摘要
在不断发展的物联网、大数据及云计算等技术的交叉融合下,基于无线传感自组网及边缘网关,应用边缘计算,设计实现了一种智慧农业大棚监控系统。系统设计基于物联网架构,传感层以CC2530芯片为核心分别构建了传感型采集节点和控制型节点;采用正三角形网格的节点部署方案,高质量实现了无线传感网构建。边缘网关以STM32F103ZET6 MCU为核心,一方面负责与无线传感器网络中的各节点进行数据通信,完成边缘计算并对网络中的节点进行管理和控制;另一方面通过WiFi、4G/5G等通信模块进行数据的无线传输,把采集到的数据封装处理打包传输到服务器端,实现边缘网关作为连接传感节点与服务器监控中心的相应功能。应用层通过EMQTT服务器和Node-RED搭建云平台构建,用户可以通过PC端、手机端登录数据处理中心的WEB服务器,实现对物联网设备的控制及环境的监测。
Under the cross-fertilization of evolving Internet of Things(IoT),big data and cloud computing technologies,a smart agricultural greenhouse monitoring system is designed and realized based on wireless sensor self-assembling network and edge gateway,applying edge computing.The system design is based on the Internet of Things architecture,and the sensing layer is composed of a CC2530 chip as the core to construct a sensing type collection node and a control type node.The node deployment scheme using a regular triangle grid has achieved high-quality construction of wireless sensor networks.The edge gateway takes STM32F103ZET6 MCU as the core,on the one hand,it is responsible for data communication with each node in the wireless sensor network,completing the edge calculation and managing and controlling the nodes in the network.On the other hand,it carries out the wireless transmission of data through the communication modules such as WiFi,4G/5G,etc.,and encapsulates,processes and packages the collected data for transmission to the server side,so that it can realize the corresponding function of the edge gateway as a connection between the sensing nodes and the server monitoring center.The application layer is constructed by EMQTT server and Node-RED to build a cloud platform.Users can log in to the WEB server of the data processing center through PC and cell phone to realize the control of IoT devices and monitoring of the environment.
