. The control software in the central control module reads the respective device addresses respectively to determine whether the node on the reconnection network is located at the I end of the driver's cab or the II end of the driver's cab.

[0052] For two nodes on the same train, their reconnection mode is fixed and in the same direction; the WTB network will initialize the nodes on the network, i.e. the central control unit, and assign node identifiers. The initialization includes determining the master node of the WTB network, generating the direction of the master node and the remaining nodes on the reconnection network, and assigning node index numbers. The reconnection end of each reconnected vehicle is determined according to the node index and direction to determine the reconnection mode of each reconnected vehicle.

[0053] The method for identifying the reconnection mode of rail transit vehicles provided in this embodiment includes: obtaining the number of reconnected vehicles and the current node of the current vehicle on the reconnection network; obtaining the node index of each reconnected vehicle and the direction of the current node and the nodes in the reconnected vehicle on the reconnection network; wherein each node corresponds to a unique index; according to the node index and direction, the reconnection end of each reconnected vehicle is determined to determine the reconnection mode of each reconnected vehicle. It can be seen that this method realizes the identification of the vehicle reconnection mode according to the direction of the current node and each node in the reconnected vehicle on the reconnection network and the node index of each reconnected vehicle.

[0054] When determining the reconnection mode of the reconnected vehicles according to the index of the node, the direction of the current node and the nodes in the reconnected vehicles on the reconnection network, a preferred implementation is that each reconnected vehicle includes two nodes; determining the reconnection end of each reconnected vehicle according to the index and direction of the node to determine the reconnection mode of each reconnected vehicle includes:

[0055] In the case where the current node and the nodes in the reconnected vehicle are in the same direction on the reconnected network, determine whether the index of the current node is the smallest index or the largest index among the indexes of all the nodes of the reconnected vehicle; if so, determine the reconnected end to be a node in the current vehicle other than the current node, as a first reconnection mode; if not, determine the reconnected end to be the current node of the current vehicle, as a second reconnection mode;

[0056] When the directions of the current node and the nodes in the reconnected vehicle on the reconnected network are inconsistent, the reconnected end is determined according to the index of the current node as a third reconnection mode.

[0057] Determine the direction of the current node and the direction of the remaining nodes. If the directions are consistent, the vehicle reconnection methods are consistent, otherwise the vehicle reconnection methods are inconsistent. After determining the reconnection method, it is necessary to determine the reconnection end. The node with index number 0 or the largest must be at both ends. Therefore, if the node with device address A1 has an index of 0 or the largest index number (total number of nodes - 1), the reconnection end is the device with device address A2 in the same vehicle, and the same applies to the node with device address A2. After determining the reconnection end of the end vehicle, combined with the determined reconnection method, the reconnection method of all vehicles can be obtained.

[0058] In the method provided in this embodiment, the reconnection mode of the reconnected vehicle is determined according to the index of the node and the direction of the current node and the nodes in the reconnected vehicle on the reconnected network. On the basis of determining the direction on the reconnected network, the reconnection mode of the vehicle can be determined more accurately according to the unique node index.

[0059] In order to facilitate determining the reconnection mode according to the index of the node, a preferred implementation is that determining the index of each node of each reconnected vehicle includes:

[0060] Get the connection order of the reconnected vehicles;

[0061] The nodes of the reconnected vehicle are numbered according to the connection sequence to determine the index of each node.

[0062] by Figure 2 Taking the first three trains in the example, the first train, the second train, and the third train are connected in sequence; the node indexes of the I end of the first train, the II end of the first train, the I end of the second train, the II end of the second train, the I end of the third train, and the II end of the third train can be marked as 0, 1...7 in sequence.

[0063] The present embodiment provides for numbering each node in sequence according to the connection sequence of the vehicles. The nodes are numbered regularly, so that the reconnection end can be determined according to the node number and the fault position can be located quickly and accurately in the event of a fault.

