【摘要】:針對公路隧道加強(qiáng)照明系統(tǒng)目前使用常規(guī)電力導(dǎo)致高耗電耗能的現(xiàn)狀,設(shè)計一種將太陽光直接用于隧道加強(qiáng)照明中的裝置,既很好地回避了這種陽光輸送機(jī)系統(tǒng)輸出太陽光時有時無穩(wěn)定性差的固有性能缺陷,又能高效利用太陽能以達(dá)到節(jié)能照明的目的。但將普通型陽光輸送機(jī)用于該工程中后又存在著光纖成本高(占系統(tǒng)成本3/4)和光能遠(yuǎn)距離(≥50m)傳輸效率低的應(yīng)用技術(shù)瓶頸,為此研究設(shè)計了極軸跟蹤免光纖式陽光輸送機(jī)。即省去光纖等傳輸介質(zhì),采用極軸式驅(qū)動裝置和閉環(huán)跟蹤控制的關(guān)鍵技術(shù),最終實現(xiàn)將方向不斷變化的太陽光定向從隧道上部拱形空間的空氣介質(zhì)中直接傳輸進(jìn)隧道,然后由安裝于頂部且處于光路不同深度和高度的漫反射鏡組把太陽光散射至路面完成隧道出入段的加強(qiáng)照明。這使太陽光傳輸效率提高到近90%,系統(tǒng)成本同時也下降為原來的1/3。本課題的主要工作內(nèi)容為:(1)極軸跟蹤式陽光輸送機(jī)整機(jī)方案設(shè)計依據(jù)公路隧道太陽光直接照明系統(tǒng)的工程實際要求進(jìn)行整機(jī)的設(shè)計,它主要由安裝在隧道外部的聚光—調(diào)光器、導(dǎo)光器和安裝于隧道內(nèi)部的輔助漫反射鏡組三部分組成。其中聚光調(diào)光鏡及導(dǎo)光鏡各自與相應(yīng)的驅(qū)動控制系統(tǒng)分別組成聚光—調(diào)光器和導(dǎo)光器。重點結(jié)合聚光—調(diào)光器要達(dá)到定點輸出的功能設(shè)計了一種極軸式驅(qū)動裝置;(2)聚光—調(diào)光器極軸式跟蹤控制系統(tǒng)設(shè)計由于隧道拱形截面積限制導(dǎo)致傳輸?shù)墓馔坎荒軡M足路面照明亮度要求,通過對比已有跟蹤方法設(shè)計了配備極軸跟蹤系統(tǒng)的菲涅爾透鏡式聚光—調(diào)光器,實現(xiàn)入射太陽光的跟蹤匯聚并調(diào)節(jié)成增強(qiáng)平行光后定點輸出至導(dǎo)光器的方法有效解決。選用STC12C5A60S2作為控制芯片完成跟蹤系統(tǒng)的光信號采集處理、電機(jī)選型及驅(qū)動控制電路、按鍵調(diào)整顯示電路和對應(yīng)的軟件模塊設(shè)計;(3)基于導(dǎo)光器定向輸出功能的跟蹤方案設(shè)計為驅(qū)動導(dǎo)光機(jī)構(gòu)進(jìn)行光路調(diào)整定向輸出太陽光,采用粗、細(xì)、微調(diào)三層次傳感器組成優(yōu)先級不同的信號采集器結(jié)構(gòu)設(shè)計思路,來解決實際應(yīng)用中由于光信號傳感器安裝于隧道內(nèi)部引起跟蹤系統(tǒng)在正常工作中客觀存在的進(jìn)入信號“盲區(qū)”而導(dǎo)致“脫靶”的問題,以保證系統(tǒng)工作穩(wěn)定性;(4)樣機(jī)各模塊實驗測試及分析總結(jié)對設(shè)計制作的樣機(jī)進(jìn)行了調(diào)試實驗,分析測得數(shù)據(jù)計算菲涅爾透射式聚光—調(diào)光器光學(xué)聚光比約為7.19,跟蹤系統(tǒng)精度約0.1°,且整機(jī)光傳輸效率約達(dá)81%,基本達(dá)到了預(yù)期效果。并與其它公路隧道照明系統(tǒng)比較表明:極軸跟蹤式陽光輸送機(jī)不僅能實現(xiàn)高精度自動跟蹤太陽定向輸出增強(qiáng)型平行光,而且能更高效地傳輸太陽光于隧道出入段路面完成直接照明。該陽光輸送機(jī)作為一種高效率低成本的太陽光導(dǎo)入照明裝置,所采用的極軸式驅(qū)動裝置配合閉環(huán)跟蹤控制技術(shù)以及菲涅爾透鏡式樣機(jī)經(jīng)實驗數(shù)據(jù)驗證均達(dá)到系統(tǒng)目標(biāo)。在用于公路隧道出入段及推廣至地下車庫,住宅陰面房屋等白天也需照明的場所中時,它能充分發(fā)揮照明優(yōu)勢并很好地響應(yīng)節(jié)能環(huán)保的號召,以上工作也為其后期產(chǎn)業(yè)化打下了基礎(chǔ)。
[Abstract]:To strengthen the highway tunnel lighting system currently used in conventional power consumption can lead to high consumption situation, design a direct sunlight for tunnel lighting in strengthening device, which is very good to avoid the sunlight conveyer system output light from the sun when the poor stability of solid performance defects, and efficient use of solar energy to achieve the purpose of energy-saving lighting. But the ordinary type conveyor for the project after the sun has a high cost (the cost of the system for optical fiber 3/4) and light distance (more than 50m) application bottleneck of low transmission efficiency, so the research and design of the polar axis tracking free fiber conveyor. The sun is eliminating the optical fiber transmission medium used polar axis type driving device and key technology of closed loop tracking control, finally realize the sunlight directional changing from the upper part of the tunnel arch space directly from the air medium Enter the tunnel, then the optical path is arranged on the top and at different depth and height of the diffuse reflection mirror group sun light scattering to complete the entry section of Tunnel Pavement Strengthening lighting. This makes the sun light transmission efficiency increased to nearly 90%, the cost of the system also decreased as the