Description

Technical Field

[0001] This invention relates to the field of optical cable monitoring technology, and in particular to an optical cable monitoring method, device, system and storage medium. Background Technology

[0002] Optical fiber is widely used in the field of communications and has advantages such as high speed, large capacity and low loss. However, with the increasing number of optical cables laid between cities, the daily operation and maintenance of optical cables has become a heavy task.

[0003] In the field of optical transmission line operation and maintenance, optical time-domain reflectometry (OTDR) is used to determine the fiber length of the fiber optic endpoint corresponding to the fault point in the equipment room. Distributed vibration sensing (DVS) devices use distributed optical fiber sensing technology to accurately locate vibration points. Due to different application scenarios, when there is both fiber core monitoring and fiber vibration monitoring, users often use two devices for fiber monitoring, or only a single device. Existing fiber monitoring systems have limited functionality and poor compatibility. Summary of the Invention

[0004] This invention provides a method, device, system, and storage medium for monitoring optical cables, which is compatible with OTDR mode and vibration monitoring mode, realizes automatic switching of working mode of optical cable monitoring, and improves the applicability of optical cable monitoring system.

[0005] The first aspect of this invention provides a method for monitoring optical cables. The method is applied to an optical cable monitoring system connected to an optical cable monitoring device. The optical cable monitoring device includes at least one port to be tested, each port being connected to a fiber core of an optical cable to be tested. The optical cable monitoring device is equipped with an optical switch for switching the operating modes of the device, including an OTDR mode and a vibration monitoring mode. The device includes an OTDR unit for executing the OTDR mode and a distributed optical fiber vibration sensing unit for executing the vibration monitoring mode. The method includes: configuring tasks for each port to be tested in the optical cable monitoring device to obtain a task configuration list; and configuring tasks according to the specified parameters. The configuration list controls the optical cable monitoring device to switch modes and execute target monitoring tasks for the corresponding ports to be tested, obtaining optical cable monitoring data for each port to be tested. When a vibration alarm trigger signal is generated based on the optical cable monitoring data of any port to be tested, the port to be tested is identified as the first target port to be tested, and the optical cable monitoring device is controlled to pause the execution of the task configuration list. The optical cable monitoring device is then controlled to switch to OTDR mode to perform fiber core monitoring on the first target port to be tested, obtaining the first fiber core monitoring data corresponding to the first target port to be tested. If a first fault point is determined based on the first fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are continued to be executed.

[0006] A second aspect of the present invention provides an optical cable monitoring device, which is applied to an optical cable monitoring system. The optical cable monitoring system is connected to an optical cable monitoring equipment. The optical cable monitoring equipment includes at least one port to be tested, each port to be tested being connected to a fiber core of an optical cable to be tested. The optical cable monitoring equipment is equipped with an optical switch for switching the operating modes of the optical cable monitoring equipment. The operating modes include an OTDR mode and a vibration monitoring mode. The optical cable monitoring equipment is equipped with an OTDR unit for executing the OTDR mode and a distributed optical fiber vibration sensing unit for executing the vibration monitoring mode. The optical cable monitoring device includes: a configuration module for configuring tasks for each port to be tested of the optical cable monitoring equipment to obtain a task configuration list; and an execution module for executing tasks according to the task configuration list. The system controls the optical cable monitoring device to switch modes and execute target monitoring tasks for the corresponding ports to be tested, obtaining optical cable monitoring data for each port to be tested; a vibration alarm module is used to determine the port to be tested as the first target port to be tested when a vibration alarm trigger signal is generated based on the optical cable monitoring data of any port to be tested, and controls the optical cable monitoring device to pause the execution of the task configuration list; a switching module is used to control the optical cable monitoring device to switch to OTDR mode, perform fiber core monitoring on the first target port to be tested, and obtain the first fiber core monitoring data corresponding to the first target port to be tested; a processing module is used to generate alarm information and continue to execute the remaining target monitoring tasks in the task configuration list if a first fault point is determined based on the first fiber core monitoring data.

[0007] A third aspect of the present invention provides an optical cable monitoring system, comprising: a memory and at least one processor, wherein the memory stores instructions; the at least one processor invokes the instructions in the memory to cause the optical cable monitoring device to perform the optical cable monitoring method described above.

[0008] A fourth aspect of the present invention provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the above-described optical cable monitoring method.

