【摘要】：隨著社會的發(fā)展，照明節(jié)能已逐漸成為人們的共識。除了采用高效能光源外,在不影響照明需求的前提下,合理地控制光源的輸出光強也是節(jié)能的重要手段之一。太陽光是最適合人類視覺系統(tǒng)的光源，在室內(nèi)照明中合理地利用自然光，不僅可保護人眼視力，而且可以減少了電能消耗，具有廣闊的發(fā)展前景和良好的經(jīng)濟、社會價值。 本文以室內(nèi)照明為研究對象，研究了一種根據(jù)室外自然光照變化而自動調(diào)節(jié)室內(nèi)LED燈管亮度等級的方法。主要研究工作包括： 建立三個相關(guān)的模型：根據(jù)采光節(jié)點的五面采光特性，判斷天氣情況的模型；根據(jù)天氣情況，計算自然光室內(nèi)衰減后的照度值的數(shù)學(xué)模型；根據(jù)人眼感光特性估算所需要的照度值模型。 研究了人工光源調(diào)節(jié)策略：根據(jù)計算出來的室內(nèi)衰減后光照，結(jié)合人眼對光照的需求特性，研究了室內(nèi)人工光源調(diào)節(jié)策略，使室內(nèi)的總照度在滿足人眼需求的前提下，盡可能節(jié)能省電。 具體功能的實現(xiàn)：智能調(diào)光的實現(xiàn)是基于一個室內(nèi)照明管理系統(tǒng)，系統(tǒng)主要由三部分構(gòu)成：Zigbee節(jié)點模塊（包括燈組節(jié)點和光照采集器）、TCP/IP網(wǎng)關(guān)模塊（包括Zigbee節(jié)點和以太網(wǎng)接入器）、管理系統(tǒng)。五面采光節(jié)點間隔一定時間或陽光發(fā)生劇烈變化主動觸發(fā)信息上傳，將采光信息通過網(wǎng)關(guān)模塊上傳電腦管理系統(tǒng)，系統(tǒng)根據(jù)程序算法計算出此時合適的亮度等級，并將控制信息通過Zigbee網(wǎng)絡(luò)發(fā)向LED燈管，實現(xiàn)智能自動的調(diào)節(jié)。 智能調(diào)光算法的驗證：設(shè)計一些實驗，，用數(shù)據(jù)證明本論文研究的根據(jù)自然光照自動調(diào)節(jié)室內(nèi)LED燈管亮度等級的方法具有科學(xué)性、準(zhǔn)確性和合理性。實驗包括：對地理天文參數(shù)準(zhǔn)確性的驗證、采光節(jié)點反映窗口照度準(zhǔn)確性的驗證、自然光照室內(nèi)衰減照度計算值和實測值的比較、最終調(diào)光效果有效性驗證。 概而言之，本文為室內(nèi)智能照明控制提供了一種新方法，通過該方法不僅使照明更加科學(xué)合理，同時節(jié)能效果更加顯著，很好的響應(yīng)了當(dāng)前發(fā)展低碳經(jīng)濟的口號，該系統(tǒng)可廣泛應(yīng)用于辦公樓宇，家庭，學(xué)校，工廠，具有廣闊的市場前景。
[Abstract]:With the development of society, lighting energy conservation has gradually become the consensus of people. Besides using high efficiency light source, it is also one of the important means of energy saving to reasonably control the output light intensity of light source without affecting the lighting demand. Solar light is the most suitable light source for human visual system. The reasonable use of natural light in indoor lighting can not only protect human visual acuity, but also reduce the consumption of electric energy. It has broad development prospects and good economic and social value. Taking indoor lighting as the research object, this paper studies a method of automatically adjusting the luminance grade of indoor LED lamp according to the change of outdoor natural light. The main research work includes three related models: a model to judge the weather condition according to the five surface lighting characteristics of the lighting node, a mathematical model to calculate the illuminance value of the natural light indoor after attenuation according to the weather condition, and a mathematical model to calculate the illumination value after the attenuation of the natural light chamber. The required illumination value model is estimated according to the light sensitivity characteristics of human eyes. This paper studies the adjustment strategy of artificial light source: according to the light intensity after indoor attenuation and the characteristics of the human eye, the adjustment strategy of indoor artificial light source is studied, so that the total illumination of the room can meet the needs of the human eye. Save energy and electricity as much as possible. Realization of specific functions: the realization of intelligent dimming is based on an indoor lighting management system. The system mainly consists of three parts: Zigbee node module (including lamp group node and light collector) and TCP / IP gateway module (including Zigbee node and Ethernet connector), and the management system. The five-sided lighting node has a certain time interval or drastic changes in the sun to trigger the information upload. The lighting information is uploaded to the computer management system through the gateway module. The system calculates the appropriate luminance level according to the program algorithm. The control information is sent to LED lamp through Zigbee network to realize intelligent automatic adjustment. Verification of intelligent dimming algorithm: some experiments are designed to prove that the method of automatically adjusting the brightness grade of indoor LED lamp based on natural illumination is scientific, accurate and reasonable. The experiments include: the veracity of geographical astronomical parameters, the veracity of reflecting window illuminance of daylighting nodes, the comparison between the calculated values of natural illumination indoor attenuation illuminance and the measured values, and the validity of dimming effect. In general, this paper provides a new method for indoor intelligent lighting control, which not only makes the lighting more scientific and reasonable, but also has a more significant energy saving effect, and responds well to the slogan of developing low-carbon economy. The system can be widely used in office buildings, families, schools, factories, with broad market prospects.
