基于物联网的大气、水、土壤污染治理监控系统研究

Air,Water and Soil Pollution Monitoring System Based on IOT

为了更及时地预警环境污染数值,设计一种基于物联网的大气、水、土壤污染治理监控系统。在待监控范围内部署传感器,利用Zigbee协议构建无线多跳网络获取大气污染的具体数据;使用GPS获取监控站坐标,比对目标水源历史记录与传感器收集信息,获取水污染监控数值;利用传感器查明土壤环境内主要的污染组分种类、分布规模与污染规律,并引入一维流场二维弥散的分析模型获得土壤污染监控数据。基于此,使用单片机定时对三种污染数据实施A/D转换,组合构建大气、水、土壤污染治理监控系统。

In order to give a more timely warning of environmental pollution values,a monitoring system for air,water and soil pollution control based on the Internet of Things(IPT)is designed.Sensors are deployed within the range to be monitored,and wireless multi-hop network is constructed using ZigBee protocol to obtain specific data of air pollution.GPS is used to obtain the coordinates of the monitoring station to compare the historical record of the target water source with the sensor to collect information,and obtain the monitoring value of water pollution.The main pollution components in the soil environment are identified by sensors,and the distribution scale and pollution law are identified.The analysis model of one-dimensional flow field and two-dimensional dispersion is introduced to obtain soil pollution monitoring data.Based on this,the MCU is used to implement A/D conversion of the three pollution data regularly,and the combination of air,water and soil pollution control and monitoring system is constructed.
