远程智能I/O及其在过程工业的应用

Remote Intelligent I/O and Application in Process Industry

本文介绍了过程Ｉ／Ｏ装置的发展历史和演变过程，指出了使用平行共地总线插板Ｉ／Ｏ构成的计算机系统（ＤＡＳ、ＤＣＳ）用于过程工业存在的主要问题和使用远程智能Ｉ／Ｏ构成的工业计算机监控系统及生产自动化管理信息系统（ＭＩＳ）具有的若干优点，重点阐述了远程智能Ｉ／Ｏ的设计思想和一般结构与工作原理以及在过程工业的若干应用，最后对远程智能Ｉ／Ｏ的发展提出了几点看法。

： The development history of the process I/O in the industrial computer systems is introduced and the important weakness of a system using the I/O modules in the model of plug-in plates and the advantages of the system(DAS.DCS or MIS) adopting the remote intelligent I/O are pointed out in this paper. Especially the design thinking and operation principle are emphasized. Finally, several viewpoints on the developing retnote intelligence I/O are also put forward.
