臺灣博碩士論文加值系統

本論文設計一種光源調節裝置，結合高分子分散液晶玻璃、自動控制及手動控制，依據偵測系統的回饋，自動改變高分子分散液晶的扭轉角度來達到適宜的光照度，或使用者操作觸控面板，自由調整玻璃透光度，並搭配環保意識，夜間關閉玻璃透光，減緩光害對夜行生物影響。
本裝置以盛群HT32F52352微控制器作為主要核心，以I2C介面接收感測器資料、顯示資料至液晶顯示器模組及解析觸控模組按鍵，選擇自動或手動模式。自動模式中，裝置依據光照度感測資料，自動調節玻璃透光度；手動模式中，使用者能選擇玻璃區塊及其透光度自由調整。透過此裝置，白天時自動提供合適的照度與溫度，夜晚時減少光線透出，為夜行生物爭取生存空間，達成雙贏的局面。

In this paper, a light adjustment device was designed with polymer dispersed liquid crystal(PDLC) glass and both the automatic and manual control, that the twisting angle of the crystal could be automatically changed according to the feedback of the detection system, to achieve appropriate illumination, or the user could operate on the touch panel to freely adjust the light transmittance of the glass. Furthermore, with environmental protection awareness, the light transmittance of the glass was turned off at night to reduce the influence of light pollution on nocturnal organisms.
This device adopted the Holtek HT32F52352 microcontroller unit(MCU) as the main core, and received sensory data through I2C interface. The data was then displayed on the LCD module with appropriate resolution of touch screen module for key input, allowing the user to select either automatic or manual mode. In the automatic mode, the device automatically adjusted the glass transmittance according to the sensor data of light source illumination; as for the manual mode, the user selected the glass block and adjusted its transmittance at will. Through this device, appropriate illumination and temperature could be automatically regulated during the day and light emission was reduced at night; thus, providing a living environment for nocturnal creatures and achieving a win-win situation.
