Description

Technical Field

[0001] The present invention relates to the field of optical fibers, and more particularly to a device and method for analyzing and judging comprehensive optical cable faults based on an optical fiber distribution robot. Background Art

[0002] The electric power communication network is primarily based on fiber-optic communications, which is crucial for power dispatching, automation, and relay protection. Currently, the power communication optical cable network is large and complex, susceptible to both natural and human factors. Optical cable failures are one of the main reasons for disrupting power communication services. Therefore, strengthening the monitoring and maintenance of optical cables is crucial to ensuring the operation of 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, and key communication equipment now supports remote alarm monitoring and network management operations. However, the operation and maintenance of the power cable network still relies on manual maintenance and lacks automated operation and maintenance technology support, which is a key limitation in operational efficiency. For example, optical line opening and emergency repairs are time-consuming, labor-intensive, and inefficient; optical cable outages are slow to locate, impacting repair efficiency; and 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. Summary of the Invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a device and method for comprehensive optical cable fault analysis based on an optical fiber distribution robot, which is used to solve the technical problems of lack of automation technology in the operation and maintenance of optical cable networks, resulting in a long time, high manpower and low efficiency in opening and repairing optical paths; slow positioning of optical cable breaks and disasters affecting repair efficiency; long fiber core detection and inconvenient data analysis.

[0005] The technical solution adopted by the present invention is to provide a device for comprehensive optical cable fault analysis based on an optical fiber wiring robot, comprising:

[0006] Cabinet, including the incoming and outgoing lines and maintenance side;

[0007] The distribution board is installed in the cabinet to separate the space inside the cabinet into the incoming and outgoing line side and the maintenance side;

[0008] The wiring robot is installed in the maintenance side and includes a support frame, a manipulator and a motion device. The motion device is used to control the translation and grasping of the manipulator, and the support frame is used to support the movement of the manipulator and the motion device.

[0009] A winding device is installed inside the incoming and outgoing line side and winds multiple connecting optical fibers. One end of each connecting optical fiber is a connecting terminal, and the other end is a connection end;

[0010] Multiple optical fiber connecting lines are arranged inside the maintenance side. Both ends of each optical fiber connecting line are a first terminal and a second terminal respectively, and are connected by an optical fiber line with a certain length in between;

[0011] The wiring board is provided with optical fiber ports arranged in a matrix. The optical fiber ports extend from the incoming and outgoing line side of the wiring board to the maintenance side. The optical fiber lines of other devices enter the cabinet from the incoming and outgoing line side, are welded to the connecting optical fibers and then connected to the optical fiber ports on the incoming and outgoing line side of the wiring board through the connecting terminals. The maintenance side of the optical fiber ports connected to the connecting terminals is connected to the optical fiber connecting lines to achieve the connection between two other devices. This part of the optical fiber connecting lines is the used optical fiber connecting lines. The first terminals and second terminals of other optical fiber connecting lines are respectively plugged into the optical fiber ports on the incoming and outgoing line side that are not connected to the connecting terminals. This part of the optical fiber connecting lines is the spare optical fiber connecting lines. The robot realizes the judgment and recovery of connection faults between other devices by switching different used optical fiber connecting lines and spare optical fiber connecting lines;

[0012] Among them, the wiring board is the first coordinate system, each optical fiber port has an independent coordinate, the support frame is the second coordinate system, and the manipulator identifies the coordinates of each optical fiber port according to its position in the second coordinate system and the relative position of the second coordinate system relative to the first coordinate system to achieve the positioning of the optical fiber ports;

[0013] The manipulator realizes the switching between the used optical fiber connecting lines and the spare optical fiber connecting lines by plugging and unplugging the first terminals or second terminals of the used optical fiber connecting lines and the spare optical fiber connecting lines;

[0014] The optical fiber ports have fixed numbers, and the numbers increase gradually from top to bottom and from left to right. The manipulator judges the sequence of plugging and unplugging the first terminals or second terminals of the optical fiber connecting lines according to the numbers of the optical fiber ports;

[0015] The wiring robot further includes a testing device. The testing device is used to test whether there are faults in the optical paths of other devices connected to the incoming and outgoing line side from the maintenance side, and includes a tester and a first testing terminal connected to the tester. The first testing terminal is arranged on the manipulator.

