[0002] At present, with the construction of all-optical networks in the field of optical communications, optical cable resources are becoming increasingly large. However, optical cables are "dumb resources" that are imperceptible and cannot be finely managed, becoming a bottleneck for operators' digitalization and self-intelligence.

[0003] The opening of a service by an operator needs to go through multiple jump nodes, including ODF, trunk optical exchange, campus optical exchange, corridor box, etc. During the construction and operation process, due to service cutover and resource adjustment, although there are fiber jumper work orders, due to the uneven sense of responsibility of personnel, the jumper fibers may only be pulled out at both ends of the service starting point, while the optical exchange through which the jumper passes in the middle is not pulled out. Over time, due to factors such as the replacement of maintenance personnel and the lack of testing tools and methods for whether the termination is occupied, no one dares to easily unplug the optical fiber that is not actually used, resulting in the discrepancy between the optical exchange termination resource system data and the actual situation on site.

[0004] At the same time, after the service is opened, due to various reasons, there is actually a completed end in the light exchange, but the resource system is not updated to show that it is idle.

Moreover, the term "comprise" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Example:

[0060] like Figure 1 As shown, in the first aspect, an embodiment of the present invention provides an optical fiber use status detection device, comprising: an optical signal detector, an optical signal detector fixing device, an arc optical fiber coupler, an optical fiber bending radius tester, an optical fiber coupler sliding groove and a rebound slide, wherein the optical signal detector is arranged in the optical signal detector fixing device, the arc optical fiber coupler is arranged on the optical fiber coupler sliding groove and is slidably connected with the optical fiber coupler sliding groove, the optical fiber bending radius tester is arranged at the front end of the optical fiber coupler sliding groove and is located at the center point of the optical signal detector fixing device, the rebound slide is arranged in conjunction with the optical signal detector fixing device and is used to adjust the radius of the arc optical fiber coupler; the optical signal detector fixing device is located at the front end of the arc optical fiber coupler. The optical fiber coupler sliding groove is located on the central axis of the detection device, the arc optical fiber coupler is placed on the optical fiber coupler sliding groove and is connected to each other and can slide forward and backward; the optical fiber bending radius tester is fixed at the front of the sliding groove and is located at the center point of the optical signal detection fixing device; the rebound slide is located at the middle and front position of the detection device and is close to the optical signal detector fixing device.

[0061] The optical fiber to be tested is placed in the groove on the surface of the optical fiber coupler; the coupler is arc-shaped and has adjustable size. When not tested, the radius is the largest. When tested, the radius gradually decreases and becomes elliptical, which is used to meet the test of different optical fibers. Different types of optical fibers or optical fibers with different wavelengths have different bending characteristics, and the signal intensity projected when they are bent is also different; that is, under the same bending radius, the macrobending signal results detected by the detector with the same sensitivity are different. Generally speaking, the longer the wavelength of the optical signal, the higher the sensitivity to bending. For example, 1490nm is more sensitive to bending than 1310nm wavelength, and the macrobending signal projected by the same bending radius of 1490 is larger. Among the commonly used optical fibers, the bend attenuation insensitive single-mode optical fiber used in the G.657 access network is less sensitive to bending than other optical fibers, and the bending radius of the optical fiber can reach 5-10nm. Therefore, in order to detect the use status of the optical fiber, different bending radii should be adjusted for different optical fibers.

[0062] The fiber coupler is pushed and pulled upward along the fiber coupler sliding groove to achieve the fitting of the coupler and the optical signal detector; the fiber bending radius threshold is set to protect the fiber from increased loss or permanent damage caused by excessive bending. The optical fiber is made of glass. When the bending radius is less than a certain value, the insertion loss introduced by the test will increase, which will affect the communication quality of the optical fiber in use. In addition, the optical fiber is brittle. Unrestricted bending of the optical fiber without signal will cause permanent damage to the optical fiber. The slide with rebound (rebound slide) applies force to the optical fiber coupler under the external force of the controller to squeeze the optical fiber coupler. At this time, the shape and radius of the optical fiber coupler become smaller. The optical signal detector fixture is located at the front head position of the overall detection device. Multiple optical signal detectors are embedded in the optical signal detector fixture. The optical signal detector obtains the macrobending signal transmitted when the optical fiber is in a bent state, which is used to detect the use status of the optical fiber. The optical fiber radius tester is used to test the radius of the optical fiber in a bent state. Since the optical fiber is placed in the groove of the optical fiber coupler, the bending radius of the optical fiber changes with the size of the optical fiber coupler. Therefore, the bending radius of the optical fiber can be tested. When the test result reaches the preset value, the test is stopped and the slide with rebound is triggered to return to the initial position.

[0063] This device can adjust the bending diameter of the optical fiber to adapt to optical fibers of different sizes and characteristics and increase the detection range; a bending radius testing device is set so that the bending degree can be tested in real time; a bending radius threshold can be set according to different optical fibers to prevent permanent damage to the optical fiber caused by excessive bending and increase the protection mechanism; a rebound recovery device is set after the detection is stopped to prevent the bending time from lasting too long and affecting the communication quality, thereby improving the safety of detection.

