However, the operation and maintenance of the power optical cable network still relies on manual maintenance and lacks the support of automated operation and maintenance technology, which has become a key shortcoming in operation and maintenance efficiency.

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

[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 greater than that in the recovery area. The recovery area and the occupied area are distributed on the left and right. The used 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.

[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 row 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 wiring board is lower than the row 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 wiring 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 part 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 on 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; through the height of the optical fiber port row, when the robot moves the optical fiber out of the storage area on the left side of the wiring board, the latter movement trajectory can be less than the previous movement trajectory; through the corresponding notches and hooks, the efficiency of optical fiber organization in the vertical and horizontal directions is enhanced.

[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 spacing 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 spacing 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, so as to prevent the optical fiber from accidentally falling, and to guide the optical fiber to slide along the oblique edge to the gap between the hooks of the second substrate when squeezed, so as to achieve the effect that the robot drives the optical fiber to squeeze the serrated sponge, enter between the first substrate and the second substrate, rotate the passing part and release 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 the communication devices. When a disconnection occurs between two communication devices that have been connected by using optical fibers and optical fiber connection cables, the control platform automatically starts a manipulator to restore the connection between the two communication devices by the following method, which specifically includes the following steps:

[0021] S0 removes the optical fiber connection line used to connect the two communication devices, disconnects the two communication devices, selects the optical fiber port connected to the backup optical fiber of one communication device as the first optical fiber port, and the optical fiber port connected to the backup optical fiber of the other communication device as the second optical fiber port, and the number of the first optical fiber port is smaller than that of the second optical fiber port;

[0022] S1 selects a spare optical fiber splicing line, moves the manipulator horizontally to the rear of the first terminal, restricts the optical fiber line in the passing portion from the rear of the first terminal, and moves the manipulator horizontally from top to bottom to move a part of the optical fiber line out of the storage area to release the optical fiber line;

[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 travel 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 part of the optical fiber in the use area, and releases the optical fiber;

[0025] S4: The manipulator is moved horizontally to the rear of the second terminal of the spare optical fiber connection line, and the optical fiber line is confined in the passing portion from the rear of the second terminal, and the manipulator is moved horizontally from top to bottom to move the remaining part of the optical fiber line out of the storage area, thereby releasing the optical fiber line;

[0026] S5: The manipulator moves horizontally to the rear of the second terminal, clamps the second terminal and pulls it out of the idle optical fiber port, the manipulator clamps 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: starting from the rear of the second terminal, the optical fiber is confined in the running portion, the manipulator is translated from bottom to top to the use area, and the manipulator is translated 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 change the fiber optic patch cord to a spare fiber optic patch cord through remote operation of the manipulator. According to the design of multiple fiber optic ports on the fiber optic patch terminal, each step of the manipulator on the fiber optic cable, including release, grasping, plugging and unplugging, and storage, is more efficient and accurate.

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

[0031] S01: The manipulator is translated to the rear of the first terminal, and the optical fiber is confined in the passing portion from the rear of the first terminal, and the manipulator is translated to move a part of the optical fiber out of the use area to release the optical fiber;

[0032] S02: The manipulator is translated to the rear of the first terminal, the first terminal is clamped and pulled out from the first optical fiber port, the manipulator is translated to an idle optical fiber port in the recovery area with the first terminal clamped, the first terminal is inserted into the optical fiber port, and the first terminal is released;

[0033] S03 starts from the rear of the first terminal to confine the optical fiber in the travel 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 translated to the rear of the second terminal, the optical fiber is confined in the passing portion from the rear of the second terminal, the manipulator is translated to move the remaining part of the optical fiber out of the use area, and the optical fiber is released;

[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 make the contact process between the manipulator and the optical fiber more specific, improve the accuracy of the manipulator's control, and the optical fiber is pulled through and released to a specific position, making the arrangement and storage of the optical fiber more efficient, which is convenient for the next operation of the manipulator.

