TECHNICAL FIELD

[0001] The present application relates to the technical field of bird repelling, and in particular to a power transmission line bird repelling method and system. BACKGROUND

[0002] With the continuous expansion of the scale of power transmission lines, their operating environment is becoming increasingly complex, and the interference problem caused by bird activities on the safe operation of the lines is becoming increasingly prominent. Especially in suburban areas, mountainous areas and ecological protection areas, power transmission lines pass through areas where birds frequently move, and birds nest and stay on tower cross arms, insulator strings and other parts, which can easily cause a series of electrical faults.

[0003] The commonly used bird repelling means at present mainly include static physical devices such as bird-proof spikes, reflective sheets and wind-driven bird repellers, or single acoustic means such as ultrasonic waves and directional sound. These means have certain repelling effect in the initial stage, but they are difficult to cover a large range or dynamically changing bird activity area, and are easily affected by environmental factors, so the bird repelling range and effect are limited. At the same time, birds gradually adapt to a single stimulus source, resulting in a significant decrease in protection efficiency over time. Therefore, the existing technical means are difficult to achieve continuous and effective prevention and control of bird interference in the area of the power transmission line. SUMMARY

[0044] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0045] The application provides a power transmission line bird repelling method applied to a power transmission line bird repelling system. It should be noted that the power transmission line bird repelling system is a system with image processing and multi-modal bird repelling control capabilities, which can realize intelligent identification and risk level assessment of bird activities in the power transmission line area, and can control multiple bird repelling means such as laser, ultrasonic wave, audio playing, and strong light frequency flash according to the assessment results, and dynamically adjust the interference strategy, thereby realizing the functions of the power transmission line bird repelling method described in the application. As shown in the figure, the method can include the following steps: Figure 1

[0046] S101: using a preset visual recognition algorithm to identify bird behavior characteristics and bird activity areas from bird activity videos in the power transmission line area, and determining a threat level corresponding to the bird behavior characteristics.

[0047] The visual recognition algorithm refers to an image processing algorithm for identifying target objects from images or videos, which can specifically include target detection, target tracking, behavior recognition, etc., and can realize detection, behavior analysis, and state recognition of birds in the picture. The bird behavior characteristics refer to the information of the activity state of the birds in the power transmission line area, such as appearance, stay, gathering, hovering, nest building, etc., which is used to judge the potential threat degree to the power transmission line. The bird activity area refers to the actual activity range of the birds in the power transmission line tower, cross arm, insulator string, and surrounding space according to the identification result. The threat level refers to the result of grading and evaluating the risk degree of the power equipment operation caused by the birds after analyzing the bird behavior characteristics and activity area, which is usually divided into low risk, medium risk, and high risk levels.

[0048] During the operation of the power transmission line bird repelling system, the visual recognition algorithm can be deployed in an image processing module or a centralized control server with edge computing capabilities. The front-end camera continuously monitors the power transmission line area and transmits the collected video data to the visual recognition algorithm module for processing in real time. Through the preset target detection model, the power transmission line bird repelling system can detect suspected bird individuals from the video picture, analyze their motion trajectories in a specific area in combination with the time sequence image, and further identify their behavior characteristics, such as hovering and staying, gathering, nest building, etc.

[0049] ​Further, the power line bird repelling system can combine historical behavior data and a set rule base to judge the current identified behavior, and determine the potential risk in combination with the specific area where the birds appear, such as the tower cross arm, insulator and other key parts. For example, when the power line bird repelling system identifies that the birds stay at the tower head for more than a set time length or continuously approach the insulator area for multiple times, it can be determined as medium-high risk behavior. Based on the above identification result, the power line bird repelling system divides the threat level of the current bird activity into low, medium or high risk according to the set risk classification rules, and synchronizes the result to the control unit for strategy scheduling of the bird repelling device.

[0050] In addition, to improve the real-time response and accuracy of the power line bird repelling system, the visual recognition algorithm can also have an online self-learning ability to automatically optimize the parameter configuration of the recognition model according to the bird species in different geographical areas, seasonal migration rules and past behavior data, thereby improving the recognition accuracy and robustness and adaptability of threat level evaluation.

[0051] By using the visual recognition algorithm to identify the behavior characteristics and activity area of birds in the power line bird repelling system, and combining the identification result to evaluate the threat level, not only can the bird disturbance risk be accurately perceived, but also a hierarchical response can be implemented according to the risk level, effectively improving the targeting of the bird repelling means and the resource use efficiency. Since the bird activity has obvious time and space distribution rules and individual differences, by identifying the behavior characteristics and activity range through the algorithm, early warning and dynamic tracking can be realized, avoiding the coverage blind area and response lag problem of the traditional timed bird repelling method. Therefore, using this identification method not only improves the intelligent level of the bird repelling system, but also enhances its practicality and stability in complex power transmission environment.

