使用膽固醇型液晶玻璃於辦公場所之室內調光系統
為了解決I2C ACK 的問題,作者呂易陞 這樣論述:
本論文設計一種調光系統,結合膽固醇型液晶、自動控制及手動控制,以及燈條,並依據感測系統的數據,自動調整高分子分散式液晶的扭轉角度以及室內光源來達到合適的光照度,或是使用者操作觸控面板,依據需求改變液晶透光度以及燈條的亮度,達成讓室內的人處在舒適的光源下辦公,使眼睛不會因為光源漸弱或漸強而更加疲勞,達到更好工作效率。本論文以盛群HT32F52352微控制器作為主要核心,微控制器以I2C介面接收感測器資料、以傳輸資料至液晶顯示器模組顯示資料及解析觸控模組按鍵,使用觸控模組選擇自動或手動模式。自動模式中,裝置依據過往光照度的感測資料,自動調節玻璃透光度;手動模式中,使用者能選擇液晶玻璃的區塊及自由
選擇的區塊調整其透光度。透過此裝置,希望可以達成白天時能減少太陽光的強度,夜晚時則補足光線不足的問題,以及根據此系統能改善因為光源漸弱或漸強而使得辦公的人眼睛疲勞,並達到調節光源減少能源消耗的效果。在光度感測器距離量測以及測試有效角度時,隨著距離越近,光照度也隨著增加,而隨著角度增加,感測器接收光通量的值逐漸增加,並於90度達到最高。以此確保在不同天氣環境時的光照度範圍都能在有效範圍內。在測量膽固醇型液晶玻璃的特性方面,根據膽固醇型液晶玻璃光線透光度量測的結果顯示,利用電源供應器供給0 V的交流電壓後,穿透度為0 %表示為不透光,逐漸增加交流電壓直到60 V,穿透度達到58 %,以眼睛的觀察為
接近全透明,而根據膽固醇型液晶玻璃反應時間量測結果顯示液晶玻璃區塊的4個區塊的上升時間大概在66~70 ms之間,而下降時間則在40~45 ms的區間內。
具語音控制之電控玻璃應用於室內光源調控
為了解決I2C ACK 的問題,作者賴英傑 這樣論述:
本論文設計及製作一種光源調控系統,結合電控玻璃、語音控制、自動控制及觸控控制,達到室內光源可以根據環境與外部光源自動調整為最適合的亮度,且能讓使用者自行去選擇光源亮度及玻璃開關,並運用創新語音控制方法與手機內建語音助手SIRI做結合,讓使用者能直接跟手機說出相對應之指令,而系統將給予相對應的動作,滿足每個不同需求的人。本系統使用盛群HT66F70A微控制器作為主要控制晶片,利用I2C控制觸控模組來辨認使用之功能,透過每個觸控位置的不同,對應不同的功能,像是開啟系統、手動模式、自動模式及語音模式,而在手動模式中,使用者自己能選擇想要的燈光亮度及玻璃透明度;在自動模式中,透過光照度感測器判斷現在
光源大小做出最適當的調整;在語音模式中,透過跟自己手機的SIRI溝通,並說出相對應的指令而系統就能做出相對應的動作。透過此系統,能夠讓使用者們能不會再因太陽太大需要自己去拉窗簾遮擋,進而節省許多瑣碎的時間,並讓居家智慧化更進一步。
