Technical Field
[0001] The invention relates to the technical field of electric power safety monitoring, and in particular to a device and method for measuring the height difference between a cable and a tree barrier. Background Art
[0002] A high-voltage transmission tower refers to a structure that supports high-voltage or ultra-high-voltage overhead transmission lines and has lightning arresters. High-voltage transmission towers are usually erected directly between villages and towns, which inevitably leads to the presence of tall trees under the transmission lines. During the long-term use of high-voltage transmission towers, the crowns of trees that grow and develop are likely to touch the transmission lines, posing certain safety hazards. Therefore, during the operation of high-voltage transmission towers, it is often necessary to use cable and tree barrier height difference measurement devices and methods to calculate the vertical distance between the cable and the top of the tree crown.
[0003] The existing cable tree barrier height difference measurement technology still has some shortcomings in actual use. The most obvious one is that it usually deploys multiple sensors to construct a spatial coordinate system, and then combines the multi-sensor results to calculate the distance between the cable and the top of the tree canopy, which requires the manual deployment of multiple sensors, consuming a lot of manpower and equipment costs; at the same time, when the equipment fails, because there are many deployed devices, it is necessary to confirm the device with error, which consumes manpower again, causing certain inconveniences to the user. For this reason, we propose a cable and tree barrier height difference measurement device and method to solve the above problems. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for measuring the height difference of cables and tree barriers, comprising a camera module, an infrared ranging module and a camera deflection module, wherein the camera module is a camera body, the infrared ranging module is an infrared rangefinder, and the number of the infrared rangefinders is two groups, and the two groups of infrared rangefinders are embedded and installed on both sides of the front end of the camera body; through the coordinated use of each module, during use, the two parts of data received by the intelligent OCR module are used to parse the high-voltage line distance and the camera deflection parameters of the high-voltage line picture from the picture, and compare them with the crown distance and the camera deflection parameters in the crown picture, and use trigonometric functions to calculate the vertical distance between the crown and the high-voltage line, and then use the angle difference between the camera deflection angle and the camera module deflection angle at the original position to estimate the x and y coordinates of the crown and the high-voltage line in the original picture.
[0006] The camera deflection module includes a mounting cantilever, a mounting seat, a gapless transmission component 1, a servo motor 1, a driving gear 1, a rotating seat, a servo motor 2, a driving gear 2, and a gapless transmission component 2. The mounting seat is fixedly mounted on the end of the mounting cantilever, and the gapless transmission component 1 is movably mounted inside the mounting seat. The top of the gapless transmission component 1 is fixedly connected with a rotating seat, and a servo motor 1 is fixedly mounted on the bottom of the mounting seat. A driving gear 1 that matches the gapless transmission component 1 is fixedly mounted on the output shaft of the servo motor 1. The driving gear 1 is driven to rotate by the servo motor 1, thereby It can drive the two groups of adjustment gears in the gapless transmission component 1 to rotate, and then drive the transmission shaft to rotate, and drive the rotating seat to rotate as a whole, so as to adjust the direction of the camera body and the infrared rangefinder. A gapless transmission component 2 is arranged on the top of the rotating seat, and a servo motor 2 is fixedly installed on one side of the rotating seat, and a driving gear 2 matched with the rotating seat is fixedly mounted on the output shaft of the servo motor 2. The driving gear 2 is driven to rotate by the servo motor 2, and then the two groups of adjustment gears in the gapless transmission component 2 can be driven to rotate, and the transmission shaft can be driven to rotate, so as to adjust the elevation angle of the camera body and the infrared rangefinder.
[0007] The gapless transmission component 1 has the same structure as the gapless transmission component 2, and the gapless transmission component 2 includes a transmission shaft and two sets of rotationally symmetrical gap adjustment structures. The transmission shaft in the gapless transmission component 2 is movably installed inside the rotating seat, and the transmission shaft in the gapless transmission component 2 is fixedly sleeved under the camera body. The bottom end of the transmission shaft in the gapless transmission component 1 is movably installed on the mounting seat, and the top end is fixedly connected to the rotating seat. The gapless transmission component 1 is vertically arranged in the mounting seat as a whole. When the active gear 1 drives the gapless transmission component 1 to move, the rotating seat can be driven to rotate synchronously, thereby realizing the adjustment of the direction of the camera body and the infrared rangefinder.
[0008] The gap adjustment structure includes an adjustment gear, a micro electric push rod, a locking friction head, a cantilever arm, a micro electric pull rod, and a self-lubricating wear-resistant bushing.

