    [0035] Currently, a train communication network (TCN) is installed in a train, so that the power units in the train can interact via the TCN.
    [0036] When the TCN fails and cannot work, the power units cannot communicate with each other, therefore the electrical equipment in the train cannot work normally.
    [0037] Ethernet has a fast transmission speed and can transmit more information, thus, Ethernet is applied to a train control network. In the technical solutions of this disclosure, a train-level Ethernet and a train communication network are used in a train simultaneously, to ensure that a mature and reliable network system is applied to the train. Thus, a redundant network structure is formed by the train-level Ethernet and the train communication network, thereby improving the communication stability and reliability between the train power units.
    [0038] Embodiment one
    [0039] Reference is made to Figure 1, which is a schematic structural diagram of a train network control system according to one embodiment of the present disclosure. The train network control system provided in this embodiment has at least two power units, and data interaction is performed between the at least two power units through an Ethernet backbone network (not shown in Fig. ) or a wired train bus (not shown in the figure).
    [0040] A train-level network consists of the wired train bus and the Ethernet backbone. A vehicle-level network includes a ranking network and a multi-function vehicle bus.
    [0041] Take the example of electric multiple units. For example, electrical multiple units have eight bays, with bays 1 through 4 forming one power unit and bays 5 through 8 forming another power unit. Information can be transmitted between the two PSUs via the Ethernet Backbone (ETB) or the Wired Train Bus (WTB). Information can be transmitted inside a power unit via the Vehicle Level Rating Ethernet (ECN) or Multi-Function Vehicle Bus (MVB).
    [0042] In the embodiment, ETB and ECN can form Ethernet (ETH), and WTB and MVB can form Train Communication Network (TCN).
    [0043] When a first supply unit in the train needs to send a control instruction to another supply unit, the first supply unit is configured to perform the following steps 1 to 3:
    [0044] step 1 of obtaining address information from the other PSU;
    [0045] step 2 of sending a control instruction to the power supply unit corresponding to the address information through the Ethernet backbone based on the address information; and
    [0046] the step 3 of sending a control instruction to the other power supply unit via the wired train bus in the case of not receiving feedback information from the power supply unit corresponding to the information address within a predefined period.
    [0047] In the aforementioned step 1, the address information represents an IP address of the other PSU in the Ethernet backbone network and wired train bus.
    [0048] In step 3 above, the preset delay can be 50 milliseconds, or can be set to other values.
    [0049] Each power unit includes a central control unit (CCU), a gateway, and a controlled device, and the power unit is configured to control the controlled device.
    [0050] The central control unit is connected to the gateway, and the gateway is connected to a gateway of another power supply unit via the wired train bus.
    [0051] The central control unit is connected to the controlled device via the classification Ethernet and the multifunction vehicle bus.
    [0052] Controlled devices are connected to each other via Ranking Ethernet and Multi-Function Vehicle Bus.
    [0053] The central control unit and the controlled device are connected to a central control unit and a controlled device of another power supply unit via the ranking Ethernet and the Ethernet backbone network connected to the ranking Ethernet.
    [0054] The central control unit is configured to send a control command to the controlled device via the filing Ethernet, and to send a control command again to the controlled device via the multi-function vehicle bus in the case of not receiving a feedback information from the controlled device within a preset time.
    [0055] Controlled device refers to an electrical equipment or system host connected to the central control unit in the power supply unit. The central control unit controls the electrical equipment or the system host.
    [0056] The system host can be a controlled device such as a traction control device, a brake control device, a door control device and an air conditioning control device.
    [0057] When the central control unit of the first power supply unit needs to send a control instruction to the central control unit of another power supply unit, the central control unit of the first power supply unit is configured to send, based on address information of the other power supply unit, a control instruction to the central control unit of the power supply unit corresponding to the address information via the backbone network ethernet. In the case of not receiving feedback information from the power unit corresponding to the address information within the preset time, a control instruction is re-sent to the power unit corresponding to the address information. address via the wired train bus.
    [0058] According to the train network control system provided by this embodiment of the present disclosure, data may be transmitted between power units in the train via the Ethernet backbone network or the wired train bus. Both networks operate simultaneously. Each power supply unit is preferably controlled via the Ethernet backbone network. When the Ethernet backbone fails, the wired train bus is used for data transmission. The wired train bus serves as passive redundancy for the Ethernet backbone network. Alternatively, the wired train bus can be preferentially used. When the wired train bus fails, the Ethernet backbone network is used for data transmission. Thus, the Ethernet at the train level serves as a passive redundancy for the train communication network.
    [0059] The overall topology of the two different networks is the same. The train network control system defines the network segment according to the power unit, and the address information of different devices in a power unit can be set in a network segment. Data transmission between PSUs is done through the Ethernet backbone network and the wired train bus. Data transmission in a power unit is carried out via filing Ethernet and the multi-function vehicle bus. The data transmission mode of the network at the train level is the same as the data transmission mode of the network at the vehicle level.
    [0060] The same communication protocol can be used for Ethernet and the wired train bus for information interaction between central control units of power units. Each central control unit preferentially uses the Ethernet backbone network for information interaction. When communication between central control units via the Ethernet backbone network fails, the wired train bus is used for information interaction. The central control unit in each power unit integrates data into the power unit. The embedded data is transmitted to the Ethernet backbone network connected to the power supply unit's central control unit via filing Ethernet, and then transmitted to other power supplies via the Ethernet backbone network.
    [0061] Control by the central control unit in each power supply unit can be realized using relevant data according to actual situations.
    [0062] The information interaction between the central control unit and the controlled device in the power unit uses multi-function vehicle bus and Ethernet communication protocols with the same content. The Ethernet uses a TRDP protocol, and other systems in the train use TRDP and MVB protocols to perform data interaction with the central control unit.
    [0063] A train including the aforementioned train network control system is further provided according to this embodiment of the present disclosure.
    [0064] According to the train network control system and the train provided by this embodiment of the present disclosure, the Ethernet backbone network and the wired train bus are provided in the train, the data interaction between each of the units of Power provided in the train can be carried over the Ethernet backbone network and the wired train bus. In conventional technology, the central control units of the power supply units cannot communicate with each other when the train's train communication network fails. However, in current solutions, the central control units of the power units can communicate with each other via the wired train bus when the Ethernet backbone fails, and the central control units of the power units can communicate with each other. them through the Ethernet backbone network when the wired train bus fails. The Ethernet backbone network and the wired train bus form a redundant network structure, improving the stability and reliability of communication between train power units.

    [0067] step 200 of obtaining address information of another power supply unit by a first power supply unit;
    [0068] step 202 of sending a control instruction to a power supply unit corresponding to the address information via the Ethernet backbone based on the address information.
    [0069] the step 204 of sending a control instruction to the other power supply unit via a wired train bus in the event of not receiving feedback information from the power supply unit corresponding to the information address within a predefined period.
