隨著ontology應用及語意網的普及，可以預見將有越來越多的應用系統以ontology做為異質系統間之資料交換格式。若現行的分散式監控系統，也能夠以ontology做為程式外部的溝通及資料描述介面，那不同的監控系統彼此要交換資料就會更容易。此外，系統本身若也採用ontology做為與外部溝通的語言，則系統在面對裝置異動或邏輯修改時，將能更快速的反應需求也能更有彈性的面對異動。本研究的目標，便是想要從監控系統中分離出程式應用邏輯及設備描述邏輯，改以ontology的描述方式來取代，進而建立一套以ontology為核心的監控系統，並藉由ontology的導入來改善現行監控系統修改不易及彈性不大的缺點。
為了驗證上面的論述，我們設計了一套以ontology為組態描述的webpanel系統。製造商可以用符合ontology的語法來描述設備的規格，系統整合商也能透過ontology設計監控系統的應用邏輯，結合兩者的ontology描述，便能讓webpanel系統執行監控程序。透過我們的實驗證明，以ontology做為監控系統的應用邏輯描述是可行的。在建構監控系統的過程中，系統整合商能很快的藉由應用系統描述檔完成監控系統的描述，同時webpanel在面對設備故障發生時，也能迅速的透過ontology的搜尋，找到此區域中可用的設備來替代。
對系統整合商來說，建置另一套全新的監控系統只需依據新環境的狀況，適度的調整應用系統描述檔，便可以開始進行監控系統安裝及測試，比起傳統每換一個環境就需要重新撰寫程式的作法會快上許多。另外，藉由ontology描述的特性，可以讓設計的經驗完整的保存下來，供重複使用，對於人才流動快速的企業來說，也可以有效的降低訓練人力及開發系統的時間。
我們希望能夠藉由設計webpanel過程中獲得的相關經驗來簡化傳統監控系統的設計流程及維護時間，將ontology的優點導入相對封閉的監控領域中，讓其更易與其他領域相結合，為人類生活帶來更大的便利。 / As ontology becomes more common and more popular, we are expecting to see an increase in its usage among heterogeneous applications with a need of information exchange. If current distributed monitoring system can utilize ontology as an external communication platform, it will be much easier for different monitoring systems to share and exchange information. In addition, if the systems are able to use ontology as its external communication language, it will be more flexible and faster for the system to make necessary logical changes. The purpose of the research is to differentiate application logic and description logic out of a monitoring system, replace them with ontology, and eventually make it the core of the monitoring system. This could overcome the drawbacks of the current monitoring systems such as lack of flexibility.
In order to justify the objective, we designed a system called webpanel . Manufacturers can use languages that are compatible to ontology to describe the equipment’s specification. System integrators can also use ontology to design system application logic. With these two types of information, we can allow the webpanel to conduct process monitoring. Through our research we found that using ontology to monitor application logic is a good way to construct a flexible surveillance system. During the construction period, system integrators can finish the monitoring description promptly based on the system description. When an equipment failure is encountered, though the search capability of ontology, the system can automatically look for replacement equipment within the area.
From a system integrator’s perspective, rebuilding a brand new monitoring system only depends on some factors in the new environment. With a few minor changes in the system description file, we can deploy a monitoring system shortly. It is highly flexible compared to the traditional way where a new environment will need a new set of programs with customized application logic. Ontology allows us to preserve reusable design experience. Companies that are facing huge turn-over rates can really benefit from it by reducing the cost of training and system development.
We are not the first one to use ontology but we hope that through the design of webpanel, we can acquire experiences to help simplify design in traditional monitoring system and maintenance time. We hope by introducing ontology into the conservative monitoring industry, it can help connect with other industries and bring greater convenience to people’s life.
