【摘要】：隨著我國(guó)經(jīng)濟(jì)的高速發(fā)展和社會(huì)的進(jìn)步,能源供需的矛盾越來(lái)越突出。照明用電在電力消耗中的比重逐年提高,然而電力和能源緊缺問(wèn)題一直存在。高等教育學(xué)校是人口高密度聚集區(qū),集教學(xué)、科研以及生活于一體,從而也成為能源消耗大戶。大學(xué)中傳統(tǒng)的照明控制方式由于其管理落后,存在著能源浪費(fèi)、舒適性差、布線復(fù)雜以及燈具壽命短等問(wèn)題,造成了大學(xué)校園中普遍存在“長(zhǎng)明燈”、“無(wú)人亮燈”等電能浪費(fèi)現(xiàn)象。為了緩解用電緊張的狀況,提高高校教室照明效率以及最大限度的降低能源浪費(fèi)已經(jīng)成為必然選擇,因此研究一種教室智能照明控制系統(tǒng)具有重要的意義。 本課題首先將目前高校普遍使用的傳統(tǒng)的日光管和目前我國(guó)大力推廣的LED日光燈管進(jìn)行了對(duì)比,選擇了高效、節(jié)能、環(huán)保、長(zhǎng)壽命的18W T8LED日光燈作為智能照明控制系統(tǒng)中的調(diào)光控制對(duì)像,并且設(shè)計(jì)了一款可調(diào)光18W T8LED日光燈驅(qū)動(dòng)電源,驅(qū)動(dòng)電源采用了PT4107芯片作為驅(qū)動(dòng)器。其次針對(duì)高校教室主要用于學(xué)生上課和自習(xí)學(xué)習(xí)的特點(diǎn),本課題提出一種網(wǎng)絡(luò)化的教室智能照明控制方案,即通過(guò)光照度傳感器采集到的光照度信息和熱釋電紅外傳感器采集到的人員信息傳送給DSP,根據(jù)對(duì)教室不同工作模式和分區(qū)域控制設(shè)計(jì)的需要,DSP產(chǎn)生相應(yīng)的PWM波傳給PT4107的PWMD管腳,從而改變LED的發(fā)光強(qiáng)度,實(shí)現(xiàn)自適應(yīng)調(diào)光的目的,另外DSP通過(guò)CAN總線和上位機(jī)(PC機(jī))進(jìn)行信息交互,DSP既可接收上位機(jī)監(jiān)控系統(tǒng)(VB編寫)發(fā)送的指令又可將采集到的室內(nèi)信息反饋給上位機(jī),以便于工作人員能夠?qū)崟r(shí)了解室內(nèi)照明狀況。PC機(jī)主要負(fù)責(zé)完成對(duì)整個(gè)系統(tǒng)的控制、管理以及監(jiān)視。最后,本課題完成了教室智能照明的控制系統(tǒng)的硬件設(shè)計(jì)和軟件編程。 實(shí)驗(yàn)證明,本課題的設(shè)計(jì)不僅解決了“長(zhǎng)明燈”以及“無(wú)人亮燈”這樣的教室能源浪費(fèi)現(xiàn)象的問(wèn)題同時(shí)也滿足教室內(nèi)人員對(duì)照明的需求,使室內(nèi)照度能夠維持在某一個(gè)水平,讓學(xué)生能夠在保護(hù)視力這樣一個(gè)舒適的環(huán)境里學(xué)習(xí),是具有良好的節(jié)能效果的設(shè)計(jì)
[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.
