Abstract

The next generation of factory control systems will consist of a conglomeration of hardware and software resources that must work together to achieve factory-wide targets of throughput, quality and reconfigurablity. The University of Michigan's Engineering Research Center has developed a control system that extends reconfigurable software event-based control by considering a manufacturing system as a set of decentralized resources of both hardware and software instead of separate solutions for hardware/logic and software control. This software control system utilizes the event-condition-action (ECA) paradigm to realize event based control, with workflow "rules" stored in a relational database. We facilitate the control workflow management through a graphical front end tool that uses simple forms and a flowchart-like display to represent complex rules. It allows a user with little technical know-how to view, create and maintain control rules of the software system. This graphical tool operates independently of the system being controlled, by manipulating the workflow rules in the database; thereby enabling control strategies to be updated in real time

一个“控制工作流管理”HMI配置和维护一个基于事件的控制系统

下一代工厂控制系统将由硬件和软件资源的集合体组成，它们必须协同工作，以实现工厂范围内的吞吐量、质量和可重构性目标。密歇根大学工程研究中心开发了一种控制系统，通过将制造系统视为一组分散的硬件和软件资源，而不是硬件/逻辑和软件控制的独立解决方案，该系统扩展了可重构软件基于事件的控制。该软件控制系统采用事件-条件-动作(ECA)模式实现基于事件的控制，并将工作流“规则”存储在关系数据库中。我们通过图形化前端工具简化控制工作流管理，该工具使用简单的表单和类似流程图的显示来表示复杂的规则。它允许几乎没有技术知识的用户查看、创建和维护软件系统的控制规则。该图形工具通过操纵数据库中的工作流规则，独立于被控制的系统运行;从而使控制策略能够实时更新
