麦冬田间环境监测和自动灌溉系统设计与实现

设计并实现了基于无线传感器网络技术的模块化和低功耗的麦冬多元环境数据监测与自动灌溉系统，提出了传感器节点功能与电源相互独立的模块化节点硬件方案，构建了多维度的麦冬田间环境数据监测无线传感器网络以及针对麦冬的灌溉决策模型。系统将采集的麦冬农田环境数据(土壤湿度、地表温度等)结合气象台的温度、湿度以及降雨量等气象数据作为灌溉模型的输入量，进行灌溉决策分析，实现了对麦冬生长环境参数的精确监测和自动灌溉控制。通过在麦冬大田的实际测试结果表明，系统各项功能运行稳定可靠，适用于大中型中药材种植的田间环境连续监测与灌溉控制。

Design and implementation of field monitoring and automatic irrigation system for radix ophiopogonis

System for environmental monitoring and automatic irrigation in the growing field of radix ophiopogonis based on wireless sensor network technology is designed and implemented. The system features the design of hardware modularity which separates the power supply unit from the sensor nodes, the in-field wireless sensor network to monitor the diversifying field environmental data, and the integrating decision-making model for the irrigation control of the field of radix ophiopogonis. In the system, the collected field data, such as the humidity and temperature of the soil, combined with the weather data including the air temperature, humidity, and rainfall from meteorological observatory, are served as the input of the decision-making model to make the decision of irrigation. The decisions actuate the feedback loops to reach the goal of field monitoring and automatic irrigation control. The operation results show that the functions of our system running in the field have high stability and reliability, and the system can be suitably applied to the large area of farmland of medicinal herbs.
