[0045] The embodiments of the present application provide an optical fiber fault positioning method, system, device and medium, which are used to solve the technical problem of small detection range of the existing optical fiber fault positioning method, inability to monitor the slight disturbance of the optical fiber, and low accuracy of the optical fiber fault positioning result.

[0046] In order to make the application purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the following described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0047] Please refer to Figure 1 ,Figure 1 A step flow chart of a fiber fault positioning method provided for an embodiment of the present application.

[0048] The fiber fault positioning method provided by the embodiment of the present application comprises:

[0049] Step 101, in response to the received fiber monitoring data, the fiber monitoring data is used to determine the fault judgment data corresponding to the fiber.

[0050] The fiber monitoring data comprises a plurality of identification signals, and the light signals contained in the identification signals are divided into at least two light signals and emitted through at least two fiber cores contained in the optical fiber.

[0051] In the embodiment of the present application, the fiber monitoring data comprises a plurality of identification signals, and the identification signals comprise at least two light signals and are emitted through at least two fiber cores contained in the optical fiber. When the fiber monitoring data is received, the identification signals corresponding to each fiber interval are compared with the corresponding number threshold in terms of the number of light signals to generate initial interval fault judgment data corresponding to the fiber interval. The light signals corresponding to the initial interval fault judgment data are respectively compared with the corresponding preset signal characteristics to generate target interval fault judgment data corresponding to the fiber interval. The fault judgment data corresponding to all the target interval fault judgment data is used to construct the fault judgment data corresponding to the fiber.

[0052] Step 102, determining whether the fault judgment data meets the preset fault data.

[0053] In the embodiment of the present application, the fault judgment data has three types, which are fiber signal quantity anomaly, signal feature anomaly and signal normality. The preset fault data refers to the data used to verify that the fault judgment data belongs to fiber signal quantity anomaly and / or signal feature anomaly. The fault judgment data is compared with the preset fault data to determine whether there is fiber signal quantity anomaly and / or signal feature anomaly data in the fault judgment data.

[0054] Step 103, if yes, the test signal emitted by the positioning reference position corresponding to the fault judgment data is used to determine the fiber fault data corresponding to the fiber.

[0055] The positioning reference position refers to a position used to divide the fiber into a plurality of intervals and used to emit and receive signals.

[0056] The test signal refers to a plurality of light signals used to verify whether the fiber has disturbance in the transmission process. The light signals contained in the test signal are divided into at least two light signals and emitted through at least two fiber cores contained in the optical fiber.

[0057] In the embodiment of the present application, if the fault judgment data contains abnormal fiber signal quantity and / or signal feature abnormal data, the test signal is sent from the corresponding positioning reference position of the fault judgment data. The reflection signal corresponding to the test signal is compared in signal feature to generate the corresponding fiber abnormal data of the positioning reference position. Based on all the fiber abnormal data, the fiber fault data corresponding to the fiber is determined.

[0058] In step 104, if no, the step of determining the fault judgment data corresponding to the fiber by using the received fiber monitoring data is executed.

[0059] In the embodiment of the present application, if the fault judgment data is normal signal, the step of determining the fault judgment data corresponding to the fiber by using the received fiber monitoring data is executed, and the above steps are repeatedly executed to realize continuous fault monitoring of the fiber.

[0060] In the embodiment of the present application, the fault judgment data corresponding to the fiber is determined by using the received fiber monitoring data. It is judged whether the fault judgment data meets the preset fault data. If yes, the test signal is sent from the corresponding positioning reference position of the fault judgment data to determine the fiber fault data corresponding to the fiber. If no, the step of determining the fault judgment data corresponding to the fiber by using the received fiber monitoring data is executed. The technical problem of small detection range of the existing fiber fault positioning method, which cannot monitor the small disturbance of the fiber, resulting in low accuracy of the fiber fault positioning result, is solved. The fiber fault is preliminarily judged by the fiber monitoring data, and then the test signal is sent from the positioning reference position to further verify the fault, so as to determine the fiber fault position and the fault type.

