摘要

在社會結構急速老化，隨著社會人口結構老化，老人失智人口也明顯增加，照顧失智老人的社會成本，將成為下一個青壯年世代非常沉重的負擔。初期失智症狀時常被忽略等原因，一般大眾時常忽略輕度失智老人的照護問題，其中最令人擔心的就是老人家因遊走行為產生的迷路問題。另一方面，因社會的快速變遷，環境日趨複雜，加上社會結構及家庭型態的改變，家長對於兒童的照顧，經常因忙碌的生活產生輕忽，使得兒童的人身安全隱藏危機。目前市面上針對失智老人與孩童的追蹤設備雖然也已經逐漸普及，但在實用性上還是有所不足；而大部分的相關產品都只是定期的對系統伺服器進行位置更新，當親友發送追蹤要求時，系統即回覆被追蹤端上個時間點更新的資料。基於上述問題，本文提出主動更新流程，追蹤端可直接使用Push-Pull Operation直接對被追蹤端發出追蹤更新要求，要求被追蹤端進行定位並回傳給追蹤端，即時且正確的讓追蹤端取得被追蹤端的位置；為了輔助上述的主動更新流程，本文也提出以GPS、3G等定位訊號及基地台資訊做為偵測基礎，在被追蹤端提供電子圍籬偵測功能，透過具備時間參數的電子圍籬框架及失智老人與兒童日常所在地點的分析，通過上述兩種主要功能的實作，提出一個基於雲端平台建立的主動式通知追蹤系統，降低失智老人家與兒童迷路的危險，因本系統主要設計使用在老人與孩童追蹤應用中，因此在被追蹤端的相關設定的畫面，一切以簡易為主，在未來更規劃將所有設定都交由追蹤端進行，除了可以提高系統實用性，實際進行追蹤設備建置也可有效降低設備成本。

With the social structures of rapid aging and population aging, elderly dementia has also increased significantly. Social costs arising from caring for elderly with dementia are bound to heavily burden young adults. Because early symptoms of dementia are often ignored, the general public often overlooks issues related to care of elderly with mild dementia. The most worrying part is elders easily get lost due to their wandering behavior. On the other hand, due to rapid social changes and growing complexity of the environment, coupled with changes in social structure and family pattern, parents often ignore childcare as a result of their busy lifestyle. This in turn exposes children to a hidden safety crisis. Despite the gradual prevalence of elderly with dementia and children tracking devices, their practical uses are still inadequate. Most of related devices only periodically update locations through the system server. When a relative or friend sends a tracking request, the system will only reply with updates on the position of the time of the last tracked end. In view of this problem, automatic update processes were put forth in this stud to enable the tracked end to directly use Push-Pull-Operation to send a request to the tracked end for track updates, requesting the tracked end to position and send it to the tracking end. This will enable the tracking end to obtain real-time and correct position of the tracked end. In order to assist the above-mentioned in actively updating processes, GPS, 3G positioning signals, and base station information were proposed in this study to serve as a basis for detection. At the tracked end, virtual fence detection function is provided. Through the virtual fence framework with time parameters, the analysis of children’s usual whereabouts, and the practical application of the two above-mentioned functions, a cloud platform-based active notification and tracking system was put forward. It will reduce the risk of elderly with dementia and children getting lost. Since the system design application is mainly intended for elderly and children, track end setting frames are kept simple. In the future, all the settings will be done at the tracking end. In addition to enhancing the system practicality, the actual tracking device setup will also effectively reduce equipment costs.
