[0037] Through the hidden danger management module, the hidden danger situation on each of the optical fibers to be monitored can be recorded, which is convenient for subsequent hidden danger investigation and is beneficial to the dumb resource management of optical fibers.

[0038] Furthermore, the operation and maintenance system also includes an optical fiber quality management module;

[0039] The optical fiber quality management module is used for:

[0040] The loss condition of the corresponding optical fiber to be monitored is obtained according to the operation and maintenance data.

[0041] Further, judging the fault type of the optical fiber to be monitored according to the real-time waveform curve specifically includes:

[0042] Determine the fault type of the optical fiber to be monitored according to the front-end waveform image and the end waveform image of the real-time waveform curve, wherein the front-end waveform image and the end waveform image are obtained by dividing the real-time waveform curve according to preset boundaries;

[0043] The step of determining the fault type of the optical fiber to be monitored according to the front-end waveform image and the end-end waveform image of the real-time waveform curve specifically includes:

[0044] Obtaining a first peak width of the front-end waveform image, and if the first peak width is greater than a preset peak width threshold, determining that the fault type of the optical fiber to be monitored is poor contact of the starting port;

[0045] If the first Fresnel reflection peak does not exist in the terminal waveform image, it is determined that the fault type of the optical fiber to be monitored is that the optical fiber to be monitored is severely damaged or broken.

[0046] By judging the fault type of the optical fiber to be monitored based on the front-end waveform image and the back-end waveform image of the real-time waveform curve, the fault type of the optical fiber to be monitored can be determined more accurately, providing a more detailed problem location for subsequent fault handling, reducing inefficient manual troubleshooting, and improving the efficiency of optical fiber fault repair work.

[0047] Further, judging the fault type of the optical fiber to be monitored according to the real-time waveform curve further includes:

[0048] If there is a loss waveform whose drop exceeds a preset threshold in the middle waveform image, it is determined that the fault type of the optical fiber to be monitored is damage or poor fiber fusion at the position corresponding to the loss waveform;

[0049] The middle waveform image is a waveform image between the front waveform image and the end waveform image.

[0050] The middle waveform image can reflect the loss of the optical fiber to be monitored. If a loss waveform with a drop exceeding a preset threshold value appears, it can be determined that the optical fiber position corresponding to the loss waveform is damaged or poorly fused. Based on the above determination, a method for locating optical fiber damage or poorly fused fiber is provided for troubleshooting access problems, and the problem can be handled in advance before formal inspection and maintenance, ensuring the smooth progress of formal inspection and maintenance work.

[0051] Further, after determining the fault type of the optical fiber to be monitored according to the real-time waveform curve, the method further includes:

[0052] If there is a second Fresnel reflection peak in the middle waveform image, it is determined that there is a fiber jumper at the position corresponding to the second Fresnel reflection peak. The middle waveform image can also reflect the jumper status of the optical fiber to be monitored. If there is a second Fresnel reflection peak in the middle waveform image, it can be determined that there is a fiber jumper at the position corresponding to the second Fresnel reflection peak. Based on the above determination, a method for locating jumpers is provided for troubleshooting access problems, and the situation can be recorded in advance before formal inspection and maintenance, ensuring a clear prediction of the situation of the optical fiber to be monitored during formal inspection and maintenance.

[0053] Further, after determining the fault type of the optical fiber to be monitored according to the real-time waveform curve, the method further includes:

[0054] If the first Fresnel reflection peak exists in the terminal waveform image, and the terminal of the first Fresnel reflection peak is connected to a secondary peak, it is determined that the optical fiber to be monitored has been terminated;

[0055] The peak value of the secondary wave peak is lower than the peak value of the first Fresnel reflection peak.

[0056] The terminal waveform image can also reflect the termination status of the optical fiber to be monitored. According to the above judgment, a method for locating the termination of the optical fiber is provided for troubleshooting access problems. The optical fiber status can be recorded in advance before formal inspection and operation and maintenance, ensuring the smooth progress of formal inspection and operation and maintenance work.

[0057] Furthermore, the work order review module is also used to obtain the evaluation status of the detection point and add the evaluation status to the work order processing data;

[0058] The acquisition of the evaluation situation specifically includes:

[0059] If the type of the operation and maintenance work order is a census work order type, then the horizontal distance between the detection point and another previously set detection point is calculated based on the setting position of the detection point, wherein the detection points are sequentially set on the corresponding optical cables of the optical fiber to be monitored; the horizontal distance between the detection point and another detection point is compared with a preset maximum distance threshold to obtain the evaluation status of the detection point; if the type of the operation and maintenance work order is a fiber core inventory work order type, then the physical properties of the detection point are obtained as the evaluation status of the detection point; if the type of the operation and maintenance work order is a fault repair work order type, then the environmental conditions of the detection point are obtained as the evaluation status of the detection point.

[0060] In the survey work order type, a certain distance limit is met between one detection point and another detection point. If the distance between the two detection points is too large, there will be errors in obtaining the condition of the optical fiber to be monitored based on the detection data of the two detection points. For example, to measure the loss value of a section of optical fiber, the two detection points need to meet the preset distance, and the loss value is of reference significance; in the core inventory work order type, the physical properties of the detection point will affect the accuracy of the core inventory. The physical properties of the detection point include whether the power supply of the detection point is normal, whether the interface is normal, etc. These physical properties will affect the core inventory, and they need to be used as an evaluation to assist the audit work; in the fault repair work order type, the environmental conditions of the detection point will affect the judgment of the detection point on the fault repair, such as large noise interference, the rationality of the detection position, etc., which will affect the analysis of the fault repair, and they need to be used as an evaluation to assist the audit work. According to the setting of the detection point, an auxiliary indicator is provided for the audit work of the optical cable operation and maintenance work order. The setting of the evaluation detection point can add dimensional judgment to the audit work and reduce the misjudgment rate of the audit.