[0016] It is beneficial to use the wiring board as the first coordinate system and the support frame as the second coordinate system, so that when the manipulator inserts and removes the optical fiber connection line, it can accurately adjust the position according to the coordinate system to improve the operation stability of the manipulator; use the testing device to assist in judging the position of the optical fiber wiring fault and reduce the impact of fault detection on the optical fiber during use; set the first test terminal on the manipulator so that the optical fiber connection line during the test is disconnected from the cabinet, thereby ensuring the accuracy of the test.

[0017] Furthermore, it also includes a second test terminal connected to the tester. The second test terminal extends from the maintenance side to the incoming and outgoing line side and is connected to an optical fiber port on the incoming and outgoing line side. The optical fiber port on the maintenance side corresponding to this optical fiber port is the test port.

[0018] It is beneficial to form an intermediate point between the connected devices through the connection between the second test terminal and the optical fiber port, which is convenient for judging whether the two connected devices are faulty according to the states of the first test terminal and the second test terminal respectively.

[0019] Furthermore, the optical fiber ports on the wiring board are divided into an upper layer area and a lower layer area. The spare optical fiber connection line is inserted on the maintenance side of the upper layer area, and the connection terminal and the used optical fiber connection line are respectively inserted on the incoming and outgoing line side and the maintenance side of the lower layer area;

[0020] The lower layer area is divided into an occupied area and a recycling area. The number of optical fiber ports in the occupied area is more than that in the recycling area. The recycling area and the occupied area are distributed left and right. The connection terminal and the used optical fiber connection line are respectively inserted on the incoming and outgoing line side and the maintenance side of the used area;

[0021] The array - arranged optical fiber ports are adjacently set in rows in the left - right direction and are separated in the up - down direction, forming a walking space for the manipulator to pass through between the rows;

[0022] On the maintenance side, a storage area is arranged on the left side of the wiring board, and a use area is arranged on the right side. The optical fiber line of the spare optical fiber connection line extends leftward and is stored in the storage area, and the optical fiber line of the used optical fiber connection line extends rightward and is stored in the use area.

[0023] It is beneficial to effectively separate the optical fiber bundles through the upper layer area and the lower layer area, prevent the wire bundles from being entangled and causing the manipulator to grasp incorrectly, which affects the accuracy of automatic optical fiber line insertion and removal.

[0024] Further, the manipulator includes a clamping portion for clamping the first terminal or the second terminal, and a through portion located behind the clamping portion and capable of accommodating the optical fiber line to pass through therein. The clamping portion can be opened to allow the optical fiber line to enter the through portion and closed to restrict the optical fiber line within the through portion; the actuating device further includes a telescopic mechanism for controlling the forward and backward movement of the manipulator. The telescopic mechanism controls the manipulator to have multiple telescopic degrees of freedom in moving forward and backward relative to the wiring board. The multiple telescopic degrees of freedom at least include a first position away from the wiring board to ensure that the manipulator and the optical fiber connection line it holds 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 into the optical fiber port to allow the optical fiber line to enter the through portion, and a third position close to the rear end of the first terminal or the second terminal inserted into the optical fiber port to allow the clamping portion to clamp the first terminal or the second terminal;

[0025] The actuating device further includes a rotating mechanism for controlling the rotation of the manipulator. When the manipulator moves the optical fiber line in translation, the through portion is maintained as a through hole penetrating left and right; during the process of releasing the optical fiber line, the rotating mechanism drives the manipulator to rotate until the through portion becomes a through hole penetrating up and down.

[0026] It is beneficial to achieve high-precision and flexible positioning of the manipulator in the X-axis, Y-axis, and Z-axis through multiple telescopic degrees of freedom, and avoid colliding with the wiring board during movement; the first position restricts the freedom degree of the manipulator in the plane parallel to the wiring board, the second position restricts the freedom degree when the manipulator holds the optical fiber line and moves it together, and the third position restricts the freedom degree of the manipulator to clamp the first terminal or the second terminal, so that the manipulator can fully contact the optical fiber line, the first terminal, and the second terminal without colliding with other components on the wiring board; it is beneficial to complete the grasping action of the optical fiber line through the clamping portion, complete the movement action of driving the optical fiber line through the through portion, and complete the release and storage actions of the optical fiber line through the rotating mechanism.

