Description
Technical Field
The embodiment of the invention relates to the technical field of optical communication, in particular to a method and a device for monitoring optical cable faults.
Background
With the rapid increase of traffic, optical fiber communication has been vigorously developed due to its huge communication capacity, and the scale of an optical fiber network, which is the basis of optical fiber communication, has also been continuously expanded. With the continuous expansion of the scale of the optical cable network, the optical cable faults are more frequent, and the prior art does not have an intelligent means for monitoring the optical cable faults and the whole process of processing the optical cable faults.
The optical path is used as a logic concept, and in the transmission profession, specifically refers to a link in which optical interfaces of two transmission network elements are butted in a transmission network management. The most important index for characterizing the performance of an optical path is optical power, and one optical path generally relates to 4 optical power performance values, namely, a-end luminous power, a-end receiving optical power, a Z-end luminous power and a Z-end receiving optical power. The physical entity for carrying the optical path is then the core of the optical cable. Generally, one optical path occupies two fiber cores in one optical cable, namely, a-transmission and Z-reception occupy one fiber core, and Z-transmission and a-reception occupy the other fiber core. Because the physical entity bearing the optical path is the optical cable fiber core, the performance condition of the optical cable fiber core can be judged by using the 4 optical power performance values related to the optical path, and the more optical paths can be used, the more optical cable fiber cores can be used for judging the performance condition.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic flow chart of a method for monitoring an optical cable fault according to an embodiment of the present invention, as shown in fig. 2, the method includes:
Specifically, when the optical cable is interrupted or a part of the fiber core is damaged, all or part of the optical paths carried by the optical cable are also interrupted, and an optical path interruption alarm is generated at the same time, the generated optical path interruption alarm is sent to the comprehensive alarm platform from the transmission network manager, the optical path interruption alarm can be extracted by opening an interface between the transmission network manager and the comprehensive alarm platform, the acquisition of the optical cable fault triggering condition can be realized by extracting the content of EMS (enhanced management system), managed element and PTP (precision time protocol) fields in the optical path interruption alarm information and combining with the acquisition of the current optical power value of a relevant port by calling a CORBA interface, and the acquisition of the optical cable fault triggering condition is realized by deploying an optical cable fault triggering condition acquisition algorithm module in the optical power.
The embodiment of the invention relates to the acquisition of a current optical power performance value of a port by utilizing a getAllCurrentPMData interface model in a CORBA interface.
Fig. 3 is a schematic flow chart of an optical cable fault triggering condition obtaining algorithm provided in the embodiment of the present invention, and as shown in fig. 3, specific implementation steps are as follows:
step a, continuously receiving transmission type alarms from the comprehensive alarm platform and detecting light path interruption alarms in the transmission type alarms.
The light path interruption alarm to be detected in this step includes MUT _ LOS (hua ye), input no light alarm (zhongxing), ILS (beacon fire), OLP R1 (optical line), and OLP R2 (optical line).
And step b, when the light path interruption alarm is detected, recording all the detected light path interruption alarms.
This step requires recording all light path interruption alarms within 3 minutes from the first detected light path interruption alarm.
And c, randomly selecting one from the recorded light path interruption alarms, extracting the contents of the EMS, the managed element and the PTP in the alarm information, utilizing the contents of the three fields to present a network resource table for matching, calling a CORBA interface to acquire the current luminous power value of a corresponding luminous port (a Z transmitting port or A transmitting port) if one luminous port (A receiving port or Z receiving port) in the present network resource table can be matched, discarding the alarm if one luminous port in the present network resource table cannot be matched, and repeating the step after deleting the light path interruption alarm in the recorded light path interruption alarm.
And d, judging whether the difference (absolute value) between the current light-emitting power value of the light-emitting port acquired by calling the CORBA interface in the step c and the historical light-emitting power value is less than 3dB (namely judging whether an optical cable fault event triggering condition is met), if so, triggering an optical cable fault event and outputting the bearing optical cable field content corresponding to the light-receiving port matched in the step c in the current network resource table, if not, discarding the alarm, and repeating the step c after deleting the alarm in the recorded optical path interruption alarm.
The historical optical power value of a certain port related in the step is obtained by calculating an average value of example optical power values of the same port for nearly 7 days after removing obvious difference items, wherein a difference threshold value is set to be 1 dB. The optical cable fault triggering condition obtaining algorithm module needs to record the alarm occurrence time of the optical path alarm for triggering the optical cable fault as the fault occurrence time and the alarm clearing time of the last clearing of all the recorded optical path interruption alarms as the fault recovery time besides obtaining the optical cable fault triggering condition, and outputs the fault recovery time to the automatic editing module.
In the embodiment of the invention, the total quantity of the transmission current network resources is counted according to the fields shown in the table 1 to form a current network resource table, and the table needs to be updated in time according to the change condition of the current network.
