In this paper, a design issue related to the multi-agent based industrial intelligent monitor processing system (IIMPS) in distributed substations is proposed. Multiagent-oriented programming might be the new trend of software programming after object-oriented programming. Multagent-oriented approach uses a higher-level point of view to see the problems. We comment on the characteristics of industrial monitor problems and claim that the multi-agent system (MAS) is a good choice to solve problems with these characteristics. The proposed multi-agent based IIMPS is able to analyze industrial all real messages to assist human operators in identifying associated events. A prototype MAS with JAVA-based GUI used to integrate the existing SCADA system and as the user interface for operators to perform will be discussed in the paper.
