Wireless Smart Node and Private Cloud Based Environmental Noise Monitoring System

This paper introduces a wireless smart node and private cloud based city ambient noise detection and processing system. With the function of noise data preprocessing and storage, self-diagnostics, and power management, the smart node implements a high-precision, wide-area and  continuous noise data acquisition in urban environment. Data are send back from smart node all-round the city to processing center running on private cloud through public mobile communication networks. Applications on the private cloud manage, analyzing and do a data fusion job with geographic information system. The system requires less setting and maintenance cost, and has more flexibility for update and extension.
