Description

Technical Field

[0001] The present invention relates to the field of optical fibers, and more particularly to a system and method for coordinated control of protection and self-healing of an intelligent optical fiber network. Background Art

[0002] Power communication networks rely primarily on fiber-optic communications, which are crucial for power dispatching, automation, and relay protection. Currently, power communication optical cable networks are large and complex, susceptible to both natural and human factors. Optical cable failures are one of the main factors impacting power communication services. Therefore, strengthening the monitoring and maintenance of optical cables is crucial to ensuring the operation of both the power communication network and the power grid. In recent years, the automation level of power grid construction and power system equipment has continued to increase, leading to rapid development of the power communication network. Management and maintenance have become intelligent, with key communication equipment now supporting remote alarm monitoring and network management. However, the operation and maintenance of power cable networks still relies on manual maintenance and lacks automated O&M technology. This has become a key limitation in O&M efficiency. For example, optical line commissioning and repairs are time-consuming, labor-intensive, and inefficient. Fiber cable outages are slow to locate, impacting repair efficiency. Fiber core testing is time-consuming and inconvenient for data analysis.

[0003] Existing intelligent optical fiber distribution systems (smart ODFs) consist of a master station system and a station-side device. However, data management, including fiber routing, fiber core resources, and service information, as well as patching, inspection, and testing, is performed manually at the station-side. How to enable the smart ODF to receive remote commands and automatically perform patching, inspection, and testing of designated ports, among other tasks, remains a pressing technical challenge in this field.

[0009] It is beneficial to achieve high-precision and flexible positioning of the manipulator in the X-axis, Y-axis and Z-axis through multi-level telescopic freedom, avoiding collision with the distribution board during movement; the freedom of the manipulator is limited to the plane parallel to the distribution board by the first position, the freedom of the manipulator when moving with the optical fiber after clamping the optical fiber is limited by the second position, and the freedom of the manipulator when clamping the first terminal or the second terminal is limited by the third position, so that the manipulator is in full contact with the optical fiber, the first terminal and the second terminal without colliding with other components on the distribution board.

[0011] It is beneficial to expand the contact area of the manipulator when clamping the optical fiber through the V-shaped elastic mechanism, and to prevent the optical fiber from getting stuck when being moved out of the storage area by the manipulator through the release assist mechanism. The angle change of the manipulator when clamping and releasing the optical fiber can adapt to the different fixing methods of the optical fiber in the storage area and the use area.

[0012] Furthermore, the fiber optic ports arranged in a matrix on the distribution board are divided into an occupied area and a recovery area. The number of fiber optic ports in the occupied area is more than that in the recovery area. The recovery area and the occupied area are distributed on the left and right. The working optical fibers and spare optical fibers of the communication equipment are connected to the fiber optic ports in the occupied area. The spare optical fiber connection lines are connected to the optical fiber ports on the upper layer of the occupied optical fiber connection lines. The first terminal and the second terminal of the spare optical fiber connection line are connected to two adjacent optical fiber ports.

[0013] It is beneficial to divide the distribution board into an occupied area and a recovery area, so that if any fiber optic port in the occupied area fails, it can be connected to the recovery area; by connecting the spare optical fiber and the used optical fiber to the fiber optic port in the occupied area at the same time, the optical fiber line connected to each fiber optic port can be switched to the spare optical fiber when a failure occurs; the first terminal and the second terminal of the spare optical fiber connecting line are connected to the two adjacent fiber optic ports, which facilitates the robot to achieve the shortest distance plugging and unplugging.

