Data ring network is divided into inner ring and outer rings by the present invention, and host node sends failure from internal ring direction and outer shroud direction respectively
Detection messages are to the non-master on data ring network.Wherein, internal ring direction and outer shroud direction are contrary, and such as internal ring direction is inverse
During clockwise, outer shroud direction is for clockwise, certainly, when internal ring direction is clockwise direction, outer shroud direction is counterclockwise
Direction.
In actual applications, one can be selected to be host node in all nodes as needed from data ring network, it is main
Node periodically from inner ring and outer rings both direction, sends fault detect message to the non-master on data ring network, detects number
According to the link failure of looped network；Non-master receives failure inspection without from the direction of internal ring and/or outer shroud within the default time
When observing and predicting text, fault location message is generated, and host node is sent to from inner ring and outer rings both direction, to carry out to link failure
Positioning.
Fig. 1 is fault detect of the present invention, the data structure schematic diagram of positioning message, and the field of present invention needs concern is such as
Under：
Channel the type fields, it is the message for fault detect and positioning to be used to refer to the message.
Message Length fields, for indicating the length of the message, unit is bit.
Message the type fields, can be arranged as required to the field value for 0 when, represent the message for host node transmission
Fault detect message；For 1 when, represent the message for non-master generate fault location message；The field is also as needed
The type of message information of some extensions can be carried.
S fields, the field value can be set as needed for 0 when, represent the sending direction of the message for clockwise outer

It is sent to other data ring networks.
The solution of the present invention is illustrated below by particularly embodiment, Fig. 2 show data ring network failure of the present invention
Detection and the method flow diagram for positioning, including：
Step 201, receives the non-master of the message of host node transmission, and forwarding fault detect message is to host node.
First, host node needs periodically to send fault detect message to the non-master on current data looped network, described
Periodically duration can be arranged as required to, and such as host node sent primary fault detection messages every 30 minutes.
Host node needs to send fault detect message respectively to non-master from inner ring and outer rings both direction；Receive event
The non-master of barrier detection messages needs, according to the direction (internal ring direction, outer shroud direction) for receiving message, to turn to node downstream
The fault detect message is sent out, until host node.In the data ring network structure shown in Fig. 3, node 1 be host node, internal ring direction
For counterclockwise, outer shroud direction is clockwise.On the internal ring direction node 6 be the downstream node of node 1, node 5 be under node 6
Trip node, by that analogy, downstream node of the node 1 for node 2, if internal ring does not have failure, including fault detect message
Will be according to 1 (host node) → node 6 → node, 5 → node, 4 → node, 3 → node, 2 → node 1 (host node) of node on ring
Transmitted in path；In the same manner, if outer shroud does not have failure, fault detect message will be according to 1 (main section of node on outer shroud
Point) path of → node 2 → node, 3 → node, 4 → node, 5 → node, 6 → node 1 (host node) transmitted.
In view of the description of the above, it can be seen that when breaking down on data ring network, host node cannot just receive non-master section
The fault detect message that point is returned.When host node is not received by fault detect message in inner ring or outer ring, internal ring is illustrated
Or outer shroud occurs in that failure.
Step 202, is not received by the non-master of fault detect message, generates fault location message, and is sent to master
Node.
If the non-master on data ring network in addition to host node is within the default time without from internal ring and/or outer shroud side
To fault detect message is received, then fault location message is generated, and master is sent to according to inner ring and outer rings both direction respectively
Node.Wherein, the default time can be from host node transmission fault detect start of heading timing, and specific duration can be with root
It is configured according to the practical situation of data ring network, if the default time, to constantly, present node is also not received by failure
Detection messages, then generate fault location message.
When breaking down on data ring network, link failure or node failure, can cause some or multiple nodes without
Method receives fault detect message, as shown in figure 3, the link between interior node on the ring 5 and node 4 there occurs failure, then node 5
Just the fault detect message for receiving cannot be transmitted to node 4, therefore node 4, node 3 and node 2 all do not receive failure
Detection messages；Now, node 4, node 3 and node 2 each self-generating, one fault location message, and from two sides of inner ring and outer rings
To being sent to node 1 (host node).
Step 203, host node is according to the fault detect message and fault location message for receiving, the failure to data ring network
Detected and positioned.
Host node can be detected to the failure of internal ring and/or outer shroud, that is, be sentenced according to the fault detect message for receiving
Determine whether inner ring or outer ring breaks down；When internal ring is detected and/or outer shroud there is failure, host node is according to the event for receiving
Barrier positioning message is positioned to failure, that is, determine the position that failure occurs.
Below by specific embodiment illustrating fault detect message, fault location message in actual fault detect
And the application in positioning.Below in each embodiment, setting node 1 is host node, and outer shroud direction is clockwise, and internal ring direction is
Counterclockwise.
Fig. 3 is single link fault scenes schematic diagram, and as can be seen from the figure outer shroud does not break down, and node 1 can be with
The fault detect message of outer shroud direction return is received, then node 1 judges outer loop link fault-free；Interior node on the ring 5 and node 4
Between link there occurs failure, due to node 5 without normal direction node 4 forward fault detect message, node 1 cannot be from internal ring direction
Fault detect message is received, then node 1 judges that internal ring breaks down.