[0061] Furthermore, comparing the horizontal distance between the detection point and another detection point with a preset maximum distance threshold to obtain an evaluation condition of the detection point specifically includes:

[0062] If the horizontal distance between the detection point and another detection point is lower than a preset maximum distance threshold, the evaluation conditions corresponding to the detection point and another detection point are marked as legal;

[0063] If the horizontal distance between the detection point and another detection point is greater than a preset maximum distance threshold, the evaluation situations corresponding to the detection point and another detection point are marked as illegal.

[0064] By judging the distance, legal and illegal detection points are set, and this is used as the evaluation result of the route survey work order, which can provide reminders for the detection work and provide an audit material for the audit work.

[0065] Furthermore, the operation and maintenance work order corresponding to the work order processing data is reviewed, specifically:

[0066] In combination with the detection parameters and evaluation conditions corresponding to the detection points, the work order processing data is reviewed to obtain the analysis results of the detection points;

[0067] The obtaining of the analysis result corresponding to the detection point specifically includes:

[0068] If the detection task is to survey the routing points of the optical cable corresponding to the optical fiber to be monitored, the overall routing situation of the corresponding optical cable is obtained according to the work order processing data, and the overall routing situation of the corresponding optical cable is used as the analysis result;

[0069] If the detection task is to detect the core usage status of the optical fiber to be monitored or the usage status of the ODF rack corresponding to the optical fiber to be monitored, the core arrangement record of the corresponding optical cable is obtained according to the work order processing data, and the core status arrangement record of the corresponding optical cable is used as the analysis result;

[0070] If the detection task is to troubleshoot the fault of the fiber core to be monitored, the fault processing status of the fiber core to be monitored is obtained according to the work order processing data, and the fault processing status of the optical cable is used as the analysis result.

[0071] Different detection tasks require different feedback. For the detection task of surveying the routing points of the corresponding optical cable of the optical fiber to be monitored, it is necessary to analyze whether the operation of multiple detection points of the corresponding optical cable is normal, and feedback the overall routing of the optical cable; for the detection task of detecting the core usage status of the optical fiber to be monitored or the usage of the ODF rack corresponding to the corresponding optical cable, it is necessary to count the core status arrangement of the corresponding optical cable within the range, record the newly added or deleted optical fibers, and feedback the specific usage of the optical fibers within the range; for the detection task of troubleshooting the fault of the optical fiber to be monitored, it is necessary to analyze the detection data of the detection points near the fault, determine the specific fault type and location, and feedback the fault status of the optical fiber to be monitored. Different types of analysis results are necessary standards for reviewing the optical cable operation and maintenance work order and accepting the entire detection work, which optimizes the complex steps of optical cable operation and maintenance and provides accurate and detailed operation and maintenance information for optical cable operation and maintenance.

[0072] Compared with the prior art, the present invention has the following beneficial effects:

[0073] The present invention uses the data acquisition module to poll and monitor the plurality of optical fibers to be monitored and collect the operation and maintenance data of the optical fibers to be monitored, so as to generate a real-time waveform curve corresponding to the optical fibers to be monitored according to the operation and maintenance data, and to analyze and judge the fault type of the optical fibers to be monitored according to the real-time waveform curve; wherein, by arranging a large amount of the operation and maintenance data to obtain the real-time waveform curve, the intuitive characteristics of the curve image can be used to intuitively and quickly judge the fault type of the optical fibers to be monitored. The work order construction module uses the fault type of the optical fibers to be monitored, and uses the routing conditions and core usage status of the optical fibers to be monitored to respectively construct a plurality of different types of operation and maintenance work orders, so that the staff can perform corresponding processing according to different types of the operation and maintenance work orders, thereby improving the efficiency of the operation and maintenance work order processing. In addition, in the process of processing the work order, by setting a detection point within the area where the optical fibers to be monitored are set, and by reviewing the operation and maintenance work order through the detection data of the detection point and the corresponding location information, the specific detection data can more accurately realize the review of the operation and maintenance work order, thereby improving the reliability of the operation and maintenance system.

DETAILED DESCRIPTION

[0077] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0078] Example 1

[0079] like Figure 1 As shown, this embodiment provides an optical cable operation and maintenance system, and the operation and maintenance system may specifically include:

[0080] The data collection module 1 is used to perform polling monitoring on a plurality of optical fibers to be monitored in a polling order, and collect the operation and maintenance data of the polled optical fibers to be monitored;

[0081] It is understandable that the polling order is a basic resource scheduling and resource allocation mechanism, which ensures the fairness and stability of the entire workflow by accessing or processing multiple objects in sequence according to certain rules. In this embodiment, the polling order is obtained according to the plurality of optical fibers to be monitored, and a fair and equal polling opportunity is provided for each optical fiber to be monitored, ensuring that each optical fiber to be monitored can be monitored, and ensuring comprehensive operation and maintenance of the plurality of optical fibers.