[0014] Furthermore, the storage area includes a plurality of vertical areas arranged left and right divided by a plurality of vertical partitions, the first terminal and the second terminal of each spare optical fiber connection line are connected to two adjacent optical fiber ports on the left and right, all spare optical fiber connection lines occupy a plurality of rows of optical fiber ports, each vertical area of the storage area is used to store optical fiber lines of spare optical fiber connection lines connected to a plurality of consecutive rows of optical fiber ports, the rows of optical fiber ports connected to the spare optical fiber connection lines corresponding to the optical fiber lines stored in the vertical area close to the distribution board are lower than the rows of optical fiber ports connected to the spare optical fiber connection lines corresponding to the optical fiber lines stored in the vertical area far from the distribution board; an upward hook is provided on the upper part of the right partition of each vertical area, and each hook corresponds to a row of optical fiber ports; a notch is provided in the middle of the right partition of each vertical area, and a baffle with the color from the left partition to the right partition is provided at the position corresponding to the notch of the left partition, and a gap is left between the baffle and the notch to allow the optical fiber lines to move out of the storage area.

[0015] It is beneficial to divide the storage area into multiple areas through the vertical areas arranged on the left and right, so that the storage of optical fibers is neater and more efficient; the height of the optical fiber ports allows the robot to move the optical fiber out of the storage area on the left side of the distribution board with a later movement trajectory shorter than the previous movement trajectory; the efficiency of optical fiber organization in the vertical and horizontal directions is enhanced through the corresponding notches and hooks.

[0016] Furthermore, a sorting area is provided between the use area and the distribution board, and a beam splitting area is provided above the use area; the sorting area includes a first substrate and a second substrate distributed vertically in parallel, the first substrate and the second substrate include a plurality of downward hooks, each hook corresponds to a row of optical fiber ports, and an elastic plug is provided between the first substrate and the second substrate, the first substrate and the second substrate are staggered with each other in the vertical direction, so that the elastic plug can completely block the gap between two adjacent hooks of the first substrate and cannot completely block the gap between two adjacent hooks of the second substrate; the beam splitting area includes a plurality of supporting members arranged at different heights in an upper and lower arrangement, each supporting member corresponding to the optical fiber lines of multiple consecutive rows of optical fiber ports; the sorting area includes two front and rear limiting layers, each limiting layer includes a plurality of elastic cantilever rods spaced apart in an upper and lower arrangement.

[0017] It is beneficial to restrict each optical fiber line in the two substrates of the sorting area in turn through the first substrate and the second substrate, so as to prevent multiple optical fiber lines from being entangled with multiple terminals, causing the robot to make mistakes when grabbing the terminals; the resilience of the elastic seal is used to form a gap when it is squeezed by the robot, thereby accommodating the interception of the optical fiber line; each optical fiber line entering the sorting area is horizontally arranged and diverted by two layers of restriction layers and elastic cantilever rods; the longitudinal arrangement and diversion effect of the optical fiber line is achieved by the beam splitting area; the optical fiber line is stored in the through-part, so that the optical fiber lines in the fiber jumper process are sorted sequentially, orderly and repeatably, thereby improving the convenience of remote operation of the fiber jumper action.

[0018] Furthermore, the elastic seal is a serrated sponge distributed between the first substrate and the second substrate, and the thickness of the sponge is equal to the distance between the first substrate and the second substrate; each serration of the sponge is correspondingly arranged between two adjacent hooks, and its shape is a right-angled trapezoid, its hypotenuse is inclined downward, and the length of its short side is greater than the distance between two adjacent hooks on the first substrate.

[0019] It is beneficial to fill the gap between the first substrate and the second substrate with a height difference through the serrated sponge when not squeezed, thereby preventing the optical fiber from accidentally falling, and guiding the optical fiber to slide along the oblique edge to the gap between the hooks of the second substrate when squeezed, thereby achieving the effect that the robot drives the optical fiber to squeeze the serrated sponge, enters between the first substrate and the second substrate, rotates the passing part and releases the optical fiber so that it is blocked by the hook of the second substrate.