[0064] like Figure 2As shown, an embodiment of the present invention provides an optical fiber usage status detection system, including a camera, an AI recognition module, a macrobend signal test module, an optical fiber radius test module, an optical fiber in-use status judgment module and a control host, wherein:

[0065] A camera is used to obtain image data of the panel at the optical intersection to be measured;

[0066] AI recognition module is used to read the image data of the optical cross-connection field panel, determine the idle and occupied ends according to whether there is a terminated optical fiber inserted in the panel, and output the judgment result to the control host;

[0067] A macrobending signal testing module is used to obtain and output the macrobending signal transmitted when the optical fiber is in a bending state to the optical fiber in-use state judgment module;

[0068] The optical fiber radius test module is used to obtain and output the radius of the optical fiber in a bending state to the optical fiber in-use state judgment module;

[0069] The optical fiber in-use status judgment module is used to compare and analyze the macrobending signal transmitted when the optical fiber is in a bent state, the radius of the optical fiber in a bent state, and the preset parameters, and output the status judgment result to the control host; according to the data collected by the macrobending signal test module and the optical fiber bending radius tester, combined with the preset parameters (bending radius threshold value, macrobending signal parameters), the judgment is made. When the bending radius reaches the threshold value (such as 5mm) or the macrobending signal is detected to be greater than 0, as long as one of the conditions is met, the judgment result is output. The specific judgment analysis rules are shown in Table 1.

[0070] Table 1

[0071] Bending radius test data Macrobend signal test data Conclusion on the status of optical fiber in use The preset threshold is not reached With data There is a signal Reaching the preset threshold With data There is a signal Reaching the preset threshold No data No signal

[0072] The control host is used to receive and analyze the data output by the AI ​​recognition module and the fiber in-use status judgment module. The control host mainly controls the overall operation of the device, such as controlling the fiber radius test module and the macrobend signal test module to start working, pushing the rebound slide to squeeze the arc fiber coupler; when the preset value is reached, the radius test module and the macrobend signal test module are controlled to stop working, and the rebound slide is returned to the initial position.

[0073] The functions of the control host include storage, analysis and control of the linkage of multiple modules, calling and storing the system panel occupancy information of the optical cross to be tested; analyzing and comparing the optical cross occupancy identified by the on-site AI and the system panel occupancy information, finding inconsistent terminations, identifying the optical fiber to be tested, and marking them; controlling the working state of the optical fiber in-use status judgment module: start\disable. When the radius reaches the threshold or a macrobend signal is detected, stop working and control the slider to return to the initial state. Associate the output results of the optical fiber in-use status judgment module with the optical fiber to be tested.

[0074] Based on the second aspect, further, the optical fiber usage status detection system also includes a network connection module for connecting with a resource system to obtain and output system panel occupancy information of the optical cross-connect to be tested to the control host.

[0075] like Figure 4 As shown, in a third aspect, an embodiment of the present invention provides a method for detecting the use status of an optical fiber, comprising the following steps:

[0076] S1. Obtain and set the bending radius threshold according to the optical fiber model;

[0077] S2, acquiring and outputting a macrobending signal transmitted when the optical fiber is in a bending state to an optical fiber in-use state judgment module;

[0078] S3, obtaining and outputting the radius of the optical fiber in a bending state to the optical fiber in-use state judgment module;

[0079] S4. Perform comparison and analysis based on the macrobending signal transmitted when the optical fiber is in a bent state, the radius of the optical fiber in a bent state, and preset parameters, and output the state judgment result to the control host.

[0080] This method is implemented based on the optical fiber usage status detection device described in the first aspect and the optical fiber usage status detection system described in the second aspect. The system panel occupancy information of the optical cross to be tested is called and stored; the optical cross occupancy identified by the on-site AI and the system panel occupancy information are analyzed and compared to find inconsistent ends, identify the optical fiber to be tested, and mark them; control the working state of the optical fiber usage status judgment module: start\disable. When the radius reaches the threshold or the macrobend signal is tested, stop working and control the slide to return to the initial state; associate the result output by the optical fiber usage status judgment module with the optical fiber to be tested to complete the optical fiber usage status detection. The present invention introduces the AI ​​function to scan and identify the on-site occupancy of the optical cross, which reduces manual operations and improves detection efficiency.

[0081] Based on the third aspect, further, the optical fiber usage status detection method further includes the following steps:

[0082] Obtain image data of the panel at the light intersection site to be measured;

[0083] Read the image data of the optical cross-connection field panel, determine the idle and occupied ends according to whether there is a terminated optical fiber inserted in the panel, and output the judgment result to the control host.