[0052] S102: If the threat level is low risk, laser emission and ultrasonic interference are performed on the bird activity area.

[0053] Among them, the threat level being low risk means that the behavior characteristics of the birds identified by the visual recognition algorithm indicate that the interference they pose to the power line operation is relatively light, usually manifested as occasional fly-by, short stay or individual dispersed activity, which does not constitute a sustained threat. Laser emission means that the laser device in the power line bird repelling system projects a light beam with a visible wavelength to a specific area to visually interfere with the birds. Ultrasonic interference means using high-frequency sound waves of a certain frequency band to stimulate the birds and make them feel uncomfortable so as to actively move away from the interference area.

[0054] When the visual recognition module in the power line bird repelling system determines that the threat level corresponding to the current bird activity is low risk, the control module will trigger the corresponding low-intensity bird repelling strategy. In this case, the power line bird repelling system control unit first transmits the identified bird activity area coordinates to the laser emitting device. Based on the coordinate information, the device adjusts the emission direction and accurately controls the laser emission angle through the motor driving device, so that the light beam is concentrated on the target area. The emitted laser can be a continuous wave or a pulsed beam, and its wavelength is usually selected from the visible light band sensitive to birds (such as green light and blue light) to enhance the interference effect.

[0055] Subsequently, the power line bird repelling system synchronously controls the ultrasonic wave emitting device, which is equipped with multiple transducer arrays. The corresponding transducer units can be selectively activated according to the orientation of the bird activity area to achieve directional ultrasonic wave emission. The ultrasonic frequency range used is generally above 20 kHz, which is a non-audible frequency range that can effectively stimulate the bird's nervous system while avoiding interference with human staff. The power line bird repelling system can preset the timing strategy for ultrasonic wave emission, such as intermittent emission or frequency modulation, to avoid short-term adaptation of birds.

[0056] To further improve the interference accuracy, laser emission and ultrasonic wave emission can be linked to control, i.e., the emission direction is dynamically adjusted according to the real-time movement trajectory of the birds, so that the laser beam and the sound wave continuously cover the target area. The entire execution process is scheduled by the main control unit of the power line bird repelling system to ensure efficient and energy-saving interference operation, which is suitable for the protection needs in low-risk scenarios.

[0057] By performing laser emission and ultrasonic wave interference in the case of low risk threat level, not only can the birds that occasionally approach or temporarily stay be timely dispersed in a non-contact and non-injuring manner, but also the energy waste and ecological disturbance caused by high-intensity interference methods can be avoided. Laser emission can form strong visual stimulation to guide birds to quickly move away from the activity area, while ultrasonic wave interference provides continuous auditory pressure to intensify the discomfort of birds, effectively enhancing the repelling effect. The synergistic effect of the two methods not only improves the success rate of interference, but also controls the intensity of interference, which helps to delay the formation of bird adaptability. At the same time, through accurate identification and directional control of the target area, the power line bird repelling system can achieve on-demand response and local intervention, thereby reducing resource consumption, improving the overall operation efficiency of the power line bird repelling system, and enhancing the rapid response and flexible disposal capabilities of the power line bird repelling system in low-risk scenarios.

[0058] S103: If the threat level is medium risk, adjust the laser parameters based on the environmental information of the bird activity area, generate a dynamic mesh light spot in the bird activity area, and adjust the playback parameters based on the bird activity state of the bird activity area, then loop the playback of the predator simulation sound to the bird activity area.

[0059] The threat level of medium risk refers to the identified bird behavior showing certain staying tendency or gathering signs, and there is a possibility of nesting or long-term stay, but it does not pose an urgent risk to the line safety. The environmental information of the bird activity area refers to information such as spatial features (such as terrain, vegetation, and tower structure), light conditions, and background interference degree related to the target area. Laser parameters include laser wavelength, power, scanning frequency, deflection angle, and other parameters for controlling the intensity and motion characteristics of the laser beam in space. The dynamic mesh light spot refers to the interlaced or mesh motion light pattern formed by the dynamic deflection of the laser beam in the target area, which is used to enhance the visual stimulation effect. The bird activity state refers to the number of birds, staying time, flight trajectory, and alert response in the target area. The playback parameters include volume, playback interval, sound frequency, and direction control, etc. The audio output control parameters. The predator simulation sound refers to the sound simulated by the bird's natural enemy (such as raptors, snakes, etc.), which is used to stimulate the instinctive escape response of birds.

