Abstract
Description
Technical Field
[0001] This application relates to the field of live-line detection technology, and in particular to a live-line detection device for optical cable risk points. Background Technology
[0002] In today's era of rapid development in communication networks, outdoor overhead fiber optic cables act like the "neural network" of cities, permeating every corner of urban and rural areas. However, a long-overlooked yet extremely fatal safety hazard lurks in the construction and maintenance of this infrastructure: accidental electrification of overhead fiber optic cables. The root cause lies primarily in: Line crossings and shared poles: Communication optical cable lines inevitably need to cross or run parallel to power lines, or share poles with power lines, street light lines, etc. (reused poles). When power lines experience leakage or induced voltage due to insulation aging, severe weather (such as lightning strikes or strong winds causing contact with the line), construction errors, or equipment failures, the metal components of adjacent or shared communication optical cables (such as suspension wires, reinforcing cores, and metal armor layers) may become dangerously high-voltage through electromagnetic induction, electrostatic coupling, or direct contact.
[0003] Concealment and Suddenness: Electrified fiber optic cables are often difficult to detect with the naked eye, and their occurrence is sudden and unpredictable. During routine inspections, troubleshooting, line splicing, and equipment installation, installation and maintenance personnel inevitably need to come into contact with or approach fiber optic cables and related facilities (such as fiber optic distribution boxes, junction boxes, and towers). Once they touch a energized fiber optic cable or metal component, a high-voltage current instantly passes through the human body, easily causing serious electric shock injuries or even secondary accidents (such as falls from heights).
[0004] Currently, most testing devices are handheld, such as the grounding box for overhead communication optical cables disclosed in CN211179986U. These devices cannot perform continuous testing for extended periods. Therefore, there is an urgent need for a device that can perform continuous testing over a long period. Summary of the Invention

The outer edge of the rotating disk is provided with a first limiting part that keeps the first clamping member outside the first storage cavity and a second limiting part that keeps the first clamping member inside the first storage cavity. An arc-shaped transition part is provided between the first limiting part and the second limiting part.
[0010] Furthermore, the rotating disk is provided with a rotating column, and one end of the rotating column located outside the housing is provided with an installation handle. The installation handle is provided with a pin, and the housing is provided with a working position socket and a storage position socket for the pin to be inserted.
[0011] Furthermore, the housing is provided with two second storage cavities, which are located on the upper and lower sides of the first storage cavity; the second clamping member includes a sliding plate, on which a control rod is slidably mounted, and on which a plurality of circular limiting plates are spaced apart along its axial direction, and on which a mounting plate is rotatably mounted, and on which grippers are provided, and which engage with the circular limiting plates, so that when the control rod slides relative to the sliding plate, it drives the two grippers to open and close.
[0012] Furthermore, a through hole is provided through the sliding plate, and the control rod is slidably disposed through the through hole. A second spring is provided on the control rod, one end of the second spring abutting against the sliding plate and the other end abutting against the circular limiting plate; a first nut is provided on the side of the sliding plate facing away from the gripper, and the first nut is screwed onto the control rod.
[0013] Furthermore, a first sliding groove is provided on the side wall of the second storage cavity, and a second sliding groove is provided on the outer wall of the housing.

This structural design allows the device to achieve fixed installation of optical cable risk points through the clamping components, enabling long-term uninterrupted continuous detection. This fundamentally solves the industry pain point that current handheld detection devices cannot continuously monitor, and achieves real-time capture and early warning of potential electrical hazards in optical cables.

Detailed Implementation
[0021] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.
[0022] like Figure 1-13 As shown, a live-line detection device for optical cable risk points includes: The housing 6 includes a detection module 1, a signal processing module 2, a calculation module 3, an early warning module 5, a power supply module 10, and a communication module 4, all housed within the housing 6. The detection module 1, signal processing module 2, and calculation module 3 are electrically connected in sequence. The calculation module 3 is electrically connected to the early warning module 5 and the communication module 4, respectively. The power supply module 10 supplies power to all modules. The first clamping member 7 is used to engage with the track clip and is slidably embedded in the back of the housing 6; A second clamping member 8 is used for engaging with a cable or column structure, and the second clamping member 8 is slidably embedded in the back of the housing 6.