It should be noted that when a CORBA interface is called to acquire a current optical power performance value, a certain parameter needs to be input, the OMC server address field content in table 1 is used for communication, the EMS name field content is used for informing a currently docked network management object, the managedielement field content is used for informing a network element object in a currently docked network management system that needs to perform current optical power performance acquisition, the PTP field content is used for informing a physical port object that needs to perform current optical power performance acquisition, and the pmParameters field content is used for informing whether the current acquisition is light emitting power or light receiving power. In summary, the process of acquiring the current optical power of the specific port by calling the CORBA interface includes first finding a network management system (EMS), then finding a specific network element (managed element) in the network management system, then finding the specific port (PTP) under the network element, and finally extracting the current optical power or the light emitting power of the port according to the pmParameters parameter. The optical path information comprises an optical path name, contents of a transmission system and a main field and a standby field, and collected current light receiving and transmitting power values at two ends of the optical path.
TABLE 1 present network resource List
Fig. 4 is a schematic diagram of an algorithm flow for analyzing and determining an optical path interruption condition and a fault optical cable section according to an embodiment of the present invention, as shown in fig. 4, a specific flow for analyzing an optical path interruption condition and determining a fault optical cable and a fault optical cable section according to an embodiment of the present invention is as follows:
the content of the bearer cable field output from the previous step may comprise one cable segment or may comprise a plurality of cable segments. If the content of the field of the optical cable carrying only contains one optical cable section, the optical cable section is directly judged as the optical cable section with the current fault. Then, a CORBA interface is called to collect current light receiving and emitting power values of two ends of all light paths including the optical cable section in the bearing optical cable, so that the specific light path interruption condition is analyzed and determined through the current light power values of the ports. For example, if at least one of the current received/emitted light power values is smaller than a first preset threshold value (-30dBm), it is determined that an interrupt has occurred.
If the carrier optical cable comprises a plurality of optical cable sections, a CORBA interface is called to collect current light receiving and emitting power values of two ends of all optical paths comprising the optical cable sections in the carrier optical cable, and a specific optical path interruption condition is analyzed and determined through a port current optical power value, if at least one of the current light receiving and emitting power values is smaller than a first preset threshold value, the interruption is determined to occur. And after the specific optical path interruption condition is determined, judging the currently failed optical cable section by analyzing the optical cable sections commonly owned in the optical cable field content carried by all the interrupted optical paths, if only one optical cable section commonly owned, directly judging the optical cable section as the currently failed optical cable section, and if a plurality of optical cable sections commonly owned, all the optical cable sections are listed as optical cable sections which are possibly failed. The analysis and determination process may refer to the optical path interruption condition and faulty optical cable segment analysis and determination algorithm flow shown in fig. 4, and the specific function is implemented by deploying an optical path interruption condition and faulty optical cable segment analysis and determination algorithm module in the optical power management system.
On the basis of the above method embodiment, the method further comprises the steps of: and periodically calling a CORBA interface to acquire the current optical power values of all the light receiving ports and the light emitting ports in the current network resource table, and recording the current optical power values in an optical power database. Specifically, the port optical power test implementation flow is as follows: the method comprises the steps of acquiring current optical power values of all ports in a current network resource table by calling a CORBA interface at a fixed point every day and recording the current optical power values in an optical power database to realize port optical power sampling, wherein sampling inspection is realized by deploying a sampling inspection module in an optical power management system. The data storage period of the optical power database can be set according to actual requirements, and the data storage period is set to be 60 days. For example, the measured port optical power value is used as the port historical optical power value after certain calculation.
On the basis of the embodiment of the method, the embodiment of the method also relates to the automatic fault short message issuing by utilizing the event management platform and the automatic fault voice reminding by utilizing the IVR platform, wherein the flow of automatically issuing the fault short message is as follows:
acquiring the alarm occurrence time of the optical path interruption alarm, and automatically modifying a preset fault attention short message template to generate a fault attention short message according to the alarm occurrence time, the optical path information and the optical cable paragraph name; and sending the fault attention short message and the short message number list to be sent to an event management platform so as to enable the event management platform to carry out short message group sending.
Specifically, the automatic editing of the fault message can be realized by presetting a fault attention message template, and automatically modifying corresponding variables in the preset fault attention message template according to the alarm occurrence time of the optical path interruption alarm for triggering the optical cable fault, the optical path interruption condition and the optical path names of all optical paths judged to be interrupted, the content of the three fields of the transmission system, the primary field/the standby field and the optical cable section name judged to be faulty or possibly faulty, which are output by the faulty optical cable section analysis and judgment algorithm module. The method comprises the steps of calling an interface between the event management platform and the event management platform, transmitting a fault attention short message and a short message number list (the number list is also configured in advance) which is generated by automatic editing to the event management platform, and automatically calling a network delivery short message interface after the event management platform receives a short message to be sent and the short message number list to be sent and sending the content of the short message to a short message center for group sending through a PP protocol.