[0060] When the power transmission line bird repelling system determines that the current bird activity level is medium risk, it means that the bird activity frequency in the power transmission line area is increasing, the staying time is longer, and there is a certain nesting or gathering tendency. The power transmission line bird repelling system will start the medium level response strategy. First, the power transmission line bird repelling system obtains the environmental information of the bird activity area from the visual recognition module, including the spatial scale, the distribution of obstacles, the light reflection characteristics of the area, and other contents, and transmits the information to the laser control unit. Based on the preset parameter adjustment algorithm, the scanning frequency, power output and deflection path of the laser emitter are dynamically adjusted to adapt to the beam propagation characteristics in different scenarios, and the laser beam is controlled by the servo motor system to deflect at high speed along the predetermined trajectory to build an interlaced mesh moving light spot pattern in the target area, thereby forming strong and continuously changing visual interference to the birds.

[0061] Subsequently, the power transmission line bird repelling system will synchronously obtain the activity state information of the birds in the target area, such as the number of individuals staying, whether there is a group gathering, whether there is a nesting behavior, etc. The control unit automatically adjusts the audio playback parameters in combination with the above behavior characteristics, such as increasing the playback volume of the simulation sound, shortening the playback interval time, or switching to more threatening audio materials. The audio playback module can use a directional loudspeaker to adjust the propagation direction of the simulation sound according to the direction of the target area and the wind direction, and realize the timing and cycle playback mechanism through the algorithm of the power transmission line bird repelling system, so that the predator sound has penetration in space and rhythm in time, thereby forming a stable behavior deterrent effect.

[0062] In order to improve the overall interference effect, the power transmission line bird repelling system can also link the timing control of laser and audio, trigger the audio and light linkage mode when the bird group gathers, and gradually reduce the interference intensity after the activity tends to disperse, realize the flexible regulation of the bird repelling strategy, and avoid overstimulation to cause the enhancement of bird adaptability.

[0063] By adjusting the laser parameters according to the environmental information of the bird activity area and generating a dynamic mesh light spot, the effectiveness of laser interference under different space conditions can be improved, making the laser stimulation have the advantages of high visual intensity, strong dynamic change and wide coverage, enhancing the insecurity of birds and prompting them to actively avoid; At the same time, according to the bird activity state, the playing parameters of the enemy simulation sound are adjusted dynamically, so that the sound interference has high matching and behavior driving, and the psychological deterrent effect on the target birds is strengthened. The coordinated intervention of laser and audio not only improves the adaptability and effectiveness of the bird repelling response in the medium risk scene, but also avoids excessive energy consumption and unnecessary impact on the ecological environment, so as to realize the differentiated and accurate response of the power line bird repelling system under different risk levels, and has higher intelligence, economy and continuous driving effect.

[0064] S104: If the threat level is high risk, the laser scanning and ultrasonic interference are jointly started at the highest power, and the strong light stroboscopic is started to form a three-dimensional interference field in the bird activity area.

[0065] Among them, the threat level is high risk, which means that the bird has shown strong interference behavior in the power line area, such as staying for a long time, gathering in groups, repeatedly returning or nesting, etc., and has posed a serious threat to the safe operation of the line. The strong light stroboscopic refers to the periodic and rapid flashing of strong light by using high-brightness lamps to form a strong light stimulus. The three-dimensional interference field refers to a multi-source, multi-dimensional stimulation area formed by the joint deployment of laser, ultrasonic wave and stroboscopic light in space, which has the ability of all-round, multi-modal and high-intensity interference, and is used to suppress high-risk bird behavior.

[0066] When the power line bird repelling system identifies that there is high-risk bird behavior in the target area, the control module immediately starts the high-level response strategy. Under this strategy, the laser control unit receives the accurate coordinate information from the identification module and calls the highest power configuration of the laser equipment. By driving the high-speed rotating or mirror assembly, the laser beam performs high-frequency, multi-angle and full-area scanning in the bird activity area, forming a high-brightness laser light belt moving rapidly, which causes strong stimulation to the bird's visual nervous system, thereby breaking its continuous stay or nesting behavior.

[0067] Then, the power line bird repelling system synchronously starts the ultrasonic interference module and switches to the high-power emission mode. The transducer array outputs high-intensity ultrasonic signals of multiple frequency bands, forming a sound wave field with wide coverage and strong penetration, and can use frequency alternation, phase modulation and other technologies to increase the sound wave variability and interference depth, preventing the birds from adapting in the short term. This module can also be linked with the visual identification result for directional enhancement to realize sound wave focused attack on key areas.

