Description

TECHNICAL FIELD

[0001] The application relates to an ADSS optical cable management method based on unmanned aerial vehicle inspection and classification protection, and belongs to the technical field of optical cable management. BACKGROUND

[0002] ADSS optical cable (all-dielectric self-supporting optical cable) is erected along the power line, laid under the high-voltage cable and kept at a safe live distance, and is one of the main power communication optical cable types at present, has the advantages of easy construction and non-power-off operation, but since the ADSS optical cable does not contain metal materials and is in a strong electric field environment, there is a high failure rate during its operation. Common ADSS optical cable failures include external damage (caused by construction, weather, and bird pecking), and electric corrosion. Among them, bird pecking and electric corrosion failures often occur at the contact position of the ADSS optical cable pre-stranded wire and the optical cable, which can cause damage or even breakage of the optical cable, and seriously affect the safe and stable operation of the power communication network.

[0003] However, the existing ADSS optical cable failure inspection method mainly relies on manual tower climbing inspection, which needs to climb to the ADSS optical cable hanging point and observe from the side of the tower to the optical cable, and has the disadvantages of low inspection efficiency, limited observation angle, low observation accuracy, poor work safety and the like.

[0004] Among them, ADSS optical cable failures mainly occur at the optical cable pre-stranded wire, and the main failure types of this part are bird pecking and electric corrosion. The current prevention and treatment of bird pecking failure of optical cable mainly relies on methods such as installing bird repellers and winding insulating waterproof tapes, and the prevention and treatment of electric corrosion failure of optical cable mainly relies on methods such as winding anti-electric corrosion tapes and coating RTV paint on the surface of the optical cable. The above-mentioned methods need to be regularly treated for the optical cable that may fail, and frequent tower climbing operations are required, which has the disadvantages of high danger, high cost and low efficiency. Through practice, the above-mentioned methods cannot completely eliminate the occurrence of ADSS optical cable bird pecking and electric corrosion failures, and have the disadvantage of poor effect.

[0005] The utility model patent "Bird damage prevention power ADSS optical cable protective sleeve structure" (CN215067458U) invents an optical cable protective sleeve applied to an ADSS optical cable line, the protective sleeve adopts a bird damage prevention power optical cable protective sleeve structure, reinforces the optical cable shell near the iron tower part, and effectively reduces the risk of ADSS optical cable being pecked by birds. The patent studies the bird pecking position, but does not consider the size difference of the optical cable and the optical cable shock absorber, has poor universality and is difficult to adapt to various types of optical cables. At the same time, the patent needs to be operated in high altitude, which is difficult and dangerous, and has safety hazards. In addition, the sleeve is designed for bird pecking failure and does not consider the anti-electric corrosion condition.

[0006] Therefore, there is an urgent need for an ADSS optical cable management method. SUMMARY

[0022] The embodiments of the present invention will be further described below with reference to the accompanying drawings: Example 1: As Figure 1 As shown, this invention provides an ADSS optical cable management method based on UAV inspection and classified protection, including the following steps: S1. Develop an inspection plan; Among them, the inspection of optical cables based on drones mainly involves inspecting the optical cable body, optical cable hardware, optical cable connection points, the external environment where the optical cable is located, and optical cable accessories (excess cable clamps, junction boxes, etc.).

[0023] During the inspection process, key areas and obvious defects are checked in real time, and any problems are reported and dealt with promptly.

[0024] On the other hand, standardized photography of the fixed locations of optical cables is conducted, and in-depth hazard investigations are carried out based on the photographs.

[0025] S2. Use drones to replace traditional manual labor for close-range, all-round inspections and to acquire ADSS optical cable image information; The close-range, all-round inspection includes every optical cable that needs to be inspected; the acquired ADSS optical cable images mainly involve basic information of the optical cable and major faults, and 13 types of standardized photos are taken from multiple parts and multiple angles.

[0026] The 13 types of photos include: (1) tower identification signs, (2) optical cable slack racks, (3) optical cable splice boxes, (4) optical cable downlead clamps, (5) optical cable fixing clamps, (6) optical cable hanging rings, (7) optical cable tension outer strands, (8) optical cable inner strands, (9) the junction of optical cable pre-twisted strands and optical cable, (10) optical cable anti-vibration whips, (11) optical cable anti-vibration hammers, (12) optical cable hanging points, and (13) optical cable crossing conditions.

[0027] S3. After acquiring the optical cable image, establish an optical cable ledger and check for any faults; The optical cable ledger is used for basic information inquiry, optical cable inspection plan formulation, optical cable defect handling basis, and optical cable protection plan formulation.

[0028] The optical cable basic ledger is created in the form of an electronic spreadsheet. Each column in the spreadsheet represents a type of optical cable information, and each row in the spreadsheet represents an optical cable inspection point.

