[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Figure 1 A schematic diagram of a warning device for prohibiting fishing on a power transmission line provided by an embodiment of the present invention, see Figure 1 , including: an alarm module 110, a sensing module 120, a control module 130 and a mounting bracket;

[0042] The alarm module 110, the sensing module 120 and the control module 130 are mounted on a mounting bracket;

[0043] The sensing module 120 is connected to the control module 130; the control module 130 is connected to the alarm module 110;

[0044] The sensing module 120 is used to collect image information of a preset area on the transmission line, detect and identify the image information, obtain intermediate image information, and then identify the fishing rod image according to the intermediate image information, and send a control signal to the control module 130 if the fishing rod image is detected;

[0045] The control module 130 is used to send an alarm signal according to the control signal, and the alarm module 110 performs an audible and visual alarm according to the alarm signal.

[0046] Specifically, the mounting bracket may include a steel anchor portion and a straight rod portion. Part of the steel anchor portion is inserted into the ground to fix the portion. The portion of the steel anchor portion exposed above the ground is connected to the straight rod portion. The straight rod portion is used to carry and install the alarm module 110, the sensing module 120 and the control module 130.

[0047] The sensing module 120 can collect image information of a preset area, and the preset area can be the area where the power transmission lines passing through the water area are located. Exemplarily, the image acquisition function of the sensing module 120 is implemented by an imaging unit and other devices. For example, the visible light imaging unit can be a visible light camera device, and the visible light camera device can collect image information of visible light. The infrared imaging unit can be an infrared camera device, and the infrared camera device can collect image information of infrared light. The image information includes a power transmission line, which is shown as a straight line feature. If there is a fishing rod, the fishing rod also shows a straight line feature in some cases. Therefore, if the sensing module 120 directly detects and identifies the image information, it is easily affected by the power transmission line, resulting in a false alarm. Therefore, the sensing module 120 detects and identifies the image information to identify the straight line features in the image information, detects the part of the image that is close to the straight line, and obtains the intermediate image information. Then, the feature points of the intermediate image information are image recognized again to obtain more accurate detection, thereby improving the accuracy of the detection. When a fishing rod is detected in the image information, it means that there is a fisherman in the preset area. The sensing module 120 sends a control signal, the control module 130 sends an alarm signal according to the control signal, and the alarm module 110 performs sound and light alarm according to the alarm signal. For example, when the alarm module 110 triggers the alarm, a flash alarm and a voice broadcast are issued, such as "High voltage danger, beware of electric shock! Fishing near high voltage lines is strictly prohibited" and the like.

[0048] The technical solution provided by the embodiment of the present invention detects and identifies the image information by setting the sensing module 120, using image recognition to identify the straight line features in the image information, and detects the part of the image that is close to the straight line to obtain the intermediate image information. Then, the image recognition is performed again on the feature points of the intermediate image information to obtain more accurate detection, thereby improving the accuracy of the detection and achieving effective monitoring. When the image information corresponding to the fishing rod is detected, the alarm module 110 is activated, thereby reducing energy waste in non-hazardous situations.

[0049] Optional, Figure 2 A schematic diagram of the structure of another transmission line fishing prohibition warning device provided by an embodiment of the present invention, see Figure 2 , the sensing module 120 includes at least one visible light imaging unit 121 and a first recognition unit 122;

[0050] The visible light imaging unit 121 is connected to the first recognition unit 122; the first recognition unit 122 is connected to the control module 130, and the visible light imaging unit 121 is used to collect visible light type image information of a preset area on the transmission line;

[0051] The first recognition unit 122 includes a first detection model subunit 1221 and a second detection model subunit 1222; the first detection model subunit 1221 is used to detect the straight line part in the image information based on the first detection model to obtain the intermediate image information, and the second detection model subunit 1222 is used to recognize the fishing rod image in the intermediate image information based on the second detection model.

