Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a method for identifying a cable fault in an electrical power communication network, including:
s1, acquiring an alarm information group in the power communication network, and if it is determined that there is a first type of alarm information in the alarm information group, determining whether there is a second type of alarm information in the alarm information group, where the first type of alarm information is light loss alarm information respectively sent by communication devices at two ends of a light path in the power communication network, and the second type of alarm information is light loss alarm information respectively sent by communication devices at two ends of another light path in the power communication network;
and S2, if the optical path corresponding to the first type of alarm information and the optical path corresponding to the second type of alarm information are judged to be in the same optical cable, determining that the optical cable in which the optical path corresponding to the first type of alarm information is positioned has a fault.
Specifically, the optical cable fault identification depends on the inclusion relationship between the optical cable and the optical cable fiber core, the association relationship between the optical cable fiber core and the communication equipment, and the light loss alarm information of the communication equipment at two ends of the optical cable fiber core.
The optical cable fault identification method provided by the invention is mainly directed to an electric power communication network, wherein a plurality of optical cables exist in the electric power communication network, and each optical cable comprises a plurality of optical fibers. It should be noted that the fiber core of the optical cable in the present invention refers to an optical fiber, for example, a 24-core optical cable refers to an optical cable having 24 optical fibers, and every two optical fibers in the 24 optical fibers are used in combination to form an optical path, where one optical fiber is used for receiving information and the other optical fiber is used for transmitting information.
The alarm information group in the invention refers to all alarm information possibly existing in the power communication network, the alarm information is usually sent by communication equipment connected with two ends of a fiber core of an optical cable, the alarm information can comprise various types, and the invention mainly introduces the light-missing alarm information. Firstly, judging whether first-class alarm information exists in an alarm information group according to optical cable resource data, namely whether light loss alarm information exists at two ends of one optical path simultaneously in an electric power communication network, judging whether light loss alarm information exists at two ends of the other optical path simultaneously after determining that the light loss alarm information exists at two ends of the one optical path simultaneously, and determining that the optical cable breaks down if the two optical paths are in a common cable. If the first type of alarm information does not exist in the alarm information group, whether the optical cable has a fault or not cannot be determined, and the fault does not occur by default.
In the invention, whether two optical paths exist or not is judged, light loss alarm information exists at two ends of the two optical paths at the same time, and the two optical paths belong to the same optical cable, so that the optical cable is determined to have a fault. By the method, the influence of human factors on the judgment of the optical cable fault can be avoided, the time for determining the optical cable fault is greatly shortened, and the duration time of the optical cable fault is further shortened. Meanwhile, the invention comprehensively considers the relation among the fiber core, the optical path and the optical cable of the optical cable to identify the fault optical cable, and the identification method has higher automation degree and higher accuracy.
On the basis of the above embodiment, the method for determining the light loss alarm information from the alarm information group in the present invention specifically comprises: analyzing and summarizing alarm names sent by communication equipment provided by various manufacturers, identifying alarm names reflecting light loss alarm information of ports of the communication equipment as light loss alarm names, defining the light loss alarm information according to the light loss alarm names, and sending the light loss alarm names sent by the communication equipment provided by various manufacturers as shown in the following table 1.
Table 1 name of light loss alarm corresponding to communication device provided by each manufacturer
In the invention, the light loss alarm names of each technical system and each manufacturer of the power communication network are summarized, and the light loss condition of each port of the optical cable can be accurately reflected by the listed light loss alarm names.
On the basis of the above embodiment, the time for analyzing the light loss alarm information in the present invention is calculated according to the acquisition time of the light loss alarm information of the network management system, and the analysis time window of the light loss alarm information is tentatively set to 5 minutes, that is, after receiving the light loss alarm information, other light loss alarm information within 5 minutes is inquired before the time of receiving the light loss alarm information for comparative analysis.

On the basis of the above embodiment, the method provided by the present invention further includes: if the optical path corresponding to the first type of alarm information and the optical path corresponding to the second type of alarm information are judged to be not in the same optical cable, whether matched communication equipment exists at the two ends of the fiber cores of other optical cables except the optical path corresponding to the first type of alarm information in the optical cable corresponding to the optical path corresponding to the first type of alarm information or not is judged, and if the matched communication equipment does not exist at the same time, the optical cable where the optical path corresponding to the first type of alarm information exists is judged to have a fault.
Specifically, if a first type of alarm information and a second type of alarm information exist in an alarm information group, that is, it is stated that at least two optical paths with light loss alarm information at both ends exist in a circuit communication network, when the optical paths corresponding to the first type of alarm information and the second type of alarm information are not located in the same optical cable, it is impossible to determine whether the optical cable is faulty through the alarm information sent by the communication devices connected at both ends of the optical cable core, at this time, it is necessary to determine whether the optical cable with the optical path corresponding to the first type of alarm information exists in the optical cable with other optical cable cores of the communication devices at both ends, which are matched with each other, and if the optical cable cores of the communication devices at other both ends exist at the same time, it is stated that the optical cable cores of the other communication devices at both ends, which are matched with each other, have the ability of sending light loss alarm information, but have not been sent, at this time, it cannot be determined whether the optical cable where the optical path corresponding to the first type of alarm information is located has a fault, and no fault is caused by default.
When the optical cable where the optical path corresponding to the first type of alarm information is located does not have other optical cable fiber cores, two ends of which have communication devices that are matched with each other, at the same time, that is, neither or only one end of the optical cable fiber cores in the optical cable where the optical path corresponding to the first type of alarm information is located has communication devices, it is described that in the optical cable where the optical path corresponding to the first type of alarm information is located, the other optical cable fiber cores are idle or bear special fiber core services, the optical cable does not have the capability of sending light loss alarm information, but both ends of one optical path in the optical cable have light loss alarm information, so that the optical cable is defaulted to have a fault at this time. It should be noted that the communication device in the present invention is a communication device having an alarmable function.
In the embodiment, the bearing condition of the optical cable is analyzed, the fault of the optical cable is judged in an auxiliary mode by analyzing the application condition of the fiber core of the optical cable, a special scene is considered, and the fault judgment result is more accurate.
On the basis of the above embodiment, after determining that the optical cable has a fault, the optical cable having the fault and the optical cable where the optical cable is located are marked.
On the basis of the above embodiment, after determining that the optical cable has a fault, the method further includes:
and determining the risk levels of the faults of the optical cable according to preset judgment conditions, wherein the risk levels comprise a first level, a second level, a third level and a fourth level.
Specifically, the risk level of the fault of the optical cable is determined, namely the risk judgment is carried out on the fault of the optical cable, the process is carried out after the fault of the optical cable is determined, the risk level of the fault of the current optical cable is judged so as to reasonably arrange the repair work of the fault of the optical cable, the fault with higher risk level requires quick emergency access, namely the optical cable with the first level fault needs to be maintained for the first time, and the subsequent maintenance sequence sequentially comprises the optical cable with the second level fault, the optical cable with the third level fault and the optical cable with the fourth level fault.
In the embodiment, the risk level of the fault is determined, a large amount of resource bearing data is read in the determination process for comprehensive analysis, and the reliability of the analysis result is high.
The setting of the preset decision condition is determined based on both the traffic carried by the optical cable and the duration of the fault occurring in the optical cable. The risk level classification of the faults employed by the present invention is shown in table 2.
