Design And Implementation Of University Energy Saving Control And Energy Consumption Monitoring And Management

With the development of the economy society and increasing pressure from environmental resources in China, energy saving and emission reduction situation is difficult. In the process of the promotion of the building areas of energy saving, the problem of the high-energy office buildings and large public buildings has become increasingly prominent. According to statistics, the total area of China’s government office buildings is less than4%of the total area of the town buildings, but annual power consumption accounts for about22%of the total electricity consumption of cities and towns, the annual electricity consumption per square meter in residential buildings is10to20times,1.5to2times comparing to similar buildings in Europe, Japan and other developed countries. The work of the state organ office buildings and large-scale public building energy management, not only directly related to the "Eleventh Five" per unit of GDP energy consumption reduced by20%of the energy-saving strategic objectives, and a strong demonstration effect for the entire energy saving work.Software engineering theory as a guide, describe the process of design and implementation of a campus energy-saving control and energy consumption monitoring and management system. Take full advantage of a campus based network platform, to achieve a large-scale real-time continuous dynamic data acquisition and transmission by types of various types of construction, energy using nature and different department. Build reliability, high efficiency, high degree of sharing energy consumption monitoring database, establishing categorized energy consumption data monitoring, statistical and analysis platform. The system consists of three subsystems:monitoring data subsystem, display subsystem, and back-office management subsystem.The paper describes in detail the design and development of the monitoring data subsystem and display-subsystem two functional modules. The system uses the Unified Modeling Language (UML). Analysis and design the system requirements for each sub-function modules through the use case diagram. Using needs analysis to generate a functional specification and to create the structure of the entire software system. Structures of the database are based on SQL SERVER2008. Based on ASP.NET, the system used C#language to achieve programming of the system. Monitoring data subsystem to achieve real-time energy consumption data collection, transmission, processing, display and other functions and all departments balance inquiry function and alarm function. Analysis and display subsystem provides a summary of energy consumption data, energy consumption data analysis capabilities, energy consumption data reporting capabilities, and the pipe network analysis and other functions.The development and implementation of the system, provides energy using units with a basis for decision making to find out the regularity of all types of building and equipment, regulating energy-using behavior, optimizing internal cost accounting, and enhancing energy-saving management tools of the high-energy buildings and equipment. The development and implementation of the system laid the foundation to improve university energy consumption management level. In the current, China has strongly advocated energy consumption and the environment with less emission. In this background, the development and implementation of the system had high availability and application value.
