面向对象的程序设计方法在输送系统中的应用

Application of Object Facing Programming at Transportation System

本文阐述了面向对象技术的编程方法在基于PLC控制系统中的应用,并以一个输送系统为例介绍了系统中类的抽象、封装和继承之间的相互关系。面向对象的程序设计方法相比于传统的线性化编程方法具有使程序更加简练,更加模块化,易于理解并且能大大提高系统的可扩展性,是大型输送系统编程的理想设计方法。

In this article, application of object facing programming at control system based on PIE has been introduced. Taking the example of one transportation system, relationship among genus abstract, encapsulation and inheritage of system. In comparison to conventional linear programming, object facing programming Methods makes program more concise and modularization, easy to understand, in addition, it can improve system extensibility, is the ideal design method for large scale transportation system programming.
