Abstract

We propose a novel framework for building adistributed data acquisition and monitoring system. Ournovel framework is mainly based on XML leverages andOPC (Openness, Productivity, and Connectivity) techniques.Correspondingly, our framework-based system allowseasily aggregating more than the hundreds or thousands ofthe existing OPC DA (Data Access) products in use todaywith new OPC XML-DA products in a flexible system thatcan support to exchange the complex data between the OPCproducts in both the vertical and horizon effectively. Inaddition, the high performance and abilities of reading anddecoding any type of data from hardware I/O devices on theplant floor, which are truly important factors in applicationdesign, are also adequately proposed in this framework. Toprovide a framework for design and implementation of thecontrol and monitoring systems, our framework is proposedas the throughout of standards for interfaces, architectures,and functionalities. This framework is significantly easy toreuse, maintain, and deploy to real industrial applications.In addition to guarantee security problems, we discuss thelevels of security aspects in the control and monitoringsystems considerately. These security aspects provide moresecurity information for technical-level readers. Moreover,the evaluations of our framework and system performanceanalysis indicate that our framework-based system has agood design, an acceptable performance, and is feasible toapply to the area of control and monitoring systems today.
