【摘要】：普適計(jì)算是繼桌面計(jì)算模式后的新興計(jì)算模式,它強(qiáng)調(diào)物理空間與信息空間的融合。隨著普適計(jì)算的發(fā)展,利用情境感知技術(shù)為處于工作狀態(tài)下的用戶提供透明的計(jì)算服務(wù)己成為普適計(jì)算領(lǐng)域的研究問題之一。研究表明對于那些需要通過多個(gè)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(shí)際操作中的不當(dāng)(如遺漏操作、操作順序錯(cuò)誤等),而無法實(shí)現(xiàn)活動目標(biāo),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(jìn)行實(shí)時(shí)地監(jiān)控,并根據(jù)監(jiān)控結(jié)果,給用戶提供適合于當(dāng)前活動狀態(tài)和地點(diǎn)的輔助服務(wù),以達(dá)到規(guī)范用戶操作的目的。鑒于以上分析,本文針對普適計(jì)算的研究背景,對如何利用與活動有關(guān)的情境信息實(shí)現(xiàn)活動監(jiān)控進(jìn)行研究。 本文中考慮的活動是在一定的客觀條件下,經(jīng)由若干個(gè)動作或規(guī)范化操作完成,其執(zhí)行過程中蘊(yùn)含一定的時(shí)序信息,而這些時(shí)序信息也為此類活動的監(jiān)控提供了證據(jù)與線索。因此,為了根據(jù)嵌入在物理空間中傳感器等計(jì)算設(shè)備感知到的情境來監(jiān)控活動中的異常情況,這就需要準(zhǔn)確地描述活動中的時(shí)序信息。 本文首先結(jié)合所研究的問題,闡述了基于情境感知技術(shù)的活動監(jiān)控系統(tǒng)框架�？紤]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(shí)序關(guān)系,而通過情境模式之間的時(shí)序關(guān)系能夠清晰地表達(dá)活動中的時(shí)序信息。根據(jù)活動正常執(zhí)行時(shí)各情境模式之間的時(shí)序關(guān)系,歸納了活動實(shí)際執(zhí)行過程中的異常模式,這些異常模式的表現(xiàn)形式主要為情境模式之間不滿足對應(yīng)的時(shí)序關(guān)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(gòu)建了基于情境時(shí)序關(guān)系的活動監(jiān)控模型,并針對案例中的鑲嵌操作,根據(jù)操作過程中不同時(shí)刻的情境取值,來判斷其中的異常情況,驗(yàn)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.
