针对多总线分布式控制系统的结构和特点,设计和构造了一种面向多总线分布式控制的分层分布式多Agent系统体系结构。系统由系统控制级Agent、区域控制级Agent和现场Agent组成,采用OPC技术作为整个系统的通信方式,通过引入区域Agent组的概念,采用基于Internet中的域的管理方法来实现对各区域Agent组的有效管理,实现分布协调控制。最后,对各Agent的主要功能进行了设计,并分析了多Agent系统的通信模型和工作过程。
According to the architecture and the characteristics of multi-fieldbus distributed control system, a novel multi- fieldbus distributed control oriented hierarchical and distributed multi-Agent system (MAS) architecture was constructed and designed. The MAS was composed of system control Agent, region control Agent and on-site Agent. It used OPC technology as communication mode throughout the whole system. By introducing the concept of regional Agent group, the system adopted a regional management based on Internet to realize effective management of the regional Agent group and the distributed coordinated control. Finally, the main functions of each Agent were designed, and the communication model and the working process of multi-Agent system were also analyzed.
