Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining an optical cable interruption.
Background
In actual operation of a Passive Optical Network (PON) Optical cable, interruption is often caused by factors such as artificial damage or natural environment influence, and at this time, a fault point needs to be located and maintained in time. However, the location of PON faults by tip maintenance personnel is difficult. Moreover, the work responsibilities of the terminal maintenance personnel of the operator and the optical cable transmission first-aid repair personnel are distinguished. When a fault occurs, a terminal maintenance worker obtains the trunk optical power of the first-stage optical splitter and the second-stage optical splitter by using an optical power meter, preliminarily judges fault points step by step according to experience, and forwards a fault work order to optical cable transmission first-aid repair workers after the fault of the trunk optical cable is positioned. The transmission first-aid repair personnel then use an optical time-domain reflectometer (OTDR) to judge the fault interruption node, and simultaneously obtain the affected service range according to the optical cable ledger, and notify the customer service and service manager. The management and maintenance mode is passive, which causes the long time of the fault solving process, leads to poor perception of the final user and reduces the trust degree of the client on the operation commodity plate. Therefore, in the PON, when the optical cable is abnormal, how to change from the passive maintenance mode to the active maintenance mode becomes a problem to be solved urgently.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present invention, the meaning of "a plurality" means two or more unless otherwise specified.
The optical cable interruption determination method provided in the embodiment of the present invention may be applied to a PON-related alarm system, and as shown in fig. 1, the system may include: a PON port disposed on a Network device (in fig. 1, the Network device is an Optical Line Terminal (OLT) as an example), a Network side interface disposed on the Network device, an Optical cable cross-connect box, a multi-stage Optical splitter, such as the first-stage Optical splitter, the second-stage Optical splitter (of course, the multi-stage Optical splitter is not limited to two stages, and may also include a third-stage Optical splitter, or a higher-stage Optical splitter) shown in fig. 1, and an Optical Network Terminal (ONT).
The optical cable cross-connecting cabinet, also called as optical cross-connecting cabinet or street cabinet, optical cable cross-connecting cabinet, etc. is generally placed on the interface of main optical cable and service distribution optical cable, and is used for branching optical cable, matching, melting fiber, storing, regulating and protecting, etc. In the system shown in fig. 1, all optical cables included between the PON port and the cable distribution box 3 are referred to as trunk cables. All of the cables contained between the cable distribution cabinet 3 and the OLT are referred to as drop distribution cables. The user distribution cable comprises a primary optical splitter access cable, a secondary optical splitter access cable, an ONT access cable and the like.
It is understood that the PON port subordinate may be connected to one or more optical cable cross-connect boxes, one optical cable cross-connect box may be connected to one or more primary optical splitters, one primary optical splitter may be connected to one or more secondary optical splitters, and one secondary optical splitter may be connected to one or more ONTs. Only a partial number of the individual functional units are shown in fig. 1 by way of example.
The system shown in fig. 1 further includes an alarm platform, which is used to obtain alarm information and a networking structure of the PON and has a calculation and display function.
It should be noted that fig. 1 is only an exemplary architecture diagram, and besides the functional units shown in fig. 1, the network architecture may also include other functional units, which is not limited in this embodiment of the present invention.
The method for judging the interruption of the optical cable provided by the embodiment of the invention is applied to the system shown in figure 1. As shown in fig. 2, the method may include S201-S204:
s201, the alarm platform acquires alarm information of the PON port.
Specifically, PON port alarm information based on the OLT is collected in real time through various types of network management detection devices, and then the alarm information is transmitted to a centralized alarm platform similar to an Enterprise Service Bus (ESB) through an Application Programming Interface (API) Interface on the network management detection device. For example, when the ONT loses power and the OLT receives a power down message from the ONT, alarm information may be generated, where the alarm information is used to indicate that the ONT loses power.
In the embodiment of the invention, the alarm platform can automatically cluster alarm information through an Artificial Intelligence (AI) function. A fault is a cause of generating alarms, and a fault may generate a large amount of alarms from active network components (for example, as shown in fig. 1, when a secondary optical splitter is disconnected from an optical cable, alarm information is generated by components connected to the optical cable and components in a subordinate line of the optical cable), and some of the alarms are redundant, which makes fault location determination and processing complicated. Therefore, the alarm information is clustered through the AI, the alarm information of different categories is divided into different clusters, and the alarm information in the same cluster is similar to the alarm information in the same cluster, and is the alarm information corresponding to the ONT fault compared with the alarm information in the same cluster, or the alarm information in the same cluster is the alarm information corresponding to the equipment power failure. Therefore, the root alarm for generating the fault is obtained, some redundant alarms are eliminated, and the accuracy of fault positioning is improved.
S202, the alarm platform acquires networking structure information of the PON.
