基于PLC的水泥厂水处理控制系统的设计(梯形图,硬件连接图)

基于PLC的水泥厂水处理控制系统的设计(梯形图,硬件连接图)(任务书,开题报告,论文说明书10000字,梯形图,硬件连接图)
摘要
本设计背景是在收到工艺部门的水处理工艺流程图后，按照要求设计一种水处理控制系统。工艺流程图显示本水泥厂用水主要分为生产现场的工业用水、生活区的生活用水、厂区道路清洗用水以及消防系统用水。得到企业导师的建议后，决定在水处理控制系统中应用S7- 300系列的PLC，使深井中的生水经过一系列的水处理设备后达到使用要求。
文章首先介绍了本课题的目的和意义及国内外水处理控制系统的发展状况然后根据水处理工艺流程图阐述了系统的工作原理，并根据仪表清单画出仪表配置图。接着按照水处理要求设计PLC控制系统，先进行水处理控制系统的硬件设计，再进行水处理控制系统的软件设计，并用PLCSIM对程序进行仿真运行。最后用PCS7软件进行画面组态。

Abstract
The background of this design is to design a water treatment control system as required after receiving the water treatment process flow diagram of the process department. The process flow chart shows that the water used in the cement plant is mainly divided into industrial water at the production site, domestic water in the living area, road cleaning water in the plant area, and water for the fire protection system. After receiving the advice of the company's instructors, it was decided to apply the S7-300 series PLC in the water treatment system, so that the raw water in the deep well passed the series of water treatment equipment and reached the use requirements.
The article first introduces the purpose and significance of this topic and the development status of the water treatment control system at home and abroad. Then the working principle of the system is explained according to the water treatment process flow chart, and the instrument configuration diagram is drawn according to the instrument list. Then design the PLC control system according to the water treatment requirements, first carry out the hardware design of the water treatment system, then carry out the software design of the water treatment system, and use PLCSIM to simulate the operation of the program. Finally, the screen configuration is performed using PCS7 software.
