20世纪90年代,走向实用化的现场总线控制系统(Fieldbus Control System,简称FCS)获得了迅猛发展,成为世界上最新型的控制系统之一。现场总线促使传统控制系统结构发生变革,形成了新型的网络集成式全分布控制系统——FCS。虽然各国都在研究FCS的应用,在一些领域中也取得了成果,但到目前为止,FCS的国际标准尚未最后完成,无论在学术研究或是工程应用方面,都有必要使FCS综合继承集散控制系统 (Distributed Control System,简称DCS)的成熟策略,并充分研究新型的智能测控电路、工业控制系统的智能设备等与现场总线完美集成的方式, 以实现DCS向FCS的平滑过渡。
In the 1990s, the fieldbus control system (Fieldbus Control System, referred to as FCS for short) was gaining momentum and became one of the newest control systems in the world. Fieldbus to promote the traditional control system structure changes, formed a new type of network-based integrated distributed control system - FCS. Although all countries are studying the application of FCS and have made some achievements in some fields, so far, the international standards of FCS have not yet been finalized, so it is necessary for FCS to inherit distributed control in both academic research and engineering application (Distributed Control System, referred to as DCS) mature strategy, and fully study the new intelligent measurement and control circuits, industrial control systems and smart devices and other fieldbus integrated with the perfect way to achieve a smooth transition from DCS to FCS.
