Description

Technical Field

[0001] This invention belongs to the field of cable accessory assembly data acquisition technology, specifically relating to a cable data acquisition system and method for outdoor terminal manufacturing sites, which is particularly suitable for three-dimensional cable data acquisition operations in high-altitude tower environments. Background Technology

[0002] In power transmission and distribution networks, outdoor cable terminals, as critical nodes connecting cables and towers, directly determine the stability and security of power transmission through their manufacturing quality. Accurate data collection from the cables on the towers is a core prerequisite for ensuring terminal manufacturing quality and achieving efficient subsequent operation and maintenance during the outdoor terminal manufacturing process. Workers need to acquire key information such as point cloud data and 3D models of the cables. This data is not only the foundation for cable feature extraction, key parameter measurement, and hidden defect detection, but also crucial for achieving full lifecycle data backup of cable terminals, fault tracing, and optimization of operation and maintenance plans, directly impacting the stability and security of the power transmission network.

[0003] However, conducting 3D data acquisition at high-altitude cable terminal work sites still faces several pressing challenges. These problems severely restrict work efficiency and data quality, and even pose safety hazards:

[0004] First, the limited space for high-altitude operations poses a severe challenge to equipment operation. Outdoor pole-mounted work platforms or suspended scaffolds offer limited operating space, which is further constrained by the pole structure and surrounding cable routing. In traditional data acquisition processes, control equipment such as laptops must be carried to the heights with the construction personnel. This not only occupies already limited working space but also poses a high risk of falling due to the instability of the high-altitude environment. During operations, even slight platform swaying, accidental tool collisions, or operator negligence can cause laptops to fall from heights, resulting in equipment damage worth tens of thousands of yuan and potentially posing a fatal threat to ground workers, pedestrians, and surrounding facilities, severely conflicting with the power industry's "safety first" operating principle.

[0005] Secondly, manual handheld scanning has shortcomings in both accuracy and safety. Currently, mainstream cable 3D data acquisition still relies on workers holding scanning equipment. This method's deficiencies are further amplified in high-altitude environments: From an accuracy perspective, workers must hold the equipment while suspended in mid-air, significantly reducing arm stability due to platform sway and worker fatigue, making it difficult to guarantee the uniformity and completeness of the scanning trajectory. Furthermore, obstructions such as pole supports and intersecting cables easily create blind spots, resulting in distorted contours and blurred details in the final 3D model, often failing to meet the stringent requirements of final product manufacturing. From a safety perspective, to cover the entire circumference of the cable, workers must frequently move the equipment on narrow platforms, sometimes even leaning out to avoid obstructions, greatly increasing the risk of falls due to loss of balance. Simultaneously, prolonged holding of the scanning equipment leads to arm muscle fatigue, further reducing operational stability and creating a vicious cycle of insufficient accuracy – repeated adjustments – increased fatigue.

[0006] Furthermore, design flaws in traditional scanning equipment exacerbate the operational difficulties. On one hand, some wired scanning devices require connection to the control terminal via data cables. During the scanning process, workers must move in a 360° circle around the cable, making the data cables prone to tangling and knotting with the tower structure and the cable itself. This can lead to data transmission interruptions, requiring shutdowns to tidy up the cables and delaying the work progress; in severe cases, the cables may pull on the scanning equipment, causing damage and safety risks. On the other hand, the randomness and limitations of manual handheld scanning mean that a single scan cannot cover the entire cable area. Workers often need to scan repeatedly to complete the data, which not only significantly extends the work time but also reduces the overall accuracy of the 3D model due to data splicing errors from multiple scans, severely failing to meet the power industry's requirements for "efficient and precise" operations.

[0007] In summary, existing cable data acquisition methods are no longer suitable for the high-altitude working environment at outdoor terminal manufacturing sites. Their shortcomings in spatial adaptability, equipment safety, data accuracy, and operational efficiency have become key bottlenecks restricting the development of intelligent operation and maintenance in the power industry.

[0008] Therefore, developing a cable data acquisition system that can accurately handle high-altitude operation scenarios and solve problems such as limited space, equipment risks, insufficient accuracy, and low efficiency has become an important issue that urgently needs to be addressed in the power industry. Summary of the Invention

[0009] In view of the above-mentioned or existing technical deficiencies, the present invention proposes a cable data acquisition system and method for outdoor terminal manufacturing sites, which overcomes the defects of existing technologies in high-altitude cable data acquisition at outdoor terminal manufacturing sites, such as limited working space, high risk of equipment falling, and low data acquisition accuracy and efficiency.

[0031] As a further technical solution of the present invention, the wireless laser scanner has a scanning accuracy of not less than 0.05mm and a scanning speed of not less than 1000 points / second.

