摘要
立足我国西北地区果园面积广阔且多位于山地、丘陵等地形复杂区域的实际情况,针对传统灌溉方式存在水分利用率、果品产量较低的问题,设计了一种基于LoRa扩频技术与Mesh网络结构的山地果园土壤参数实时监测系统,利用粒子群算法优化部署无线节点的数量并确定节点的坐标位置。以LoRaMesh模块与STM32L052K8低功耗处理器组成无线节点,将采集数据传输并汇聚至上位机进行统计分析。结果表明,该系统具有系统稳定性好、网络可靠性高的特点,实现了水果种植的无线数据采集、远程实时监控、灌溉过程调控,可确保果树的高产优质。
Based on the fact that orchards in the northwest region of China have a vast area and are mostly located in complex terrain areas such as mountains and hills,a real-time monitoring system for soil parameters in mountain orchards is designed based on LoRa spread spectrum technology and Mesh network structure to address the problems of low water use efficiency and fruit yield in traditional irrigation methods.The particle swarm optimization algorithm is used to optimize the deployment of wireless nodes and determine their coordinate positions.A wireless node is composed of LoRaMesh module and STM32L052K8low-power processor to transmit and aggregate collected data to the upper computer for statistical analysis.The results show that the system has the characteristics of good system stability and high network reliability,achieving wireless data collection,remote real-time monitoring,and irrigation process control for fruit planting,ensuring high yield and quality of fruit trees.
