Figure 1 With the rapid development of train technology, the continuous improvement of train service quality level and passenger demand, the requirement of high-speed EMU passenger car information service is also higher and higher, due to some deficiencies existing in the train communication network, which makes it necessary to introduce other types of communication network in the train communication network, forming a situation of coexistence of multiple networks, in order to realize high communication rate, reliability and anti-interference, and conveniently provide high-quality information entertainment service for passengers.

[0028] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict.

[0029] In the process of implementing the present application, the inventors found that there are differences between passenger train sets and freight train sets in PIS systems, lighting systems, and freight information systems. When the passenger train sets and the freight train sets are reconnected using the same train-level communication mode, the embodiments of the present application configure both of them with the same train-level data transmission specification, so that the passenger train sets and the freight train sets are reconnected and interconnect with each other. Because the on-board electrical systems of the two types of trains are quite different, the faults reported to the human-machine interface will have great differences. In order to ensure that the analysis and processing of the passenger train sets and the freight train sets are realized with less changes in the existing train hardware, the embodiments of the present application establish a reconnection data processing model between trains to process the different data of the two types of trains and realize the interconnection and intercommunication of data.

[0030] Embodiments

[0031] As shown in Figure 2 , a method suitable for interconnection and intercommunication of reconnected trains, the first train and the second train of the reconnection use the same train-level communication mode, comprising:

[0032] S10, configuring the first train and the second train of the reconnection with the same train-level data transmission specification;

[0033] S20, based on the train-level communication interface of the first train and the second train, establishing a reconnection data processing model for differentially processing the reconnection data between trains, and realizing the interconnection and intercommunication between the signals of the first train and the second train.

[0034] Specifically, in the S10, the train-level communication mode is WTB. In this embodiment, the first train of the reconnection is a passenger train set, and the second train of the reconnection is a freight train set. The following will be directly replaced by the passenger train set and the freight train set.

[0035] In this embodiment, considering the differences between the two types of trains (passenger train sets and freight train sets) in PIS systems, lighting systems, freight information systems, and switch equipment, the passenger train set uses the WTB+MVB bus communication mode, so that the vehicle-level of the freight train set and the passenger train set is MVB-controlled, and the train-level communication is performed through WTB. After the two types of trains are reconnected, the reconnection network topology diagram is as shown in Figure 3 .

[0036] In this embodiment, the passenger train set and the freight train set are reconnected through a full-automatic coupler. When the two types of trains are reconnected, the full-automatic coupler realizes the signal interconnection of the safety loop line between vehicles, the train-level control hard line, the network train-level bus, the passenger information system (including communication, signal, and control lines), and the standby line; realizes the automatic connection of the mechanical, air circuit, and circuit, and the automatic pneumatic uncoupling can be realized in the driver's room operation.

[0037] As Figure 4 and Figure 5 shown, in particular, the reconnection data processing model includes:

[0038] S201, the train level communication port of the passenger train and the freight train is divided into P1, P2, P3, P4 and P5; wherein: as Figure 6 , Figure 7 shown:

[0039] P1 port data is sent by the master control car;

[0040] P2 port data is sent by the slave control car to the master control car, which is used for the master control car to perform train level control;

[0041] P3 port data is sent by all units, mainly for vehicle key equipment status;

[0042] P4 port data is sent by all units, mainly for vehicle equipment status;

[0043] P5 port data is sent by all units, mainly for vehicle fault information;

[0044] S202, a data conflict processing strategy based on P1, P2, P3, P4 port data and a fault control strategy based on P5 port data are established;

[0045] S203, when the passenger train and the freight train are reconnected: the reconnection data of the passenger train and the freight train is analyzed for differences, the master control car type and the slave control car type are determined, and the master control car type and the slave control car type execute corresponding control logic according to the data conflict processing strategy and the fault control strategy;

[0046] Wherein, the control logic is the running control logic stored in the running management system of the passenger train or the freight train.

[0047] In this embodiment, the S203 includes:

[0048] S2031, setting the frame meaning of each data frame of the reconnection signal in the train level communication;

[0049] S2032, according to the frame meaning of each data frame, the master control car type and the slave control car type are parsed, as well as the reconnection end and the non-reconnection end of the master control car type, and the reconnection end and the non-reconnection end of the slave control car type;

[0050] S2033, based on the data conflict processing strategy and the fault control strategy, the reconnection end and the non-reconnection end of the master control car type, and the reconnection end and the non-reconnection end of the slave control car type are executed respectively corresponding control logic.

