日期：2021-5-104 dcs的工程实现
由dcs的结构可知其工程实现是不困难的，国外早有现成产品，国内一些大型企业如电厂等几乎都是进口的成套系统，可靠性高，但投资大。一般可以自己设计，现场控制级可以采用工控机保证高可靠性，管理决策级采用高档pc机，应用软件可根据工程需要自己编程。特别是一些复杂控制对象，其控制算法是没有现成控制模块可以调用的，应在正确策略选取的基础上，自己设计控制算法。从作者已完成的多个工程项目看，采用dcs系统克服“孤岛”现象后，每个“自动化孤岛”在决策级统一指挥下协调地工作，系统的管理（监视）功能大大增强，现场控制级处于优化状态，生产效率高，故障少，产品质量稳定，操作管理人员也相应减少了，经济效益显著提高。如某钢铁企业有12个自动化水泵站，由于地域分散，泵站间距离有的相距1km以上，各泵站各自为政，形如“孤岛”，计划调度十分不便，本来水资源供应十分充足，但由于是分散控制，造成有的现场严重缺水。经改造后采用dcs控制方案，很好地解决了水资源的集中调度与管理问题，不仅充分满足了该企业的工作及生活用水，而且还解决了周边地区居民用水问题，经济效益和社会效益大大提高，管理水平也上了一个新台阶，受到用户欢迎。
5 结束语
从图3可见，各控制单元之间没有直接通信联系，它们之间是通过决策单元交换信息取得联系的，事实上dcs只是做到了半分布，测控层并没有实现彻底分布，控制依赖于控制站，dcs是半数字化系统。如采用现场总线，则可构成现场总线控制系统（fcs），它是一种全数字、半双工串行双向通讯系统，作为一种局域网，用于连接现场智能仪表，其信号传输采用全数字化，即智能式分布控制系统。智能式分布控制系统在国外已有现成产品，如lonworks等，但因价格太贵，要普遍大规模推广应用还有不少困难。因此，推广应用dcs系统，克服“孤岛”现象，是有现实工程价值和经济意义的。
