A Novel Framework for Building Distributed Data Acquisition and Monitoring Systems
The paper proposes a novel framework for building a distributed data acquisition and monitoring system. The novel framework is mainly based on XML leverages and OPC (Openness, Productivity, and Connectivity) techniques. Correspondingly, the framework-based system allows easily aggregating more than the hundreds or thousands of the existing OPC DA (Data Access) products in use today with new OPC XML-DA products in a flexible system that can support to exchange the complex data between the OPC products in both the vertical and horizon effectively. In addition, the high performance and abilities of reading and decoding any type of data from hardware I/O devices on the plant floor, which are truly important factors in application design, are also adequately proposed in this framework.
