| In the modern society,with the energy dwindling,energy and resource issues have became an urgent problem for human beings.For sustainable development,the requirement of reducing energy consumption by our nation is raised gradually and the concept of energy saving and emission reduction also gains wide support among people.The electric consumption,merely part of the total energy consumption,contribute greatly to people’s life and social and economic development as well.Statistic shows that the percentage of lighting energy consumption in the building energy consumption is determined,to a large extent,by the lighting control efficiency.As lighting control is a significant branch of modern building automation system,the demand for lighting becomes higher and higher,including not only the needs from daily life,working and studying,but also the demands for comfort and energy saving.The conventional lighting can no longer meet the requirement of people,resulting from its complicated wiring,energy waste and short service life.Therefore,it is of great significance to research the intelligent lighting control for meeting the people’s demand of comfort and energy saving.The foundation of intelligent lighting system is to increase the utilization of natural light,thus it can reduce the energy waste of artificial lighting.Thethesis takes study room as the research object and designs intelligent lighting for it,realizing the function of energy lighting.In this design,cubicspline interpolation is adopted to determine the numbers of people in the study room,combining with the sensor designed by us to decide the light-on or light-off,thus it can eliminate the errors brought by sensor’s failure and wrong operation.Meanwhile,the zoning control is also implemented,which improves the control result,and this system also contains a manual control switch located beside the door entrance,embodying the humanized design.the thesis,drawsintelligentlightinggraphicdesignbyusingCAD,makescontrast between the intelligent lighting design and the ordinaryone,and makes the energy saving analysis as well.Finally in the thesis,the advantagesof the intelligent technology are summarized,anditis proposed that the intelligent lighting technology is the trend of the future.This design has realized energy saving,improved the campus study hall lighting in the future,and played a crucial role,for the students learning environment therefore,intelligent lighting technology in the university will be more widely applied in he field of study hall. |
