【摘要】：普適計算是繼桌面計算模式后的新興計算模式,它強調物理空間與信息空間的融合。隨著普適計算的發(fā)展,利用情境感知技術為處于工作狀態(tài)下的用戶提供透明的計算服務己成為普適計算領域的研究問題之一。研究表明對于那些需要通過多個規(guī)范化操作完成的活動,往往由于活動執(zhí)行條件的不滿足、用戶異常行為以及實際操作中的不當(如遺漏操作、操作順序錯誤等),而無法實現活動目標,甚或引發(fā)一些安全事故。為了避免上述情形的發(fā)生,就需要對活動執(zhí)行過程進行實時地監(jiān)控,并根據監(jiān)控結果,給用戶提供適合于當前活動狀態(tài)和地點的輔助服務,以達到規(guī)范用戶操作的目的。鑒于以上分析,本文針對普適計算的研究背景,對如何利用與活動有關的情境信息實現活動監(jiān)控進行研究。 本文中考慮的活動是在一定的客觀條件下,經由若干個動作或規(guī)范化操作完成,其執(zhí)行過程中蘊含一定的時序信息,而這些時序信息也為此類活動的監(jiān)控提供了證據與線索。因此,為了根據嵌入在物理空間中傳感器等計算設備感知到的情境來監(jiān)控活動中的異常情況,這就需要準確地描述活動中的時序信息。 本文首先結合所研究的問題,闡述了基于情境感知技術的活動監(jiān)控系統(tǒng)框架。考慮到活動執(zhí)行過程中,情境是動態(tài)變化的,給出了情境模式的概念,并定義了情境模式之間的時序關系,而通過情境模式之間的時序關系能夠清晰地表達活動中的時序信息。根據活動正常執(zhí)行時各情境模式之間的時序關系,歸納了活動實際執(zhí)行過程中的異常模式,這些異常模式的表現形式主要為情境模式之間不滿足對應的時序關系,并給出了判斷異常模式的方法。最后,本文以金相組織分析為研究案例,構建了基于情境時序關系的活動監(jiān)控模型,并針對案例中的鑲嵌操作,根據操作過程中不同時刻的情境取值,來判斷其中的異常情況,驗證了方法的可行性。
[Abstract]:Pervasive computing is a new computing model after desktop computing. It emphasizes the integration of physical space and information space. With the development of pervasive computing, the use of situational awareness technology to provide transparent computing services for users at work has become one of the research problems in the field of pervasive computing. Studies have shown that for activities that need to be performed through more than one normalized operation, user behavior is often abnormal due to unsatisfactory execution conditions of the activity, as well as missteps in actual operations, such as missing operations, Incorrect sequence of operations, etc., without achieving the active goal, or even causing some safety incidents. In order to avoid the above situation, it is necessary to monitor the process of activity execution in real time, and according to the monitoring results, to provide users with auxiliary services suitable for the current state and location of activities, in order to achieve the purpose of standardizing the operation of users. In view of the above analysis, this paper studies how to use situational information related to activities to realize activity monitoring in view of the research background of pervasive computing. The activities considered in this paper are completed by a number of actions or standardized operations under certain objective conditions, which contain certain temporal information in the execution process, and these temporal information also provide evidence and clues for the monitoring of such activities. Therefore, in order to monitor the abnormal situation of the activity according to the situation perceived by the sensor and other computing devices embedded in the physical space, it is necessary to accurately describe the temporal information in the activity. In this paper, the framework of activity monitoring system based on situational awareness technology is introduced. Considering that the situation is dynamic in the process of activity execution, the concept of situational pattern is given, and the temporal relationship between situational patterns is defined. The temporal information of activity can be clearly expressed by the temporal relationship between situational patterns. According to the temporal relationship of each situation pattern when the activity is executing normally, the abnormal patterns in the actual execution process of the activity are summarized. The main manifestation of these abnormal patterns is that the situation pattern does not satisfy the corresponding temporal relation. The method to judge the abnormal pattern is also given. Finally, taking metallographic organization analysis as a case study, this paper constructs an activity monitoring model based on situational temporal relationship, and according to the mosaic operation in the case, according to the situation values at different times in the operation process, to judge the abnormal situation. The feasibility of the method is verified.
