Description

Technical Field

[0001] This invention relates to the field of electrical safety tool detection and early warning technology, and more specifically, to an intelligent early warning system for insulating rods based on defect levels. Background Technology

[0002] Insulating rods are safety tools used in power maintenance, distribution operation and maintenance, and live-line work. They typically include an insulating rod body, an end working head connector, a metal sleeve or adhesive transition section, inter-section connectors, hand guards and limiting devices, a handhold area, and a tail end sealing device. During use, turnover, storage, periodic inspection, and return to the warehouse, insulating rods may develop cracks, scratches, gaps, contamination, misaligned connections, localized moisture, abnormal equivalent insulation response, abnormal local leakage current, or abnormal partial discharge.

[0003] Existing testing or management systems for insulating tools typically perform identification, visual inspection, insulation performance testing, partial discharge detection, anomaly recording, or retrieval status management. However, the test results are mostly presented as overall pole conclusions, individual anomaly records, or coarse functional area alarms. Although the overall length of an insulating pole is finite and its structural composition is relatively clear, the end working head connection area, metal sleeve or adhesive bonding transition area, inter-section connection area, and handguard limit area correspond to connection, transition, force transmission, or operation limit positions, respectively. When the same structural defect or insulation anomaly occurs in different axial functional areas, the impact on retrieval safety varies. Cracks, contamination, moisture, leakage current anomalies, and partial discharge anomalies may also have localized and circumferential distribution characteristics.

[0004] The existing system lacks a unified spatial positioning basis defined by axial functional areas, axial sampling windows, and circumferential sectors. This makes it difficult to determine whether structural inspection results and insulation anomaly inspection results correspond to the same local defect area, and also makes it difficult to return to the same or adjacent locations during verification. Detection results that meet insulation anomaly conditions may not be spatially correlated with structural defects. If they are only treated as ordinary anomaly records or whole-pole alarms, there is a lack of continuously updated verification status, defect level, and status control objects, which can easily lead to a disconnect between verification, restricted access, disabling lockout, or release control.

[0005] Therefore, there is a need in this field for an intelligent early warning system for insulating rods that can uniformly link structural inspection results, insulation anomaly inspection results, verification results, and usage status control to the same local defect object. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, this invention provides an intelligent early warning system for insulating rods based on defect levels. This system uses spatial positioning tags to transform structural inspection results and insulation anomaly inspection results into structural defect objects, fused defect objects, or insulation anomaly verification objects. It also updates the defect level identifier and status control instructions based on the verification status, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An intelligent early warning system for insulated rods based on defect levels includes a detection unit, a safety monitoring center, and a tool status execution unit. The detection unit outputs structural inspection results, insulation anomaly detection results, and corresponding axial displacement and circumferential angle information. The safety monitoring center retrieves rod type parameters based on the insulated rod's identification code and generates a spatial positioning tag based on the rod type parameters, axial displacement information, and circumferential angle information; the spatial positioning tag includes an axial functional area, an axial sampling window, and a circumferential sector.

[0008] The safety monitoring center will form structural defect objects from structural inspection results that meet the structural defect conditions; it will also merge insulation anomaly inspection results that meet the insulation anomaly conditions and have the same spatial location tag as the structural defect object, or have the same axial functional area or circumferential sector and adjacent axial sampling windows, with the structural defect object to form fused defect objects; and it will form insulation anomaly verification objects from insulation anomaly inspection results that meet the insulation anomaly conditions but do not form fused defect objects. Adjacent axial sampling windows refer to two axial sampling windows having consecutive window numbers.

[0009] Insulation anomaly detection results include electrical response anomaly results and partial discharge anomaly results. Electrical response anomaly results include one or more of the following: partial leakage current anomaly results and equivalent insulation response anomaly results; partial discharge anomaly results include one or more of the following: partial discharge pulse anomaly results, ultra-high frequency coupling anomaly results, and ultrasonic coupling anomaly results. Defect objects include insulation rod identification codes, spatial positioning tags, anomaly source identifiers, review status identifiers, and defect level identifiers updated according to the defect level determination results; structural defect objects and fused defect objects also include defect morphology parameters, and insulation anomaly review objects and fused defect objects also include insulation anomaly parameters.