[0020] A control method applicable to the system is also provided, wherein the control platform continuously monitors the connection status between communication devices. When a disconnection occurs between two communication devices that have been connected using optical fibers and optical fiber patch cables, the control platform automatically activates a manipulator to restore the connection between the two communication devices using the following method, which specifically includes the following steps:

[0021] S0 removes the fiber optic connection cable connecting the two communication devices, disconnects the two communication devices, selects the fiber optic port connected to the backup fiber of one communication device as the first fiber optic port, and the fiber optic port connected to the backup fiber of the other communication device as the second fiber optic port, where the first fiber optic port has a smaller number than the second fiber optic port;

[0022] S1 selects a spare optical fiber splice cable, moves the manipulator horizontally to the rear of the first terminal, and confines the optical fiber cable in the passage portion from the rear of the first terminal. The manipulator moves horizontally from top to bottom to remove a portion of the optical fiber cable from the storage area, thereby releasing the optical fiber cable.

[0023] S2: The manipulator moves horizontally to the rear of the first terminal, clamps the first terminal and pulls it out of the idle optical fiber port. The manipulator clamps the first terminal and moves horizontally to the first optical fiber port, inserts the first terminal into the first optical fiber port, and releases the first terminal.

[0024] S3 starts from the rear of the first terminal to confine the optical fiber in the passage portion, translates the manipulator from bottom to top to the use area, translates the manipulator from top to bottom in the use area, stores a portion of the optical fiber in the use area, and releases the optical fiber;

[0025] S4: The manipulator moves horizontally to the rear of the second terminal of the spare optical fiber splice cable, and from behind the second terminal, the optical fiber is confined in the passage portion, and the manipulator moves horizontally from top to bottom to remove the remaining portion of the optical fiber from the storage area, thereby releasing the optical fiber;

[0026] S5: The manipulator moves horizontally to the rear of the second terminal, grips the second terminal and pulls it out of the idle optical fiber port. The manipulator grips the second terminal and moves horizontally to the second optical fiber port, inserts the second terminal into the second optical fiber port, and releases the first terminal.

[0027] S6 starts from the rear of the second terminal to confine the optical fiber in the passage portion, moves the manipulator from bottom to top to the use area, and moves the manipulator from top to bottom in the use area to store all the optical fibers in the use area and release the optical fibers. At this point, the selected spare optical fiber is changed to the use optical fiber, and the used spare optical fiber connection line is changed to the use optical fiber connection line;

[0028] S7 tests whether the connection between the two communication devices is restored. If so, the process ends. If not, the above steps are repeated until all spare optical fibers are used up.

[0029] It is beneficial to realize remote monitoring through control methods to detect that when a connection failure occurs in the communication equipment, the optical fiber connection line can be changed to a spare optical fiber connection line by remotely operating the manipulator. According to the design of multiple optical fiber ports on the optical fiber connection terminal, each step of the manipulator on the optical fiber line, including release, grasping, plugging and unplugging, and storage, is more efficient and accurate.

[0030] Furthermore, in step S0, in the process of removing the optical fiber connecting cable connecting the two communication devices, the specific steps are as follows:

[0031] S01: The manipulator is moved horizontally to the rear of the first terminal, and the optical fiber is confined in the passage portion starting from the rear of the first terminal. The manipulator is moved horizontally to move a portion of the optical fiber out of the use area, thereby releasing the optical fiber.

[0032] S02: The manipulator moves horizontally to the rear of the first terminal, grips the first terminal and pulls it out of the first optical fiber port. The manipulator grips the first terminal and moves horizontally to an idle optical fiber port in the recycling area, inserts the first terminal into the optical fiber port, and releases the first terminal.

[0033] S03 starts from the rear of the first terminal to confine the optical fiber in the passage portion, translates the manipulator, stores a portion of the optical fiber in the storage area, and releases the optical fiber;

[0034] S04: The manipulator is moved horizontally to the rear of the second terminal, and the optical fiber is confined in the passage portion starting from the rear of the second terminal. The manipulator is moved horizontally to move the remaining portion of the optical fiber out of the use area, thereby releasing the optical fiber.

