Description

Technical Field

[0001] This invention relates to the field of power distribution equipment protection and monitoring technology, specifically to an integrated device, method, equipment, and medium for visual protection and monitoring of distribution boxes, cable branch boxes, and metering boxes. Background Technology

[0002] Distribution boxes, cable branch boxes, and metering boxes are core terminal equipment in power distribution systems, undertaking important functions of power distribution and equipment protection. The stability of their operation directly affects the safety of the entire power distribution system. In actual operation and maintenance, maintenance personnel need to regularly inspect the operating status of internal components and wiring conditions, and promptly identify potential hazards such as loosening, aging, and overheating. However, there is a clear contradiction between the protection and visual monitoring of traditional power distribution equipment.

[0003] Currently, most existing distribution boxes, cable branch boxes, and metering boxes adopt a fully enclosed metal enclosure structure with only a small maintenance window on the door panel. During inspections, the cabinet door must be opened to observe the internal condition, which is not only cumbersome but also poses safety hazards such as accidental contact and electric shock during the opening process. This is especially true in high-voltage live-line inspection scenarios, where safety is extremely low. Although some switchgear has transparent observation windows, they are mostly made of ordinary glass, lacking scratch-resistant, anti-fog, and flame-retardant properties. After long-term use, the glass is prone to blurring and damage, making it impossible to clearly observe the internal condition. Furthermore, they lack auxiliary monitoring functions, making it difficult to detect hidden hazards.

[0004] In addition, traditional transparent protective structures are mostly fixed designs, which cannot flexibly adjust the observation angle according to the layout of internal components. It is difficult to observe components such as busbars and terminals deep inside the switch cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated visual protection and monitoring device, method, equipment, and medium for distribution boxes, cable branch boxes, and metering boxes. This device allows for safe and clear observation of the internal status without opening the cabinet door, avoiding the risk of electric shock; and it can flexibly adjust the observation angle to improve the safety and convenience of inspections.

[0006] To achieve the above objectives, embodiments of the present invention provide an integrated visual protection and monitoring device for distribution boxes, cable branch boxes, and metering boxes, comprising: A transparent protective component is installed on the enclosure of a distribution box, cable branch box, or metering box. The transparent protective component includes high-strength transparent flame-retardant glass, anti-scratch and anti-fog coatings on the inner and outer sides of the high-strength transparent flame-retardant glass, and a protective frame around the high-strength transparent flame-retardant glass. An auxiliary monitoring component is embedded within the protective frame of the transparent protective component for real-time monitoring of the internal status of the distribution box, cable branch box, or metering box. The sealing and fixing assembly includes a sealing strip at the connection between the transparent protective assembly and the housing, a clamping bolt for tightening and fixing, and a positioning buckle for positioning and installation. An angle adjustment component, connected to the transparent protective component and the housing, adopts a partitioned independent adjustment and multi-point self-locking linkage structure to adjust the observation angle of the transparent protective component.

[0007] Optionally, the anti-scratch and anti-fog coating includes an inner anti-fog coating and an outer anti-scratch coating; wherein, The inner anti-fog coating is a hydrophilic nano-silica / polymer composite coating, which is formed after coating and curing. The outer anti-scratch coating is an organic-inorganic hybrid wear-resistant coating, which is formed after coating, UV exposure or heat curing.

[0008] Optionally, for cable branch boxes or metering boxes, the transparent protection component adopts a partitioned design, including multiple independent transparent protective windows corresponding to the busbar compartment, cable compartment, and control room respectively, with the size of each protective window adapted to the corresponding area; For the distribution box, the transparent protective component adopts an integrated transparent protective cover, which has a flip-up design.

