Background
Noise pollution has become a common problem in modern society, with noise sources present in multiple environments such as industry, transportation, and residential areas. Long term exposure to high noise environments may have negative impacts on human health, therefore it is crucial to monitor noise and take corresponding measures to reduce its impact on people. Introducing appropriate sensors and data processing technologies to monitor and analyze noise levels in real-time, providing scientific basis for relevant departments to formulate governance measures, has become extremely important for its monitoring and management. Therefore, there is an urgent need for a convenient and fast online noise monitoring method to timely detect noise hazards in the process of life, making society better.
System features
The core function of the online noise monitoring system is to collect and analyze noise data. The system collects raw data of environmental noise, such as sound pressure level, frequency, time, etc., through sensors installed at various monitoring points, and conducts real-time analysis to calculate various noise indicators, such as equivalent sound level, percentage sound level, maximum sound level, minimum sound level, etc. These indicators can reflect the intensity, frequency distribution, and trend of noise, providing a basis for noise evaluation and management.
The online noise monitoring system also has transmission and storage functions. The system transmits the collected and analyzed noise data to the monitoring center or cloud platform through wired or wireless means for unified management and storage. The system can also support multiple data formats and protocols for integration and sharing with other information systems. This can achieve the centralization, standardization, and intelligence of noise data, providing convenience for subsequent data processing.

Data transfer scenarios
To the bottom (camera/LED screen/noise online monitoring instrument): Use serial port RS232/RS485/ADC/network port/DI connection method
On top (acoustic environment monitoring platform): The Ailutong RTU600L and the acoustic environment monitoring platform transmit data through 4G/5G/wired network channels
Main functions involved: data collection and data transmission
System principle
- The outdoor LED display screen collects real-time on-site noise data, transmits it to the monitoring center through the network, and displays it on the LED screen.
- The camera integrates dust and noise monitoring, and can expand meteorological parameters to achieve comprehensive environmental monitoring; Video surveillance overlays dust, noise, and surveillance footage to achieve real-time monitoring and video playback of the on-site environment.
- The online noise detector measures and analyzes the noise level in the environment, provides detailed information, and supports the adoption of control measures and intervention measures.
- The data is uploaded to the platform through telemetry terminals, and the platform conducts data analysis to confirm the noise source and analyze the noise.
