Oriented Information Technology Manufacturing Equipment Status Information Monitoring System Development

With the advancing process of information strategy in the field of manufacturing,it is obvious that effective data-collecting,storage,transmission,as well as exchangement of on-the-spot status information have decisive importance on concurrent engineering of manufacturing and e-business. Meanwhile,they also have fundamental importance in the informization process of manufacturingOPC technology provides a new solution to standardization of different hardware interfaces. XML,with its great advantages like easy-manipulating,self-description,extensibility,cross-platform and low-cost,is now the prevailing technology for data processing and exchangement. Wireless communication technology is essential to timely data publishing,especially to various mobile handsets,which may contribute to the realization of remote monitoring as well as improve satisfactoriness of customers.In this paper,firstly we analyze the characteristics of modern manufacturing system as well as specify the importance of manufacturing information collecting units,then we put forward the architecture of a modern manufacturing system based on OPC and XML technology,we also discuss in details the key procedures in data-collecting by use of OPC technology,which provide support to the standardization of different hardware interfaces as well as flexibility of data-collecting. Furthermore,we discuss the way of flexible displaying and equipment selection based on the advantages of XML technology. We propose three wireless transmission methods as well as compare them,and implement a demo information query system based on WAP technology. Finally,we develop a prototype system aimed at keeping surveillance of equipment status information,which may give evidence that our solution is both feasible and effective.In the end,after summing up the whole paper,some further researches are also suggested.