[0082] The acquisition of the polling order may specifically include:

[0083] First, obtain the interface number corresponding to each optical fiber to be monitored;

[0084] It is understandable that in the present embodiment, an optical time domain reflectometer is used for monitoring. The interface number is an identifier of each interface on the optical time domain reflectometer. The optical time domain reflectometer can be externally connected to the plurality of optical fibers to be monitored to monitor the optical fibers to be monitored. For the plurality of optical fibers to be monitored connected to the same optical time domain reflectometer, in order to facilitate the distinction, the interface number on the optical time domain reflectometer is used to correspond one-to-one with the optical fibers to be monitored, so as to achieve the effect of quickly locating one of the optical fibers to be monitored. It is understandable that before the optical fiber to be monitored is connected to the optical time domain reflectometer for monitoring, it is necessary to bind and record the interface number on the optical fiber to be monitored and the optical time domain reflectometer in advance, so as to ensure the correct arrangement of the polling order and the one-to-one correspondence when the monitoring data generated by each optical fiber to be monitored is subsequently uploaded.

[0085] After the corresponding interface numbers are obtained, a polling order is obtained for the interface numbers according to a preset interface arrangement rule.

[0086] It is understandable that in this embodiment, it is necessary to pre-record the one-to-one relationship between the interface number and the optical fiber to be monitored and pre-set the interface arrangement rules; obtain the interface number of the optical fiber to be monitored, sort the interface number according to the interface arrangement rules, and obtain an interface number sorting table, and the interface number sorting table is processed to obtain the polling order that can be executed.

[0087] In this embodiment, the polling monitoring specifically includes:

[0088] Setting the monitoring time interval and monitoring pulse width of each optical fiber to be monitored;

[0089] Next, the plurality of optical fibers to be monitored are monitored in sequence according to the polling sequence and the monitoring pulse width and at the monitoring time interval.

[0090] It is understandable that the monitoring time interval is the time required for a monitored optical fiber to complete a monitoring task. For the monitoring of a monitored optical fiber, continuous monitoring is required to obtain continuous data in order to obtain the data changes in the monitored optical fiber. The monitoring time interval is set according to operation and maintenance needs. It is understandable that a monitoring time interval that is too short will affect the integrity of the recovered optical fiber data; the monitoring time interval should not be too long to affect the efficiency of the entire polling monitoring;

[0091] In this embodiment, the monitoring pulse width of each optical fiber to be monitored also needs to be set. It is understandable that the time length of the optical pulse of the optical time domain reflectometer can also be converted into the spatial length of the pulse on the optical fiber. According to the basic properties of each optical fiber to be monitored, the monitoring pulse width of the optical fiber to be monitored is adaptively set to ensure the stability and reliability of the monitoring work, and can improve the monitoring accuracy of each optical fiber to be monitored, thereby improving the quality of the monitoring work.

[0092] A curve generating module 2, used for generating a real-time waveform curve corresponding to the optical fiber to be monitored according to the operation and maintenance data;

[0093] It is understandable that the real-time waveform curve reflects the real-time link status and performance of the monitored optical fiber during monitoring. The real-time curve is generated based on the operation and maintenance data received in real time by polling monitoring, which can help operation and maintenance personnel observe the real-time operation of the currently monitored optical fiber.

[0094] In this embodiment, the data acquisition module 1 is also used for:

[0095] Obtaining a roll call monitoring instruction, the roll call monitoring instruction including a first roll call optical fiber, pausing the polling monitoring according to the roll call monitoring instruction, and performing roll call monitoring on the first roll call optical fiber, and continuing the polling monitoring after completing the roll call monitoring;

[0096] The data processing module is also used to generate a corresponding naming waveform curve according to the naming data of the first naming optical fiber.

[0097] In this embodiment, the roll call monitoring means monitoring of the designated optical fiber, wherein the designated optical fiber is the optical fiber whose real-time operation status needs to be queried immediately. It is understandable that the polling monitoring is a continuous execution process. As mentioned above, this process will monitor the optical fiber to be detected according to the preset polling order, and each optical fiber has a certain monitoring time interval. After polling a fiber to be monitored, it may take a long time to present the curve image of the optical fiber to be monitored again; at the same time, in some emergency situations where a sudden monitoring of a certain optical fiber to be monitored is required, it is impossible to monitor the optical fiber to be monitored in time through polling monitoring, and it is also impossible to implement fixed-point monitoring on the optical fiber to be monitored (because polling will switch to the next optical fiber), so it is necessary to be able to jump monitoring for a specific function of the optical fiber to be monitored. It is understandable that the roll call monitoring instruction contains the basic information of the first roll call optical fiber specified by the operator, and the background can locate the interface number connected to the first roll call optical fiber according to the basic information, and perform roll call monitoring on the first roll call optical fiber. It is understandable that before the roll call monitoring starts, the polling monitoring needs to be suspended to prevent conflicts between the two monitoring.

[0098] It is understandable that before pausing the polling monitoring, the polling progress of the polling monitoring needs to be maintained so that when the polling monitoring continues to be executed, it can continue to run from the position where it was interrupted last time. Therefore, it is necessary to record the current position of the polling sequence reading so that when the polling monitoring is executed next time, it can continue to read from the current position of the polling sequence.