[0010] The pole type parameters include multiple parameters such as the end-operating head connection reference, the metal sleeve or adhesive bonding transition range, the pole body insulation working range, the inter-section connection position, the handguard limiting position, the handhold area range, and the tail-end sealing position. Axial functional zones include the end-operating head connection area, the metal sleeve or adhesive bonding transition area, the pole body insulation working area, the inter-section connection area, the handguard limiting adjacent area, the handhold area, and the tail-end sealing area; among these, the end-operating head connection area, the metal sleeve or adhesive bonding transition area, the inter-section connection area, and the handguard limiting adjacent area are designated as pre-set high-risk functional zones, while the remaining axial functional zones are non-high-risk functional zones.

[0011] The safety monitoring center controls the detection units to perform local and neighboring area verifications for insulation anomaly verification objects based on their spatial positioning tags, and writes the results of local and neighboring area verifications into the verification status identifier of the insulation anomaly verification object. Local verification means that the detection unit returns to the same axial sampling window and the same circumferential sector for verification; neighboring area verification means that the detection unit returns to adjacent axial sampling windows and the same circumferential sector within the same axial functional area for verification. When the defect level identifier of a structural defect object or a fused defect object is updated to a moderate or severe defect, the safety monitoring center controls the detection units to perform structural verification, insulation anomaly verification, or combined verification based on the corresponding spatial positioning tag, and writes the verification results into the verification status identifier of the corresponding defect object.

[0012] The safety monitoring center updates the defect level identifier and outputs status control instructions based on the anomaly source identifier of the structural defect object, fusion defect object, or insulation anomaly verification object, whether the axial functional area in the spatial positioning tag belongs to the preset high-risk functional area, and the verification status identifier. The status control instructions include verification positioning parameters and execution status fields; the verification positioning parameters include the insulation rod identification code, axial functional area, axial sampling window, and circumferential sector; the execution status fields include one of the following: pending verification at the detection station, restricted access, temporary shutdown lock, shutdown lock, release pending verification, release of restricted access, and release of temporary shutdown lock. The tool status execution unit executes the corresponding status control according to the status control instructions.

[0013] The detection unit includes a positioning and support assembly, a clamping and rotating assembly, an axial movement assembly, and a detection assembly. The positioning and support assembly supports the insulating rod and limits radial runout during the detection process; the clamping and rotating assembly drives the insulating rod to rotate around its own axis and outputs circumferential angle information; the axial movement assembly drives the detection assembly to move along the axial direction of the insulating rod and outputs axial displacement information. The detection assembly includes a structural detection assembly and an insulation anomaly detection assembly; the structural detection assembly includes one or more of an image acquisition assembly and a surface contour acquisition assembly, and the insulation anomaly detection assembly includes one or more of a local excitation electrode, a reference acquisition electrode, an end or handheld reference electrode, a partial discharge coupling sensor, an ultra-high frequency coupling sensor, and an ultrasonic coupling sensor.

[0014] The technical effects and advantages of the intelligent early warning system for insulating rods based on defect levels of the present invention are as follows: This invention uses spatial positioning tags as a common index for structural inspection results, insulation anomaly inspection results, verification results, and status control commands. This ensures that inspection and verification results from different sources are no longer recorded in isolation, but are continuously updated around defect objects with corresponding spatial positioning tags. The safety monitoring center uses the spatial positioning tags to categorize the inspection results into structural defect objects, fused defect objects, or insulation anomaly verification objects. It then updates the defect level identifier based on the anomaly source identifier, whether the axial functional area in the spatial positioning tag belongs to a preset high-risk functional area, and the verification status identifier. Thus, the fusion judgment of structural defects and insulation anomalies, the co-location verification and neighboring verification of unfused insulation anomalies, defect level updates, and retrieval status control form a closed loop. This reduces defect attribution errors and verification location offsets, providing a unified object basis for inspection station checks, restricted retrieval, temporary shutdown locking, shutdown locking, or release control, improving the consistency of insulation rod return inspection, verification, and retrieval management. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the defect object review and status control process based on spatial positioning tags according to the present invention. Detailed Implementation

[0016] 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.