Specifically, image information such as a PON optical cable completion drawing is identified by using an AI image identification function, and corresponding networking structure information is acquired based on the image information such as the completion drawing.
In a possible implementation manner, the networking information may include the number, coordinates, connection structure of each functional unit (such as a first-level optical splitter) shown in fig. 1, and line resource length information between each functional units. It is understood that the networking architecture should also include other information, and the invention is not limited in this regard.
S203, the alarm platform acquires the optical cable interruption position according to the alarm information and the networking structure information.
In one possible implementation, as shown in fig. 1, the PON trunk cable interruption position determination. Since the main optical cable is formed by connecting one or more levels of optical cable cross-connecting boxes in series (for example, the optical cable cross-connecting box 1 located at a first level, the optical cable cross-connecting box 2 located at a second level, and the optical cable cross-connecting box 3 located at a third level shown in fig. 1, where the first level is the highest level), in the prior art, when an interruption alarm of the main optical cable occurs, it cannot be directly determined which level of optical cable cross-connecting box fails to generate the alarm information.
In order to solve the above technical problem, in the embodiment of the present invention, PON port fiber breakage warning information and ESB warning information based on the OLT may be acquired, and are simultaneously associated with a fiber core account carried by a pipeline resource system, so that it may be determined which level of the optical cable cross-connecting cabinet is interrupted. As shown in fig. 3, which is a schematic view of a cutting surface of a certain optical cable, it can be seen that an optical cable is composed of a plurality of optical fibers, and the plurality of optical fibers carry one or more services. The fiber breakage warning information refers to warning information generated when one or more optical fibers included in a certain optical cable are broken. The ESB alarm information may include various alarm clusters of a base station, a transmission Synchronous Digital Hierarchy (SDH), an IP Access Network (IPRAN), a large client Access, and other devices. The fiber core standing book refers to the service type carried by each optical fiber in the optical cable. For example, in a certain optical cable, the fiber core 1 is used for carrying SDH traffic, the fiber cores 2 and 3 are used for carrying IPRAN traffic, and the fiber cores 4 and 5 are used for accessing a certain base station, that is, the optical cable carries three types of traffic.
In one possible scenario, in a system such as that shown in FIG. 1. In a period of time, the alarm platform collects the alarm information of three services, namely an SDH service, an IPRAN service and a base station access service.
The fiber core standing book obtains that the access optical cable of the optical cable cross connecting cabinet 1, the access optical cable of the optical cable cross connecting cabinet 2 and the access optical cable of the optical cable cross connecting cabinet 3 all bear the three services.
In one scenario, in 3 optical cable cross-connecting boxes shown in fig. 1, an access optical cable of the optical cable cross-connecting box 1 bears and only bears the three services, that is, within a period of time, an alarm platform acquires alarm information of the 3 services from the optical cable cross-connecting box 1, and learns the 3 services, that is, all the services borne by the optical cable cross-connecting box 1, according to a fiber core account, and further, the alarm platform can learn that all the services borne on the access optical cable of the optical cable cross-connecting box 1 all generate alarm information. At this time, referring to fig. 1, in the networking structure, the optical cable cross-connecting cabinet 1 is the optical cable cross-connecting cabinet at the highest level, and it is determined that the access optical cable corresponding to the optical cable cross-connecting cabinet 1 is broken.
In another scenario, when an access cable is disconnected, alarm information may be generated by both the components connected to the cable and the components in the drop line of the cable. Namely, it is determined that the access optical cable corresponding to the optical cable cross-connecting cabinet at the highest level among the optical cable cross-connecting cabinets corresponding to the access optical cables in which all services borne within the preset time period generate the alarm information is interrupted. Illustratively, the alarm platform collects alarm information of the above 3 services from the optical cable cross-connecting cabinet 2 and the optical cable cross-connecting cabinet 3, and as can be known from the fiber core ledger, the access optical cable of the optical cable cross-connecting cabinet 2 only carries the three services, that is, within a period of time, all services carried on the access optical cable of the optical cable cross-connecting cabinet 2 generate alarm information. The access optical cable of the optical cable cross-connecting cabinet 3 only carries the three services, that is, all the services carried on the access optical cable of the optical cable cross-connecting cabinet 3 generate alarm information within a period of time. And, referring to the networking architecture shown in fig. 1, the cable cross-connecting cabinet 2 is higher in level than the cable cross-connecting cabinet 3. In this way, it is inferred that in the networking structure, the access optical cable of the optical cable cross-connecting cabinet 2 of the higher hierarchy is interrupted, and thus, the optical cable cross-connecting cabinet 2 generates the above alarm information, and may cause the optical cable cross-connecting cabinet 3 of the next hierarchy to generate the above alarm information.
