摘 要: 基于多Agent系统理论,提出一种分布分层的水电厂预知维护的多Agent系统模型,该模型由数据采集层、数据处理层、诊断与预诊断层以及维护决策层组成。针对系统中维护Agent,设计了一种包含信仰、能力、行为队列,行为调度、消息邮箱五元组的实用结构模型,并探讨了多Agent的通信和协作。在此基础上给出了一种基于多Agent中间件JADE的预知维护实现参考模型,利用该模型建立了一个水轮机调速系统液压伺服机构的多Agent维护原型系统,验证了模型的合理性和可操作性。 A hierarchical distributed multi-Agent model of hydropower plant predictive maintenance based on multi-Agent theory is proposed,which consists of four layers:data acquisition,data processing,diagnosis prognosis and maintenance decision-making.A practical structural model is designed for the maintenance Agent,including five elements:belief,capability,behavior queue,behavior dispatch,and message box.The communication among multiple Agents and their cooperation are discussed.An implementation reference model based on multi-Agent middleware JADE is proposed,with which,a prototype of multi-Agent maintenance system for the electro-hydraulic servomechanism of water turbine governing system is established.Its rationality and feasibility are verified.
