摘　　要： 随着选矿技术的不断发展,选矿过程控制软件也在飞速的更新换代以跟上选矿技术前进的步伐。由于选矿生产过程的差异性和复杂性,导致选矿过程控制系统软件存在着一些缺陷,如研发周期长,程序可复用性差,程序维护、升级、移植困难等问题。 模块化设计是在对一定范围内的不同功能或相同功能不同性能、不同规格的产品进行功能分析的基础上,划分并设计出一系列功能模块,通过模块的选择和组合构成不同类别的产品,以满足市场的不同需求。本文创新性地把模块化方法应用在选矿过程控制系统软件的设计中,开发出了满足选矿工艺要求的功能模块,解决了传统控制系统软件中存在的问题。接着利用这些模块,设计开发了镜铁山铜选厂控制系统软件,克服了工期短,任务紧,设备多,流程长,控制模式复杂等困难,提前完成项目的开发工作。经过现场试车表明,控制系统运行正常,实现了设计功能,保证铜选生产过程的稳定运行,满足现场的控制要求,保证生产安全,取得了良好的实际效果。本文主要完成了下面几个方面的工作： 1.在分析了选矿生产过程控制系统软件的问题和模块化设计方法的优点之后,得出模块化设计可以解决控制系统软件设计中存在的问题的结论,创新性地提出了把模块化设计思想应用到选矿生产过程控制系统软件开发过程中的思路,同时结合选矿生产过程,提出了模块化设计的具体步骤。 2.按照模块化设计步骤,设计了选矿生产过程控制系统软件的功能模块。在深入研究分析控制系统软件的基础上,按照功能划分出不同类别的功能模块,比如系统监视功能模块,数据采集功能模块,设备程序功能模块,结构化PID模块,第三方通讯模块等等,同时基于西门子S7-300,设计了PLC冗余系统；设计了不同模块间通讯方式。 3.开发了控制系统的不� With the ore-dressing production technology continues to evolve, ore-dressing production process computer control system is also rapid upgrading to keep up with the pace of progress by the Ore-dressing Technology. Due to the differences and complexity of ore-dressing processes, some problems lead to the ore-dressing production process computer control system software. For example, the R/&D cycle is long, the program reusability is poor, and program maintains, upgrades, transplants difficulty. Modular design are built on the basis of function analysis of a certain range of products within which have different functions or the same function, different performance,different specifications. Modular design divides and designs a series of functional modules, then, constitutes the different categories of products through the selection and combination of modules in order to meet market demand. In this article, innovative, modular approaches are used in the design of the production process computer control system software. This thesis develops the functional modules to meet the requirements of beneficiation process, also solves the existing problems in the conventional control system software. After that, using of these modules, this thesis designs and develops JingTie Mountain computer control system software, overcomes many difficulties and completes the of the project development work. Through the field test showed that the control system is operating normally and achieving designed function. Ensuring the copper choose the stable operation of the production process. Meeting the site control needs. In this thesis, completed the following work: 1. After analysis of the advantages of the ore-dressing production process computer control system software and modular design method, this thesis comes to the conclusion that modular design can solve the control system software problems, putting forward innovative idea of combining the modular design and control system software. Besides, we put forward modular design steps.