[0064] After determining the number of reconnected vehicles and the direction of the current node and the nodes in the reconnected vehicles on the reconnected network, in order to facilitate other reconnected vehicles to synchronously obtain information and improve data transmission efficiency, a preferred implementation is that after obtaining the number of reconnected vehicles and the direction of the current node and the nodes in the reconnected vehicles on the reconnected network, the method for identifying the reconnection mode of rail transit vehicles also includes:

[0065] The direction and number of coupled vehicles are shared among the coupled vehicles through the WTB network.

[0066] The WTB bus is mainly used for train-level communication, with a transmission rate of 1Mbps. It can realize the transmission of process data and message data. Its biggest feature is that it has the function of initial train operation (the function of initial train operation means that when the configuration of the train vehicle changes, it can automatically address the vehicle and form a new train topology without human intervention).

[0067] The method provided in this embodiment for sharing the direction and the number of connected vehicles among connected vehicles through the WTB network enables information synchronization between different connected vehicles and improves the efficiency of information synchronization.

[0068] In implementation, in the process of determining the reconnection mode, it may take a long time to determine the reconnection mode. In order to obtain the reconnection mode, the preferred implementation is:

[0069] From the beginning of determining the reconnection end of each reconnected vehicle according to the index and direction of the node to determine the reconnection mode of each reconnected vehicle, judging whether the reconnection mode of each reconnected vehicle is determined within a preset time;

[0070] If not, return to the step of obtaining the number of reconnected vehicles and the current node of the current vehicle on the reconnected network.

[0071] The preset time can be determined according to the number of reconnected vehicles, etc. The more reconnected vehicles there are, the longer the preset time can be set. If the reconnection method is not determined within the preset time from the beginning of determining the reconnection method, the process continues to return to the step of obtaining the number of reconnected vehicles and the current node of the current vehicle on the reconnection network, that is, the reconnection method is determined again within the preset time. By setting the preset time, the user is prevented from waiting for a long time to obtain the reconnection method, and the reconnection method can be obtained as much as possible.

[0072] After obtaining the reconnection mode, in order to facilitate the user to intuitively understand the reconnection mode, a preferred implementation is that after determining the reconnection mode of each reconnected vehicle, the method for identifying the reconnection mode of a rail transit vehicle further includes:

[0073] The reconnection mode is displayed in the driver's cab of each vehicle.

[0074] A human-machine interaction device is installed in the driver's cab. There is no limitation on the human-machine interaction device, such as a display screen. There is no limitation on the way of displaying the reconnection on the human-machine interaction device, as long as the reconnection way can be displayed, so that the user can intuitively understand the reconnection way of the vehicle.

[0075] In the above embodiments, the identification method of the rail transit vehicle reconnection mode is described in detail, and the present application also provides an embodiment corresponding to the identification device of the rail transit vehicle reconnection mode. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the functional module perspective, and the other is based on the hardware perspective.

[0093] In order to make the technical personnel in this field better understand the present application scheme, the following is combined with the attached Figure 5 The present application is further described in detail with specific implementation methods. Figure 5 A flowchart of a method for identifying a two-train reconnection mode with the I end as a controller provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the method includes:

[0094] S13: Obtain address coding information;

[0095] S14: Determine whether the address code is A1; if so, proceed to step S15;

[0096] S15: I-terminal controller;

[0097] S16: Obtain the direction signal of the reconnection node and the total number of nodes;

[0098] S17: Determine whether the direction of this node is the same as that of the other nodes; if so, proceed to step S18; if not, proceed to step S23;

[0099] S18: Determine whether the node index is 0 or the maximum (total nodes - 1); if so, proceed to step S19; if not, proceed to step S21;

[0100] S19: A2 is the reconnection end;

[0101] S20: reconnection mode 1; proceed to step S28;

[0102] S21: A1 is the reconnection end;

[0103] S22: reconnection mode 2; proceed to step S28;

[0104] S23: The directions are inconsistent; proceed to step S24 or proceed to step S26;

[0105] S24: A2 is the reconnection end;

[0106] S25: reconnection mode 3; proceed to step S28;