[0099] The curve generating module 2 is further used to monitor the real-time waveform curve, and when the real-time waveform curve changes, a historical waveform curve corresponding to the optical fiber to be monitored is generated according to the changed real-time waveform curve.

[0100] It is understandable that the historical waveform curve reflects the historical link status and performance of the optical fiber to be monitored during monitoring. The historical waveform curve is generated by selecting the real-time waveform curve, specifically:

[0101] Monitoring the real-time waveform curve, when the background monitors that the real-time waveform curve changes, generating a historical waveform curve corresponding to the optical fiber to be monitored from the changed real-time waveform curve, recording the time point of generating the historical waveform curve, and associating the historical waveform curve with the corresponding time point for storage;

[0102] When the background monitor detects that the real-time curve has not changed, the historical curve maintains its original value;

[0103] It is understandable that when monitoring begins, the value of the historical waveform curve is empty; as monitoring continues, the historical waveform curve corresponding to the optical fiber to be monitored may continue to increase. Since the historical waveform curve is obtained based on the changes in the real-time waveform curve, the historical waveform curve can reflect the changes in the corresponding optical fiber to be monitored over a period of time. Therefore, by obtaining the historical waveform curve at the corresponding time point, the operating status of the optical fiber to be monitored at the corresponding time point can be analyzed.

[0104] Preferably, for the roll call waveform curve, a corresponding historical waveform curve can also be generated. The generation of the historical waveform curve corresponding to the roll call waveform curve is similar to the generation of the historical waveform curve corresponding to the real-time waveform curve, which will not be further described here.

[0105] In this embodiment, the curve generating module 2 can also be used to generate a reference waveform curve according to the real-time waveform curve. Specifically, a curve image whose parameters meet a preset threshold is selected from the real-time waveform curve, and the selected curve image is set as the reference waveform curve.

[0106] It is understandable that the reference waveform curve reflects the link status and performance of the optical fiber to be monitored during normal operation. The reference waveform curve is generated based on the real-time waveform curve, which can provide an intuitive correct status benchmark for operation and maintenance personnel and provide a reference for the real-time operation of the optical fiber.

[0107] In a preferred embodiment, the curve generating module 2 is further used to visualize at least two of the real-time waveform curve, the roll call waveform curve, the historical waveform curve and the reference waveform curve;

[0108] It is understandable that the real-time waveform curve, roll call waveform curve, historical waveform curve and reference waveform curve can be displayed individually, or in combination of two or three; a single display can reflect the information originally held by the curve; multiple combinations can be displayed to more intuitively observe the changes in the curve. When multiple combinations are required, the corresponding curves can be set in the same coordinates and displayed after alignment of time and scale according to the data situation.

[0109] A fault analysis module 3, used for determining the fault type of the optical fiber to be monitored according to the real-time waveform curve;

[0110] Specifically, judging the fault type of the optical fiber to be monitored according to the real-time waveform curve may include:

[0111] Determine the fault type of the optical fiber to be monitored according to the front-end waveform image and the end waveform image of the real-time waveform curve, wherein the front-end waveform image and the end waveform image are obtained by dividing the real-time waveform curve according to preset boundaries;

[0112] It can be understood that the real-time waveform curve is divided into the front-end waveform image and the rear-end waveform image according to preset boundaries, which respectively correspond to the operating status reflections of the front and rear end positions of the optical fiber to be monitored. The real-time waveform curve is observed and judged separately, which can quickly locate the location of the fault and infer the type of fault, providing a detailed and systematic methodology for determining the fault of the optical fiber to be monitored.

[0113] In a preferred implementation of the present embodiment, the real-time waveform curve can be placed in a coordinate system for display, wherein the x-axis represents the distance between the optical time domain reflection device and each position of the optical fiber to be monitored, and the y-axis represents the reflection signal intensity of the optical fiber to be monitored. In the coordinate system, the front section area between the origin of the coordinate system and the front section position point of the predetermined length from the optical time domain reflection device is obtained, and the real-time waveform curve contained in the front section area is divided into the front-end waveform image, wherein the predetermined length from the optical time domain reflection device is set according to the parameters of the optical fiber to be monitored; the division of the front-end waveform image is to observe the starting end of the optical fiber to be monitored;

[0114] Specifically, the total length of the optical fiber to be monitored is obtained in advance, and the end position point of the end of the corresponding optical cable of the optical fiber to be monitored corresponding to the x-axis of the coordinate system is obtained according to the total length of the optical fiber to be monitored; in the coordinate system, the end position point and the area extending from the end position point are obtained, and the real-time waveform curve contained in the area is the end waveform image; the division of the end waveform image is to observe the end of the optical fiber to be monitored.

[0115] The step of determining the fault type of the optical fiber to be monitored according to the front-end waveform image and the end-end waveform image of the real-time waveform curve specifically includes:

[0116] Obtaining a first peak width of the front-end waveform image, and if the first peak width is greater than a preset peak width threshold, determining that the fault type of the optical fiber to be monitored is poor contact of the starting port;

[0117] If the first Fresnel reflection peak does not exist in the terminal waveform image, it is determined that the fault type of the optical fiber to be monitored is that the optical fiber to be monitored is severely damaged or broken.

