【摘要】 近年来,人们对居住舒适度要求以及国内的建筑总量在不断地提高与攀升,我国的建筑节能问题也日益突出。在所有类型建筑的能耗中,最为广受关注的是大型公共建筑其巨大的单位面积能耗及其严重的能源浪费现象,存在巨大节能潜力。企业可以通过降低能耗来降低运营成本、提高竞争力,而且对经济、社会的可持续发展有良好的促进效应。但是,缺乏系统、可靠、准确的能耗数据的支撑,使得新建建筑和既有建筑在节能设计和节能改造过程中缺乏切实的评价标准。本文中所讨论的大型公共建筑能耗监测系统,目的是建立大型公建的终端能耗信息统计平台;通过分析大型公建用能特点,为节能政策的制定与节能措施的实施提供强有力的科学依据。本文选择以技术路线为主的研究方法,以建筑基础理论与现代通信技术相结合的方式,对大型公建能耗监测系统及西安市节能潜力进行了研究,主要研究工作及结果如下:(1)对大型公共建筑能耗监测系统进行了概述,分析了国内大型公建能耗的现状,对国内之前所提出的能耗监测系统进行了对比分析。并分析了大型公共建筑能耗监测系统对建筑节能所起到的积极作用及意义。(2)对大型公共建筑能耗监测系统进行了系统性的剖析,将其分为能耗信息采集、能耗信息传输、能耗信息储存及能耗信息发布四个子系统。分别对每个系统进行了深入的研究,系统而整体地介绍了大型公共建筑能耗监测系统的整个体系构建。并在以往提出的能耗监测系统的基础上,进行了基于ZigBee无线传感器网络的能耗监测系统的设计。(3)对大型公共建筑电耗分项计量的能耗拆分原理进行了研究,提出了大型公共建筑分项能耗拆分模型及其拆分算法。能耗拆分模型及拆分算法是分项能耗计量的核心内容之一,也是监测数据准确性的关键所在。所以只有提高拆分模型及拆分算法的准确性,才能提供更为精确、可靠的能耗数据。更多还原

【Abstract】 With the rise of the total number of China’s construction and people’s requirements for living comfortment,the problem of building energy control has became more and more prominent in China. Amid building energy consumption, large public buildings drew many attentions with its huge energy consumption per unit area. The situation of energy wasting is serious in large public buildings. And there is a huge saving space. Energy consumption reduction, not only can help companies reduce budget and improve competitiveness, but also can development the sustainable development of the economic and society. Unfortunately, due to the lack of systematic, reliable and accurate building energy consumption data, energy-efficient design of new buildings and energy saving reconstrction for old buildings are the lack support and guidance of data. The energy consumption monitoring system for large public building described in this article,is designed to build a large statistics platform for terminal energy consumption in a building. analysis the specific characteristics of building energy consumption , provide a scientific basis for the implementation of energy saving measures and policies.(1)This paper analyzed and compared a number of previous studies of large public consumption monitoring system . Based on these researches, Proposed another kind of large-scale public power monitoring system which is based on the ZigBee wireless sensor networks. With the new wireless network technology, we can solve the problems during the construction of energy monitoring system. Eliminating the integrated wiring, the construct process will not infact the normal use of the building. (2)In this paper, large public building energy consumption monitoring system has been analyzed systematically. The system has been divided into for four subsystems,which are energy information collection, transmission, storage and dissemination. In order to analysis the integrated archtecture of entire monitoring system,we start this research from each subsystem,and made a detailed explanation for each system’s structure, function, construction. This article can provide great help in the construction and research of the large public building energy consumption monitoring system in the future.(3)This article did some research in the large public buildings’energy consumption split modle and the split algorithm. Energy consumption split modle is aimed the electricity consumption in the energy consumption motoring modle. In order to fide which part of building systems’energy consumption is too high and provide a a solid foundation for energy-saving reconstruction. Split algorithm is a key part of the energy consumption spliting. It is crucial for the accuracy level of data.So, only to improve the accuracy of the split algorithm, can provide the accurate, reliable energy data.更多还原