[0032] Secondly, this invention proposes a cable data acquisition method for outdoor terminal manufacturing sites, comprising:

[0033] The scanner mounted on the slide rail scans the cable to be scanned to obtain the raw data of the cable.

[0034] The scanner wirelessly transmits the raw data from the cable to the microprocessor;

[0035] The microprocessor constructs a 3D model of the cable based on the original cable data and sends it to the VR device;

[0036] VR devices receive real-time screen projection images transmitted by a microprocessor and enable remote control of the microprocessor.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. This solution achieves physical separation between the control terminal and the high-altitude work site by wirelessly connecting the VR device and the microprocessor. The microprocessor can be placed in a safe area on the ground, and construction personnel can remotely control the equipment using only a lightweight VR device. This design not only solves the problem of unstable placement of control equipment on narrow high-altitude platforms, but also eliminates the risk of laptops falling from heights due to collisions or shaking. This protects equipment assets and eliminates safety threats to personnel and facilities on the ground, complying with the safety regulations for high-altitude operations in the power industry.

[0039] 2. This invention relies on the automated drive of a circular slide rail and drive mechanism, allowing the wireless laser scanner to move autonomously along the circumference of the cable. This eliminates the need for construction personnel to frequently move the equipment on the high-altitude platform or lean out to avoid obstructions. Simultaneously, it relieves the physical burden of holding heavy equipment for extended periods, effectively alleviating work fatigue and reducing falls from heights caused by fatigue or loss of balance. This significantly improves operational safety and personnel comfort, and lowers the risks associated with personnel operations.

[0040] 3. The driving mechanism of this invention drives the wireless laser scanner to perform uniform and controllable closed-loop motion along the annular slide rail. The scanning path can accurately cover key parts such as the cable surface, joints, and insulation layers, completely solving the problems of blind spots and data loss caused by manual handheld scanning due to arm tremors and obstructed vision. It achieves accurate data acquisition in all dimensions.

[0041] 4. The automated closed-loop scanning mode of this invention can acquire complete data of the entire circumference of the cable in a single scan, eliminating the need for repeated manual adjustments and rescanning, thus shortening the single acquisition time and improving work efficiency. Simultaneously, the real-time monitoring and remote control functions of the VR glasses, combined with the integrated "acquisition-processing-modeling" workflow of the laptop, significantly shorten the data delivery cycle and optimize the work process.

[0042] 5. The wireless laser scanner, VR glasses, and laptop of this invention all use wireless communication technology to transmit data and instructions, abandoning the traditional wired connection method. This fundamentally avoids data interruption and equipment damage caused by cables getting tangled and knotted with poles and towers during the scanning process, making it suitable for working environments with multiple cables and complex pole structures at high altitudes.

[0043] 6. The VR glasses of this invention adopt a visual interface and controller operation logic, reducing the professional skill requirements for construction personnel. A single person can complete the entire process, reducing the need for high-altitude work personnel. At the same time, the high-precision 3D model and point cloud data can be directly used for digital archiving of cable terminals, fault tracing, and optimization of operation and maintenance solutions, supporting intelligent management throughout the entire life cycle and reducing long-term operation and maintenance costs.

[0062] Example 1

[0063] See Figure 1 and Figure 2 This invention provides a cable data acquisition system for outdoor terminal manufacturing sites, comprising:

[0064] The slide rail 10 is installed on the tower and positioned on the outside of the cable to be scanned;

[0065] Scanner 20, set on the slide rail, scans the cable to obtain raw cable data;

[0066] A drive mechanism 30 is mounted on a slide rail, and a scanner mounting base is mounted on the drive mechanism. The drive mechanism drives the scanner to rotate along the slide rail.

[0067] The microprocessor 40 is used to receive the scan data from the scanner and construct a three-dimensional model of the cable based on the scan data;

[0068] VR device 50 is used to receive real-time screen projection images transmitted by a microprocessor and to remotely control the microprocessor.

[0069] The scanner 20 is connected to the drive mechanism 30 and moves along the slide rail 10 under the drive of the drive mechanism 30; the microprocessor 40 is wirelessly connected to the scanner 20 and wirelessly connected to the VR device 50.

