Description

Technical Field

[0001] This invention relates to the field of transmission line tower attitude monitoring technology, specifically to a transmission line tower attitude monitoring device and method based on the center frame difference method. Background Technology

[0002] Monitoring the attitude of transmission line towers and the distance between the towers and the tree line is a crucial aspect of the State Grid Corporation of China's efforts to improve the intelligent operation and maintenance of transmission lines. It plays a positive role in promoting the construction of my country's new power system. In recent years, with the increasing scale of my country's power grid, transmission lines are inevitably erected in mountainous areas with complex terrain. Affected by factors such as earthquakes, geological vibrations in mining areas, and extreme weather, transmission towers may experience slight tilting or displacement. Furthermore, as trees grow year by year, the distance between the towers and the tree line gradually decreases, easily leading to potential faults such as conductor-to-tree discharge. The main technology used for monitoring the attitude of transmission line towers and the distance between the towers and the tree line is machine vision technology. The center frame difference method is a method for monitoring the displacement of moving targets by differentiating the displacement of target pixels in the current frame image and the initial frame image in a video sequence. Its basic idea is: the pre-acquired and stored initial frame image is used as a background model; the current frame image is differiated from the background model to extract the displacement of the moving target.

[0003] Traditional monitoring methods for the attitude of transmission line towers and the distance between trees and lines require manual on-site measurement with instruments, which results in a large workload for users, is time-consuming and labor-intensive, and manual inspection of transmission lines in mountainous areas further increases the difficulty and cost of monitoring. Summary of the Invention

Manual inspection of transmission lines in mountainous areas further increases the difficulty and cost of monitoring. This solution eliminates the need for manual on-site measurement with instruments, reducing the user's workload and improving efficiency. It is particularly suitable for inspecting transmission lines in mountainous areas, significantly reducing working time and difficulty, and lowering monitoring costs. Furthermore, this device can clean the camera lens, preventing inaccurate data due to unclear camera data, reducing errors, and improving the monitoring accuracy.

The control end of the hot air blower is electrically connected to the controller to facilitate the drying of the lens of the acquisition camera.

[0013] The monitoring method of this device:

[0014] Step 1: Angle adjustment. The user first installs the device in the desired position. At this time, the distance detection sensor can monitor the height of the acquisition camera, the photovoltaic charging panel can charge the battery, and the controller can transmit data and control the operation of the device. The first motor causes the first worm gear to drive the first worm wheel, the first rotating rod, the acquisition camera, the second rotating rod, and the angle detector to rotate.

[0015] Step 2: Data acquisition. The camera can collect data on the posture of the transmission line towers and the distance between the towers and the tree line. The data is then transmitted to the central control console for analysis.

[0016] Step 3: Collect rainwater. When it rains, the filter screen can filter out impurities in the rainwater, and the filtered rainwater is stored inside the collection tank.

[0017] Step 4: Cleaning. When the video or photos captured by the camera are unclear, the first motor is used to level the camera, and the second electric push rod is used to shorten the cleaning sleeve in the middle of the protective cleaning cover to cover the lens of the camera. Then, clean water from the cleaning water tank is introduced into the liquid chamber and finally sprayed onto one end of the camera through the spray nozzle. The lens of the camera is cleaned by the third motor and the cleaning brush.

[0018] Step 5: Drying process. After cleaning, the hot air generated by the hot air blower is introduced into the air chamber through the air pipe, and finally sprayed onto one end of the acquisition camera through the air hole, thereby drying one end of the acquisition camera.

[0019] Step Six: Prepare the water source. When the level sensor detects that the water level inside the cleaning water tank is too low, the upper middle part of the water collection tank is pumped into the cleaning water tank through the second water pump and the second water pipe for the next use.

[0020] Step 7: Self-adjustment. If the device is tilted or deflected, the contact will move in the direction of the tilt. The contact and the detection plate will enable the corresponding first electric push rod to work. The extension of the first electric push rod will push the bottom of the corresponding acquisition box upward, so that the contact is between the detection plates, ensuring that the contact no longer contacts the detection plates, and ensuring that the data processing error of the acquisition camera is within the range.