[0051] In particular, each frame of the reconnection signal includes:

[0052] The data frame corresponding to the train type, the data frame corresponding to the train activation, the data frame corresponding to the unit train position, and the data frame corresponding to the reconnection signal; the function description of each frame is shown in the following table:

[0053]

[0054]

[0055] As shown in Figure 8 , the data conflict processing strategy is:

[0056] S2033-1, receiving signals of two train types of motor trains on the same transmission bit of the corresponding port;

[0057] S2033-2, judging whether the signal descriptions of the two train types of motor trains are consistent, if consistent, executing step S2033-3, otherwise executing step S2033-4;

[0058] S2033-3, judging whether the signal type and signal code of the two train types of motor trains are the same, if the same, executing step S2033-4; otherwise, modifying the signal code of the other train type based on the signal corresponding to the train type with more code types, and then ending the data conflict processing;

[0059] S2033-4, retaining the signals of the two train types of motor trains, and then ending the data conflict processing;

[0060] S2033-5, judging whether the signal descriptions of the two train types of motor trains are similar according to the logical function, if similar, executing step S2033-3, otherwise executing step S2033-6;

[0061] S2033-6, judging whether the passenger train motor train is defined on the transmission bit, if defined, executing step S2033-7, otherwise executing step S2033-8;

[0062] S2033-7, judging whether the signals of the two train types of motor trains affect the function of the passenger train motor train on the transmission bit according to the logical function and the definition of the freight train motor train, if not affecting, executing step S2033-4; otherwise, modifying the signal of the freight train motor train based on the signal of the passenger train motor train, and then ending the data conflict processing;

[0063] S2033-8, when the freight train motor train is defined on the transmission bit, judging whether the signals of the two train types of motor trains affect the function of the freight train motor train on the transmission bit according to the logical function, if not affecting, executing step S2033-4; otherwise, modifying the signal of the passenger train motor train based on the signal of the freight train motor train, and then ending the data conflict processing.

[0064] In this embodiment, the aforementioned transmission bits are the byte offset bits for each port, representing the positions used for data transmission on each port. Each port consists of multiple byte offset bits. WTB process data should use a 25ms transmission cycle, meaning that all WTB node process data should be sent at least once within 25ms (for paginated data, only one page should be sent). All process data should be sent at least once within 500ms. Train-level data uses a total of 128 bytes for transmission. For example, P1 / P2 consists of 48 bytes (bytes 0-47), P3 consists of 48 bytes (bytes 48-95), P4 consists of 16 bytes (bytes 96-111), and P5 consists of 16 bytes (bytes 112-127). Each byte consists of 8 bits, from bit 0 to bit 7.

[0065] Accordingly, "same transmission bit" refers to the byte offset bit on the corresponding port where the same type of data is placed, that is, the data content and data type on this transmission bit are the same or corresponding.

[0066] In this embodiment, when processing the train-level data differences in the multiple-unit data between EMUs, a comparative analysis is performed based on the train-level data transmission specifications. Protocol comparison analysis is conducted on ports P1, P2, P3, and P4 respectively. When there is a data conflict with the same offset on a certain port of the train-level data, the passenger EMU protocol is generally taken as the standard, and the passenger EMU protocol is adaptively adjusted. If a certain protocol position is unique to EMU A, and EMU B has no position in this position, through logical function analysis, it affects the train function (including control function and display information). Then, EMU B adds data according to the EMU A protocol. A and B represent two train models.

[0067] like Figure 9 As shown, the fault control strategy is as follows:

[0068] S2033-11, based on the P3 port data, determine the main control vehicle model during reconnection, and the carriage number of the main control vehicle model at the reconnection end;

[0069] S2033-12, based on the main control vehicle model during reconnection, sets up a fault dictionary; including:

[0070] When the main control model is a passenger EMU, TU1 and TU2 ports are resolved to the passenger EMU fault dictionary; TU3 and TU4 ports are resolved to the freight EMU fault dictionary.

[0071] When the main control vehicle is a freight EMU, TU1 and TU2 ports are resolved to the freight EMU fault dictionary; TU3 and TU4 ports are resolved to the passenger EMU fault dictionary.

[0072] S2033-13, according to the car number of the master control vehicle type reconnection end, marking the TU1 port, TU2 port, TU3 port, TU4 port as reconnection end or non-reconnection end, so that the man-machine interface displays the fault information of the corresponding vehicle type.

[0073] In combination with the actual operation of the reconnection combination mode, there are four reconnection scenes, as shown in Figure 10 Figure 10 (a) of FIG. 1 is: 01 car of a passenger train set and 08 car of a freight train set are reconnected; Figure 10 (b) of FIG. 1 is: 08 car of a passenger train set and 01 car of a freight train set are reconnected; Figure 10 (c) of FIG. 1 is: 01 car of a freight train set and 08 car of a passenger train set are reconnected; Figure 10 (d) of FIG. 1 is: 08 car of a freight train set and 01 car of a passenger train set are reconnected.

[0074] In this embodiment, according to the P3 port data, the master control vehicle type during reconnection and the car number of the master control vehicle type reconnection end are judged; and the vehicle type and car number of the TU1 port, TU2 port, TU3 port and TU4 port are judged, so that the man-machine interface displays the fault information of the corresponding vehicle type.

[0075] The following table is a fault information schematic table of the TU1 port, TU2 port, TU3 port and TU4 port.

[0076]

[0077] In this embodiment, through the difference processing of the data conflict processing strategy, a train level data transmission specification capable of supporting the interconnection and intercommunication of the passenger train set and the freight train set can be formed, so as to ensure that the control command of the master control vehicle can be smoothly issued to each slave control vehicle after reconnection, and the state feedback information of each slave control vehicle can also be correctly issued to the master control vehicle, so that the master control vehicle performs train level control and realizes interconnection and intercommunication.