[0052] Specifically, the visible light imaging unit 121 may be a visible light camera, which collects visible light type image information. In some embodiments, the sensing module 120 includes two visible light imaging units 121. Figure 3 A schematic diagram of the structure of another transmission line fishing prohibition warning device provided by an embodiment of the present invention, see Figure 3 , through a group of visible light imaging units 121, a binocular imaging system is formed to make it easier to judge the distance between the fishing rod and the transmission line. The first recognition unit 122 is an image processing unit. The first detection model subunit 1221 performs a recognition process on the image information based on the first detection model to obtain intermediate image information with straight line part features of the image information. Exemplarily, the first detection model can adopt the Hough Transform model, which detects the shape by searching for the local maximum value of the straight line in the accumulator of the parameter space. For example, by finding each point on the straight line in the image, for each feature point, many straight lines are found through this point, and each straight line has a corresponding parameter value (such as parameters such as angle and distance). In the parameter space, all the straight line parameter values ​​that may pass through the feature point are accumulated, and the straight line with the largest cumulative value in the parameter space is found, which is the straight line in the image. The remaining feature points that coincide with the found straight line also belong to the straight line, and other straight lines are found in the remaining feature points. The main steps of the Hough Transform model include edge detection, which is used to detect the straight line feature points in the image (maximum in the same part, minimum in the same part, increasing points, etc.). Detect straight lines and detect local maximum points with large voting numbers in the parameter space. The parameter values ​​corresponding to these points are the parameters of the straight lines in the image. Connect the feature points that meet the requirements to form intermediate image information with a straight line image.

[0053] The second detection model subunit 1222 recognizes and processes the intermediate image information based on the second detection model to detect whether the image information has a fishing rod. This allows for more accurate detection, thereby improving the accuracy of detection. Exemplarily, the second detection model can use a convolutional neural network (CNN) model. The CNN model processes a feedforward neural network of image data. It extracts local features of the image by sliding various convolution kernels on the image, and then superimposes them layer by layer to finally obtain complex graphic features. Exemplarily, Figure 4 A processing flow chart of a second detection model subunit is provided, see Figure 4 , S110, input the intermediate image information of a preset size into the input layer of the CNN model. Exemplarily, the preset size uses image information of size 416x416 pixels. S120, use ResNet-50 as the backbone network of the model. ResNet-50 is a deep neural network that can be used for various computer vision tasks. By using ResNet-50 as the backbone network, the feature representation of the image can be extracted from it and then input into other networks to achieve more complex tasks to achieve optimal performance and accuracy. S130, construct a feature pyramid based on ResNet-50 using a feature pyramid network, combine the semantic information of high-level feature maps with the precise location information of low-level feature maps through top-down paths and lateral connections, and merge feature maps from different levels of the backbone network to detect fishing rods from different scales, thereby improving the accuracy of the network model in detecting fishing rods. S140. For each scale, a 1x1 convolution layer is used to predict the category probability and the confidence of each bounding box, a 3x3 convolution layer is used to predict the coordinates of the bounding box, and the category, confidence, and coordinates of each bounding box are output through the output layer.

[0054] Exemplarily, the production of the fishing rod data set is through on-site shooting, network search, video surveillance and other methods to collect pictures of people carrying fishing rods near the transmission lines. A total of 30,886 photos were collected under different weather conditions, times (such as daytime and dusk), different distances and angles. The collected image data are annotated using the LabelImg target detection data annotation tool. The main annotation content is the location where the fishing rod appears in the image, including the center point, height, width of the annotation box, and its category is a fishing rod. The annotated data set is enhanced using random flipping, rotation, scaling and other transformation methods, and a small number of pictures without fishing rods are added to enhance its robustness. Finally, 154,430 annotated images were obtained, of which 92,658 pictures were randomly selected as training sets, 30,886 as test sets, and the remaining images as verification sets.

[0055] In the training process of the CNN model for fish rod image recognition, the initial learning rate is set to 0.001, and the learning rate is divided by 10 after every 40 iterations, for a total of 100 training iterations. The batch size is set to 64, the optimizer is AdamW, the activation function is ReLU, and the loss function is cross entropy and mean square error, so as to ensure that both regression loss and classification loss are taken into account, and improve the confidence score of the network model and the accuracy of target detection. After training, the model can finally achieve an accuracy of more than 90% on the validation set. The loss function of its training process is as follows: Figure 5 As shown in the figure, it can be seen that when the iteration number reaches 80, the change curve of the loss function is basically close to convergence.