[0023] A live-line detection device for optical cable risk points includes a housing 6 as the basic support and protection structure for the entire device. Inside the housing 6, a detection module 1, a signal processing module 2, a calculation module 3, an early warning module 5, a power supply module 10, and a communication module 4 are integrated. Each functional module is electrically connected according to the logic of signal transmission and functional linkage. The detection module 1, signal processing module 2, and calculation module 3 are connected in series. The calculation module 3 is also electrically connected to the early warning module 5 and the communication module 4. The power supply module 10 provides a stable and continuous power supply to all power-consuming modules inside the housing 6, ensuring the long-term normal operation of each module.
[0024] The back of the housing 6 is slidably fitted with a first clamping member 7 and a second clamping member 8. The first clamping member 7 is specifically used to achieve a snap-fit with the track structure, while the second clamping member 8 is used to achieve a snap-fit with the cable or column structure. Both are combined with the housing 6 by a sliding embedded method.
[0025] The housing 6 provides a sealed installation space for each functional module, effectively isolating it from external environmental corrosion such as rain, dust, and ultraviolet rays, protecting internal electronic components from damage, and adapting to long-term outdoor use conditions at risk points of overhead optical cables. The series and linkage design of each functional module forms a complete working link from electric field signal acquisition, signal processing, data calculation to risk warning and remote transmission, realizing automated detection of the energized state of optical cables and completely eliminating the limitations of manual handheld detection. The two clamping components with different functions on the back specifically address the poor installation compatibility of existing detection devices. To address the issue, the first clamping component 7 is suitable for track-mounted installation scenarios such as optical distribution boxes and cabinets, while the second clamping component 8 is suitable for columnar or linear installation scenarios such as optical cable suspension wires, utility poles, and optical cable posts. The sliding embedded structure allows the clamping components to extend and retract according to installation requirements, and can be stored in the housing 6 when not in use, ensuring the overall compactness of the device. This structural design enables the device to achieve fixed installation of optical cable risk points through the clamping components, completing long-term uninterrupted continuous detection. This fundamentally solves the industry pain point that current handheld detection devices cannot continuously monitor, and enables real-time capture and early warning of potential electrical hazards in optical cables.
[0026] Furthermore, the housing 6 has a first storage cavity 70, which is set to face the interior opening of the housing 6; the bottom wall of the first storage cavity 70 is provided with a sliding post 750, and the first clamping member 7 is provided with a sliding collar 76, which is slidably sleeved on the sliding post 750.
[0027] The housing 6 has a first storage cavity 70, which opens towards the interior of the housing 6. A sliding post 750 is fixedly mounted on the bottom wall of the first storage cavity 70, and a corresponding sliding collar 76 is fixedly mounted on the first clamping member 7. The sliding collar 76 is slidably fitted onto the sliding post 750. The first storage cavity 70 provides a dedicated storage space for the first clamping member 7. The inward opening design prevents the clamping member from being damaged by external bumps or scratches when stored, and also prevents rainwater and dust from entering the interior of the housing 6 from the opening, ensuring the airtight protection of the housing 6. The sliding engagement of the sliding post 750 and the sliding collar 76 provides precise guidance for the extension and retraction of the first clamping member 7, ensuring that the first clamping member 7 always moves in a straight line during extension or retraction, avoiding problems such as jamming or displacement, and improving the motion stability of the mechanical structure.
[0028] The sliding fit structure is simple in design and has low mechanical wear, which can meet the needs of long-term outdoor use and reduce the probability of structural failure. At the same time, the sliding sleeve method makes the extension and retraction of the first clamping part 7 smooth. Installation and maintenance personnel do not need special tools when installing on site, which improves the convenience of installation and operation. In addition, the telescopic design allows the first clamping part 7 to form a whole with the housing 6 after being stored, reducing the overall size of the device and facilitating transportation and temporary placement.