When the micro electric pull rod pulls the adjustment gear to move, the position of the micro electric pull rod itself can be adaptively adjusted to achieve smooth adjustment of the position of the adjustment gear.
[0010] As a further description of the above technical solution: a self-lubricating wear-resistant bushing is sleeved on the outside of the adjusting gear, and a plurality of connecting rods are arranged on one side of the self-lubricating wear-resistant bushing, and the connecting rods are fixedly connected to the adjusting gear by bolts. Since the active gear one or the active gear two is closely matched with the corresponding adjusting gear, self-lubrication between gear transmissions is achieved by arranging a self-lubricating wear-resistant bushing on the outside of the adjusting gear, so as to reduce wear, increase service life and ensure transmission accuracy.
[0011] As a further description of the above technical solution: the inner ring of the self-lubricating wear-resistant bushing is provided with a plurality of positioning sliders, and the peripheral side of the adjustment gear is provided with positioning grooves that cooperate with the positioning sliders. The position of the self-lubricating wear-resistant bushing can be restricted by the cooperation between the positioning sliders and the positioning grooves.

The driving gear 2 is driven to rotate by the servo motor 2, which can drive the two groups of adjustment gears in the gapless transmission component 2 to rotate, and then drive the transmission shaft to rotate, thereby realizing the adjustment of the elevation angle of the camera body and the infrared rangefinder.
[0013] As a further description of the above technical solution: the driving gear 1 is located on one side of the gapless transmission component 1, and the driving gear 1 is meshed with the adjustment gear in the gapless transmission component 1. The driving gear 1 is driven to rotate by the servo motor 1, which can drive the two groups of adjustment gears in the gapless transmission component 1 to rotate, and then drive the transmission shaft to rotate, and drive the rotating seat to rotate as a whole, so as to adjust the direction of the camera body and the infrared rangefinder.

[0034] See also Figure 1-8 In an embodiment of the present invention, a device and method for measuring the height difference between a cable and a tree barrier are provided. A device for measuring the height difference between a cable and a tree barrier comprises a camera module, an infrared ranging module and a camera deflection module. The camera module is a camera body 10, and the infrared ranging module is an infrared rangefinder 11. The number of infrared rangefinders 11 is two groups, and the two groups of infrared rangefinders 11 are embedded and installed on both sides of the front end of the camera body 10. Through the coordinated use of the camera module, the infrared ranging module, the intelligent OCR module, the camera deflection module, the tree barrier ranging module and the result feedback module, during use, the two parts of data received by the intelligent OCR module can be used to parse the high-voltage line distance and the camera deflection parameter in the high-voltage line picture from the picture, respectively, and compared with the crown distance and the camera deflection parameter in the crown picture, and the vertical distance between the crown and the high-voltage line is calculated by using trigonometric functions, and then the x and y coordinates of the crown and the high-voltage line in the original picture are estimated by the angle difference between the camera deflection angle and the camera module deflection angle at the original position, so as to realize rapid ranging of the high-voltage line and the crown.
[0035] The camera deflection module comprises a mounting cantilever 1, a mounting seat 2, a gapless transmission component 3, a servo motor 4, a driving gear 5, a rotating seat 6, a servo motor 7, a driving gear 8, and a gapless transmission component 9. The mounting seat 2 is fixedly mounted on the end of the mounting cantilever 1, and the gapless transmission component 3 is movably mounted inside the mounting seat 2. The top of the gapless transmission component 3 is fixedly connected with the rotating seat 6. The servo motor 4 is fixedly mounted on the bottom of the mounting seat 2, and the driving gear 5 that cooperates with the gapless transmission component 3 is fixedly mounted on the output shaft of the servo motor 4. A gapless transmission component 29 is provided on the top of the rotating seat 6, a servo motor 27 is fixedly installed on one side of the rotating seat 6, and a driving gear 28 matching the rotating seat 6 is fixedly mounted on the output shaft of the servo motor 27. The corresponding adjustment gear 921 is pulled by two sets of micro-electric pull rods 925 in the gapless transmission component 13 or the gapless transmission component 29 to rotate slightly, so as to eliminate the gap between the adjustment gear 921 and the driving gear 15 or the driving gear 28, thereby improving the movement accuracy of the camera module and the infrared ranging module, and further improving the accuracy of the ranging of the high-voltage line and the tree crown.
