碱回收燃烧工段DCS控制系统设计 摘 要 燃烧是造纸过程的一个重要环节，旧的燃烧工段存在许多的缺点。本设计是利用DCS系统对造纸过程中碱回收燃烧工段进行控制。工业实时监控系统是目前研究的热点问题之一，其中生产数据采集的方法和生产数据发布系统的稳定性和高效性更是研究的重点。在该系统中采用西门子的S7300系列CPU模块内置的MPI 接口，PLC来对燃烧工段进行控制，并用WinCC5.0来组态一个HMI平台，对该控制系统进行监控。 WinCC是一个功能强大的全面开放的监控系统，既可以用来完成小规模的简单过程监控，也可以用来完成复杂的应用。本文详细介绍了如何构建一个高效的基于WinCC软件的工业实时监控系统，本设计运用WinCC组态软件制作出了碱回收燃烧工段的上位机监控画面，通过控制画面可对碱回收燃烧工段的设备进行控制。本设计体现出WinCC软件的多种自动化设备及控制软件集成，具有丰富的设置项目、可视窗口和菜单选项，使用方式灵活，功能齐全。在控制画面中还可以看见趋势曲线等，通过趋势曲线可了解工厂的生产状况，为操作者提供了直观的操作环境。不仅了解了工厂生产线状态，而且提高了工作效率。WinCC能够用于多种用途的控制系统，同时提供嵌入式C语言编程，用户可以通过编辑项目函数和行为来实现特殊的功能。 关键词:HMI，燃烧，WinCC，DCS The Design of DCS Control System on Alkali Recovery Combustion Workshop Section ABSTRACT The combustion is an important link of the deckle process, the old burnable work segment exists much weakness.This design is to make use of the DCS system to carry on a control to the alkali recovery combustion work segment in the deckle process，Supervised and control system when industry was solid heat be currently to study to order one of the problems，Produce the method and the production data that the data collect to release the stability of the system among them and efficiently is also the point of the research.Adopt the S7300 series CPU mold piece of Siemens in that system to connect inside the MPI place，The PLC comes to the work segment to carry on a control to the combustionCounteract Wincc5.0 come to set HMI terrace， carry on supervision to that control system. The WinCC is a function strong overall liberal supervision system,since can use to the simple process supervision of complete the small scale,also can use to complete a complicated application.This design make use of WinCC software work alkali the recovery burn the work segment of the place of honor machine control appearance,The equipments that control appearance and cans recover the burnable work segment to the alkali carries on a control.The body appears various automation equipmentses and the control software integration of the WinCC software，Have
