Remote Monitoring And Control Research For Equipment In E-Manufacturing

With the development and farther application of information technology and network technology, the world wide economy comes into the era of knowledge economy and network economy. And information becomes the most important factors in e-manufacturing. Then how to integrate the information among provider customer and manufacturing corporation becomes very important. As a result, e-manufacturing mode comes true.The e-manufacturing is a new manufacturing mode facing on the whole supply chain. Which realizes the integration directly among provider customer and manufacturing corporation. And the content of e-manufacturing is not only very abundance but also complexity. A manufacturing automation with powerful function is the base of correct carrying out e-manufacturing. This paper begins with the manufacturing automation system in e-manufacturing.According to the present research condition of manufacturing automation system, the author thinks that the powerful manufacturing automation system is built on the RMC system. A RMC system with High real time^ high credibility and high currency is not only the core of the powerful manufacturing automation system, but also the headspring of the upper application system(Such as CRM and SCM and so on). This paper begins with the broad field of e-manufacturing, then comes to the line of manufacturing automation correctly, at last breaks through from the point of RMC with all energy. According to this, the paper include below contents:In the first chapter, the background and application domain of this paper are worked over in detail. Not only the background, the architecture and the key technology of e-manufacturing, but also the background, the history , the research actuality and the demerit of RMC. And the essentiality of them is discussed. At last, the significance of the research, the major research content and outline of this paper are dissertated briefly.The second chapter works over the theory and architecture of RMC in detail. Firstly, the RMC technology in the whole is described. Secondly, the classifying and compare of RMC are discussed carefully. Thirdly, a new RMC mode called MLMM-RMC is given out, and the architecture and theory of MLMM-RMC mode are investigated at the same time in detail.The third chapter studies the pivotal technology in MLMM-RMCS carefully. Firstly, the standard, the theory and the realizing of serial communication are discussed. Then, the theory and new mode of SMS are worked over carefully, and the development of SMS is investigated particularly. At last the other key technology in MLMM-RMCS is given out briefly.The fourth chapter investigates the communication protocol in RMC in e-manufacturing. Firstly,the arithmetic and realizing of CRC is discussed. Then, the communication protocol in RMC isdescribed in detail, and some special prescribing is given out at the same time. At last, the parametersand instance of communication protocol in RMC based on the NC devices are worked over briefly.According to the treatises of the former three chapters, the fifth chapter introduces theMLMM-RMCS in e-manufacturing based on the MLMM-RMC mode, which is developed by the author. Not only the architecture of this system, but also its functional design. Then the particular design and realizing of each module are presented. At last, a system instance is presented and applications of this system are describedIn the sixth chapter, the total research works of this dissertation are summarized, and further researches are prospected.
