摘　　要：构建了车间层分布式数字控制系统信息交互平台体系结构,该平台融合了设备层信息与车间层控制、管理信息,可实现底层设备与上层应用系统之间的信息交换与融合集成。提出了基于多智能体的分布式数字控制系统信息集成框架,建立了网络结构及通信机制;论述了多智能体在此集成框架下实现分布式数字控制系统基于总线的设备集成控制,以及与企业内部系统基于公共对象请求代理体系结构的信息集成和与外部系统基于Web服务的信息集成;对其中多智能体、可扩展标记语言消息封装、Web服务等关键技术进行了探讨。阐释了该平台的实现及应用,验证了其可行性。Architecture of information interaction platform for Distributed Numerical Control （DNC） system of networked manufacturing in the workshop level was established. This platform integrated the information of the equipment level and the workshop applications level so as to realize integration and information interactions between shopfloor equipment and top-level application systems. An information integration framework of this platform based on Multi-Agent System（MAS） and Common Object Request Broker Architecture （CORBA） was proposed. Network structure and communication mechanism were constructed. Method using DNC system in this framework to meet the equipment level integration control and integrate information within enterprise and external systems was discussed. Key technologies, such as Agent, eXtensible Markup Language （XML） and Web services, were discussed. Finally, the realization and applications of this platform were introduced and its feasibility was proved.
