Description

Technical Field

[0001] This invention relates to the field of optical cable installation and testing technology, specifically to a laying and testing device for optical cable installation that is easy to maintain. Background Technology

[0002] Optical fiber cable is a communication cable assembly that uses one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. It mainly consists of optical fibers, a plastic protective sheath, and a plastic outer jacket. Optical signals are transmitted through the optical fibers. Currently, optical cables are primarily laid underground in conduits. However, the narrow conduits do not allow for operator access inside, necessitating the use of installation ropes during installation. This method not only limits the laying method and distance but also makes subsequent fiber inspection extremely difficult.

[0003] The existing patent document with publication number "CN119717189A" discloses an unmanned laying and testing device for optical cable installation. Although this device uses unmanned robots to lay and test optical cables located inside ducts, which can greatly reduce the difficulty of manual operation and the initial installation and subsequent testing and maintenance, this design has certain limitations. For different situations such as underground burial and high-altitude laying of optical cables, different equipment is required for laying and testing, which causes inconvenience. Therefore, we propose a laying and testing device and method for optical cable installation that is easy to maintain to solve the above problems. Summary of the Invention

[0028] The locking adjustment module includes a semi-transmission ring, a fourth spring, and an operating lever;

[0029] The semi-transmission rings are rotatably disposed in the two halves of the positioning ring sleeve. The semi-transmission rings can form a complete circular ring shape. The inner side of the semi-transmission rings has a protrusion. The end of the support frame inside the positioning ring sleeve can contact the protrusion.

[0030] A spring-loaded baffle is installed inside the semi-transmission ring, and a fourth spring is installed on the spring-loaded baffle to drive the semi-transmission ring to reset. The end of the fourth spring is installed on the positioning ring sleeve.

[0031] When the semi-transmission ring is in its initial state, one end of the semi-transmission ring extends out of the positioning ring sleeve.

[0032] The positioning ring sleeve has an operating groove corresponding to one side of the semi-transmission ring. An operating lever is installed on one side of the semi-transmission ring. The operating lever is slidably disposed in the operating groove and can be operated by personnel.

[0033] In a preferred embodiment of the present invention, the wire feeding unit includes a wire feeding frame, a wire feeding roller, a wire sleeve, and a lubricant reservoir.

[0034] The middle of the pay-off roller is rotatably positioned in the middle of the pay-off frame;

[0035] The wire sleeve is installed on one side of the wire feeding frame, and the optical cable is fed from the middle of the wire sleeve. The lubricant reservoir is installed at the bottom of the wire feeding frame and can communicate with the inside of the wire sleeve.

[0036] The inner side of the wire sleeve is fitted with a sponge inner layer that can be soaked in lubricant.

[0037] In a preferred embodiment of the present invention, the wire feeding frame is provided with an outlet pipe and an inlet pipe that are connected to the wire sleeve and the lubricating fluid storage tank, respectively.

[0038] The liquid outlet pipe and the liquid inlet pipe are connected from the center of the side of the feeder;

[0039] The center of both sides of the wire feeding frame is rotatably connected to a drive shaft wheel coaxial with the wire feeding roller. A linkage shaft is inserted through the middle of the wire feeding roller and the push blade. Both ends of the linkage shaft extend out of the wire feeding frame and are threadedly connected to a nut.

[0040] A pusher blade is installed on the outside of the drive shaft wheel, and a liquid supply valve plate that can unidirectionally close the connection between the liquid outlet pipe and the liquid inlet pipe is provided.

[0041] The liquid supply valve plate includes a positioning sealing plate, an opening and closing plate, a limiting slide, and a guide rod;

[0042] The positioning sealing plate is slidably connected at the connection between the liquid outlet pipe and the liquid inlet pipe. A guide rod is installed on the side of the positioning sealing plate near the liquid outlet pipe. The guide rod is slidably connected to the wire feeding frame. A first spring that can reset the positioning sealing plate is connected between the end of the guide rod and the wire feeding frame.

[0043] The positioning sealing plate has a through hole in the middle. A limiting slide is installed on the side of the positioning sealing plate near the liquid outlet pipe, which surrounds the through hole. An opening and closing plate that can seal the through hole is slidably arranged between the limiting slide and the through hole.