[0009] The technical solution provided by this invention enables multi-port polling detection through task configuration. The optical cable monitoring device is controlled to switch modes according to the task configuration list, allowing compatibility with OTDR mode and vibration monitoring mode, and automatic switching of the optical cable monitoring working mode. Upon the occurrence of a vibration alarm trigger signal, fiber core monitoring is immediately performed on the port, generating alarm information and providing early warning of faults. This improves the mode switching speed for fault identification, enhances the flexibility of task configuration in the optical cable monitoring system, and achieves automatic multi-port polling monitoring. Automatic task adjustment is performed upon the occurrence of an alarm signal, improving the fault location efficiency of the optical cable monitoring system. Attached Figure Description

[0016] This invention provides a method, device, system, and storage medium for monitoring optical cables, which addresses the technical problems of limited functionality and poor compatibility in optical cable monitoring systems.

[0017] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0018] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the optical cable monitoring method in this invention includes:

[0019] 101. Configure tasks for each port to be tested on the optical cable monitoring equipment to obtain a task configuration list.

[0020] It is understood that the executing entity of this invention can be an optical cable monitoring device, an optical cable monitoring system, an optical cable monitoring terminal, or a server; no specific limitation is made here. This embodiment of the invention will be described using an optical cable monitoring system as an example.

[0021] The optical cable monitoring system is connected to the optical cable monitoring equipment. The optical cable monitoring equipment includes one or more first ports (or first channels), each first port is connected to the corresponding optical cable to be tested. The optical cable monitoring equipment is equipped with an optical switch, which is used to switch the working mode of the optical cable monitoring equipment. The working modes include OTDR mode and vibration monitoring mode. The optical cable monitoring equipment is equipped with an OTDR unit that performs OTDR mode and a distributed optical fiber vibration sensing unit that performs vibration monitoring mode.

[0022] The optical cable monitoring equipment has two monitoring functions to meet the two application scenarios of optical cable core monitoring and optical cable vibration monitoring. The optical cable monitoring equipment can perform optical cable core monitoring tasks and / or optical cable vibration monitoring tasks by switching working modes.

[0023] In this embodiment, the fiber core monitoring is based on the OTDR technology principle to measure the Rayleigh scattering or Fresnel reflection signal of the optical fiber back, and uses the time and attenuation characteristics of light propagation in the optical fiber to detect faults, so as to determine whether there are faults such as cable breakage, and determine the length of the optical fiber corresponding to the fault location.

[0024] In this embodiment, cable vibration monitoring is based on the DVS technology principle. It measures the vibration characteristic images of the optical cable under test caused by construction near the optical cable, and performs image analysis on the vibration characteristic images to identify vibration events, so as to realize early warning and avoid accidents.

[0025] The optical cable monitoring system configures tasks for each port to be tested. Each port to be tested can have one or two target test tasks. That is, it can perform optical cable core monitoring task only on the port to be tested, or only perform optical cable vibration monitoring task, or perform optical cable core monitoring task and optical cable vibration monitoring task sequentially on the port to be tested.

[0026] Understandably, there are no specific restrictions on the order in which the ports to be tested are ordered. It is possible to prioritize testing the ports corresponding to the faulty optical cables in the historical faulty optical cable data, or to prioritize testing the ports corresponding to the optical cables to be tested whose laying path passes through the construction site.

[0027] This embodiment does not impose specific restrictions on the execution order of the optical fiber core monitoring task and the optical fiber vibration monitoring task. The optical fiber vibration monitoring task can be executed first for each port to be tested, and then the optical fiber core monitoring task can be executed, or the optical fiber vibration monitoring task can be polled for all ports to be tested, and then the optical fiber core monitoring task can be executed for each port to be tested.

[0028] 102. Control the optical cable monitoring equipment to switch modes according to the task configuration list, and execute the target monitoring task for the corresponding port to be tested, so as to obtain the optical cable monitoring data corresponding to each port to be tested.

[0029] In this embodiment, the task configuration list includes multiple target monitoring tasks. According to the test start time and test order of each target monitoring task in the task configuration list, the optical cable monitoring device is controlled to poll and monitor each port to be tested according to the corresponding target monitoring task, so as to obtain the optical cable monitoring data corresponding to each port to be tested.

[0030] Each target monitoring task includes corresponding task information, such as task type, port number (or channel number), test sequence, test pulse width, test start time, test duration, test range, test wavelength, test cycle, and fiber optic alarm length.

[0031] In this embodiment, the task types include fiber core monitoring tasks and vibration monitoring tasks. When performing a fiber core monitoring task, the optical cable monitoring device needs to enter OTDR mode, and the obtained optical cable monitoring data is fiber core monitoring data. When performing a fiber core monitoring task, the optical cable monitoring device needs to enter vibration monitoring mode, and the obtained optical cable monitoring data is vibration monitoring data.