[0035] S05: The manipulator moves horizontally to the rear of the second terminal, grips the second terminal and pulls it out of the second optical fiber port. The manipulator grips the second terminal and moves horizontally to another idle optical fiber port in the recycling area, inserts the first terminal into the optical fiber port, and releases the first terminal.

[0036] S06: Starting from the rear of the second terminal, the optical fiber is confined in the passage portion, the manipulator is translated, all the optical fibers are stored in the storage area, and the optical fibers are released.

[0037] The above steps are beneficial to making the contact process between the manipulator and the optical fiber more specific, improving the accuracy of the manipulator's control, and the optical fiber is pulled through and released to a specific position, making the organization and storage of the optical fiber more efficient, which is convenient for the next operation of the manipulator.

[0038] Furthermore, the manipulator also has multiple levels of telescopic freedom to advance and retreat relative to the distribution board, and the multiple levels of telescopic freedom include at least a first position away from the distribution board to ensure that the manipulator and the optical fiber splice cable it clamps do not interfere with other components during translation, a second position close to the rear end of the first terminal or the second terminal inserted in the optical fiber port to enable the optical fiber cable to enter the passing portion, and a third position close to the rear end of the first terminal or the second terminal inserted in the optical fiber port to enable the clamping portion to clamp the first terminal or the second terminal; the first terminal and the second terminal of the spare optical fiber splice cable are respectively inserted into two parallel idle optical fiber ports, and the optical fiber cable starts from the first terminal and enters the storage area from top to bottom, and then winds around in the storage area and exits the storage area from bottom to top to the second terminal;

[0039] The process of storing the optical fiber in the use area in steps S3 and S6 is as follows:

[0040] When the optical fiber is confined in the passage portion, the manipulator is translated to the right to a position between the two base plates of the corresponding hook;

[0041] The manipulator advances to the third position, squeezes the elastic seal to deform it, and translates upward to allow the optical fiber to enter the hook of the first substrate;

[0042] The manipulator retreats to the second position, moves horizontally to the right side of the second substrate, advances to the third position, and moves horizontally upward to allow the optical fiber to enter the hook of the second substrate, and the manipulator retreats to the first position;

[0043] Between the sorting area and the use area, the manipulator moves horizontally from bottom to top, driving the optical fiber line to the beam splitting area. The manipulator moves forward to the second position and crosses the corresponding supporting member from left to right in the beam splitting area.

[0044] The manipulator is translated from top to bottom in the use area, and the manipulator presses the elastic cantilever rod of the rear restriction layer to deform and restore it, so that the optical fiber is stored between the front and rear restriction layers;

[0045] When the optical fiber lines between the front and rear limiting layers affect the robot, all the optical fiber lines between the front and rear limiting layers are moved to the front of the front limiting layer for storage.

[0046] It is beneficial for the manipulator to keep the optical fiber line neat and orderly on the optical connection line terminal when it moves to the storage area after completing the fiber jumper, so as to facilitate the manipulator to repeat the fiber jumper action next time; through the translation and extension of the manipulator in the third position, the optical fiber line is accurately restricted in the hook of the first substrate, through the translation and extension of the manipulator in the second position, the manipulator intercepts the optical fiber line with the second substrate, and through the translation and extension of the manipulator in the first position, the optical fiber line enters the storage area; the stored optical fiber lines are layered and stored through the front and rear restriction layers, so as to improve the storage neatness and efficiency.

[0047] Compared with the existing technology, the beneficial effects of the present invention are: through remote monitoring, the operation and maintenance status of the optical fiber network can be understood and protected in real time; through remote control of the manipulator, the cable jumper tasks in remote or dangerous areas can be replaced by manpower, thereby improving the automation level of cable network operation and maintenance, shortening the time for opening and repairing optical paths, reducing manpower investment, and improving efficiency; through the self-healing collaborative control system, the rapid positioning and self-healing repair effect of unexpected interruptions in the optical fiber network can be achieved, thereby reducing the difficulty of repairing the optical fiber network under the influence of disasters.

