[0028] In one embodiment of the present invention, the fixed housing 5 is an elliptical structure to match the moving track of the rotating component.

[0029] In one embodiment of the present invention, the function of the rotating component is to drive the sound wave bird-repelling component to rotate around the fixed base plate 4, so that the sound waves are not fixed in one place and spread. In this way, the fluidity of the sound waves can be achieved, misleading birds into thinking that the sound waves are interfered by real natural enemy animals, thereby preventing birds from adapting.

[0033] In one embodiment of the present invention, the sonic bird-repelling assembly includes an ultrasonic generator and an infrasonic generator.

[0034] In one embodiment of the present invention, reinforcing ribs are further provided at the connection between the fixed base plate 4 and the support column 2 .

[0035] In one embodiment of the present invention, the control module specifically comprises an image acquisition module, a bird recognition module, a bird motion analysis module, a data storage module, a timing control module, and a multi-strategy bird repellent execution module. Each module interacts with the main controller (STM32H743) via the CAN bus to achieve real-time data exchange. The system workflow is as follows: Image acquisition: The gimbal equipped with a dual-light camera (visible light + thermal imaging) captures a 1080P image every 500ms. ROI partitioning (covering a sector-shaped area with a radius of 50m) reduces the computational load.

[0036] Object Recognition: The YOLOv8s model was used for bird detection (mAP@0.5 reached 89.7%), combined with ResNet-50 transfer learning to achieve classification of 23 common bird species (92.3% accuracy).

[0037] Motion analysis: Calculate bird flight speed (vbird) based on the optical flow method, and predict trajectory using Kalman filtering (prediction error < 0.3m).

[0038] Strategy decision-making: The main controller integrates bird species, numbers, flight parameters and historical data to dynamically select the bird-repelling mode.

[0039] Execution feedback: The bird-repelling system uses a multi-modal combination of ultrasound (20-25kHz), laser (wavelength 980nm), and sound waves (55-85dB). The bird-repelling effect is fed back in real time through a pressure sensor (range 0-50kPa).

[0040] Furthermore, the Bird Activity Index (BAI) is defined as: ; Ni, the number of birds of type i (counted by YOLO detection box); vi Average flight speed (m / s); Ai activity area (m²); αi species sensitivity coefficient (sparrow α=0.8, eagle α=1.5); when BAI>0.7, a level one alarm is triggered and full-band expulsion is initiated.

[0041] Based on the bird's auditory sensitivity curve, a frequency response function is established: H(f): Response function of the basilar membrane of the bird cochlea (peak at 3.5kHz for sparrows); S(f): ambient noise spectrum (obtained by FFT analysis); D(f) is the distance attenuation factor (D(f) = e − 0.01r, where r is the distance in meters). Experiments show that the most effective ultrasonic frequency for repelling crows is 23.5 kHz.

[0042] Furthermore, the composite expulsion energy field intensity is defined as follows: ; Laser energy: Elaser = Pavg⋅t (P = 1.5 W, t = 500 ms); Sound wave energy: Eacoustic=21ρvω2A2 (ρ=1.225kg / m³, v=340m / s); Coefficient adjustment: k1=0.6 (sunny day), k2=0.4 (rainy day); when Etotal>12J / m2, the expulsion success rate can reach 91%.

[0043] Further, dynamic dry path removal algorithm: Use the improved A* algorithm to achieve optimal gimbal steering: ; dpath: remaining path length (m); θrot: gimbal rotation angle (°); Eremain: remaining battery power (%); Weight coefficients: w1=0.5, w2=0.3, w3=0.2; this algorithm reduces the gimbal steering delay to 120ms and reduces energy consumption by 27%.