[0029] Four sets of sliding columns 750 and sliding collars 76 are each provided.
[0030] Furthermore, the bottom of the first storage cavity 70 is provided with a mounting hole 75, and the sliding post 750 is disposed in the mounting hole 75; a retaining ring 777 is provided at one end of the sliding post 750 outside the mounting hole 75, and a first spring 77 is provided on the section of the sliding post 750 inside the mounting hole 75, one end of the first spring 77 abuts against the sliding collar 76, and the other end abuts against the retaining ring 777.
[0031] The mounting hole 75 provides a stable mounting base for the sliding column 750, ensuring the firm connection between the sliding column 750 and the first receiving cavity 70 and preventing the sliding column 750 from falling off during use. The retaining ring 777 provides a base for the first spring 77 to abut and support, preventing the first spring 77 from falling off the sliding column 750. The elastic structure design of the first spring 77 gives the first clamping member 7 the function of elastic reset. When the first clamping member 7 needs to be stored, the elastic force of the first spring 77 can assist the sliding collar 76 to reset along the sliding column 750, making the storage operation smoother. This structure uses the elasticity of the first spring 77 to achieve multiple functions without the need for additional reset components, simplifying the mechanical structure and reducing the production and maintenance costs of the device.
[0032] Furthermore, the bottom of the first storage cavity 70 is provided with a mounting cavity 71, and a rotating disk 72 is rotatably provided in the mounting cavity 71. The outer edge of the rotating disk 72 is provided with a first limiting part 720 for maintaining the first clamping member 7 outside the first storage cavity 70 and a second limiting part 721 for maintaining the first clamping member 7 inside the first storage cavity 70. An arc-shaped transition part 722 is provided between the first limiting part 720 and the second limiting part 721.
[0033] The bottom of the first storage cavity 70 is also provided with a mounting cavity 71. The mounting cavity 71 is rotatably provided with a rotating disk 72. The outer edge of the rotating disk 72 is integrally formed with a first limiting part 720 and a second limiting part 721. The first limiting part 720 is used to maintain the first clamping member 7 in an external state of the first storage cavity 70, and the second limiting part 721 is used to maintain the first clamping member 7 in an internal state of the first storage cavity 70. An arc-shaped transition part 722 is provided between the first limiting part 720 and the second limiting part 721.
[0034] The mounting cavity 71 provides a closed rotation space for the rotating disk 72, preventing it from being corroded by the external environment and subjected to external impacts, thus ensuring the flexibility and stability of rotation. The rotating disk 72 achieves mechanical limiting of the first clamping member 7 in its telescopic state through two limiting parts. Compared with the electrically controlled limiting structure, the purely mechanical limiting method does not require electric drive, saving energy consumption of the device. It is more suitable for outdoor use without external power supply for a long time, and the mechanical structure has a lower failure rate, making it more stable in complex outdoor environments. The first limiting part 720 is in the... When the first clamping part 7 extends out for operation, it can abut against and limit the first clamping part 7, preventing it from retracting into the storage cavity due to vibration or external force, thus ensuring the reliability of the snap-fit installation. When the clamping part is stored, the second limiting part 721 can limit its accidental extension, ensuring the structural compactness of the device during transportation and when it is idle. The arc-shaped transition part 722 between the first limiting part 720 and the second limiting part 721 makes the rotating disk 72 rotate more smoothly when switching the limiting state, without any jamming or sticking, reducing the resistance of the rotation operation and making the on-site operation of the installation and maintenance personnel more labor-saving.
[0035] Furthermore, the rotating disk 72 is provided with a rotating column 74, and the end of the rotating column 74 located outside the housing 6 is provided with an installation handle. The installation handle is provided with a pin 741, and the housing 6 is provided with a working position socket and a storage position socket for the pin 741 to be inserted.