[0017] The defect objects referred to in this invention include structural defect objects, fusion defect objects, and insulation anomaly verification objects. Each of these—structural defect objects, fusion defect objects, and insulation anomaly verification objects—is associated with an insulating rod identification code and a corresponding spatial positioning tag.

[0018] Example 1 This embodiment provides an intelligent early warning system for insulating rods based on defect levels, applied to the return inspection, verification, and retrieval status control of insulating rods at automatic inspection stations or in intelligent tool warehouses. The system includes a detection unit, a safety monitoring center, and a tool status execution unit.

[0019] The detection unit outputs structural detection results, insulation anomaly detection results, and corresponding axial displacement and circumferential angle information. The safety monitoring center retrieves the corresponding rod type parameters based on the insulation rod's identification code and generates a spatial positioning tag based on the rod type parameters, axial displacement information, and circumferential angle information. The spatial positioning tag includes an axial functional area, an axial sampling window, and a circumferential sector. Using the spatial positioning tag as an object index, the safety monitoring center forms structural defect objects from structural detection results that meet the structural defect conditions; merges insulation anomaly detection results that meet the insulation anomaly conditions and satisfy the fusion condition with the structural defect object with the structural defect object to form a fused defect object; and forms insulation anomaly verification objects from insulation anomaly detection results that meet the insulation anomaly conditions but do not form a fused defect object. The tool status execution unit executes corresponding status control according to status control commands.

[0020] The aforementioned spatial positioning tags are used to unify and associate structural inspection results, insulation anomaly inspection results, verification results, and subsequent status control information. This ensures that structural defect objects, fused defect objects, and insulation anomaly verification objects are all mapped to specific inspection locations, and serve as the index basis for defect fusion judgment, verification location, and status control command generation. Therefore, structural inspection results, insulation anomaly inspection results, verification results, and access status control can be updated around the same defect object with the corresponding spatial positioning tag, avoiding a disconnect between inspection records, verification locations, and on-site handling status.

[0021] The detection object in this embodiment is an insulated operating rod. The identification code of the insulated rod is JG-10-035-0217, with a total length of 1580mm and an outer diameter of 32mm. After reading the identification code of the insulated rod, the safety monitoring center retrieves the corresponding rod type parameters. The rod type parameters include the end working head connection reference, the metal sleeve or adhesive bonding transition range, the rod body insulation working range, the inter-section connection position, the hand guard limiting position, the handheld area range, and the tail end sealing position. In this embodiment, the end working head connection reference is the zero point at the front end of the rod body; the end working head connection area is 0mm to 30mm; the metal sleeve or adhesive bonding transition area is 30mm to 80mm; the rod body insulation working area is 80mm to 1120mm; the inter-section connection area is 1120mm to 1170mm; the hand guard limiting adjacent area is 1170mm to 1240mm; the handheld area is 1240mm to 1490mm; and the tail end sealing area is 1490mm to 1580mm. The end-operated head connection area, metal sleeve or adhesive bonding transition area, inter-section connection area, and handguard limiting area are designated as pre-set high-risk functional areas, while the pole insulation working area, handheld area, and tail-end sealing area are designated as non-high-risk functional areas. The pre-set high-risk functional areas are only one of the factors for determining the defect level update, and together with the anomaly source identification and review status identification, they determine the defect level identification.

[0022] In this embodiment, the end-working head connection area, metal sleeve or adhesive bonding transition area, inter-section connection area, and handguard limiting adjacent area are designated as preset high-risk functional areas. This designation is based on the technical attributes of these areas corresponding to the connection, transition, segmented assembly, force transmission, or operation limiting positions. Structural defects or insulation abnormalities in these areas are more likely to affect the reliability of the working end connection of the insulating rod, the continuity of the rod body, and the safety of handheld boundary identification or retrieval. Therefore, when updating the defect level label, the safety monitoring center uses whether the axial functional area in the spatial positioning label belongs to the preset high-risk functional area as a criterion.