[0068] Further, the power transmission line bird repelling system control unit starts the strong light stroboscopic device, which is arranged above the cross arm of the tower or the area where birds often stop, and uses high-brightness LED array lamps to periodically flash at a frequency of 20 Hz to 50 Hz, simulating lightning or predator flash warning effect. The stroboscopic light beam forms a very high visual stimulation intensity, and can be focused in a region by means of an optical lens, further enhancing the fear psychology of birds.

[0069] Finally, the three interference means operate in coordination to construct a three-dimensional interference field in space covering visual, auditory and psychological stimulation. The power transmission line bird repelling system can set the duration of interference, the flashing rhythm and the sound wave rotation mode, realize real-time adjustment of the intervention strategy according to the bird reaction, and ensure that the repelling effect is maximized and there is no interference blind area.

[0070] By jointly starting the laser scanning and ultrasonic interference at the highest power when a high-risk threat is identified, and supplemented by strong light stroboscopic, a high-intensity, all-around, dynamically changing three-dimensional interference field can be quickly constructed, forming a multi-channel compression effect on the bird's senses, thereby effectively interrupting the bird's nesting, resting or gathering behavior. This method has stronger intervention efficiency and lower adaptation risk than single means, can disperse high-density bird flocks in the shortest time, reduce the probability of electrical faults such as short circuit and trip caused by bird damage, and improve the operation safety and reliability of the power transmission line. At the same time, through reasonable linkage and regional focusing control, energy consumption can also be controlled while ensuring the effect, reflecting the response capability, energy saving and intelligent level of the power transmission line bird repelling system in high-risk scenarios.

[0071] In the above embodiment, by introducing a visual recognition algorithm, the behavior characteristics and activity area of birds in the power transmission line area can be accurately identified, and the threat level can be intelligently evaluated combined with the behavior characteristics, realizing the graded management of bird interference risk. For different risk levels, different multi-modal bird repelling means are used. For low-risk areas, non-contact means such as laser and ultrasonic are used for gentle interference; for medium-risk areas, dynamic light spots are formed by dynamically adjusting the laser parameters combined with environmental information, and parameter-optimized predator simulation sound is played synchronously to realize the composite stimulation of vision and hearing; and in high-risk situations, a three-dimensional interference field is constructed by jointly starting the laser, ultrasonic and strong light stroboscopic at maximum power, to improve the intervention intensity and coverage. This method improves the bird repelling efficiency while effectively delaying the adaptation process of birds to the bird repelling means, enhances the adaptability of the bird repelling system to complex environments and dynamic bird activities, and significantly improves the sustainability and effectiveness of bird damage prevention and control in the power transmission line area.

[0072] In one embodiment, the step of determining the threat level corresponding to the bird behavior characteristics comprises:

[0073] When the bird behavior feature belongs to the flying behavior, the threat level corresponding to the bird behavior feature is determined as low risk;

[0074] When the bird behavior feature belongs to the wandering behavior, the threat level corresponding to the bird behavior feature is determined as medium risk;

[0075] When the bird behavior feature belongs to the staying behavior, the threat level corresponding to the bird behavior feature is determined as high risk.

[0076] Among them, the flying behavior refers to the bird passing through the area above or near the power transmission line quickly without stopping or slowing down significantly, usually with short duration and light interference. The wandering behavior refers to the bird circling, repeatedly approaching or staying for a short time in the low altitude of the power transmission line area, showing the detection behavior to the surrounding environment, and having a certain degree of interference potential. The staying behavior refers to the bird landing, inhabiting or even nesting on the power transmission line equipment (such as iron tower, cross arm, insulator string, etc.), which has long-term and high-risk attributes, and is the main reason for causing trip-out, short circuit and other faults.

[0077] The power transmission line bird repelling system collects bird activity video data in the monitoring area in real time through image acquisition devices deployed around the tower or line. The visual recognition module in the power transmission line bird repelling system analyzes the video data, extracts the flight trajectory, speed, stay time, activity range and other behavior parameters of the bird, and performs feature comparison and behavior classification based on the pre-set behavior model.

[0078] When the bird is identified to pass through the monitoring area in a straight line or parabolic trajectory quickly without slowing down, circling or staying on any equipment surface, the power transmission line bird repelling system judges its behavior as flying behavior and marks it as low risk level to avoid overreaction to non-interference flight.

