为提高物联网系统的环境适应性、低能耗和高稳定性等质量因素,以设施农业为应用对象,农业环境为测试环境,组建无线传感器网络(WSN),实现网络中关键问题进行研究,包括电量监测管理、影响信号强度变化测试、节点定位算法改进及远程故障诊断等内容。研究复杂环境下影响物联网系统性能的因素之间的关系,对提高物联网技术的推广示范、实现粮食种植的精准化和智能化、提高农民的科技种田素质以及提高土壤的可持续利用能力都有极其重要的作用。
In order to improve the environmental adaptability, low energy consumption and high stability of IoT system, this paper takes facility agriculture as the target and agricultural environment as test environment, and establishes Wireless Sensor Network (WSN) to study the key problems in the network, including Power monitoring management, changes affecting the signal strength test, node location algorithm improvement and remote fault diagnosis and so on. To study the relationship between factors that affect IoT system performance in complex environment, to promote IoT technology promotion and demonstration, to realize the precision and intelligence of grain cultivation, to improve farmers’ quality of farming and to improve the sustainable use of soil Have a very important role.