[0038] Furthermore, the manipulator also has a multi-stage telescopic freedom of advancing and retreating relative to the wiring board, and the multi-stage telescopic freedom at least includes a first position away from the wiring board to ensure that the manipulator and the optical fiber splicing line it clamps will not interfere with other components during translation, a second position close to the rear end of the first terminal or the second terminal plugged into the optical fiber port so that the optical fiber can enter the passing part, and a third position close to the rear end of the first terminal or the second terminal plugged into the optical fiber port so that the clamping part can clamp the first terminal or the second terminal; the first terminal and the second terminal of the spare optical fiber splicing line are respectively plugged into two parallel idle optical fiber ports, and the optical fiber starts from the first terminal and enters the storage area from top to bottom, and then goes out of the storage area from bottom to top to the second terminal after winding in the storage area;

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

[0040] When the optical fiber is confined in the passing portion, the robot is translated to the right to a position between two substrates of the corresponding hook;

[0041] The manipulator moves forward to the third position, squeezes the elastic plug 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, translates to the right side of the second substrate, advances to the third position, and translates 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 is translated from bottom to top, driving the optical fiber line to the beam splitting area, and the manipulator moves forward to the second position, crossing 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 line 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 be stored in front of the front limiting layer.

[0046] It is beneficial to keep the optical fiber line neat and orderly on the optical connection line terminal when the manipulator 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 by 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 by the front and rear limiting layers, so as to improve the storage neatness and efficiency.

[0047] Compared with the prior art, 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 robot, the cable fiber jumping 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 input, 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.

Example 1

[0059] like Figure 1-9As shown, the present 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 disconnection occurs; the optical fiber connection terminal includes: a patch panel, on which optical fiber ports arranged in a matrix are provided, and the optical fiber ports extend from one side of the patch panel to the other side, and the communication device includes a working optical fiber and at least one spare optical fiber, and 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 of which has a first terminal 110 and a second terminal 120 at both ends, respectively, and is connected by an optical fiber line 300 of a certain length, wherein some of the 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 part of the optical fiber splicing line is a spare optical fiber splicing line, and its first terminal 110 and the second terminal 120 are respectively plugged into the optical fiber port on the other side that is not used on one side; the storage area 100 on the left side and the use area 200 on the right side of the wiring board, the optical fiber line 300 of the spare optical fiber splicing line is stored in the storage area 100, and the optical fiber line 300 of the use optical fiber splicing line is stored in the use area 200; the manipulator, the manipulator is remotely controlled by the control platform, has the degree of freedom of translation along the up, down, left and right directions, includes a clamping part for clamping the first terminal 110 or the second terminal 120, and a running part located behind the clamping part and capable of accommodating the optical fiber line 300 to pass therethrough, the clamping part can be opened to allow the optical fiber line 300 to enter the running part, and closed to confine the optical fiber line 300 to the running part;

[0060] 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 number increases gradually 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.

[0061] 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 the first optical fiber port 130, pull out the second terminal 120, and insert the second optical fiber port 140.

[0062] In this embodiment, the control platform is the main station system, and the optical fiber line 300 connection terminal is a station-end device, wherein the main station system is installed in the communication room of the ground control center, including servers, workstations, switches, firewalls, encryption gateways and other equipment, and the station-end optical cable routing, fiber core resources, and data management of the carrying business information are realized through the management platform software, and the instructions can be transmitted 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 the existing optical fiber distribution equipment respectively, and can receive the main station instructions to realize automatic switching between optical paths. The specific functions include executing the main station instructions to complete the fiber jumper plugging and unplugging between different ports, and realizing the designated port optical path test through the embedded OTDR, light source and optical power meter. Optical equipment includes SDH equipment, ASON equipment, OTN equipment, data network equipment, and protection equipment.

[0063] 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; 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 pixel ≥3MP, and can trace back actions; fourth, it has anti-entanglement and physical dustproof functions for fiber jumper, and the optical fiber interface is compatible with dust cap coverage.

[0064] In this embodiment, software and hardware are combined to prevent the occurrence of remote misoperation of optical fiber wiring, or to provide a mechanism for timely error correction 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 jump operation, and the system can automatically determine the receiving and transmitting optical ports (TX to RX) when jumping with the optical module. If the optical module TX to TX is manually connected, the software has an automatic error correction reminder function, so that the "optical path adjustment" command cannot be issued; when performing automatic testing of the light source or OTDR, the software first checks whether the opposite optical device is disconnected to prevent the test light source from damaging the opposite optical device; for other artificial fiber jump operation errors and the command has just been issued, when it is found that error correction is needed, by adding a "pause" or "stop" function to the main station platform management software, the next error instruction is prevented from continuing to be issued.

