This system consists of an outdoor sound array and a high-speed identification computing unit, equipped with monitoring and early warning cloud platform software. Monitor the noise at the construction site, collect sound signals from sound sources, perform signal processing, achieve monitoring and analysis of various construction noises, display analysis results in real time, and transmit the data to the server through wireless modules. The analysis results can be queried through mobile phones and networks.
The boundary noise monitoring system adopts microphone array, which consists of three 1/2 inch microphones arranged at unequal intervals. The delay of noise reaching the microphones in different directions is used to distinguish the direction of noise propagation and receive the noise emitted from the construction site in a directional manner.
·Accurately measure the noise emission at the construction site boundary to resist background noise interference;
·Real time display of noise level on site;
·Connect to the noise monitoring cloud platform, achieve intelligent warning and remote monitoring, network map, real time capture and comprehensive display of monitoring data;
·On-site display screen and dust measurement set optional.
·Shenzhen Metro;
·Tianjin Metro.
