臺灣博碩士論文加值系統

本論文主要是利用實數型基因演算法 (Real-coded Genetic Algorithm, RGA) 對植物生長燈做最佳化設計。並且由過去文獻我們得知波長、頻率、工作比等参數會影響植物生長，因此我們設計光源刺激系統透過人機介面 (LabVIEW) 能夠彈性調整︰波長、頻率、工作比、光強度。目前市面上已有將調變技術應用於多波長發光二極體 (Light Emitting Diode, LED) 而作成產品，本研究是探討多波長 LED 調變後再同步的技術，同時探討多波長 LED 調變後的相位移設計。透過個人電腦、微處理器以及相關界面電路，本系統允許光波長、頻率 (0 ~ 10 kHz)、工作比 (0 ~ 100%)、光強度與相移比 (0 ~ 360o) 可獨立調整的功能。該植物生長燈透過實數型基因演算法能夠有效改善均勻度和照明效率。對生物體光生理相關研究是一種非常有用的儀器。

In this paper, a real-coded genetic algorithm (RGA) technique is developed for the optimal design of a supplemental lighting system for plant-growth. Moreover, it is known that the parameters: wavelength, frequency, duty ratio and amplitude will affect the plant-growth. We design a functional light stimulation system that can provide a flexible interface to adjust the parameters for users and researchers. There are many products adopts the modulation technique in multiple wavelengths of LEDs (light emitting diodes). Here, we employ the technique of modulation and synchronizing in multi-wavelength LEDs, and design the phase shifts between them. The LED plant- growth system is named as LED modulation light illumination system (LMLIS). Through operations of the personal computer, microprocessor and related interface circuits, the system allows the light quality, light intensity, frequency (0 ~ 10 kHz), duty ratio (0 ~ 100%) and phase shift (0~360o) to be controlled. The optimal design in height and working current of the plant-growth lamp by the RGA shows the improved values of light uniformity and illumination efficiency. The innovatively designed systems are compared favorably with the typical and expert-designed lighting systems. It is concluded that the system is satisfactorily developed to the photosynthesis applications.
