毕业设计（论文）-基于无线传感器网络的无线环境监测模拟装置的设计.doc

摘要
本论文研究的一种基于无线传感器网络的无线环境监测模拟装置的设计,该系统的基本设计思路是通过无线网络将各种监测环境信息的传感器组成无线传感器网络,各节点相互协作将网络覆盖区域中的环境信息采集并处理然后发布给终端(观察者)。论文中先简单介绍了无线传感器网络的相关知识,包括无线传感器网络的体系结构概述、无线传感器网络的应用和无线传感器网络的研究进展等;而后对无线环境监测模拟装置这个系统的网络模型、硬件设计、软件设计进行分析;并介绍了该装置的设计、制作过程;最后对实际制作的系统进行了测试,对测试结果的做了分析,为系统改进提出了建议。

Abstract
In this study, a wireless work-based wireless environmental monitoring simulation device design, the basic design idea is a work to a variety of sensors to monitor environmental information, position of the wireless work, each node in work coverage areas of mutual collaboration will be the environmental information collection and processing and then released to the terminal (observer). Paper briefly describes the relevant knowledge of wireless works, including wireless work architecture overview of the application of wireless works and wireless works research progress; then simulation device for wireless environmental monitoring of the system hardware design, network model, analysis the design of software. Finally, it introduces the design of the device and the process of this production.
