[0038] Further, the operation and maintenance system further comprises an optical fiber quality management module.

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

[0040] According to the operation and maintenance data, a loss condition of the to-be-monitored optical fiber is acquired.

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

[0042] The fault type of the to-be-monitored optical fiber is judged according to a front-end waveform image and a tail-end waveform image of the real-time waveform curve, wherein the front-end waveform image and the tail-end waveform image are obtained by dividing the real-time waveform curve according to preset limits.

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

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

[0045] If there is no first Fresnel reflection peak in the tail-end waveform image, it is determined that the fault type of the to-be-monitored optical fiber is a serious damage or a breakage of the to-be-monitored optical fiber.

[0046] The judging of the fault type of the to-be-monitored optical fiber according to the front-end waveform image and the tail-end waveform image of the real-time waveform curve can more accurately determine the fault type of the to-be-monitored optical fiber, provide a more detailed problem positioning for subsequent processing of the fault, reduce inefficient investigation by manpower, and improve the efficiency of optical fiber fault repair work.

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

[0048] If there is a loss waveform with a drop exceeding a preset threshold in the middle section waveform image, it is determined that there is damage or poor fusion at a position corresponding to the loss waveform.

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

[0050] The middle section waveform image can reflect the loss of the to-be-monitored optical fiber. If the loss waveform with a drop exceeding a preset threshold appears, it can be determined that there is damage or poor fusion of the optical fiber at the position corresponding to the loss waveform. According to the above determination, a method for locating the damage or poor fusion of the optical fiber is provided for troubleshooting the access problem, which can process the problem in advance before formal detection and operation, and ensure the smooth progress of the formal detection and operation.

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

[0052] If the second Fresnel reflection peak exists in the middle section waveform image, it is determined that there is an optical fiber splicing at the position corresponding to the second Fresnel reflection peak. The middle section waveform image can also reflect the splicing of the to-be-monitored optical fiber. If the second Fresnel reflection peak exists in the middle section waveform image, it can be determined that there is an optical fiber splicing at the position corresponding to the second Fresnel reflection peak. According to the above determination, a method for locating the splicing is provided for troubleshooting the access problem, which can record the situation in advance before formal detection and operation, and ensure that the situation of the to-be-monitored optical fiber is clearly predicted during the formal detection and operation.

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

[0054] If the first Fresnel reflection peak exists in the end waveform image, and the end of the first Fresnel reflection peak is connected to a secondary wave peak, it is determined that the to-be-monitored optical fiber 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 end waveform image can also reflect the termination of the to-be-monitored optical fiber. According to the above determination, a method for locating the termination of the optical fiber is provided for troubleshooting the access problem, which can record the situation of the optical fiber in advance before formal detection and operation, and ensure the smooth progress of the formal detection and operation.

[0057] Further, the work order auditing module is also used to obtain the evaluation situation of the detection point, and add the evaluation situation to the work order processing data;

[0058] The evaluation situation is obtained, specifically including:

[0059] If the type of the operation and maintenance work order is a general survey work order type, then according to the set position of the detection point, the horizontal distance between the detection point and another detection point that is previously set is calculated, wherein the detection points are sequentially set on the corresponding optical cable of the optical fiber to be monitored; the horizontal distance between the detection point and the other detection point is compared with a preset maximum distance threshold to obtain the evaluation situation of the detection point; if the type of the operation and maintenance work order is a fiber core checking work order type, then the physical property situation of the detection point is obtained as the evaluation situation of the detection point; if the type of the operation and maintenance work order is a fault repair work order type, then the environment situation of the detection point is obtained as the evaluation situation of the detection point.

[0060] In the general survey work order type, a certain distance limit is met between one detection point and another detection point. If the distance between two detection points is too large, the situation of the optical fiber to be monitored obtained according to the detection data of the two detection points will have errors, such as measuring the loss value of a section of optical fiber. The two detection points need to meet a preset distance, and the loss value has reference significance. In the fiber core checking work order type, the physical property situation of the detection point will affect the accuracy of the fiber core checking. The physical properties of the detection point include whether the power supply of the detection point is normal, whether the interface is normal, and the like. These physical properties will affect the fiber core checking and need to be taken as the evaluation situation to assist the auditing work. In the fault repair work order type, the environment situation of the detection point will affect the judgment of the detection point on the fault repair, such as large noise interference and rationality of the detection position, which will affect the analysis of the fault repair and need to be taken as the evaluation situation to assist the auditing work. According to the setting situation of the detection point, an auxiliary index is provided for the optical cable operation and maintenance work order auditing work to evaluate the setting of the detection point, which can add a judgment dimension to the auditing work and reduce the misjudgment rate of the auditing.

