摘要
农业物联网技术应用到农业管理中能够实现农业数字化和精准化,达到增产增效的目的。通过分析温室大棚监控的指标提出基于农业物联网的智能温室标准架构方案:感知控制层由无线传感器模块检测土壤水分、环境温湿度和光照度,利用数据融合的相关知识,并提出无迹卡尔曼(UKF)算法用于感知数据的处理,启动滴灌、喷灌、补光或通风等控制设备;网络传输层以AVR单片机ATMEGA328P构成的Arduino板为控制核心,采用ESP8266 WIFI模块支持数据传输和数据同步,建立了系统层间数据枢纽;终端应用层采用可视化的TLINK物联网平台,可在任何时间和地点查看环境监测数据,同时根据平台监测到的数据,手动或自动启动设备。仿真结果表明:本系统成本低,却具有较高的自动化水平,对进一步提高我国农业种植向智能化方向发展具有指导意义。
The application of Agricultural Internet of things technology to agricultural management can achieve the goal of agricultural digitization and precision,and increase production and efficiency.Through the analysis of greenhouse monitoring indicators,the author puts forward the standard architecture scheme of Intelligent Greenhouse Based on Agricultural Internet of Things.Arduino board composed of AVR single chip ATMEGA328P is used as the control core.The sensing control layer detects soil moisture,environmental temperature and humidity and illumination by wireless sensor module.The related knowledge of data fusion is utilized,and the Unscented Kalman Filter(UKF)algorithm is proposed for sensing data processing.At the same time,according to the data monitored by the platform,the control equipment such as drip irrigation,sprinkler irrigation,light supplement or ventilation is started;ESP8266 WIFI module is used in the network transport layer to support data transmission and data synchronization,and an inter layer data hub is established.The terminal application layer adopts the visual TLINK Internet of Things platform,which can view environmental monitoring data at any time and place,and manually or automatically start the device according to the data monitored by the platform.The simulation results show that the system has low cost and high automation,which has guiding significance to further improve the development of agricultural planting in the direction of intelligent.
