Outside the transmission network, the voice switch of the core network is accessed, because of the existence of the transmission network, the signal switching can be carried out between the two switches, and the network formed by connecting different switches is called as the switching network from the service perspective. When a user is in a call or transmits a data signal, the terminal device is accessed to the switch through a local access network, so that the receiving and sending of the signal are realized, and a part of networks accessed by the user is called an access network in service.
In order to ensure the stable operation of the system, when an alarm occurs on the switch device of the core network, the alarm needs to be processed to recover the communication service, and the key of the alarm processing is processing after reason analysis, and from the current management and maintenance, the communication needs to be distinguished from a pipeline network (managing communication network resources related to the optical cable), a transmission network, a switching network and the like. Because the function difference between different network devices is large, and a plurality of devices have strong speciality, the management is separately maintained according to the speciality. However, in the operation process, all specialties can influence each other, in the equipment alarm processing process, the actual association relation of the network is very important for alarm analysis, and the recovery speed of the alarm can be greatly improved through automatic analysis processing.

Specifically, when the judgment result is a fault caused by fiber core interruption, for a monitored fiber core, the fiber core interruption position can be automatically obtained through monitoring the fiber core, GIS position information of fiber core interruption is calculated according to the position, if the fiber core network is not monitored, after the system analyzes that the fiber core interruption fault exists, the fiber core interruption position can be tested by using an OTDR tool and then is backfilled into the system, and the GIS position information of fiber core interruption is calculated again by the system.
Fig. 8 is a schematic structural diagram of an automatic analysis device for alarm messages of a core network switch for positioning faults of an optical cable according to the present invention.
Specifically, assume that a fault occurs on the cable 1 and occurs x meters from the a-end of the cable 1 (assuming that the location is between the manhole 2 and the manhole 3 of the cable 2).
Finding the bearing relation of the transmission segment 1 through the bearing relation:
judging whether the jump fiber 1 has a fault: x > n1
Judging whether the jumper connection 1 fails: x > n1+ n2
Judging whether the optical cable 1 is in fault: x > n1+ n2+ n3
Judging whether the jumper connection 2 fails: x > n1+ n2+ n3+ n4
Judging whether the optical cable 2 is in fault: x > n1+ n2+ n3+ n4+ n5, which is incorrect, indicating that a fault has occurred on the cable 2.
Locating the specific fault location of the optical cable 2:
judging whether the fault is on the pipeline 1: x-n1-n2-n3-n4> m1
Judging whether the fault is left in the well 1: x-n1-n2-n3-n4> m1+ m2
Determine if the fault is on the pipe 2: x-n1-n2-n3-n4> m1+ m2+ m3
Judging whether the fault is in the plate of the manhole 2: x-n1-n2-n3-n4> m1+ m2+ m3+ m4
Judging whether the fault is on the pipeline 3: and x-n1-n2-n3-n4> m1+ m2+ m3+ m4+ m5, wherein the step is wrong, and the fault is indicated to occur on the pipeline section 3.
The specific information of the GIS is positioned,
from the above calculation, it can be known that the fault occurred on the pipe 3 at a distance of (x-n1-n2-n3-n4-m1-m2-m3-m4) meters from the A end
According to the length, GIS positioning calculation of the pipeline section can be realized, and therefore the specific fault position is displayed on a GIS map.