[0061] Further, the comparison of the horizontal distance between the detection point and the other detection point with the preset maximum distance threshold to obtain the evaluation situation of the detection point specifically includes:

[0062] If the horizontal distance between the detection point and the other detection point is lower than the preset maximum distance threshold, then the corresponding evaluation situations of the detection point and the other detection point are both marked as legal;

[0063] If the horizontal distance between the detection point and the other detection point is greater than the preset maximum distance threshold, then the corresponding evaluation situations of the detection point and the other detection point are both marked as illegal.

[0064] Through the judgment between the distances, the legal detection point and the illegal detection point are set, and the evaluation situation of the route survey work order is obtained, which can provide a reminder for the detection work and an auditing material for the auditing work.

[0065] Further, the work order processing data is used to audit the operation and maintenance work order, specifically:

[0066] The work order processing data is audited in combination with the detection parameters and evaluation conditions of the detection points to obtain analysis results of the detection points.

[0067] The analysis results of the detection points are obtained, specifically including:

[0068] If the detection task is to survey the routing points of the corresponding optical cable of the to-be-monitored optical fiber, the overall routing condition of the corresponding optical cable is obtained from the work order processing data, and the overall routing condition of the corresponding optical cable is taken as the analysis result.

[0069] If the detection task is to detect the core use state of the to-be-monitored optical fiber or the use condition of the ODF frame corresponding to the to-be-monitored optical fiber, the core arrangement record condition of the corresponding optical cable is obtained from the work order processing data, and the core arrangement record condition of the corresponding optical cable is taken as the analysis result.

[0070] If the detection task is to investigate the fault condition of the to-be-monitored optical fiber, the fault processing state condition of the to-be-monitored optical fiber is obtained from the work order processing data, and the fault processing state condition of the optical cable is taken as the analysis result.

[0071] Different detection tasks require different feedbacks. For the detection task of surveying the routing points of the corresponding optical cable of the to-be-monitored optical fiber, it is necessary to analyze whether the operation conditions of a plurality of detection points of the corresponding optical cable are normal, and the overall routing condition of the optical cable is fed back. For the detection task of detecting the core use state of the to-be-monitored optical fiber or the use condition of the ODF frame corresponding to the corresponding optical cable, it is necessary to count the core state arrangement condition of the corresponding optical cable in the range, and pay attention to the record condition of the added or deleted optical fiber, and feed back the specific use condition of the optical fiber in the range. For the detection task of investigating the fault condition of the to-be-monitored optical fiber, it is necessary to analyze the detection data of the detection points near the fault to determine the specific fault type and positioning, and feed back the fault state condition of the to-be-monitored optical fiber. Different types of analysis results are necessary standards for auditing the optical cable operation and maintenance work order and accepting the entire detection work, and the complex steps of optical cable operation and maintenance are optimized to provide accurate and detailed operation and maintenance information for optical cable operation and maintenance.

[0072] Compared with the prior art, the present application has the following advantages:

[0073] The application polls and collects the operation and maintenance data of the to-be-monitored optical fibers through the data acquisition module, and then generates a real-time waveform curve corresponding to the to-be-monitored optical fiber according to the operation and maintenance data, and analyzes and judges the fault type of the to-be-monitored optical fiber according to the real-time waveform curve. A large amount of operation and maintenance data is sorted to obtain the real-time waveform curve, which can be used to intuitively and quickly judge the fault type of the to-be-monitored optical fiber by using the characteristics of the curve image. The work order construction module uses the fault type of the to-be-monitored optical fiber, and uses the routing situation and the core use state of the to-be-monitored optical fiber to correspondingly construct a plurality of different types of operation and maintenance work orders, so that the staff can correspondingly process the operation and maintenance work orders of different types, and improve the efficiency of processing the operation and maintenance work orders. In addition, during the processing of the work order, a detection point is set in the area range of the to-be-monitored optical fiber, and the operation and maintenance work order is audited through the detection data and the corresponding position information of the detection point. Through the specific detection data, the auditing of the operation and maintenance work order can be more accurately realized, and the reliability of the operation and maintenance system is improved.

