【摘要】：在进行选煤厂设计或者老厂改造时,设备选型是一项至关重要的工作。选择合适的设备不仅能提高生产效率、优化厂房布置,而且能节省资金,避免给国家或企业造成不必要的浪费。由于选煤设备的复杂性和独特性,造成选煤设备选型计算时涉及到的因素较多,需要考虑的条件繁琐。如果能够利用计算机来完成这些选型工作,将会使选型效率及准确性大大提高。本文借助专家知识库、设备数据库,选型方法库等,将选型理论知识和设备选型思想结合在一起,以实现选煤设备的初级智能选型。本文根据设备在选煤生产过程中的不同用途将选煤设备分为八个类别:筛分机械、破碎机械、分选机械、脱水机械、运输机械、给料和准备机械、泵和其他设备。通过对不同的设备类型进行选型指标的系统分析,选定了工艺技术指标、经济性、可靠性、厂商信息、节能环保5个主要评价指标建立基于层次分析法的设备选型专家系统评价体系。以调查问卷的形式咨询行业专家以及一线生产工人,统计各个评价指标的权重系数,通过矩阵计算得到某个设备选型指标的按权重排序的列表,以供选煤设计人员、选煤厂领导等进行参考决策。针对选煤设备图库的功能需求分析,结合设备选型的评价指标体系,建立了选煤设备初级智能化选型系统。系统使用SQL Server构建数据库、IIS作为服务器端运行环境,运用.NET技术,实现了基于Internet的B/S结构模式应用软件系统的核心部分的开发。系统主要包括选煤设备图库管理、选煤设备厂家管理、选煤设备选型管理和选煤设备综合展示平台四个主要核心功能。最后,针对选煤厂计算机辅助设计软件(CPCAD)单机系统进行了网络化研究。结合开发的选煤设备选型系统对CPCAD的设备图库进行手动、定时更新。规划借助过程控制与模拟优化研究所开发的自动化办公平台中的工作流管理模块来实现CPCAD的网络化协同办公。
[Abstract]:In the design of coal preparation plant or the renovation of the old plant, the selection of equipment is a very important task. Choosing suitable equipment can not only improve production efficiency, optimize plant layout, but also save money and avoid unnecessary waste to country or enterprise. Because of the complexity and uniqueness of the coal preparation equipment, there are many factors involved in the selection and calculation of the coal preparation equipment, and the conditions to be considered are tedious. If the computer can be used to complete the selection, the efficiency and accuracy of the selection will be greatly improved. In this paper, with the help of expert knowledge base, equipment database, selection method database and so on, the selection theory knowledge and the equipment selection idea are combined to realize the primary intelligent selection of coal preparation equipment. In this paper, according to the different uses of the equipment in the coal preparation process, coal preparation equipment is divided into eight categories: screening machinery, crushing machinery, sorting machinery, dehydrating machinery, transportation machinery, feeding and preparation machinery, pumps and other equipment. Through the systematic analysis of the selection index of different equipment types, the process technical index, economy, reliability and manufacturer information are selected. The evaluation system of equipment selection expert system based on Analytic hierarchy process (AHP) is established. In the form of questionnaire, the experts of the industry and the first-line production workers are consulted, the weight coefficients of each evaluation index are counted, and the list of the selected equipment selection indexes according to the weight order is obtained by matrix calculation for the coal preparation designers. The leader of coal preparation plant and so on carries on the reference decision. According to the functional requirement analysis of coal preparation equipment drawing library and the evaluation index system of equipment selection, a primary intelligent coal preparation equipment selection system is established. The system uses SQL Server to build the database SQL as the server running environment, and realizes the development of the core part of the application software system of the B / S structure pattern based on Internet by using the. Net technology. The system mainly includes four core functions: coal preparation equipment drawing library management, coal preparation equipment factory management, coal preparation equipment selection management and coal preparation equipment comprehensive display platform. Finally, the network research on the computer aided design software (CPCAD) system of coal preparation plant is carried out. Combined with the developed coal preparation equipment selection system, the equipment map library of CPCAD is updated manually and periodically. With the help of the workflow management module in the automatic office platform developed by the Institute of process Control and Simulation Optimization, the planning realizes the networked collaborative work of CPCAD.
