毕业设计论文-物联网环境下的家居监控系统.doc

PAGE  摘 要 无线传感器网络(WSNs)是由部署在监测区域内的大量廉价微型传感器节点组成，通过无线通信方式形成的一种自组织网络系统。ZigBee是一种适用于工业控制的低速率、低功耗、低成本的射频通信规范，是目前最被看好的无线传感器网络通信方案之一。本课题深入地对ZigBee协议标准做了研究分析，包括各个通信协议层的结构与功能，在此基础上介绍了ZigBee技术应用开发的相关概念，并采用Chipcon公司的单芯片CC2430解决方案设计实现了一个基于ZigBee技术的智能家居监控系统。本课题设计了一种烟雾火灾监测，煤气泄漏监测和家居防盗的无线监测报警系统。传感器终端将检测到的数据通过ZigBee无线通信协议传输给基站节点，基站节点通过RS232串口将数据传输给PC机，最终环境数据显示在PC机的串口调试助手中。 关键字：无线传感器网络；ZigBee；无线通信；无线监测 ABSTRACT Wireless sensor networks are deployed in the monitoring area by the large number of low-cost micro sensor nodes, wireless communication through the formation of a self-organizing network.?ZigBee,an industrial control aimed,low speed,low power consumption and low price telecommunication specification,is one of the most promising technologies for Wireless Sensor Networks. This topic discusses the ZigBee standard then introduces some concepts related to the ZigBee application development.We adopt Chipcon’s single-chip solution CC2430 to build our smart home detect system.This topic has designed a smoke fire monitoring, gas leak detection and monitoring of wireless home security alarm system.The data detected by wireless sensor terminal is transmitted to base station node through ZigBee wireless communication protocol, and then base station node transmits data to PC trough serial port RS232. Finally, environmental data is shown in the screen of PC.
