摘要
汽车尾气是环境污染的重要来源之一,描述了一种使用无线传感器网络对汽车尾气实时在线监测的方法。为实现系统中汇聚节点需要处理大量数据,通信方式多样的功能,提出了一种以ARM7处理器作为汇聚节点控制器的硬件设计方案。分析了基于无线传感器网络的汽车尾气监测系统汇聚节点的设计需求,进而介绍了其系统构成,最后详细说明了汇聚节点的硬件设计与实现。
Nowadays,vehicles＇ off-gases are becoming the main reason for air pollution on urban.In order to detect and analyze the off-gases on-line,a function based on wireless sensor networks is described.Sink node in this system demands two characters,lots of data for handling and functions for communication,so a hardware design based on ARM7 processor is proposed.We analyze the design requirements of the sink node in WSN based on the system of the monitor of vehicles＇ off-gases,then introduce the hardware constitution of the sink node,and at last give a specific design of the sink node.