[0027] Further, the storage area includes a plurality of vertically arranged vertical areas separated by a number of vertical partitions. The first terminals and second terminals 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 number of rows of optical fiber ports. Each vertical area in the storage area is used to store the optical fiber lines of the spare optical fiber connection lines connected to consecutive rows of optical fiber ports. The row of optical fiber ports to which the spare optical fiber connection line corresponding to the optical fiber line stored in the vertical area closer to the wiring board is connected is lower than the row of optical fiber ports to which the spare optical fiber connection line corresponding to the optical fiber line stored in the vertical area farther from the wiring board is connected;

[0028] An upward hook is provided at the upper part of the right partition of each vertical area, and each hook corresponds to a row of optical fiber ports;

[0029] In the middle of the right partition of each vertical area, there is a notch, and at the position corresponding to the notch on the left partition, there is a baffle extending from the left partition to the right partition in terms of color. There is a gap between the baffle and the notch, which is used to allow the optical fiber cable to move out of the storage area;

[0030] There is also an arrangement area between the use area and the wiring board, and there is a beam splitting area above the use area;

[0031] The arrangement area includes a first substrate and a second substrate arranged vertically and parallel to each other. The first substrate and the second substrate include a plurality of downward hook buckles, and each hook buckle corresponds to a row of optical fiber ports. There is an elastic seal 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 seal can completely seal the gap between two adjacent hook buckles of the first substrate and cannot completely seal the gap between two adjacent hook buckles of the second substrate;

[0032] The beam splitting area includes a plurality of supporting members arranged vertically at different heights. Each supporting member corresponds to the optical fiber cables of a continuous multiple rows of optical fiber ports;

[0033] The arrangement area includes two layers of limiting layers in the front and back. Each layer of limiting layer includes a plurality of elastic cantilever rods distributed at intervals in the vertical direction.

[0034] It is beneficial to divide the storage area into multiple parts through the vertical areas arranged left and right, making the storage of optical fiber cables more tidy and efficient; due to the height of the rows of optical fiber ports, when the manipulator moves the optical fiber cable out of the storage area on the left side of the wiring board, the movement track of the latter time can be less than that of the previous time; through the correspondence between the notch and the hook buckle, the arrangement efficiency of the optical fiber cable in the vertical and horizontal directions is enhanced; each optical fiber cable is successively restricted in the two substrates of the arrangement area by the first substrate and the second substrate to prevent entanglement between multiple optical fiber cables and multiple terminals, so that the manipulator makes mistakes when grasping the terminals; due to the resilience of the elastic seal, a gap is formed when it is squeezed by the manipulator, so as to accommodate the interception of the optical fiber cable; through the two layers of limiting layers and the elastic cantilever rods, a lateral arrangement diversion effect is achieved for each optical fiber cable entering the arrangement area; through the beam splitting area, a longitudinal arrangement diversion effect of the optical fiber cable is achieved; through the storage steps of the optical fiber cable in the penetration part, the optical fiber cable in the fiber optic jumper process is sorted successively, orderly and repeatedly, improving the convenience of the remote operation of the fiber optic jumper action.

[0035] There is also provided a method for comprehensively judging optical cable faults applicable to the described device. Among them, the other devices include multiple groups of a first device and a second device connected through a distribution board and using optical fiber connecting wires. The first device and the second device include an optical fiber for use and at least one spare optical fiber. Both the optical fiber for use and the spare optical fiber are connected to the optical fiber ports on the incoming and outgoing line sides. The maintenance side of the optical fiber port corresponding to the optical fiber for use is connected through an optical fiber connecting wire, and the maintenance side of the optical fiber port corresponding to the spare optical fiber is not connected. When the connection between the first device and the second device is interrupted, the robot judges the fault through the following method:

[0036] T1 controls the manipulator to unplug the first terminal of the optical fiber connecting wire connected to the first device and insert it into the first test terminal, starts the tester for testing, and controls the manipulator to restore the connection;