[0044] The pusher blade can rotate to push the positioning seal plate gradually towards the liquid outlet pipe, and gradually detaches from the positioning seal plate during the pushing process.

[0045] A method for using a fiber optic cable installation and testing device that is easy to maintain includes the following steps:

[0046] Step 1: Connect the traction hook to the traction head at the end of the optical cable to be laid. At this time, close the positioning ring and adjust the state of the self-expanding rod according to the specific usage requirements so that the self-expanding rod can be in a multi-directional support state or in a self-expanding rod end connection state, which is suitable for optical cable laying in ducts or at high altitudes.

[0047] Step 2: Driven by the drive ball, the laying detection unit moves forward to lay the optical cable and pulls the optical cable out of the conductor sleeve. When the optical cable is laid out, the laying roller rotates and drives the drive shaft wheel and the push blade to rotate, gradually driving the liquid supply valve plate to move towards the liquid outlet pipeline. Under the action of pressure difference, the lubricant is supplied to the conductor sleeve.

[0048] Step 3: Apply lubricant through the inner layer of the sponge to the outer side of the optical cable to reduce damage caused by friction during installation.

[0049] Step 4: After the optical cable is laid, the laying detection unit retracts. At this time, the electronic control detection module rotates during the retraction to detect the optical cable. After the detection is completed, the laying detection unit can be successfully removed by opening the positioning ring.

[0050] Step 5: When the laying and testing unit moves forward and backward, the air nozzles generate airflow to propel the unit. When moving forward, the air nozzles assist the laying and testing unit in advancing and cleaning the inside of the duct. When moving backward, the air nozzles clean the surface of the optical cable, which is beneficial for the testing of the optical cable.

[0051] Step Six: During the laying of the optical cable, the automatic beacon deployer generates precise geographical location information of the deployed optical cable and generates a unique ID for its maintenance point. During maintenance, if a section of the optical cable is interrupted, the maintenance personnel only need to enter the fault link information into the background management system, and the system will immediately highlight the fault segment on the electronic map and provide the distance and the ID of the nearest beacon point.

[0052] As a preferred embodiment of the present invention, wherein:

[0053] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0054] 1. This easy-to-maintain optical cable installation and testing device, through the rotation adjustment of the self-extension rod and the action of the drive ball, can be changed according to the specific usage conditions. It is applicable to the laying and testing of optical cables buried in high-altitude areas, pipelines, and trenches, thus making it more versatile.

[0055] 2. This easy-to-maintain fiber optic cable installation and laying detection device generates precise geographical location information of the deployed fiber optic cable through an automatic beacon deployer and generates a unique ID for its maintenance point. During maintenance, if a section of fiber optic cable is interrupted, maintenance personnel only need to input the fault link information into the background management system. The system will immediately highlight the fault segment on the electronic map and provide the distance and the ID of the nearest beacon point, thereby accurately locating the fault point and facilitating subsequent maintenance.

Detailed Implementation

[0073] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] Example: Figure 1-13 As shown, the present invention provides a fiber optic cable installation and laying detection device that is easy to maintain, including a cable laying unit 100 and a laying detection unit 200, the laying detection unit 200 including:

[0075] Central support frame 23;

[0076] Positioning rings 21 are respectively set at both ends of the central support frame 23. The positioning rings 21 are composed of two halves and can be opened and closed to form a closed loop. The middle of the inner side of the positioning rings 21 is rotatably set in the electronic control detection module 22. Multiple support wheel modules 28 and locking adjustment modules 29 that can drive the support wheel modules 28 to move adaptively are set at both ends of the inner side of the positioning rings 21.

[0077] The telescopic rods 24 are respectively hinged to the outside of the two halves of the positioning ring sleeve 21. The ends of the telescopic rods 24 are provided with driving balls 25, which can be spliced ​​together above the positioning ring sleeve 21.

[0078] One end of the central support frame 23 is equipped with a traction hook, which can be connected to the traction head of the end of the optical cable to be laid.

