The intelligent monitoring system of wild animal voiceprint helps the construction of the "five bases" collaborative ecological environment three-dimensional remote sensing monitoring system

The intelligent monitoring system of wild animal voiceprint independently developed by the Institute of Zoology, Chinese Academy of Sciences has made important progress, and has been unveiled in the "Endeavor New Era" theme achievement exhibition
as part of the "Five Bases" collaborative ecological environment three-dimensional remote sensing monitoring system of the Ministry of Ecology and Environment.

For a long time, wildlife monitoring has been a difficult point in biodiversity monitoring, especially birds, songbugs and other animal groups
that are not easy to detect by infrared cameras.
Voiceprint recognition provides a new way to
monitor these hidden animals.
In particular, in recent years, the data accumulation of authoritative scientific databases and the wide application of deep learning in voiceprint recognition have accelerated the development of
this field.
The biodiversity informatics research team of the Institute of Zoology, Chinese Academy of Sciences has long been committed to biodiversity data construction and data mining analysis, and has released a number of data products such as the Directory of Chinese Biological Species, the China Biological Map, the China Animal Theme Database and the Biological Record APP, which have been widely used and have accumulated rich experience
in species image and sound recognition 。 Based on the authoritative directory and distribution database, the team collected and integrated animal voiceprint data, combined deep learning and ecological models for joint modeling, and built a bird-based voiceprint intelligent recognition model.
And using the Internet of Things technology, the field pickup sensor and edge computing equipment have been developed, real-time collection of environmental sound for edge computing, real-time return recognition results to the monitoring system for analysis, forming a complete wildlife audio automatic monitoring system
.

At present, the intelligent monitoring system of wild animal voiceprint is adopted by the "Five Bases" collaborative ecological environment three-dimensional remote sensing monitoring system of the Ministry of Ecology and Environment, and is the only equipment system in the system
for biodiversity monitoring based on voiceprint recognition.
The system was first deployed in scenarios such as mobile monitoring vehicles and ground monitoring stations in Tongliao, Inner Mongolia for demonstration and verification
.
Up to now, it has worked stably for more than 2,000 hours, returned nearly 10,000 effective recording data, monitored and identified more than 60 types of ambient sounds, and effectively verified
system performance.
In addition, the research team also provides scientific data support for the "Five Bases" collaborative ecological environment stereo remote sensing monitoring system, supports the key research and development project "Research on Intelligent Identification Technology and Application of Human Interference Activities in Important Ecological Spaces", and promotes the application
of "Five Bases" in biodiversity monitoring.

With the support of several projects of the Chinese Academy of Sciences, the research team has deployed more than 10 sets of intelligent monitoring equipment in various typical habitats and key areas rich in biodiversity, such as Miyun District, Wenyu River Park, Yongdinghe Park and Wildlife Rescue Center in Beijing, and launched the demonstration of intelligent sensing application of
Beijing forest and grassland system 。 Up to now, the system has collected nearly 70,000 effective sound data, monitored and recorded the sounds of more than 200 kinds of birds, which will strongly support the background investigation and long-term monitoring activities of biodiversity in these areas, and also provide a steady stream of animal sound and distribution data for the species diversity database of the Chinese Academy of Sciences, and support the long-term research work
on the spatial pattern and change of biodiversity.

The intelligent monitoring system of wild animal voiceprint is mainly led by Dr.
Lin Congtian of the Animal Adaptation and Functional Genomics Research Group of the Institute of Zoology, Chinese Academy of Sciences, which comprehensively uses the technical advantages of the team in deep learning and a number of scientific databases built by the Chinese Academy of Sciences for a long time, aiming at the key and difficult points in biodiversity monitoring, and has broad application prospects
。 The research and development of the system was jointly funded
by the Strategic Pilot Project (Class A) of the Chinese Academy of Sciences "Earth Big Data Science Project" (XDA19050202), the 14th Five-Year Plan for Network Security and Informatization of the Chinese Academy of Sciences (CAS-WX2021PY-0202) and the National Public Science Data Center for Basic Disciplines.
The test equipment for this project was provided by Habitat (Beijing) Technology Co.
, Ltd.
, thanks to the Institute of Microelectronics of the Chinese Academy of Sciences for providing equipment improvement suggestions
