  • 對於電機技術人才的培養而言,電機操作訓練是乃是一個重要的關鍵因素,如何建立一個良好的電機操作訓練環境,是整個電機人才培育的一個重要課題。傳統的訓練環境其訓練成本昂貴、訓練耗時,不易根據受訓者的需要隨時隨地進行訓練,雖然隨著科技的發展而產生了新的訓練方法,但是仍然存在有許多待突破的問題。
    本研究藉由應用專家系統於電機操作訓練虛擬環境上,建立一個高度智慧、互動、真實且具全球性廣度之訓練環境,可突破傳統訓練環境之限制。研究者首先發展一智慧化的專家系統來監視受訓者於訓練環境中的操作過程,並且適時提供操作上的解釋及示範,接著運用虛擬實境技術開發一高度互動且具真實性之電機操作訓練環境,最後再將此訓練環境建置於網際網路之上,以提供全球性的訓練服務。
    就經濟的觀點來看,本研究之訓練環境可大量節省聘請專業訓練教師授課以及添購訓練設備的費用。就教育的觀點來看,本研究之專家系統扮演訓練教師的角色,提供受訓者在操作上的解釋及示範,虛擬實境則可以讓受訓者安心地在一個沒有危險的環境中接受訓練,網際網路的訓練服務則可讓受訓者突破時空之限制隨時隨地進行訓練。就技術的觀點來看,本研究之訓練環境結合了專家系統、虛擬實境、資料庫、主從式架構、語音合成及語音辨識等技術,各者之間相互配合及溝通的互動方式可供後續研究作為參考。
    在後續發展方面,期望未來能夠將訓練的範圍深入擴大至整個發電廠的電力調度操作。模擬電機會發生的各種異常現象以讓受訓者進行故障排除。利用專家系統來評估受訓者的訓練成果。搭配融入式虛擬實境設備來開發虛擬環境,以提昇受訓者的訓練效果。採用分散式虛擬環境來提供團隊訓練服務。改進語音引擎讓多位受訓者能夠在網路上交談交換學習心得。建構訓練環境的方式能應用在其他專業領域,使訓練的內容更加豐富多樣化。

    Electric machinery operation training is a key factor in training up electrical technicians successfully. How to build a fine training environment for training up electrical technicians is a crucial issue today. Traditional training environments are high-priced and time-consuming, and they are not easy to match the level and pace to the individual needs of every technician. Although new approaches to training have been created since the development of science and technology, there are still many unsolved problems within them.
    In our research, we applied expert system in a virtual environment for electric machinery operation training to provide highly intelligence, interaction and reality for global training environment. It could break through the limits of traditional training environment. Firstly, we built an interactive and realistic training environment using virtual reality technology. Next, we employed expert system to monitor the operations of trainee in virtual environment and to provide operation with explanation and demonstration fitly. Finally, we put training environment on the Internet for global training service.
    From economic viewpoint, our training environment can save a large number of expenses in equipments and trainers for training. From educational viewpoint, expert system plays the role of trainer. It provides explanation and demonstration for operation. Virtual reality allows trainee to be trained with security in a safe environment. Internet training service breaks through the limit of time and space, and therefore trainee can be trained anytime and anywhere. From technical viewpoint, our training environment combines expert system, virtual reality, database, client/server architecture, speech synthesis and speech recognition. Future works can refer to the manners of combination and communication of them.
    In future works, we will extend the range of training to power dispatch of power plant, simulate abnormal phenomena of electric machinery for trouble shooting, employ expert system to evaluate the training achievement of trainee, develop virtual environment with immersive virtual reality devices to improve the effects on training, adopt distributed virtual environment to provide team training service, improve speech engine to allow multi-trainee chating on Internet, and apply the manner of constructing training environment to other domains to enrich the contents of training.
