摘　　要：分析了面向精准农业应用的无线传感器网络感知节点的功能特性,针对现行节点不能满足精准农业中低能耗、长生命周期及数据准确性需求的问题,搭建了Testmote硬件平台,并基于ATmega1281微处理器实现了传感器模块外围逻辑电路设计,为不同类型通信协议的传感器模块提供即插即用的接入方式。进一步,在深入研究TinyOS 2.x硬件体系结构的基础上,抽象出了传感器模块的驱动体系。最后,根据传感器模块通信协议类型的不同,按照测试、验证、移植的思路,进行通信协议匹配,实现传感器模块的驱动和控制,并成功应用于精准农业大棚监测系统中。Analysed the functions of the sensor node which is used in the precision agriculture application.To point against the situation that the current node couldn＇t reach the necessary of the precision agriculture application such as low energy consumption,long life cycle and data accuracy,based on ATmega1281,a testbed called Testmote was constructed.And the peripheral circuit for the sensor modules was designed to access the modules which used different protocol with a plug and play way.Further,the sensor module driver architecture was abstracted upon the deep study of the TinyOS 2.x.Lastly,according to the differentness of communication protocols,implemented the matching between those protocols,as well as the driver and control of the sensor modules,with the idea of test,validation and transplantation.Now the whole system has been successfully applied in the precision agriculture monitoring application.
