基于无线传感器网络的空气污染实时监测系统

Air Pollution Real-Time Monitoring System Based on Wireless Sensor Networks

为了解决现有空气污染监测系统所存在的可扩展性差、灵活性不强、应对突发性的空气污染事件的能力弱等问题,开发了一种基于无线传感器网络的空气污染实时监测系统,给出了系统的体系结构和软、硬件实现方法;采用了一种多层次的体系结构,该系统由无线传感器网络监测节点、汇聚节点、监控中心、控制终端、手机终端等组成;该测试系统对空气中一氧化碳及二氧化硫浓度进行了监测,每半小时采集一次监测数据。试验结果表明了该系统的实用性,适用于日常性及突发性的空气污染监测等领域。

In order to solve the problems of existing air pollution monitoring system, which wear weak at scalability, flexibility and the ability to deal with emergency air pollution incidents, a wireless sensor network real-time monitoring system for air pollution was devel- oped. The proposed system architecture and implementation methods of hardware and software were presented. Using a multi--level system architecture , the proposed system consists of wireless sensor network monitoring nodes, sink nodes, the monitoring center, a control termi nal and mobile phone terminal etc. The test system was used to monitor the concentrations of carbon monoxide and sulfur dioxide in the air, the monitoring datas were collected every half-hour. The experimental results shows that the proposed system is practical and can be applied to the routine and emergency air pollution monitoring, etc.