[0037] T2 controls the manipulator to unplug the second terminal of the optical fiber connecting wire connected to the second device and insert it into the first test terminal, starts the tester for testing, and controls the manipulator to restore the connection;

[0038] Judge the fault through the following combination of test results:

[0039] When T1 is connected and T2 is connected, the optical fiber connecting wire is open;

[0040] When T1 is not connected and T2 is connected, the optical fiber for use of the first device is open;

[0041] When T1 is connected and T2 is not connected, the optical fiber for use of the second device is open;

[0042] When T1 is not connected and T2 is not connected, the optical fibers for use of the first and second devices are open;

[0043] Corresponding to the above judgment results, the robot restores the connection between the first device and the second device through the following method:

[0044] R1 When the optical fiber connecting wire is open, replace the optical fiber connecting wire with a spare optical fiber connecting wire;

[0045] R2 When the optical fiber for use of the first device is open, connect the first terminal of the optical fiber connecting wire to the spare optical fiber of the first device;

[0046] R3 When the optical fiber for use of the second device is open, connect the second terminal of the optical fiber connecting wire to the spare optical fiber of the second device;

[0047] R4 When the optical fibers for use of the first and second devices are open, replace the optical fiber connecting wire with a spare optical fiber connecting wire, connect the first terminal of the spare optical fiber connecting wire to the spare optical fiber of the first device, and connect the second terminal of the spare optical fiber connecting wire to the spare optical fiber of the second device.

[0048] It is beneficial to disconnect the optical fiber connecting wire from the first device and the second device respectively in T1 and T2, and determine whether there is a connectivity failure in the used optical fiber and the used optical fiber connecting wire on the first device and the second device. Then, the robot implements corresponding recovery methods according to different faults, so as to achieve the previous step of automatically judging faults and automatically recovering in the remote control optical fiber distribution network.

[0049] Further, when the T1 test shows non-connection, the following steps are also included before controlling the manipulator to restore the connection:

[0050] T3 controls the manipulator to insert the first terminal into the test port, starts the tester for testing, and then controls the manipulator to restore the connection;

[0051] [[ID=X]]When the T2 test shows non-connection, the following steps are also included before controlling the manipulator to restore the connection:

[0052] T4 controls the manipulator to insert the second terminal into the test port, starts the tester for testing, and then controls the manipulator to restore the connection;

[0053] The faults are judged through the following combinations of test results:

[0054] When T3 is connected, the used optical fiber of the first device is broken;

[0055] When T3 is not connected, the used optical fiber connecting wire or the used optical fiber of the second device is broken;

[0056] When T4 is connected, the used optical fiber of the second device is broken;

[0057] When T4 is not connected, the used optical fiber connecting wire or the used optical fiber of the first device is broken;

[0058] Corresponding to the above judgment results, the robot restores the connection between the first device and the second device through the following methods:

[0059] R5 When the used optical fiber of the first device is broken, connect the first terminal of the used optical fiber connecting wire to the spare optical fiber of the first device;

[0060] R6 When the used optical fiber connecting wire or the used optical fiber of the second device is broken, replace the used optical fiber connecting wire with a spare optical fiber connecting wire, connect the first terminal of the spare optical fiber connecting wire to the spare optical fiber of the first device, and connect the second terminal of the spare optical fiber connecting wire to the spare optical fiber of the second device;

[0061] R7 When the used optical fiber of the second device is broken, connect the second terminal of the used optical fiber connecting wire to the spare optical fiber of the second device;

[0062] When using an optical fiber connection cable or when the first device has an optical fiber break, replace the used optical fiber connection cable with a spare optical fiber connection cable. Connect the first terminal of the spare optical fiber connection cable to the spare optical fiber of the first device, and connect the second terminal of the spare optical fiber connection cable to the spare optical fiber of the second device.

[0063] It is beneficial to connect the test terminals to the first device and the second device respectively in T3 and T4, and determine whether there is a connectivity failure in the used optical fiber and the used optical fiber connection cable on the first device and the second device. Then, according to different faults, the robot implements corresponding recovery methods, thus realizing the next step of automatically judging and automatically recovering faults in the remote-controlled optical fiber distribution network.