[0029] The fiber optic cable information in the ledger includes: (Column A) the line to which the fiber optic cable belongs, (Column B) the tower number to which the fiber optic cable inspection point belongs, (Column C) the latitude and longitude of the fiber optic cable inspection point, (Column D) whether there is a fiber optic cable junction box, (Column E) the span of the fiber optic cable, (Column F) the crossing status of the fiber optic cable, (Column G) the type of potential fault of the fiber optic cable, (Column H) the type of the last fault of the fiber optic cable, (Column I) the time of the last fault of the fiber optic cable, (Column J) the time of the last inspection of the fiber optic cable, (Column K) the type of protection implemented for the fiber optic cable, (Column L) the time of the last implementation of fault protection measures for the fiber optic cable, and (Column M) the urgency of the fiber optic cable defect.

[0030] The fault types in columns G and H include: a) electrical corrosion, b) bird pecking, c) external force damage, d) junction box failure, e) missing optical cable fittings, f) optical cable wear, g) missing shockproof components, and h) spare cable rack failure.

[0031] The optical cable protection types in column K include: i) optimizing optical cable hanging points, ii) adding optical cable sleeves, iii) spraying insulating coating, iv) applying RTV coating, v) wrapping insulating tape, vi) replacing optical cables, vii) adding bird deterrents, viiii) applying red coating, ix) handling hardware failures, x) handling junction box failures, xi) handling shockproof device failures, and xii) handling excess cable rack failures.

[0032] The urgency levels of the defects in the M-series cables are categorized as: a) no risk, b) minor, c) moderate, and d) urgent.

[0033] S4. If a fault exists, the optical cable faults shall be investigated and classified item by item. Among these, it is necessary to clearly identify optical cable faults and classify the urgency of fault elimination, and to clarify the order of optical cable fault handling. S5. After classification, take corresponding protective measures for the identified optical cable faults and update the ledger; Among them, the corresponding protective measures are selected based on the basic information of the optical cable, the type of optical cable fault, and the urgency of the defect. S6. If there is no fault, update the ledger directly; Update the information in each column of the ledger as an important basis for subsequent work.

[0034] S7. Based on the updated ledger, formulate fault handling, inspection plans and protection schemes.

[0035] When handling faults, the M column in the ledger is sorted as the primary key and the G column as the secondary key. Defects with high urgency are dealt with first. After the faults are handled, the H, I, and M columns are updated. When formulating the inspection plan, the J column in the ledger is used as the main key for sorting, and priority is given to inspecting optical cable sections with long inspection intervals. After the inspection is completed, the relevant information in the J column is updated. When developing protection plans, they are implemented according to the classification of potential optical cable faults recorded in column G of the ledger.

[0036] Specifically, such as Figure 2 As shown, when the potential fault is electro-corrosion, if the fault location is within the range that can be manually handled and the mounting point can be changed, the solution is to optimize the mounting point based on the electric field strength distribution. If the mounting point cannot be changed, protection is provided by adding optical cable sheaths and wrapping with insulating tape. When the fault location is outside the range that can be manually handled, a special device must be used to spray insulating coating on the corresponding location.

[0037] If the fault is caused by bird pecking, and the fault location is within the range that can be handled manually, and the fiber optic cable can be replaced, then the existing fiber optic cable should be replaced with a bird-proof fiber optic cable. If the fiber optic cable cannot be replaced, protective measures such as installing fiber optic cable sheaths, installing bird deterrents, painting with red paint, and wrapping with insulating tape can be taken. When the fault location is outside the range that can be handled manually, a special device should be used to spray brightly colored insulating paint on the corresponding location to repel and prevent birds.

[0038] When the potential fault is caused by external damage, protective measures should be taken, such as increasing the inspection cycle, setting up optical cable identification signs, and strengthening publicity on optical cable protection.

[0039] If the potential fault is a junction box malfunction, replace the junction box if it is damaged, or reinforce the junction box if it is not properly secured.

[0040] When the potential fault is a problem with the optical cable fittings, if the problem is that the optical cable fittings are missing, then the corresponding optical cable fittings should be installed; if the optical cable fittings are damaged and can be repaired, then the fittings should be repaired; if the optical cable fittings cannot be repaired, then the optical cable fittings should be replaced.

[0041] If the potential fault is fiber optic cable wear, and the cable sling point can be changed, then the sling point should be optimized to prevent wear with the pole; if the cable sling point cannot be changed, then protective measures such as adding anti-wear buffers and wrapping with protective tape should be adopted.

[0042] When the potential malfunction is due to the absence of anti-vibration components, the solution is to install anti-vibration hammers and anti-vibration whips.

[0043] When the potential fault is a problem with the cable tray, if the cable is not properly secured, the cable binding should be reinforced in a standardized manner; if the cable tray is missing, it needs to be installed.
