Based on the above embodiment, further, other interchangers are obtained in the first interchanger to be inquired according to switch device
After the response message for the address information including interchanger that information returns, the method also includes：
Under operating status at the beginning of train, train network Topology Discovery Protocol report is passed through according to the address information of the interchanger
Literary and other interchanger interactive information, obtain the topology information of other interchangers；
Under end of run state at the beginning of train, the master control list of train is sent to by the topology information that control bus will acquire
Member.
Specifically, when running at the beginning of train, all devices information of switch query Home Network intersegmental part passes through train network
Topology Discovery Protocol message TTDP message and other interchanger interactive information, after first end of run, interchanger is formed whole
Then the train topology information of vehicle notifies the first end of run of the main control unit of train, and will change train topology information and carry out with it
Interaction.Wherein, just operation is also known as configuration, is carried out before train network normal work, special when train, which forms, to be changed
It is not each vehicle mounting or Xie Lianshi, bus will re-start just operation operation.It during train operation, can also be with
When operation just run according to the artificial progress of needs of application.The topology information of vehicle can be sent in operation at the beginning of train
Train main control unit provides technical foundation for the dynamic marshalling reconciliation volume of train.
Fig. 3 is the schematic diagram of train network Topology Discovery Protocol message, and referring to Fig. 3, train topology information content includes：It hands over
Change the first operating status of UUID (Universally Unique Identifier), interchanger itself, the exchange of the fixed net of itself
The number of interchanger, the traffic direction of train network, network list of subnet etc. in the ID number of machine itself, network.
The relevant information that each interchanger of message specified in more detail when transmitting message needs to fill in messages.In train
Just when operation, by mutually transferring information between interchanger, the TTDP message of the train is ultimately formed.The TTDP of each interchanger
The fixation train table topology information of message is all consistent, and difference is in preceding several information relevant to ETB itself of message
Hold.After topology information is formed, init state mark in TTDP message and update mark will set, show train just
End of run, and train topology changes, and main control unit is needed to update train information.
Further, the method also includes：First interchanger passes through control bus and remote according to User Datagram Protocol
Communication interaction is carried out between end equipment.
Specifically, train Reliable User Datagram Protocol TRDP agreement (Reliable--UDP) is one based on UDP/IP
The reliable network communication pool of agreement.The design principle of RDP refers to Transmission Control Protocol, allows the application to obtain in UDP layer similar
General, the reliable data transmission capabilities of TCP.Fig. 4 is the realization principle schematic diagram of train Reliable User Datagram Protocol, is such as schemed
Shown in 4, realized by User Datagram Protocol UDP service.TCP/IP is most basic transmission control protocol, basic herein
It is upper that remote equipment directly to is disposably sent message by UDP, without setting up connection, guarantee real-time communication requirement.This
The invention Real-time Communication Technology is the communication technology that original standard ethernet technology does not have.The real-time control of train is wanted
Ethernet is asked to overcome the drawback of original real-time difference, which realizes reality by UDP on the basis of TCP/IP, in link layer
When communication protocol, application layer transmit real time communication data.
Further, the method also includes：If the judgement of the first interchanger knows that itself breaks down, and starts bypass mould
Formula is by itself short circuit, so as to continue communication interaction between other interchangers.
Specifically, bypass mode Bypass technology is to be formed that there is the Ethernet of Bypass function to connect by bypass relay
Mouthful, which will be connected to the train bus-line ETB network of Ethernet, and bypass is exactly can be (disconnected by specific triggering state
Electricity crashes) allow two networks not by the system of Network Security Device, and be directly physically connected, so there is Bypass
Afterwards, after Network Security Device failure, the network mutual conduction being connected in this equipment can also be allowed.The present embodiment is realized
Bypass technology, has been turned up the reliability of network, meets the reliability requirement of train network system.It is of the present invention
Bypass technology is a kind of technology for improving interchanger reliability itself.In the network structure of bus-type, interchanger itself goes out
Existing failure, will mask oneself on rigid line by this technology, to keep the unimpeded of route.Concrete methods of realizing is exactly event
When barrier, is imported and exported by the Ethernet of relay short circuit oneself, oneself is masked from whole network, does not influence other equipment
Normal communication.