[0036] The gapless transmission component 13 has the same structure as the gapless transmission component 29. The gapless transmission component 29 includes a transmission shaft 91 and two sets of rotationally symmetrical gap adjustment structures 92. By arranging two sets of rotationally symmetrical gap adjustment structures 92 on the transmission shaft 91 and adjusting the positions of the adjustment gears 921 in the two sets of gap adjustment structures 92 slightly, the gap between the adjustment gear 921 and the active gear 15 or the active gear 28 can be eliminated, thereby improving the transmission accuracy. The transmission shaft 91 in the gapless transmission component 29 is movably installed inside the rotating seat 6, and the transmission shaft 91 in the gapless transmission component 29 is fixedly mounted under the camera body 10. The bottom end of the transmission shaft 91 in the gapless transmission component 3 is movably installed on the mounting seat 2, and the top end is fixedly connected to the rotating seat 6. The gapless transmission component 3 is vertically arranged in the mounting seat 2 as a whole. When the active gear 5 drives the gapless transmission component 3 to move, the rotating seat 6 can be synchronously driven to rotate, thereby realizing the adjustment of the direction of the camera body 10 and the infrared rangefinder 11.
[0037] The gap adjustment structure 92 includes an adjustment gear 921, a micro electric push rod 922, a locking friction head 923, a cantilever arm 924, a micro electric pull rod 925, and a self-lubricating wear-resistant bushing 926. The adjustment gear 921 is sleeved on the outside of the transmission shaft 91. A micro electric push rod 922 is fixedly installed on one side of the adjustment gear 921, and the output shaft of the micro electric push rod 922 can be inserted into the middle of the adjustment gear 921. A locking friction head 923 is fixedly installed on the end of the output shaft of the micro electric push rod 922. After adjusting the adjustment gear 921, the locking friction head 923 is driven by the micro electric push rod 922 to tighten the transmission shaft 91, ensuring that the transmission shaft 91 and the gap adjustment structure 92 can rotate synchronously, thereby further improving the stability of the gear transmission.
[0038] The cantilever arm 924 is fixedly installed on the side of the transmission shaft 91 away from the micro electric push rod 922, and the end of the cantilever arm 924 is hingedly connected with a micro electric pull rod 925, the output shaft of the micro electric pull rod 925 is hingedly connected to the adjustment gear 921, and the two ends of the micro electric pull rod 925 are hingedly connected to the cantilever arm 924 and the adjustment gear 921 respectively. When the micro electric pull rod 925 pulls the adjustment gear 921 to move, the position of the micro electric pull rod 925 itself can be adaptively adjusted to achieve smooth adjustment of the position of the adjustment gear 921.
[0039] The outside of the adjusting gear 921 is sheathed with a self-lubricating wear-resistant bushing 926. Since the active gear 1 5 or the active gear 2 8 is closely matched with the corresponding adjusting gear 921, the self-lubricating wear-resistant bushing 926 is arranged outside the adjusting gear 921 to realize self-lubrication between gear transmissions, so as to reduce wear, increase service life, and ensure transmission accuracy. The self-lubricating wear-resistant bushing 926 can be prepared by a self-lubricating and wear-resistant material in the prior art, such as a modified nylon material, and a plurality of connecting rods 927 are arranged on one side of the self-lubricating wear-resistant bushing 926. The connecting rods 927 are fixedly connected to the adjusting gear 921 by bolts, and the connecting rods 927 are installed on the adjusting gear 921 by bolts, and the self-lubricating wear-resistant bushing 926 and the adjusting gear 921 are assembled into a whole, thereby realizing the transmission function of the size.
[0040] The inner ring of the self-lubricating wear-resistant bushing 926 is provided with a plurality of positioning sliders 928, and the peripheral side of the adjusting gear 921 is provided with positioning grooves 929 that cooperate with the positioning sliders 928. The position of the self-lubricating wear-resistant bushing 926 can be restricted by cooperating with the positioning sliders 928 and the positioning grooves 929, thereby ensuring the stability of the self-lubricating wear-resistant bushing 926 and the adjusting gear 921 after assembly, thereby ensuring the transmission effect.
[0041] The driving gear 28 is located below the gapless transmission component 29, and the driving gear 28 is meshed with the adjustment gear 921 in the gapless transmission component 29. The driving gear 28 is driven to rotate by the servo motor 27, which can drive the two sets of adjustment gears 921 in the gapless transmission component 29 to rotate, and then drive the transmission shaft 91 to rotate, thereby realizing the adjustment of the elevation angle of the camera body 10 and the infrared rangefinder 11.
