With the development of society, people's quality of life has gradually improved, and the living environment has begun to have a higher pursuit, noise exists everywhere in our lives, urban parks, residential quarters, squares, bars, KTV, cinemas, there is a risk of noise disturbing the people.
Application scenarios
System composition
Perception layer. It is composed of front-end industrial enterprise noise monitoring system equipment, and transmits the monitoring data to the server through the 4G wireless network.
Platform layer. Real-time data from the perception layer is received for analysis, and big data analysis is used for data processing, aggregation and sorting.
Application layer. Through the platform, the noise pollution of each monitoring point and the entire region can be displayed intuitively and vividly in real time, and a variety of services such as abnormal alarm and regional noise pollution change trend can be provided. The tube platform can operate reliably and save storage space.
Osn Social Life Noise Monitoring Features:
ConstantWarm heating device, disconnected transmission, over-standard alarm, remote stop, over-standard discoloration, over-standard recording, remote calibration, sound source positioning
Noise source identification
Based on the noise source feature database and machine learning technology, the matching and identification analysis of over-standard audio files and abnormal audio files is realized, the feature types of over-standard or abnormal noise sources are identified, and the time labels are marked, including the following types of noise sources:
1) Traffic noise: includes noise emitted by motor vehicles, ships, subways, trains, airplanes, etc. Due to the rapid increase in the number of motor vehicles, traffic noise is the main noise in cities**.
2) Industrial Noise: Noise generated by various equipment in the factory. Industrial noise levels are generally high, which has a greater impact on workers and surrounding residents.
3) Construction noise: Mainly the noise emitted by construction machinery. Construction noise is characterized by high intensity, and most of them occur in densely populated areas, so it seriously affects the rest and life of residents.
4) Living noise: including the noise emitted by people's social activities and household appliances and audio equipment.
5) Natural noise: including birdsong, rain, thunder, typhoon sound, natural noise.
