摘要: 我国目前的水产养殖业中,多采用有线方式进行水质参数的采集。这种系统在实际应用中会遇到布线困难,人工成本高等问题。为解决以上遇到的问题,本设计提出一种基于ZigBee技术的无线水产养殖水质监测系统。采用IT公司的CC2530芯片作为无线网络的数据处理及通讯单元,实现对溶解氧、温度、PH值等参数的采集、处理,并通过串口发送给监控主机。系统采用LabVIEW完成上位机的设计,将节点采集的数据以波形图的方式进行显示。结果表明,本系统功能齐全、运行稳定、界面友好、能很好的满足水产养殖的监测要求。66636

Abstract:China's aquaculture environment monitoring system is mostly adopts cable connection method. The monitoring system of the wired communication mode in the practical application will encounter wiring problems and higher labor costs. In order to solve problems above, this paper presents a wireless aquaculture water quality monitoring system based on ZigBee technology. The monitoring system uses the CC2530 chip as the network data processing and communication unit to complete the collection and processing of the dissolved oxygen,temperature,pH value and so on .Then we use serial port to send the data to PC. The system’s software is designed by LabVIEW and the data is displayed by the way of waveform. The results show that, the system is fully functional and operate steadily. It can also provide a friendly interface.Therefore it can meet the requirements of monitoring of the aquaculture.
