Abstract

[[abstract]]本論文開發一套裝設在自行車車輪的顯像系統,透過裝設在車輪的LED(Light-EmittingDiode)燈條以及人眼視覺暫留(PersistenceofVision)的原理,令自行車在行駛時車輪看起來像是一個圖案,讓使用者在夜間騎乘自行車時可以大幅提升安全性。本論文以嵌入式系統的概念,結合軟體與硬體來開發自行車車輪顯像系統,利用微控制器單晶片搭配自行設計的控制電路與LED顯像電路,讓車輪在旋轉時可以完整呈現一個圖案,再加入藍牙無線網路技術,令使用者可以透過智慧型手機來更換圖案,我們自行設計的手機應用程式可提供六個圖案讓使用者選擇,還可以利用手機拍攝照片顯示。本系統結合了嵌入式系統、藍牙無線網路技術以及Android手機應用程式(ApplicationProgram,APP),為一套自行車在行駛時車輪可顯示出圖案的顯像系統,實驗結果表示本系統可在自行車時速10-30公里時完整顯示圖案,而時速低於10公里則顯示霹靂燈、閃爍燈以及跑馬燈,讓自行車騎士在夜間騎乘時可以得到完整的保護。 / [[abstract]]ThisthesispresentsLED(LightEmittingDiode)imagedisplaysystemthatcandisplaypatternsonthespokesofabicycle.TheproposedsystemofLEDlightsthataremountedonthewheelcanprovidesafetybyproducingabeautifulpattern.ThemaincontrolboardandLEDlightingstripsthatdeterminethedisplayedpatternaredevelopedusingembeddedsystemandelectricalcircuitdesigns.Amobileapplicationprogramisdevelopedtocontrolthelightinghardwareremotely;thesystemcommunicateswiththemaincontrolboardviaaBluetoothwirelessnetworkinterface.Thecyclistcanchangethepatternsusingthemobileapplicationprogramorbypushingbuttonsonthemaincontrolboardbeforeriding.Sixpatternsaredesignedfordisplayusingthissystem,andthepatterncanbemadetochangerepeatedlyatpresentintervals.Thesystemalsoprovidestheapproximatedimagedisplayofactualobjectfromtheshootingofmobilephone.Experimentalresultsrevealthattheproposedsystemperformseffectivelyonthewheeluptoamaximumspeedof30km/hr.Whentherotatingspeedofwheeliswithin10km/hr,thesystemdisplaysseveralfixedimagescircularlyforprovidingthesafetyofbiking.
