摘要

本研究提出一種以低功耗藍芽4.0無線通訊技術(Bluetooth Low Energy)所建置之物聯網技術，應用於燈源物聯網系統、藍芽運動手環、呼吸中止警告裝置三個子系統。因環境中之照明需求，故藍芽裝置建置於燈源中，享有從上而下的傳輸過程中必定保持之無障礙的空間，可減低多重路徑(Multipath Fading Effects)之損耗，藉由RSSI訊號強度之定位，可有效增加其定位準確性，達到人員物品監控、燈源控制之目的；本研究所發展之物聯網技術，可藉由智慧型手機、平板電腦等行動裝置配合藍芽訊號傳輸資料，再將其利用Wi-Fi、3G網路上傳至雲端資料庫紀錄、分析，本論文自製藍芽模組以設計定位手環替代手機、平板電腦等行動裝置，進一步延伸開發藍芽運動手環應用於賽事計時，並加上三軸加速度計以反應運動者之運動強度、軌跡等資訊；另一方面，延伸開發奈米多壁碳管設計呼吸感測器應用，特製外殼針對喉部開口患者監測呼吸量，利用藍芽4.0低功耗特性，長期監測患者呼吸狀況，以減少醫護人員之負擔。以上三個子系統雖各別獨立運作，但在未來加以整合，將會具備物聯網的最大互通優勢，改變人們生活習慣。

This thesis proposed a working example on how to design and implement Internet of Things (IoT) of three subsystems for communicating with each other using Bluetooth Low Energy (BLE). The subsystems include wireless sensor network, Bluetooth exercise bracelet, multi-walled carbon nanotubes (MWCNT) base breath counter device. Platform of wireless sensor network embedded in illumination system comprises LED light bulb, tube and socket. The unobstructed space will be maintained from LED to target, which can reduce multipath fading effects. Based on RSSI LED light IOT can provide indoor multi-point positioning and the location data can be sent to the cloud database for further application such as light control. Because the user can’t carry cell phone with him in any time, Bluetooth bracelet is designed to substitute for mobile phone. Further extend the development of exercise bracelet applying to race timekeeping and combining 3-axis accelerometer to react exercise intensity of the player. On the other hand, developing MWCNT breath counter is to combine Bluetooth module for long-term monitoring patient’s apnea. In the future, we will integrate individual subsystems for the greatest interoperability advantage and improving human life!
