摘　　要：提出了一种物联网构架下电能智能计量分层协作体系,由感知层、网络层和应用层构成。在感知层中,采用UHF RFID和传感技术来感知电量参数的变化,获取电能信息;在网络层中,构建一套异构网融合方案,实现不同网络协议的转换,并将计量信息实时可靠地传输给应用层主站系统;在应用层中,提出基于k-means聚类算法的主站海量数据挖掘技术,研究了ORM技术将数据对象持久化到数据库,实现异构数据的集成。指出所提出的物联网构架下的电能智能计量分层协作体系解决了传统电能计量的低效问题。A collaborative system is proposed for the intelligent metering of electricity under the framework of Internet of Things, which is composed of three layers, namely, perception layer, transport layer and application layer. In the perception layer, a method is employed to receive energy information by monitoring electrical changes with UHF RFID and wireless sensor network technology. In the transport layer, an approach is proposed to integrate heterogeneous networks, able to switch network protocols and to transmit measurement information to the master unit. In the applica- tion layer, a massive data mining technology is proposed in master system based on the k-means clustering algorithm. The object relational mapping （ORM） is studied to propagate object persistence to the database and integrate hetero- geneous data. With the hierarchical collaborative system for intelligent metering of electricity under the framework of Internet of Things, a solution can be derived for the problem of inefficiency in traditional electrical measurement.