[0079] It should be noted that, in this embodiment, during the laying of the optical cable, by hanging the end of the optical cable to be laid on the traction hook, the self-extension rod 24 provides support in multiple directions, thus supporting the optical cable inside the duct and enabling the laying of the optical cable within the duct. When the self-extension rod 24 rotates and the driving ball 25 contacts the ground, the laying of the buried optical cable can be achieved. When the self-extension rod 24 rotates and the driving ball 25 aligns, the driving ball 25 is positioned directly above the optical cable and can contact the high-altitude work line. The self-extension rod 24 allows the laying detection unit 200 to be suspended at a high altitude. On the aerial work line, the high-altitude optical cable is laid. The rotation of the drive ball 25 enables the laying detection unit 200 to move. After the laying is completed, the laying detection unit 200 retracts to perform optical cable inspection, thus ensuring the quality of the optical cable laying. After the complete laying and inspection, the laying detection unit 200 can be removed by opening the positioning ring 21 for easy maintenance. In the later maintenance, the optical cable can be placed in the positioning ring 21 and the optical cable can be inspected by moving the laying detection unit 200, which facilitates the later maintenance work.

[0080] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that both ends of the central support frame 23 are equipped with end frames 26, the positioning ring sleeve 21 is connected to the end frame 26 by a shaft pin, and air blowing nozzles 27 are installed on the end of the central support frame 23 away from the traction hook and on the end frame 26 at this end.

[0081] When the traction hook moves forward, it can pull the optical cable to be laid; when it moves backward, it automatically disconnects from the optical cable to be laid.

[0082] It should be noted that in this embodiment, under the pneumatic push of the air blower 27, high-speed, high-flow dry air is generated. The high-speed airflow forms a Venturi effect in the pipe, generating a forward pulling force on the optical cable. This forms a "push-pull combination" with the drive ball 25, which greatly extends the single laying distance. Under the blowing of the air blower 27, the surface of the optical cable can be blown by the air, avoiding the dust adhering to the optical cable from affecting the detection accuracy of the electronic control detection module 22.

[0083] like Figure 1-13As shown, compared with the previous embodiment, the difference is that the central support frame 23 is equipped with an automatic beacon deployer, which generates the precise geographical location information of the deployed optical cable and generates a unique ID for its maintenance point.

[0084] It should be noted that in this embodiment, the automatic beacon deployer includes a GNSS positioning module, which acquires high-precision latitude and longitude coordinates in real time, continuously records the laying trajectory of the entire optical cable, and forms an electronic map. During maintenance, if a section of the optical cable is interrupted, maintenance personnel only need to input the fault link information into the background management system. The system will immediately highlight the faulty section on the electronic map and provide the distance and the ID of the nearest beacon point, thereby accurately locating the fault point. Although this increases the initial investment, it lays a solid foundation for the maintenance work throughout the entire optical cable life cycle, realizing the transformation from "passive response maintenance" to "predictable and precise maintenance", and significantly reducing the total life cycle cost.

[0085] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that an mounting ear plate 2101 is installed at the center of the outer side of the two halves of the positioning ring sleeve 21;

[0086] The self-extension rod 24 includes a fixed sleeve 2402, a sliding rod 2403, a contact notch 2404, and a second spring 2405;

[0087] One end of the fixed sleeve 2402 is hinged between the mounting ear plates 2101, and the pin of the fixed sleeve 2402 extends out of the mounting ear plate 2101 and is threaded with a nut 2401 that can abut against the mounting ear plate 2101. The sliding rod 2403 is slidably connected to the other end of the fixed sleeve 2402.

[0088] One end of the sliding rod 2403 extends into the fixed sleeve 2402 and is equipped with a second spring 2405. One end of the second spring 2405 is installed in the fixed sleeve 2402.

[0089] The other end of the sliding rod 2403 extends out of the fixed sleeve 2402, and the driving ball 25 is rolled at the end of the sliding rod 2403 that extends out of the fixed sleeve 2402;

[0090] The sliding rod 2403 has a contact notch 2404 on the side of the end of the fixed sleeve 2402 that exposes the driving ball 25.

