With the acceleration of urbanization, noise pollution has become an environmental problem that cannot be ignored. According to the "2022 China Noise Pollution Prevention and Control Report" released by the Ministry of Ecology and Environment, according to incomplete statistics, in 2021, about 4.01 million noise complaints and reports were accepted by cities at and above the prefecture level across the country, and noise complaints and reports accounted for 57 in social life9%, and construction noise accounted for 334%, industrial noise accounts for 45%, traffic noise accounts for 42%。
In order to effectively control noise pollution, the intelligent noise monitoring system came into being. Through advanced technical means, the system realizes the real-time monitoring, data analysis and early warning functions of noise, and provides strong support for urban environmental noise control.
1. The composition of the intelligent noise monitoring system
The intelligent noise** monitoring system is built on technologies such as noise monitoring devices, data collectors, and cloud platforms. The system uses highly sensitive acoustic sensors to collect noise data in the environment in real time and transmit the data to the data collector. After the data is processed and analyzed, the collector uploads the results to the cloud platform. Through the intelligent algorithm of the cloud platform, the noise data is analyzed to achieve real-time monitoring and early warning of noise.
2. Functional characteristics of intelligent noise monitoring system
1.Real-time monitoring: The intelligent noise** monitoring system can achieve 24-hour uninterrupted noise monitoring and provide real-time data support for urban environmental noise control.
2.Data analysis: The system has a powerful data analysis function, which can analyze historical data and help the management department understand the trend and law of noise pollution.
3.Intelligent function: voiceprint recognition, by comparing the monitoring value with the preset value, determine the excess noise data, and then use the AI algorithm tool to compare the excess noise recording with the AI data model library, classify the noise source, judge the sound source belongs to the type of life noise, industrial noise, traffic noise, and effectively solve the problem of noise traceability. At the same time, it is equipped with a monitoring subsystem, which can capture the real-time and first-time images of noise, combine noise recording, comprehensively evaluate noise events, and use remote platform to view, which can solve the problem of forensics of excessive sound sources.
4.Early warning function: When the noise exceeds the preset threshold, the system will automatically send an early warning message to remind the management department to take timely measures to prevent further deterioration of noise pollution.
5.Mobile terminal support: Users can view noise monitoring data and early warning information anytime and anywhere through the mobile app, which is convenient to grasp the urban environmental noise situation at any time.
6.Scalability: As technology continues to advance and the needs of city management change, smart noise** monitoring systems should be scalable. The system supports the integration of traffic flow function modules, mainly for real-time monitoring of roads within the region, and automatically perceives the traffic flow and traffic status in the area.
Third, the application value of intelligent noise monitoring system
1.Improving the quality of the urban environment: Through effective monitoring and management of noise, it helps to reduce the level of urban noise pollution and improve the quality of life of residents.
2.Auxiliary decision-making: Based on real-time monitoring data and data analysis results, management departments can formulate more scientific and reasonable noise control policies and measures.
3.Improve the efficiency of governance: The intelligent noise** monitoring system can achieve rapid response and accurate governance, which helps to improve the efficiency of urban environmental governance.
4.Promote sustainable development: By improving the quality of the urban environment, it will help promote the sustainable development of the city and enhance the attractiveness and competitiveness of the city.
5.Enhance residents' awareness of environmental protection: Through the publicity and education function of the intelligent noise monitoring system, residents' awareness and participation in environmental protection can be improved, and a good atmosphere for building a better urban environment can be formed.