[0023] The detection unit includes a positioning and support assembly, a clamping and rotating assembly, an axial movement assembly, and a detection assembly. The positioning and support assembly supports the insulating rod and limits radial runout during detection; the clamping and rotating assembly drives the insulating rod to rotate around its own axis and outputs circumferential angle information; the axial movement assembly moves the detection assembly along the axial direction of the insulating rod and outputs axial displacement information. The detection assembly includes a structural detection assembly and an insulation anomaly detection assembly. The structural detection assembly includes an image acquisition assembly and a surface contour acquisition assembly; the insulation anomaly detection assembly includes a local excitation electrode, a reference acquisition electrode, an end or handheld reference electrode, a partial discharge coupling sensor, an ultra-high frequency coupling sensor, and an ultrasonic coupling sensor. The axial displacement and circumferential angle information output by the detection unit are used not only to mark the detection position but also to control the axial movement assembly and the clamping and rotating assembly in the safety monitoring center, allowing the detection assembly to return to the corresponding axial sampling window and circumferential sector for verification.

[0024] In this embodiment, the axial sampling step size is 5mm, and the axial sampling windows are sequentially numbered W001, W002, W003, etc., starting from the zero point at the front end of the insulating rod. The clamping and rotating assembly rotates in 45° increments, forming eight circumferential sectors, denoted as S1 to S8. The reference sector corresponding to the initial zero-position calibration of the clamping and rotating assembly is taken as sector S1, and the remaining circumferential sectors are determined sequentially according to the graduation angle. The safety monitoring center determines the axial functional area based on the rod type parameters, the axial sampling window based on the axial displacement information, and the circumferential sector based on the circumferential angle information. A spatial positioning tag is generated from the axial functional area, the axial sampling window, and the circumferential sector. For example, the metal sleeve or adhesive transition area, W011, and S3 constitute a spatial positioning tag. This spatial positioning tag also serves as an index for the verification positioning parameters in the detection result attribution, fusion condition judgment, co-location verification, neighborhood verification, and status control commands.

[0025] Structural defect conditions include at least one of the following: crack length not less than 1.2 mm and maximum width not less than 0.08 mm; scratch length not less than 3.0 mm and maximum depth not less than 0.05 mm; notch depth not less than 0.20 mm; misalignment of connection not less than 0.30 mm; continuous arc length of contamination zone not less than 15 mm and axial length not less than 8 mm. Preset severe structural defect conditions include at least one of the following: crack length not less than 4.0 mm and maximum width not less than 0.15 mm; notch depth not less than 0.50 mm; misalignment of connection not less than 0.80 mm; continuous arc length of contamination zone not less than 40 mm and axial length not less than 20 mm; the proportion of defect morphology parameters exceeding the structural defect condition threshold relative to the same spatial positioning tag is not less than 100%.

[0026] When a crack, scratch, notch, or contamination zone spans more than two axial sampling windows, the safety monitoring center determines the main spatial positioning label based on the axial sampling window with the largest coverage ratio of the defect morphology parameters. If necessary, an association record is formed for adjacent axial sampling windows, and this association record is used as the basis for neighborhood fusion or neighborhood verification. Thus, even if the axial length of the contamination zone is greater than the single axial sampling step, the defect object will not be unclear in its attribution.

[0027] In this embodiment, the insulation anomaly detection result refers to the collective term for electrical response anomaly results and partial discharge anomaly results. An insulation anomaly detection result under the corresponding spatial positioning tag is considered to meet the insulation anomaly condition if any of the following conditions are met: the partial leakage current increases by more than 25% compared to the reference value for the same pole type; the equivalent insulation response decreases by more than 20% compared to the reference value for the same pole type; the partial discharge pulse count is not less than 12 times within a 10-second detection window; and both the ultra-high frequency coupling signal and the ultrasonic coupling signal exceed the corresponding calibration threshold. The aforementioned reference value for the same pole type and the corresponding calibration threshold are jointly determined by the reference data collected from qualified sample poles of the same pole type under the same testing environment, the retest data from decommissioned defective poles, and the preset safety margin, and are updated with each testing batch or preset cycle. Therefore, the anomaly judgment of partial leakage current, equivalent insulation response, partial discharge pulse count, ultra-high frequency coupling signal, and ultrasonic coupling signal has a reproducible reference source.