[0036] A rotating column 74 is fixedly installed at the center of the rotating disk 72. One end of the rotating column 74 away from the rotating disk 72 extends through the housing 6 to the outside of the housing 6. An installation handle is fixedly installed at this end. A pin 741 is movably installed on the installation handle. A working position insertion hole and a storage position insertion hole are correspondingly opened on the outer wall of the housing 6. The pin 741 can be inserted into the two insertion holes.
[0037] The rotating column 74 connects the rotating disk 72 to the external mounting handle, transforming the internal rotation of the rotating disk 72 into external operation via the mounting handle. This allows installation and maintenance personnel to control the rotation of the rotating disk 72 without disassembling the housing 6, significantly improving operational convenience. The mounting handle design increases the lever arm for rotation, making it easier for installation and maintenance personnel to rotate and suitable for outdoor operation scenarios without auxiliary tools. The pin 741 engages with the two sockets to lock the rotating disk 72 in its limited position. When the first clamping member 7 extends and is held in place by the first... When the limiting part 720 is in the working state, inserting the pin 741 into the working position socket can lock the position of the rotating disk 72 and prevent it from rotating due to vibration or external force, which would cause the limiting to fail. When the first clamping member 7 is stored and limited by the second limiting part 721, inserting the pin 741 into the storage position socket can lock the rotating disk 72 and prevent the first clamping member 7 from accidentally extending. This plug-in locking structure is simple and reliable, and it is not easy to loosen when used outdoors. It can effectively ensure the stability of the limiting state and further improve the reliability of device installation and storage.
[0038] The first clamping member 7 includes a fixed plate 79 and a movable plate 791. A sliding collar 76 is disposed on the fixed plate 79. The fixed plate 79 is provided with a fixed locking hook 790, and the movable plate 791 is provided with a movable locking hook 792. The movable plate 791 is slidably disposed on the fixed plate 79. A compression spring 793 is provided between the movable plate 791 and the fixed plate 79. The compression spring 793 is used to push the movable locking hook 792 closer to the fixed locking hook 790 to achieve locking of the track.
[0039] Furthermore, the housing 6 is provided with two second storage cavities 800, which are located on the upper and lower sides of the first storage cavity 70; the second clamping member 8 includes a sliding plate 80, on which a control rod 81 is slidably provided, and on the control rod 81, a plurality of circular limiting plates are spaced apart along its axial direction. A mounting plate 84 is rotatably provided on the sliding plate 80, and a clamping claw 85 is provided on the mounting plate 84. The mounting plate 84 engages with the circular limiting plate 82 so that when the control rod 81 slides relative to the sliding plate 80, it drives the two clamping claws 85 to open and close.
[0040] The housing 6 has two second storage cavities 800, which are symmetrically arranged on the upper and lower sides of the first storage cavity 70, forming a staggered and orderly layout. The second clamping member 8 includes a sliding plate 80, on which a control rod 81 is slidably arranged. Multiple circular limiting plates are fixedly arranged on the control rod 81 at intervals along its axial direction. The sliding plate 80 also has a mounting plate 84 rotatably arranged. The mounting plate 84 is provided with grippers 85. The outer edge of the mounting plate 84 and the multiple circular limiting plates form a meshing engagement, so that when the control rod 81 slides axially relative to the sliding plate 80, it can drive the two grippers 85 to achieve opening and closing actions.
[0041] Two second storage cavities 800 provide independent storage space for the second clamping member 8, symmetrically arranged on both sides of the first storage cavity 70, making the structural layout of the back of the housing 6 more reasonable, avoiding mutual interference between the structures of the clamping members, and ensuring uniform force distribution on the back of the housing 6, thus improving the stability of the device after installation. The second clamping member 8 adopts a purely mechanical transmission structure. Through the axial sliding of the control rod 81, and the meshing of the circular limiting plate with the mounting plate 84, linear motion is converted into rotational motion of the mounting plate 84, thereby driving the gripper 85 to open and close. This motion conversion structure is ingeniously designed, has high transmission efficiency, and the purely mechanical structure does not require electronic control. With low failure rate and low energy consumption, it is suitable for long-term continuous outdoor operation. Multiple circular limit plates spaced at intervals on the control rod 81 can be used to fine-tune the engagement position of the mounting plate 84 by different pre-assembly positions, thereby adjusting the opening and closing range of the gripper 85. This allows the second clamping component 8 to adapt to cables or pole structures of different diameters, greatly improving the installation adaptability of the second clamping component 8 and meeting the clamping requirements of various installation carriers such as optical cable suspension wires of different specifications and utility poles of different diameters. The sliding plate 80 provides a unified installation base for all components of the second clamping component 8, allowing all components to form a whole and facilitating the overall extension and retraction of the second clamping component 8.