[0064] Further, the specific processes of the methods R4, R6 or R8 are as follows:

[0065] S0 Remove the used optical fiber connection cable connecting the first device and the second device, disconnect the first device and the second device. Select the optical fiber port connected to a spare optical fiber of the first device as the first optical fiber port, and the optical fiber port connected to a spare optical fiber of the second device as the second optical fiber port. The number of the first optical fiber port is less than that of the second optical fiber port.

[0066] S1 Select a spare optical fiber connection cable. Translate the manipulator to the rear of the first terminal. Starting from the rear of the first terminal, confine the optical fiber line within the through portion, translate the manipulator downward, move a part of the optical fiber line out of the storage area, and release the optical fiber line.

[0067] S2 Translate the manipulator to the rear of the first terminal, clamp the first terminal and pull it out of the idle optical fiber port. The manipulator clamps the first terminal and translates it to the first optical fiber port, inserts the first terminal into the first optical fiber port, and releases the first terminal.

[0068] S3 Starting from the rear of the first terminal, confine the optical fiber line within the through portion, translate the manipulator upward to the use area, and then translate the manipulator downward within the use area to store a part of the optical fiber line in the use area, and release the optical fiber line.

[0069] S4 Translate the manipulator to the rear of the second terminal of the spare optical fiber connection cable. Starting from the rear of the second terminal, confine the optical fiber line within the through portion, translate the manipulator downward, move the remaining part of the optical fiber line out of the storage area, and release the optical fiber line.

[0070] S5 Translate the manipulator to the rear of the second terminal, clamp the second terminal and pull it out of the idle optical fiber port. The manipulator clamps the second terminal and translates it to the second optical fiber port, inserts the second terminal into the second optical fiber port, and releases the first terminal.

[0071] 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;

[0072] S7 tests whether the connection between the first device and the second device is restored. If so, the process ends. If not, the above steps are repeated until all spare optical fibers are used up.

[0073] The above steps are helpful in replacing the used optical fiber patch cord with a spare optical fiber patch cord.

[0074] Furthermore, in step S0, in the process of removing the optical fiber connection cable connecting the first device and the second device, the specific steps are as follows:

[0075] 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.

[0076] 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.

[0077] 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;

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The above steps are beneficial for separating the plugging and unplugging of the optical fiber connection cables of the first device and the second device, so as to achieve the automatic plugging and unplugging effect of the optical fiber distribution robot.

[0082] Further, when the first device or the second device includes multiple spare optical fibers, the specific processes of methods R2, R3, R5, and R7 are to select the spare optical fiber whose connected optical fiber port is closest to the optical fiber port connected by the used optical fiber, connect the used optical fiber patch cord to this spare optical fiber, and test whether the first device and the second device are restored to connection. If the connection is restored, the process ends; if not, repeat the above steps one by one in the order from the closest to the farthest distance from the optical fiber port connected by the used optical fiber until all spare optical fibers are used up.

[0083] It is beneficial to avoid the failure of the spare optical fibers and prevent the optical fiber distribution network from being unable to resume normal connection through the setting of multiple spare optical fibers.

[0084] Compared with the prior art, the beneficial effects of the present invention are as follows: replacing manual labor with an optical fiber distribution robot to remotely operate the restoration of an optical cable interruption, quickly and efficiently completing the optical path emergency repair; achieving the technical effect of accurately positioning the fault location while avoiding manual labor going to dangerous, remote disaster sites.

Detailed implementation manners

[0098] The attached drawings of the present invention are only for illustrative purposes and should not be construed as a limitation to the present invention. For better illustration of the following embodiments, some components in the attached drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted.