[0032] In this embodiment, the port number is the identification code corresponding to the port to be tested, and each port to be tested corresponds to one end of the optical cable to be tested. The port number is used to identify the corresponding optical cable to be tested when an alarm message is generated. The test sequence is used to identify the execution order of the target monitoring task, and the test pulse width is the pulse width required to execute the target monitoring task. The test range is used to indicate the length range of the optical cable to be tested corresponding to the target monitoring task. The test wavelength is used to indicate the wavelength of the laser light source corresponding to the target monitoring task. The test cycle is used to indicate the cycle of the target monitoring task. The optical cable alarm length is used to indicate the length of the optical cable to be executed when an alarm trigger signal is generated.

[0033] In this embodiment, the test start time indicates the moment when the set target monitoring task begins execution; the test duration is the execution time corresponding to the target monitoring task. The test duration for each vibration monitoring task can be manually adjusted, executed according to the default value, or set to the same or different test durations for each port to be tested based on other factors. For example, it can be set according to the number of ports to be tested to be polled, the energy consumption of the optical cable monitoring equipment, the operating resources for executing the vibration monitoring task, etc., or according to the frequency characteristics of vibration events corresponding to historical optical cable vibration data, such as setting the test duration for each vibration monitoring task to 300 seconds, or other values. The test duration for each fiber core monitoring task is automatically calculated according to the specific equipment conditions, such as setting the test duration for each fiber core monitoring task to 2 seconds, or other values.

[0034] 103. When a vibration alarm trigger signal is generated based on the optical cable monitoring data of any one of the ports to be tested, the port to be tested is identified as the first target port to be tested, and the optical cable monitoring equipment is controlled to suspend the execution of the task configuration list.

[0035] The optical cable monitoring system uses intelligent image analysis technology to identify vibration events from the vibration monitoring data of the currently polled port to be tested. When a target vibration event is identified and the vibration intensity of the target vibration event is greater than the preset vibration threshold, a vibration alarm trigger signal is generated for the first target port to be tested. This controls the optical cable monitoring equipment to suspend the execution of the task configuration list, so as to achieve early warning and mark the optical cables to be tested that may have faults such as cable breakage.

[0036] It should be further explained that although the optical cable monitoring data also includes fiber core monitoring data, before the alarm trigger signal is generated directly through the analysis of fiber core monitoring data, the optical power alarm trigger signal will be triggered first because the optical power equipment is tested in real time. Therefore, this embodiment only describes the triggering scenario of the vibration alarm trigger signal. The triggering scenario of the optical power alarm trigger signal is detailed in the next embodiment.

[0037] 104. Control the optical cable monitoring equipment to switch to OTDR mode, perform fiber core monitoring on the first target port to be tested, and obtain the first fiber core monitoring data corresponding to the first target port to be tested.

[0038] The optical cable monitoring system creates a fiber core monitoring task corresponding to the first port to be tested of the target and inserts it into the first test order of the current task configuration list. It controls the optical cable monitoring equipment to switch to OTDR mode, performs fiber core monitoring on the first port to be tested of the target, and obtains the first fiber core monitoring data corresponding to the first port to be tested of the target, so as to confirm in real time whether the current target vibration event has caused cable breakage or other faults.

[0039] 105. If a first fault point is determined based on the first fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed.

[0040] The optical cable monitoring system constructs a periodic curve based on the monitoring data of the first fiber core and retrieves the corresponding reference curve of the optical cable under test. The reference curve and the periodic curve are compared to obtain a list of periodic events. If there is a fault event in the list of periodic events, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed to realize polling monitoring and fault alarm.

[0041] The periodic event list includes one or more periodic events. Each periodic event includes information such as the corresponding event name, event location, loss value at the location, and reflectivity. The periodic event list may include one or more events such as absorption events due to connector or end face absorption, bending events due to fiber bending loss, fiber core breakage events caused by excessive fiber bending or external force, scattering events caused by fiber impurities, and reflection events caused by changes in medium density at fiber connectors, ends, and boundary points.

[0042] The reference curve is either the curve corresponding to the fiber core monitoring data collected under normal conditions of the optical cable under test, or the curve corresponding to the historical fiber core monitoring data of the optical cable under test. The reference curve marks the corresponding reference events, that is, the reference curve corresponds to the reference event list, and the reference event is one or more events corresponding to the reference curve.

