中文摘要:
      LNG燃气站作为天然气输配系统的重要工业场所,保障其安全运行、降低安全隐患等问题变得尤为重要。以液化气站实际工程项目为背景,为了提高中小型LNG燃气站控制系统的安全性能,降低生产成本,设计一套基于FIX组态软件及SHCAN现场总线的智能监控系统方案,实现人机交互界面,完成实时数据采集显示、远程监控控制、数据记载,报警等功能,满足LNG燃气站生产监控需求。测试结果表明,可在300 ms内刷新完成数据的实时显示,记录数年的历史数据,实现报警管理,并于2017年1月在辽宁营口大石桥青花集团实际投入使用至今,运行效果证明了该监控系统的设计方案正确有效。
英文摘要:
      As an important industrial site of natural gas transmission and distribution system, it has become particularly important for LNG gas station to ensure safe operation and reduce potential safety hazards. The article takes the actual project of a liquefied gas station as the background. In order to improve the safety performance of small and medium-sized LNG gas station control system, a cost-effective intelligent monitoring system was designed. It implements a human-computer interaction interface and real-time data acquisition monitoring alarming and interlocking functions in order to meet the production monitoring needs of LNG gas stations based on FIX configuration software and SHCAN fieldbus. The system test results show that the real-time display of the completed data can be refreshed within 300 ms, several years’historical data can be recorded and it can realize alarm management. The operation results that the monitoring system designed by this project is correct and effective.