[0058] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting the present invention. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0059] Example 1

[0060] like Figure 1-9As shown, this embodiment provides a system for coordinated control of intelligent optical fiber network protection and self-healing, including: a control platform, a plurality of optical fiber connection terminals and a plurality of communication devices connected by optical fibers, wherein the optical fiber connection terminal is used to realize optical fiber connection between communication devices, and the control platform is used to remotely monitor the connection status between communication devices and control the optical fiber connection terminal to restore the connection between communication devices when a disconnection occurs; the optical fiber connection terminal includes: a patch panel, the patch panel is provided with optical fiber ports arranged in a matrix, the optical fiber ports extend from one side of the patch panel to the other side, the communication device includes a working optical fiber and at least one spare optical fiber, the working optical fiber and the spare optical fiber are both connected to the optical fiber port on one side of the patch panel; a plurality of optical fiber connection lines, each optical fiber connection line has a first terminal 110 and a second terminal 120 at both ends, and is connected by an optical fiber line 300 of a certain length, wherein some optical fiber connection lines are working optical fiber connection lines, and their first The terminal 110 and the second terminal 120 are respectively plugged into the optical fiber port on the other side connected to the optical fiber used by different communication devices to realize the connection between the two communication devices. The remaining optical fiber splice is a spare optical fiber splice, and its first terminal 110 and second terminal 120 are respectively plugged into the optical fiber port on the other side that is not in use. The storage area 100 on the left side and the use area 200 on the right side of the wiring board are stored in the storage area 100 for the spare optical fiber splice, and the optical fiber 300 of the use optical fiber splice is stored in the use area 200. The manipulator is remotely controlled by the control platform and has the freedom of translation along the up, down, left and right directions. It includes a clamping portion for clamping the first terminal 110 or the second terminal 120, and a passing portion located behind the clamping portion and capable of accommodating the optical fiber 300 to pass therethrough. The clamping portion can be opened to allow the optical fiber 300 to enter the passing portion, and closed to confine the optical fiber 300 to the passing portion.

[0061] Among them, the optical fiber ports arranged in a matrix on the distribution board have fixed vertical and horizontal coordinates, and each optical fiber port has an independent number, and the numbers gradually increase from top to bottom and from left to right; the manipulator locates the specific position of the optical fiber port according to the vertical and horizontal coordinates, and determines the order of plugging and unplugging the optical fiber connection line and the optical fiber port according to the number.

[0062] In this embodiment, when the first optical fiber port 130 and the second optical fiber port 140 are respectively one up and one down, and the first terminal 110 and the second terminal 120 are respectively one left and one right, the robot will sequentially pull out the first terminal 110, insert it into the first optical fiber port 130, pull out the second terminal 120, and insert it into the second optical fiber port 140.

[0063] In this embodiment, the control platform is the master station system, and the optical fiber line 300 connection terminal is a station-end device. The master station system is installed in the communication room of the ground control center and includes servers, workstations, switches, firewalls, encryption gateways, and other equipment. The management platform software implements data management such as station-end optical cable routing, fiber core resources, and business information. It can also transmit instructions to the station-end device through the power communication dedicated network to control the functions of manipulator plugging and unplugging, inspection testing, and video monitoring of the entire operation process. The station-end device is installed in each substation and is connected to the optical equipment and existing optical fiber distribution equipment respectively. It can receive master station instructions to realize automatic switching between optical paths. Specific functions include executing master station instructions to complete fiber patching between different ports and realizing designated port optical path testing through embedded OTDR, light source, and optical power meter. Optical equipment includes SDH equipment, ASON equipment, OTN equipment, data network equipment, and protection equipment.

