Position information determines the fault condition for sending the first ETBN board of topology information of control equipment to be controlled, can specifically execute are as follows: control
Device processed is according to formulaDetermine Ethernet mesh information binary piece of information and default same type report
Comparison result d (the x of the binary piece of information of texti,yi), wherein xiFor the message of preset i-th seed type, yiFor indicating
The message of the i-th seed type obtained, αpFor indicating xiBinary piece of information, βqFor indicating yiBinary piece of information, p
=0,1 ... n-1, q=0,1 ... n-1, n is for indicating xiAnd yiNumber of encoding bits,For indicating exclusive or；Controller is according to d
(xi,yi) size relation with 0, determine the fault condition for sending the first ETBN board of topology information of control equipment to be controlled.
Optionally, d (xi,yi) for measuring the consistency of message, indicate the received hello packet of controller institute and pre-
If standard hello packet between difference, numerical value reflect mistake number of bits.Controller will be calculated
d(xi,yi) foundation as fault diagnosis, if d (xi,yi)=0, then it is assumed that received hello packet and standard
Hello packet content is consistent, sends the ethernet device fault-free of the hello packet.
If d (xi,yi) it is equal to 0, it is determined that the first ETBN board fault-free；If d (xi,yi) it is not equal to 0, it is determined that
First ETBN board may break down.
It should be noted that controller can with real time parsing ethernet device send hello packet be transmitted two into
Meaning expressed by message structure processed, including being parsed to the application layer data inside hello packet, in the embodiment of the present application
In be the fault diagnosis functions for illustrating controller by taking the Ethernet mesh information that controller receives as an example, that is to say, that control
Device processed is to the executable fault diagnosis functions of the hello packet received.
Specifically, can be stored in advance in the controller inside the type of message and corresponding message of hello packet
X={ x can be used in binary piece of information1,x2,…,xNIndicate type of message；The report for the hello packet that controller receives
Y={ y can be used in literary type1,y2,…,yNIndicate.Wherein, x1With y1, x2With y2, xNWith yNFor indicating the report of same type
Text, N are the type of message quantity of pre-stored hello packet.Controller determine the type of hello packet that receives with
And after binary piece of information, it can useDetermine the hello packet received and default same type
Hello packet binary piece of information comparison result, and then determine send hello packet ethernet device failure feelings
Condition.
Optionally, if controller detects the sub- device fails of network control system, capable of emitting warning information is prompted
Train crews detect corresponding faulty equipment, to improve the processing effect of the sub- equipment fault of network control system
Rate.
Step 204, controller generate control signal according to the topology information of control equipment to be controlled；It sends and controls to control equipment to be controlled
Signal processed.
In the embodiment of the present application, ETBN board is set in train network control system, is organized into groups automatically using ETBN board
Ethernet, and the topology information for the ETBN board being arranged in every section train is obtained, such controller can be according to ETBN board
The topology information of acquisition generates control signals to control control equipment to be controlled.It, also can be certainly in this way when train length changes
Dynamic networking Ethernet, realizes the control to equipment to be controlled, improves train network control system self-adaptive grouping Ethernet
Ability.