[0043] Fault events are used to indicate events in the periodic event list where the event parameters have reached the fault judgment criteria. For example, the event name is fiber core breakage event, or the loss value has exceeded the preset value. The occurrence of a fault event indicates that the optical cable under test corresponding to the port under test needs to be repaired or replaced. Therefore, alarm information corresponding to the fault event needs to be generated.

[0044] The alarm information may include the fault events of the optical cable under test. The fault events include the event name, event location, loss value at the location, reflectivity and other information. The alarm information may also include historical maintenance records and / or recommended protective measures. The historical maintenance records include the location of the historical fault loss points of the optical cable, the cause of the historical fault loss and the historical protective measures taken.

[0045] It is understandable that when the monitoring data of the first fiber core is obtained, the analysis of the first fiber core monitoring data can be performed in the background or in the alarm function interface of the optical cable monitoring device, while the monitoring function interface of the optical cable monitoring device is executed according to the remaining target monitoring tasks in the task configuration list, so as to realize multi-threaded operation.

[0046] In this embodiment of the invention, multi-port polling detection can be achieved through task configuration. The optical cable monitoring device can be controlled to switch modes according to the task configuration list, compatible with OTDR mode and vibration monitoring mode, and automatically switching the working mode of optical cable monitoring. In practical applications, by polling the vibration monitoring task in the task monitoring list, it can identify that the currently polled port under test is vibrating near the optical cable under test, thus providing an early warning. Upon the occurrence of a vibration alarm trigger signal, fiber core monitoring is immediately performed on that port, generating alarm information, achieving early warning of faults, improving the mode switching speed for fault identification, increasing the flexibility of task configuration in the optical cable monitoring system, realizing automatic multi-port polling monitoring, automatically adjusting tasks upon the occurrence of alarm signals, improving the fault location efficiency of the optical cable monitoring system, and expanding the applicability of the optical cable monitoring system.

[0047] Please see Figure 2 Another embodiment of the optical cable monitoring method in this invention includes:

[0048] 201. Configure tasks for each port to be tested on the optical cable monitoring equipment to obtain a task configuration list.

[0049] In this embodiment, the optical cable monitoring system is also connected to an optical power device. The optical power device includes multiple second ports (or second channels), or there may be multiple optical power devices. Each optical power device provides a second port, and each second port is connected to the corresponding optical cable under test. The first port and the second port correspond one-to-one. The optical cable under test is monitored by the optical cable monitoring device and the optical power device respectively.

[0050] In this embodiment, one or more optical power devices are used to monitor the power of all optical cables under test in real time, so that when the power of any second port is lower than a preset threshold, an optical power alarm trigger signal can be generated in time to quickly switch the working mode for real-time testing.

[0051] The optical cable monitoring system establishes the association between each first port and each second port, obtaining at least one port to be tested and the corresponding association for each port to be tested. The first port is the port where the optical cable monitoring device connects to the optical cable to be tested, and the second port is the port where the optical power device connects to the optical cable to be tested. A vibration monitoring task is created for each port to be tested, and the vibration monitoring task information corresponding to each port is determined, resulting in a vibration monitoring task list. A fiber core monitoring task is created for each port to be tested, and the fiber core monitoring task information corresponding to each port is determined, resulting in a fiber core monitoring task list. A task configuration list is generated based on the vibration monitoring task list and the fiber core monitoring task list.

[0052] In one feasible implementation, a task configuration list is obtained by inserting the task information of each fiber core monitoring task in the fiber core monitoring task list into the corresponding test position in the vibration monitoring task list.

[0053] Optionally, the vibration monitoring task list can be queued according to the test start time corresponding to each fiber core monitoring task in the fiber core monitoring task list to obtain a task configuration list.

[0054] Optionally, a task configuration list can be obtained by inserting the test start time and test cycle of the fiber core monitoring task corresponding to each port to be tested in the fiber core monitoring task list into the corresponding test position in the vibration monitoring task list.

[0055] 202. Control the optical cable monitoring equipment to switch modes according to the task configuration list, and execute the target monitoring task for the corresponding port to be tested, so as to obtain the optical cable monitoring data corresponding to each port to be tested.

[0056] When the vibration monitoring task in the task configuration list is executed, the optical cable monitoring device is controlled to enter the vibration monitoring mode and perform vibration monitoring on the ports to be tested in sequence to obtain the vibration monitoring data corresponding to each port to be tested. When the fiber core monitoring task in the task configuration list is executed, the optical cable monitoring device is controlled to enter the OTDR mode and perform fiber core monitoring on the ports to be tested corresponding to the fiber core monitoring task to obtain the fiber core monitoring data corresponding to the ports to be tested. The process is repeated for each target monitoring task in the task configuration list to obtain the optical cable monitoring data corresponding to each port to be tested.

