System and method for monitoring intensity and distribution of birdsongs in wild

Abstract

The invention provides a system for monitoring the intensity and the distribution of birdsongs in the wild. The system comprises a standing wave pickup microphone array, a control processing unit, a wireless data transmission unit and a display and control unit which are sequentially connected in order; the standing wave pickup microphone array is connected with the control processing unit by using a cable; the control processing unit is arranged in a waterproof housing; the standing wave pickup microphone array and the control processing unit are arranged at a monitoring node in the wild, a plurality of birdsong signals in the wild are collected and processed, and an optimal total birdsong signal is obtained; and the optimal total birdsong signal is transmitted to the display and controlunit through the wireless data transmission unit. According to the system provided by the present invention, unattended automatic remote monitoring of the birdsongs is realized, a rapid response of bird behavioral monitoring is solved, the technical bottleneck of remote automatic ecological monitoring of birds is broken through, and the system can be applied to bird and ecological environment monitoring in special environments such as islands, wetlands and the like.

Description

technical field [0001] The invention relates to the technical field of ornithology, bird song monitoring and information, in particular to a system and method for monitoring the intensity and distribution of bird song in the wild. 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. Developed countries such as the United States and the United Kingdom have established national-scale bird monitoring networks and achieved good results. my country has also carried out a large number of bird surveys and monitoring work, mainly focusing on the research on the species, quantity and distribution of terrestrial birds in an area. In order to promote the monitoring of birds in my country, in 2011, the Nanjing Institute of Environmental Science of the Ministry of Environmental Protection organized a demonstration monitoring of biodiversity (birds), and explor...

AI Technical Summary

Problems solved by technology

At present, the traditional bird song monitoring method is mainly based on manpower, which is labor-intensive, has a small observation range, is greatly affected by the weather, and cannot record and analyze bird activities in real time.

In addition, field surveys and data analysis often require a lot of time, manpower, and material resources, resulting in high costs and low efficiency.

For island wetlands, there are still problems such as special geographical environment, inconvenient transportation, harsh and changeable climate, etc. As a result, traditional bird survey methods cannot achieve remote monitoring and are difficult to apply to the monitoring of island birds
