基于LabVIEW的水质监测系统设计与开发

摘要

为实现水产养殖过程中,水质参数监测系统的信号采集简便、数据无线传输以及操作界面简单便捷,且上位机之间能够实现数据共享,设计了一种基于 LabVIEW 的水产养殖水质参数监测系统.该系统以MSP430微控制器为下位机,以nRF905为数据收发模块,中心电脑端(PC机)为上位机,通过LabVIEW构建上位机监控软件,同时采用基于TCP协议的通信方式进行远程通信,LabVIEW的虚拟仪器可以实现计算机数据共享通信功能,从而实现对重要水质参数进行监测以及数据共享.试验过程采集到的数据与标定仪器测量数据,误差在2%以内,丢包率低,能实现上位机之间的数据共享.研究表明,整套系统数据采集结果正常、稳定性良好,系统控制界面简洁,操作简便,且具有性价比高和易扩展等优点.%In order to realize convenient signal collection of water quality monitoring system,data wireless transmission,simple and convenient operation interface,as well as the data sharing between the upper computers,an aquaculture water quality parameter monitoring system based on LabVIEW was designed.This system established the upper computer monitoring software by using MSP430 micro-controller as lower computer,nRF905 as data transceiver module and PC as upper computer through LabVIEW,and achieved remote communication based on TCP protocol.LabVIEW virtual instrument could realize computer data sharing communication function so that it could realize the monitoring of important water quality parameters and data sharing.The error of the experimental data collected by the tests and the calibration instrument is less than 2%,where the packet loss rate is low,and the data sharing between the upper computers can be realized.The results showed that the data collection was normal and stable,the controlling interface of this system is simple and easy to operate,in addition,it has the advantages of high cost performance and extendibility.
