摘　　要：工业复杂系统运行中产生的状态信息是测控系统稳定性——系统诊断的重要数据。采用工业泛在无线传感器网络可实时采集多组件的海量状态信息,而信息融合技术能够降低海量测量数据的模糊度,提升系统诊断准确度。本文研究不同融合机制下传感器网络能耗,推导出T时间内网络能耗理论计算公式。通过传感器网络实验系统平台实测分析表明,相同能耗参数的归一化实验数据与理论计算结果吻合较好。实验数据指出,Relay传输需要采取必要冗余机制,避免节点能耗不均衡性引起网络传输性能振荡。Monitoring is necessary for the operation stability of complex system.Industry Ubiquitous Wireless Sensor Networks（IUWSN） can measure,process numerous real-time status messages.To effectively use the scarce energy in the sensor nodes and reliably transmit data packets,the paper studies the energy consumption of the network and the single node theoretically in different ways of data aggregation,and deduces the calculation formula of network energy consumption in a duration of T.The practical test in the experiment system validates the consistence between the calculated results and tested results.According to the test data,some redundancy mechanism is necessary in relay transmission to avoid the performance oscillation of network transmission caused by unbalanced energy consumption.
