  • “專家系統”(Expert System, ES)是具有高實用價值的綜合性學科,也在電腦科學進化史上扮演著極為重要的角色,所以常被列為主要的課程之一。本研究採用專家系統與知識庫系統的設計,運用於智慧型訓練與教育(Intelligence Computer-Assisted Instruction, ICAI),考量傳統氣壓實作迴路複雜、故障維修困難外,加上學習者人數多,教師難以充分指導每一位學習者的每一個操作,因而降低了學習成效。
    系統設計用於氣壓實作之嵌入式專家系統設計,核心係以8051為基底之嵌入式系統晶片,運用專家系統CLIPS的推論結果建構知識規則庫、實驗配管規則庫、錯誤配管診斷規則庫,再將規則庫內容植入嵌入式系統晶片,做成智慧型嵌入式系統晶片,擔任硬體輔助教學的角色,系統晶片與實際氣壓實做配管服務平台結合,透過數位訊號擷取模組診斷學習者的配管過程,診斷與分析學習者的配管模式,提供學習者完善多層次之學習環境。
    使用Silicon Laboratories所開發的嵌入式系統晶片為系統發展核心,提供具專家系統功能的氣壓實做教學平台,學習者透過氣壓實作實際配管服務面板(Reality Wiring Service Panel, RWSP)的數位訊號,偵測學習者實際配管情況,應用嵌入式系統晶片體積小、低耗能、穩定性高、處理速度快的特性來增加系統的真實性、互動性及智慧性,適時地提供輔助教師對學生在實驗過程中的隨時監控、引導、操作、示範,完成互動式氣壓實作訓練服務環境,突破傳統教學思維的範疇,不僅讓學習環境呈現多元化,也助於提昇學習成效。

    Expert systems are knowledge-based systems that emulate expert thought to solve significant problems in a particular domain of expertise. The artificial intelligence represented by expert systems has evolved to be a very useful approach for problem solving. In this research, produces an Intelligence Computer-Assisted Instruction (ICAI) system for Pneumatics, including expert system and knowledge-based systems design. The real-based teaching systems harness the power of information technology to increase interaction between the teacher and the students, to promote individualized learning environments, and to improve the quality of teaching and learning.
    In this research, Silicon Laboratories development is used as the system module. Its’ system kernel uses system on chip microprocessor for 8051 based. According to the expert system inference results, classify knowledge rule base, experiment rule base, and diagnosis rule base. Finally, those expert rules are embedded on microprocessor. The microprocessor properties are real time, interaction and intelligent reasoning. The function of the module in Reality Wiring Service Panel (RWSP) is to receive the signal from signal acquisition module. Students can practice and accustom to the operating and experimenting on this test-platform for the experiment study of pneumatic operation.
    Following the requests of real-time, small-volume, low-loss, high- stability, this research develop an interaction and intelligence system for assist teachers to give a guidance and examples to students. Students could use and practice in the virtual wiring environment to achieve the practice purpose of skill learning.
    Finally, this environment can monitor different kinds of wiring study, and it has the functions of real-time interaction, intelligent guidance and determination for wiring experiment on pneumatic. This system has enhances the efficiency of learning environment and the effectiveness of learning.