[0079] When the bird is identified to circle repeatedly, glide in low altitude, approach and leave, or even stay for a short time but fly away quickly in the line area, the power transmission line bird repelling system judges it as wandering behavior. Such behavior usually means that the bird is evaluating whether to land or nest in the area, so the system marks the behavior as medium risk level and prepares to trigger moderate intensity intervention measures.

[0080] Further, when the power transmission line bird repelling system identifies that the bird stays on the surface of the tower cross arm, insulator, fitting and other equipment for a long time, or detects repeated behaviors such as nesting, the power transmission line bird repelling system judges it as staying behavior. At this time, the power transmission line bird repelling system marks the behavior feature as high risk level and enters the high level protection response stage to maximize the safety of the line.

[0081] By determining the corresponding threat level according to the behavior type of birds and matching and executing different levels of interference strategies in the power transmission line bird repelling system, the response accuracy and resource utilization efficiency of the power transmission line bird repelling system can be improved while ensuring the safety of the line. Specifically, the flying behavior is determined as low risk, which avoids overreaction to harmless behavior and saves device energy consumption; the wandering behavior is identified as medium risk, which helps to discover potential nesting risks early and intervene timely; the residence behavior is identified as high risk, which enables the power transmission line bird repelling system to mobilize high-intensity intervention means in time to effectively prevent equipment damage and power supply failure. The identification and classification mechanism realizes dynamic prevention and control strategy adjustment through intelligent behavior analysis, improving the intelligent level and the persistence of the protection effect of the power transmission line bird repelling system.

[0082] In one embodiment, the steps of laser emission and ultrasonic wave interference on the bird activity area include:

[0083] Laser emission on the bird activity area for a preset number of times, and ultrasonic wave interference on the bird activity area for a preset time.

[0084] When the power transmission line bird repelling system detects the bird activity area and identifies the behavior level as low risk or medium risk, the power transmission line bird repelling system control module starts the laser bird repelling device according to the set strategy. The device irradiates the bird activity area with directional laser multiple times according to the control command. Specifically, the power transmission line bird repelling system control module can set a laser emission counter, which triggers laser emission every set time interval within the bird repelling period until it automatically stops after reaching the preset upper limit of the number of times. The emission direction and angle of the laser can be adjusted by a pan-tilt or a stepper motor to ensure coverage of the entire identified bird activity area and improve the interference coverage.

[0085] Subsequently, during or after the execution of laser intervention, the power transmission line bird repelling system further activates the ultrasonic wave interference module. The module controls the duration of ultrasonic wave playing through a preset time parameter, which is usually configured to vary from several seconds to tens of seconds to adapt to the auditory sensitivity of different bird species. To avoid adaptive response of birds, the power transmission line bird repelling system can randomly switch different frequency bands of ultrasonic wave signals within a preset time range to improve the uncertainty and irritability of acoustic interference. This stage can be executed in parallel or alternately with laser emission to build a multi-modal bird repelling scene.

[0086] To improve the accuracy of execution, the power transmission line bird repelling system can dynamically adjust the laser emission position and ultrasonic wave radiation angle in combination with real-time identification results to ensure that the interference action covers the actual activity area and reduces invalid operations.

[0087] By performing laser emission within a preset number of times and implementing ultrasonic interference within a preset time, not only can the execution frequency and time of intervention behavior be effectively limited to avoid excessive harm to birds or cause ecological disturbance, but also the energy efficiency of the power transmission line bird repelling system and the service life of the equipment can be considered. Laser emission makes birds feel strong discomfort through visual stimulation, forcing them to leave the area for a short time; and ultrasonic interference further strengthens the driving effect through the auditory channel, building a multi-sensory collaborative bird repelling mechanism. This combined strategy helps to achieve efficient bird repelling without the need for continuous high-intensity intervention, improving system stability and sustainable operation capability.

[0088] In one embodiment, the step of implementing ultrasonic interference on the bird activity area within a preset time includes:

[0089] Determining the position of the bird in the bird activity area, and setting the ultrasonic frequency range, ultrasonic pulse interval, and ultrasonic angle according to the position of the bird;

[0090] Based on the ultrasonic angle and the preset time, ultrasonic waves are emitted to the bird activity area within the ultrasonic frequency range in a random frequency hopping mode combined with the ultrasonic pulse interval.