[0028] After receiving the detection results, the safety monitoring center forms a structural defect object from the structural detection results that meet the structural defect conditions. The structural defect object includes an insulating rod identification code, a spatial positioning tag, an anomaly source identifier, a review status identifier, a defect level identifier, and defect morphology parameters. The fused defect object also includes the defect morphology parameters of the corresponding structural defect object and the insulation anomaly parameters of the corresponding insulation anomaly detection result; the insulation anomaly review object also includes the insulation anomaly parameters of the corresponding insulation anomaly detection result. The review status identifier is used to record the review execution status and review result status of the defect object, and its values ​​include one or more of the following: not reviewed, same-site review anomaly, neighboring-site review anomaly, review not reproduced, structural review anomaly, severe structural review, and continuous same-site review partial discharge anomaly.

[0029] For insulation anomaly detection results that meet the insulation anomaly conditions, the safety monitoring center first determines whether the insulation anomaly detection result meets the fusion conditions with the already formed structural defect object. Fusion conditions include: the insulation anomaly detection result and the structural defect object have the same spatial location label; or, the insulation anomaly detection result and the structural defect object have the same axial functional area and circumferential sector, and their axial sampling windows are adjacent. Adjacent axial sampling windows mean that the window numbers of the two axial sampling windows are consecutive. When the fusion conditions are met, the safety monitoring center merges the corresponding insulation anomaly detection result with the structural defect object to form a fused defect object; when the insulation anomaly conditions are met but a fused defect object is not formed, the safety monitoring center forms an insulation anomaly verification object based on the corresponding insulation anomaly detection result.

[0030] In this embodiment, the same spatial positioning tag is used as the priority fusion condition because structural inspection data and insulation anomaly inspection data correspond to the same axial functional area, the same axial sampling window, and the same circumferential sector, indicating a spatial correspondence between them. The same axial functional area, the same circumferential sector, and adjacent axial sampling windows are used as the neighborhood fusion condition because crack ends, scratch edges, contamination zone extension areas, or locally damp areas may cross adjacent axial sampling windows, and the acquisition areas of local leakage current, equivalent insulation response, or partial discharge coupling signals may also cover the boundaries of adjacent windows. Insulation anomaly inspection results that do not meet the co-location or neighborhood fusion conditions are not directly merged into the structural defect object. Instead, they form insulation anomaly verification objects, and the safety monitoring center controls the detection unit to perform co-location verification and neighborhood verification according to their spatial positioning tags to distinguish between non-reproduced anomalies, positional offset anomalies, and adjacent expansion anomalies.

[0031] When the same insulation anomaly detection result meets the fusion conditions with multiple structural defect objects, the safety monitoring center prioritizes merging it with structural defect objects that have the same spatial positioning tag; if no structural defect object with the same spatial positioning tag exists, it is merged with the structural defect object whose axial sampling window is closest; the axial sampling window distance is the absolute value of the difference between the window numbers of the two axial sampling windows; if the axial sampling window distances are the same, and the structural defect object already has a defect level identifier, it is merged with the structural defect object with the higher defect level identifier; if neither has a defect level identifier, it is merged with the structural defect object whose defect morphology parameters correspond to a larger proportion of exceeding the limit for the structural defect conditions.

[0032] like Figure 1 As shown, after obtaining a structural defect object, a fusion defect object, or an insulation anomaly verification object, the safety monitoring center reads the corresponding insulation rod identification code and spatial positioning tag, and determines the verification path according to the defect object type. For structural defect objects, the safety monitoring center controls the detection unit to perform necessary verification according to the spatial positioning tag; for fusion defect objects, the safety monitoring center controls the detection unit to perform combined verification according to the spatial positioning tag; for insulation anomaly verification objects, the safety monitoring center controls the detection unit to perform co-location verification and neighborhood verification according to the spatial positioning tag. In this embodiment, combined verification includes structural verification of the structural detection results under the corresponding spatial positioning tag, and insulation anomaly verification of the insulation anomaly detection results within the same spatial positioning tag or adjacent axial sampling windows; the combined verification result is written into the verification status identifier of the corresponding fusion defect object. After the review is completed, the safety monitoring center writes the review result into the review status identifier, and generates a status control instruction based on whether the axial functional area in the anomaly source identifier and spatial positioning label belongs to the preset high-risk functional area and the review status identifier updates the defect level identifier. The tool status execution unit executes the detection station holding, review buffer, isolation buffer, retrieval lock or status writing according to the status control instruction.

