物联网技术在农田环境监测中的应用

为了实现农业的自动化管理，为实现农业精准生产，并为科学研究提供全面信息，设计了基于物联网的农田环境监测系统，系统由传感层、传输层和应用层构成。开发了结构灵活、通用性强的路由和协调器节点，节点通过标准模拟接口与传感器连接，在此基础之上构建了具有高可靠性和灵活性的无线传感器网络，该网络能实时感知作物生长环境信息，并将数据可靠地传输到远端服务器管理系统。田间试验表明：基于物联网农田综合环境信息自动监测系统运行稳定、可靠，为科学预测和科学种植提供了依据。

Application of Internet of Things Technology in Farm Environmental Monitoring

In order to realize the automate management of agriculture, and the implementation of precision production and providing comprehension information for scientific research, the farm environmental monitoring system based on the Internet of Things (IoT) was designed, the system was made up of 3 layers which were sensor layer, transmission layer and application layer, respectively. The modular structure was adopted to develop coordinator node and routing node which had flexible structures and strong versatility, the node connects with sensors through standard analog interface, on the basis of which, high reliability, flexible Wireless Sensor Network (WSN) was built, the WSN could perceive environment information for greenhouse tomato growth in a read time way, and transmits the data to the remote server management system reliably. Field experiments showed that the farm environmental monitoring system based on the Internet of Things was stable and reliable and provided basis for the scientific forecasting and science cultivation.