[0091] Wherein, the bird position refers to the specific coordinate information of the bird in two-dimensional or three-dimensional space in the power transmission line area determined by image recognition algorithm or infrared ranging device, which is used to guide the directional intervention of the bird repelling device. The ultrasonic frequency range refers to the high-frequency sound frequency band interval for driving birds set according to the bird species, physiological structure, and environmental conditions, usually above 15 kHz. The ultrasonic pulse interval refers to the time interval parameter for controlling the emission of ultrasonic waves, which is used to control the pulse emission rhythm to improve the interference intensity. The ultrasonic angle refers to the emission direction or divergence angle of the ultrasonic emitter relative to the position of the bird. The random frequency hopping mode refers to the discontinuous and random switching of the emission frequency within the set frequency range to prevent birds from adapting to the fixed frequency.

[0092] When the power transmission line bird repelling system identifies that there are birds in the power transmission line area, the visual recognition unit or radar module will accurately calculate the spatial position of the birds, including horizontal angle, vertical angle, and distance information. The power transmission line bird repelling system control unit calculates the optimal interference direction in real time based on this position information, and sets the emission angle of the ultrasonic emission device to ensure that the interference signal can accurately cover the target bird area.

[0093] Then, the power transmission line bird repelling system selects a suitable ultrasonic frequency range according to the distance and species characteristics of the birds. For example, for birds with larger body size and higher vigilance, a frequency range of 20-35 kHz can be selected to enhance their discomfort; while for small birds, a higher frequency band can be selected. At the same time, the power transmission line bird repelling system will also set the pulse interval of the ultrasonic wave. The specific interval time can be dynamically adjusted in combination with the bird's residence time, behavior activity and environmental noise level, generally controlled between tens of milliseconds to hundreds of milliseconds, to improve the burstiness of the interference.

[0094] Subsequently, after completing the above parameter setting, the power transmission line bird repelling system starts the ultrasonic wave emitting device. Under the instruction of the control unit, the device continuously switches the emission frequency within the frequency range according to the set emission angle and time window, and intermittently emits in combination with the set pulse interval. Random frequency hopping makes the frequency distribution of ultrasonic interference signals change irregularly, effectively avoiding the risk of birds adapting to fixed frequency sound waves, and improving the overall driving efficiency.

[0095] By combining the actual position of birds in the power transmission line area, accurately setting the frequency range, emission angle and pulse interval of the ultrasonic wave, the spatial directivity and frequency diversity of the ultrasonic interference can be significantly improved. Using the random frequency hopping emission mode can break the disadvantage of traditional single-frequency interference being easily adapted by birds, enhance the unpredictability of the stimulus, and effectively prolong the duration and intensity of the interference effect. By combining the above methods, not only can the intervention coverage accuracy and interference diversity of the bird repelling system be improved, but also the energy consumption and false emission rate of the power transmission line bird repelling system can be reduced, thereby achieving a more efficient, environmentally friendly and intelligent power transmission line bird interference control goal.

[0096] In one embodiment, the laser parameters include laser combination, laser scanning angle and laser scanning speed;

[0097] After adjusting the laser parameters according to the environmental information of the bird activity area, the step of generating a dynamic mesh light spot in the bird activity area includes:

[0098] The environmental information of the bird activity area includes meteorological conditions, light intensity, obstacle distribution information and bird position;

[0099] The laser combination suitable for the meteorological conditions and light intensity is selected, and the laser scanning angle and laser scanning speed are adjusted according to the obstacle distribution information and bird position;

[0100] After generating a laser beam corresponding to the laser combination, the laser beam is controlled in the bird activity area according to the laser scanning angle and laser scanning speed to form a dynamic mesh light spot in a non-linear dynamic scanning path.

[0101] The environmental information refers to external condition parameters that affect the laser emission path, interference effect, and spot imaging quality, and specifically includes meteorological conditions (such as wind speed, rain, snow, humidity, etc.), light intensity (such as sunlight intensity, background brightness, etc.), obstacle distribution information (such as the distribution position of shielding objects such as power transmission tower structures, cables, trees, etc.), and bird position (i.e., the coordinate point or activity area boundary range of birds in space); the laser combination refers to a laser configuration set of multiple wavelengths, powers, or emission modes in the adjustable laser interference system to adapt to different external conditions. The laser scanning angle is the deflection range of the laser scanning path in the horizontal and vertical directions. The laser scanning rotation speed refers to the speed of completing unit angle change of the laser beam within the set angle range. The dynamic mesh light spot refers to the interlaced and moving light mesh structure pattern formed in the target area by the continuous movement of the laser beam according to a nonlinear trajectory.

