Problems solved by technology

However, the efficiency of manual inspection is low, and the nesting activities of birds on transmission line towers cannot be found in time. Moreover, manual inspection in remote areas is time-consuming and laborious, and it is impossible to release observation information and give early warning in time
The above low-efficiency manual inspection method cannot effectively monitor the bird activities in the transmission line channel, resulting in many bird-related faults in the power system

Embodiment Construction

[0026] The specific embodiment of the present invention is shown in the figure.

[0027] Such as figure 1 As shown, a radar-based bird flock monitoring method in this embodiment includes:

[0028] (1) Turn on the radar system, the frequency synthesizer generates a chirp signal under the action of the reference signal source, and generates a chirp signal in the required frequency band through quadrature demodulation and frequency multiplication 2, and the chirp signal passes through multiple stages all the way After being amplified, it is emitted by the transmitting antenna, and the other is coupled to the mixer as a local oscillator signal.

[0029] (2) High-frequency electromagnetic waves will be reflected back to the receiving antenna after encountering the target, and output to the mixer after being amplified by low noise to mix the beat signal, then filtered and amplified by low-pass characteristics, and then sent to digital signal processing 5. Under the influence of th...

Abstract

A radar-based bird flock monitoring method comprises the steps of moving target scanning by means of a radar, moving target identification, video monitoring and shooting, terminal display of video images and the like. The radar-based bird flock monitoring method completes the monitoring of bird flocks, adopts a series of processing such as background differencing, noise suppression, target information extraction and coordinate fusion on bird flock identification, is precise in target locking and is convenient for intuitive reading. Through setting the full-phase-coherence continuous wave system radar, the radar-based bird flock monitoring method can be used for discovering, monitoring, tracking and measuring the low-altitude bird flock targets, and can transmit and report moving information of the targets according to a specified format to relevant departments, so as to grasp real-time relevant information of the moving targets in a monitored region at any time.

Description

technical field [0001] The invention relates to a radar-based bird flock monitoring method, which belongs to the technical field of power line bird repelling. Background technique [0002] At present, the power grid company mainly monitors the activities of transmission line towers and surrounding birds through manual inspection. However, the efficiency of manual inspection is low, and bird nesting activities on transmission line towers cannot be found in time. Moreover, manual inspection in remote areas is time-consuming and laborious, and it is impossible to release observation information and give early warning in time. The above low-efficiency manual inspection method cannot effectively monitor the bird activities in the transmission line channel, resulting in many bird-related faults in the power system. [0003] Therefore, in order to effectively monitor the bird activities in the transmission line corridor, it is necessary to invent a radar-based bird monitoring meth...
