Detailed Description
The embodiment of the application provides a fault monitoring method and device and electronic equipment, and solves the problems that the misjudgment rate of interruption faults of a branch optical cable between a primary optical splitter and a secondary optical splitter is high, the reliability of a monitoring result is low, and manpower and material resources are wasted.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. 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 application.
In an embodiment, as shown in fig. 1, a network topology structure diagram of a PON provided in an embodiment of the present application is provided. The PON comprises an OLT installed in a machine room, a network terminal ONU installed in a user site, and an ODN, where the ODN comprises at least one primary optical splitter and at least one secondary optical splitter (in the figure, one primary optical splitter and two secondary optical splitters are taken as an example). The first-level optical splitter is positioned in the optical cross-connecting box, the optical cross-connecting box divides the main optical cable into a plurality of branch optical cables, and the first-level optical splitter broadcasts light beams in the main optical cable to the plurality of branch optical cables through physical channels. The second-level optical splitter is positioned in the optical fiber splitting box, and the optical fiber splitting box divides the branch optical cable under the second-level optical splitter into a plurality of branch optical fibers which are accessed into the ONU. Each group of ONUs belongs to a secondary splitter. The primary optical splitter and the secondary optical splitter in the ODN cannot automatically report network resources of their own information, which may be referred to as dummy resources. Therefore, when a branch optical cable is interrupted between the first-stage optical splitter and the second-stage optical splitter, the first-stage optical splitter and the second-stage optical splitter cannot generate an alarm, and how to monitor the fault of the dummy resource is particularly important.
In a possible implementation manner, in the same PON interface, if the number of ONUs that have a fiber break alarm is not less than a threshold value within a specified time window, an interruption fault occurs in a branch optical cable between a first-stage optical splitter and a second-stage optical splitter, and an alarm is issued.
In another possible implementation manner, when all ONUs have a fiber-breaking alarm within a specified time window under the same secondary optical splitter, a fault that a branch optical cable between the primary optical splitter and the secondary optical splitter breaks down may be derived indirectly, and an alarm is given.
In the two implementation manners, the fault that the Optical Network Unit (ONU) has the branch optical fiber interruption can be directly judged by deriving the fault that the branch optical cable between the primary optical splitter and the secondary optical splitter has the interruption fault, but when the Optical Network Unit (ONU) has the branch optical fiber interruption, the branch optical cable between the primary optical splitter and the secondary optical splitter may not be interrupted. In addition, if some ONUs under the same secondary optical splitter fail to derive a fault that a branch optical cable between the primary optical splitter and the secondary optical splitter is interrupted, an alarm cannot be completed, and a maintenance person cannot check the branch optical cable between the primary optical splitter and the secondary optical splitter in time. Therefore, the single monitoring mode has high misjudgment rate and low reliability of the monitoring result, thereby increasing the workload of maintenance personnel and wasting manpower and material resources.
Therefore, the embodiments of the present application provide a technical solution to solve the above problems, and refer to the following specifically.
For example, as shown in fig. 2, an execution main body of the method may be a server, where the server may be an independent server or a server cluster composed of multiple servers, and the server may be a fault monitoring server that is capable of performing whether an interruption fault occurs in a branch optical cable between a primary optical splitter and a secondary optical splitter of a PON.
The fault monitoring method specifically comprises the following steps:
in S201, the number of first target ONUs with a fiber break alarm is determined.
Specifically, when a branch optical fiber between any ONU and the second-stage optical splitter is broken at the user side, the ONU sends a fiber breakage alarm, and the first target ONUs may all belong to the same second-stage optical splitter or may belong to different second-stage optical splitters. The number of the first target ONUs may be determined by counting the number of the fiber breakage alarms, for example, if the number of the fiber breakage alarms is 7, the number of the first target ONUs in which the optical fiber breakage from the branch of the second-stage optical splitter occurs may be determined to be 7.
In S202, when the number of first target ONUs is not less than the threshold, the second-stage optical splitter to which the first target ONU belongs is determined.
Specifically, the threshold may be set to any value (for example, to 6) according to practical situations, and the embodiment of the present application is not limited herein.
In one possible implementation, S202 may include the following steps:
and determining the network element name in the fiber breakage alarm. And searching a second-level optical splitter corresponding to the first target ONU according to the network element name. For the fiber breakage alarm, information of the ONU and information of the secondary optical splitter to which the ONU belongs are included. The second-level optical splitter and the ONU both have network element names uniquely corresponding to the second-level optical splitter and the first target ONU and the second-level optical splitter corresponding to the first target ONU can be found through the network element names.
In S203, when the first target ONUs all belong to the same second-stage optical splitter, the state of the second target ONU under the same second-stage optical splitter is queried.
Specifically, the state of the ONU may be divided into an online state and an offline state, the state of the ONU is the online state when the branch optical fiber between the ONU and the secondary optical splitter is not interrupted and both the ONU and the secondary optical splitter operate normally, and the state of the ONU is the offline state when the branch optical fiber between the ONU and the secondary optical splitter is interrupted or either one of the ONU and the secondary optical splitter is abnormal.
In one possible implementation manner, S203 may include the following steps:
and associating all the ONUs under the same two-stage optical splitter as a second target ONU. And querying the state of the second target ONU through the target interface.
