以NFC為基礎的整合型室內、外巡邏系統研究

Abstract

目前的巡邏系統大多是以紙本簽到或是RFID電子簽巡。紙本簽到的方式，容易有紙張遺失、毀損和造假等情況發生，加上人工比對巡邏資料相當耗時;一般RFID電子簽巡作業雖然加速了簽到的作業以及資料電子化，但其功能有限，通常簽到資料需至定點或完成巡邏後才能回傳到後端管理系統進行處理，管理人員並無法掌握即時情況。此外，一般巡邏系統少有室內導引，在較大的室內區域或複雜的樓層，將使巡邏的工作效率降低。 本研究旨在運用內建NFC裝置的Android智慧型手機及其感測功能，發展一套NFC巡邏系統。此外，本研究針對一般巡邏系統中較為忽略的室內導引進行強化。巡檢系統中，管理員先設定NFC感應標籤的地點資訊，並將屬於室內點位的標籤加入室內地圖、樓層、室內位置等其它資訊。接著巡邏員經由網路連線進行人員驗證、巡邏任務下載並使用內建NFC手機進行簽到。巡邏員除了能運用室外地圖進行定位外，也能使用系統中的室內地圖資訊，以瞭解自己及標籤所在的室內位置。當巡邏員簽到時即立刻上傳巡邏紀錄，加上GPS每隔固定時間即提供定位資訊，使後端管理員能夠即時的掌握巡邏狀況。管理員於後端管理中心，能夠獲得目前巡邏的進度和狀況，以針對不同的情況進行適當的處理。Most traditional patrol systems record patrol data on a paper sheet or using a RFID reader. The way of record on paper has many shortcomings such as the recorded paper sheet s are easy to be stolen, also hard to avoid counterfeit data and need to waste much time to trace data. Although using a RFID reader can speedup patrol efficiency, however, most RFID readers doesn’t have enough functions to support the patrol task. For example, a patrol officer can’t upload patrol data in real time, since the RFID readers do not support any communication capability. The study is aimed to develop a patrol system on an Android smart phone with NFC technology. Our system includes an outdoor module and an indoor module. In the outdoor module, we use GPS with Google map to support the patrol routes and using GPS positioning to help the patrol officer to validate his location. In the indoor module, since GPS positioning can’t be used inside a building, we use NFC tag co-worked with the smartphone’s NFC technology to locate the patrol officer’s location using designed indoor map and location information inside an NFC tag. In additions, we develop the back-end manager to receive the smartphone’s recorded patrol data in real time. The patrol manager can handle these patrol data and react different situations for the patrol tasks.
