摘要
针对农田环境监测面积大、点多、时间长的特点,提出基于物联网架构的农田环境监测系统,系统由传感层、传输层和应用层构成。设计开发了以飞思卡尔MC9S12XS128为微处理器的无线传感器网络节点的硬件电路和太阳能供电系统,编制了协调器与路由器的底层软件,测试了远端服务器与WSN网络单点和多点之间的通信性能。现场试验结果表明:基于物联网的农田环境监测系统,运行稳定、可靠,为科学预测和科学种植提供了依据。
Aiming at the characteristics of farm environmental with measured large area,measured numerous points and long observation time,the farm environmental monitoring system based on the Internet of Things( IOT) was designed. The system was made up of three layers which were sensor layer,transmission layer and application layer,respectively. WSN node hardware circuit based on freescale MC9S12XS128 as microcontroller and node solar photovoltaic power generation system were designed,low layers software system of router and coordinator was programed,communications performance from the remote server to single point and multiple points in WSN was tested. Field experiments showed that the farm environmental monitoring system based on IOT was stable and reliable and provided basis for the scientific forecasting and science cultivation.