[0042] Specifically, the mounting plate 84 is rotatably mounted on the connecting rod 83, and the connecting rod 83 is connected to the sliding plate 80.
[0043] Furthermore, a through hole is provided on the sliding plate 80, and the control rod 81 is slidably disposed through the through hole. A second spring 88 is provided on the control rod 81, one end of the second spring 88 abuts against the sliding plate 80, and the other end abuts against the circular limiting plate 82. A first nut 810 is provided on the side of the sliding plate 80 facing away from the gripper 85, and the first nut 810 is screwed onto the control rod 81.
[0044] The through hole provides precise guidance for the axial sliding of the control rod 81, ensuring the straightness of the control rod 81 during sliding, avoiding failure of the meshing transmission due to offset, and improving the stability of the mechanical transmission. The elastic structure of the second spring 88 provides the control rod 81 with an automatic reset force. At the same time, the elastic force of the second spring 88 can also buffer the clamping force of the gripper 85. When vibration occurs outdoors, the elastic deformation of the spring can absorb the vibration energy, preventing the gripper 85 from loosening due to vibration and ensuring the firmness of the clamping. The threaded engagement between the first nut 810 and the control rod 81 locks the sliding position of the control rod 81. After the gripper 85 clamps the mounting carrier, tightening the first nut 810 can lock the position of the control rod 81, preventing the control rod 81 from sliding due to vibration or external force, thereby preventing the gripper 85 from loosening. The threaded locking structure is stable and reliable, and is not easy to loosen when used outdoors, further ensuring the firmness of the installation of the second clamping part 8.
[0045] Furthermore, the second storage cavity 800 has a first sliding groove 86 on its side wall and a second sliding groove 87 on its outer wall. The two ends of the sliding plate 80 are slidably disposed in the first sliding groove 86. The second sliding groove 87 has a screw 89, which extends out of the outer side of the housing 6 through the second sliding groove 87. The screw 89 has a second nut 890.
[0046] The first slide groove 86 provides guidance for the overall extension and retraction of the sliding plate 80, ensuring that the second clamping member 8 moves in a straight line during extension or retraction, avoiding deviation or jamming, and improving the stability of the movement. The second slide groove 87 cooperates with the screw 89 to form an adjustment and locking structure for the extension and retraction position of the second clamping member 8. During installation, the installation personnel only need to loosen the second nut 890 and push or pull the screw 89 on the outside of the housing 6 to drive the sliding plate 80 to slide along the first slide groove 86, adjusting the extension distance of the second clamping member 8 to adapt to different installation spaces and installation position requirements. Once the position is correct, tighten the second nut 890 to fix the position of the sliding plate 80 by thread locking, preventing it from shifting. This structural design makes the extension and retraction adjustment of the second clamping member 8 simple and convenient, requiring no special tools. The transmission method of the screw 89 enables precise adjustment of the extension distance, and the thread locking method is firm and reliable, effectively resisting the influence of outdoor vibration and ensuring the stability of the second clamping member 8 after installation. The cooperation between the first slide groove 86 and the second slide groove 87 provides dual guidance and locking for the extension and fixation of the second clamping member 8, further improving the reliability of the mechanical structure.
[0047] Furthermore, the detection module 1 includes a proximity detection chip.