[0033] Specifically, "co-location verification" refers to the safety monitoring center controlling the axial movement and clamping rotation components to return the detection component to the same axial sampling window and the same circumferential sector for verification. "Neighborhood verification" refers to the safety monitoring center controlling the axial movement and clamping rotation components to return the detection component to adjacent axial sampling windows and the same circumferential sector within the same axial functional area for verification. If adjacent axial sampling windows are located outside the boundary of the corresponding axial functional area, neighborhood verification only selects adjacent axial sampling windows existing within the same axial functional area. Co-location verification is used to determine whether the initial insulation anomaly can be reproduced within the same axial sampling window and the same circumferential sector; neighborhood verification is used to determine whether the insulation anomaly involves adjacent window expansion, detection boundary offset, or local anomaly area distribution across windows.

[0034] If both the same-site review and the neighboring review do not meet the insulation abnormality conditions, the safety monitoring center will update the review status identifier of the corresponding insulation abnormality review object to "review not reproduced" and may output a status control command to release the pending review; if the same-site review or the neighboring review meets the insulation abnormality conditions, the safety monitoring center will write the corresponding review result into the review status identifier and update the defect level identifier in combination with the axial functional area where the defect object is located and the abnormality source identifier.

[0035] The status control instructions include verification positioning parameters and execution status fields. Verification positioning parameters include the insulating rod identification code, axial functional area, axial sampling window, and circumferential sector. Execution status fields include one of the following: inspection station pending verification, restricted access, temporary disuse lock, disuse lock, release pending verification, release restricted access, and release temporary disuse lock. The tool status execution unit includes an inspection station holding mechanism, a verification buffer, an isolation buffer, a retrieval lock mechanism, and a rod status writer. The inspection station holding mechanism maintains the insulating rod in the inspection clamping state or temporarily prevents release when the inspection station pending verification is triggered; the verification buffer temporarily stores insulating rods requiring further verification or restricted access; the isolation buffer temporarily stores insulating rods with serious defects or suspected serious defects; the retrieval lock mechanism switches the corresponding storage location to a prohibited access state; and the rod status writer writes the execution status fields to the insulating rod electronic tag or tool management record.

[0036] Scenario 1: Formation of a Fusion Defect Object and Update of a Severe Defect. After the insulating operating rod numbered JG-10-035-0217 enters the detection unit, the unit collects structural detection results in the W011 axial sampling window and S3 circumferential sector of the metal sleeve or adhesive transition zone. The crack length is 2.8 mm and the maximum width is 0.11 mm. This structural detection result meets the structural defect conditions. The safety monitoring center forms a structural defect object, whose spatial positioning labels are metal sleeve or adhesive transition zone, W011, and S3. Under the same spatial positioning label, the detection unit collects a local leakage current that is 27% higher than the baseline value for the same rod type, and the partial discharge pulse count within a 10-second detection window is 16. This insulation anomaly detection result meets the insulation anomaly conditions and has the same spatial positioning label as the structural defect object. The safety monitoring center merges this insulation anomaly detection result with the structural defect object to form a fusion defect object. The axial functional area corresponding to this fusion defect object belongs to the preset high-risk functional area and includes partial discharge anomaly results, indicating that structural morphology defects and insulation anomalies occur simultaneously within the same defect area. The safety monitoring center updates the defect level identifier to critical defect and outputs a status control command with the execution status field set to temporary shutdown / lockdown. If, after review, the crack and partial discharge anomaly still meet the critical defect update conditions, the safety monitoring center updates the review status identifier to critical structural review and outputs a status control command with the execution status field set to shutdown / lockdown.

