基于物联网的环境噪声监测系统研究

为了实现噪声的实时监测、处理和噪声区域可视化,设计了基于物联网(IoT)的噪声监测系统。系统由监控终端、区域中心节点和管理中心组成。监控终端集成了微处理器模块、噪声传感器模块、GPS模块、无线通信模块等。噪声传感器模块和GPS模块用来获取噪声数据信息和噪声源的位置信息并通过无线传输网络将这些信息上传至区域中心节点。区域中心节点用来接收监控终端的数据并上传至服务器。监控管理中心负责噪声数据的发布和绘制噪声地图。实验测试表明:系统可实时准确测量和传输数据,可以为噪声治理提供依据。

Research on environment noise monitoring system based on Internet of things

In order to realize real-time monitoring, processing of noise and visualize of noise region, a noise monitoring system is designed based on Intemet of things （loT）. The system consists of monitoring terminal, regional center node and management center. Monitoring terminal integrates MCU module, noise sensor module, GPS module, wireless communication module and so on. Noise sensor module is used to noise data, and GPS module is used to obtain noise source location and these information is uploaded to regional center node which used for receiving datas in mornitoring terminal and uploaded to the server through wireless transmission network. Monitoring center publishes noise datas and draws noise maps. Experimental results show that the system can accurately measure in real time and transmit data, and can be used as the basis of control noise pollution.
