摘　　要：针对基于IEEE802.15.4a的工业无线传感器监控网络嗅探器的研究和实现,从分析嗅探器原理,介绍了IEEE802.15.4a协议,详细描述了嗅探器的系统结构及设计中对数据包的捕获和过滤过程。给出了针对4种不同过滤设置条件所对应的类定义,可根据用户要求对指定类型、特定站点或设定时间段及包含热点关键字的数据进行捕获过滤,动态显示网络的实时状况。经过试验,本嗅探器完全达到了设计要求,实现了对无线传感器网络的主动侦听监控。The design and implementation of sniffer for industrial wireless network are described, which is based on IEEE 802.15.4a. The principle of sniffer and the protocol of IEEE 802.15.4a are introduced in the paper. The system structure of the sniffer and the process of capture and filtering are described as well. According to four kinds of capture options, the definition of the packet class is given, which make it possible that the sniffer can capture all kinds of data we need and show networks＇ states dynamically. The sniffer can run effectively in the industrial wireless control network environment and meet the requirements of active monitoring for the industrial wireless network.
