现场总线技术在防洪堤坝监控中的应用,是目前最先进的监控模式。本文介绍了在现场总线下的堤防大坝安全监控系统,在该系统中使用工控组太软件构成软件操作平台,使用Allen-Bradley的Logix5550控制器作为控制主体,其它一系列设备作为辅助,构成整个预警系统,同时阐述了大坝安全监控系统在现场总线下的设计思想和方法。 Field bus technology in the flood control dam monitoring application, is the most advanced monitoring mode. This paper introduces the dyke dam safety monitoring system under the field bus. In this system, it uses too much software of the industrial control group to form the software operating platform. Using the Allen-Bradley Logix5550 controller as the control body, a series of other devices serve as auxiliary to form the whole Early warning system, at the same time describes the dam safety monitoring system in the fieldbus design ideas and methods.
