摘要
当前无线传感器网络技术逐渐成熟,促进了智能农业和精准农业的发展。为获得实地、大范围和实时的农田信息,提出了一种基于ZigBee技术的信息监测系统设计方案,包括硬件平台的设计和系统软件的开发。硬件平台以ATmega128单片机和CC1101射频芯片为核心,主要由数据处理单元、无线模块、传感器控制矩阵、数据存储、供电单元、模拟接口和数字接口等构成。在TinyOS操作系统的开发平台上利用nesC语言实现了传感器节点和汇聚节点的软件开发。对传感器节点主要进行了传感器驱动程序设计,而汇聚节点主要进行了串口通信编程。此外,根据节点不同的工作模式,设计了节点的节能算法。该系统稳定、可靠,满足设计需求。
Wireless Sensor Networks（WSN） technology is becoming increasingly mature nowadays,which will promote the development of smart agriculture and precision agriculture.In order to acquire the field,large-scale and real-time farmland information,an information monitoring system based on ZigBee technology is proposed,including the design of hardware platform and the development of system software.The hardware platform uses ATmega128A MCU and CC1101 chip as the core components,which is constituted by data process unit,radio module,sensor control matrix,data storage flash,power supply unit,analog interfaces and extended digital interfaces.The software development for sensor node and sink node is based on development platform with TinyOS using nesC language.Sensor node design mainly focuses on the sensor driver,and serial communication programming on sink node.According to the node＇s different work modes,energy-saving algorithm is implemented for low-power node.The system is stable,reliable and satisfied with the design requirement.
