面向对象技术在直接数字控制系统中的应用

研究直接数字控制系统中的面向对象技术，开发典型的直接数字控制系统－工控ＰＣ核子秤计量与监控系统。采用面向对象的３层模式结构和面向对象程序设计方法对系统模块进行设计与开发，例如系统配置，实时控制等。克服了面向过程方法设计系统的通用性、灵活性和维护性差的问题，从而使系统具有广阔的应用前景。

Applications of Object-Oriented Technology in Direct Digital Control Systems

The object oriented technology in direct digital control systems was studied. A direct digital control system that is industrial nucleon balance measurement and monitor system was designed and developed. Three level modul structure was built, and object oriented programming method was adopted in all of the submodules, such as system configuration, real time control, and so on. The disadvantages in the generality, flexibility, and maintainability of process oriented programming were overcomed. The application prospect of the system was good.