[0037] Scenario 2: Moderate Defect Update. In the metal sleeve or adhesive bonding transition areas W014 and S2, the detection unit collected structural inspection results with a crack length of 1.6 mm and a maximum width of 0.09 mm. This structural inspection result meets the structural defect conditions but does not meet the preset severe structural defect conditions. Furthermore, no insulation anomaly detection results meeting the insulation anomaly conditions were collected within the same spatial positioning label and adjacent axial sampling windows. The safety monitoring center identifies the structural defect object and, because its axial functional area belongs to the preset high-risk functional area, updates the defect level label to moderate defect, outputting the execution status field as a status control instruction pending verification at the inspection station. In the inter-joint connection areas W225 and S6, the detection unit collected structural inspection results with a scratch length of 3.4 mm and a maximum depth of 0.06 mm. An electrical response anomaly result with a 26% increase in local leakage current was collected within the same spatial positioning label. No partial discharge anomaly result meeting the partial discharge anomaly conditions was collected. The safety monitoring center forms a fusion defect object. Because the axial functional area corresponding to this fusion defect object belongs to the preset high-risk functional area, and includes abnormal electrical response results but not abnormal partial discharge results, the defect level is updated to a moderate defect if the conditions for updating severe defects are not met. In the pole insulation working areas W146 and S5, the detection unit collects structural inspection results with a scratch length of 3.2mm and a maximum depth of 0.05mm. In the adjacent axial sampling windows W147 and S5, an abnormal electrical response result with an equivalent insulation response decrease of 21% is collected. The safety monitoring center forms a fusion defect object based on the fusion conditions of the same axial functional area, the same circumferential sector, and adjacent axial sampling windows, and updates the defect level to a moderate defect. The output execution status field is a restricted access status control command.

[0038] Scenario 3: Review and Level Update of Insulation Anomaly Verification Objects. For the insulating operating rod numbered JG-10-035-0248, no structural inspection results meeting the structural defect conditions were collected in the inter-joint connection areas W226 and S6. However, insulation anomaly detection results were collected, indicating a local leakage current 29% higher than the baseline value for the same rod type. The safety monitoring center searched for structural defect objects within the same spatial positioning tag, the same axial functional area, the same circumferential sector, and adjacent axial sampling windows. No structural defect objects meeting the fusion conditions were found, thus forming an insulation anomaly verification object. This insulation anomaly verification object does not mean that insulation anomalies and structural defects will never have a corresponding relationship, but rather that, under the current inspection batch and current fusion conditions, no structural defect object that can form a co-location or neighboring fusion relationship with it has been found.

[0039] During the same-location verification, the safety monitoring center controls the axial movement component and the clamping rotation component to return the detection component to the inter-joint connection area W226, S6. The verification result does not meet the insulation anomaly condition. During the neighboring area verification, the safety monitoring center controls the axial movement component and the clamping rotation component to return the detection component to W225, S6 and W227, S6 within the same axial functional area. Among them, W227, S6 meets the electrical response anomaly condition. Since the axial functional area corresponding to the insulation anomaly verification object belongs to the preset high-risk functional area, the same-location verification result does not meet the insulation anomaly condition, while the neighboring area verification result does meet the insulation anomaly condition. The safety monitoring center updates the verification status identifier to "neighboring area verification anomaly." If the serious defect update condition is not met, the defect level identifier is updated to "medium defect," and the execution status field is set to "detection station pending verification."

[0040] For insulation anomaly verification objects located in pole insulation working areas W145 and S5 that still meet the electrical response anomaly conditions after in-situ verification, the safety monitoring center will update the verification status identifier to in-situ verification anomaly, update the defect level identifier to moderate defect, and output a status control command with restricted access in the execution status field. For insulation anomaly verification objects located in pole insulation working areas W171 and S4 that initially meet the partial discharge anomaly conditions, if two consecutive in-situ verifications meet the partial discharge anomaly conditions, the safety monitoring center will update the verification status identifier to continuous in-situ verification partial discharge anomaly, update the defect level identifier to severe defect, and output a status control command with temporary shutdown lockout in the execution status field; if two consecutive in-situ verifications do not meet the partial discharge anomaly conditions, the status will be updated to moderate defect if the severe defect update condition is not met.