[0084] like Figure 5 As shown, in a fourth aspect, an embodiment of the present invention provides a resource system correction method, comprising the following steps:

[0085] A1. Connect the optical fiber usage status detection device and the optical fiber usage status detection system to the corresponding resource system server;

[0086] A2. Retrieve the system panel occupancy information of target detection light intersection;

[0087] A3. Obtain the image data of the panel at the scene of the light intersection to be measured;

[0088] A4. Identify and analyze the image data of the panel at the optical exchange site to be measured, and judge the idle and occupied ends according to whether there is a terminated optical fiber inserted on the panel, so as to determine the occupancy information of the terminated ends at the optical exchange site to be measured;

[0089] A5. Compare the occupancy information of the optical cross-connection site to be tested with the occupancy information of the system panel, generate and mark the inconsistent ends according to the comparison result, and detect the target optical fiber to be tested; the method rules for detecting and determining the target optical fiber to be tested are shown in Table 2.

[0090] Table 2

[0091] Is the site occupied? Is the resource system occupied? Whether it is used as the target fiber to be tested yes no yes no yes no

[0092] A6. Test the target optical fiber to be tested and generate test results;

[0093] Furthermore, it includes: using an optical signal detector to collect macrobending signals, and if the macrobending signal is greater than 0, it indicates that the use status of the optical fiber is in use.

[0094] Furthermore, it also includes: using an optical fiber bending radius tester to test the optical fiber bending radius. If the optical fiber bending radius reaches a preset threshold value, and no macrobending signal is detected at this time, it means that no signal passes through the optical fiber, and the optical fiber is identified as a pending optical fiber, and the pending optical fiber is verified. The verification method can be verified through multiple tests or through other means (such as querying and verifying the work order system).

[0095] A7. Compare the test results with the occupancy information of the optical exchange site to be tested and the occupancy information of the system panel to obtain the test comparison results;

[0096] A8. Generate resource correction processing suggestion information based on the test comparison results and preset values; the above preset values ​​include whether the site is occupied, whether the resource system is occupied, whether it is the target fiber to be tested, whether there is a signal in the field test, and corresponding processing suggestions, etc., as shown in Table 3.

[0097] Table 3

[0098]

[0099] A9. Send the test results and resource correction processing suggestion information to the resource system.

[0100] This resource system correction method is implemented based on the optical fiber usage status detection device described in the first aspect and the optical fiber usage status detection system described in the second aspect. The tester connects the correction device (the correction device consists of the optical fiber usage status detection device and the optical fiber usage status detection system) to the operator's resource system server via WiFi, Bluetooth, and 4\5G network; retrieves the system panel occupancy information of the target detection optical cross-connection; uses the camera function of the detection device to take a photo of the on-site optical cross-connection panel; uses the built-in AI function to identify the on-site terminal occupancy of the optical cross-connection to be tested, and compares it with the resource system panel occupancy information, identifies inconsistent terminals (which can be manually corrected), and detects the target optical fiber to be tested.

[0101] Common situations where optical cross-connection occupancy is inconsistent with resource occupancy include: (1) The optical cross-connection site shows no occupancy, but the resource system shows occupancy. (2) The optical cross-connection site shows occupancy, but the resource system shows no occupancy. This usually represents two situations: one is that there is actually a service, but the resource system has not been updated in time; the other is that there is actually no service, but the terminated fiber on the optical cross-connection has not been unplugged. For optical fibers that actually have services, since a bending radius threshold is set, when the bending radius threshold is reached, no macrobend signal is detected. This does not mean that the optical fiber has no services. In this case, the bending radius threshold can be reduced for retesting, or the operator's work order system can be used for confirmation. Optical fibers that do not actually have services include PON and non-PON services. Non-PON optical fibers can directly correct the resource system data. However, since PON services use broadcast mode for downlink, the pigtails under the same PON port will receive macrobend signals even if there is no service in use. Therefore, for the pigtails with one end connected to the splitter, it is recommended to verify with a PON optical power meter or PON network management system before correction.

[0102] like Figure 3 As shown, the target optical fiber to be tested is tested by the detection device: the optical signal detector is used to collect macrobend signals. If the macrobend signal is greater than 0, it means that the optical fiber is in use, that is, there is a business optical fiber; when the bending radius of the detection device reaches the threshold value, the macrobend signal is still not detected, which means that there is no signal passing through the optical fiber, and it is a pending optical fiber. According to the test results, the on-site occupancy and resource system occupancy information are compared, and corrective processing suggestions are issued for the resources according to the preset values. The test results and corrective processing suggestions are returned to the resource system; adding resources and deleting resources do not require further operation; for the optical fiber to be unplugged, the data of this test bureau is retained and recorded. If there is no data for multiple consecutive tests, the verification process is started, and the operator can confirm whether to unplug the optical fiber in conjunction with the work order system. After receiving the feedback information from the correction device, the resource system manager completes the approval and realizes the resource correction.

[0103] The present invention introduces AI function to scan and identify the occupancy of optical exchange site, thus reducing manual operation and improving detection efficiency; by connecting to the network, the occupancy of optical exchange is compared with the resource system, thereby improving the efficiency of dumb resource cleaning and management; according to the resource system information, the on-site occupancy information and whether there is a signal, the three data are analyzed to provide methods and suggestions for resource correction, which is feasible.