Then, node 1 needs the failure occurred to internal ring to carry out positioning analysises：Node 4, node 3 and node 2 be not due to having
Fault detect message is received, therefore generates fault location message, and node is sent to from inner ring and outer rings both direction respectively
1；For node 1, which has been respectively received the event that node 4, node 3 and node 2 send from internal ring direction and outer shroud direction
Barrier positioning message, illustrate on internal ring direction node 4 to the link between node 1 be it is normal, but do not receive from outer shroud direction
To the fault location message of node 5 and node 6, it is possible thereby to judge to have received fault detect in interior node on the ring 6 and node 5
Message, node 4, node 3 and node 2 are not received by fault detect message, then can determine that the failure that inner ring link occurs exists
On inner ring link between node 5 and node 4.
Fig. 4 is single node failure schematic diagram of a scenario, and node 5 there occurs failure as can be seen from Figure 4, then node 5 cannot be by
The fault detect message received from internal ring direction and outer shroud direction be transmitted to downstream node (in the downstream node in internal ring direction
For node 4, outer shroud direction downstream node be node 6), therefore, node 1 cannot receive from inner ring and outer rings direction therefore
Hinder detection messages, then node 1 can be determined that inner ring link and outer loop link all there occurs failure.
Then, node 1 carries out positioning analysises to failure：On internal ring, node 4, node 3 and node 1 cannot receive event
Barrier detection messages, therefore fault location message is generated, node 1 is sent to by inner ring and outer rings both direction；On outer shroud, section
Point 6 cannot receive fault detect message, therefore generate fault location message, be sent to section by inner ring and outer rings both direction
Point 1；For node 1, which can receive the fault location message of node 2, node 3 and node 4 from internal ring direction, can be with
The fault location message of node 6 is received from outer shroud direction, but is not all received from internal ring direction or outer shroud direction
The fault location message of node 5, illustrates that node 5 has become an isolated node.
Node 5 can illustrate two kinds of situations for isolated node, and one is that node as shown in Figure 45 is broken down in itself；One is,
When the link (link between node 5 and node 6, the link between node 5 and node 4) being connected with node 5 is broken down,
Node 1 does not receive the fault location message of node 5 only yet.
Fig. 5 is many places fault scenes schematic diagram on equidirectional ring, it can be seen that outer loop link fault-free, saves on internal ring
The link between 6 and node 5 is put, and the link between node 4 and node 3 there occurs failure, then node 1 cannot be from internal ring side
To fault detect message is received, judge that inner ring link breaks down.
Then node 1 carries out positioning analysises to inner ring link failure, as node 5, node 4, node 3 and node 2 cannot
Fault detect message is received, then this each self-generating fault location message of four nodes, and sent from inner ring and outer rings both direction
To node 1；For node 1, as outer loop link is normal, and which can receive node 5, node 4, section from outer shroud direction
The fault location message of point 3 and node 2, illustrates only have node 6 to have received fault detect message on internal ring, it is possible thereby to determine
Inner ring link between node 6 and node 5 necessarily there occurs failure；Meanwhile, node 1 can only receive node 2 from internal ring direction
With the fault location message of node 3, if the link between node 4 and node 3 is normal, node 1 should be received
The fault location message of node 4, but but it is not received by, thus may determine that the link between node 4 and node 3 is necessarily sent out
Failure is given birth to；And for whether the inner ring link between node 5 and node 4 breaks down, not can determine that herein.
Fig. 6 is many places fault scenes schematic diagram on different direction ring, it can be seen that between interior node on the ring 6 and node 5
Link there occurs failure, and the link between outer node on the ring 4 and node 3 there occurs failure, therefore, node 1 is in inner ring and outer rings
Fault detect message cannot be all received in both direction, it is possible to determine that inner ring link and outer loop link all there occurs failure.
Then, node 1 carries out positioning analysises to failure：Can determine node 2, node 3, node 4, node 5 and node 6 all
Need to generate fault location message, and node 1 is sent to by inner ring and outer rings both direction；For node 1, which is from interior
The fault location message of node 5, node 4, node 3 and node 2 is received only on ring direction, it is possible thereby to determine on internal ring direction
Node 5 to the link of node 1 be normal；The failure which can receive node 4, node 5 and node 6 from outer shroud direction is fixed
Position message, it may be determined that on outer shroud direction node 4 to the outer loop link between node 1 be normal.
The fault location message received from inner ring and outer rings both direction is analyzed by node 1, it is known that such as
Fruit inner ring link is normal, then node 1 can also receive the fault location message of node 6, but reality is but not received by, can
To determine that node 6 there occurs failure to the inner ring link of node 5, but cannot determine for the internal ring between node 1 and node 6
Whether link breaks down；If outer loop link is normal, node 1 can also receive the fault location report of node 2 and node 3
Text, but reality is but not received by, it may be determined that and the link between node 3 and node 4 there occurs failure, but can not
Determine whether node 1 breaks down to the outer loop link between node 3.