[0021] Step 8: Flexibility adjustment. The user controls the second motor to operate, which rotates the coil via the second worm and the second worm wheel. By controlling the length of the control wire, the height of the contact can be controlled, thereby controlling the sensitivity of the device's offset and tilt monitoring.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1) The controller enables data transmission and controls the operation of this device. The extension of the second electric push rod opens the protective cleaning cover, which shields the acquisition camera from sunlight, ensuring video and photo capture while minimizing the impact of sunlight. The user controls the first motor, causing the first worm gear, first worm wheel, first rotating rod, acquisition camera, second rotating rod, and angle detector to rotate. The angle detector monitors the direction and angle of the camera's rotation. After positioning the acquisition camera at a suitable angle using the first motor, first worm gear, first worm wheel, and first rotating rod, the camera can collect data on the posture of transmission line towers and the distance between the towers and the tree line. The controller then transmits the data to the main control console for analysis, determining whether the monitored transmission line tower posture is within the normal range and whether it affects power transmission. This eliminates the need for manual on-site measurement of transmission line tower posture and tree line distance, reducing user workload and increasing efficiency. It is particularly suitable for inspecting transmission lines in mountainous areas, significantly reducing working time and difficulty, and also lowering monitoring costs.

[0024] 2) When it rains, the filter screen can filter out impurities in the rainwater. The filtered rainwater is stored inside the water collection tank. When the video or photos captured by the camera are unclear, the user controls the first motor and the second electric push rod to work. The first motor makes the camera horizontal, and then the cleaning sleeve in the middle of the protective cleaning cover is put on the lens of the camera. The cleaning brush is in contact with one end of the camera. The first water pump and the first water pipe input clean water from the cleaning water tank into the liquid chamber. Finally, the water is sprayed onto one end of the camera through the spray hole. The third motor drives the cleaning brush to rotate, and the cleaning brush can clean one end of the camera, thereby cleaning away the dirt on one end of the camera.

[0025] 3) The hot air generated by the hot air blower is introduced into the air chamber through the air pipe, and finally sprayed onto one end of the acquisition camera through the air hole, thereby drying one end of the acquisition camera and preventing water stains from adhering to the end of the acquisition camera and causing unclear data acquisition again, reducing errors and improving accuracy. After cleaning and drying, the protective cleaning cover is opened by extending the second electric push rod, and the end of the acquisition camera is shaded again.

[0026] 4) When the level sensor detects that the water level inside the cleaning water tank is too low, the level sensor controls the second water pump to work. The second water pump and the second water pipe will input the clean water from the upper middle part of the collection tank into the cleaning water tank for the next use. This ensures that the device does not need to worry about the water source. After long-term use of the device.

[0027] 5) If the device is tilted or deflected, the contact will move in the direction of the tilt. When the contact is in contact with the detection plate, the first electric push rod corresponding to the detection plate will work. The first electric push rod will extend and push the bottom of the acquisition box at the corresponding position upward, so that the contact is between the detection plates and the detection plate. This ensures that the contact is no longer in contact with the detection plate, thus ensuring that the detection rod, acquisition box and acquisition camera are always in a vertical state and that the data processing error of the acquisition camera is within the range. The first ball groove and the first ball rod can increase the movement space between the detection rod and the mounting rod and improve its self-adjustment flexibility. The second ball groove and the second ball rod can ensure the flexibility of the first electric push rod during adjustment and make the operation of the first electric push rod more convenient.

[0028] 6) The user controls the second motor to work. The second worm and the second worm wheel can make the coil rotate. By controlling the length of the control wire, the height of the contact can be controlled, thereby controlling the sensitivity of the device to monitor the offset and tilt. The user can adjust the sensitivity of the device to adjust the offset and tilt according to the usage environment and usage requirements, further improving the scope of use of the device.

[0029] This device eliminates the need for manual on-site measurement, reducing user workload and increasing efficiency. It is particularly suitable for inspecting power transmission lines in mountainous areas, significantly reducing working time and difficulty, and lowering monitoring costs. Furthermore, the device can clean the camera lens, preventing inaccurate data due to unclear image quality, thus reducing errors and improving monitoring accuracy. It also features automatic self-adjustment to prevent data inaccuracy caused by tilting or shifting over time, further enhancing data accuracy and reducing monitoring errors.

This allows the system to determine whether the monitored transmission line tower posture is within the normal range and whether it affects power transmission. Furthermore, when monitoring the posture of the transmission line towers and the distance between the towers and the tree line, there is no need for manual on-site measurement with instruments, thus reducing the user's workload and improving efficiency.

