关于开放型集散式控制系统软件设计的讨论

ON THE DESIGN OF OPEN DCS SOFTWARE

按照传统的设计方法,一个集散式控制系统与硬件环境是紧密相关的。设计一个集散式控制系统,首先应考虑它的硬件环境设置,而它的软件系统设计则是在硬件环境的基础上进行的。随着面向对象技术的引入,面向对象集散式控制系统的软件设计已不必完全依赖于硬件的环境了,它的软件设计完全可以超前于硬件环境的设计,因为我们可以根据软件设计所提供的不同的基本控制元类来组装成硬件环境中提出的各种不同的控制要求。在本文中,以一个机动车自动检测控制系统的模型,来讨论如何利用面向对象技术设计一个易维护,易组合与拆卸的开放型集散式控制系统。

As the traditional design method, the DOS ia close to the hardware environment, the DCS design have to think its hardware environment installation over because its software system design, is environment on the basis of hardware. With leading into O-O technology, OODCS software design have to be dependent on hardware environment net at all. Its design is completely before the design of hardware environment. In this paper, as the veLicle automatic check control system me del, we discuss how to design the Open DCS of eaay maintenance, esay combination and dismount by 0-0 technology.
