| Abstract: | 工具機產業為台灣重要經濟產業之一，其產值於2014年位於全球第七。我國工具機產業面對國際上嚴峻的挑戰，為了確保競爭優勢，研發、升級與創新乃為不可或缺的要件。而發展「智能工具機」為全球工具機產業當前的首要目標，即為在工具機上實現加工決策系統?、自主監控和優化控制、具備線上量測功能、設備學習與自適應能力、機械之間能夠無障礙的進行交流等關鍵技術。透過本論文之研究，冀能整合工具機與物聯網中的EPCglobal結構框架與標準，以進一步達到讓工具機擁有智能化感知的功能、自主監控與決策、機械之間能夠自動分享資訊與交流等這幾項目標。現行EPCglobal結構框架上的應用層級事件（ALE）介面只能處理以無線射頻辨識（RFID）標籤技術為主的感知設備，對於一般的感測器元件並無相對應之應用介面，使得 EPCglobal網路在未來物聯網的產業應用上受到限制。本論文探討如何將傳統EPCglobal結構框架中應用層級事件介面進行擴充，以整合非RFID的感測器設備，讓感測元件能夠藉由應用層級事件銜接到EPCglobal網路上。目前工具機最大的損耗成本為人為操作不當，而造成材料或是設備上的浪費或更換。藉由本論文之研究可以達到對工具機進行全體監測以及警告通知，能夠減少工具機的人力成本以及材料上的耗損，將人為操作錯誤的損失降至最低。本而研究另一目標為將工具機產品應用至物聯網架構中，讓產品產生出符合EPC框架標準下以XML格式為語法的文件與報表，並透過EPCglobal網路在全球供應鏈上做連結，加強產品的可追溯性以及工具機相關的智能化資產監控管理與生產加工上的優化處理
Machine tool industry is one of the most important economic industries in Taiwan, which ranks the seventh in the output value among global CNC machine tool industries in 2014. With severe challenges from the international market, our machine tool industry must rely on R&D, upgrade and innovation to maintain competitive advantage. Currently, global machine tool industry regards the development of intelligent machine tools as its primary goal, focusing on the key technologies for implementing processing decision-making system, self-monitoring and optimized control, online measuring, equipment learning and self-adaption, and smooth exchange between different machines. In view of such trend, this study aims to help integrate CNC machine tool with the architecture framework and standard of EPCglobal network services in Internet of Things, in order to improve machine tool’s functions in intelligent sensing, self-monitoring and decision-making, and automatic information exchange.The Application Level Events (ALE) interface within current the EPCglobal Architecture Framework can only support the sensing equipment which mainly adopts RFID label technology, lacking correspondent application interface for other general sensor components and thus limiting the application of EPCglobal network in the future IoT industry. Toward such issue, this research probes into how to expand the ALE interface within the traditional EPCglobal Architecture Framework to integrate non-RFID sensors and enable sensor components to connect with EPCglobal network via ALE.At present, the major consumption cost of machine tool is spent on the improper manual operation, which leads to the wastage or replacement of materials or equipment. Therefore, this study hopes to prompt relevant businesses to carry out overall monitoring and warning notification for their machine tools, in order to reduce labor cost, material consumption and the loss due to improper manual operation. Another goal of this study is to drive the application of machine tool in IoT structure. In this way, the products can generate the documents and reports that comply with EPC framework standard in XML format, and connect with global supply chain via EPCglobal network to enhance product traceability, intelligent asset monitoring management as well as optimized manufacturing processing. |