One end of the second water pipe 50 passes through the collection box 1 and connects to the cleaning water tank 35. A second water pump 51 is installed in the middle of the second water pipe 50. The collection box 1 is also equipped with a drying mechanism for drying the lens of the acquisition camera 5. The protective cleaning cover 33 can be opened by extending the second electric push rod 34. The protective cleaning cover 33 can provide shade for the acquisition camera 5, ensuring that the acquisition camera 5 can collect videos and photos and reducing the impact of sunlight on the acquisition camera 5. When it rains, the filter screen 49 can filter out impurities in the rainwater. The filtered rainwater is stored inside the water collection tank 48. When the video or photos collected by the acquisition camera 5 are unclear... At this time, the user controls the first motor 13 and the second electric actuator 34 to work. The first motor 13 drives the first worm gear 12 to rotate, which in turn drives the first worm wheel 11 and the first rotating rod 10 to rotate. The first rotating rod 10 drives the acquisition camera 5 to rotate. The user rotates the acquisition camera 5 to a horizontal position, and at the same time, the second electric actuator 34 shortens, causing the protective cleaning cover 33 to reset. This allows the cleaning sleeve 37 in the middle of the protective cleaning cover 33 to be placed on the lens of the acquisition camera 5, so that the cleaning brush 40 is in contact with one end of the acquisition camera 5. At this time, the first water pump 47 starts, and clean water from the cleaning water tank 35 is input into the liquid chamber 44 through the first water pump 47 and the first water pipe 46. Finally, the clean water is sprayed onto one end of the acquisition camera 5 through the spray nozzle 45.To facilitate cleaning of the acquisition camera and ensure the accuracy of data acquisition, when the level sensor 38 detects that the water level inside the cleaning water tank 35 is too low, the level sensor 38 controls the second water pump 51 to operate. The second water pump 51 and the second water pipe 50 then pump clean water from the upper part of the collection tank 48 into the cleaning water tank 35 for future use, thus ensuring that this device does not need to worry about water supply issues.

[0045] Please see Figure 3 and Figure 7 In this embodiment, the rotating brush mechanism includes a third motor 39 and a cleaning brush 40. The third motor 39 is located in the middle of the cleaning sleeve 37, and the cleaning brush 40 is rotatably connected to the bottom end of the cleaning sleeve 37. The middle part of the cleaning brush 40 is fixedly connected to the output end of the third motor 39. After the protective cleaning cover 33 is closed, the cleaning sleeve 37 fits against the lens of the acquisition camera 5. The cleaning brush 40 is rotated by the third motor 39. The rotating cleaning brush 40 and the sprayed clean water can clean one end of the acquisition camera 5, thereby cleaning away the dirt on one end of the acquisition camera 5. The height of the center of the cleaning brush 40 is lower than the height of its edge. The bottom end of the second water pipe 50 is five centimeters away from the inner wall of the bottom end of the water collection tank 48 to prevent the sediment at the bottom of the water collection tank 48 from being sucked away. The control end of the second water pump 51 is electrically connected to the controller 8 through the liquid level sensor 38. The control ends of the second electric push rod 34, the third motor 39 and the first water pump 47 are all electrically connected to the controller 8 to improve the cleaning effect.

[0046] Please see Figure 3 , Figure 4 and Figure 7 In this embodiment, the drying mechanism includes a hot air blower 36, an air chamber 41, air holes 42, and an air pipe 43. The air chamber 41 is located in the middle of the cleaning sleeve 37. The inner diameter of the liquid chamber 44 is larger than the outer diameter of the air chamber 41. The air chamber 41 is located in the middle of the liquid chamber 44. Air holes 42 are evenly distributed on the inner wall of one end of the air chamber 41, and one end of each air hole 42 points towards the cleaning brush 40. One end of the air chamber 41 is connected to the air pipe 43, and one end of the air pipe 43 passes through the acquisition box 1 and is connected to the output end of the hot air blower 36. The hot air generated by the hot air blower 36 is input into the interior of the air chamber 41 through the air pipe 43, and finally sprayed onto one end of the acquisition camera 5 through the air holes 42, thereby drying one end of the acquisition camera 5, preventing water stains from adhering to one end of the acquisition camera 5 and causing unclear data acquisition again, reducing errors and improving accuracy. The control end of the hot air blower 36 is electrically connected to the controller 8 to facilitate the drying of the lens of the acquisition camera 5.

