摘 要 随着计算机技术的发展以及工业自动化水平的不断提高，利用计算机技术对生产进行管理以及对生产过程实施数据采集和监控，越来越受到人们的关注。 无缝钢管行业对于一个国家的经济发展具有重要意义。当今世界，无缝钢管生产线种类繁多，竞争激烈，只有提升和革新新技术，才能获得发展。本文主要介绍了相关课题背景和国内外无缝钢管行业的发展现状，以及涉及无缝钢管生产线监控系统设计的工业以太网技术、Profibus-DP现场总线技术以及WinCC组态软件技术等。本设计以西门子新一代过程控制系统WinCC为软件平台，重点论述基于 SIMATIC WINCC 的无缝钢管生产过程计算机监控系统的开发,简述WINCC的 OPC 通讯功能。在分析了技术要求和用户需求后，设计开发了无缝钢管生产过程计算机监控系统和逻辑控制程序。 关键字：无缝钢管；WinCC；工业以太网；Profibus-DP；PLC Abstract With the development of computer technology and industrial automation, more and more attention has been paid to the management of production and the data collection and monitor in the production process by computer technology. The industry of seamless steel tube is significant to the development of the national economy. Nowadays, there are many types of seamless steel tube production line in the world, and much fierce competition between them. Only by upgrading and developing technologies can it be survived and developed. This article mainly describes the current development status of seamless steel and related background. Industrial Ethernet technology, Profibus-DP technology and WinCC configuration software technology about the design of seamless steel tube production line monitoring system are also involved. The design is based on Siemens’ new generation of process control system software platform, and focuses on the development of computer monitoring system of seamless steel tube production line and the WinCC OPC communication. After analyzing the technical requirements and users’ needs, I design and develop the manufacturing process control systems and computer logic control procedures of the seamless steel tube production.
