NB-IoT架构下的农场虫害监测预警系统

Research on Farm Pest Monitoring and Early Warning System under the NB-IoT Framework

针对广域环境下的农作物虫害防治特性,介绍一种基于窄带物联网(NB-IoT)架构的农场虫害监测和预警系统.系统是在NB-IoT架构下,由ARM Cortex-M7处理器通过局部二值模式提取图像局部纹理特征,进行虫害记录辨别等处理;借助NB-IoT技术将数据上传服务器,通过MQTT协议与WebSocket协议建立通信;在应用层通过网站或移动端APP实现预测和管理的交互.实验结果显示可以持续获得虫害信息,实现监测预警功能,为广域型农作物种植的虫害有效防治提供了技术支持.

According to the preventive characteristics of crop pests in wide-area environment,this paper introduces a farm pest monitoring and early warning system based on Narrow Band Internet of Things(NBIoT)framework.The system operates within the NB-IoT framework,the ARM Cortex-M7 processor extracts the local texture features of the images through the local binary pattern and records the pest identification.Then NB-IoT technology is employed to upload the data to the server and establish communication with the WebSocket protocol through the MQTT protocol.Finally,the interaction between prediction and management is achieved by website or mobile APP in the application layer.The experimental results indicate that the pest information can be obtained continuously to realize the monitoring and early warning function,which provides technical support for the effective control of pests in wide-area crop planting.
