摘要
针对物联网网关统一标准尚未制定,无线传感网络(Wireless Sensor Networks,WSN)异构性大,应用场景受限,开发成本高等现状,提出一种应用于农业监控的物联网系统,设计并实现了一种适配多种WSN终端的物联网网关。该网关可以通过GPRS、Wi Fi、以太网多种远程通信模式进行通信,适配ZigBee和Wi Fi传感网络类型终端,满足不同场合和环境的需求。以python集成的Sqlite3作为嵌入式数据库,编程实现数据互操作、数据管理、WSN和传统互联网之间的数据传输,最终形成了一个高集成度的轻量级农业物联网网关。最后给出系统运行结果验证,该网关系统性能稳定、通用性和扩展性强、易于开发和维护。
Internet of Things （IoT） gateway is generally unstandardized. It is usually high cost and poor flexibility to use wireless sensor networks （WSN） because of its high heterogeneity. Due to this situation, an IoT system for agricultural monitoring is proposed, and the gateway, adapting to various WSN terminals, is designed and implemented. The gateway can realize various remote communication modes such as GPRS, WiFi, ethernet. It is easy for this gateway to adapt to ZigBee and WiFi WSN terminals so as to meet the needs of different occasions. Taking Raspberry-Pi-integrated Sqlite3 as an embedded database, the gateway enables the data interoperability, data management and data transfer among WSN and traditional Internet. Finally, a highly integrated lightweight agricultural IoT’s gateway is formed. The run-time results indicate that the gateway features stable system performance, strong universality and scalability, and is easy to develop and maintain.
