According to Article 45 of the Noise Law, it is prohibited for any unit or individual to use high pitched loudspeakers in areas where noise sensitive buildings are concentrated in urban areas. Organizing entertainment, gatherings, and other activities in public places such as streets, squares, and parks in urban areas, and using audio equipment that may produce excessive volume that interferes with the surrounding living environment, must comply with the regulations of the local public security organs. Therefore, citizens must comply with laws and regulations to avoid violating them. At the same time, it is necessary to strengthen monitoring of square noise, promptly remind residents of excessive noise pollution, and prevent residents from accidentally violating regulations due to daily activities.
As a public activity venue, noise control is particularly important in squares. In order to effectively manage the noise pollution of the square and improve the user experience of the square, we propose an application solution for the online monitoring system of square noise.
The core measurement module of the noise online monitoring system complies with the Level 2 sound level meter standard, and is interconnected with on-site instruments and meters through Internet of Things technology to complete real-time collection of environmental noise data. The collected data is statistically analyzed and the noise value is calculated. It is a simple outdoor noise automatic monitoring system. It consists of a data display screen, noise sensor, monitoring camera, sound column, microphone, data acquisition and statistical analysis software, 4G/5G wireless transmission module, server cloud platform software, WeChat client and other parts. It has a humanized expression change design, a large measurement range, strong and stable functions, and can remotely view monitoring images beyond the standard, and shout to stop noise pollution behavior on site.
Featured Features
1. Network interruption and transmission continuation: In order to prevent equipment from experiencing network interruption and resulting in monitoring data loss, our company has developed a breakpoint and transmission continuation function. When the equipment detects a network interruption, it automatically saves the monitoring data locally. After detecting that the equipment has recovered from the network, the data monitored during the disconnection period is automatically uploaded to the server for storage.
2. Over limit alarm: The device can set an alarm threshold and support remote setting. When the noise data exceeds this value, the device will automatically alarm and upload it to the supervision platform. The supervision personnel will be reminded through the PC platform or mobile WeChat platform. If the device is equipped with an alarm, it can automatically link with the alarm for sound and light alarm
3. Remote stop call: Equipped with remote stop call function, when the monitoring data exceeds the threshold alarm, regulatory personnel can view the on-site situation from the monitoring video to see if any measures have been taken. If there is no improvement despite exceeding the standard, regulatory personnel can perform remote stop call operation on the APP to order the site to stop noise pollution behavior.
4. Data visualization display
Real time monitoring of community noise data, data uploaded to the backend in real-time
There are various ways to view the noise data details of each point, and administrators can view them through the platform or app.
Alarm information is pushed to the backend, with pop-up alerts and customizable platform alarm reminder audio
Various data charts for convenient statistical analysis of noise data trends
5. Customized design
Equipment styling can be customized according to usage scenarios
