I摘 要生料配料是水泥生产中极其重要的环节之一，生料配料质量控制的优劣直接关系着下游生产能否顺利进行本设计主要完成了水泥生料配料控制系统的设计，确定了以 ABB 公司生产AC800F 控制器并辅以 S800 系列 I/O 卡件构架集散控制系统采用了现场总线PROFIBUS DP 和以太网，实现现场管理层与操作管理层之间的数据通讯硬件设计中，完成了箱面布置图及端子排和变频电机集中控制原理图的电气图纸设计软件设计中，实现了生料配料过程中电机的顺序启停、直观形象的人机界面、报警等控制环节其中，针对配料皮带控制对象，采用以 PID 控制算法为中心，结合皮带秤零点标定，k 系数及皮带电机转速进行各物料的流量调节这也是本设计的重难点通过集散控制系统仿真平台（Emulator ） ，经测试可以实现本设计的电机顺序启停及报警等功能，达到了本设计的预期效果关键词：水泥生料配料；DCS；AC800F；PID；硬件设计IIABSTRACTThe material blending and pulverizaiton system is an important factor in cement production,the quality of the material blending and pulverizaiton system is very important to the subsequent production.The design of main shaft finished ration of raw cement control system design .Also confirmed by ABB AC800F controller with the production and S800 series I/O card distributed control system composed a complete. Using the fieldbus PROFIBUS DP and Ethernet, effective communication field management and operation management of the data communication between. The hardware design, finish the floor plan and terminal box and frequency conversion motor control diagram of the electrical design.This software design has implemented the start, stop control, vivid human-machine interface, data acquisition, alarm and so on. We use PID control to solve the imprecise of feedback. Choose frequency conversion control for measurement of the material.Material flow regulating relevant with zero calibration, k coefficient and motor speed.Through the distributed control system simulation platform, this design can be realized by testing the motor stopped and order and alarm functions, reached the expected effect of design.Key words： ration of raw cement；DCS；AC800F ；PID; hardware designIII目 录摘 要 ................................................................IABSTRACT...............................................................II1 前言 ..................................................................11.1 DCS 系统简介 .....................................................11.2 选题的背景及意义 .................................................11.2.1 国内外研究现状 ............................................11.2.2 选题的目的及意义 ..........................................32 总体方案设计 ..........................................................42.1 控制方案确定 .....................................................42.2 设计内容 .........................................................53 系统的工艺流程及控制要求 ..............................................73.1 工艺流程 .........................................................73.2 PID 调节控制 .....................................................83.3 皮带秤的设计 .....................................................83.4 电动机控制原理 ..................................................103.4.1 集中控制原理 ..............................................113.4.2 变频电机原理 ..............................................123.5 检测原理 ........................................................134 系统的硬件设计 .......................................................154.1 DCS 系统选型 ....................................................154.2 I/O 确定与编辑 ..................................................164.3 DCS 柜的总体设计 ................................................184.3.1 卡键及控制器的选型 ........................................184.3.2 DCS 箱面布置图设计 ........................................194.3.3 端子排的设计 ..............................................195 系统的软件设计 .......................................................245.1 控制系统组态设计 ................................................245.1.1 项目数的建立 ..............................................245.1.2 硬件设备组态 ..............................................255.1.3 现场总线网络组态 ..........................................275.2 过程站控制程序设计 ..............................................305.2.1 顺序启动程序 ..............................................315.2.2 标零和 K 系数程序设计 ......................................335.2.3 瞬时流量程序 ..............................................345.2.4 PID 调节程序 .............................................355.2.5 模拟量转换程序 ............................................355.2.6 流量配比设定与累计值程序 ..................................365.2.7 料位检测程序 ..............................................375.3 操作员站组态 .....................................................375.3.1 主监控界面组态 .............................................385.3.2 实时趋势显示 ...............................................395.3.3 系统报警设置 ...............................................395.3.4 变频监控设置 ...............................................40IV6 仿真调试 .............................................................426.1 配置 CBF 的 IP 地址和子网地址 .....................................426.2 配置网络闭环 ....................................................426.3 联机调试 ........................................................43总结 ...................................................................45参 考 文 献 ............................................................46致 谢 ...............................................................47附 录 .........................................................。