[0070] In this embodiment of the invention, a slide rail provides the scanner's moving track, allowing the scanner to move along the slide rail to perform a comprehensive scan of the cable structure, acquiring raw cable data to provide data for constructing a 3D cable model. A drive mechanism is mounted on the slide rail, and the scanner is mounted on the drive mechanism via a scanner base. The drive mechanism drives the scanner to rotate around the cable along the slide rail, performing a comprehensive scan. The drive mechanism also drives the wireless laser scanner to perform a uniform, controllable closed-loop motion along the circular slide rail. The scanning path can accurately cover key parts such as the cable surface, joints, and insulation layer, completely solving the problems of blind spots and data loss caused by handheld scanning due to arm tremors and obstructed vision. The scanner transmits the scanned data to a microprocessor, which constructs a 3D model and sends it to a VR device. Construction personnel can project and remotely operate the 3D model by wearing a VR device, reducing the professional skill requirements for construction personnel. A single person can complete the entire process, reducing the need for personnel working at heights.

[0071] The VR device is worn by construction workers. The VR device establishes a wireless connection with the microprocessor through streaming communication. The VR device has screen projection and remote control functions. It can project the content displayed on the laptop screen onto the VR device's display interface in real time. At the same time, construction workers can remotely control the laptop through the controller that comes with the VR device.

[0072] The microprocessor establishes wireless communication connections with the scanner and the drive mechanism of the slide rail to receive the 3D data of the cable to be scanned transmitted by the scanner, and processes the received 3D data to construct the 3D model and point cloud model of the cable to be scanned.

[0073] See Figures 3 to 5 In this embodiment of the invention, the slide rail is a closed annular structure, which can be a circular ring structure, an elliptical structure, or other slide rail structures capable of omnidirectional scanning of the cable. This invention uses an annular slide rail for convenient installation and cable scanning. The slide rail 10 includes:

[0074] The track body 101 is used to provide a moving track for the scanner, and a drive mechanism is provided on the moving track; the hoisting assembly 102 is fixed on the top of the track body and is used to connect with the connecting rope hanging down from the tower to realize the hoisting and fixing of the annular slide rail on the tower.

[0075] The hoisting assembly 102 includes at least three evenly distributed hoisting rods 121. One end of each hoisting rod 121 is fixed to the annular track body 101, and the other end is equipped with a connecting buckle 122 or a connecting bolt, which is connected to the connecting rope of the tower. A rack is fixedly installed along the circumferential direction on the inner side wall of the annular track body. The three hoisting rods are evenly distributed on the top of the annular track body, with an included angle of 120° between adjacent hoisting rods. One end of each hoisting rod is welded to the track body, and the other end is equipped with a connecting buckle. The annular track can be connected to the connecting rope hanging from the tower through the connecting buckle. After hoisting, the cable to be scanned is located in the center of the annular track body. The annular track body is made of high-strength aluminum alloy, which is lightweight, high-strength, and corrosion-resistant, and can adapt to harsh outdoor environmental conditions while reducing the load on the tower.

[0076] In this embodiment of the invention, the drive mechanism 30 includes a motor 301, a gear 302, and a rack 303. The rack 303 is fixed along the track body 101. The motor 301 is mounted on the scanner mounting base. The gear 302 is fixed to the output shaft of the motor 301 and meshes with the rack 303. The rack is fixedly disposed on the inner or outer side wall of the annular track body along the circumferential direction. The motor is fixedly disposed at one end of the slide rail. The gear is fixedly connected to the output shaft of the motor, and the gear meshes with the rack. When the motor is working, it drives the gear to rotate, and the gear rolls on the rack, thereby driving the wireless laser scanner to move along the annular track body.

[0077] The drive mechanism is controlled by a handheld controller to control the start, stop, forward and reverse rotation of the drive motor, and the motor speed is maintained at 10cm / second.

[0078] The scanner 20 is a wireless laser scanner, which includes a laser scanning module 201 and a wireless communication module 202. The laser scanning module 201 is used to scan the cable to acquire raw cable data. It scans the cable by emitting a laser beam and receives the reflected laser signal to obtain the raw scan data of the cable. The wireless communication module 202 transmits the acquired raw cable data to a microprocessor. The wireless laser scanner has a scanning accuracy of no less than 0.1 mm and a scanning speed of no less than 1000 points / second to ensure rapid and high-precision acquisition of the three-dimensional data of the cable to be scanned.

[0079] In this embodiment of the invention, the VR device 50 includes:

[0080] VR glasses 501 are worn by construction workers and are wirelessly connected to a microprocessor to project the screen content of the microprocessor in real time.

[0081] The control module 502 generates control commands through the attitude sensor and touch components and transmits them to the microprocessor.

[0082] Wireless communication module 503 is used to achieve wireless communication with the microprocessor;

[0083] Power supply module 504 is used to provide operating voltage for VR glasses and control module.