[0047] It should be noted that a battery 7 is installed on the inner wall at the bottom of the acquisition box 1, and a photovoltaic charging panel 9 is installed on the top of the acquisition box 1. The output end of the photovoltaic charging panel 9 is electrically connected to the battery 7 through the controller 8. The control ends of the acquisition camera 5, the first motor 13, the angle detector 15 and the distance detection sensor 17 are all electrically connected to the controller 8. The photovoltaic charging panel 9 can charge the battery 7, improve the battery life of the device, facilitate the automatic operation of the device and provide power to the device.

[0048] The device operates as follows:

[0049] Step 1: Angle adjustment. The user first installs the device in the desired position. At this time, the height of the acquisition camera 5 can be monitored by the distance detection sensor 17, the battery 7 can be charged by the photovoltaic charging panel 9, and the controller 8 can transmit data and control the operation of the device. The first motor 13 causes the first worm gear 12 to drive the first worm wheel 11, the first rotating rod 10, the acquisition camera 5, the second rotating rod 14 and the angle detector 15 to rotate.

[0050] Step 2: Data acquisition. The camera 5 can collect data on the posture of the transmission line towers and the distance between the towers and the trees. The data is then transmitted to the main control console via the controller 8 for data analysis.

[0051] Step 3: Collect rainwater. When it rains, the filter screen 49 can filter out impurities in the rainwater, and the filtered rainwater is stored inside the water collection tank 48.

[0052] Step 4: Cleaning. When the video or photos captured by the acquisition camera 5 are unclear, the first motor 13 makes the acquisition camera 5 horizontal. The second electric push rod 34 shortens so that the cleaning sleeve 37 in the middle of the protective cleaning cover 33 is put on the lens of the acquisition camera 5. Then, clean water from the cleaning water tank 35 is input into the liquid chamber 44 and finally sprayed onto one end of the acquisition camera 5 through the spray nozzle 45. The lens of the acquisition camera 5 is cleaned by the third motor 39 and the cleaning brush 40.

[0053] Step 5: Drying. After cleaning, the hot air generated by the hot air blower 36 is introduced into the air chamber 41 through the air pipe 43, and finally sprayed onto one end of the acquisition camera 5 through the air hole 42, thereby drying one end of the acquisition camera 5.

[0054] Step 6: Prepare water source. When the level sensor 38 detects that the water level inside the cleaning water tank 35 is too low, the upper middle part of the water collection tank 48 is introduced into the cleaning water tank 35 through the second water pump 51 and the second water pipe 50 for the next use.

[0055] Step 7: Self-adjustment. When the device is tilted or deflected, the contact 29 moves in the direction of the tilt. The contact 29 and the detection plate 26 enable the corresponding first electric push rod 22 to work. The extension of the first electric push rod 22 can lift the bottom of the corresponding acquisition box 1 upward, so that the contact 29 is between the detection plates 26, ensuring that the contact 29 no longer contacts the detection plate 26, and ensuring that the data processing error of the acquisition camera 5 is within the range.

[0056] Step 8: Flexibility adjustment. The user controls the second motor 32 to work. The second worm 31 and the second worm wheel 30 can make the coil 27 rotate. By controlling the length of the control wire 28, the height of the contact 29 can be controlled, thereby controlling the sensitivity of the device to monitor the offset and tilt.

