Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In view of the demand for bird repelling on high-voltage transmission line towers, optical camera imaging is currently used for detection, but optical sensors are expensive and easily affected by the external environment (such as light, temperature, etc.), resulting in a decline in detection effect. In contrast, millimeter-wave radar is small in size, easy to install, and has high spatial resolution. It has a strong ability to penetrate smoke, fog, dust, rain and snow, and is less susceptible to interference. In terms of environmental robustness, it is much better than other sensors, has better imaging capabilities, can work around the clock, and has the advantages of high distance accuracy, high angular resolution and low false alarm rate. The scene of bird repelling bird has unique advantages. Bird repellent can use sound waves or li...

Abstract

The invention relates to a millimeter-wave-radar-based high-voltage transmission line tower bird detecting and repelling system and method. The system comprises a millimeter-wave radar detection module which is used for detecting whether there is a bird entering a detection region or not and detecting the current distance, and transmits collected data to a central control module. The central control module sends an instruction to control a sound wave warning module and a light warning module to be turned on, and the bird entering the monitoring area is expelled. The bird detecting and repelling method comprises the steps of sampling, distance estimation, speed estimation, distance-Doppler thermodynamic diagram acquisition, CFAR detection in the distance direction and the Doppler direction respectively, target detailed distance and Doppler information acquisition and output to the central control module. The central control module removes noise and suppresses interference and then judges whether the bird invades or not. The bird repelling manner is friendly, the system can work around the clock, installation is convenient, and environmental adaptability is high.

Description

technical field [0001] The invention belongs to the field of millimeter-wave radar, and in particular relates to a system and method for detecting and repelling birds of high-voltage transmission line towers and towers based on millimeter-wave radar. Background technique [0002] Long-distance high-voltage power transmission has been widely used, and the towers of power system transmission lines are mostly erected in open places. Due to the firmness and stability of the tower, birds like to build nests on the tower during the breeding season to build a place for the birds to move about. However, it uses tree branches, dead vines, waste cotton threads, and even iron wires to build its nests. The whereabouts of the materials may short-circuit a few pieces of porcelain bottles, causing the line to trip; Feces will pollute the porcelain bottle, reduce the insulation strength of the porcelain bottle string, and cause the line to trip. Especially in recent years, the improvement...