[0057] If the task types of two consecutive target test tasks are different in the task configuration list, the optical cable test system will generate a mode switching signal and send it to the optical cable monitoring device to control the optical cable monitoring device to switch working modes. Also, according to the test order of the port to be tested in the task configuration list, if the port numbers of the two consecutive target test tasks are identified to be different, the optical cable test system will generate a port switching signal and send it to the optical cable monitoring device, and the optical cable monitoring device will switch ports.

[0058] 203. When an optical power alarm trigger signal is received from the optical power device, determine the corresponding target second port to be tested.

[0059] For real-time monitoring of faults not caused by vibration, and faults not currently polled to the port to be tested (including ports that have completed the target monitoring task or ports that have not yet completed the target monitoring task), the optical cable monitoring system determines the corresponding target second port to be tested when it receives the optical power alarm trigger signal sent by the optical power device.

[0060] Specifically, when an optical power alarm trigger signal is received from any second port of the optical power device, the first port of the optical cable monitoring device is determined according to the association relationship of each port to be tested, and the first port is determined as the target second port to be tested.

[0061] It should be further explained that the target second port to be tested may be the first port currently polled, or it may be the first port that has not been polled or has been tested. If it is the first port currently polled, there is no need to switch ports. This embodiment does not impose specific restrictions on whether the target second port to be tested is the first port currently polled.

[0062] 204. Control the optical cable monitoring equipment to pause the execution of the task configuration list, and perform the fiber core monitoring task on the second target port to be tested to obtain the second fiber core monitoring data.

[0063] The optical cable monitoring system determines the current working mode of the optical cable monitoring device based on the task configuration list. If the current working mode of the optical cable monitoring device is vibration monitoring mode, it controls the optical cable monitoring device to pause the execution of the task configuration list and switch to OTDR mode to perform fiber core monitoring task on the target second test port to obtain the second fiber core monitoring data. If the current working mode of the optical cable monitoring device is OTDR mode, it switches to the target second test port to perform fiber core monitoring task when the fiber core monitoring task of the current test port is completed, and obtains the second fiber core monitoring data.

[0064] Specifically, if the task type corresponding to the current port in the task configuration list is a vibration monitoring task, since the test duration of the vibration monitoring task is relatively long, the optical cable monitoring device is controlled to pause the vibration monitoring task, delete the vibration test data of the current port, create a fiber core monitoring task corresponding to the target second port to be tested, insert it into the previous test sequence of the vibration monitoring task of the current port, and control the optical cable monitoring device to switch from vibration monitoring mode to OTDR mode to execute the fiber core monitoring task on the target second port to be tested, and obtain the second fiber core monitoring data corresponding to the target second port to be tested.

[0065] Specifically, if the task type corresponding to the current port in the task configuration list is a fiber core monitoring task, since the test duration of the fiber core monitoring task is short, the fiber core monitoring task corresponding to the target second test port is created and inserted into the next test order of the vibration monitoring task of the current port. Then, when the fiber core monitoring task of the current test port is completed, the process switches to the target second test port to execute the fiber core monitoring task and obtain the second fiber core monitoring data.

[0066] Optionally, if the task type corresponding to the current port in the task configuration list is a fiber core monitoring task, then pause the target monitoring task corresponding to the current port, create a fiber core monitoring task corresponding to the second target port to be tested, insert it into the previous test order of the fiber core monitoring task of the current port, and directly switch to the second target port to be tested to execute the fiber core monitoring task and obtain the second fiber core monitoring data.

[0067] 205. If a second fault point is determined based on the second fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed.

[0068] The processing procedure for the second fiber core monitoring data in this embodiment can be performed with reference to the processing procedure for the first fiber core monitoring data in step 105, and will not be repeated here.

[0069] 206. When a vibration alarm trigger signal is generated based on the optical cable monitoring data of any one of the ports to be tested, the port to be tested is identified as the first target port to be tested, and the optical cable monitoring equipment is controlled to suspend the execution of the task configuration list.

[0070] 207. Control the optical cable monitoring equipment to switch to OTDR mode, perform fiber core monitoring on the first target port to be tested, and obtain the first fiber core monitoring data corresponding to the first target port to be tested.

[0071] 208. If a first fault point is determined based on the first fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed.

[0072] Steps 206-208 can be performed by referring to steps 103-105, and will not be repeated here.