[0064] In this embodiment, through the above-mentioned optical fiber distribution control method, first, an optical path remote intelligent switching device is developed that can support remote access to the station-end optical fiber distribution port and perform fiber jumper operations. The device should meet the following basic functions: it has the function of remote control to quickly and accurately switch the optical fiber core switching; second, a single device can meet the total number of communication optical cable cores in the existing substation, and has the function of solving the fiber jumper requirements between any two cores of the redundant optical cores of the substation; third, the fiber jumper process has real-time monitoring function, video monitoring and uploading function, high-definition video pixels ≥3MP, and can trace back actions; fourth, it has fiber jumper anti-entanglement and physical dustproof functions, and the optical fiber interface is compatible with dust cap coverage.

[0065] In this embodiment, a combination of software and hardware is used to prevent remote misoperation of optical fiber wiring, or to provide a timely error correction mechanism after an error occurs. In terms of software design, the system automatically locks the optical fiber port and the corresponding optical fiber core during fiber patching operations, and automatically determines the receiving and receiving optical ports (TX to RX) when patching with optical modules. If an optical module TX to TX is manually connected, the software has an automatic error correction reminder function, preventing the "optical path adjustment" command from being issued. When performing automatic light source or OTDR testing, the software first verifies whether the opposite optical device is disconnected to prevent the test light source from damaging the opposite optical device. For other human-induced fiber patching errors and when an instruction has just been issued and error correction is found, a "pause" or "stop" function is added to the main station platform management software to prevent the next erroneous instruction from being issued.

[0066] The manipulator also has multiple levels of telescopic freedom of moving forward and backward relative to the distribution board, and the multiple levels of telescopic freedom include at least a first position away from the distribution board to ensure that the manipulator and the optical fiber connection cable it clamps do not interfere with other components during translation, a second position close to the rear end of the first terminal 110 or the second terminal 120 inserted in the optical fiber port, so that the optical fiber line 300 can enter the pass-through part, and a third position close to the rear end of the first terminal 110 or the second terminal 120 inserted in the optical fiber port, so that the clamping part can clamp the first terminal 110 or the second terminal 120.

[0067] In this embodiment, the hardware structure design implements the following measures to prevent incorrect robot movement. First, a gantry with a combination of precision guide rails is used to achieve precise positioning of the X and Y axes, and then the Z axis with a high-precision stepper motor is used to precisely position the robot, thereby achieving high-precision positioning of three-dimensional coordinates. Second, a high-precision encoder feedback circuit is used to ensure stable and secure gripping of the robot, preventing the robot from loosening its grip on the fiber optic plug. Third, a high-precision MU socket with a 0.1mm pitch is used to prevent mis-insertion and reduce insertion loss. Fourth, a 5MP high-definition camera is installed on the robot arm to remotely monitor the device's movement in real time, providing video playback and tracing historical operation processes.

[0068] The manipulator also has a rotational freedom of rotation about a certain axis of its own. A V-shaped elastic mechanism is provided in the passage portion for supporting the optical fiber 300. The storage area 100 and the use area 200 are provided with a release assistance mechanism. When the manipulator drives the optical fiber 300 to translate, the passage portion is maintained as a through hole that passes through the left and right sides. In the process of releasing the optical fiber 300, the manipulator rotates until the passage portion becomes a through hole that passes through the top and bottom.

[0069] In this embodiment, when the V-shaped elastic mechanism is opened, the manipulator moves forward to allow the optical fiber 300 to enter the passage portion. When the V-shaped elastic mechanism is closed, the manipulator grasps the optical fiber 300 in the through-hole formed in the passage portion. The manipulator can control the release direction of the optical fiber 300 by rotating. The release assist mechanism is used to intercept the optical fiber 300 that is individually removed from the bundle in the storage area 100.

[0070] The fiber optic ports arranged in a matrix on the distribution board are divided into an occupied area and a recovery area. The number of fiber optic ports in the occupied area is greater than that in the recovery area. The recovery area and the occupied area are distributed on the left and right. The working optical fibers and spare optical fibers of the communication equipment are connected to the fiber optic ports in the occupied area. The spare optical fiber connection lines are connected to the optical fiber ports on the upper layer of the working optical fiber connection lines. The first terminal 110 and the second terminal 120 of the spare optical fiber connection line are connected to two adjacent optical fiber ports.