[0091] It should be noted that in this embodiment, by turning the second nut 2401, the position of the fixed sleeve 2402 after rotation adjustment can be determined, realizing adaptive adjustment for optical cable laying scenarios. Under the elastic push of the second spring 2405, the fixed sleeve 2402 and the sliding rod 2403 can be relatively adaptively extended and retracted to adapt to different pipe diameters, thereby making it more convenient to use. By opening the contact notch 2404, the driving ball 25 can contact the high-altitude operation line, and then the rolling of the driving ball 25 can smoothly drive the laying detection unit 200 to move.

[0092] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that a second motor 2406 is provided inside the sliding rod 2403, and the output shaft of the second motor 2406 is connected to a drive wheel 2407. The drive wheel 2407 can contact the outer surface of the drive ball 25 to drive the laying detection unit 200 to move forward and backward.

[0093] The driving ball 25 includes a driving ball 2501, a connecting swivel block 2502, a connecting rod 2503, and a guide post 2504;

[0094] The connecting screw block 2502 is rotatably disposed on the outside of the driving ball 2501, and the connecting rod 2503 is threadedly connected to the inside of the connecting screw block 2502. The outer sides of the driving ball 2501, the connecting screw block 2502, and the connecting rod 2503 together form a complete spherical outer surface.

[0095] Inside the drive ball 2501, there is a guide post 2504 that is axially aligned with the connecting rod 2503. The guide post 2504 is slidably disposed inside the connecting rod 2503. The connecting rod 2503 inside another drive ball 25 can be screwed into the connecting block 2502.

[0096] It should be noted that, in this embodiment, under the drive of the output shaft of the second motor 2406, the drive wheel 2407 can rotate, which in turn allows the drive ball 25 to roll smoothly, thereby driving the laying detection unit 200 to move. The drive ball 25 has a spherical structure, and when the drive ball 25 is assembled, rotating the drive ball 25 allows the connecting rod 2503 to be aligned, so that the drive balls 25 can be connected.

[0097] When connecting the drive balls 25, the connecting block 2502 is rotated so that one connecting rod 2503 can move into the drive ball 2501, and the other connecting rod 2503 can move into the connecting block 2502 and be threadedly connected to it (note that at this time, one connecting rod 2503 is threadedly connected to both connecting blocks 2502), which ensures the connection between the drive balls 25 and avoids the risk that the laying detection unit 200 may fall from the high-altitude work line due to the gap between the drive balls 25.

[0098] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that the electronic control detection module 22 is composed of two halves that are adapted to the positioning ring sleeve 21. The electronic control detection module 22 is a closed-loop ring and is rotatably connected to the middle of the inner side of the positioning ring sleeve 21.

[0099] The positioning ring sleeve 21 has a transmission gear 2201 rotatably installed in both halves, and the electronic control detection module 22 has a semi-external toothed ring 2203 installed on the outer side of both halves. The semi-external toothed ring 2203 can form a complete toothed ring, and the transmission gear 2201 meshes with the semi-external toothed ring 2203.

[0100] The first motor 2202 is installed in both halves of the positioning ring sleeve 21, and the output shaft of the first motor 2202 is connected to the shaft of the transmission gear 2201.

[0101] It should be noted that in this embodiment, when the positioning ring 21 is open, the electronic control detection module 22 is also open. When the positioning ring 21 is closed, the positioning ring 21 can be inserted. Under the drive of the output shaft of the first motor 2202, the transmission gear 2201 can rotate, which in turn allows the semi-external toothed ring 2203 to rotate and drive the positioning ring 21 to rotate to detect the optical cable. By using a meshing method, the position of the positioning ring 21 can be limited.

[0102] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that the support wheel module 28 includes a support frame 2801, a limiting wheel 2802, and a third spring 2803;

[0103] The support frame 2801 is slidably connected to the inner side of the positioning ring sleeve 21, the limiting wheel 2802 is rotatably connected to the end of the support frame 2801 that extends out of the positioning ring sleeve 21, and the third spring 2803 is installed on both sides of the end of the support frame 2801 that is inside the positioning ring sleeve 21.

[0104] Locking adjustment module 29 includes a semi-transmission ring 2901, a fourth spring 2902, and an operating lever 2904;

[0105] The semi-drive rings 2901 are rotatably disposed in the two halves of the positioning ring sleeve 21. The semi-drive rings 2901 can form a complete ring shape. The inner side of the semi-drive rings 2901 has a protrusion 2903. The end of the support frame 2801 inside the positioning ring sleeve 21 can contact the protrusion 2903.