[0061] Please refer to Figure 2 , Figure 2 The step flow chart of the fiber fault positioning method provided in the second embodiment of the present application is shown.

[0062] Another fiber fault positioning method provided in the second embodiment of the present application comprises:

[0063] In step 201, a plurality of positioning reference positions corresponding to the fiber are respectively and equally spaced at a specified interval between the two ends of the fiber.

[0064] The specified interval refers to the distance range for dividing the fiber into a plurality of fiber intervals.

[0065] In the embodiment of the present application, a plurality of positioning reference positions are arranged on the optical fiber at equal intervals according to a specified interval. The positioning reference positions can be arranged at equal intervals from one end of the optical fiber to the other end of the optical fiber, or the positioning reference positions can be arranged at equal intervals from the other end of the optical fiber to the one end of the optical fiber in reverse. It is worth noting that the distance between adjacent positioning reference positions is set to the specified interval to ensure that the time consumption of the transmission of the identification signal in the subsequent step is the same.

[0066] In step 202, a plurality of optical fiber intervals are constructed by using the two ends of the optical fiber and the positioning reference positions.

[0067] In the embodiment of the present application, the two ends of the optical fiber are respectively constructed into corresponding optical fiber intervals with adjacent positioning reference positions, and each adjacent positioning reference position is constructed into a corresponding optical fiber interval.

[0068] In step 203, corresponding identification signals are respectively sent through the optical fiber intervals.

[0069] In the embodiment of the present application, during the positioning of the optical fiber fault, it is necessary to continuously or intermittently send an identification signal from one end of the optical fiber to the nearest positioning reference position, receive the identification signal at the nearest positioning reference position to the one end of the optical fiber and upload the terminal, send an identification signal from any positioning reference position to the adjacent positioning reference position, receive the identification signal at the positioning reference position and upload the terminal, and send an identification signal from the nearest positioning reference position to the other end of the optical fiber to the other end of the optical fiber, receive the identification signal at the other end of the optical fiber and upload the terminal. After the identification signal of the entire optical fiber is covered, each independent identification signal covers an independent optical fiber interval, and the analysis result of each independent identification signal can also represent the connection state of the optical fiber of an optical fiber interval.

[0070] In step 204, the identification signals of the optical fiber intervals are respectively compared with the corresponding number threshold value to generate initial interval fault judgment data corresponding to the optical fiber intervals.

[0071] The number threshold value refers to the number of optical signals corresponding to each identification signal.

[0072] In the embodiment of the present application, the received identification signals of each optical fiber interval are respectively compared with the corresponding number threshold value to determine whether the number of received optical signals is consistent with the corresponding number threshold value, that is, whether the number of emitted optical signals is consistent with the number of received optical signals, thereby generating initial interval fault judgment data corresponding to each optical fiber interval.

[0073] In step 205, the optical signals corresponding to the initial interval fault judgment data are respectively compared with the corresponding preset signal characteristics to generate target interval fault judgment data corresponding to the optical fiber intervals.

[0074] The preset signal feature refers to the signal feature corresponding to the optical signal before being sent. By comparing the signal feature before being sent and the received signal feature, it is determined whether there is disturbance or failure in the optical fiber section.

[0075] In the embodiment of the present application, the optical signal corresponding to the initial section failure judgment data is compared with the corresponding preset signal feature. If the feature of the received identification signal and the corresponding preset signal feature is complete and the same, it is judged that the received identification signal is correct. In the step of identifying and analyzing the identification signal, if the feature of the received identification signal and the corresponding preset signal feature is incomplete or different, it is judged that the received identification signal is incorrect. It is further determined whether there is a failure in the optical fiber section, and the corresponding failure type is determined, so as to generate the target section failure judgment data corresponding to the optical fiber section. The identification signals sent at different time periods and different positions can be set to be the same as each other, or can be set to be different from each other, but the received identification signal and the preset signal feature must be the same, so as to realize accurate identification of the connection state of the optical fiber in the optical fiber section.

[0076] Step 206, using all the target section failure judgment data, constructing the failure judgment data corresponding to the optical fiber.

