Application Of Object-Oriented Technology On Filter Control System

Recently, with it growing up, Object-Oriented technology applies on all kinds of fields. While in the filed of industrial control, much control systems are analysized and designed by traditional method, which leads to personality heavy , readability poor and maintence inconvenience of PLC's program.In this text, it firstly introduces the technology of PLC's data collecting, controlling, communication , object-oriented analysis(OOA) and object-oriented designing(OOD). Then it brings forward how to apply Object-Oriented technology to Filter Control System. By applying Obiect-Oriented Method, it analysizes and designs the Filter Control System in detail, emphsizing on the PLC's program designing and interface application.and realizes the Filter Controlling System. At last, it makes expection for technical development trends of OO.Filter Control System analyzing and designing by the Object-Oriented method owns the characters of more strong instructure and more excellent readability and maintence of PLC's program, which makes waterworks supply water more safely.
