现场总线仪表由于其全数字性、精度高、抗干扰能力强、高速通信、内嵌控制功能、系统综合成本低等特点被大量应用于现代工业中,但在不同的工业流程及现场环境下如何可靠运行是众多使用者关注的重要问题。介绍酒泉钢铁(集团)有限责任公司碳钢薄板厂炼钢转炉现场总线仪表的应用情况,对该系统在运行维护中发现存在的异构网络结构、接地、总线短路等问题进行了分析并提出相应的解决措施。
Because of its all-digital nature, high accuracy, strong anti-interference ability, high-speed communication, embedded control function and low overall system cost, field bus instruments are widely used in modern industry. However, under different industrial processes and on-site environment Reliable operation is an important issue that many users are concerned about. This article introduces the application situation of the steel converter field bus instrument in the carbon steel sheet factory of Jiuquan Iron and Steel (Group) Co., Ltd., and analyzes the problems of the heterogeneous network structure, grounding and bus short circuit found in the operation and maintenance of the system, The solution.
