【摘要】 配料过程是钢铁冶金、建筑材料生产等行业中一个非常重要的环节。配料质量的好坏直接影响着后续产品的产量和质量。因此优质高效的配料控制系统是现代化的生产企业追求优质高效不可缺少的先决条件。鉴于攀钢目前仍有部分配料生产线采用的是传统的靠人工手动调节圆盘给料机转速来控制下料量的方式进行配料，已经不能适应攀钢发展的需要，因此设计了本套基于WINDOWS操作平台的烧结自动配料系统。系统主要包括：1．根据生产需要，设计了一种基于WINDOWS操作平台、各给料圆盘分散控制、上位机集中监控与管理的集散型控制系统。结果表明，该自动配料系统在实际应用过程中方便有效。2．针对常规PID控制存在的一些缺陷，设计了一种分段式积分分离法PID控制器。使用结果表明，该控制器简单有效。3．根据现场环境，对物料的计量方式进行了优选。4．为了方便用户对生产过程的监控与管理，设计了基于WINDOWS操作平台下的数据管理系统。系统功能包括：班日综合报表、生产运行报表及随机报表等生产管理报表的存储、显示及打印输出：物料配比、物料水分、物料名称、物料计量参数、控制参数等系统参数表的设置、查询、显示及打印输出；每种物料超差报警提示、每种物料的历史趋势及实时控制趋势显示。更多还原

【Abstract】 The batching process is a very important sector in industries such steel metallurgy and building materials. The quality of batching directly affects the output and quality of follow-up products, thus a high quality and high efficiency batching control system is a precondition necessary to the high quality and high efficiency that modern industries pursue. As some of the batching lines of Pangang still use the traditional manual way to adjust the speed of disk feeders to control the volume of material supply, which no longer meets the requirement of the prodcution, this sintering auto-batching system based on WINDOWS is designed. The features of the system are:1. Based on the production needs, a distributed control system with decentralized control of the feeding disks and centralized PC control is designed. The performance shows that the batching system provides convenience and flexibility to changing the disks.2. With regard to some defects in conventional PID control, a sectioned integral partitioning PID controller is designed. The performance shows that the controller is simple and effective.3. Based on the site condition, the measuring method of the materials is optimized.4. To make it convenient for the user to manage the production process, a data management system based on WINDOWS is designed. The system functions include: storage, display and printing of daily shift report sheet, production sheet and random sheet etc. ; setup, query, display and printing of system parameters of material proportioning, material water content, material measuring parameters, control parameters etc. ; material shortage alarming and the historical trend and realtime control trend showing.更多还原