[0077] The drawings of the application are only used for illustrative description, and cannot be understood as a limitation of the application. In order to better illustrate the following embodiments, some components in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0078] Embodiment 1

[0079] As shown in Figure 1 , the present embodiment provides an optical cable operation and maintenance system, which can specifically include:

[0080] The data acquisition module 1 is used for polling and monitoring a plurality of to-be-monitored optical fibers in a polling order, and collecting operation and maintenance data in the to-be-monitored optical fibers.

[0081] It can be understood that the polling order is a basic resource scheduling and resource allocation mechanism, which ensures the fairness and stability of the entire workflow by sequentially accessing or processing a plurality of objects according to certain rules. In the embodiment, the polling order is obtained according to the plurality of to-be-monitored optical fibers, and each to-be-monitored optical fiber is provided with a fair polling opportunity, so that each to-be-monitored optical fiber can be monitored, and the plurality of optical fibers are maintained in all directions.

[0082] The polling order can be obtained by specifically comprising:

[0083] First, the interface number corresponding to each to-be-monitored optical fiber is obtained.

[0084] It can be understood that in the embodiment, the optical time domain reflection device is used for monitoring. The interface number is an identifier of each interface on the optical time domain reflection device. The optical time domain reflection device can be connected to the plurality of to-be-monitored optical fibers, and the to-be-monitored optical fibers are monitored. For the plurality of to-be-monitored optical fibers connected to the same optical time domain reflection device, in order to facilitate distinction, the interface number on the optical time domain reflection device is used to correspond to the to-be-monitored optical fiber one by one, so as to quickly locate one of the to-be-monitored optical fibers. It can be understood that before the to-be-monitored optical fiber is connected to the optical time domain reflection device for monitoring, the to-be-monitored optical fiber and the interface number on the optical time domain reflection device need to be bound and recorded in advance, so as to ensure correct arrangement of the polling order and one-to-one correspondence of the monitoring data generated by each to-be-monitored optical fiber during subsequent uploading.

[0085] After obtaining the corresponding interface number, the interface number is obtained according to a preset interface arrangement rule to obtain the polling order.

[0086] It can be understood that in the embodiment, the one-to-one relationship between the interface number and the to-be-monitored optical fiber needs to be recorded in advance, and the interface arrangement rule needs to be set in advance; the interface number of the to-be-monitored optical fiber is obtained, the interface numbers are sorted according to the interface arrangement rule to obtain an interface number sorting table, and the polling order that can be executed is obtained by processing the interface number sorting table.

[0087] In the embodiment, the polling monitoring specifically comprises:

[0088] The monitoring time interval and the monitoring pulse width of each to-be-monitored optical fiber are set.

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

[0090] It can be understood that the monitoring time interval is the time length required for one monitoring work of the to-be-monitored optical fiber. For the monitoring of the to-be-monitored optical fiber, continuous data needs to be obtained through continuous monitoring to obtain the data change in the to-be-monitored optical fiber. The monitoring time interval is set according to the operation and maintenance needs. It can be understood that the monitoring time interval is too short, which will affect the integrity of the recovered optical fiber data; the monitoring time interval should not be too long, which will affect the efficiency of the entire polling monitoring.

[0091] In the embodiment, the monitoring pulse width of each to-be-monitored optical fiber also needs to be set. It can be understood that the time length of the optical pulse of the optical time domain reflection device can also be converted into the space length of the pulse on the optical fiber. According to the basic properties of each to-be-monitored optical fiber, the monitoring pulse width of the to-be-monitored optical fiber is adaptively set, which can ensure the stability and reliability of the monitoring work, and can improve the monitoring accuracy of each to-be-monitored optical fiber and provide the quality of the monitoring work.

[0092] The curve generation module 2 is configured to generate a real-time waveform curve corresponding to the to-be-monitored optical fiber according to the operation and maintenance data.

[0093] It can be understood that the real-time waveform curve reflects the real-time link state and performance of the to-be-monitored optical fiber in the monitoring. The real-time curve is generated according to the operation and maintenance data received in real time through the polling monitoring, which can help the operation and maintenance personnel to observe the real-time running condition of the to-be-monitored optical fiber.

[0094] In the embodiment, the data acquisition module 1 is further configured to:

[0095] obtain a roll call monitoring instruction, the roll call monitoring instruction contains a first roll call optical fiber, suspend the polling monitoring according to the roll call monitoring instruction, and perform roll call monitoring on the first roll call optical fiber, and after completing the roll call monitoring, continue the polling monitoring;

[0096] The curve generation module is further configured to generate a roll call waveform curve corresponding to the first roll call optical fiber according to roll call data of the first roll call optical fiber.