[0084] The VR headset's core function is display. It integrates a display module and a power supply interface. The display module projects the laptop screen clearly in real-time, providing construction workers with an intuitive operating interface. The VR headset is physically connected to a separate controller via a double-ended Type-C data cable. This controller integrates a streaming communication module, a power supply module, and a control module. The streaming communication module enables bidirectional data transmission between the controller and the laptop, transmitting the laptop's screen signal to the VR headset's display module and simultaneously feeding back control commands to the laptop. The power supply module provides stable power to the VR headset's display module via the double-ended Type-C data cable, eliminating the need for a separate battery and reducing the weight of the headpiece. The control module includes physical buttons and a touchscreen. Construction workers perform clicks and other control operations by touching and pressing the buttons, which are then transmitted to the laptop via the streaming communication module, enabling remote control of the laptop.

[0085] The VR headset and its controller glasses are designed with high-definition display and remote control capabilities. Each pair of glasses has a resolution of 3840×1080 and a frame rate of 120Hz. They feature a built-in streaming communication module, enabling wireless communication with a laptop. Workers can use the mobile controller to translate commands into mouse movements and tap the touchscreen to perform actions such as clicking and confirming, thus remotely controlling the laptop. The VR glasses also have a built-in 5000mAh lithium battery, providing up to 4 hours of battery life, sufficient for a single high-altitude operation.

[0086] In this embodiment of the invention, the microprocessor 40 includes 3D scanning software. This software generates point clouds and 3D models, enabling the viewing, segmentation, and saving of the models, as well as monitoring the scanning status and controlling the scanning process. The microprocessor of this invention can be a laptop computer. The 3D scanning software is installed on the laptop computer for constructing the 3D model. Laptop computers are portable and convenient for on-site implementation.

[0087] Applicable.

[0088] The laptop is equipped with 3D scanning software and VR interaction software that work with the laser scanner. The data processing software is used to receive the scanning data transmitted by the wireless laser scanner and to further process the scanning data, such as point cloud stitching and 3D modeling, to construct a complete 3D model of the cable to be scanned. The VR interaction software is used to interact with VR glasses, receive control commands sent by VR glasses, and perform corresponding operations according to the control commands.

[0089] The laptop is a high-performance portable laptop equipped with an Intel Core i7 processor, 32GB of memory, and a 1TB solid-state drive, which can quickly process large amounts of scanning data. The laptop is equipped with 3D scanning software, which can generate and save point cloud data transmitted by the wireless laser scanner, and build a 3D model of the cable based on the point cloud data. The model building time is no more than 5 minutes.

[0090] See Figure 6 This invention proposes a cable data acquisition method for outdoor terminal manufacturing sites, comprising:

[0091] Step S1: The scanner mounted on the slide rail scans the cable to be scanned to obtain the raw data of the cable;

[0092] Step S2: The scanner wirelessly transmits the raw cable data to the microprocessor;

[0093] Step S3: The microprocessor constructs a 3D model of the cable based on the original cable data and sends it to the VR device;

[0094] In step S4, the VR device receives the real-time screen projection image transmitted by the microprocessor and realizes remote control of the microprocessor.

[0095] See Figure 7 The specific workflow of this invention is as follows:

[0096] Equipment installation and commissioning: Using the aerial work platform B, the construction personnel fixed the circular slide rail to the designated position on the tower A using the hoisting assembly, ensuring that the cable C to be scanned is located in the center of the circular slide rail; then, the wireless laser scanner was suspended and installed on the circular slide rail; the wireless communication connection between the VR glasses, laptop and each device was completed, and the equipment was powered on and debugged to check whether each device was working properly.

[0097] Data acquisition preparation: Construction personnel put on VR glasses and check the laptop's operating interface through the VR glasses' display to confirm that the wireless laser scanner, VR glasses, and laptop are properly connected. Then, they open the 3D scanning software on the laptop and calibrate the scanner.

[0098] Cable 3D Data Acquisition: Construction workers use VR glasses to click the "Scan Surface" button on the 3D scanning software on their laptops. The controller then sends a control signal to the drive mechanism, which starts the wireless laser scanner, moving it circumferentially along a ring-shaped slide rail. During this movement, the wireless laser scanner continuously scans the cable, acquiring raw scan data and transmitting the pre-processed data to the laptop in real time. After the wireless laser scanner completes one or more scans, acquiring complete 3D cable data and constructing a 3D model that meets the requirements, the scanning status is viewed in real time through VR glasses. Once the scan is complete, the construction workers stop the drive motor via the drive mechanism controller, and the wireless laser scanner stops moving. Then, clicking the "Scan Surface" button again initiates the model generation process on the laptop. A progress bar is displayed on the screen; when the progress bar reaches 100%, the model generation is complete.