[0042] The driving gear 5 is located at one side of the gapless transmission component 3, and the driving gear 5 is meshed with the adjustment gear 921 in the gapless transmission component 3. The driving gear 5 is driven to rotate by the servo motor 4, which can drive the two groups of adjustment gears 921 in the gapless transmission component 3 to rotate, and then drive the transmission shaft 91 to rotate, and drive the rotating seat 6 to rotate as a whole, so as to adjust the direction of the camera body 10 and the infrared rangefinder 11.
[0043] An operating method of a cable and tree barrier height difference measuring device, further comprising: an intelligent Ocr module, wherein the input end of the intelligent Ocr module is electrically connected to a camera module and an infrared ranging module, respectively, the input end of the intelligent Ocr module is electrically connected to a camera deflection module, the input end of the camera deflection module is electrically connected to the camera module and the infrared ranging module, respectively, the output end of the intelligent Ocr module is electrically connected to an intelligent tree barrier ranging module, and the output end of the tree barrier ranging module is electrically connected to a result feedback module;
[0044] The specific steps are:
[0045] S1, the camera deflection module will move the camera module and the infrared ranging module according to the preset position confirmed by the staff through the rotating structure composed of the gapless transmission component 1 3, the servo motor 1 4, and the driving gear 1 5, and the elevation adjustment mechanism composed of the gapless transmission component 2 9, the servo motor 2 7, and the driving gear 2 8, so as to focus the camera module and the infrared ranging module on the high-voltage line and the tree crown in the picture respectively, and obtain the corresponding picture, which contains the corresponding distance information and camera deflection information;
[0046] S2. In this process, the intelligent Ocr module receives two parts of data. The first is the picture of the original position camera module, from which the position parameters of the original position camera module are parsed. The other part is two pictures sent by the camera deflection module. The high-voltage line distance and camera deflection parameters of the high-voltage line picture are parsed from the pictures, and compared with the tree crown distance and camera deflection parameters in the tree crown picture.
[0047] S3, the tree obstacle distance measurement module obtains the data of the original camera deflection angle, the high-voltage line distance, the camera deflection angle at the high-voltage line position, the tree crown distance, and the camera deflection angle at the tree crown position, and then constructs a spatial coordinate system based on these data, uses trigonometric functions to calculate the vertical distance between the tree crown and the high-voltage line, and then estimates the x and y coordinates of the tree crown and the high-voltage line in the original image through the angle difference between the camera deflection angle and the deflection angle of the original position camera module;
[0048] S4. Finally, the tree obstacle distance measurement module transmits the measured obstacle distance to the result feedback module. The result feedback module sends the obtained result parameters to the designated display terminal through the http service for result display.
[0049] In step S1, the specific deflection method of the camera body 10 is that the external controller transmits the signal to the micro electric pull rod 925 in the gapless transmission component 13 and the gapless transmission component 29 in advance, and the two groups of micro electric pull rods 925 in the gapless transmission component 13 and the gapless transmission component 29 pull the corresponding adjustment gear 921 to move, and the two rotationally symmetrical groups of adjustment gears 921 rotate in opposite directions, so that the external teeth of the two groups of adjustment gears 921 are close to the external teeth of the active gear 28 or the active gear 15, eliminating the gap in the gear transmission and improving the movement accuracy of the camera module and the infrared ranging module. After the micro electric pull rod 925 moves, the controller sends a signal to the micro electric push rod 922 to control the micro electric push rod 922 to drive the locking friction head 923 to move The transmission shaft 91 is tightened so that the transmission shaft 91 and the two sets of gap adjustment structures 92 can rotate synchronously. After the micro electric push rod 922 moves, the controller then sends a signal to the servo motor 14 and the servo motor 27 to control the servo motor 14 to drive the active gear 15 and the gapless transmission component 13 to rotate, drive the rotating seat 6 to rotate as a whole, adjust the direction of the camera body 10 and the infrared rangefinder 11, control the servo motor 27 to drive the active gear 28 and the gapless transmission component 29 to rotate, and adjust the elevation angle of the camera body 10 and the infrared rangefinder 11; because the active gear 15 or the active gear 28 is closely matched with the corresponding adjustment gear 921, the self-lubricating wear-resistant bushing 926 on the outside of the adjustment gear 921 is used to achieve self-lubrication between the gear transmissions to reduce wear.
