dc.description.abstract | 由於智慧型行動裝置市場的蓬勃發展,個人化服務也更加受到重視。因此,適地性服務(Location Based Services)也成為人們生活中重要的一項議題。而在適地性服務的運作環節中,定位技術扮演著重要的角色,基於使用者個人所在位置,才能提供使用者周邊相關的訊息以及服務。在室外環境下,全球定位系統(Global Positioning System,簡稱GPS)儼然已是最普及也最受歡迎的定位解決方案。然而,在室內的環境下,我們能接收到的衛星訊號相當微弱,也使得全球定位系統在室內環境下無法準確提供使用者所在位置之資訊。因此,室內定位系統的設計也成為現今熱門的研究主題。
在本論文中,我們提供一完整的室內定位系統(Indoor Positioning System,簡稱IPS)解決方案,以簡單且低功率消耗之穿戴式訊號發射機作為室內定位目標,並設計室內定位軟體接收機以佈置於室內環境,接收發射機發送之室內定位訊號。最後,室內定位軟體接收機再對接收之訊號進行數位訊號處理,以達到室內定位之效用。除此之外,為了驗證我們設計的室內定位系統之可行性與可靠度,我們利用軟體定義無線電(Software Defined Radio,簡稱SDR)建置一室內定位系統平台,實際錄製訊號來測試我們所設計的室內定位系統。最後,從現場試驗的結果,我們的室內定位系統可同時相容於三種不同大小的室內環境並提供相當高的定位準確度。 | zh_TW |
dc.description.abstract | As the vigorous development of the market of the smart mobile devices, personal services are gradually getting more and more attention. Because of this, Location based services (LBSs) are becoming a vital part of the life. Location based services refer to provide the services or the relevant information around the user. Hence, in order to find the location of the user at the right time, positioning technologies play an important role in this application. Undoubtedly, Global Positioning System (GPS) is the most popular positioning technology in the outdoor environment. However, due to the signal of the satellite is too weak in the indoor environment, the global positioning system can not provide accurate location of the user. Therefore, the design of the indoor positioning system (IPS) has become a hot research topic nowadays.
In this thesis, we provide the complete solution of the indoor positioning system. We design a simple and low power consumption wearable signal transmitter to be the indoor positioning target. And, we design and arrange several synchronized indoor positioning software receivers in the indoor environment to receive the signal. Finally, through the digital signal processing, we can find the location of the target. In addition, for the purpose of validating the reliability and feasibility of our indoor positioning system, we use software defined radio (SDR) to build an indoor positioning system platform and record the signal practically. From the results of the field trial, our indoor positioning system is compatible with three indoor environments with different size and can provide high accuracy of positioning. | en |
