　　燕山石化公司合成橡胶凝聚装置的仪表控制系统原由常规仪表构成，且全是其他装置更换下来的旧表，故障率较高。为了提高自动化水平，增强仪表控制系统的可靠性，我们对其进行了改造，淘汰了控制室内的所有常规仪表，改用DCS。
　浙大中控公司的SUPCON JX-300X DCS充分利用了最新信号处理技术、高速网络通信技术、可靠成熟的先进控制算法，使其兼具了高速可靠的数据输入输出运算、过程控制和PLC联锁逻辑控制功能，获得了广泛的应用，特别是其性能价格比优于同等规模的常规仪表系统，成了我们仪表改造首选的产品。
　　二 工艺流程简介
　　凝聚装置采用水蒸气蒸馏、湿法脱气的原理，脱去胶液中的溶剂油。现有两条生产线，每条线包括胶罐系统、凝聚釜系统、尾气回收系统。每条生产线有4个胶罐，根据胶液熔融指数的不同，不同胶罐中的胶液按相应的比例混配，保证胶液熔融指数合格。合格的胶液送至凝聚釜，根据水蒸气蒸馏、湿法脱气的原理，采用等压不等温的双釜水析凝聚技术，把溶剂油和胶分离。凝聚釜分离出来的溶剂油尾气由尾气回收系统回收再利用。
　　三 DCS配置
　　JX-300X DCS由一个多功能站、一个操作站、一个控制站和过程控制网络组成，系统结构如图1。
护工具。操作站是操作人员完成生产过程监控管理任务的平台。
　　多功能站和操作站的硬件组成是完全一样的，包括工控PC机、CRT、鼠标、键盘、网卡、专用操作员键盘、操作台等。
　　控制站完成整个工业过程的实时监控功能，由主控制卡、数据转发卡、I/O卡件、供电单元等组成。控制站的各种卡件均可冗余配置，为了增加系统的可靠性，我们对控制站的主控制卡、数据转发卡进行了冗余配置，控制回路的I/O卡件也采用冗余配置。表1列出了控制站的硬件，表2为系统的I/O信号及卡件配备表。