[0073] It should be further noted that this application does not restrict the order in which the optical power alarm trigger signal and the vibration alarm trigger signal appear. If the vibration alarm trigger signal appears first and the optical power alarm trigger signal appears later during the execution of the task configuration list, steps 206-207 of this embodiment can also be executed after step 202 and before step 203.

[0074] In this embodiment, multi-port polling detection can be achieved through task configuration. The optical cable monitoring equipment can switch modes according to the task configuration list, compatible with OTDR mode and vibration monitoring mode, and automatically switching the working mode of optical cable monitoring. Upon the occurrence of a vibration alarm trigger signal, fiber core monitoring is immediately performed on the port, generating alarm information and providing early warning of faults. Furthermore, real-time monitoring is achieved through optical power equipment. Upon the occurrence of an optical power alarm trigger signal, fiber core monitoring is immediately performed on the port, generating alarm information. Optical power alarms can be generated for both currently polled ports and non-currently polled ports, promptly identifying fault risks, improving the response speed to different faults, increasing the mode switching speed for fault identification, and enhancing the flexibility of task configuration in the optical cable monitoring system. This achieves automatic multi-port polling monitoring, automatically adjusting tasks upon the occurrence of alarm signals, improving the fault location efficiency of the optical cable monitoring system, and expanding the applicability of the optical cable monitoring system.

[0075] Please see Figure 3 Another embodiment of the optical cable monitoring method in this invention includes:

[0076] 301. Configure tasks for each port to be tested on the optical cable monitoring equipment to obtain a task configuration list.

[0077] 302. Control the optical cable monitoring equipment to switch modes according to the task configuration list, and execute the target monitoring task for the corresponding port to be tested, so as to obtain the optical cable monitoring data corresponding to each port to be tested.

[0078] 303. When a vibration alarm trigger signal is generated based on the optical cable monitoring data of any one of the ports to be tested, the port to be tested is identified as the first target port to be tested, and the optical cable monitoring equipment is controlled to suspend the execution of the task configuration list.

[0079] 304. Control the optical cable monitoring equipment to switch to OTDR mode, perform fiber core monitoring on the first target port to be tested, and obtain the first fiber core monitoring data corresponding to the first target port to be tested.

[0080] 305. If a first fault point is determined based on the first fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed.

[0081] 306. When an optical power alarm trigger signal is received from the optical power device, determine the corresponding target second port to be tested.

[0082] 307. Control the optical cable monitoring equipment to pause the execution of the task configuration list, and perform the fiber core monitoring task on the second target port to be tested to obtain the second fiber core monitoring data.

[0083] 308. If a second fault point is determined based on the second fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed.

[0084] Steps 301-308 can be performed by referring to steps 201-208, and will not be repeated here.

[0085] 309. Create a name-based test task for any port to be tested based on the alarm information of the port to be tested, and add the name-based test task to the first position in the current task configuration list.

[0086] In practical applications, there may be one or more alarm messages to be processed in the optical cable monitoring system. Before arranging staff to perform optical cable maintenance, in order to avoid false alarms in the alarm triggering signals, further improve the reliability of alarm information, and reduce the workload of staff, the optical power monitoring system can create a named test task for any port to be tested based on the alarm information of any port to be tested, and put the named test task in the first position of the current task configuration list.

[0087] This embodiment does not limit the number of name-calling test tasks. If there are n name-calling test tasks, the n name-calling test tasks will be placed in the first n positions of the current task configuration list, so as to control the optical cable monitoring equipment to execute the name-calling test tasks first, and then execute the remaining target monitoring tasks.

[0088] The number of the above-mentioned name-and-name test tasks is only related to the number of ports that generate alarm information. Optionally, all ports to be tested corresponding to alarm information can be filtered according to the port number to obtain at least one target third port to be tested. Name-and-name test tasks are created for at least one target third port to be tested to avoid repeated testing of the same port to be tested, thereby reducing the workload and the running resources consumed by name-and-name testing.

[0089] Optionally, the optical power monitoring system can create a named test task for only one or some of the alarm messages corresponding to the ports selected by the user.

[0090] It is understood that the type of alarm trigger signal corresponding to the alarm information in this embodiment is not limited. One or more point-name test tasks can be created based on one or more alarm information corresponding to one or more vibration alarm trigger signals, one or more point-name test tasks can be created based on one or more alarm information corresponding to one or more optical power alarm trigger signals, or one or more point-name test tasks can be created based on two types of alarm trigger signals.