[0118] In this embodiment, when the optical fiber to be monitored is normally connected, the front-end waveform image will not show a large-scale vibration response, that is, several vibration peaks will not appear continuously; and the first peak width does not exceed the preset normal peak width threshold. Preferably, the preset normal peak width threshold is 40m; if the first peak width is greater than the preset peak width threshold, it means that there is a large loss between the optical fiber to be monitored and the optical time domain reflection device, resulting in the first peak width exceeding the normal peak width threshold, so that the subsequent waveform is relatively stable and the waveform is abnormal, affecting the judgment of subsequent formal detection and operation and maintenance; the above-mentioned fault type can determine that the fault type of the optical fiber to be monitored is poor contact of the starting port; for the problem of poor contact at the starting end, it is generally a problem with the connector between the optical fiber to be monitored and the optical time domain reflection device, and the problem needs to be repaired;

[0119] When the optical fiber to be monitored is normally connected, the rear-end waveform image has only one obvious Fresnel reflection peak, wherein the Fresnel reflection peak is a peak value formed by a strong backscattered light signal generated by the mismatch of the refractive index at certain specific points in the optical fiber to be monitored. In this embodiment, the Fresnel reflection peak is used to reflect the state of the terminal connection position of the optical fiber to be monitored; if the first Fresnel reflection peak does not exist in the terminal waveform image, it means that the optical fiber to be monitored is seriously damaged or broken, and the pulse laser cannot continue to propagate backward. It is necessary to perform a breakpoint damage test on the optical fiber to be monitored to find out the serious damage or breakpoint of the optical fiber to be monitored.

[0120] Specifically, judging the fault type of the optical fiber to be monitored according to the real-time waveform curve further includes:

[0121] If there is a loss waveform whose drop exceeds a preset threshold in the middle waveform image, it is determined that the fault type of the optical fiber to be monitored is damage or poor fiber splicing at the position corresponding to the loss waveform;

[0122] The middle waveform image is a waveform image between the front waveform image and the terminal waveform image. In this embodiment, in the real-time waveform curve of the coordinate system, the area between the front waveform image and the terminal waveform image is obtained, and the real-time waveform curve contained in the area is the middle waveform image.

[0123] In this embodiment, there will be multiple waveform drops in the middle waveform image, but if the drops are within the loss range of a preset threshold, it is a normal propagation loss and will not have a serious impact on detection and operation and maintenance; however, if there is a loss waveform in the middle waveform image whose drop exceeds the preset threshold, it means that the position of the optical fiber to be monitored corresponding to the loss waveform is damaged or has poor fiber fusion, and the corresponding position needs to be checked and repaired; wherein, the loss waveform of the preset threshold is set as a reference based on the historical data of normal access of the optical fiber to be monitored.

[0124] Wherein, after determining the fault type of the optical fiber to be monitored according to the real-time waveform curve, the fault analysis module 3 further includes:

[0125] If there is a second Fresnel reflection peak in the middle waveform image, it is determined that there is an optical fiber jumper at a position corresponding to the second Fresnel reflection peak.

[0126] In this embodiment, the middle waveform image will have another waveform situation, that is, there is a second Fresnel reflection peak in the middle waveform image, which means that there is a jumper in the optical cable to be monitored. Fiber jumper is a connection method in optical fiber communication, which is used to transmit and distribute optical signals between different devices or optical fibers. Therefore, it is necessary to continue testing at the second Fresnel reflection peak during operation and maintenance to find the jumper position, and then record the jumper position; it is understandable that.

[0127] Furthermore, after determining the fault type of the optical fiber to be monitored according to the real-time waveform curve, the fault analysis module 3 further includes:

[0128] If the first Fresnel reflection peak exists in the terminal waveform image, and the terminal of the first Fresnel reflection peak is connected to a secondary peak, it is determined that the optical fiber to be monitored has been terminated;

[0129] The peak value of the secondary wave peak is lower than the peak value of the first Fresnel reflection peak.

[0130] In this embodiment, there is another waveform condition in the terminal waveform image, that is, the first Fresnel reflection peak exists in the terminal waveform image, and the end of the first Fresnel reflection peak is connected to a secondary peak. According to this waveform condition, it can be determined that the optical fiber to be monitored has been terminated. It is understandable that the termination of the optical fiber to be monitored refers to the introduction of the outdoor test optical fiber into the machine room, and a series of processing and connection operations are performed on it so that it can communicate normally with other communication equipment; the termination of the optical fiber to be monitored can be recorded, and in the subsequent formal inspection and operation and maintenance, there is a clear prediction of the situation of the optical fiber to be monitored.

[0131] In addition, in this embodiment, after determining the fault type of the optical fiber to be monitored according to the real-time waveform curve, the fault analysis module 3 further includes:

[0132] If the real-time waveform curve appears to be static, stuck or missing, it is determined that the optical time domain reflectometer network is unstable.

[0133] It is understandable that the real-time waveform curve is relatively static in the overall trend, but in fact, the real-time waveform curve is displayed based on the jumps of the received real-time operation and maintenance data. Therefore, when the real-time waveform curve appears static, stuck or missing, it means that there is an abnormality in the reception of the operation and maintenance data, and the network needs to be checked.

[0134] It should be noted that although the above description is about the determination and processing of the real-time waveform curve, since the point-named waveform curve can be regarded as the real-time waveform curve of the first point-named optical fiber, the point-named waveform curve is also applicable to the above-mentioned waveform division, fault determination and processing.

