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。为提高我国农业用水效率,提出了一种基于ZigBee技术的节水灌溉系统设计方案,包括硬件平台的设计和系统软件的开发。硬件平台以AT-mega128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。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。该系统稳定、可靠,满足设计需求。
Nowadays, Wireless sensor networks （WSN） technology is becoming increasingly mature, which will promote the development of smart agriculture and precision agriculture. In order to improve the efficiency of agricultural water, a water-saving irriga tion 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 CCl101 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 the development platform with TinyOS using nesC language. Sensor node design mainly focuses on the sensor driver, and serial communication programming on sink node. The system is stable, reliable and satisfied with the design requirement.