[0048] The core sensing element of the detection module 1 is a proximity detection chip, which is integrated on the circuit board of the detection module 1 and electrically connected to the signal processing module 2. The proximity detection chip is a dedicated chip designed specifically for detecting power frequency electric fields at fiber optic cable risk points. It can accurately capture the power frequency electric field signal radiated by the energized metal components of the fiber optic cable in a non-contact manner, and convert this physical electric field signal into an electrical signal, which is then transmitted to the signal processing module 2. Compared with traditional contact-type voltage detection elements, non-contact detection does not require direct contact with the metal components of the fiber optic cable, fundamentally avoiding the risk of electric shock during the installation and operation of the detection device, and improving the safety of the device. At the same time, the proximity detection chip has extremely high sensitivity, which can effectively capture the weak electric field signal generated by electromagnetic induction in the fiber optic cable, promptly detect potential electrification hazards in the fiber optic cable, and avoid missed detections. The proximity detection chip is small in size and can be directly integrated into the circuit board inside the housing 6 without increasing the overall size of the device, ensuring the miniaturized design of the device and adapting to the narrow installation space at fiber optic cable risk points. In addition, the proximity detection chip also has low power consumption characteristics, which can effectively reduce the energy consumption of the detection module 1, thereby reducing the overall power consumption of the device, improving the endurance of the power supply module 10, and making it more suitable for the long-term uninterrupted continuous detection needs outdoors.
[0049] Proximity detection chips are already in use in existing technologies.
[0050] Furthermore, the calculation module 3 includes a main control chip 31, an environmental sensing unit 30, and a model storage unit 32. The environmental sensing unit 30 is electrically connected to the main control chip 31 and is used to collect parameters such as temperature, humidity, atmospheric pressure, and ambient light intensity. The model storage unit 32 stores an environmental compensation type electric field-voltage-distance calibration model.
[0051] The calculation module 3 includes a main control chip 31, an environmental sensing unit 30, and a model storage unit 32. The environmental sensing unit 30 is electrically connected to the main control chip 31. Its core function is to collect environmental parameters of the detection site in real time, including temperature, humidity, atmospheric pressure, and ambient light intensity. The model storage unit 32 is a non-volatile storage element, which pre-stores an environmental compensation type electric field-voltage-distance calibration model.
[0052] The main control chip 31, as the core computing and control component of the solution module 3, undertakes the functions of data reception, processing, and command issuance. It can quickly receive the processed electrical signals transmitted by the signal processing module 2 and perform calculation and analysis. The environmental sensing unit 30 consists of multiple sets of high-precision micro sensors, which can collect multi-dimensional environmental parameters of the detection site in real time. This solves the problem of attenuation and distortion of the electric field detection signal caused by environmental factors such as outdoor temperature, humidity, and atmospheric pressure, providing an accurate environmental data basis for subsequent calculation and compensation, and avoiding deviations in detection results due to environmental factors. The pre-stored environmental compensation electric field-voltage-distance calibration model in the model storage unit 32 is different from the traditional uncompensated linear solution. The calculation model incorporates the correlation between environmental parameters and electric field strength, voltage level, and detection distance. This allows the main control chip 31 to compensate and correct the calculation results based on the parameters collected by the environmental sensing unit 30, significantly improving the accuracy of calculating the voltage level and relative distance of the optical cable and effectively avoiding false alarms and missed alarms caused by environmental interference. The three components of the calculation module 3 are all miniaturized, low-power electronic components that can be integrated on the circuit board inside the housing 6, achieving seamless linkage with other modules. Furthermore, the non-volatile nature of the model storage unit 32 allows for long-term stable storage of calibration model data without frequent refreshes, improving the working stability of the calculation module 3 and making it suitable for long-term continuous outdoor detection.
[0053] The electric field-voltage-distance calibration model is widely used in this field and is the existing technology.