[0135] A work order construction module 4 is used to generate an operation and maintenance work order of a fault repair work order type according to the fault type of the optical fiber to be monitored;

[0136] In actual application, the operation and maintenance of the optical fiber to be monitored not only includes fault handling, but also includes a route survey of the optical cable corresponding to the optical fiber to be monitored, and the core status of the optical fiber to be monitored.

[0137] Therefore, in this embodiment, the work order construction module 4 is also used to construct an operation and maintenance work order of a census work order type according to the routing situation of the optical fiber to be monitored, and to construct an operation and maintenance work order of a core inventory work order type according to the core usage status of the optical fiber to be monitored;

[0138] The types of operation and maintenance work orders are described as follows:

[0139] Census work order type:

[0140] It is understandable that for an optical cable put into use, it is necessary to understand the route of the optical cable and continuously detect the health of the optical cable, so as to predict possible failures of the optical cable in advance, prepare countermeasures for the failures in advance, and minimize the losses caused by business interruptions; therefore, it is necessary to conduct a comprehensive route survey and detection of the optical cable. Specifically, a route position detection point can be set at a preset distance of the optical cable, and the route position detection point can be detected to obtain detection data. By observing whether the real-time waveform of the optical fiber responds, it is confirmed whether the optical cable passes through the route position detection point and the length of the optical cable at the route position detection point.

[0141] Fiber core inspection work order type:

[0142] It is understandable that due to the large number of optical cables put into use, in the event of emergency repair of faults or switching of spare fiber cores, the optical cable access or data may not be synchronized in time. It is necessary to conduct regular on-site inspections and checks on the use of optical cables for business, mark the optical cables that have no business but have been working, update the optical cable database, provide accurate optical cable layout for operation and maintenance work, and help to better monitor the optical cables.

[0143] Troubleshooting work order type:

[0144] It is understandable that if the optical cable cannot work normally, it is suspected that there is a fault. After the preliminary judgment of the fault type, further on-site inspection is required to accurately locate and determine the fault. It is necessary to set up nearby inspection points in the fault area to accurately troubleshoot the fault and provide accurate optical cable information and reference data for fault handling.

[0145] A work order processing module 5 is used to obtain the detection task of the optical fiber to be monitored and the area range of the optical fiber to be monitored according to the operation and maintenance work order, wherein the detection task of the operation and maintenance work order corresponds to the type of the operation and maintenance work order;

[0146] It is understandable that different types of the operation and maintenance work orders correspond to different detection tasks, and the detection tasks may specifically include:

[0147] When the type of the operation and maintenance work order is a survey work order type, surveying the routing points of the optical cables corresponding to the optical fibers to be monitored is used as the detection task;

[0148] When the type of the optical cable operation and maintenance work order is a fiber core inventory work order type, detecting the use status of the fiber core of the corresponding optical cable or the use status of the ODF rack of the corresponding optical cable is used as the detection task;

[0149] When the type of the optical cable operation and maintenance work order is a fault repair work order type, the detection task is to troubleshoot the fault type of the corresponding optical cable.

[0150] By constructing multiple types of operation and maintenance work orders corresponding to different types, and setting different inspection tasks according to the different types of operation and maintenance work orders, the inspection direction of each work order can be clarified, so that after receiving the work order and the corresponding inspection task, the inspection personnel can quickly dispatch professional maintenance personnel to the field for inspection, thereby improving the efficiency of receiving and processing work orders; furthermore, through the inspection task, the tone can be set for the subsequent audit work, and the inspection task can be used as the basis for whether the audit is passed, which also improves the efficiency of the audit.

[0151] The work order review module 6 is used to review the corresponding operation and maintenance work order according to the work order processing data;

[0152] In this embodiment, the work order processing data is obtained by binding the detection data and the corresponding detection point through location information; the detection data is obtained by detecting the detection point according to the detection parameters of the detection point and the detection task; the detection point is set within the area where the corresponding optical cable of the optical fiber to be monitored is set according to the detection task, and the detection parameters are set according to the detection point.

[0153] It is understandable that for any optical cable, within the area in which it is set, it may include some routing points. These routing points are fixed and can play a certain identification role in actual operation and maintenance detection. These routing points can be confirmed as detection points; however, there are also some situations, such as when the position to be detected does not fall on these fixed routing points, it is not possible to accurately locate the position to be detected through these existing fixed routing points, and it is necessary to reconfirm new routing points as detection points. Therefore, in this embodiment, after obtaining the operation and maintenance work order, the detection points are confirmed according to the different requirements of the detection task, which can facilitate the maintenance personnel to adaptively confirm fixed and / or non-fixed detection points according to the detection task.

[0154] Exemplarily, for the operation and maintenance work order of the survey work order type, it is necessary to conduct a survey of the key positions of the entire optical cable corresponding to the optical fiber to be monitored, and it is necessary to confirm the detection points at the routing points of the corresponding positions; preferably, a detection point can be confirmed in the machine room at the starting end of the corresponding optical cable, and then several detection points can be confirmed in sequence along the optical cable routing;

[0155] For the fiber core inspection work order, it is necessary to check the usage status of the fiber core of the corresponding optical cable or the usage of the ODF rack of the corresponding optical cable, so it is necessary to set up inspection points in places where a large number of optical cables are accessed / transferred, such as machine rooms, optical cable wells, etc.

[0156] For a fault repair work order, it is necessary to perform fault repair and troubleshooting on the fault point of the corresponding optical cable, and it is necessary to set up a detection point near the fault point in order to accurately obtain the location of the fault and repair it.