[0077] In the embodiment of the present application, all the target section failure judgment data corresponding to the optical fiber section is used as the failure judgment data corresponding to the optical fiber.

[0078] Step 207, judging whether the failure judgment data meets the preset failure data.

[0079] In the embodiment of the present application, the specific implementation process of step 207 is similar to that of step 102, which will not be repeated here.

[0080] Step 208, if yes, determining the optical fiber failure data corresponding to the optical fiber through the test signal sent by the positioning reference position corresponding to the failure judgment data.

[0081] Further, step 208 can include the following sub-steps S11-S13:

[0082] S11, sending the test signal by the positioning reference position corresponding to the failure judgment data respectively.

[0083] S12, comparing the signal features of the test signals to generate the optical fiber abnormal data corresponding to the positioning reference position.

[0084] S13, determining the optical fiber failure data corresponding to the optical fiber according to all the optical fiber abnormal data.

[0085] In the embodiment of the present application, in order to further determine the specific cause of the optical fiber fault, a test signal can be sent to the adjacent positioning reference position or the end of the optical fiber through the positioning reference position corresponding to the fault determination data, the reflection signal of the test signal is received at the positioning reference position where the fault is determined to be the abnormal number of optical fiber signals and / or the abnormal signal characteristics, and the terminal is uploaded, the reflection signal of the test signal is identified and analyzed, that is, the reflection signal corresponding to the test signal is compared in signal characteristics, and the corresponding optical fiber abnormal data of the positioning reference position is generated.

[0086] Further, step S13 can include the following sub-steps S131-S132:

[0087] S131, respectively compare the optical fiber abnormal data with the preset fault control data, determine the fault cause and fault processing scheme corresponding to the optical fiber abnormal data.

[0088] S132, use all the fault causes and fault processing schemes to construct the optical fiber fault data corresponding to the optical fiber.

[0089] In the embodiment of the present application, the preset fault control data includes the fault cause and the corresponding fault processing scheme corresponding to various optical fiber abnormal data. After determining the optical fiber fault position, the fault cause and the corresponding fault processing scheme corresponding to the optical fiber abnormal data are selected from the preset fault control data, and finally the optical fiber fault position determined by the optical fiber interval and the test signal, that is, the positioning reference position where the fault occurs, and all the fault causes and fault processing schemes are used to construct the optical fiber fault data corresponding to the optical fiber.

[0090] Step 209, if not, then jump to execute the step of determining the fault determination data corresponding to the optical fiber by using the received optical fiber monitoring data in response to the received optical fiber monitoring data.

[0091] In the embodiment of the present application, the specific implementation process of step 209 is similar to that of step 104, which will not be repeated here.

[0092] In the embodiment of the present application, a plurality of positioning reference positions corresponding to the optical fiber are respectively and equidistantly arranged at a specified interval between the two ends of the optical fiber. The two ends of the optical fiber and the positioning reference positions are used to construct a plurality of optical fiber intervals. Then the corresponding identification signals are respectively sent out by the optical fiber intervals. The identification signals corresponding to each optical fiber interval are compared with the corresponding number threshold to generate initial interval fault judgment data corresponding to the optical fiber interval. The optical signals corresponding to the initial interval fault judgment data are respectively compared with the corresponding preset signal characteristics to generate target interval fault judgment data corresponding to the optical fiber interval. The target interval fault judgment data is used to construct fault judgment data corresponding to the optical fiber. It is judged whether the fault judgment data meets the preset fault data. If yes, the test signal emitted by the positioning reference position corresponding to the fault judgment data is used to determine the optical fiber fault data corresponding to the optical fiber. If no, the step of determining the fault judgment data corresponding to the optical fiber by using the optical fiber monitoring data received in response is executed. After the identification signal of the whole optical fiber is covered, each independent identification signal covers the optical fiber of an independent interval, and the analysis result of each independent identification signal can also represent the connection state of the optical fiber of an independent interval, which is beneficial to intuitively judging the position of the optical fiber fault by monitoring data. And the test signal is further used to determine the fault cause and fault processing scheme corresponding to the optical fiber fault.
