Design of smart agricultural greenhouse monitoring system based on wireless sensor network and edge gateway
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 de-sign 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 man-aging 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.
