【摘要】：铁矿选矿生产过程中,球磨机的磨矿是选矿生产过程中的关键环节,球磨机运行的控制水平直接影响选矿的产量、能耗与效益。当前大多数选矿过程没有实现磨机负荷自动控制与信息化,磨机产量不能最大程度的得以提升。因此,需要开发一种中小选矿厂选矿自动化与信息化相结合的系统。通过设计专用磨机控制仪实现磨矿自动化,使工程具有了产品化的特点。磨机控制仪采用ARM单片机,具有料、水、磨音、磨机电流的测量与控制功能。利用单片机使用高级语言能够实现复杂算法的特点,使产品更具智能化。由于磨矿过程的磨机负荷具有非线性、大滞后、时变性的特点,引用了磨机特性线性化处理与专家控制相结合的方法,取得了理想的控制效果。研究了磨矿自动化与信息化的系统集成技术,介绍了自动化与信息化通讯的数据协议、数据库的数据结构、C#实现客户端软件设计的实现技术、报表模块设计以及能耗成本与效益分析模块设计。建立了对象实验模型,进行了系统的仿真运行。结果表明,软件实现了选矿自动化与信息化的目的,控制效果良好。实现了工程产品化、产品智能化、系统网络化的思想,实现了以智能制造为核心的信息化技术思路。
[Abstract]:In the process of ore dressing, the grinding of ball mill is the key link in the process of ore dressing, and the control level of ball mill operation directly affects the production of ore dressing. Energy consumption and efficiency. At present, most mineral processing processes do not realize the automatic control and information of mill load, and the mill output can not be maximized. It is necessary to develop a system of mineral processing automation and informatization in medium and small concentrators. The grinding automation is realized by designing a special mill control instrument, which makes the project have the characteristics of production. The mill control instrument adopts ARM single chip computer, has material and water, The features of complex algorithm can be realized by using single-chip microcomputer, and the products are more intelligent. Because the mill load of grinding process has the characteristics of nonlinear, large lag and time-varying, it can be used to measure and control the current of grinding machine. The method of combining the characteristic linearization of mill with expert control is introduced, and the ideal control effect is obtained. The system integration technology of grinding automation and informatization is studied, and the data protocol between automation and information communication is introduced. The data structure of database C # realizes the technology of client software design, report module design and energy consumption cost and benefit analysis module design. The object experiment model is established, and the system simulation is carried out. The results show that, The software realizes the aim of mineral processing automation and informatization, the control effect is good, the idea of engineering production, product intelligence, system network is realized, and the information technology thinking with intelligent manufacturing as the core is realized.