[0071] In this embodiment, the occupied area is green, the recycling area is gray, the leftmost blue fiber optic port on the distribution panel is pending review - the internal port is not linked, the 8 columns of gray fiber optic ports near the left are faulty / C-zone ports, and the 12 columns of green fiber optic ports near the right are unlinked - the internal port is not linked. When the 12 columns of green fiber optic ports are linked - the internal port is linked, it changes from green to orange.

[0072] In this embodiment, the optical fiber distribution intelligent operation and maintenance robot has a built-in light source, optical power meter and OTDR module, supports remote automatic testing of the spare fiber cores of the station-end optical cable, can automatically upload test data and documents to the management platform, and will prompt the operator for defect data that exceeds the set value.

[0073] One of these features is the automatic testing of fiber core attenuation. During pre-set idle periods (except when the equipment is adjusting the optical path), the system automatically sends the available fiber cores connected between the two stations. The manipulators at both ends align the ends of the fiber core to be tested, activate the built-in light source power, and automatically read the overall attenuation data of the fiber core. After each fiber core is tested, the device automatically uploads the attenuation value of the core and automatically calculates the average attenuation per kilometer. The test and calculation results are automatically sent to the main station management platform server for storage.

[0074] The second is automatic detection of fiber breakpoints. The master station management platform sends an OTDR command, and the station-side manipulator docks one end of the fiber core being tested and activates the OTDR instrument. After automatic testing, images and event documentation of the fiber core test event are generated, and the data of the fiber core is automatically reported to the master station management platform server.

[0075] Third, it supports the automatic generation of optical fiber inspection reports and centralized storage and export management of test files. It can export spare fiber core test files with one click according to the file format required by the Southern Power Grid OMS, reducing the traditional OTDR test curve export, naming and compression steps, and improving work efficiency. At the same time, by establishing a spare fiber core health file, it can grasp the trend of fiber core attenuation data changes and promptly discover hidden dangers and defects.

[0076] The storage area 100 includes a plurality of vertical areas arranged left and right, separated by a plurality of vertical partitions. The first terminal 110 and the second terminal 120 of each spare optical fiber patch cord are connected to two adjacent optical fiber ports on the left and right. All spare optical fiber patch cords occupy a plurality of rows of optical fiber ports. Each vertical area of the storage area 100 is used to store optical fiber lines 300 of spare optical fiber patch cords connected to a plurality of consecutive rows of optical fiber ports. The rows of optical fiber ports connected to the spare optical fiber patch cords corresponding to the optical fiber lines 300 stored in the vertical area close to the wiring board are lower than the rows of optical fiber ports connected to the spare optical fiber patch cords corresponding to the optical fiber lines 300 stored in the vertical area far from the wiring board. An upward hook is provided on the upper portion of the right partition of each vertical area, and each hook corresponds to a row of optical fiber ports. A notch is provided in the middle portion of the right partition of each vertical area. A baffle with the color from the left partition to the right partition is provided at the position corresponding to the notch on the left partition. A gap is left between the baffle and the notch to allow the optical fiber lines 300 to move out of the storage area 100.

[0077] In this embodiment, the vertical area arranges and places multiple bundles of optical fiber lines 300 in sequence, and the optical fiber port row corresponding to each hook allows the optical fiber line 300 to be separated nearby when it is separated from the bundle. The recess in each vertical area allows the optical fiber line 300 to be temporarily separated between the two baffles to avoid entanglement of the optical fiber line 300 when the optical fiber port is inserted after the terminal is pulled out in the subsequent steps.

