70年代中期以来,为适应现代工业综合自动化和全盘自动化的要求,采用微电子技术、计算技术、通讯技术、光技术和大系统控制理论等,使过程控制装置及系统在技术结构、产品结构和工艺结构等方面发生了重大变革,出现了多层次的系统结构,以满足各种不同的要求。这里要介绍的是西仪横河控制系统有限公司引进日本横河公司的YEWPACK MARKⅡ控制系统。 YEWPACK MARKⅡ是一种用于几个回路到近百个回路的适合于中小规模的标准成套化仪表控制系统。具有能满足各种要求的控制功能及采用彩色图象显示的多功能人机联系方式,为此能够适应从连续控制至复杂的分批、广泛的控制要求。
Since the mid-1970s, in order to meet the requirements of modern industrial automation and overall automation, micro-electronic technology, computing technology, communication technology, optical technology and large-system control theory have been applied to make process control devices and systems in the fields of technology structure, product structure and Process structure and so has undergone major changes, there has been a multi-level system structure to meet different requirements. Here to introduce the West Yokogawa Control System Co., Ltd. introduced Yokogawa Japan’s YEWPACK MARK Ⅱ control system. YEWPACK MARK Ⅱ is a standard control system for small and medium-sized instruments used in several circuits to nearly one hundred circuits. Has to meet the various requirements of the control functions and the use of color image display multi-function man-machine contact information, to be able to adapt from continuous control to complex batch, a wide range of control requirements.
