集散控制系统（Distributed Control System－DCS）集计算机技术、控制技术、通信技术、CRT技术于一体，广泛应用于生产过程控制系统。随着计算机和网络技术的飞速发展，产生了一种新型的控制系统———现场总线控制系统（Fieldbus Control System－FCS）。但国内生产企业的情况是：大多数企业还处于模拟仪表和人工控制的阶段，采用DCS控制系统的企业仍是少数。由于DCS应用广泛、技术成熟，在现有的技术条件和市场条件下，FCS还不能完全取代DCS，而且目前现场总线设备和系统还十分昂贵。因此，除了新建企业外，国内企业在较长时间不可能全面采用现场总线技术，而必须走逐步发展、过渡的道路。 ??我们在上海石化股份公司环保部水质净化厂监控系统的改造项目中，对3个生产单元已有的DCS和PLC进行改造，增加通信功能，实现总调度室对各生产装置的集中监控。 2?系统改造方案?? 根据水质净化厂各生产单元的功能和建设阶段，分为厂外调节池、污水一段、氧化沟、四期污水处理、污泥脱水、污泥干化6个生产单元。另外，在厂部设有总调度室，但是总调度室的监控水平较为落后，改造之前基本上不能对各个生产单元进行监控。为了适应生产需要，提高生产效率，改善操作条件，加强监控手段，确保各生产装置的正常运行，急需对各生产单元和总调度室进行技术和设备的更新改造，从而能在总调度室对各装置进行监视管理，及时了解各装置的运行情况，达到指挥及时和调度准确的目的。 2．1?现场监控系统的改造 ??现场监控系统的改造要充分利用原有仪表和设备，主要考虑可靠性和实时性。首先对自控程度较高的3个单元进行改造（系统结构见图2—1）： ??四期污水处理生产单元控制设备配置了两套ALLEN－BRADELY公司PLC设备。25块开关量输入信号卡，可采集384点信号；7块开关量输出信号卡，可输出112点信号；3块模拟量输入信号卡，可采集24点信号。两套AB—PLC通过DH＋（数据高速通道）实现数据共享。在原有的现场控制计算机上分别增加以太网卡，通过以太网将实时数据送到总调度室处理。??输出192点信号；1块模拟量输入信号卡，可采集8点信号。系统运行采用遥控开关操作与全模拟流程盘显示。在原有的Siemens S5－115UPLC上增加RS－232通讯模块（CP524）和1台现场操作站，用点对点方法连接，使PLC的数据通过现场操作站送到以太网上，与总调度室监控计算机通信。但RS－232传输速率只有9600bps，操作站仅对现场起到监视作用。