[0157] In this embodiment, the detection point can be confirmed on site, and the detection parameters can be set according to the optical cable attribute information and environmental conditions of the corresponding detection point. The attribute information of the corresponding optical cable needs to be input in advance before the detection. The attribute information may include the length of the optical cable, the host selected for detection, the optical cable port, and the census direction, etc. The attribute information is the background of the detection work record detection, which is convenient for quickly locating the basic situation of the detection work during the audit work.

[0158] Furthermore, the work order review module 6 is also used to obtain the evaluation status of the detection point and add the evaluation status to the work order processing data;

[0159] The acquisition of the evaluation situation specifically includes:

[0160] If the type of the operation and maintenance work order is a census work order type, then according to the setting position of the detection point, the horizontal distance between the detection point and another previously set detection point is calculated, wherein the detection points are sequentially set on the corresponding optical cables of the optical fiber to be monitored; the horizontal distance between the detection point and another detection point is compared with a preset maximum distance threshold to obtain an evaluation condition of the detection point;

[0161] If the type of the operation and maintenance work order is a fiber core inspection work order type, obtaining the physical property of the detection point as an evaluation condition of the detection point;

[0162] If the type of the operation and maintenance work order is a fault repair work order type, the environmental conditions of the detection point are obtained as the evaluation conditions of the detection point.

[0163] As described above, in this embodiment, for the operation and maintenance work order of the survey work order type, after confirming a new detection point on the optical cable route of the optical fiber to be monitored, it is necessary to calculate the horizontal distance between the detection point and another previously confirmed detection point. The background will automatically obtain the coordinates of the detection point and the other detection point, and calculate their horizontal distance based on the coordinates of the detection point and the other detection point; after obtaining their horizontal distance, the background will compare their horizontal distance with the preset maximum distance threshold to obtain the evaluation of the detection point. Because the horizontal distance is one-to-one between the two detection points, the background only needs to calculate the horizontal distance once and implement two assignments, which can save background computing resources; because in the census, a certain distance limit is met between one detection point and another detection point. If the distance between the two detection points is too large, there will be errors in the optical cable condition obtained based on the detection data of the two detection points. For example, when measuring the loss value of a section of optical cable, the two detection points need to meet the preset distance, and the loss value is only meaningful for reference;

[0164] For the fiber core inspection work order, it is necessary to obtain the physical properties of the inspection point, including whether the total power supply of the inspection point is working normally, whether the interface is working normally at the physical level, and other physical properties; because the physical properties can interfere with the inspection work of the maintenance personnel, abnormal physical properties of the inspection point may lead to incorrect recording of interface access conditions and incorrect detection of basic conditions of the fiber core;

[0165] For fault repair work orders, it is necessary to obtain the environmental conditions of the detection point, including noise interference, terrain interference and other environmental conditions of the detection point. Because if the environmental conditions of the detection point have too much impact on the detection, the detection data will have errors and it will be impossible to determine whether the fault is repaired.

[0166] The step of comparing the horizontal distance between the detection point and another detection point with a preset maximum distance threshold to obtain an evaluation of the detection point specifically includes:

[0167] If the horizontal distance between the detection point and another detection point is lower than a preset maximum distance threshold, the evaluation conditions corresponding to the detection point and another detection point are marked as legal;

[0168] If the horizontal distance between the detection point and another detection point is greater than a preset maximum distance threshold, the evaluation situations corresponding to the detection point and another detection point are marked as illegal.

[0169] It is understandable that if the evaluation status of the detection point is illegal, the maintenance personnel need to reset the detection point so that the horizontal distance between the new detection point and the other detection point is not greater than the maximum distance threshold, and convert the evaluation status corresponding to the new detection point and the other detection point to legal before continuing the detection work; if the evaluation status is legal, the detection work can continue.

[0170] Specifically, the operation and maintenance work order corresponding to the work order processing data is reviewed as follows:

[0171] In combination with the detection parameters and evaluation conditions corresponding to the detection points, the work order processing data is reviewed to obtain the analysis results of the detection points;

[0172] The obtaining of the analysis result corresponding to the detection point specifically includes:

[0173] If the detection task is to survey the routing points of the optical cable corresponding to the optical fiber to be monitored, the overall routing situation of the corresponding optical cable is obtained according to the work order processing data, and the overall routing situation of the corresponding optical cable is used as the analysis result;

[0174] If the detection task is to detect the core usage status of the optical fiber to be monitored or the usage status of the ODF rack corresponding to the optical fiber to be monitored, the core arrangement record of the corresponding optical cable is obtained according to the work order processing data, and the core status arrangement record of the corresponding optical cable is used as the analysis result;

[0175] If the detection task is to troubleshoot the fault of the fiber core to be monitored, the fault processing status of the fiber core to be monitored is obtained according to the work order processing data, and the fault processing status of the optical cable is used as the analysis result.

[0176] In this embodiment, if Figure 2 As shown, the operation and maintenance system also includes:

[0177] The optical path management module 7 is specifically used for:

[0178] Receiving an optical path query instruction, wherein the optical fiber query instruction includes a second named optical fiber;

[0179] In this embodiment, the second named optical fiber is specified by the user. As described above, since the corresponding interface number is matched with the optical fiber to be monitored when the optical fiber to be monitored is connected to the optical time domain reflectometry device, the second named optical fiber can be set by the interface number. Exemplarily, the optical fiber to be monitored with the specific interface number can be set as the second named optical fiber.

