基于现场总线的数字式电液执行机构的开发

Development of Digital Electro-hydraulic Actuator Based on Fieldbus

近年来,过程控制系统迅速从分散型控制系统向现场总线控制系统发展,智能仪表将取代模拟代表。介绍了现场总线的特点和发展现状以及基于现场总线的数字式电液执行机构开发。

In recent years,process control has developed rapidly from DCS to FCS (fieldbus control system).Intelligent instrument will replace analog instrument correspondingly.The development of FCS and the advantage of digital electrohydraulic actuator based on fieldbus are well known.
