And the information such as FTU.
In step s 102, whether monitoring looped network meets multipoint fault condition；
For distribution optical fiber ring network, some interchangers included in looped network, generally only one is Master Mode
Switch (holotype), other are Transit Mode Switch (slave pattern)；The interchanger or main website of holotype and its
Include some communication links between the looped network node of the interchanger formation of his slave pattern, and between node and node, if described
Dry communication link at least includes that the link of loop network control message and looped network business message can be carried.Loop network control message has many
Kind, its purpose be mainly realize whole network physics cyclization and logic is not cyclic, while monitor looped network health status and
The switching of looped network；Looped network business message mainly carries three remote sensing informations between the power distribution network terminals such as DTU, FTU, TTU and station end, three
Remote sensing information is interacted by 104 or 101 agreements.
As shown in figure 1, loop network control message, is sent by the master port 41 of main website 4, after each node in looped network, by
Main website 4 is withdrawn from port 42；When looped network is normally run, looped network business message is only in the master port 41 of main website 4 and last
Communicated between the master port of individual node.For example, in Fig. 1, master port 41 and threeth node 3 of the looped network business message in main website 4

Isolated island described herein refers to node that can not be with master station communication.One or more phases can be included in isolated island
Node even.For example, in fig. 2, the failure of " No. 5 points " is not repaired and occurs " No. 6 points " failure, then now, main website 4
Information exchange can only be carried out with the 3rd node 3, first node 1 and Section Point 2 turn into isolated island.
Certain node is determined after isolated island, test packet is sent to the adjacent node of isolated island at isolated island, as shown in figure 3, such as
Fruit determines that the 3rd node 3 is isolated island, then sends test packet to first node 1 and fourth node 4 at the 3rd node 3, be not difficult
Understand, if first node 1 and fourth node 4 receive test packet, illustrate between the node 3 of first node 1 and the 3rd, and
There is no fiber cut failure between the node 3 of fourth node 4 and the 3rd.On this basis, first node 1 and fourth node 4 again will tests
Message is sent to other each adjacent nodes, unsuccessful until sending.For example, the test packet is sent to by fourth node 4
After the 5th node (being omitted in figure) adjacent thereto, the 5th node does not receive the test packet, that is, sends unsuccessful, therefore
Determine there is fiber cut failure between the node of fourth node 4 and the 5th, it is island boundaries to determine fourth node 4.Similarly, it may be determined that first
Whether node is island boundaries, is repeated no more here.
In step S105, according to the isolated island and the corresponding mirror image data of the island boundaries, the event of looped network multiple spot is determined
Hinder position.
Isolated island node and the corresponding mirror image data of island boundaries node are analyzed, is handed over according to node can be embodied in mirror image data

In step s 201, judge that whether main website receives the time interval of loop network control message more than predetermined threshold value；
As described above, loop network control message is sent by the master port of main website, after each node in looped network, by main website
From port withdraw, make looped network physics cyclization and logic is not cyclic.Include between each node in looped network some for data transfer
Link.It is understood that the time interval that main website receives loop network control message has certain allowed band or default threshold
Value.
In step S202, if the time interval that main website receives loop network control message is more than predetermined threshold value, looped network is received
Service message；
When looped network information transfer state is normal, looped network business message can only main website master port and last node
Master port between communicate, main website can not receive looped network business message from port.Based on this, when main website receives loop network control report
When the time interval of text is more than predetermined threshold value, looped network business message is received so that main website can receive looped network simultaneously from port
Control message and looped network business message.
On the basis of above-mentioned steps S202, in step S203, judge whether the looped network business message that main website is received subtracts
It is few；
When the information transfer state of looped network is normal, the looped network business message that main website is received should be included from institute in looped network
The quantity for having the service message of node, i.e. service message should be corresponding with the number of looped network interior nodes.
Therefore, in step S204, if the looped network business message that main website is received is not reduced, determine that looped network is unsatisfactory for multiple spot
Fault condition；
If the looped network business message that main website is received is not reduced, i.e. the quantity phase of the quantity of service message and looped network interior nodes
Matching, illustrate each node and its between link communication normally, determine that looped network is unsatisfactory for multipoint fault condition.
On the contrary, in step S205, if the looped network business message that main website is received is reduced, determining that looped network meets multiple spot event
Barrier condition；
When the looped network business message that main website is received is reduced, i.e., the quantity of the quantity of service message and looped network interior nodes is not
Match somebody with somebody, the quantity of service message is less than interstitial content, determines that looped network meets multipoint fault condition.
The method whether the monitoring looped network that the embodiment of the present application is provided meets multipoint fault condition, by whether monitoring looped network
Meet multipoint fault condition and whether the communication of indirect monitoring looped network is abnormal, when looped network meets multipoint fault condition, perform at once

In step S301, if the mirror image data includes the message that main website is issued, the mirror image data pair is determined
The node answered is not isolated island；
In step s 302, if not including the message that main website is issued in the mirror image data, the mirror image data is determined
Corresponding node is isolated island.
Fig. 7 is that the corresponding node of determination mirror image data according to further example embodiment is isolated island method flow
Figure, in other words, Fig. 7 shows the refinement step of step S302 shown in above-mentioned Fig. 6, including：
Step S401, interchanger instruction of restarting is sent to the corresponding node of the mirror image data；
It is worth noting that, the application is analyzed according to the corresponding mirror image data of each node, fault bit is finally determined
Put, still, when in mirror image data not include main website issue message when, however not excluded that be node switch or nodal terminal failure
Situation.Based on this, if not including the message that main website is issued in mirror image data, interchanger instruction of restarting is sent to the node,
The interchanger instruction of restarting is used to make node switch execution restart action.
And step S402, if restarting the node mirror image data after interchanger does not include the message that main website is issued, it is determined that
The corresponding node of the mirror image data is isolated island.
If restarting the node mirror image data after interchanger does not still include the message that main website is issued, node can be excluded
Exchange fault causes communication abnormality, thus determines that the node is isolated island.
