环境物联网(Environmental Internet of Things, EIoT)已经广泛地应用于环境监测,在各个地区部署不同类型的EIoT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EIoT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EIoT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EIoT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EIoT子系统进行有效管理。
Abstract
Environmental Internet of Things (EIoT) has been widely applied to environmental monitoring. The existing research of environmental monitoring based on EIoT mostly aim at specific location and specific problem without considering the management of many separate EIoT systems. With the growing number of EIoT system, how to manage these systems centrally and effectively becomes concerned focus. The problem faced by step-by-step deployment of EIoT systems is the ubiquitous heterogeneity in the sensing layer, transmission layer and application layer of EIoT. Through analyzing the characteristic of environmental monitoring and EIoT system, the meta data that can be used for EIoT system management is extracted. A unified management framework of EIoT system is proposed to manage the heterogeneous EIoT 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 EIoT systems.