[0099] Embodiment 1

[0100] As Figures 1-12 shown, the technical solution adopted in this embodiment is to provide a device for comprehensive fault judgment of optical cable based on an optical fiber wiring robot, including:

[0101] A cabinet, including an incoming and outgoing line side and a maintenance side;

[0102] A wiring board, arranged in the cabinet, separating the space inside the cabinet into an incoming and outgoing line side and a maintenance side;

[0103] A wiring robot, installed inside the maintenance side, including a support frame, a manipulator and an action device, the action device is used to control the translation and grasping of the manipulator, and the support frame is used to support the movement of the manipulator and the action device;

[0104] A winding device, installed inside the incoming and outgoing line side, winding multiple connecting optical fibers, one end of the connecting optical fiber is a connecting terminal, and the other end is a connection end;

[0105] Multiple optical fiber connection cables, arranged inside the maintenance side, both ends of each optical fiber connection cable are respectively the first terminal 110 and the second terminal 120, and are connected by an optical fiber cable 300 with a certain length in between;

[0106] The wiring board is provided with fiber optic ports arranged in a matrix. The fiber optic ports extend from the incoming / outgoing line side of the wiring board to the maintenance side. The fiber optic cables 300 of other devices enter the cabinet from the incoming / outgoing line side, are welded to the connecting fiber optic cables, and then connected to the fiber optic ports on the incoming / outgoing line side of the wiring board through connecting terminals. The maintenance side of the fiber optic ports connected to the connecting terminals is connected to the fiber optic connecting cables, realizing the connection between two other devices. This part of the fiber optic connecting cables is the used fiber optic connecting cable 313. The first terminals 110 and the second terminals 120 of other fiber optic connecting cables are respectively inserted into the fiber optic ports on the incoming / outgoing line side that are not connected to the connecting terminals. This part of the fiber optic connecting cables is the spare fiber optic connecting cables. The robot realizes the judgment and recovery of connection failures between other devices by switching different used fiber optic connecting cables 313 and spare fiber optic connecting cables;

[0107] Among them, the wiring board is the first coordinate system, each fiber optic port has an independent coordinate, the support frame is the second coordinate system, and the manipulator identifies the coordinates of each fiber optic port according to its position in the second coordinate system and the relative position of the second coordinate system relative to the first coordinate system, realizing the positioning of the fiber optic ports;

[0108] The manipulator realizes the switching between the used fiber optic connecting cable 313 and the spare fiber optic connecting cable by plugging and unplugging the first terminal 110 or the second terminal 120 of the used fiber optic connecting cable 313 and the spare fiber optic connecting cable;

[0109] The fiber optic ports have fixed numbers, and the numbers increase gradually from top to bottom and from left to right. The manipulator judges the sequence of plugging and unplugging the first terminal 110 or the second terminal 120 of the fiber optic connecting cable according to the numbers of the fiber optic ports;

[0110] The wiring robot further includes a testing device. The testing device is used to test whether there is a fault in the optical path of other devices connected to the incoming / outgoing line side from the maintenance side, including a tester 600 and a first test terminal connected to the tester 600. The first test terminal is arranged on the manipulator.

[0111] In this embodiment, the fiber optic distribution robot is embedded with a light source, an optical power meter, and an OTDR module, which supports automatic testing of the spare fiber cores at the station end remotely. It can automatically upload the test data and documents to the management platform, and prompt the operator for defect data exceeding the set value. First, it is the automatic testing of the fiber core attenuation value. During the pre-set idle business time period (except when the device is adjusting the optical path), the system automatically issues the connected spare fiber cores between two stations. After the two manipulators dock at both ends of the fiber core to be tested, the embedded light source optical power is enabled, and the overall attenuation data of the fiber core is automatically tested. After each fiber core is detected, the device automatically uploads the attenuation value of the fiber core, and automatically calculates the average attenuation value per kilometer. The test and calculation results are automatically sent to the main station management platform server for storage. Second, it is the automatic detection of the fiber break point position. The main station management platform sends an OTDR instruction. After the station end manipulator docks at one end of the fiber core to be detected, the OTDR instrument is enabled. After automatic testing, the image and event document of the fiber core test event are obtained, and the data of the fiber core is automatically reported to the main station management platform server. Third, it supports the automatic generation of fiber regular inspection reports and centralized storage and export management of test files. It can export the spare fiber core test files in one key in the file format required by the South China Grid OMS, reducing the traditional links such as exporting, naming, and compressing the OTDR test curves, and improving work efficiency. At the same time, by establishing a health record for the spare fiber cores, the changing trend of the fiber core attenuation data can be mastered, and potential hazards and defects can be discovered in time.

