摘要

本論文提出一種新的可於行車時即可偵測紫外線指數(UV-Index)之可行方法，其利用紅斑作用光譜求得即時UV-Index值，結合二氧化鈦(TiO2)光感測器及放大電路研製一個偵測電路，且顯示於汽車影像系統。其硬體架構分為車內機與車外機兩大部分。車外機作用為將紫外線B波段輻射通量偵測與轉換；車內機負責紫外線指數運算及顯示於汽車影像螢幕，可隨時供駕駛或任何人查看即時的UV-Index值，輸出形式以不同的色光依紫外線高低不同而顯示不同的顏色在汽車影像系統螢幕，非常簡單明瞭且迅速的便於使用者獲得資訊。其車內機與車外機傳輸透過有線模組進行數據交換。本架構易安裝於各式車型上，操作方法簡易，成本低、體積小、精確度高等優點，且可增加目前汽車影像系統之功能，是具有實用性及商業性的價值之研究。

A new solution to implement to vehicle image system by detecting Erythema Action Spectrum (EAS) , integrate one detected circuit which is designed by TiO2 optical sensor and amplify circuit, and generate UVI to output images real time is an effective method in this thesis. There are two parts in hardware framework: Outer Part Device and Inner Part Device. Outer Part Device is to detect UVB irradiation and then transfer data to Inner Part Device. Inner Part Device is in charge of UVI computing and output images on the display of the vehicle. It is convenient for driver to check real-time ultraviolet index (UVI) and output the different color image with different color light on the screen of vehicle image system, also it is very simple and easy understand for end user to get the information. The data exchange between Outer Part Device and Inner Part Device is used by wire. This system not only has advantages such as easy installation, suitable for each type of vehicle, user friendly, lower cost, compact dimension, great precision and easy portable feature but also could add the function of existed vehicle image system. This research indeed has practicable and commercial value to integrate UVI detector and vehicle image system.