The flow of automatically carrying out fault voice reminding by using the IVR platform is as follows:
acquiring the alarm occurrence time of the optical path interruption alarm, and automatically modifying a preset fault voice reminding content template to generate fault voice reminding content according to the alarm occurrence time, the optical path information and the optical cable paragraph name; and sending the fault voice reminding content and the number list needing voice reminding to an IVR platform so that the IVR platform can automatically broadcast the fault voice reminding content after dialing the number list.
Specifically, the fault voice prompting content automatically modifies corresponding variables in the preset fault voice prompting content template to realize automatic editing of the fault voice prompting content according to the alarm occurrence time and the optical path interruption condition of the optical path interruption alarm for triggering the optical cable fault and the optical path names of all optical paths judged to be interrupted, the content of the three fields of the transmission system and the primary/standby and the name of the optical cable section judged to be faulty or possibly faulty, which are output by the fault optical cable section analyzing and judging algorithm module. And (3) opening an interface between the IVR platform and the fault voice reminding content and a number list needing voice reminding, wherein the fault voice reminding content and the number list needing voice reminding are generated by automatic editing, the IVR platform receives the fault voice reminding content and the number list needing voice reminding (the number list is also preset), then numbers on the number list are automatically dialed (the number of redialing times is set to be 3), and the fault voice reminding content is automatically broadcasted (the broadcasting times is set to be 2) after the other party answers. The above functions are specifically realized by deploying an automatic editing module in the optical power management system.
Fig. 5 is a schematic view of a process of controlling the repair quality of the optical cable according to the embodiment of the present invention, and as shown in fig. 5, on the basis of the foregoing method embodiments, the process of controlling the repair quality of the optical cable according to the embodiment of the present invention includes: and calling the CORBA interface to acquire the transceiving optical power values at the two ends of the repaired optical path, comparing the transceiving optical power values with the historical optical power value of the optical path, and determining that the repair is successful if the absolute value of the difference value of the transceiving optical power values and the historical optical power value of the optical path is smaller than a second preset threshold. Specifically, the optical cable repair quality is directly embodied in the optical power at the two ends of all optical paths carried by the optical cable repair quality, so that the control of the optical cable repair quality can be realized by comparing the repaired optical power receiving and transmitting values at the two ends of all optical paths carried by a fault optical cable section with corresponding historical optical power values, wherein the historical optical power values are obtained by calculating an average value after removing obvious difference items (the difference threshold value is set to be 1dB) in optical power values of nearly 7 days, the repaired optical power receiving and transmitting values at the two ends are obtained by calling a CORBA interface to automatically collect, and the optical power difference values are also obtained by automatic calculation. The whole optical cable repair quality control process is shown in fig. 5, wherein the rest processes except the telephone notification are still performed manually and are realized in an automated manner, specifically, by deploying an optical cable repair quality control module in the optical power management system.
After the repair, the embodiment of the invention also provides a fault recovery short message automatic editing and issuing process, acquires the alarm clearing time when the repair is successful, and automatically modifies a preset fault attention short message template to generate a fault recovery short message according to the alarm clearing time, the optical path information and the optical cable paragraph name; and sending the fault recovery short message and the number list to be sent of the short message to an event management platform so as to enable the event management platform to carry out short message group sending.
Specifically, the fault recovery short message can be edited and sent after the optical cable is repaired. The editing and issuing process of the fault recovery short message is basically the same as that of the fault attention short message, namely, the automatic editing of the fault recovery short message is realized by adopting a preset short message template and correspondingly modifying variables in the template, wherein the fault recovery time is the alarm clearing time of the last cleared alarm in the optical path interruption alarms recorded by the optical cable fault triggering condition acquisition algorithm module, the fault optical cable section, the optical path interruption condition and the fault attention short message are kept consistent, and the fault reason and the processing measure need to be manually input after a monitoring personnel inquires first-line first-aid repair personnel through a telephone. And after the fault recovery short message is automatically edited, the fault recovery short message is also issued through the event management platform.
According to the method, the editing work of the fault attention short message, the fault recovery short message and the like is not required to be executed manually, the automatic generation and sending are carried out, the efficiency is high, errors are not prone to occurring, and the transmission of error information is prevented.
On the basis of the above method embodiment, the method embodiment further includes a process of recording the optical cable fault event, including: after all the fault flows are completed, the whole fault event is recorded for later back check. The optical cable fault event recording is specifically completed by deploying an event recording module in the optical power management system, and the specific content to be recorded comprises: 1) time of occurrence of a fault; 2) a faulty cable segment name; 3) an optical path interruption condition; 4) historical receiving and transmitting optical power values at two ends of each interruption optical path; 5) after each interrupted optical path is repaired, the optical power values are received and transmitted by the two ends; 6) failure recovery time; 7) fault attention short messages; 8) and (5) fault recovery short message.
