Device and method for automatically detecting field bird whistling

Abstract

The invention belongs to the technical field of bird chirp detection and information and particularly relates to a field bird chirp automatic detection device and method, and the device is a rigid sphere structure with a pickup window in the middle. The device specifically comprises an upper semicircular shell (1), a lower semicircular shell (2), a circuit bin (3) and a pickup sensor array (6), wherein the upper semicircular shell (1) and the lower semicircular shell (2) are vertically arranged, the upper semicircular shell (1) and the lower semicircular shell (2) are separated from each other, and an air dielectric layer is arranged between the upper semicircular shell (1) and the lower semicircular shell (2) to serve as a pickup window (4); the circuit bin (3) and the pickup sensor array (6) are arranged in the lower semicircular shell (2), the pickup sensor array (6) is arranged on the outer circumference of the top surface of the lower semicircular shell (2), and the sealed circuit bin (3) is arranged below the pickup sensor array (6).

Description

technical field [0001] The invention belongs to the field of bird song detection and information technology, and in particular relates to an automatic detection device and method for wild bird song. Background technique [0002] Islands are important habitats for birds, and they are also important places for the protection and utilization of the ecological environment of birds. For the domestic bird monitoring network, a large number of bird surveys and monitoring work have been carried out, mainly focusing on the research on the species, quantity and distribution of terrestrial birds in a region, and good results have been achieved. In order to promote bird monitoring, in recent years, demonstration monitoring of biodiversity (birds) has been carried out, and through pilot research, the establishment of a biodiversity monitoring network has been explored. At present, the research on island and coastal wetland birds is relatively weak, and only limited research has been car...

AI Technical Summary

Problems solved by technology

[0003] Island wetlands are important places for birds to inhabit, migrate, and reproduce. They are of great significance to bird research. Bird surveys and data analysis on islands and other places often require a lot of time, manpower, and material resources, with high costs and low efficiency. Low

In addition, for island wetlands, there are still problems such as special geographical environment, inconvenient transportation, harsh and changeable climate, and complex background noise. Most of the existing acoustic sensors are single-unit devices, and the formed wireless sensor network is vulnerable The impact of noise such as ocean waves and sea breeze is not conducive to obtaining bird songs with high signal-to-noise ratio, and it is difficult to apply to the needs of intelligent and online monitoring of bird songs in the island environment

At the same time, the collection and transmission of useless noise signals also waste a lot of transmission and storage resources

[0004] In addition, the existing bird song detection device cannot timely and accurately obtain the effective bird song in the area where the monitoring device is located, and cannot remove a large amount of environmental noise when there is no song, which increases power consumption and reduces the monitoring of the song Efficiency, unable to adapt to remote automatic monitoring of bird ecology under long-term and unattended conditions in complex wild environments