[0009] Optionally, the angle adjustment assembly includes a self-locking hinge and a damping element disposed between the protective frame and the housing; The self-locking hinge includes a first hinge arm, a second hinge arm, and a hinge shaft. The first hinge arm is fixed to the protective frame, the second hinge arm is fixed to the housing, and the hinge shaft passes between the first hinge arm and the second hinge arm. The first hinge arm and the second hinge arm are respectively provided with self-locking inclined surfaces on their contact surfaces. When the protective frame rotates to a preset angle range, the two self-locking inclined surfaces press against each other under the gravity of the protective frame and the first hinge arm to form a self-lock to maintain the current angle. The damping element is sleeved on the hinge shaft and clamped between the first hinge arm and the second hinge arm. It is used to provide constant rotational damping during the rotation of the protective frame, so that the protective frame can be stably suspended and positioned at any angle within the range of 0° to 90°.

[0010] Optionally, the auxiliary monitoring component includes: A miniature high-definition camera is embedded within the protective frame of a transparent protective component, with the lens facing inwards from the device; The supplementary lighting module, linked to the miniature high-definition camera, is used to provide supplementary lighting when there is insufficient light inside the device. The data transmission unit is electrically connected to the miniature high-definition camera and is used to push the captured images to the maintenance terminal in real time. The miniature high-definition camera has a built-in anomaly recognition algorithm. When it detects abnormal conditions such as component overheating, loose wiring, or condensation, it triggers an alarm signal and pushes it to the maintenance terminal through the data transmission unit.

[0011] Optional anomaly detection algorithms include: The loose wiring identification unit is used to extract the edge features of the wiring and terminal areas in the image based on edge detection and contour matching, and compare them with the preset standard contour and standard spacing. When the edge offset exceeds the set threshold, it is determined to be a wiring abnormality. The heat-generating area identification unit is used to extract the color distribution features and temperature rise area color blocks on the surface of components based on color space fusion and temperature pseudo-color mapping. When the temperature rise value or relative temperature value exceeds the preset temperature threshold, it is determined to be an abnormal heat generation. The condensation recognition unit is used to analyze the blurring, uniformity and diffuse reflection changes of the inner wall of the transparent flame-retardant glass and the surface of the components based on image texture features and gray-scale variance analysis. When the gray-scale variance value is lower than a preset threshold, it is determined to be an abnormal condensation.

[0012] Optionally, the sealing and fixing assembly adopts a multi-layer sealing and graded compression structure; The sealing strip is made of high-temperature and corrosion-resistant silicone rubber, with a double U-shaped composite cross-section structure. It has two continuous sealing lips on the inner side and anti-slip pressing texture on the outer side. The sealing strip is detachably embedded in the sealing groove of the protective frame. The clamping bolts are multiple and evenly distributed along the circumference of the protective frame, used to clamp and fix the protective frame to the box body; The positioning buckle is a flexible snap-fit ​​structure, including a male buckle and a female buckle; wherein, the male buckle is fixed to the bottom of the protective frame, and the female buckle is embedded in the inner wall of the box. The male buckle and the female buckle are inserted and matched to achieve quick positioning and installation. A buffer pad is sandwiched between the protective frame and the high-strength transparent flame-retardant glass; The auxiliary monitoring component has a ring-shaped waterproof sealing structure at the installation position of the miniature high-definition camera, including: an O-ring fitted around the camera and a waterproof isolation cavity surrounding the miniature high-definition camera; wherein, the O-ring is compressed between the camera and the protective frame, and the waterproof isolation cavity and the protective frame are integrally injection molded.

[0013] Secondly, the present invention also provides a visual protection and monitoring method for an integrated visual protection and monitoring device for distribution boxes, cable branch boxes, and metering boxes, comprising: The transparent protective component is fixed to the enclosure of the distribution box, cable branch box or metering box by the sealing and fixing component, and the observation angle of the transparent protective component is adjusted by the angle adjustment component so that it is aligned with the area to be observed inside the equipment. The auxiliary monitoring component is activated to control the miniature high-definition camera to collect images of the inside of the device in real time. The built-in anomaly recognition algorithm is used to analyze the collected images of the inside of the device to identify at least one of the following: abnormal heating, abnormal loose wiring, or abnormal condensation. The anomaly identification algorithm includes identifying loose wiring based on Canny edge detection and contour matching algorithm, identifying heating areas based on RGB-HSV color space fusion and temperature pseudo-color mapping algorithm, and identifying condensation based on image texture features and grayscale variance algorithm. When an anomaly is detected, an alarm signal is generated that includes the anomaly type, the time of occurrence, the coordinates of the location of the anomaly, and an image of the anomaly, and is pushed to the operation and maintenance terminal.