In another possible scenario, the alarm platform may collect alarm information of the 3 services from the cable cross-connecting cabinet 1, the cable cross-connecting cabinet 2, and the cable cross-connecting cabinet 3, respectively. And, the fiber core ledger can know that all the services carried on the access optical cable of the optical cable cross connecting cabinet 2 generate alarm information. All services carried on the access optical cable of the optical cable cross connecting cabinet 3 generate alarm information, and the optical cable cross connecting cabinet 1 carries other services besides the 3 services. In this case, the alarm platform detects other services carried by the access optical cable of the optical cable cross-connecting cabinet 1 to determine whether the access optical cable of the optical cable cross-connecting cabinet 1 is interrupted. If it is detected that the access optical cable of the optical cable cross-connecting cabinet 1 carries the presence of the online service, that is, an access client (the access client is not the access client of the optical cable cross-connecting cabinet 2) is online, it indicates that the access optical cable of the optical cable cross-connecting cabinet 1 is not interrupted. In connection with the discussion of the previous paragraph, it can be inferred that the cable distribution cabinet 2 at a higher level is broken. If it is detected that no online service exists in the access cable bearer of the cable cross-connecting cabinet 1, that is, no access client (the part of the access client is not the access client of the cable cross-connecting cabinet 2) is online, it indicates that the access cable of the cable cross-connecting cabinet 1 is interrupted.
Referring to the position of the secondary optical splitter access optical cable in fig. 1, it can be known that the access optical cable is an optical cable of the input portion of each functional unit. Based on this, the determination method of the optical cable interruption at other positions on the main optical cable may refer to the above description, and the embodiment of the present invention is not described again.
In another possible implementation manner, in the system shown in fig. 1, according to the PON networking structure, the determination manner of the drop location of the in-house distribution cable is as follows:
optionally, if an ONT alarms within a predetermined time period and other ONTs connected to the same secondary splitter with the ONT are in a normal working state, it indicates that the secondary splitter is in a normal working state, and in this case, the alarm platform determines that the ONT corresponding to the ONT accesses the optical cable to be interrupted. The ONT access optical cable is an optical cable used for connecting the secondary optical splitter and the ONT.
Optionally, if a warning occurs on a first portion of ONTs within a predetermined time period and the first portion of ONTs are all ONTs operating under the same secondary optical splitter, in this case, the warning platform determines that the secondary optical splitting access optical cable corresponding to the secondary optical splitter is interrupted.
Optionally, if a second part of the ONTs alarms within a predetermined time period and the second part of the ONTs is all the ONTs working under the same primary optical splitter, in this case, the alarm platform determines that the primary optical splitting access cable corresponding to the primary optical splitter is interrupted.
S204, the alarm platform acquires the interval range of optical cable interruption according to the optical cable interruption position and the networking structure information of the PON.
Specifically, in the system shown in fig. 1, length information of each line from the PON port to the optical cable cross-connecting box, from the optical cable cross-connecting box to the first-stage optical splitter, and from the first-stage optical splitter to the second-stage optical splitter may be obtained according to networking structure information. For example, it is assumed that the line length between the PON port and the optical cable cross-connecting cabinet 1 is 500 meters, the line length between the optical cable cross-connecting cabinet 1 and the optical cable cross-connecting cabinet 2 is 600 meters, the line length between the optical cable cross-connecting cabinet 2 and the optical cable cross-connecting cabinet 3 is 800 meters, the line length between the primary optical splitter and the secondary optical splitter is 600 meters, and the length of the rubber-insulated optical cable connected to the customer is 100 meters. The total access length of the client is 2600 meters. As a possible implementation manner, the access total lengths of all the clients are saved in the network management device, and AI cluster calculation is performed according to the optical cable interruption position and the client access total length, so that the interval range of the optical cable interruption can be judged. For example, when it is determined that the primary optical splitter access optical cable corresponding to the primary optical splitter accessed by the customer is interrupted, the fault point (i.e., the primary optical splitter access optical cable) can be known to be located at a position 700 (600 + 100) meters away from the customer by combining with the networking structure information of the PON, so that the first-aid repair personnel can directly know the coordinate of the fault point on the warning platform, and can quickly reach the fault point for repair.
The optical cable interruption judging method provided by the embodiment of the invention acquires alarm information of a PON port and networking structure information of a PON; acquiring an optical cable interruption position according to the alarm information and the networking structure information; and acquiring the interval range of optical cable interruption according to the optical cable interruption position and the networking structure information of the PON. Compared with the passive maintenance mode in the prior art, the passive maintenance mode is characterized in that the PON fault position is judged manually. According to the optical cable interruption judgment method provided by the invention, the alarm information of the PON port and the networking structure information of the PON are utilized, the range of the optical cable interruption interval can be automatically identified, passive maintenance is changed into active maintenance, and the fault maintenance efficiency can be improved.