[0056] As an optional embodiment, Figure 6 A schematic diagram of a structure of another transmission line fishing prohibition warning device provided by an embodiment of the present invention, combined with Figure 3 , see Figure 6 , the sensing module 120 includes at least one visible light imaging unit 121, at least one infrared imaging unit 123, a first recognition unit 122 and a second recognition unit 124;

[0057] The visible light imaging unit 121 and the infrared imaging unit 123 are both connected to the second recognition unit 124, and the second recognition unit 124 is connected to the first recognition unit 122;

[0058] The visible light imaging unit 121 is used to collect visible light image information of a preset area on the transmission line;

[0059] The infrared imaging unit 123 is used to collect infrared image information of a preset area on the transmission line;

[0060] The second recognition unit 124 is used to obtain fused image information according to the visible light image information and the infrared image information;

[0061] The first recognition unit 122 includes a first detection model subunit 1221 and a second detection model subunit 1222; the first detection model subunit 1221 is used to detect the straight line part in the image information based on the first detection model to obtain the intermediate image information, and the second detection model subunit 1222 is used to recognize the fishing rod image in the intermediate image information based on the second detection model.

[0062] Specifically, the sensing module 120 is provided with a visible light imaging unit 121 and an infrared imaging unit 123, wherein the infrared imaging unit 123 may be an infrared camera device, which can collect infrared light image information. Under bad weather conditions such as night, heavy rain, fog or snow, it is usually difficult for a visible light camera device to accurately obtain a target image, while an infrared camera device can more accurately identify a human body. Therefore, visible light image information is collected by the visible light imaging unit 121, and infrared image information is collected by the infrared imaging unit 123. The second recognition unit 124 fuses the visible light image information and the infrared image information based on the visible light image information and the infrared image information, so as to improve the accuracy of detecting fishing rods at night and in bad weather. Exemplarily, Figure 7 For a flow chart of the second identification unit processing process provided in an embodiment of the present invention, see Figure 7 , S210, according to the scale invariant feature transform matching algorithm (SIFT), the feature points of the visible light image information and the infrared image information are detected respectively, S220, the brute force matching algorithm is used to register the detected feature points, S230, the random sample consensus algorithm (RANSAC) is used to screen the registered feature points and calculate the transformation matrix, and the boundary of the object to be identified can be calculated through the transformation matrix. S240, based on the transformation matrix, the feature transformation of the infrared image information is performed, and the Poisson fusion algorithm is used to fuse the visible light image information and the infrared image information to obtain the fused image information.

[0063] The first detection model subunit 1221 performs a recognition process on the fused image information based on the first detection model to obtain intermediate image information with straight line features. The second detection model subunit 1222 performs a recognition process on the intermediate image information based on the second detection model to detect whether the image information has a fishing rod. This allows for more accurate detection, thereby improving the accuracy of detection.

[0064] Based on the above embodiments, Figure 8 A schematic diagram of the structure of another transmission line fishing prohibition warning device provided by an embodiment of the present invention, see Figure 8 , the warning device for prohibiting fishing on power transmission lines also includes at least one infrared sensor module 140; the sensor module 120 also includes a driving unit 150;

[0065] The infrared sensor module 140 is connected to the driving unit 150; the driving unit 150 is connected to the visible light imaging unit 121 and the infrared imaging unit 123 respectively;

[0066] The infrared sensor module 140 is used to collect heat source information in a preset area;

[0067] The driving unit 150 is used to drive the visible light imaging unit 121 and the infrared imaging unit 123 to obtain image information in the direction of the heat source information according to the heat source information.

[0068] Specifically, in order to improve the real-time detection, the sensing module 120 usually needs to be powered on for a long time, which also increases the power consumption of the warning device. The warning device is usually set outdoors, and it is difficult to ensure its normal function when only using batteries and solar panels. Therefore, by setting at least one infrared sensing module 140 on the warning device, the infrared sensing module 140 can use an infrared sensor, and the infrared sensor can sense the heat source. Therefore, in the case of poor detection field of view, the infrared sensor can be used to scan and detect the preset area. When the infrared sensing module 140 detects heat source information in the preset area, the driving unit 150 can drive the visible light imaging unit 121 and the infrared imaging unit 123 according to the direction and position of the heat source information to obtain image information in this direction. Therefore, there is no need for the sensing device to detect the preset area at all times, thereby reducing the working time of the sensing device and reducing the working energy consumption.

[0069] When the infrared sensor module 140 does not collect heat source information within a period of time, the driving unit 150 can also send a sleep signal to the visible light imaging unit 121 and the infrared imaging unit 123. The visible light imaging unit 121 and the infrared imaging unit 123 enter the standby state according to the sleep signal, thereby further reducing the working energy consumption of the warning device.