[0014] Thirdly, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the above-described visualization protection and monitoring method for an integrated visualization protection and monitoring device for distribution boxes, cable branch boxes, and metering boxes.

[0015] Fourthly, the present invention also provides a storage medium storing a computer program thereon, wherein the computer program, when executed by a processor, implements the steps of the above-described visualization protection and monitoring method for the integrated visualization protection and monitoring device for distribution boxes, cable branch boxes, and metering boxes.

[0016] The above technical solution, by incorporating an anti-scratch and anti-fog coating and transparent protective components, allows maintenance personnel to clearly and safely observe the internal status of the equipment without opening the cabinet door, avoiding the risk of accidental contact and electric shock during live inspections. Furthermore, the angle adjustment component allows for flexible adjustment of the observation angle of the transparent protective component, improving the safety and convenience of power distribution equipment inspections.

For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.

[0023] 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.

[0024] See Figure 1The diagram shown is a schematic representation of a visual protection and monitoring integrated device for distribution boxes, cable branch boxes, and metering boxes in a specific embodiment, including: A transparent protective component 1 is installed on the housing 10 of a distribution box, cable branch box or metering box. The transparent protective component includes high-strength transparent flame-retardant glass, anti-scratch and anti-fog coatings on the inner and outer sides of the high-strength transparent flame-retardant glass, and a protective frame 11 around the high-strength transparent flame-retardant glass. An auxiliary monitoring component is embedded within the protective frame 11 of the transparent protective component for real-time monitoring of the internal status of the distribution box, cable branch box, or metering box. The sealing and fixing assembly 2 includes a sealing strip at the connection between the transparent protective assembly and the housing 10, a clamping bolt for tightening and fixing, and a positioning buckle for positioning and installation. An angle adjustment component, connected to the transparent protective component and the housing 10, adopts a partitioned independent adjustment and multi-point self-locking linkage structure to adjust the observation angle of the transparent protective component.

[0025] Furthermore, the transparent glass of the transparent protective component 1 is provided with scale lines, which can help maintenance personnel observe the spacing between components and the length of wiring, making it easier to check for potential problems such as loose wiring and component misalignment; the scale lines are printed with high-temperature resistant and non-fading ink, which is clearly distinguishable and does not affect the observation effect.

[0026] Furthermore, the anti-scratch and anti-fog coating includes an inner anti-fog coating and an outer anti-scratch coating; wherein, the inner anti-fog coating is a hydrophilic nano-silica / polymer composite coating, which is formed after coating and curing; the outer anti-scratch coating is an organic-inorganic hybrid wear-resistant coating, which is formed after coating and UV or thermal curing.

[0027] In one specific embodiment, the anti-scratch and anti-fog coating is prepared independently on both the inner and outer sides: the inner side is a nano-hydrophilic anti-fog coating, the main materials of which are nano-silica sol, waterborne polyurethane dispersion, and polyether-modified polysiloxane leveling agent, with a ratio of nano-silica sol: waterborne polyurethane: leveling agent = 85:12:3; the outer side is a high-hardness wear-resistant and anti-scratch coating, the main materials of which are UV-curable acrylate, silicone-modified wear-resistant resin, and photoinitiator 1173, with a ratio of UV acrylate: silicone wear-resistant resin: photoinitiator = 75:22:3. Construction process parameters: The glass substrate is degreased with anhydrous ethanol, rinsed with deionized water, and dried at 80℃ for 10 min; the inner anti-fog coating is applied by spraying, with a spraying pressure of 0.3–0.5MPa, a film thickness of 8–12μm, and leveled at room temperature for 5 min, then cured at 120℃ for 30 min; the outer anti-scratch coating is applied by roller coating, with a wet film thickness of 15–20μm, and cured by UV curing with an energy of 800–1000mJ / cm², resulting in a pencil hardness ≥7H after curing.