[0091] It should be further clarified that there is not a one-to-one quantitative relationship between vibration alarm trigger signals and alarm information, or between optical power alarm trigger signals and alarm information. Each alarm trigger signal (including vibration alarm trigger signals and optical power alarm trigger signals) may generate one or more alarm information. Similarly, there is not a one-to-one quantitative relationship between alarm information and designated test tasks. There may be multiple alarm information that correspond to only one port to be tested. In this case, only one designated test task needs to be created. Alternatively, multiple alarm information may correspond to different ports to be tested, but the staff may only select one or some of the ports to be tested to create a designated test task.

[0092] 310. Control the optical cable monitoring equipment to perform fiber core monitoring on the port to be tested according to the test task, and obtain the third fiber core monitoring data of the port to be tested.

[0093] Understandably, the priority of the named test task is higher than that of the target monitoring task in the task configuration list. When a named test task exists, the optical cable monitoring device is controlled to pause the execution of the task configuration list and enter OTDR mode to perform fiber core monitoring on the third test port of each target, thereby obtaining the third fiber core monitoring data corresponding to the third test port of each target.

[0094] In one feasible implementation, a periodic curve is constructed for the monitoring data of the third fiber core corresponding to each target third test port, and the periodic curve of each target third test port is compared with the corresponding reference curve to determine whether there is a third fault point. If the fault event of the third fault point is the same as or similar to the first fault point (or second fault point) of the corresponding target third test port, for example, the distance difference between the event locations of the two fault points is less than a preset value, then the alarm information is confirmed and the target alarm information is obtained.

[0095] If there are multiple target test tasks, control the optical cable monitoring equipment to enter OTDR mode, and perform fiber core monitoring on the third port to be tested of each target in the order of testing, and then continue to execute the remaining target monitoring tasks in the task configuration list.

[0096] In this embodiment, if no optical power alarm trigger signal and / or vibration alarm trigger signal are received, this embodiment can poll according to the task configuration list. When the current task configuration list is completed, a task completion signal is generated. The roll call test function for specific ports is not opened. When roll call test is required, staff can create a target monitoring task for a specified port and adjust the test order to achieve roll call test.

[0097] It should be further explained that this embodiment only provides a scenario where alarm information caused by both vibration alarm trigger signal and optical power alarm exists simultaneously. In actual application, when alarm information occurs at any port to be tested, the point-to-point test function of that port can be enabled. That is, it is not necessary to wait for all target monitoring tasks in the task configuration list to be completed, nor is it necessary to create a point-to-point test task only when vibration alarm and optical power alarm occur.

[0098] In this embodiment, multi-port polling detection can be achieved through task configuration. The optical cable monitoring equipment can switch modes according to the task configuration list, compatible with OTDR mode and vibration monitoring mode, and automatically switching the working mode of optical cable monitoring. Upon the occurrence of a vibration alarm trigger signal, fiber core monitoring is immediately performed on the port, generating alarm information and providing early warning of faults. Furthermore, real-time monitoring is achieved through optical power equipment. Upon the occurrence of an optical power alarm trigger signal, fiber core monitoring is immediately performed on the port, generating alarm information. Optical power alarms can be generated for both currently polled and non-currently polled ports, promptly identifying fault risks and improving the response speed to different faults. The mode switching speed for fault identification is also improved. Automatic task adjustment is performed upon the occurrence of alarm signals, improving the fault location efficiency of the optical cable monitoring system. Furthermore, a designated testing function is set up to perform secondary confirmation of alarm information, ensuring the accuracy of fault location in the optical cable monitoring system, reducing the false alarm rate of alarm signals, and improving the flexibility of task configuration in the optical cable monitoring system. This achieves automatic multi-port polling monitoring and expands the applicability of the optical cable monitoring system.

The storage medium is located in memory 601. Processor 600 reads the information in memory 601 and, in conjunction with its hardware, completes the method steps of the aforementioned embodiment, as follows:

[0137] Each port to be tested of the optical cable monitoring device is configured with a task configuration list. Based on the task configuration list, the optical cable monitoring device is controlled to switch modes and execute the target monitoring task for the corresponding port, obtaining optical cable monitoring data for each port. When a vibration alarm trigger signal is generated based on the optical cable monitoring data of any port, the port to be tested is designated as the first target port, and the optical cable monitoring device is controlled to pause the execution of the task configuration list. The optical cable monitoring device is then switched to OTDR mode to perform fiber core monitoring on the first target port, obtaining the first fiber core monitoring data corresponding to the first target port. If a first fault point is determined based on the first fiber core monitoring data, an alarm message is generated, and the remaining target monitoring tasks in the task configuration list are executed. This embodiment enables multi-port polling detection through task configuration. It controls the optical cable monitoring equipment to switch modes according to the task configuration list, and is compatible with OTDR mode and vibration monitoring mode. It also enables automatic switching of the working mode of optical cable monitoring. When a vibration alarm trigger signal is detected, the fiber core of the port is monitored immediately to generate alarm information, realize early warning of faults, improve the mode switching speed of fault identification, improve the compatibility and flexibility of the optical cable monitoring system, and expand the application scope of the optical cable monitoring system.