[0102] The power transmission line bird repelling system first collects the environmental information of the bird activity area of the power transmission line through the environmental monitoring module. The meteorological conditions can be obtained by local meteorological sensors or by accessing meteorological cloud platform data, the light intensity is measured in real time by a photosensitive sensor, the obstacle distribution information is obtained by modeling through a LiDAR or a stereo camera system, and the bird position is calibrated by an image recognition or thermal imaging module.

[0103] Next, the power transmission line bird repelling system control module selects a laser combination that adapts to the current meteorological conditions and light intensity based on the above collected environmental information. For example, in the noon period with strong light, a blue-green laser with short wavelength and high brightness can be selected; while in low visibility such as foggy weather or at night, an infrared laser combination with longer wavelength and strong penetration is preferred. At the same time, the power transmission line bird repelling system adjusts the scanning angle of the laser according to the spatial distribution of the obstacles and the specific position of the birds, avoids the shielding area, and dynamically sets the laser scanning rotation speed according to the distribution density of the target birds, to ensure that the light spot is fully covered and the interference frequency is moderate.

[0104] Subsequently, the power transmission line bird repelling system controls the laser device to generate corresponding laser beams, and combines the set scanning angle and scanning rotation speed to control the laser beams to move and scan quickly according to a nonlinear trajectory (such as a Lissajous curve or a spiral trajectory), so that a dynamic mesh light spot that moves and irregularly intersects is finally formed in the bird activity area. The light spot can continuously change position and shape in space, create a visual disturbance effect, and achieve the purpose of continuously interfering with the neural perception system of birds.

[0105] By dynamically adjusting the laser parameters according to the environmental information of the bird activity area, the adaptability of the laser interference effect to different external environments can be enhanced, and the driving failure caused by fixed parameters can be avoided; by combining the obstacle distribution and the bird position to set the scanning angle and the rotating speed, the light spot coverage rate can be effectively improved and the laser blind area can be avoided, thereby improving the bird driving accuracy; further, the dynamic mesh light spot generated by the nonlinear trajectory can continuously create visual disturbance, break the adaptability of the birds to the static light source, significantly prolong the interference time and reduce the willingness of the birds to stay in the power transmission line area. Therefore, the method can still maintain efficient, accurate and sustainable bird driving effect in complex environments, and significantly improves the operation safety of the power transmission line and the intelligent level of bird damage prevention and control.

[0106] In one embodiment, after adjusting the playing parameters according to the bird activity state of the bird activity area, the step of playing the predator simulation sound to the bird activity area in a loop includes:

[0107] The bird activity state of the bird activity area is determined, and the bird activity state includes the bird position, the bird flight speed and the bird calling frequency;

[0108] Based on the bird position, the bird flight speed and the bird calling frequency, the playing parameters are adjusted by using the Doppler effect, and the predator simulation sound is played to the bird activity area in a loop.

[0109] The power transmission line bird driving system first acquires the flight trajectory of the birds in the air in real time through the high-definition camera, laser range finder or radar module deployed on the power transmission line tower, and determines the bird position by using image analysis algorithm or point cloud tracking technology. By comparing consecutive frames or analyzing radar echoes, the power transmission line bird driving system further calculates the flight speed of the birds and extracts the speed vector information. At the same time, the calling sound waves emitted by the birds are collected by the sound pickup device, and the main frequency and spectral characteristics are extracted by fast Fourier transform (FFT), and then the current calling frequency of the birds is determined.

[0110] Subsequently, the bird position, flight speed and calling frequency are input into the acoustic simulation module by the control unit of the power transmission line bird driving system. In this module, the Doppler effect acoustic model is used to reconstruct the parameters of the predator simulation sound. Taking the MATLAB simulation platform as an example, the power transmission line bird driving system calculates the frequency offset when approaching or moving away in real time according to the approaching speed of the birds and the basic frequency of the simulation sound, and adjusts the output frequency of the simulation sound in the playing module, so that the audio simulates the approaching state of the predator in the space of the birds, such as the screaming of the hawk falcon when it quickly dives, so as to make the birds feel the imminent crisis.

[0111] After the playback parameter setting is completed, the power line bird repelling system control simulation audio player plays the modulated predator simulation sound in the bird activity area. During the playback process, if the bird speed or position changes significantly, the power line bird repelling system can recalculate the playback parameters to achieve dynamic adjustment, ensuring that the simulation sound always fits the bird perception characteristics. The playback process can combine directional loudspeaker array control to control the sound projection direction and combine environmental information control to control the volume level, ensuring that the sound coverage does not leak to irrelevant areas and does not interfere with other equipment.