[0028] The inner coating must ensure a light transmittance of ≥92% and a haze of ≤1% while maintaining high hydrophilicity and anti-fog properties to avoid conflict with optical observation performance. It must also withstand 10 hours of humid heat cycling within the enclosure without peeling or whitening. The outer coating must ensure adhesion of grade 0 and resistance to artificial aging of ≥3000 hours without significant wear while maintaining high hardness, thus solving the problem of coating failure caused by outdoor wind and sand abrasion and ultraviolet aging. In addition, cross-contamination between the inner and outer coatings must be avoided to ensure that the film layer is uniform, free of pinholes and drips, and that long-term use does not affect the clarity of camera imaging and visual observation.

[0029] In one specific implementation, see [reference] Figure 2 As shown, for cable branch boxes or metering boxes, the transparent protective assembly 1 adopts a partitioned design, including multiple independent transparent protective windows corresponding to the busbar compartment 12, cable compartment 13, and control compartment 14, respectively. The size of each protective window is adapted to the corresponding area. For example, the protective window size of busbar compartment 12 is 600mm long × 400mm wide, and the protective window size of cable compartment 13 is 500mm long × 300mm wide.

[0030] For the distribution box, the transparent protective component 1 adopts an integral transparent protective cover, which has a flip-up design. For example, the integral transparent protective cover is 400mm long and 300mm wide.

[0031] Specifically, the angle adjustment component includes a self-locking hinge and a damping element disposed between the protective frame and the housing; The self-locking hinge includes a first hinge arm, a second hinge arm, and a hinge shaft. The first hinge arm is fixed to the protective frame, the second hinge arm is fixed to the housing, and the hinge shaft passes between the first and second hinge arms. The first and second hinge arms are respectively provided with self-locking inclined surfaces on their contact surfaces. When the protective frame rotates to a preset angle range, the two self-locking inclined surfaces press against each other under the gravity of the protective frame and the first hinge arm to form a self-lock and maintain the current angle. The damping element is sleeved on the hinge shaft and clamped between the first hinge arm and the second hinge arm. It is used to provide constant rotational damping during the rotation of the protective frame, so that the protective frame can be stably suspended and positioned at any angle within the range of 0° to 90°.

[0032] In one specific embodiment, the angle adjustment component further includes an angle sensor, which is a magnetoelectric non-contact angle sensor, including a permanent magnet fixed at the pivot of the protective frame and a magnetic induction element fixed on the housing; the magnetic induction element is used to detect the change in the direction of the magnetic field generated by the rotation of the permanent magnet and output two orthogonal signals with a phase difference of 90°, and the current rotation angle of the protective frame is obtained by arctangent calculation.

[0033] Specifically, the current rotation angle is calculated using the following formula:

[0034] In the formula, This is the absolute rotation angle of the axis of rotation. , These are the voltage signals output by the two magnetic induction elements, respectively.

[0035] Furthermore, the auxiliary monitoring component includes: A miniature high-definition camera is embedded within the protective frame 11 of the transparent protective component 1, with the lens facing inwards from the device; The supplementary lighting module, linked to the miniature high-definition camera, is used to provide supplementary lighting when there is insufficient light inside the device. The data transmission unit is electrically connected to the miniature high-definition camera and is used to push the captured images to the maintenance terminal in real time. The miniature high-definition camera has a built-in anomaly recognition algorithm. When it detects abnormal conditions such as component overheating, loose wiring, or condensation, it triggers an alarm signal and pushes it to the maintenance terminal through the data transmission unit.

[0036] Specifically, anomaly detection algorithms include: The loose wiring identification unit is used to extract the edge features of the wiring and terminal areas in the image based on edge detection and contour matching, and compare them with the preset standard contour and standard spacing. When the edge offset exceeds the set threshold, it is determined to be a wiring abnormality. The heat-generating area identification unit is used to extract the color distribution features and temperature rise area color blocks on the surface of components based on color space fusion and temperature pseudo-color mapping. When the temperature rise value or relative temperature value exceeds the preset temperature threshold, it is determined to be an abnormal heat generation. The condensation recognition unit is used to analyze the blurring, uniformity and diffuse reflection changes of the inner wall of the transparent flame-retardant glass and the surface of the components based on image texture features and gray-scale variance analysis. When the gray-scale variance value is lower than a preset threshold, it is determined to be an abnormal condensation.