main content of this paper is as follows: the original 1/3. (1) the design of the polar axis tracking sunlight conveyer machine design for highway tunnel solar direct lighting system engineering requirements for the machine, which is mainly composed of a mounting condenser - in the tunnel external dimmer, and optical device installed in the tunnel auxiliary diffuse reflector inside the group is composed of three parts. The spotlight dimming mirrors and light microscope respectively and the corresponding drive control system composed of light - dimmer and light guide device. Based on the spot - light regulator to achieve output function design of a shaft type driving device. Set; (2) - light dimmer polaxis tracking control system design as the tunnel arch section because of the limitation of the flux transmission can not meet the requirements of the design of road lighting brightness, Finel lens spotlight - equipped with polar axis tracking system of the dimmer by comparing the tracking method, tracking to achieve convergence of incident solar light and adjust the enhancement method of parallel light output to the light guide device after the effective solution. STC12C5A60S2 is selected as the optical signal acquisition and processing control chip selection and tracking system, motor drive control circuit, software module design circuit and the corresponding button to adjust the display; (3) the design of tracking scheme for optical device based on directional output function for driving the light guiding mechanism for adjusting optical directional output light from the sun, the coarse, fine, fine tune the three level sensors of different priority signal collector structure design, To solve the practical application due to the optical signal sensor installed in the tunnel caused by the internal tracking system exists in the normal work of the signal into "blind" and lead to "Miss", in order to ensure the stability of the system; (4) testing and analysis of each module of the prototype prototype experiments designed by experiment analysis the measured data transmission Finel condenser - dimmer optical concentration ratio is 7.19, precision tracking system is about 0.1 degrees, and the light transmission efficiency of about 81%, basically reached the expected effect. And compared with other highway tunnel lighting system: the polar axis tracking sunlight conveyer can realize high precision automatic tracking solar orientation enhanced parallel light output, and more efficient transmission of solar light in the tunnel exit section of the road to complete the direct lighting. The sunlight conveyer is a kind of high efficient low rate The sun light into the lighting device, the polar axis type driving device with closed-loop tracking control technology and experimental data verified by the Finel lens style reached the system goal. For highway tunnel entrance and exit section and extended to the underground garage, residential houses and other shaded places of lighting will also be the day when it can give full play to the advantages and good response to the call of energy saving and environmental protection, the above work also for the late industrialization laid the foundation.