[0099] Data storage: After the model is generated, the 3D scanning software can be remotely controlled via the VR glasses controller to save the scan project file by clicking "Save Project". Simultaneously, the 3D scanning software also provides mesh and point cloud file export capabilities. By remotely controlling the 3D scanning software via the VR glasses controller and clicking "Export Surface" and "Export Point Cloud", the scan data can be exported in mesh or point cloud format.

[0100] Step-by-step data acquisition: Based on the construction progress of the outdoor cable terminal, acquire a 3D model of the cable terminal including steps such as heating and straightening, grinding and stripping, crimping the terminals, installing stress cones, installing sleeves and top components, and repeat the scanning steps 3 and 4 above.

[0101] Completion and Equipment Recycling: After the 3D model acquisition is completed, the construction personnel will turn off the power to all equipment, dismantle the circular slide rail, wireless laser scanner, and other equipment, and then recycle and organize them.

[0102] The cable data acquisition system for outdoor terminal fabrication sites provided by this invention has the following advantages:

[0103] 1. To address the issues of limited space and equipment fall risk in high-altitude operations, safety protection has been upgraded:

[0104] This solution achieves physical separation between the control terminal and the high-altitude work site through wireless communication between VR glasses and a laptop. The laptop can be placed in a safe area on the ground, and construction personnel can remotely operate the equipment using only lightweight VR glasses. This design not only solves the problem of unstable placement of control equipment on narrow high-altitude platforms, but also eliminates the risk of the laptop falling from a height due to collisions or shaking. This protects equipment assets and eliminates safety threats to personnel and facilities on the ground, complying with the safety regulations for high-altitude operations in the power industry.

[0105] 2. To address the safety hazards and physical exertion associated with manual handheld scanning, and to reduce the risks to personnel during operation:

[0106] Driven by an automated circular slide rail and drive mechanism, the wireless laser scanner can move autonomously along the circumference of the cable, eliminating the need for construction personnel to frequently move the equipment on the high-altitude platform or lean out to avoid obstructions. Simultaneously, it relieves the physical burden of holding heavy equipment for extended periods, effectively reducing worker fatigue and decreasing the risk of falls from heights caused by fatigue or loss of balance, significantly improving operational safety and personnel comfort.

[0107] 3. To address the issues of unstable manual scanning trajectories and blind spots, achieve accurate data collection across all dimensions:

[0108] The drive mechanism propels the wireless laser scanner in a uniform, controllable closed-loop motion along a circular slide rail. The scanning path accurately covers key areas such as cable surfaces, joints, and insulation layers, completely eliminating blind spots and data loss caused by handheld scanning due to arm tremors and obstructed vision. Combined with the hardware performance of the wireless laser scanner, which boasts a scanning accuracy of no less than 0.1mm, it can acquire high-density, low-error point cloud data, ensuring the integrity and continuity of subsequent 3D modeling.

[0109] 4. Significantly improves operational efficiency by addressing the inefficiency caused by repeated sweeping:

[0110] The automated closed-loop scanning mode can acquire complete data of the entire circumference of the cable in a single scan, eliminating the need for repeated manual adjustments and rescanning, thus shortening the single acquisition time and improving operational efficiency. Simultaneously, the real-time monitoring and remote control functions of the VR glasses, combined with the integrated "acquisition-processing-modeling" workflow of the laptop, significantly shorten the data delivery cycle and optimize the work process.

[0111] 5. Addressing the issue of wired scanning equipment entanglement, adaptable to complex high-altitude environments:

[0112] The system's wireless laser scanner, VR glasses, and laptop all use wireless communication technology to transmit data and instructions, abandoning the traditional wired connection method. This fundamentally avoids data interruption and equipment damage caused by cables getting tangled and knotted with poles and towers during the scanning process, making it suitable for working environments with multiple cables and complex pole structures at high altitudes.

[0113] 6. Addressing the issues of high operational barriers and maintenance costs, facilitating the implementation of intelligent management:

[0114] VR glasses utilize a visual interface and controller operation logic, reducing the professional skill requirements for construction personnel. A single person can complete the entire operation, reducing the need for personnel working at heights. Simultaneously, high-precision 3D models and point cloud data can be directly used for digital archiving of cable terminals, fault tracing, and optimization of maintenance solutions, supporting intelligent management throughout the entire lifecycle and reducing long-term maintenance costs.

[0115] The above description has been given for purposes of illustration and description. Furthermore, this description is not intended to limit the embodiments of the invention to the forms disclosed herein. Although numerous exemplary aspects and embodiments have been discussed above, those skilled in the art will recognize certain variations, modifications, alterations, additions, and sub-combinations thereof.