[0065] 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 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 in the optical fiber port to enable 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 in the optical fiber port to enable the clamping part to clamp the first terminal 110 or the second terminal 120.

[0066] In this embodiment, in terms of hardware structure design, the following measures are taken to prevent the manipulator from erroneous movements. First, a gantry with a combination of precision guide rails is used to first achieve precise positioning of the X and Y axis coordinates, and then the Z axis with a high-precision stepper motor is used to accurately position the manipulator, thereby achieving high-precision positioning of the three-dimensional coordinates; second, a feedback circuit with a high-precision encoder is used to achieve a stable and firm gripping force of the manipulator to prevent the manipulator from being loose and unable to hold the optical fiber plug tightly; third, a high-precision MU socket with a 0.1mm pitch is used to prevent mis-insertion of the port and reduce insertion loss; fourth, a 5MP pixel high-definition camera is installed on the manipulator to remotely monitor the movement of the equipment in real time, and provide video playback and tracing of historical operation processes.

[0067] The manipulator also has a rotational freedom about a certain axis of its own, a V-shaped elastic mechanism is provided in the passage portion for supporting the optical fiber line 300, and the storage area 100 and the use area 200 are provided with a release assistance mechanism; when the manipulator drives the optical fiber line 300 to translate, the passage portion is maintained as a through hole that passes through the left and right; in the process of releasing the optical fiber line 300, the passage portion is rotated until it becomes a through hole that passes through the top and bottom.

[0068] In this embodiment, when the V-shaped elastic mechanism is opened, the manipulator moves forward to allow the optical fiber line 300 to enter the passage portion, and when the V-shaped elastic mechanism is closed, the manipulator grabs the optical fiber line 300 in the through hole formed in the passage portion, and the manipulator can control the release direction of the optical fiber line 300 by rotating. The release assisting mechanism is used to intercept the optical fiber line 300 that is taken out of the wire bundle in the storage area 100.

[0069] 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 fiber and the spare optical fiber 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.

[0070] 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.

[0071] 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 spare fiber cores of the station-end optical cable, can automatically upload test data and documents to the management platform, and will prompt operators for defect data that exceeds the set value.

[0072] One of them is the automatic test of fiber core attenuation value. During the pre-set service idle time period (except when the equipment is adjusting the optical path operation), the system automatically sends the spare fiber cores that have been connected between the two stations. After the manipulators at both ends align the two ends of the fiber core to be tested, the embedded light source optical power is enabled, and the overall attenuation data of the optical fiber core is read after the automatic test. After each fiber core is tested, the device automatically uploads the attenuation value of the optical core, and automatically calculates the average attenuation data per kilometer, and automatically sends the test and calculation results to the main station management platform server for storage.

[0073] The second is the automatic detection of the optical fiber breakpoint location. The main station management platform sends an OTDR command, and the station-side manipulator docks one end of the optical fiber core to be tested and activates the OTDR instrument. After automatic testing, the image and event document of the optical fiber core test event are realized, and the data of the optical core is automatically reported to the main station management platform server.

[0074] 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 in 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.

[0075] The storage area 100 includes a plurality of vertical areas arranged left and right divided by a plurality of vertical partitions. The first terminal 110 and the second terminal 120 of each spare optical fiber splicing line are connected to two adjacent optical fiber ports on the left and right. All spare optical fiber splicing lines 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 splicing lines connected to a plurality of consecutive rows of optical fiber ports. The row of optical fiber ports connected to the spare optical fiber splicing lines corresponding to the optical fiber lines 300 stored in the vertical area close to the wiring board is lower than the row of optical fiber ports connected to the spare optical fiber splicing lines 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 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 part 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.

[0076] In this embodiment, the vertical area arranges and places multiple bundles of optical fiber lines 300 in sequence, and the optical fiber port 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 two baffles to avoid entanglement of the optical fiber line 300 when the terminal is pulled out and the optical fiber port is inserted in the subsequent steps.

[0077] 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 that are vertically and parallelly distributed, 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, 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 up and down at different heights, 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 up and down.

[0078] In this embodiment, the tidying 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

[0079] 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, whose 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.

[0080] 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, and 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 into the gap along the oblique edge, 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.

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;
