【摘要】 讨论了在过程工业监测系统中行为定制机制的实现。通过行为定制机制,过程工业监测系统的用户可以为系统中的数据流事件、操作事件和定时事件定制响应行为脚本,在监测系统的固有功能之上自主地加入自己的数据处理功能。行为定制实现的基础是脚本技术和组件对象技术。行为定制机制要求监测系统为用户提供一组组件对象,用户可以在行为脚本中通过访问这些组件对象来访问生产数据,也可以在行为脚本中创建和使用其他应用系统提供的组件对象,获得其他应用系统的功能支持。更多还原

【Abstract】 The implementation of the custom action mechanism in the process industry monitoring system is discussed.With the help of the custom action mechanism,user of the process industry monitoring system could design response action scripts for data flow events,operation events and timer events of the system.By these scripts,the user could append one′s own data process functions into the monitoring system. basle technology of the custom action is script technology and component object technology.The custom action mechanism requires that the monitoring system provide a set of component objects to the user.Users could visit the system data by using these component objects.Users al- so could obtain other applications′functions by creating and using the component objects provided by these applications.更多还原
