Noise monitoring system helps regulate and control noise emissions in Shenzhen Ma anshan Shamin Industrial Park

In modern industrial production, noise pollution has become an environmental issue that cannot be ignored. In order to effectively control and reduce the impact of industrial noise on the environment and human health, it is particularly important to develop an efficient online monitoring system for industrial enterprise noise. The system can monitor the noise level generated by industrial enterprises in real-time, comply with national or local environmental protection standards, and provide data analysis and alarm functions to assist enterprises in taking corresponding noise reduction measures.

The automatic noise monitoring system for industrial enterprises mainly consists of a noise monitoring substation and a noise automatic monitoring management platform. It monitors and saves noise data, meteorological data, and video data at the factory boundary of industrial enterprises, and automatically records and analyzes the direction and type of sound sources through the sound source recognition function module. It provides detailed and multi-dimensional data for a comprehensive understanding of the noise pollution situation of industrial enterprises and realizes remote supervision.

Equipment composition
1. all-weather outdoor microphone
Outdoor microphones are designed to withstand wind, rain, dust, and interference for long-term continuous outdoor use. The wind cover of outdoor microphones can interfere with the accuracy of noise testing. The outdoor sensor used in our company´s environmental noise online monitoring system has obtained the Chinese Type Approval Certificate (CPA) for measuring instruments. This outdoor sensor can ensure wind, rain, dust, and bird stop prevention while still ensuring that the frequency response of the microphone meets the frequency response requirements for level 2 sensors in GB/T3785-2010.
2. Noise collection and analysis unit
The noise acquisition and analysis unit has signal acquisition and data analysis functions, while ensuring data storage. The noise acquisition and analysis unit of the online monitoring system for environmental noise is not simply equipped with an internal sound level meter for signal acquisition, but uses an industrial grade industrial computer to develop signal acquisition software suitable for automatic noise monitoring systems.
3. Communication unit
Implement data communication from the noise station to the noise monitoring system software server. The online monitoring system for environmental noise adopts 4G wireless communication, which can meet the basic data transmission of the system and ensure stable transmission.
4. Power control unit
To provide power supply, prevent the impact of external power supply jitter on measurement accuracy, and protect the noise monitoring station from external surge attacks.
5.4G wireless communication module
Adopting LTE3GPPRel.11 technology, supporting a maximum downlink speed of 150Mbps and a maximum uplink speed of 50Mbps; At the same time, it is compatible with the Mobile Remote Communication UMTS/HPSA+UC20 module and the Mobile Remote Communication Multi Network Standard LTECat3 module in terms of packaging, achieving seamless switching between 3G and 4G networks. Ensure stable and fast upload of device data.
6. Chassis
The environmental noise in the online monitoring system adopts an all-weather protective box, made of anti-corrosion and anti rust materials, in compliance with IP55 standards, used to place noise collection and analysis units, data acquisition boards, power control units, etc., playing a role in wind, rain, and theft prevention.
7. Recording
Recording, video capture, sound source localization, voiceprint recognition (optional)
