摘　　要：环境物联网(Environmental Internet of Things,EIo T)已经广泛地应用于环境监测,在各个地区部署不同类型的EIo T系统是一个长期演进的过程。为了对分布于各地的大规模异构EIo T系统进行统一、有效的管理,通过分析环境监测的特点,并进一步分析了基于EIo T的环境监测系统的感知层、传输层与应用层的特点,提取出了各个环境物联网系统中多种类型的、可用于系统管理的元数据。基于这些环境物联网相关的元数据,构建了一个环境物联网系统统一管理框架。该管理框架通过实时感知应用层中数据存储层中的数据异常状态,可以屏蔽不同EIo T子系统中感知层与传输层的差异,这在一定程度上解决了异构性所带来的问题,可以对大规模、分布式部署的多个不同类型的EIo T子系统进行有效管理。Environmental Internet of Things( EIo T) has been widely applied to environmental monitoring. The existing research of environmental monitoring based on EIo T mostly aim at specific location and specific problem without considering the management of many separate EIo T systems. With the growing number of EIo T system,how to manage these systems centrally and effectively becomes concerned focus. The problem faced by step-by-step deployment of EIo T systems is the ubiquitous heterogeneity in the sensing layer,transmission layer and application layer of EIo T. Through analyzing the characteristic of environmental monitoring and EIo T system,the meta data that can be used for EIo T system management is extracted. A unified management framework of EIo T system is proposed to manage the heterogeneous EIo T system effectively. The heterogeneity problem can be solved by detecting the abnormal data in application layer and blocking the differences in sensing layer and transmission layer among various EIo T systems.