[0138] After controlling the optical cable monitoring device to switch modes according to the task configuration list and execute the target monitoring task for the corresponding port to be tested, and obtaining the optical cable monitoring data for each port to be tested, the method further includes: when receiving an optical power alarm trigger signal sent by the optical power device, determining the corresponding target second port to be tested; controlling the optical cable monitoring device to pause the execution of the task configuration list and execute the fiber core monitoring task for the target second port to be tested, obtaining the second fiber core monitoring data; if a second fault point is determined to exist based on the second fiber core monitoring data, generating an alarm message and continuing to execute the remaining target monitoring tasks in the task configuration list. In this embodiment, when an optical power alarm trigger signal occurs, the device automatically switches according to the current working mode and port, and automatically analyzes the second fiber core monitoring data to promptly identify fault risks and improve the response speed to different fault identifications.

[0139] After generating the alarm information as described above, the process further includes: creating a designated test task for any port under test based on the alarm information of that port, and placing the designated test task in the first position of the current task configuration list; controlling the optical cable monitoring equipment to perform fiber core monitoring on the port under test according to the designated test task, and obtaining the third fiber core monitoring data of the port under test. This embodiment uses the designated test function to perform secondary confirmation of the alarm information, ensuring the accuracy of the alarm information, reducing the false alarm rate, improving the compatibility and flexibility of the optical cable monitoring system, and expanding the application scope of the optical cable monitoring system.

[0140] The above-mentioned task configuration for each port to be tested of the optical cable monitoring device yields a task configuration list, including: establishing the association between each first port and each second port, obtaining at least one port to be tested and the corresponding association for each port, where the first port is the port corresponding to the connection between the optical cable monitoring device and the optical cable to be tested, and the second port is the port corresponding to the connection between the optical power device and the optical cable to be tested; creating a vibration monitoring task for each port to be tested and determining the vibration monitoring task information corresponding to each port, resulting in a vibration monitoring task list; creating a fiber core monitoring task for each port to be tested and determining the fiber core monitoring task information corresponding to each port, resulting in a fiber core monitoring task list; and generating a task configuration list based on the vibration monitoring task list and the fiber core monitoring task list. This embodiment achieves the association between the optical cable monitoring device and the optical power device through task configuration, enabling multi-port polling detection, controlling the optical cable monitoring device to switch modes according to the task configuration list, improving the compatibility and flexibility of the optical cable monitoring system, and expanding the applicability of the optical cable monitoring system.

[0141] The above-mentioned generation of a task configuration list based on the vibration monitoring task list and the fiber core monitoring task list includes: inserting the task information of each fiber core monitoring task in the fiber core monitoring task list into the corresponding test position in the vibration monitoring task list to obtain the task configuration list. This embodiment, by inserting fiber core monitoring tasks into the queue, enables the optical cable monitoring system to be compatible with both OTDR mode and vibration monitoring mode, improving the compatibility and flexibility of the optical cable monitoring system and expanding its applicability.

[0142] The aforementioned control of the optical cable monitoring device to pause the execution of the task configuration list and perform fiber core monitoring on the target second test port to obtain second fiber core monitoring data includes: if the current working mode of the optical cable monitoring device is vibration monitoring mode, then the control of the optical cable monitoring device to pause the execution of the task configuration list and switch to OTDR mode to perform fiber core monitoring on the target second test port to obtain second fiber core monitoring data; if the current working mode of the optical cable monitoring device is OTDR mode, then when the fiber core monitoring task of the current test port is completed, the control switches to the target second test port to perform fiber core monitoring to obtain second fiber core monitoring data. In this embodiment, when an optical power alarm trigger signal occurs, the corresponding switching operation is performed according to the current working mode and port. The target second test port performs fiber core monitoring on the port, generates alarm information, and improves alarm efficiency. Optical power alarms can be implemented for both the currently polled test port and the test ports not currently polled, enabling timely identification of fault risks and improving the response speed to different fault identifications.