[0041] Scenario 4: Severe Structural Defect and Verification Cancellation. Insulating operating rod number JG-10-035-0416 has a 0.56mm notch depth detected in the handguard limit area near W235 and S4, meeting the preset severe structural defect condition. The safety monitoring center creates a structural defect object, updates the defect level to severe defect, and outputs a status control command with a temporary shutdown lockout. If the structural verification result still meets the preset severe structural defect condition, the safety monitoring center updates the verification status to severe structural verification and outputs a status control command with a shutdown lockout. Insulating operating rod number JG-10-035-0402 did not have a structural defect condition detected in the rod body insulation working area W178 and S2, but it did have an insulation anomaly detection result showing a 26% increase in local leakage current. This insulation anomaly detection result did not form a fusion defect object; the safety monitoring center creates an insulation anomaly verification object and outputs a status control command for the detection station to be verified. Subsequently, both the local verification and the neighboring verification within the same axial functional area failed to meet the insulation anomaly condition. The safety monitoring center updated the verification status identifier to "verification not reproduced" and output an execution status field indicating the release of the pending verification status control command. This release process demonstrates that the status control in this embodiment does not rely solely on a single anomaly detection result to make an irreversible lockout. Instead, it uses the verification status as the basis for updating the defect level and execution status field, ensuring that the restriction access, temporary disabling lockout, disabling lockout, and release control are executed in a closed loop around the same defect object.

[0042] Comparative Example 1 In this comparative example, the detection device collects structural inspection results and insulation anomaly detection results, but does not generate spatial positioning tags including axial functional areas, axial sampling windows, and circumferential sectors. It only records the inspection results according to the entire insulating rod or a rough axial section. When the detection device detects cracks and local leakage current anomalies near the metal sleeve or adhesive transition area, it can only generate an anomaly record for the entire rod or a rough section. During verification, it cannot return to the original detection position according to the same axial sampling window and the same circumferential sector, nor can it determine whether the insulation anomaly detection results and the structural defect object meet the fusion conditions based on whether the axial sampling windows are adjacent. Compared with this embodiment, this comparative example lacks spatial positioning tags jointly defined by axial functional areas, axial sampling windows, and circumferential sectors, resulting in a lack of a unified index between structural defects, insulation anomalies, verification positions, and status control commands.

[0043] Comparative Example 2 In this comparative example, the detection device can generate spatial positioning tags and form structural defect objects and fused defect objects, but it does not form insulation anomaly verification objects for insulation anomaly detection results that meet the insulation anomaly conditions but do not form fused defect objects. When the detection device collects equivalent insulation response anomalies in the pole insulation working areas W145 and S5, and there are no structural defect objects that meet the structural defect conditions in the same spatial positioning tag and adjacent axial sampling windows, the insulation anomaly detection result is only recorded as ordinary anomaly data. It cannot perform co-location verification and neighborhood verification according to the spatial positioning tag, nor can it write the verification result into the verification status identifier and enter the status control command output process. Compared with this embodiment, this comparative example cannot form continuously updated defect objects for non-fused insulation anomaly detection results, which easily leads to a disconnect between the verification, classification, and access status control of isolated insulation anomalies.

Claims

1. An intelligent early warning system for insulating rods based on defect levels, characterized in that, The system includes a detection unit, a safety monitoring center, and a tool status execution unit. The detection unit outputs structural detection results, insulation anomaly detection results, and corresponding axial displacement and circumferential angle information. The safety monitoring center calls up the rod type parameters based on the insulation rod's identification code and generates a spatial positioning label including an axial functional area, an axial sampling window, and a circumferential sector based on the rod type parameters, axial displacement information, and circumferential angle information. Structural detection results that meet the structural defect conditions form a structural defect object. When an insulation anomaly detection result that meets the insulation anomaly conditions has the same spatial positioning label as the structural defect object, or when the axial functional area and circumferential sector are the same and the axial sampling window is adjacent, it is merged with the structural defect object to form a fused defect object. When an insulation anomaly condition is met but a fused defect object is not formed, an insulation anomaly verification object is formed. For the insulation anomaly verification object, the safety monitoring center controls the detection unit to perform co-location verification and neighborhood verification according to its spatial positioning label. It also updates the defect level label based on the anomaly source identifier of the structural defect object, fused defect object, or insulation anomaly verification object, whether the axial functional area in the spatial positioning label belongs to a preset high-risk functional area, and the verification status label, and outputs status control instructions. The tool status execution unit executes the corresponding status control according to the status control command.
