| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 86 === The main purpose of this study is to develop a network-based controlling and moni-toring system of workshop using distributed object environment. In a CIM factory, manycontrollers were integrated to achieve the manufacturing automation by variety of commu-nicating method. In this study, distributed object environment is used in analysis and des-ign of the controlling and monitoring system of workshop. Before implementation, the UML, DCOM notation and OOA/OOD method were employed to model the system. In this study, the controlling and monitoring system of the Vision System and the Remote Sensing System of Automation & Control Center in NTUST was implemented by using Microsoft DCOM. Every Object in the distributed object environment has a trans-parent characteristic of operation. It can be easily controlled and executed parallelly under simplified communication mechanism. The process objects provide automated control ofmanufacturing process. Other objects operate the equipment objects, created by wrapping the opening interface of equipment. The data objects support data persistence, data syn-chronization and data query functions of controlling and monitoring system. With transac-tion server, the data objects can support atomic transaction and rollback functions for ob-ject status. From the practical operation of these machines, it was shown that the distributed object in the method has the following advantages: reusability, scalability and reliability. Besides, many homepage editors can be used to design the User Interface (UI) for system monitoring and controlling. The user will easily access the manufacturing information through any WWW browser on the Internet.