[0037] For example, the camera of the auxiliary monitoring component supports timed shooting and anomaly capture functions, and the timed shooting frequency can be set. At the same time, it has a built-in lightweight embedded anomaly recognition algorithm. The algorithm adopts a front-end edge computing architecture and runs independently on the embedded chip, so that it can achieve real-time detection and local early warning without relying on the cloud.

[0038] The specific implementation logic and parameters are as follows: Based on the Canny edge detection and contour matching algorithm, loose wiring and detached terminals are identified. Edge features of the wiring and terminal areas are extracted and compared with standard contours and standard spacing. A positional offset threshold ≥2mm is considered a wiring abnormality. Based on the RGB-HSV color space fusion and temperature pseudo-color mapping algorithm, heat-generating areas are identified. Color distribution features on the component surface and color blocks in temperature-rising areas are extracted. A temperature rise ≥5℃ or relative humidity ≥70℃ is considered a heating abnormality. Based on image texture features and grayscale variance algorithm, condensation is identified. By analyzing the blurriness, uniformity, and diffuse reflection changes of the glass inner wall and component surface, a grayscale variance value below a set threshold is considered a condensation abnormality. When abnormalities such as component overheating, loose wiring, or condensation are detected, an alarm signal is automatically triggered and pushed to the maintenance terminal via the data transmission unit, reminding maintenance personnel to handle the situation promptly.

[0039] Furthermore, the sealing and fixing assembly 2 adopts a multi-layer sealing and graded compression structure; The sealing strip is made of high-temperature and corrosion-resistant silicone rubber, and its cross-section is a double U-shaped composite cross-section structure. It has two continuous sealing lips on the inner side and anti-slip pressing texture on the outer side. The sealing strip is detachably embedded in the sealing groove of the protective frame 11. Multiple clamping bolts are evenly distributed around the circumference of the protective frame 11, and are used to clamp and fix the protective frame 11 to the housing 10. The positioning buckle is an elastic snap-fit ​​structure, including a male buckle and a female buckle; wherein, the male buckle is fixed to the bottom of the protective frame 11, and the female buckle is embedded in the inner wall of the housing 10. The male buckle and the female buckle are inserted and matched to achieve quick positioning and installation. A buffer pad is sandwiched between the protective frame 11 and the high-strength transparent flame-retardant glass; The auxiliary monitoring component has a ring-shaped waterproof sealing structure at the installation position of the miniature high-definition camera, including: an O-ring fitted around the camera and a waterproof isolation cavity surrounding the miniature high-definition camera; wherein, the O-ring is compressed between the camera and the protective frame 11, and the waterproof isolation cavity and the protective frame 11 are integrally injection molded.

[0040] Furthermore, the sealing strip has anti-slip textures on its surface to enhance its fit with the housing 10 and the transparent protective component 1, thereby improving its sealing performance. At the same time, the sealing strip is designed to be detachable, making it easy to replace later and reducing maintenance costs.

[0041] In this embodiment, by integrating high-strength transparent flame-retardant glass and scratch-resistant and anti-fog coatings on the inner and outer sides, the internal status of the equipment can be clearly and safely observed without opening the cabinet door, avoiding the risk of accidental contact and electric shock during live inspection; the partitioned transparent protective window is adaptable to different equipment structures, the integrated protective cover facilitates comprehensive observation of the distribution box, and the angle adjustment component solves the problem of difficulty in observing deep busbars, wiring terminals and other components in traditional fixed structures.

[0042] In one embodiment, Figure 3 This is a detailed flowchart of a visual protection monitoring method according to an embodiment of the present invention. This embodiment is further optimized and expanded based on the above embodiments.