[0097] In the embodiment, the point monitoring indicates monitoring of a specified optical fiber, which is an optical fiber that needs to be immediately queried for real-time operation. It can be understood that the polling monitoring is a continuous process, as described above, which monitors the to-be-monitored optical fibers in a preset polling order, and each of the optical fibers has a certain monitoring time interval. When a to-be-monitored optical fiber is polled, a long time interval may be present before the to-be-monitored optical fiber is presented again. In some emergency situations that require sudden monitoring of a to-be-monitored optical fiber, the to-be-monitored optical fiber cannot be monitored in time by polling, and the point monitoring on the to-be-monitored optical fiber cannot be performed (because polling is switched to the next optical fiber). Therefore, the function of jumping to monitor a specific to-be-monitored optical fiber is needed. It can be understood that the point monitoring instruction includes basic information of a first point monitoring optical fiber specified by an operator, and the background can locate the interface number connected to the first point monitoring optical fiber according to the basic information and perform point monitoring on the first point monitoring optical fiber. It can be understood that before the point monitoring starts, the polling monitoring needs to be paused to prevent conflict between the two types of monitoring.

[0098] It can be understood that before the polling monitoring is paused, the polling progress of the polling monitoring needs to be maintained so that the polling monitoring can continue to run from the last interrupted position when the polling monitoring is continued. Therefore, the current position in the polling order needs to be recorded so that the polling monitoring can continue to read from the current position in the polling order next time.

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

[0100] It can be understood that the historical waveform curve reflects the historical link state and performance of the to-be-monitored optical fiber in monitoring. The historical waveform curve is generated by selection from the real-time waveform curve, specifically as follows.

[0101] The real-time waveform curve is monitored, and when the background detects that the real-time waveform curve changes, a historical waveform curve corresponding to the to-be-monitored optical fiber is generated according to the changed real-time waveform curve, and a time point of generating the historical waveform curve is recorded. The historical waveform curve is saved in association with the corresponding time point;

[0102] When the background detects that the real-time curve does not change, the historical curve maintains the original value.

[0103] It can be understood that the historical waveform curve is empty at the beginning of monitoring. As the monitoring continues, the historical waveform curve corresponding to the to-be-monitored optical fiber can be continuously increased. Since the historical waveform curve is obtained according to the change of the real-time waveform curve, the historical waveform curve can reflect the change of the to-be-monitored optical fiber for a period of time. Therefore, the running condition of the to-be-monitored optical fiber at the corresponding time point can be analyzed by obtaining the historical waveform curve at the corresponding time point.

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

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

[0106] It can be understood that the reference waveform curve reflects the link state and performance of the to-be-monitored optical fiber in normal operation in monitoring. The reference waveform curve is generated according to the real-time waveform curve, which can provide an intuitive correct state reference for the operation and maintenance personnel, and provide a reference for the real-time operation condition of the optical fiber.

[0107] In a preferred embodiment, the curve generation module 2 is further used to visually display at least two of the real-time waveform curve, the point-name waveform curve, the historical waveform curve, and the reference waveform curve.

[0108] It can be understood that the real-time waveform curve, the point-name waveform curve, the historical waveform curve, and the reference waveform curve can be displayed singly, in pairs, or in three combinations. Single display can reflect the information originally held by the curve. Multiple combinations for display can more intuitively observe the change of the curve. When multiple combinations for display are needed, the corresponding curves can be set in the same coordinate, and displayed after time and scale alignment according to data conditions.

[0109] The fault analysis module 3 is used to determine the fault type of the to-be-monitored optical fiber according to the real-time waveform curve.

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

[0111] According to the front-end waveform image and the end waveform image of the real-time waveform curve, the fault type of the to-be-monitored optical fiber is determined, 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 a front-end waveform image and a rear-end waveform image according to preset boundaries, which respectively correspond to the running state of the front-end and rear-end positions of the to-be-monitored optical fiber. The real-time waveform curve is observed and determined separately, which can quickly locate the position of the fault occurrence and speculate the type of the fault, thereby providing a detailed and orderly method for determining the fault of the to-be-monitored optical fiber.

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

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

[0115] The fault type of the to-be-monitored optical fiber is determined according to the front-end waveform image and the end waveform image of the real-time waveform curve, and the fault type of the to-be-monitored optical fiber is determined according to the front-end waveform image and the end waveform image of the real-time waveform curve.