[0112] It further includes a second test terminal connected to the tester 600. The second test terminal extends from the maintenance side to the incoming and outgoing line side and is connected to a fiber optic port on the incoming and outgoing line side. The fiber optic port on the maintenance side corresponding to this fiber optic port is the test port.

[0113] In this embodiment, the first test terminal and the second test terminal divide the path connected to the fiber optic distribution robot into two segments. When the tester 600 is connected to different terminals, the first device 510 and the second device 520 are respectively disconnected from the cabinet. Based on the detection results of the tester 600, it is judged whether there are faults in the fiber 311 used by the first device 510 on the incoming and outgoing line side, the fiber 312 used by the second device 520, and the fiber optic connection cable 313 used on the maintenance side.

[0114] The fiber optic ports on the distribution board are divided into an upper layer area and a lower layer area. The spare fiber optic connection cables are plugged into the maintenance side of the upper layer area, and the connection terminals and the fiber optic connection cable 313 are respectively plugged into the incoming and outgoing line side and the maintenance side of the lower layer area.

[0115] The lower layer area is divided into an occupied area and a recycling area. The number of fiber optic ports in the occupied area is more than that in the recycling area. The recycling area and the occupied area are distributed left and right. The connection terminals and the fiber optic connection cable 313 are respectively plugged into the incoming and outgoing line side and the maintenance side of the usage area 200.

[0116] The fiber optic ports arranged in an array are adjacent to each other in the left - right direction to form rows, and are separated in the up - down direction, forming a walking space for the manipulator to pass through between rows;

[0117] On the maintenance side, a storage area 100 is arranged on the left side of the distribution board, and a use area 200 is arranged on the right side. The optical fiber line 300 of the spare optical fiber connecting line extends leftward and is stored in the storage area 100, and the optical fiber line 300 of the used optical fiber connecting line 313 extends rightward and is stored in the use area 200.

[0118] In this embodiment, the fiber optic distribution robot adopts a modular structure and a semi - open design, which is simple and convenient for maintenance. When a hardware device failure occurs in the robot, the key components of the station - end control host, manipulator, and stepping motor can be disassembled, replaced, and repaired. Moreover, since the fiber - jumping logic is the same as that of the traditional ODF, during the equipment failure period, the operation and maintenance personnel can open the back of the cabinet and take over the robot with manual operation. Compared with the "black - box" - type structure design of similar products, it can avoid a large number of optical path adjustment and cut - over operations during equipment repair.

[0119] The manipulator of this embodiment includes a clamping part for clamping the first terminal 110 or the second terminal 120, and a passing part located behind the clamping part and capable of accommodating the optical fiber line 300 to pass through therein. The clamping part can be opened to allow the optical fiber line 300 to enter the passing part, and closed to restrict the optical fiber line 300 within the passing part; the motion device further includes a telescopic mechanism for controlling the forward and backward movement of the manipulator. The telescopic mechanism controls the manipulator to move forward and backward relative to the distribution board with multiple - stage telescopic freedom degrees. The multiple - stage telescopic freedom degrees at least include a first position away from the distribution board to ensure that the manipulator and the optical fiber connecting line it holds 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 into the fiber optic port to allow the optical fiber line 300 to enter the passing part, and a third position close to the rear end of the first terminal 110 or the second terminal 120 inserted into the fiber optic port to allow the clamping part to clamp the first terminal 110 or the second terminal 120;

[0120] The motion device further includes a rotating mechanism for controlling the rotation of the manipulator. When the manipulator moves the optical fiber line 300 in translation, the passing part is maintained as a through - hole penetrating left - right; during the process of releasing the optical fiber line 300, the rotating mechanism drives the manipulator to rotate until the passing part becomes a through - hole penetrating up - down.

[0121] In this embodiment, first, the clamping part is opened, and the mechanical arm moves forward to make the optical fiber wire 300 enter the through - part; then the clamping part is closed, and the mechanical arm grabs the optical fiber wire 300 in the through - hole formed in the through - part. The optical fiber wire 300 is moved to the front of the storage area 100 by moving the mechanical arm; finally, the mechanical arm is rotated by the rotating mechanism, so that the optical fiber wire 300 is intercepted in the storage area 100, and the optical fiber wire 300 is driven again until it reaches the beam - splitting area and then the optical fiber wire 300 is released.

