基于无线传感网络的水质监测系统

Water Quality Monitoring System Based on Wireless Sensor Networks

随着当今社会环境水污染问题日趋严重,建立一套水质监测系统已经刻不容缓,基于无线传感网络设计与实现了一种在线水质监测系统。系统构架可以用三级网络模型表示:第一级是底层的水质传感节点,第二级是中层的水质存储节点,第三级是高层的水质监测中心。水质传感节点主要实现对水质数据采集、发送数据到水质存储节点的功能;水质存储节点主要实现将网关的水质数据通过RJ45或者GPRS模块解析到Oracle数据库进行数据存储和显示的功能;水质监测中心主要采用Google Earth数字地图开发水质监测中心平台来展示和监测水质数据,最终完成对水资源的智能化管理。本系统最终能够实现对水质数据采集、无线传输和数据监测,并且与PC机能实时数据通信,整个软件平台运行平稳,实时性较高。

With water environmental pollution problems becoming increasingly serious nowadays,a water quality monitoring system is desperately needed to establish. This thesis describes the design and implementation of an online water quality monitoring system based on wireless sensor networks.System architecture consists of three networks models ： the first level is the bottom of the water quality sensor nodes, the second level is the middle of the water storage nodes, and the third level is the high level of water quality monitoring center. Water quality sensor nodes achieve the function of collecting water quality data and sending data to the water storage nodes. Water storage nodes achieve the function of analyzing water quality data from gateway to the Oracle database for data storage and display via RJ45 or GPRS module. Quality monitoring center develops water quality monitoring center platform to show and monitor water quality data by digital maps of Google Earth, the system completes the intelligent management of water resources. Eventually, the system completes the collection,wireless transmission and data monitoring of water quality data, and real-time data communication with the PC. The whole system has good stability and rapid real-time characteristics.