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

[0117] If there is no first Fresnel reflection peak in the end waveform image, it is determined that the fault type of the to-be-monitored optical fiber is that the to-be-monitored optical fiber is severely damaged or broken.

[0118] In the embodiment, the front-end waveform image does not appear a large range of vibration response, i.e. does not continuously appear several vibration peaks, in the state that the to-be-monitored optical fiber is normally accessed; and a first peak width is not more than a preset normal peak width threshold, preferably, the preset normal peak width threshold is 40 m; if the first peak width is greater than the preset peak width threshold, it indicates that there is a greater loss between the to-be-monitored optical fiber and the optical time domain reflection device, so that the first peak width exceeds the normal peak width threshold, so that the subsequent waveform is relatively stable and abnormal, which affects the judgment of subsequent formal detection and operation; the above fault type can determine that the fault type of the to-be-monitored optical fiber is a poor contact of a starting port; for the problem of poor contact of the starting port, generally, a joint between the to-be-monitored optical fiber and the optical time domain reflection device has a problem, and the problem needs to be repaired.

[0119] The rear-end waveform image has only one obvious Fresnel reflection peak in the state that the to-be-monitored optical fiber is normally accessed, wherein the Fresnel reflection peak is a peak value formed by an intense backscattering light signal due to a refractive index mismatch of some specific points in the to-be-monitored optical fiber. In the embodiment, the Fresnel reflection peak is used to reflect the state of the position of the end connection of the to-be-monitored optical fiber; if the first Fresnel reflection peak does not exist in the end waveform image, it indicates that the to-be-monitored optical fiber is seriously damaged or broken, and the pulse laser cannot continue to propagate to the rear, so that the to-be-monitored optical fiber needs to be tested for a broken point damage, and a seriously damaged or broken point of the to-be-monitored optical fiber is found out.

[0120] Specifically, the method further comprises:

[0121] If the loss waveform with a drop amplitude exceeding a preset threshold exists in the middle section waveform image, it is determined that a position corresponding to the loss waveform has damage or poor fusion.

[0122] The middle section waveform image is a waveform image between the front-end waveform image and the end waveform image. In the embodiment, in the real-time waveform curve of the coordinate system, an area between the front-end waveform image and the end waveform image is acquired, and the real-time waveform curve contained in the area is the middle section waveform image.

[0123] In the embodiment, the middle section waveform image may have multiple waveform dips, but if the dip is within the loss range of the preset threshold, it is normal propagation loss and will not seriously affect the detection and operation; but if there is a loss waveform with a dip exceeding the preset threshold in the middle section waveform image, it means that the position of the loss waveform corresponding to the to-be-monitored optical fiber has a damage or poor fusion problem, and the corresponding position needs to be investigated and repaired.

[0124] The fault analysis module 3 further includes the following steps after judging the fault type of the to-be-monitored optical fiber according to the real-time waveform curve:

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

[0126] In the embodiment, the middle section waveform image may also have another waveform condition, that is, there is a second Fresnel reflection peak in the middle section waveform image, which means that there is a splice in the to-be-monitored optical cable. Fiber splicing 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, find the splicing position, and record the splicing position later. It can be understood that.

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

[0128] If there is the first Fresnel reflection peak in the end section waveform image, and the end of the first Fresnel reflection peak is connected to a secondary wave peak, it is determined that the to-be-monitored optical fiber 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 the embodiment, the end section waveform image may also have another waveform condition, that is, there is the first Fresnel reflection peak in the end section waveform image, and the end of the first Fresnel reflection peak is connected to a secondary wave peak. According to this waveform condition, it can be determined that the to-be-monitored optical fiber has been terminated. It can be understood that the termination of the to-be-monitored optical fiber means that the outdoor test optical fiber is introduced into the machine room and a series of processing and connection operations are performed, so that it can normally communicate with other communication devices; the termination of the to-be-monitored optical fiber can be recorded, and a clear situation of the to-be-monitored optical fiber can be predicted in the subsequent formal detection and operation.

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

[0132] If the real-time waveform curve appears static display, freezing or missing, it is determined that the optical time domain reflection device network is unstable.

[0133] It can be understood that the real-time waveform curve is relatively static in the overall trend, but in fact, the real-time waveform curve is displayed according to the received real-time operation and maintenance data, so when the real-time waveform curve appears static display, freezing or missing, it indicates that the reception of the operation and maintenance data is abnormal, and the network needs to be investigated.

