【摘要】：随着我国经济的高速发展和社会的进步,能源供需的矛盾越来越突出。照明用电在电力消耗中的比重逐年提高,然而电力和能源紧缺问题一直存在。高等教育学校是人口高密度聚集区,集教学、科研以及生活于一体,从而也成为能源消耗大户。大学中传统的照明控制方式由于其管理落后,存在着能源浪费、舒适性差、布线复杂以及灯具寿命短等问题,造成了大学校园中普遍存在“长明灯”、“无人亮灯”等电能浪费现象。为了缓解用电紧张的状况,提高高校教室照明效率以及最大限度的降低能源浪费已经成为必然选择,因此研究一种教室智能照明控制系统具有重要的意义。本课题首先将目前高校普遍使用的传统的日光管和目前我国大力推广的LED日光灯管进行了对比,选择了高效、节能、环保、长寿命的18W T8LED日光灯作为智能照明控制系统中的调光控制对像,并且设计了一款可调光18W T8LED日光灯驱动电源,驱动电源采用了PT4107芯片作为驱动器。其次针对高校教室主要用于学生上课和自习学习的特点,本课题提出一种网络化的教室智能照明控制方案,即通过光照度传感器采集到的光照度信息和热释电红外传感器采集到的人员信息传送给DSP,根据对教室不同工作模式和分区域控制设计的需要,DSP产生相应的PWM波传给PT4107的PWMD管脚,从而改变LED的发光强度,实现自适应调光的目的,另外DSP通过CAN总线和上位机(PC机)进行信息交互,DSP既可接收上位机监控系统(VB编写)发送的指令又可将采集到的室内信息反馈给上位机,以便于工作人员能够实时了解室内照明状况。PC机主要负责完成对整个系统的控制、管理以及监视。最后,本课题完成了教室智能照明的控制系统的硬件设计和软件编程。实验证明,本课题的设计不仅解决了“长明灯”以及“无人亮灯”这样的教室能源浪费现象的问题同时也满足教室内人员对照明的需求,使室内照度能够维持在某一个水平,让学生能够在保护视力这样一个舒适的环境里学习,是具有良好的节能效果的设计
[Abstract]:With the rapid development of economy and social progress, the contradiction of energy supply and demand is more and more prominent.The proportion of lighting power in power consumption is increasing year by year, however, the problem of power and energy shortage has always existed.The higher education school is the population high density gathering area, the collection teaching, the scientific research and the life in one body, thus also becomes the energy consumption big household.Because of its backward management, energy waste, poor comfort, complicated wiring and short life of lamps, the traditional lighting control mode in university has caused the existence of "long light" in the university campus."unlit lights" and other power waste phenomenon.In order to alleviate the shortage of electricity, to improve the efficiency of classroom lighting and to minimize energy waste has become an inevitable choice, so it is of great significance to study a classroom intelligent lighting control system.In this paper, the traditional daylight tube which is widely used in colleges and universities is compared with the LED fluorescent tube which is popularized in our country at present, and the high efficiency, energy saving and environmental protection are selected.The long-lived 18W T8LED fluorescent lamp is used as the dimming control object in the intelligent lighting control system. A dimming 18W T8LED fluorescent lamp driving power supply is designed. The driver uses PT4107 chip as the driver.Secondly, in view of the characteristics of college classrooms mainly used for students' classes and self-study, this paper proposes a networked intelligent lighting control scheme for classrooms.That is, the light intensity information collected by the illumination sensor and the personnel information collected by the pyroelectric infrared sensor are transmitted to the DSP. According to the needs of different working modes and sub-area control design of the classroom, the corresponding PWM waves are generated and transmitted to the PWMD pin of the PT4107.In order to change the luminous intensity of LED and realize the purpose of adaptive dimming,In addition, DSP can exchange information through CAN bus and PC. DSPs can not only receive the instructions written by the upper computer monitoring system (VB), but also feed back the collected indoor information to the upper computer.PC is mainly responsible for controlling, managing and monitoring the whole system.Finally, the hardware design and software programming of the intelligent lighting control system are completed.The experiment proves that the design of this subject not only solves the problem of energy waste in classroom such as "long light" and "unlit light", but also meets the needs of the personnel in the classroom for lighting, so that the indoor illumination can be maintained at a certain level.It is a good energy-saving design to enable students to study in such a comfortable environment as protecting their eyesight.
