摘　　要：为解决长江三峡库区流域因幅员辽阔、地形复杂难以实施大范围水质监控,设计了一种基于无线传感网络的水环境监测系统.该系统采用无人值守的无线传感网络架构,借助分布式数据采集方式,基于GPRS通过无线网络实现鉴定检测数据的传输,提高了监测精确度,降低了对单个节点传感器的精度要求;大量冗余节点的存在,使得系统具有很强的容错性能;密集分布的节点增大了覆盖的监测区域,减少了洞穴或者盲区.讨论了环境监测系统的结构,设计了监测设备的软硬件系统,基于搭建的系统在线测试环境,给出了主要的实际水环境检测参数的测量数据.测试数据分析结果表明,所设计的系统可以满足三峡库区对水环境参数监测的需要.To overcome the difficulty in implementing the water quality monitor in large-scope resulted form a vast land of endless skies and varied topography area in three-gorges basin of the Yangtze River,a sort of monitoring system of water environment has been designed in the paper based on wireless sensor networks.The system has adopted the architecture of wireless sensor networks of unattended monitoring station,actualized the data transmission by means of distributed data acquisition and through wireless networks based on GPRS,enhanced the monitoring accuracy,reduced the precision demand for single node sensor,made the system own the very strong fault-tolerance performance because of a large number of distribution of redundant nodes,enlarged the covered monitoring area resulted in densely distributive nodes,and reduced the cave or blind area.In the paper the structure of environment monitoring system has been explored,the software and hardware system of monitoring unit designed,and the main actual test data of water environment based on online test environment of constructed system given.The result of test data analysis shows that the designed system could satisfy the demand of three gorges basin for water environment monitoring.
