【摘要】 建筑能耗与工业能耗、农业能耗及交通运输能耗共称为民生能耗。在民生能耗中,全球建筑能耗已超过工业和交通方面排在第一位,占到总能耗的41%。我国建筑能耗方面,每年新增建筑面积超过20亿平方米,消耗了全球40%的水泥和钢材,大型公共建筑总面积仅占民用建筑总面积的5%,但耗电量却高达33亿度,相当民用建筑总用电量的50%。本课题针对公共建筑中的重点部分大型医院建筑能耗高、装备多、管理难的特点,从提高医院能源效率、优化能耗管理手段等为切入点进行研究,分析了医院建筑能耗的成因,进而设计开发了基于局域网医院节能监管系统,并实现了对部分能耗装备如医院供水系统及太阳能热水系统的智能监管控制。通过理论分析与实践证明,该基于局域网医院节能监管系统采用BS+CS的方式,模块化设计,实时数据收集采用CS框架,历史数据库采用开源数据库PostgreSQL进行开发,上位机数据采集通过医院局域网与各分站现场通讯设备进行数据通讯,现场数据采集通过现场总线方式与各分支现场通讯设备连接,可以对医院电、水、气等等能耗数据进行实时自动采集、存储与分析。本课题中智能供水控制系统及太阳能热水控制系统采用就地与远程控制相结合的方式,控制模块选用PLC,通讯模块选用GPRS模块。本课题研究虽仅实现了能耗监测模块、供水控制模块及太阳能热水模块等的设计与开发,但未来可以扩展为对医院所有能耗系统进行智能监控,实现了对医院能耗进行实时监测、预警报警、数据存储、数据分析以及医院供水系统监控等功能,能够较好的满足医院后勤保障部门对能耗监测及节能管理方面的需要,为打造绿色医院提供了必要的数据支持,有利于优化医院能源系统的资源配置,从而进一步促进医院快速可持续发展。更多还原

【Abstract】 Building,industrial,agricultural and transportation energy consumption is called people’s livelihood energy consumption.In energy consumption of people,the global building energy consumption has ranged in the first place,exceeding industrial and transportation consumption and accounting for 41% of total energy consumption.As for China’s building energy consumption,newly added construction area is over 2 billion square meters,consuming 40% of of the world’s cement and steel.Large public buildings only accounts for 5% of the total civil construction area,but the power consumption of them is as high as 3.3 billion degrees,which account for 50% of the civil buildings’ total electricity consumption.Large-scale hospitals account for an important part of public constructions,which have a lot of equipment,need massive energy and are difficult to manage.Based on these characteristics,this theory studies the causes of energy consumption in hospital buildings,in order to improve the hospital’s energy efficiency and optimize energy consumption management methods.And then we designed and developed the LAN-based hospital energy-saving supervising system,implementing intelligent control of some energy-consuming equipment,such as water supply system and solar hot water system.The LAN-based hospital energy-saving supervising system adopts BS + CS method and modular design,uses CS framework to realize real-time data collection.The historical database of it was developed using open source database PostgreSQL.Through the data communication between hospital LAN and the site communication equipment,this system can realize host computer data collection.The field bus is in connection with affiliated field communication equipment to collect data on site.By theoretical analysis and practice,we proved that this system can automatically collect,store and analyze hospital’s electricity,water,gas and other energy consumption data in real time.In this project,intelligent water supply and solar hot water control system adopt the combination of local and remote control,the control module uses PLC and the communication module adopts GPRS module.Although this project only implements some modules’ design and development,such as energy consumption monitoring module,water supply control module and solar hot water module,but it can be extended to intelligently control all energy consumption systems in the hospital.This system can realize real-time energy consumption detection of hospital,early alarm and warning,data storage and analysis,water supply system supervising etc.,which can better meet the hospital’s logistics support sector’s needs for energy monitoring and management.All of these can provide necessary data support to construct a environment-friendly hospital and are conducive to optimizing the energy system’s resource allocation,so as to further promote the rapid and sustainable development of the hospital.更多还原
