粘胶纤维生产过程多通道实时监控及查询分析系统

Multi-channel Real-time Moniter and Data Query-analysis System in Pectic Fibre Production

为解决粘胶纤维酸浴过程调配酸浴的品质不高,酸浴质量浓度波动较大,无法及时检测、分析生产过程中酸浴的变化情况等问题,采用西门子S7—200 PLC和Visual Basic net,开发了多通道实时监控系统。系统对历史数据采用SQL Server数据库进行保存,可方便地进行在线查询、分析;酸浴实时监控系统配置灵活,扩充方便,可靠性高;上位机监控软件使用便捷,对实时和历史数据能够以直观形象的形式表现,查询、分析、打印功能灵活。

Siemens S7- 200 PLC and visual Basic net are adopted to develop the multi-channel real-time monitor system for the purpose of solving the probelm about the low quality of acid bath procedure reglulation of pectic fibre, big fluctuation of acid density and unability to detect and analyze the variation of acid bath in time. The system adopts SQL server database to storage the original data so as to make it easy to do on-line inquiry and analysis; The real-time monitor system of acid bath has a flexible configuration, extensibility and high reliability. The upper monitoring software can be easily applied, can visually represent the real-time data and original data, and has a flexible function of quiery analysis and printing.