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

[0135] The work order construction module 4 is configured to generate an operation and maintenance work order of a fault repair work order type according to the fault type of the to-be-monitored optical fiber.

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

[0137] Therefore, in the embodiment, the work order construction module 4 is further configured to construct an operation and maintenance work order of a survey work order type according to the route of the to-be-monitored optical fiber, and construct an operation and maintenance work order of a fiber core inventory work order type according to the fiber core use state of the to-be-monitored optical fiber.

[0138] The types of the operation and maintenance work order are specifically as follows:

[0139] Survey work order type:

[0140] It can be understood that an optical cable in use needs to know the route of the optical cable and continuously detect the health of the optical cable, so as to predict possible faults of the optical cable in advance, take measures to deal with the faults in advance, and reduce the loss caused by business interruption as much as possible. Therefore, the optical cable needs to be fully surveyed and detected. Specifically, a route position detection point can be set at a predetermined distance of the optical cable, the detection point is detected to obtain detection data, whether the optical cable passes through the route position detection point and the length distance of the optical cable at the route position detection point are confirmed by observing whether the real-time waveform of the optical fiber has a response.

[0141] Fiber core inventory work order type:

[0142] It can be understood that due to the large number of optical cables in use, in the event of emergency repair of faults or switching of standby cores, it is possible that the optical cable access or exit data is not synchronized in time, and it is necessary to regularly and physically detect and check the service optical cable situation, mark the optical cable that has no service but is always working, update the optical cable database, and provide accurate optical cable layout for operation and maintenance work, which helps better monitoring of optical cables.

[0143] Fault repair work order type:

[0144] It can be understood that if the optical cable cannot work normally, it is suspected to have a fault, and after preliminary judgment of the fault type, further on-site detection is needed to accurately locate and understand the situation of the fault, and a nearby detection point needs to be set in the fault area to accurately investigate the fault and provide accurate optical cable information and reference data for fault handling.

[0145] The work order processing module 5 is configured to obtain a detection task of the optical fiber to be monitored and a region range in which the optical fiber to be monitored is arranged 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 can be understood that different types of operation and maintenance work orders correspond to different detection tasks, and the detection task can specifically include:

[0147] When the type of the operation and maintenance work order is the general survey work order type, the detection task is to survey the routing point of the corresponding optical cable of the optical fiber to be monitored;

[0148] When the type of the optical cable operation and maintenance work order is the core checking work order type, the detection task is to detect the core use state of the corresponding optical cable or the use situation of the ODF frame of the corresponding optical cable;

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

[0150] By constructing a plurality of operation and maintenance work orders corresponding to different types, different detection tasks are set according to different types of operation and maintenance work orders, the detection direction of each work order can be determined, so that the detection personnel can quickly dispatch professional repair personnel to the site for detection after receiving the work order and the corresponding detection task, and the efficiency of receiving and processing the work order is improved. Furthermore, through the detection task, the subsequent audit work can be adjusted, and the detection task is used as the basis for whether to pass the audit, which also improves the efficiency of the audit.

[0151] The work order audit module 6 is configured to audit the operation and maintenance work order according to the work order processing data.

[0152] In the embodiment, the work order processing data is obtained by binding detection data and a corresponding detection point through position information; the detection data is obtained by detecting the detection point according to a detection parameter of the detection point and the detection task; the detection point is set in a region range of a corresponding optical cable of the optical fiber to be monitored according to the detection task, and the detection parameter is set according to the detection point.

[0153] It can be understood that for any optical cable, in the region range thereof, some routing points may be included, which are fixed and unchangeable, and can play a certain identification role in actual operation and maintenance detection, and these routing points can be confirmed as detection points. However, there are also some cases, such as when the position to be detected does not fall on the fixed routing points, the fixed routing points cannot be used to accurately position the position to be detected, and new routing points need to be confirmed as detection points. Therefore, in the embodiment, after the operation and maintenance work order is obtained, the detection points are confirmed according to different requirements of the detection task, so that the maintenance personnel can adaptively confirm fixed and / or unfixed detection points according to the detection task.

[0154] For example, for the operation and maintenance work order of the general survey type, the key positions of the corresponding optical cable of the optical fiber to be monitored as a whole need to be surveyed, and the detection points need to be confirmed at the routing points of the corresponding positions. Preferably, a detection point can be confirmed at the machine room at the starting end of the corresponding optical cable, and then a plurality of detection points can be confirmed in sequence along the optical cable routing.