[0078] A sorting area is also provided between the use area 200 and the distribution board, and a beam splitting area is also provided above the use area 200; the sorting area includes a first substrate 410 and a second substrate 420 distributed vertically and parallel, the first substrate 410 and the second substrate 420 include a plurality of downward hooks, each hook corresponding to a row of optical fiber ports, and an elastic plug 430 is provided between the first substrate 410 and the second substrate 420, the first substrate 410 and the second substrate 420 are staggered with each other in the vertical direction, so that the elastic plug 430 can completely block the gap between two adjacent hooks of the first substrate 410 and cannot completely block the gap between two adjacent hooks of the second substrate 420; the beam splitting area includes a plurality of supporting members arranged at different heights in an upper and lower arrangement, each supporting member corresponding to the optical fiber lines 300 of multiple consecutive rows of optical fiber ports; the sorting area includes two front and rear limiting layers, each limiting layer includes a plurality of elastic cantilever rods spaced apart in an upper and lower arrangement.

[0079] In this embodiment, the finishing area is used to store and organize the optical fiber line 300 after the fiber jumper is completed, and the beam splitting area is used for the initial storage state of the optical fiber line 300 bundle. The first substrate 410 can prevent the optical fiber line 300 from accidentally entering

[0080] The elastic seal 430 is a serrated sponge distributed between the first substrate 410 and the second substrate 420, and the thickness of the sponge is equal to the distance between the first substrate 410 and the second substrate 420; each serration of the sponge is correspondingly arranged between two adjacent hooks, and its shape is a right-angled trapezoid, its hypotenuse is inclined downward, and the length of its short side is greater than the distance between two adjacent hooks on the first substrate 410.

[0081] In this embodiment, the serrated sponge is placed between the first substrate 410 and the second substrate 420, with the side surfaces being in contact with the inner wall of the first substrate 410 and the inner wall of the second substrate 420. The hook gap on the first substrate 410 is blocked by the side surfaces of the serrated sponge, preventing optical fiber lines 300 other than the optical fiber lines 300 grasped by the robot from accidentally entering between the two substrates; there is a gap between the hook gap on the second substrate 420 and the side surfaces of the serrated sponge, so that after the robot squeezes the sponge, the optical fiber line 300 in the passing part automatically slides along the oblique edge into the gap, and when the robot detaches from the sponge and rotates upward, the optical fiber line 300 in the passing part is intercepted in the hook gap of the second substrate 420.

[0089] S5: The manipulator moves horizontally to the rear of the second terminal, grips the second terminal and pulls it out of the idle optical fiber port. The manipulator grips the second terminal and moves horizontally to the second optical fiber port, inserts the second terminal into the second optical fiber port, and releases the first terminal.

[0090] S6 starts from the rear of the second terminal to confine the optical fiber in the passage portion, moves the manipulator from bottom to top to the use area, and moves the manipulator from top to bottom in the use area to store all the optical fibers in the use area and release the optical fibers. At this point, the selected spare optical fiber is changed to the use optical fiber, and the used spare optical fiber connection line is changed to the use optical fiber connection line;

[0091] S7 tests whether the connection between the two communication devices is restored. If so, the process ends. If not, the above steps are repeated until all spare optical fibers are used up.

[0098] S06: Starting from the rear of the second terminal, the optical fiber is confined in the passage portion, the manipulator is translated, all the optical fibers are stored in the storage area, and the optical fibers are released.

[0099] The manipulator also has multiple levels of telescopic freedom for moving forward and backward relative to the wiring board, and the multiple levels of telescopic freedom include at least a first position away from the wiring board to ensure that the manipulator and the optical fiber splice cable it clamps do not interfere with other components during translation, a second position close to the rear end of the first terminal or the second terminal inserted in the optical fiber port to enable the optical fiber cable to enter the passage portion, and a third position close to the rear end of the first terminal or the second terminal inserted in the optical fiber port to enable the clamping portion to clamp the first terminal or the second terminal; the first terminal and the second terminal of the spare optical fiber splice cable are respectively inserted into two parallel idle optical fiber ports, and the optical fiber cable starts from the first terminal and enters the storage area from top to bottom, and then winds around in the storage area and exits the storage area from bottom to top to the second terminal;