[0054] Working principle During the installation phase, firstly, select the corresponding clamping component based on the type of installation carrier at the optical cable risk point: If the installation carrier is a track structure (such as an optical distribution box or cabinet track), first pull the pin 741 on the installation handle to disengage it from the storage position socket, rotate the installation handle to drive the rotating disk 72 to rotate within the installation cavity 71, and the first limiting part 720 of the rotating disk 72 will lift the first clamping component 7 as it rotates, causing the sliding collar 76 on the first clamping component 7 to slide along the sliding post 750 to the outside of the first storage cavity 70. When the first clamping component 7 is fully extended and can be engaged with the track, insert the pin 741 into the working position socket to lock the position of the rotating disk 72, and the first limiting part 720 will maintain the extended state of the first clamping component 7. Then, engage the first clamping component 7 with the track.
[0055] If the installation carrier is a cable or pole structure (such as an optical cable suspension line or a utility pole), first loosen the second nut 890 on the second slide groove 87, push the screw 89 outside the housing 6, and drive the sliding plate 80 to slide along the first slide groove 86 to the outside of the second receiving cavity 800. After adjusting to a suitable extension distance, tighten the second nut 890 to lock the position of the sliding plate 80. Then pull the control rod 81 to make it slide axially along the through hole of the sliding plate 80. Through the meshing transmission between the circular limit plate and the mounting plate 84, the mounting plate 84 is driven to rotate and the gripper 85 is opened. After the opened gripper 85 is put into the cable / pole, tighten the first nut 810 to lock the position of the control rod 81 and prevent the gripper 85 from loosening.
[0056] After the device is installed, the power supply module 10 provides continuous and stable power to the detection module 1, signal processing module 2, calculation module 3, early warning module 5, and communication module 4 inside the housing 6, and the device enters a long-term continuous detection working state: the proximity detection chip of the detection module 1 captures the power frequency electric field signal generated by leakage current, induced current, etc. in real time by the optical cable metal component in a non-contact manner, and converts the physical signal into an electrical signal, which is then transmitted to the signal processing module 2; the signal processing module 2 performs pre-amplification, bandpass filtering, adaptive noise reduction, and other processing on the received electrical signal to filter out environmental noise. After purifying the effective signal, the processed electrical signal is transmitted to the calculation module 3. The environmental sensing unit 30 of the calculation module 3 collects environmental parameters such as temperature, humidity, atmospheric pressure, and light intensity at the detection site in real time, and transmits the parameters synchronously to the main control chip 31. The main control chip 31 substitutes the electrical signal transmitted by the signal processing module 2 into the pre-stored environmental compensation electric field-voltage-distance calibration model in the model storage unit 32, and performs calculation and compensation correction in combination with the parameters collected by the environmental sensing unit 30 to accurately calculate the approximate voltage level of the optical cable charged body and the relative distance to the device.
[0057] After the calculation is completed, the main control chip 31 transmits the calculation results synchronously to the early warning module 5 and the communication module 4. The early warning module 5 triggers the corresponding audible and visual early warning signals based on the voltage level and relative distance obtained from the calculation, reminding the surrounding installation, maintenance and inspection personnel to pay attention to the risk of the optical cable being electrified and to take timely avoidance measures. The communication module 4 remotely uploads the calculation results, device working status data, etc. to the operation and maintenance management platform to realize remote real-time monitoring of the electrified status of the optical cable risk points, so that operation and maintenance management personnel can keep abreast of the safety status of the optical cable and arrange for timely handling after discovering hidden dangers.
[0058] Throughout the entire operation, the device securely engages with different mounting carriers via the first clamping component 7 and the second clamping component 8. After fixed installation, the functional modules form an automated detection workflow, continuously collecting, processing, and calculating the electrical signals of the optical cable, and enabling on-site early warning and remote transmission. This fundamentally solves the pain point of current handheld detection devices being unable to continuously detect for extended periods. At the same time, the locking and limiting design of the mechanical clamping structure ensures the installation's robustness and structural stability under complex outdoor conditions. The low power consumption and high precision design of each electronic module ensures the device's long-term continuous operation capability and detection accuracy, enabling real-time and accurate capture and early warning of electrical hazards at optical cable risk points.
[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