[0043] S200: The transparent protective component is fixed to the enclosure of the distribution box, cable branch box or metering box by the sealing and fixing component, and the observation angle of the transparent protective component is adjusted by the angle adjustment component so that it is aligned with the area to be observed inside the equipment.

[0044] S201: Activate the auxiliary monitoring component to control the miniature high-definition camera to collect images of the equipment's interior in real time, and analyze the collected images of the equipment's interior through the built-in anomaly recognition algorithm to identify at least one of the following: abnormal heating, abnormal loose wiring, or abnormal condensation.

[0045] The anomaly identification algorithm includes identifying loose wiring based on Canny edge detection and contour matching algorithm, identifying heating areas based on RGB-HSV color space fusion and temperature pseudo-color mapping algorithm, and identifying condensation based on image texture features and grayscale variance algorithm.

[0046] For example, the color image captured by the miniature high-definition camera is first converted to grayscale, transforming the RGB three channels into a single-channel grayscale image to reduce data dimensionality. Then, Gaussian filtering is used to smooth and denoise the grayscale image, eliminating Gaussian noise that may have been introduced during acquisition while preserving edge information. The Canny edge detection operator is applied to calculate the gradient magnitude and direction of each pixel in the image. Edges are refined using non-maximum suppression, and then high and low thresholds are used for edge connection and false edge suppression, ultimately generating a binary edge map. Based on this, a contour extraction algorithm is used to traverse and filter the connected regions in the binary edge map to obtain the closed contours of terminals and connections, and the geometric moments, area, perimeter, and other feature parameters of each contour are calculated.

[0047] The extracted actual contour is then matched with a standard contour template pre-stored in the system. Simultaneously, the coordinates of key points on the actual contour are compared with the standard positions to obtain the edge offset. If the contour matching similarity is below a preset threshold or the edge offset exceeds 2mm, a loose or abnormal connection is detected at the terminal block or wiring, and a corresponding alarm is output.

[0048] Color images captured by a miniature high-definition camera are converted from the RGB color space to the HSV color space. The hue component is separated to characterize the color type of the component surface, and the saturation component reflects the purity and grayscale inclusion of the color. Simultaneously, the proportional relationship between the red, green, and blue components in the original RGB space is preserved, and the proportion of the red component is calculated to enhance sensitivity to the red-heat characteristics of high-temperature regions. Subsequently, a temperature pseudo-color mapping function is used to fuse the hue, saturation, and red component proportion into a pseudo-color temperature distribution image. Typically, low-temperature regions are represented by blue-green, medium-temperature regions by yellow-green, and high-temperature regions by red-white, and a color-temperature correspondence curve is established.

[0049] Based on this, threshold segmentation and connected component analysis are performed on the mapped pseudo-color image to extract red and white blocks representing high-temperature regions. The area, average pseudo-color temperature value, and temperature rise value relative to the normal environment region of each block are calculated. When the area of ​​the red and white blocks in a certain region exceeds the preset minimum area threshold, and the calculated temperature rise value exceeds 5℃ or the absolute relative temperature reaches 70℃ or above, it is determined that there is a heating anomaly in that region, and the location coordinates and anomaly level of the heating region are output.

[0050] Images captured by a miniature high-definition camera are divided into multiple local windows. The variance of the pixel grayscale values ​​within each window is calculated to characterize the texture uniformity of that area. A larger grayscale variance indicates richer texture details, while a smaller variance indicates a smoother and more uniform surface. When condensation forms tiny water droplets or films on the inner wall of high-strength transparent flame-retardant glass or the surface of components, it reduces the contrast and detail of the surface texture, leading to a significant drop in the local grayscale variance value. By comparing the grayscale variance of each window with a pre-calibrated variance threshold under normal dry conditions, condensation is suspected when a set proportion of windows have variances below the threshold.

[0051] S202: When an anomaly is detected, an alarm signal is generated that includes the anomaly type, the time of the anomaly, the coordinates of the anomaly location, and an image of the anomaly, and is pushed to the operation and maintenance terminal.