[0180] Acquire the corresponding optical fiber to be monitored and the optical path information of the optical fiber to be monitored according to the second named optical fiber;

[0181] In this embodiment, the optical path information may include the organization to which the optical fiber to be monitored belongs, the number of ODF racks, and the number of ODF boxes, etc., so that the specific situation of the optical fiber to be monitored can be understood through the optical path information, and the relationship between the optical fiber to be monitored and other optical fibers in the same organization or ODF rack can also be further obtained through the optical path information.

[0182] Constructing a corresponding optical fiber route according to the acquired optical fiber to be monitored and displaying it on a map;

[0183] The optical path information is displayed correspondingly on the optical fiber routing.

[0184] Specifically, after obtaining the optical fiber route, the corresponding routing node can be determined according to the optical path information of the optical fiber to be monitored, and then the optical fiber route is rendered on the map according to these routing nodes, and the corresponding optical path information is displayed at the corresponding routing node. In this embodiment, the map can be obtained according to existing map software or map generation method.

[0185] By constructing the optical fiber to be monitored on a map, a user can intuitively obtain the optical path information of the optical fiber to be monitored.

[0186] The service management module 8 can be used for:

[0187] receiving a service query instruction, wherein the service query instruction includes a third named optical fiber and / or a service keyword;

[0188] It is understandable that, in this embodiment, the service query instruction may include only the third named optical fiber, or only the service keyword, or may include both the third named optical fiber and the service keyword.

[0189] Specifically, when the service query instruction only includes the third named optical fiber, the service management module 8 obtains the corresponding optical fiber to be monitored and all service information associated with the optical fiber to be monitored according to the third named optical fiber.

[0190] When the service query instruction only includes the service keyword, the service management module 8 obtains all service information including the service keyword according to the service keyword.

[0191] When the business query instruction contains the third named optical fiber and the business keyword, the business management module 8 obtains the corresponding optical fiber to be monitored and all business information associated with the optical fiber to be monitored according to the third named optical fiber, and filters the business information according to the business keyword.

[0192] It can be understood that the business management module 8 is mainly used to obtain the corresponding business information for display according to the business query instructions, so as to effectively realize the management of the business information; in this embodiment, the business information may include the operation business of the optical fiber, and may also include the processing business of the operation and maintenance work order.

[0193] A hidden danger management module 9, wherein the hidden danger management module 9 can be specifically used to generate corresponding hidden danger information according to the operation and maintenance data or hidden danger update instruction;

[0194] In this embodiment, the operation and maintenance data may be analyzed to obtain possible hidden dangers near the optical fiber route of the optical cable to be monitored, such as construction site, traffic overload, etc., or by conducting a site survey, the site survey situation may be entered into specific hidden danger information through a hidden danger update instruction, such as missing optical cable manhole cover, etc.;

[0195] Among them, by analyzing the operation and maintenance data, specifically, a hidden danger analysis model or an external failure analysis model can be constructed through machine learning to analyze the operation and maintenance data to obtain the hidden danger information.

[0196] By entering the hidden danger information, it is convenient to manage the hidden dangers of the optical fiber to be monitored. At the same time, when the optical fiber to be monitored fails, the specific cause of the failure of the optical fiber to be monitored can be determined in combination with the corresponding hidden danger information.

[0197] The hidden danger management module 9 can also be used to obtain corresponding hidden danger information and hidden danger location according to the hidden danger query instruction, confirm the hidden danger location on the map and display the hidden danger information. After querying the hidden danger, the hidden danger information and the corresponding hidden danger location are displayed on the map, so that the location of the fault on the corresponding optical fiber to be monitored can be intuitively obtained, which is convenient for fault inspection and repair.

[0198] The optical fiber quality management module 10 can be specifically used to obtain the loss condition of the corresponding optical fiber to be monitored according to the operation and maintenance data.

[0199] Specifically, in this embodiment, the loss condition of the optical fiber to be monitored can be obtained based on the operation and maintenance data. By setting standard loss data based on the operation and maintenance data, the real-time operation and maintenance data is compared with the standard loss data to obtain the data deviation average value; the loss condition of the optical fiber to be monitored is judged based on the data deviation value.

[0200] Exemplarily, if the data deviation average value exceeds the first data deviation threshold value and does not exceed the second data deviation threshold value, the loss condition of the optical fiber to be monitored can be determined as slight loss; if the data deviation average value exceeds the second data deviation threshold value and does not exceed the third data deviation threshold value, the loss condition of the optical fiber to be monitored can be determined as medium loss; if the data deviation average value exceeds the third data deviation threshold value, the loss condition of the optical fiber to be monitored can be determined as severe loss. The first data deviation threshold value, the second data deviation threshold value and the third data deviation threshold value are set according to the average loss condition of the operation and maintenance data.

[0201] As described above, in a specific implementation of the present embodiment, the optical fiber quality management module 10 can obtain the loss condition of the optical fiber to be monitored through the real-time waveform curve, and by comparing the real-time waveform curve with the reference waveform curve, judge the loss condition of the optical fiber to be monitored according to the deviation between the real-time waveform curve and the reference waveform curve.

[0202] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the present invention shall be included in the protection scope of the claims of the present invention.
