本文以铸造制壳线控制系统为例,介绍了一种离散式控制系统的设计方法。采用先进的控制技术及网络技术,根据控制系统不同的功能,单独设计并就近控制,各子系统通过网络与主控系统进行互联,最终形成一个完整的控制系统。这种设计思路,有助于对单个的系统进行性能的优化和升级,并最小程度的减少了对其他系统的影响。本文重点介绍了该控制系统的构成,硬件配置及控制原理等内容。
In this paper, casting shell line control system, for example, introduced a discrete control system design. The use of advanced control technology and network technology, according to the different functions of the control system, separate design and close to the control, the various subsystems interconnected with the main control system through the network, and ultimately form a complete control system. This design idea helps to optimize and upgrade the performance of individual systems with minimal impact on other systems. This article focuses on the composition of the control system, hardware configuration and control principles and so on.
