摘　　要：本文提出基于知识的健康管理系统结构,实现对对象的健康管理.通过对象领域知识的本体建模,实现领域知识的共享、重用.建立健康管理领域知识相关推理规则,通过推理机实现对健康管理领域任务的推理.依据推理结果,组成具备相关功能的主体,通过多主体协作,实现健康管理任务.本文提出通过主体投票实现数据融合,提高诊断准确性与可靠性.以螺钉松动诊断监测过程说明系统工作过程与效能.For the health management of complex system,a knowledge based health management system design is proposed in this paper.Through the ontology modeling of the domain knowledge,the sharing and reuse of the knowledge can be achieved.Building the related reasoning rules and with the help of reasoner,domain knowledge involved in health management can be inferred.With this knowledge,the related functional agent can be organized in to a multi agent system to achieve the health management task.A strategy of voting mechanism is proposed in data fusion,to improve the veracity and reliability of diagnosis.A system of bolt loosening health management system is showed to verify the system and it＇s efficiency.
