介绍了一种精炼加料系统中的控制方案。从软、硬件两方面阐述了系统的组成和功能,对加料的方法进行了介绍。系统以昆腾PLC为控制核心,使用Concept V2.2 XL组态软件,在保证现场设备按要求稳定运行的基础上,完成了数据的分析和处理。同时结合变频技术,实现了下料、计量及物料精度的稳定控制。用户也可以根据需要灵活调整频率。从技术概述、系统特点、软硬件配置及程序设计等几个方面对系统展开论述,并给出部分程序。
A control scheme in a refinery feeding system is introduced. From the aspects of software and hardware, the composition and function of the system are expounded, and the method of adding material is introduced. System to Quantum PLC as the control center, the use of Concept V2.2 XL configuration software, on the basis of ensuring the stable operation of on-site equipment required, completed the data analysis and processing. At the same time with the frequency conversion technology, to achieve the material, measurement and material stability control. Users can also adjust the frequency as needed. From the technical overview, system features, hardware and software configuration and program design and other aspects of the system to start the discussion, and gives part of the program.