[0106] A spring-loaded baffle is installed on the inner side of the semi-transmission ring 2901. The spring-loaded baffle is equipped with a fourth spring 2902 that can drive the semi-transmission ring 2901 to reset. The end of the fourth spring 2902 is installed on the positioning ring sleeve 21.

[0107] When the semi-drive ring 2901 is in the initial state, one end of the semi-drive ring 2901 extends out of the positioning ring sleeve 21;

[0108] The positioning ring sleeve 21 has an operating groove 2102 corresponding to one side of the semi-transmission ring 2901. An operating lever 2904 is installed on one side of the semi-transmission ring 2901. The operating lever 2904 is slidably disposed in the operating groove 2102 and can be operated by personnel.

[0109] It should be noted that, in this embodiment, under the tension of the third spring 2803, the support frame 2801 is always in contact with the semi-transmission ring 2901. Supported by the support frame 2801 and the limiting wheel 2802, the optical cable is limited while maintaining a certain gap between the optical cable and the electronic control detection module 22, ensuring that the electronic control detection module 22 can perform complete detection of the optical cable. Driven by the protrusion 2903, the support frame 2801 extends out of the positioning ring sleeve 21, allowing for adjustable extension and retraction.

[0110] Note that when the semi-drive ring 2901 is in the initial state, one end of the semi-drive ring 2901 extends out of the positioning ring sleeve 21. At this time, the elastic force of the fourth spring 2902 is greater than the tension of the third spring 2803.

[0111] When closing the positioning ring sleeve 21, first pull the operating lever 2904 so that the operating lever 2904 is completely inside the positioning ring sleeve 21. Then, assemble the positioning ring sleeve 21 together. When releasing the operating lever 2904, under the elastic force of the fourth spring 2902, the half transmission ring 2901 can be simultaneously inside the two halves of the positioning ring sleeve 21, ensuring the stability of the connection of the positioning ring sleeve 21.

[0112] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that the wire feeding unit 100 includes a wire feeding frame 11, a wire feeding roller 12, a wire sleeve 13, and a lubricant reservoir 14;

[0113] The middle rotatable position of the pay-off roller 12 is located in the middle of the pay-off frame 11;

[0114] The wire sleeve 13 is installed on one side of the wire feeding frame 11, and the optical cable is fed from the middle of the wire sleeve 13. The lubricant reservoir 14 is installed at the bottom of the wire feeding frame 11 and can communicate with the inside of the wire sleeve 13.

[0115] The inner side of the wire sleeve 13 is fitted with a sponge inner layer that can be soaked in lubricant.

[0116] It should be noted that in this embodiment, when the wire feeding roller 12 is rotating and feeding the optical cable through the conductor sleeve 13, the lubricant in the lubricant reservoir 14 can be delivered to the inner sponge layer inside the conductor sleeve 13. The lubricant can be applied relatively evenly to the outer surface of the optical cable through the inner sponge layer. The lubricant can effectively reduce the friction of the optical cable and reduce the damage to the optical cable during laying.

[0117] like Figure 1-13 As shown, compared with the previous embodiment, the difference is that the wire feeding frame 11 is provided with an outlet pipe 101 and an inlet pipe 102 that are connected to the wire sleeve 13 and the lubricating fluid storage tank 14, respectively.

[0118] The liquid outlet pipe 101 and the liquid inlet pipe 102 are connected at the center of the side of the feeder 11;

[0119] The center of both sides of the wire feeding frame 11 is rotatably connected to a drive shaft wheel 16 coaxial with the wire feeding roller 12. A linkage shaft 15 is inserted through the middle of the wire feeding roller 12 and the push blade 19. The two ends of the linkage shaft 15 extend out of the wire feeding frame 11 and are threadedly connected to a nut.

[0120] A pusher blade 19 is installed on the outer side of the drive shaft wheel 16, and a liquid supply valve plate 17 that can unidirectionally close the connection between the liquid outlet pipe 101 and the liquid inlet pipe 102 is provided.

