基于WiFi的空气质量实时监测系统设计

摘要

合理规划城镇道路，减少汽车尾气污染成为城市规划建设的重要环节。为了定量统计汽车尾气对城市空气污染程度，实时监测城市道路周边空气质量变化情况，提出一种基于WiFi城市道路空气质量实时监测系统。通过在道路沿线设置多个无线监测节点采集空气污染物数据，经无线网络传输至中心服务器，为城镇道路规划决策的合理性提供理论依据。实验结果表明，空气污染物监测结果稳定可靠，可较好地应用于城市道路空气污染物的检测。%Planning the roads reasonably and reducing pollution from car exhaust have become an important part of the ur⁃ban planning and construction. In order to conduct quantitative statistics for the level of air pollution from motor exhaust and real⁃time monitoring for the change of the air quality around city roads,a WiFi⁃based real⁃time monitoring system for air pollution around city roads is put forward. A number of wireless monitoring nodes are set up to collect air pollutant data along the roads, and transmit the data to central server,which provide a theoretical basis for decision⁃making of urban road planning. The experi⁃mental results show that the air pollutant monitoring result is stable and reliable,and can be better used to detect air pollutants around urban roads.