Specifically, after all ONUs under the secondary optical splitter are determined, the PON interface is called and status information of all ONUs under the PON interface is queried, using the PON interface as a target interface. The second target ONU may include the first target ONU, and the second target ONU may be all ONUs under the same second-level optical splitter, or a predetermined number of ONUs under the same optical splitter. The predetermined number may be 80% of the total number of ONUs in the same optical splitter, and of course, the predetermined number may also be any number according to practical situations, and the embodiment of the present application is not limited herein.
Further, in a possible implementation manner, in order to further invoke all ONUs under the second-stage optical splitter in a later stage, after all ONUs under the same optical splitter are associated, information of all ONUs under the same second-stage optical splitter may also be stored.
Further, in a possible implementation manner, after querying the state of a second target ONU under the same two-stage optical splitter, the state of the second target ONU may also be stored.
In S204, if the states of the second target ONU are all offline states, it is determined that the branch optical cable between the second optical splitter and the first optical splitter is interrupted.
In S205, an optical cable interruption fault alarm is performed.
Specifically, the optical cable interruption fault alarm is only carried out when the number of the first target ONUs for carrying out the fiber breakage alarm is not less than a threshold value and the second target ONUs under the unified splitter are all in an offline state.
According to the technical scheme provided by the embodiment of the application, the first target ONU with the fiber breakage alarm is determined, the second-level optical splitter to which the first target ONU belongs is determined under the condition that the number of the first target ONU is not less than the threshold value, and the state of the second target ONU under the same second-level optical splitter is inquired under the condition that the first target ONU belongs to the same second-level optical splitter. And if the states of the second target ONU are all off-line states, determining that the branch optical cable between the second-stage optical splitter and the first-stage optical splitter is interrupted, and performing optical cable interruption fault alarm. Therefore, only when the number of the first target ONUs for fiber breakage warning is not less than the threshold value and the states of the second target ONUs under the same optical splitter are all in the off-line states, the optical cable interruption fault warning is performed, the branch optical cable interruption condition is judged through multiple monitoring modes provided by the embodiment of the application, the misjudgment rate is low, the reliability of the monitoring result is high, the workload of maintenance personnel is reduced, and manpower and material resources are saved.
For example, as shown in fig. 3, an execution main body of the method may be a server, where the server may be an independent server or a server cluster composed of multiple servers, and the server may be a fault monitoring server that is capable of performing whether an interruption fault occurs in a branch optical cable between a primary optical splitter and a secondary optical splitter of a PON.
The fault monitoring method specifically comprises the following steps:
in S301, the number of first target ONUs with a fiber breakage alarm is determined.
In S302, when the number of first target ONUs is not less than the threshold value, the second-stage optical splitter to which the first target ONU belongs is determined.
In S303, when the first target ONUs all belong to the same second-stage optical splitter, the state of the second target ONU under the same second-stage optical splitter is queried.
In S304, if the states of the second target ONU are all offline states, it is determined that the branch optical cable between the second optical splitter and the first optical splitter is interrupted.
In S305, when the first target ONU belongs to the same second-stage optical splitter, all ONUs in the same second-stage optical splitter are determined.
In S306, it is determined that the branch optical cable between the secondary optical splitter and the primary optical splitter is interrupted when all ONUs in the same secondary optical splitter perform a fiber breakage alarm.
Specifically, when a branch optical fiber between any ONU and a secondary optical splitter (secondary optical splitter) is broken on the subscriber side, the ONU sends a fiber breakage alarm. And counting the alarm quantity of the fiber breakage alarm, and when the alarm quantity of the fiber breakage alarm is the same as the quantity of the ONUs under the same two-stage optical splitter, all the ONUs under the same two-stage optical splitter can be considered to be subjected to the fiber breakage alarm.
In S307, an optical cable interruption fault alarm is performed.
It is to be noted that S301 to S304 and S307 have the same or similar implementations as those of S201 to S205 in the above embodiments, which may be referred to each other, and the embodiments of the present application are not described herein again.

And if the states of the second target ONU are all off-line states, determining that the branch optical cable between the second-stage optical splitter and the first-stage optical splitter is interrupted, and performing optical cable interruption fault alarm. Therefore, only when the number of the first target ONUs for fiber breakage warning is not less than the threshold value and the states of the second target ONUs under the same optical splitter are all in the off-line states, the optical cable interruption fault warning is performed, the branch optical cable interruption condition is judged through multiple monitoring modes provided by the embodiment of the application, the misjudgment rate is low, the reliability of the monitoring result is high, the workload of maintenance personnel is reduced, and manpower and material resources are saved.
In addition, when all the ONUs under the same two-stage optical splitter send fiber breakage alarms, the optical cable interruption fault alarm can be carried out, the misjudgment rate of the optical cable interruption fault is further reduced, the reliability of a monitoring result is improved, the workload of maintenance personnel is further reduced, and manpower and material resources are saved. In addition, after the mode of determining whether the optical cable interruption fault occurs is failed by inquiring the state of the second target ONU, whether the optical cable interruption fault occurs can be determined by a mode of sending a fiber interruption alarm by all the ONUs under the same two-stage optical splitter, and the monitoring reliability is high.
For example, as shown in fig. 4, an execution main body of the method may be a server, where the server may be an independent server or a server cluster composed of a plurality of servers, and the server may be a fault monitoring server capable of performing whether an interruption fault occurs in a branch optical cable between a primary optical splitter and a secondary optical splitter of a PON.

In S404, a cable break alarm is issued without deriving the primary and secondary optical splitters.
In S405, it is determined whether the first target ONUs belong to the same secondary optical splitter, if yes, the process proceeds to S406, and if not, the process proceeds to S407.
