基于ZigBee技术的果蔬大棚土壤墒情管理系统

The Soil Moisture Management System of the Fruit and Vegetable Greenhouse Based on ZigBee Technology

为进一步改善果蔬大棚的种植效率,以ZigBee通信传输技术为切入点,针对大棚土壤墒情管理系统展开研究。在果蔬大棚运行管理机理的基础上,以准确获取并有效辨识出果蔬大棚不同区块的土壤墒情状况为目标,建立ZigBee数据通信模型,进行数据采集处理与精准传输过程分析以及土壤墒情管理系统体系化设计,搭建平台进行土壤墒情管理系统作业状况监测。试验结果表明:基于ZigBee技术的土壤监测试验平台,土壤含水率监测值与实际仪器测得值之间的相对误差控制在5%以内,一致性较好;ZigBee技术应用后,系统的监测数据准确度可提高8.50%,土壤墒情的监测效率整体提高8.10%,满足土壤墒情监测要求,有利于农业大棚种植培养向精准化、智能化方向深度推进。

In order to further improve the planting and cultivation efficiency of the fruit and vegetable greenhouses,ZigBee communication and transmission technology was used as the starting point to study its soil moisture management system.On the basis of the operation and management mechanism of the fruit and vegetable greenhouse,with the goal of accurately obtaining and effectively identifying the soil moisture status of different blocks of the fruit and vegetable greenhouse,ZigBee data communication model was established,data collection and processing,accurate transmission process were analyzed,systematic design of the soil moisture management were carried out,and a platform was built for monitoring the operation status of soil moisture management system of the fruit and vegetable greenhouse,the results showed that the relative error between the monitoring values of the soil moisture content and the measured values of the actual instrument was controlled within 5%,and the consistency was good.Through the application of ZigBee technology,the monitoring data accuracy of the system could be improved by 8.50%,and the monitoring efficiency of soil moisture could be improved by 8.10%.The system meet the requirements of soil moisture monitoring,and would be conducive to the agricultural greenhouse cultivation to the precise and intelligent direction.
