教室照明节能系统的设计
摘要
随着我国经济的快速增长,能源需求的大幅增加,能源供需矛盾突出,因此,对教学楼照明节能的研究有很大的潜力和现实意义。既能节约能源,又能节约资本,是本设计的主要目的。本系统以单片机为控制中心,兼用LCD显示教室内人数、系统时间、楼门开启时间和楼门关闭时间。本系统分为自动模式和手动模式,自动模式是通过键盘设定楼门开启和关闭时间,根据作息时间、教室里的人数和光照情况自动控制教室灯的亮灭;手动模式是不考虑光照强度、人数和作息时间,人为地控制教室灯的亮灭。同时,本系统还具有定时报警的功能,可以在楼门关闭时间快要到达时,提醒上自习的人赶快离开,从而符合照明节能这一要求。本系统以89S52单片机为控制核心,由DYP-ME003进行人数统计,光线传感器检测教室内的光照强度,时钟芯片DS1302提供了系统的时钟和日期,键盘由五个按键组成,分别用于选择自动模式或手动模式,也用于校正时钟、日期和调整楼门开启时间、楼门关闭时间。本系统电路结构简单,原理清晰,应用性比较强,性价比高,可扩展性比较强,可以被广泛应用于实际。

目前,高校教室照明系统存在严重电能资源浪费现象,在这种背景下对高校教室现有的能源资源调配管理系统进行技术升级改造研究就显得非常重要。高校教学楼照明用电的管理一般有三种模式:一是无专人管理,由学生自行控制开启与关闭;二是利用定时开关,根据作息时间开启和关闭整个教学楼的照明电源;三是由专人负责,即管理人员根据作息时间和天气情况分层送电。教室作为高校教学的重要场所,一般采用开放式管理模式为主,学生基本上无固定的班级教室,无固定的座位;而楼宇管理人员仅负责卫生或保卫工作。由于大多数人的节能意识淡薄,并且强光下人的眼睛对弱光不敏感,在自然光照大于灯具光照的情况下,难以察觉到灯光的存在,因此,造成了白天长明灯,晚上无人也开灯,人少灯全开的浪费现象,这在高校司空见惯。一个教室的长明灯,看起来耗能不大,但从整个学校来看,整个社会来看,却是一个不小的数字,这是一种极大的浪费。造成电能浪费的现象除了节能意识薄弱之外,另一个重要的原因就是节能的硬件设施跟不上。

Design of classroom lighting energy saving system
Abstract
As China's rapid economic growth, substantial increase in energy demand, energy supply and demand contradiction highlights, so that lighting in the building for research has great potential of energy-saving and practical significance. Both conservation of energy and conservation of capital, is the main purpose of this design. This system by single-chip computer control center, and LCD shows number of classroom, system time, the doors opening time and the doors closing time. The system is divided into automatic mode and manual mode, automatic mode through the keyboard to set the doors opening and closing time, according to schedule, the number of classrooms and lighting control lamp light out of the classroom; manual mode does not take into account light intensity, number and time to relax, to artificially control lamp light out of the classroom. At the same time, this system also features timing alarm function, can the doors when closing time is reached, reminded the people get out of study hall, so as to meet the lighting requirements. 89S52 microcontroller to control the core of the system, statistics by the DYP-ME003, the light sensor to detect light intensity within the classroom, provides the system clock and date clock chip DS1302, keyboard is made up of five keys, to select automatic mode or manual mode, respectively, for correction of clock, date and also adjust the door opening time, the door closing time. Circuits of the system structure is simple, the principle clearly applied strong, cost-effective scalability, strong, can be widely used in actual.
