以Linkit-7688 建構物聯網之室內路徑規劃系統

物聯網的趨勢浪潮下，感測器為實現智慧聯網裝置所不可或缺的重要元件，能讓所有獨立的物件實現互聯互通的網路，舉凡穿戴式裝置、智慧型行動裝置、環境監控設備等皆為現在科技熱門應用，與我們生活周遭密不可分。室內路徑規劃得益於成熟的室外導航技術，使室內矢量地圖的研究逐漸發展，這項技術給用戶帶來全新的地理位置服務體驗，為用戶在室內空間裡提供路徑規劃服務。在夜盲症患者眼中的世界，身處於陰暗的環境下，他們是看不清周圍環境的事物，因此對於不熟悉的環境會產生恐懼，希望透過路徑規劃系統，使他們有更多的機會出外行走，擴展其可活動的空間範圍。此系統於老人、女性夜間亦可使用，行走時多一份安全保障。本研究使用Dijkstra’s Algorithm 最短路徑演算法，實現室內地圖跨樓層中任意兩點的尋路系統，以Linkit Smart 7688 Duo微控制單元，結合物聯網設計出一個室內路徑規劃，避免走到陰暗的區域，透過感測器監控整棟大樓的各區域路段情形，能夠確保使用者以明亮路程且距離短的方式抵達目標地點。

Internet of Things in the tide of the trend, sensors are important components for implementing smart networked devices, allowing all independent objects to realize interconnected networks, including wearable devices, smart mobile devices, and environmental monitoring devices and so on, they are popular applications of science and technology, and inseparable from our lives. Indoor path planning benefits from mature outdoor navigation technology, which makes the study of indoor vector map gradually develop. This technology brings users a new location service experience and provides users with path planning services in the interior space. In the eyes of night blindness patients, they can't see clearly surroundings in a dark environment In a dark environment, they are things that don’t see the environment, so they are afraid of an unfamiliar environment. It hoped that through the path planning system, they will have more opportunities to go out and expand the range of their activities. This system can also use in the elderly and women at night, and it is more secure when walking. This study uses shortest path algorithm - Dijkstra's, realize the path to find system of any two points in the indoor map across floors, designing an indoor path plan with Linkit Smart 7688 Duo combined with the Internet of Things. Avoid going to dark areas, we can monitor the entire area of the building through sensors and ensures that the user arrives at the destination in a bright and short distance.