[0070] Optionally, the warning device for prohibiting fishing on power transmission lines also includes a direction adjustment ring, Fig. 9 A schematic diagram of a direction adjustment ring according to an embodiment of the present invention is shown in FIG. Fig. 9 The direction adjustment ring includes a coaxial inner ring 310 and an outer ring 320, the inner ring 310 is installed on the mounting bracket, and the infrared sensor module 140 is arranged on the outer ring 320; the outer ring 320 can rotate around the inner ring 310, and the inner ring 310 includes a plurality of slots 330, and the slots 330 are distributed along the circumferential direction of the direction adjustment ring; the infrared sensor module 140 uses the slots 330 to relatively fix the positions of the inner ring 310 and the outer ring 320.

[0071] Specifically, in the embodiment of the present invention, taking the inner ring 310 as an example, two of the three slots 330 are arranged opposite to each other, and the other is on the midline of the line connecting the two slots 330. The infrared sensor module 140 is arranged on the outer ring 320, and the line between the detection signal output end of the infrared sensor module 140 and each slot 330 can form three detection directions. When the outer ring 320 rotates coaxially around the inner ring 310, the output direction of the infrared sensor module 140 also rotates accordingly. After the infrared sensor module 140 is adjusted to a suitable position, it can be fixed by the slot 330, for example, by clamping, hanging, etc., so that the positions of the inner ring 310 and the outer ring 320 are relatively fixed. That is, the detection direction of the infrared sensor module 140 is fixed.

[0072] Optionally, the vertical projection of the infrared sensor module 140 on the ground is at least 5 meters away from the fishing water source. Specifically, through the development of the ROS system of the Jetson nano control board, the risk point is determined based on the trajectory control algorithm of the model predictive control (MPC). The risk point is the point where the fisherman, fishing rod, fishing line, etc. are not close enough to the high-voltage line. When the distance is insufficient, the arc will break through the air and discharge, causing electric shock to personnel. In the case of a 110kV transmission line, the risk point should be no less than 1.5 meters from the transmission line, in the case of a 220kV transmission line, the risk point should be no less than 3 meters from the transmission line, and in the case of a 500kV transmission line, the risk point should be no less than 5 meters from the transmission line. Therefore, by limiting the distance between the vertical projection of the infrared sensor module 140 on the ground and the fishing water source to at least 5 meters, the detection of fishing rods within the risk point range can be achieved to avoid safety hazards. Fig.10 A top view schematic diagram of a warning device arrangement provided by an embodiment of the present invention, see Fig.10 , warning devices 410 are installed directly below and on both sides of the transmission line 420. The infrared sensor module 140 can be arranged on the warning device 410. The distance between the warning device 410 directly below and the riverside is at least 5 meters, and the infrared sensor module 140 covers the detection of the nearby area. The distance between the warning device 410 on the side and the side of the transmission line 420 is d2, d2 is 5 meters, and the distance between the warning device 410 on the side and the riverside is d3, d3 is 10 meters. The warning device 410 directly below the transmission line 420 is closer to the shore of the water area and serves as the main warning device. The warning devices 410 on both sides serve as auxiliary warning devices, so that the sensor detection range completely covers the water area crossed by the transmission line 420.

[0073] Optional, combined Figure 3, a warning device for prohibiting fishing on power transmission lines, further includes a power supply module 430, which is used to supply power to the alarm module 110, the sensing module 120 and the control module 130. Specifically, the power supply module 430 may include a solar power supply unit and a replaceable energy storage battery unit, and the solar power supply unit collects solar energy and converts it into electrical energy, and stores the electrical energy in the energy storage battery unit. The energy storage battery unit can discharge outward to supply power to the alarm module 110, the sensing module 120 and the control module 130. The power supply module 430 may also include a direct power supply unit, which is connected to an external power supply through a line, and the external power supply supplies power to the warning device 410 through the direct power supply unit.

[0074] Optionally, the warning device for prohibiting fishing on power transmission lines also includes a luminous warning sign 440, which is arranged on a mounting bracket and is used to self-luminously display warning information. Specifically, the luminous warning sign 440 can be made of high-efficiency luminous materials, has a long continuous light time and good visibility, and can effectively display warning information at night, such as "High voltage danger, fishing is strictly prohibited", etc., to enhance the warning effect.
