基于基金会现场总线的测控实验系统设计

Design of Measuring Control Lab System Based on Foundation Fieldbus

描述了现场总线的发展前景,设计了一套基于基金会现场总线技术的测控实验系统,并且详细描述了系统控制对象的选取、硬件的构成以及系统的应用。该系统不但可以实现单回路控制,还可以完成串级、比值等复杂控制方案。该系统具有很好的可扩性,在其基础上,利用PLC、DSC等先进控制装置也可完成各种控制方案设计。

The development foreground of fieldbus is described. A suit of measuring control system based on foundation fieldbus technology is designed, and the choice of system control object, the structure of hardware and the implementation of this system are illustrated. This system can not only finish single loop control, but also can implement complex control schemes such as cascade and ratio etc. This system has good expansibility, based on this system, kinds of control schemes can be designed by using advanced control equipments such as PLC, DCS etc.
