基于WSN的水产养殖水质监测系统设计

Design of Aquiculture Water Quality Monitoring System based on WSN

养殖环境水质参数采集的智能化与信息化是保障养殖安全、提高养殖质量的关键技术之一,本文设计了一款适于水质参数监测的无线传感器网络节点及其网络系统。节点以MSP430F149为处理器,n RF905射频芯片及其外围电路为无线通信模块,BQ2057W充电管理芯片及其外围电路为太阳能充电模块,DOG-96DS溶解氧电极和PHG-96FS p H电极及其信号调理电路为传感器模块,并以该节点为硬件平台编写了通信协议、应用程序和数据监控中心软件,测试了节点功耗、通信距离以及锂电池充电时间。实验结果表明,该系统可实现水质参数的实时监测、实时显示和数据预警,具有远程数据管理功能。

Water quality parameters collected intelligence and information is one of the key technologies that protect farming safety, im- prove breeding quality. A design for parameters of water quality monitoring WSN node and network system. The WSN node based on MSP430F149, nRF905 RF chip and its peripheral circuit for wireless communication module, BQ2057W charging management chip and its peripheral circuit for solar battery module, DOG-96DS dissolved oxygen electrode and PHG-96FS pH electrode and their signal conditioning circuit for a sensor module, and to the node as the hardware platform written communication protocol, application programs and data control center software. Test of the node power consumption, communication distance and lithium battery charge time. The experimental results show that the system can realize the real-time monitoring of water quality parameters, real-time display and data warning, with remote data management function.
