摘要
针对现有Zig Bee远程灌溉系统时延过大,结合6Lo WPN网络技术的快速演进,在考虑实现自动化、精准化现代农业的基础上,设计了一种基于6Lo WPAN的水肥一体化智能滴灌系统。该系统采用6Lo WPAN协议实现无线传感器网络(WSN)与IPv4/IPv6网络之间的点到点通信,实现了土壤温度和湿度的实时监测,根据不同作物对湿度的要求远程控制电磁阀进行水或水肥的灌溉。详细描述了系统硬件框架和软件框架实现过程,最后基于Lab VIEW(Laboratory Virtual Instrument Engineering Workbench)软件开发了智能滴灌系统的上位机管理软件。试验结果表明,基于6Lo WPN的WSN与IPv4/IPv6网络可以相互通信,该系统能准确获取土壤湿度和温度数据,通过上位机管理软件可远程控制电磁阀进行灌溉将湿度保持在设定的范围内。系统测试结果表明,6Lo WPN滴灌系统比现用的Zig Bee滴灌系统时延小,有一定的推广潜力。
In view of the large time delay of the existing remote irrigation system based on ZigBee, a drip Irrigation and Fertilizer system based on 6LoWPAN is designed on the basis of Considering the realization of automation and precision of modern agriculture and combining with the rapid advancement of 6LoWPAN. By adopting the 6LoWPAN protocol, this system can realize point-to-point communication between IPv4/IPv6 and real-time monitoring of temperature and humidity of the soil. According to the requirement of different crops to the humidity, the user can control the electromagnetic valve to carry on the irrigation of water or fertilizer. This paper elaborates the hardware structure, software architecture implementation process, and LabVIEW software-perception system master computer management interface development. The experimental results indicate that 6LoWPN and IPv4/IPv6 network can communicate with each other, the system can accurately obtain the soil humidity and ambient temperature data, the electromagnetic valve can be remote control for irrigation through the upper management software to keep the humidity within the set range. The system test results show that the drip irrigation system based on 6LoWPN is less time delay than the drip irrigation system based on ZigBee, which is therefore of great promotional value.