[0155] For the fiber core checking work order, the use state of the fiber core of the corresponding optical cable or the use situation of the ODF frame of the corresponding optical cable needs to be checked, and the detection points need to be set at places where a large number of optical cables are accessed / transferred, such as machine rooms and optical cable wells.

[0156] For the fault maintenance work order, the fault point of the corresponding optical cable needs to be fault-maintained and investigated, and the detection points need to be set near the fault point to accurately obtain the position of the fault and maintain it.

[0157] In the embodiment, the detection points 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 points. The attribute information of the corresponding optical cable needs to be input in advance before detection, and the attribute information can include the optical cable length, the host selected for detection, the optical cable port, and the general survey direction, etc. The attribute information records the background of the detection work, and facilitates the rapid positioning of the basic situation of the detection work in the auditing work.

[0158] Further, the work order auditing module 6 is further configured to acquire an evaluation condition of the detection point and add the evaluation condition into the work order processing data;

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

[0160] If the type of the operation and maintenance work order is a general survey work order type, the horizontal distance between the detection point and another detection point previously set is calculated according to the set position of the detection point, the detection point is sequentially set on the corresponding cable of the optical fiber to be monitored, the horizontal distance between the detection point and the another detection point is compared with a preset maximum distance threshold, and the evaluation condition of the detection point is acquired;

[0161] If the type of the operation and maintenance work order is a fiber core checking work order type, the physical attribute condition of the detection point is acquired as the 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 environment condition of the detection point is acquired as the evaluation condition of the detection point.

[0163] As described above, in the present embodiment, for the operation and maintenance work order of the general survey work order type, after a new detection point is confirmed on the cable route of the optical fiber to be monitored, the horizontal distance between the detection point and another detection point previously confirmed needs to be calculated. The coordinates of the detection point and the another detection point are automatically acquired by the background, and the horizontal distance between the detection point and the another detection point is calculated according to the coordinates. After the horizontal distance is acquired, the background compares the horizontal distance with a preset maximum distance threshold to acquire the evaluation condition of the detection point. Because the horizontal distance is one-to-one corresponding between two detection points, the background only needs to calculate the horizontal distance once and realizes twice assignment, which can save the background calculation resources. Because in the general survey, a detection point and another detection point satisfy a certain distance limit. If the distance between the two detection points is too large, the cable condition acquired according to the detection data of the two detection points will have errors. For example, when the loss value of a cable is measured, the two detection points need to satisfy the preset distance, and the loss value has reference significance;

[0164] For the fiber core checking work order, the physical attribute condition of the detection point needs to be acquired, including whether the total power supply of the detection point works normally, whether the interface works normally on the physical layer, and other physical attribute conditions. Because the physical attribute condition can interfere with the checking work of the repair personnel, if the physical attribute of the detection point is abnormal, it may cause errors in the interface access condition record and the fiber core basic condition detection;

[0165] For the troubleshooting work order, the environment of the detection point needs to be obtained, including the noise interference, terrain interference and other environment of the detection point, because if the environment of the detection point has too great influence on the detection, the detection data will have errors, and it cannot be determined whether the troubleshooting of the fault is completed.

[0166] The horizontal distance between the detection point and another detection point is compared with a preset maximum distance threshold, and the evaluation situation of the detection point is obtained, specifically including:

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

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

[0169] It can be understood that if the evaluation situation of the detection point is illegal, the maintenance personnel needs to reset the detection point, so that the horizontal distance between the new detection point and another detection point is not greater than the maximum distance threshold, and the evaluation situation corresponding to the new detection point and another detection point is converted to legal, and then the detection work is continued; if the evaluation situation is legal, the detection work can be continued.

[0170] Specifically, the auditing of the operation and maintenance work order according to the work order processing data is specifically:

[0171] The detection parameters and evaluation situation corresponding to the detection point are combined to audit the work order processing data, and the analysis result of the detection point is obtained;

[0172] The analysis result corresponding to the detection point is obtained, specifically including:

[0173] If the detection task is to survey the routing point of the corresponding optical cable of the to-be-monitored optical fiber, 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 taken as the analysis result;

[0174] If the detection task is to detect the core use state of the to-be-monitored optical fiber or the use situation of the ODF frame corresponding to the to-be-monitored optical fiber, the core arrangement record situation of the corresponding optical cable is obtained according to the work order processing data, and the core arrangement record situation of the corresponding optical cable is taken as the analysis result;

[0175] If the detection task is to investigate the fault condition of the to-be-monitored optical fiber, the fault processing state condition of the to-be-monitored optical fiber is acquired according to the work order processing data, and the fault processing state condition of the optical cable is taken as an analysis result.

