基于无线网络的空气污染物检测系统设计

Design of air pollutant detection system based on wireless network

城市空气污染已经对人们的身体健康、生产生活带来了很大危害,空气污染物主要为一氧化碳、二氧化氮、二氧化硫以及烟尘。虽然当前空气污染物检测技术已经比较成熟,但整体自动化程度较低,部分自动化程度较好的设备则价格昂贵,成为其应用推广的瓶颈。为降低设备成本,满足空气质量监测点检测数据的实时传输,采用高度集成的传感器和无线通信模块形成一个个无线通信检测节点,把这些数据最终汇总到控制中心数据库,通过网络查询使用。

Urban air pollution has caused great harm to people＇s life. The main air pollutants are car- bon monxide, nitrogen dioxide, sulfur dioxide and soot. Although the current air pollutants detection technology has been relatively mature, the overall degree of automation is low, some of the more automa- ted is expensive, which become the bottleneck of its practical application. In order to reduce the cost of the equipment and meet the real - time transmission of air quality monitoring data, a high degree of inte- grated sensor and wireless communication module are used to form a wireless communication detection node. Finally, these data will be aggregated to the control center database and be queried using network.