[0057] Working Principle: When using this device, the user first installs it in the desired location. The distance sensor 17 monitors the height of the acquisition camera 5. The photovoltaic charging panel 9 charges the battery 7, improving the device's battery life. The controller 8 transmits data and controls the device's operation. The second electric push rod 34 extends to open the protective cleaning cover 33, which provides shade for the acquisition camera 5, ensuring smooth video and photo capture and reducing the impact of sunlight. The user controls the first motor 13, causing the first worm gear 12 to rotate. This rotation of the first worm gear 12 causes the first worm wheel 11 to rotate. Wheel 11 drives the first rotating rod 10 to rotate, which in turn drives the acquisition camera 5, the second rotating rod 14, and the angle detector 15 to rotate. The angle detector 15 can monitor the direction and angle of rotation of the acquisition camera 5. After the user positions the acquisition camera 5 at a suitable angle using the first motor 13, the first worm gear 12, the first worm wheel 11, and the first rotating rod 10, the acquisition camera 5 can collect data on the posture of the transmission line towers and the distance between the towers and the tree line. The data is then transmitted to the main control console via the controller 8 for data analysis, thereby determining whether the posture of the monitored transmission line towers is within the normal range and whether it affects power transmission. As a result, when monitoring the posture of the transmission line towers and the distance between the towers and the tree line, it is no longer necessary to rely on manual instruments. On-site measurement reduces the user's workload and improves work efficiency, making it particularly suitable for inspecting power transmission lines in mountainous areas. It significantly reduces working time and difficulty, while also lowering monitoring costs. During rain, the filter screen 49 filters out impurities from the rainwater, which is then stored in the collection tank 48. When the video or photos captured by the acquisition camera 5 are unclear, the user controls the first motor 13 and the second electric actuator 34. The first motor 13 drives the first worm gear 12 to rotate, which in turn drives the first worm wheel 11 and the first rotating rod 10. The first rotating rod 10 then drives the acquisition camera 5 to rotate. The user rotates the acquisition camera 5 to a horizontal position, and simultaneously shortens the second electric actuator 34 to ensure proper cleaning. The cover 33 is reset, allowing the cleaning sleeve 37 in the middle of the protective cleaning cover 33 to fit over the lens of the acquisition camera 5, so that the cleaning brush 40 is in contact with one end of the acquisition camera 5. At this time, the first water pump 47 is started, and clean water from the cleaning water tank 35 is input into the liquid chamber 44 through the first water pump 47 and the first water pipe 46. Finally, the water is sprayed onto one end of the acquisition camera 5 through the spray nozzle 45. The third motor 39 drives the cleaning brush 40 to rotate. The rotating cleaning brush 40 and the sprayed clean water can clean one end of the acquisition camera 5, thereby cleaning away the dirt on one end of the acquisition camera 5. After cleaning, the hot air generated by the hot air blower 36 is input into the air chamber 41 through the air pipe 43, and finally sprayed onto one end of the acquisition camera 5 through the air hole 42.This process dries one end of the acquisition camera 5, preventing water stains from adhering to it and causing unclear data acquisition, reducing errors, and improving accuracy. After cleaning and drying, the second electric actuator 34 extends to open the protective cleaning cover 33, again shading one end of the acquisition camera 5. When the level sensor 38 detects that the water level inside the cleaning water tank 35 is too low, it controls the second water pump 51 to operate. The second water pump 51 and the second water pipe 50 pump clean water from the upper middle part of the water collection tank 48 into the cleaning water tank 35 for the next use, thus ensuring the cleanliness of the water. The device does not require a water source. After prolonged use, the device may tilt or shift. In this case, contact 29 will move in the direction of the tilt. When contact 29 comes into contact with detection plate 26, the first electric push rod 22 corresponding to detection plate 26 will activate. The first electric push rod 22 will extend and lift the bottom of the corresponding acquisition box 1 upwards, thus positioning contact 29 between detection plates 26. This ensures that contact 29 no longer contacts detection plate 26, thereby ensuring that detection rod 3, acquisition box 1, and acquisition camera 5 remain vertical. This guarantees that the data processing error of acquisition camera 5 is within the acceptable range. (The last sentence appears to be incomplete and possibly refers to a separate process involving a ball groove 18 and a ball...) Rod 19 increases the movement space between detection rod 3 and mounting rod 52, improving its self-adjustment flexibility. The second ball groove 21 and second ball rod 23 ensure the flexibility of the first electric actuator 22 during adjustment, making its operation more convenient. The user controls the second motor 32, which, through the second worm gear 31 and second worm wheel 30, causes the coil 27 to rotate. By controlling the length of the control wire 28, the height of the contact 29 can be controlled, thereby controlling the sensitivity of the device's offset and tilt. The user can adjust the device's self-offset and tilt adjustment sensitivity according to the usage environment and needs, further improving the device's usability. This device eliminates the need for manual on-site measurement, reducing user workload and increasing efficiency. It is particularly suitable for inspecting power transmission lines in mountainous areas, significantly reducing working time and difficulty, and lowering monitoring costs. Furthermore, the device can clean the lens of the acquisition camera, preventing inaccurate data due to unclear images, thus reducing errors and improving monitoring accuracy. It also features automatic self-adjustment to prevent tilting or misalignment caused by prolonged use, further enhancing data accuracy and reducing monitoring errors.
