PLC水泥生产自控设计+水泥磨机自动控制系统设计 摘要：本课题主要为采用组态软件和SIEMENS S7-200系列PLC进行水泥磨机的自动控制系统设计，实现水泥磨机的逆流程启动、顺流程停止、紧急情况下的设备急停、设备集中逻辑闭锁控制、单台设备的启停控制。
建材行业是与人类的生活息息相关的产业，水泥是在建材行业中一个主要的组成部分。国内对基础建设的大力投资带来了对高标准的水泥的持续需求，如今中国水泥产量己多年居世界首位。但我国并非一个水泥强国。高标准的水泥依然供不应求，能耗指标相对较高。为此，国家建材局提出了用先进技术的新型干法水泥生产来淘汰落后的立窑生产，提出了控制总量、调整结构、淘汰落后设备的方针。由于大多数企业资金比较紧缺，PLC技术的特性恰好能满足降低成本的需求；水泥生产过程为连续过程，需要大量的顺序和联锁控制，开关量点数占总数的80％，这非常符合价格低廉的PLC的控制特点。而S7-200系列小型PLC本文来自辣%文-论'文@网，毕业论文 www.751com.cn 加7位QQ324~9114找原文 (Micro PLC)可应用于各种自动化系统。紧凑的结构、低廉的成本以及功能强大的指令集使得S7--200 PLC成为各种小型控制任务理想的解决方案。

Cement production control design
Abstract: this topic is for the use of configuration software and SIEMENS S7-200 series PLC for cement mill automatic control system design, realization cement mill inverse process start, stop, the process of emergency equipment stop, equipment centralized logic locking control, single equipment start-stop control
Building materials industry is closely linked with human life industry, cement is in the building materials industry in a major part In infrastructure investment to bring the high standards of cement continued demand, now China's cement production for many years has the highest in the world But China is not a cement power High standards of cement is still in short supply, energy consumption index is relative taller Therefore, put forward the national building with advanced technology of new dry process cement production to the elimination of backward vertical kiln production, puts forward the general quantity control, structure readjustment, elimination of backward equipment policy Since most enterprise capital is in short supply, the characteristics of PLC technology just can satisfy the demand of cost reduction, Cement production process for continuous process, need a lot of sequence and interlock control, the switch quantity points or 80% of the total, it is very accord with cheap PLC control characteristics And S7-200 series small PLC (Micro PLC) can be applied to various automation system Compact structure, low cost and powerful instruction set makes S7-200 PLC for all small control tasks of the ideal solution
Force control monitoring configuration software is based on Windows operating system easy to use, can be integrated, based on component standard configuration software, it provides monitoring control and data collection all of the functions of necessary
