中文摘要：

为实现建筑物内用电设备的实时信息获取、监控及节能优化等目的,提出了以电力线载波技术和Internet技术为核心的建筑设备物联网系统架构,研制了该系统关键部件——物联节点。实现了以太网通信和电力线载波通信间协议转换、数据转发等功能。其硬件主要采用LPC1768ARM7作为主控芯片结合DP83843以太网PHY芯片和MI200E电力线载波芯片完成,结合相应软件实现了建筑用电设备与Internet技术的完美融合。该物联节点的实现使得构建建筑设备物联网这一复杂网络成为可能。

英文摘要：

In order to obtain the real time information, monitor the operation condition and optimize the energy consumption of the electrical equipments in buildings, the architecture of the Internet of building equipments based on the power line carrier technology and Internet technology is presented. And, the core part of this system, named the things node, is developed. Such things node can realize some functions between the Ethernet communication and the PLC communication, such as the protocol conversion, data forwarding, etc. The hardware of the node mainly uses the LPC1768 ARM7 as MCU, while adopting another two types of chips： the DP83843 Ethernet PHY chip and MI200E PLC chip. The realization of the things node makes it possible to construct the Internet of building electrical equipments.