[0176] In the embodiment, as shown in Figure 2 The operation and maintenance system further includes:

[0177] An optical path management module 7, which is specifically configured to:

[0178] Receive an optical path query instruction, wherein the second named optical fiber is included in the optical path query instruction;

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

[0180] According to the second named optical fiber, the corresponding to-be-monitored optical fiber and the optical path information of the to-be-monitored optical fiber are acquired;

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

[0182] According to the acquired to-be-monitored optical fiber, a corresponding optical fiber route is constructed and displayed on a map;

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

[0184] Specifically, after the optical fiber route is acquired, the corresponding route nodes can be determined according to the optical path information of the to-be-monitored optical fiber, and the optical fiber route can be rendered on the map according to the route nodes, and the optical path information is displayed on the corresponding route nodes. In the embodiment, the map can be acquired according to an existing map software or a map generation method.

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

[0186] A service management module 8, which can be specifically configured to:

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

[0188] It can be understood that in the embodiment, the service query instruction can only contain the third named fiber, only contain the service keyword, or contain both the third named fiber and the service keyword.

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

[0190] When the service query instruction only contains the service keyword, the service management module 8 acquires all service information containing the service keyword according to the service keyword.

[0191] When the service query instruction contains both the third named fiber and the service keyword, the service management module 8 acquires the corresponding to-be-monitored fiber according to the third named fiber and all service information associated with the to-be-monitored fiber, and screens the service information according to the service keyword.

[0192] It can be understood that the service management module 8 is mainly used to acquire corresponding service information according to the service query instruction and display the service information, thereby effectively realizing management of the service information. In the embodiment, the service information can include an operation service of a fiber or a processing service of the operation and maintenance order.

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

[0194] In the embodiment, possible hidden dangers near the fiber route of the to-be-monitored cable, such as construction site construction, traffic overload, etc., can be acquired by analyzing the operation and maintenance data, or specific hidden danger information such as missing cable manhole covers can be recorded by hidden danger update instruction through on-site survey.

[0195] The operation and maintenance data can be analyzed by constructing a hidden danger analysis model or an external damage analysis model through machine learning to acquire the hidden danger information.

[0196] By inputting the hidden danger information, the hidden danger of the to-be-monitored optical fiber can be conveniently managed. Meanwhile, when the to-be-monitored optical fiber fails, the specific failure cause of the to-be-monitored optical fiber can also be determined in combination with the corresponding hidden danger information.

[0197] The hidden danger management module 9 can also be used to acquire corresponding hidden danger information and a hidden danger position according to a hidden danger query instruction, confirm the hidden danger position on a map and display the hidden danger information. By realizing the hidden danger information and the corresponding hidden danger position on the map after querying the hidden danger, the position condition of the failure on the corresponding to-be-monitored optical fiber can be intuitively acquired, and the failure maintenance is facilitated.

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

[0199] Specifically, in the embodiment, the loss condition of the to-be-monitored optical fiber can be acquired according to the operation and maintenance data. By setting standard loss data according to the operation and maintenance data, the real-time operation and maintenance data is compared with the standard loss data to acquire a data deviation average value, and the loss condition of the to-be-monitored optical fiber is judged according to the data deviation value.

[0200] For example, if the data deviation average value exceeds a first data deviation threshold value and does not exceed a second data deviation threshold value, the loss condition of the to-be-monitored optical fiber can be determined as slight loss; if the data deviation average value exceeds the second data deviation threshold value and does not exceed a third data deviation threshold value, the loss condition of the to-be-monitored optical fiber can be determined as moderate loss; and if the data deviation average value exceeds the third data deviation threshold value, the loss condition of the to-be-monitored optical fiber can be determined as serious 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 embodiment, the optical fiber quality management module 10 can acquire the loss condition of the to-be-monitored optical fiber through the real-time waveform curve, compare the real-time waveform curve with the reference waveform curve, judge the loss condition of the to-be-monitored optical fiber according to the deviation between the real-time waveform curve and the reference waveform curve.

[0202] Obviously, the above embodiments of the present application are only examples for clearly illustrating the technical solutions of the present application, and are not intended to limit the specific implementation of the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
