A farm bird repellent device according to claim 8, characterized in that: The image data analysis module is used to collect sky image data of the current farm through an image collection device (21), and to obtain whether there are bird feature points in the sky image data by analyzing the collected sky image data. If there are bird feature points in the obtained sky image data, an expulsion instruction is generated and sent to the processing module; The function of the processing module is to analyze the farm area where the bird feature points may exist based on the bird feature points existing in the sky image data, and to control the corresponding lighting device body (22) and the sound wave bird-repelling device (11) to perform output operations to complete the bird-repelling operation.

10. The farm bird repellent device according to claim 1, characterized in that: The function of the control module is to control the corresponding sound wave bird-repelling device (11) to perform output operation according to the acquired farm area parameter data where the bird feature points may exist, and the bird-repelling operation is completed by the infrasound waves generated by the output of the sound wave bird-repelling device (11), wherein the frequency of the infrasound waves is 10 Hz-20 Hz; The control module also functions to control the illumination device body (22) to continuously flash and output operations according to the acquired farm area parameter data where the bird feature points may exist, and to complete the bird-repelling operation by outputting different wavelengths and frequencies through the illumination device body (22), wherein the wavelength adopts a blue light range of 400-500nm, and the flashing frequency is one flash per 0.5S.