[0121] The liquid supply valve plate 17 includes a positioning sealing plate 171, an opening and closing plate 172, a limiting slide 173, and a guide rod 174;

[0122] The positioning sealing plate 171 is slidably connected at the connection between the liquid outlet pipe 101 and the liquid inlet pipe 102. A guide rod 174 is installed on the side of the positioning sealing plate 171 near the liquid outlet pipe 101. The guide rod 174 is slidably connected to the wire feeder 11. A first spring 18 is connected between the end of the guide rod 174 and the wire feeder 11 to reset the positioning sealing plate 171.

[0123] A through hole is provided in the middle of the positioning sealing plate 171. A limiting slide 173 is installed on the side of the positioning sealing plate 171 near the liquid outlet pipe 101 and surrounds the through hole. An opening and closing plate 172 that can seal the through hole is slidably arranged between the limiting slide 173 and the through hole.

[0124] The blade 19 can rotate to push the positioning seal plate 171 to move gradually toward the liquid outlet pipe 101, and gradually detaches from the positioning seal plate 171 during the pushing process.

[0125] It should be noted that, in this embodiment, when installing the pay-off roller 12, the pay-off roller 12 and the drive shaft wheel 16 are coaxial. At this time, the linkage shaft 15 is inserted, so that the linkage shaft 15 can be simultaneously inserted with the pay-off roller 12 and the drive shaft wheel 16. The linkage shaft 15 is stably installed on the pay-off frame 11 by using a nut. Simultaneously, by adjusting the tightness of the nut, the linkage shaft 15 can rotate. When the pay-off roller 12 pays off the wire, the drive shaft wheel 16 rotates together with the pay-off roller 12 through the transmission of the linkage shaft 15. The pusher blade 19 rotates, causing the positioning sealing plate 171 to gradually move towards the liquid outlet pipe 101. At this time, the positioning sealing plate 171 and the opening and closing plate 172 can complete the seal, pushing the lubricant into the liquid outlet pipe 101. When the pusher blade 19 disengages from the positioning sealing plate 171, the positioning sealing plate 171 can be reset under the action of the first spring 18. When the positioning sealing plate 171 is reset, the opening and closing plate 172 opens the through hole, forming a "suction" form to supply the lubricant.

[0126] A method for using a fiber optic cable installation and testing device that is easy to maintain includes the following steps:

[0127] Step 1: Connect the traction hook to the traction head at the end of the optical cable to be laid. At this time, close the positioning ring 21. Adjust the state of the self-extension rod 24 according to the specific usage requirements so that the self-extension rod 24 can be in a multi-directional support state or in a state of connection at the end of the self-extension rod 24, which is suitable for optical cable laying in ducts or at high altitudes.

[0128] Step 2: Driven by the drive ball 25, the laying detection unit 200 moves forward to lay the optical cable and pulls the optical cable out of the conductor sleeve 13. When the optical cable is laid out, the laying roller 12 rotates and drives the transmission shaft wheel 16 and the push blade 19 to rotate, gradually driving the liquid supply valve plate 17 to move towards the liquid outlet pipe 101. Under the action of pressure difference, the lubricant is supplied to the conductor sleeve 13.

[0129] Step 3: Apply lubricant through the inner layer of the sponge to the outer side of the optical cable to reduce damage caused by friction during installation.

[0130] Step 4: After the optical cable is laid, the laying detection unit 200 retracts. At this time, the electronic control detection module 22 rotates during the retraction to detect the optical cable. After the detection is completed, the laying detection unit 200 can be successfully removed by opening the positioning ring 21.

[0131] Step 5: When the laying and testing unit 200 moves forward and backward, the air nozzle 27 generates airflow to propel the air. When moving forward, it assists the laying and testing unit 200 in moving forward and cleans the inside of the pipe with air. When moving backward, it cleans the surface of the optical cable with air, which is beneficial for the testing of the optical cable.

[0132] Step Six: During the laying of the optical cable, the automatic beacon deployer generates precise geographical location information of the deployed optical cable and generates a unique ID for its maintenance point. During maintenance, if a section of the optical cable is interrupted, the maintenance personnel only need to enter the fault link information into the background management system, and the system will immediately highlight the fault segment on the electronic map and provide the distance and the ID of the nearest beacon point.

[0133] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