[0112] By determining the position, flight speed and calling frequency in the bird activity state, the power line bird repelling system can accurately capture the behavior dynamics of birds in the power line airspace, thereby constructing an accurate sound source positioning model; based on the Doppler effect adjustment of the playback parameters, the simulation sound frequency can be changed in real time according to the bird movement trend, making the playback effect closer to the auditory characteristics of the predator approaching in nature. Compared with the traditional fixed frequency playback method, this method can significantly enhance the behavior interference intensity of the simulation sound on birds, improve their perception sensitivity to the threat of predators, and prompt them to quickly move away from the power line area. Further, the cyclic playback of the dynamically frequency-modulated simulation sound can also effectively prolong the interference time, slow down the formation of adaptive memory of birds, and enhance the long-term bird repelling effect of the system. Therefore, the present embodiment not only realizes dynamic, real-time and directional acoustic bird repelling, but also has high adaptability, high dispersion rate and intelligent feedback capability, significantly improving the bird damage prevention and control level and operation reliability of the power line.

[0113] In one embodiment, the step of turning on the strong light stroboscopic light includes:

[0114] The flashing parameters are set according to the environmental information, and the strong light stroboscopic light is turned on according to the flashing parameters. The flashing parameters include flashing frequency, light intensity, flashing duration and spectral combination mode.

[0115] The flashing parameters are control parameter sets used to drive the light-emitting behavior of the strong light stroboscopic light device, and at least include flashing frequency (number of flashes per unit time), light intensity (light source brightness or power), flashing duration (single flashing time) and spectral combination mode (combination scheme of different wavelengths or colors of light).

[0116] During the operation of the power line bird repelling system, the environmental information of the target area is first collected in real time by the environmental perception module deployed on the top or middle of the power line tower. The module can include a brightness sensor, a weather monitor, an infrared thermal imager, etc., which are used to obtain light intensity, weather conditions and bird activity information within the field of view, respectively. The obtained data will be transmitted to the control center for subsequent bird repelling control logic judgment.

[0117] Next, the control unit of the power transmission line bird deterrence system automatically sets appropriate flashing parameters based on environmental information. Specifically, when the ambient light intensity is weak (such as at dusk, on cloudy days, or in dense fog), the system automatically increases the light intensity parameter to enhance the visibility of the flashes. If there is rain or strong wind, the flashing frequency is appropriately increased and the flashing duration is shortened to enhance instantaneous visual stimulation and avoid increasing the equipment load due to continuous strong light. In addition, if the detected bird activity area is in an open area, a high-penetration cool color spectrum combination mode, such as alternating flashes of blue and white light, can be selected to enhance the interference effect on the birds' visual system. If there are structural obstructions in the activity area, the system switches to a combination of red and white light to enhance local reflection interference.

[0118] Then, the power transmission line bird deterrence system controller activates the high-intensity strobe module based on the set flashing parameters. This module can use an LED matrix or laser strobe array as its light source, emitting light intermittently at a set frequency under the control of the drive circuit, thus creating a frequently changing, bright stimulus source within the bird activity area. The strobe angle and range can be adjusted via a motorized pan-tilt head or motorized optical lens assembly to ensure that the beam accurately covers the target area, especially in areas where birds linger for long periods and are irregularly distributed, where dynamic angle scanning can achieve more comprehensive visual interference.

[0119] During the strobe process, the transmission line bird deterrence system can also monitor in real time whether the birds have been successfully driven away. If the expected effect is not achieved, the transmission line bird deterrence system can adjust the frequency to jump upward or increase the light intensity to enhance the deterrence capability. After confirming the effect, the strobe unit is turned off and enters a low-power standby mode.

[0120] By setting flicker parameters based on environmental information, the behavior of strong light flashing can be made more consistent with current lighting and weather conditions, thereby enhancing the stimulation efficiency on birds' visual systems. Furthermore, by activating strong light flashing according to these parameters, a rhythmic and spectrally diverse strong light interference effect is created within the bird activity area along power transmission lines. This effectively disrupts birds' visual stability mechanisms, causing them to flee. Since birds are extremely sensitive to strong light and flashing signals, especially in low-light or low-visibility environments, flashing is more likely to cause flight path deviations or landing interruptions, thus increasing the success rate of bird deterrence. Therefore, this method is not only flexibly adaptable to different environmental conditions but also dynamically adjusts flicker characteristics to cope with complex bird behavior patterns. It possesses high adaptability, high interference, and strong deterrent effect, helping to ensure the safe operation of power transmission lines and extend equipment lifespan.