[0122] The storage area 100 includes a plurality of vertically arranged vertical areas separated by several vertical partitions. The first terminals 110 and the second terminals 120 of each spare optical fiber connection wire are connected to two adjacent optical fiber ports on the left and right. All spare optical fiber connection wires occupy several rows of optical fiber ports. Each vertical area of the storage area 100 is used to store the optical fiber wire 300 of the spare optical fiber connection wire connected to the continuous multiple rows of optical fiber ports. The row of optical fiber ports corresponding to the spare optical fiber connection wire to which the optical fiber wire 300 stored in the vertical area close to the wiring board is connected is lower than the row of optical fiber ports corresponding to the spare optical fiber connection wire to which the optical fiber wire 300 stored in the vertical area far from the wiring board is connected.

[0123] An upward hook is provided at the upper part of the right partition of each vertical area, and each hook corresponds to a row of optical fiber ports.

[0124] A notch is provided in the middle of the right partition of each vertical area, and a baffle extending from the left partition to the right partition is provided at the position of the left partition corresponding to the notch. There is a gap between the baffle and the notch, which is used to allow the optical fiber wire 300 to move out of the storage area 100.

[0125] A sorting area is also provided between the use area 200 and the wiring board, and a beam - splitting area is also provided above the use area 200.

[0126] The sorting area includes a first substrate 410 and a second substrate 420 distributed vertically and parallel to each other. The first substrate 410 and the second substrate 420 include a plurality of downward hooks, and each hook corresponds to a row of optical fiber ports. An elastic seal 430 is provided between the first substrate 410 and the second substrate 420. The first substrate 410 and the second substrate 420 are staggered in the vertical direction, so that the elastic seal 430 can completely seal the gap between two adjacent hooks of the first substrate 410 and cannot completely seal the gap between two adjacent hooks of the second substrate 420.

[0127] The beam - splitting area includes a plurality of supporting members arranged vertically with different heights, and each supporting member corresponds to storing the optical fiber wire 300 of continuous multiple rows of optical fiber ports.

[0128] The sorting area includes two layers of limiting layers in the front - to - back direction. Each layer of limiting layer includes a plurality of elastic cantilever rods distributed at intervals in the up - and - down direction.

[0129] In this embodiment, multiple bundles of optical fiber lines 300 are sequentially arranged and placed in the vertical area. The fiber ports corresponding to each hook buckle enable the organized optical fiber lines 300 to be separated nearby when detached from the wire harness. The notch in each vertical area allows the optical fiber lines 300 to be temporarily separated between the two baffles, preventing entanglement of the optical fiber lines 300 when the terminal is pulled out and the optical fiber line 300 is inserted into the fiber port during subsequent steps. In this embodiment, the organizing area is used for storing and organizing the optical fiber lines 300 after fiber optic jumpers are completed. The beam splitting area is used for the initial storage state of the optical fiber line bundles 300. The first substrate 410 can prevent the optical fiber lines 300 from accidentally entering.

[0130] In this embodiment, the elastic seal 430 is placed between the first substrate 410 and the second substrate 420. The side surfaces are fitted to the inner walls of the first substrate 410 and the second substrate 420. The hook buckle gaps on the first substrate 410 are blocked by the side surfaces of the elastic seal 430, preventing optical fiber lines 300 other than those grabbed by the manipulator from accidentally entering between the two substrates. There is a gap between the hook buckle gap on the second substrate 420 and the side surface of the elastic seal 430, enabling the optical fiber lines 300 in the passing portion to automatically slide along the hypotenuse into the gap after the manipulator presses the elastic seal 430. When the manipulator disengages from the elastic seal 430 and rotates upward, the optical fiber lines 300 in the passing portion are intercepted in the hook buckle gap of the second substrate 420, so that when the manipulator continues to move the optical fiber lines 300 on the storage area 100, the optical fiber lines 300 and the hook buckles of the second substrate 420 form a fulcrum.
