本文论述了网络化个人计算机与SCADA系统集成的必要性和方法。基于一些正在进行的过程控制和SCADA项目，从行业范围的角度讨论了个人计算机在在线水处理中的创造性使用。作者首先确定了各种实用程序中的信息处理需求，从资源调度到预测模型。关于使用PC设计和构建集成系统的详细讨论包括非实时系统、实时系统、信息系统互连和网络规模调整。

This paper addresses the need for and approach taken for the integration of networked personal computers with SCADA systems. Creative uses of personal computers in on-line water operations are addressed from an industry-wide perspective based on a number of on-going process control and SCADA projects. The author first identifies information processing needs in various utilities, from resource scheduling to predictive models. A detailed discussion of designing and building integrated systems with PCs encompasses non real-time systems, real-time systems, and interconnecting the information systems and sizing the network.
