Applied Research Of Large-scale Building Energy Supervision System

China is facing two crunches in the process of sustainable development in terms of energy consumption and environmental pollution.At present,energy shortage and environmental degradation have seriously slowed down the economy development.The importance of energy consumption statistics of buildings is noticed by local governments,and energy management centers are consequently sprung up over the country.The industries data collected by energy management center is sent and processed by the intelligent control program.It will contribute to set up the necessary incentives and disincentives,and promote the refurbishment of building for energy efficiency.As the lack of systematic,the data acquisition,operation and analysis of big data is a widespread problem in existing research.It calls for a technology which is adaptive to various types of building monitoring data by no delay.In consideration of the difficulty of dealing with mass data,the system should fully take advantages of mature technologies such as cloud computing technology,to ensure the system's storage and computing capaability.In the guidance of this comprehensive understanding,this paper sufficiently demonstrates every aspects in energy consumption management and monitoring system for large buildings.It hopes to take effect on promoting building refurbishment to enhance energy efficiency.According the function needed by management system,this paper present various sensor technology and data acquisition technology of monitoring system in detail,and then introduces cloud computing and big data technology to the conceptual design of energy consumption management system,realizing processing function of mass data.The paper analyses the technologies in monitoring system,and introduces the acquisition information required by system,especially focusing on the acquisition technology of power consumption,heat and indoor comfort.It differs from traditional acquisition system which only acquires power consumption,this system owns more comprehensive data and information,and can provide important basis for energy efficiency refurbishment.Considering the technology maturity and the cost,it's impractical to acquisite all kinds of data,therefore the data acquisition ranges are strictly classified in paper.The energy consumption management and monitoring system for large building will be used to track and manage hundreds of buildings,the acquisition points of each building will reach 100 or more,so it's crucial to store and process background data.It's challenge to process big data,and flexible handling mechanism is indispensable.For these reasons,a new monitoring technology base on cloud computing and big data is proposed.Several key points in energy consumption management and monitoring system for large building are analyzed in depth,including data acquisition range,measuring technique,system architecture and program function.Cloud computing technology is successfully introduced.It gives a effective solution not only for processing and calculation of mass data,but also for security and reliability.
