基于PLC控制的锅炉实时监控系统

基于PLC控制的锅炉实时监控系统
摘要:随着现代工业技术的快速发展,锅炉的应用更加广泛。对于锅炉控制技术的研究有着广泛的经济价值。针对这一问题本毕业设计重点研究了基于PLC控制的锅炉实时监控系统。该系统就是一个简单的集散控制系统。借助现代计算机技术,实现对锅炉的集中控制,分散管理。
本设计主要涉及利用WinCC组态软件进行锅炉实时监控系统的设计步骤和开发过程,具体包括系统控制中心的设计,变量的定义,图形界面的制作,动态对象设计,全局脚本,以及报警系统和用户管理和项目安全设计。最后就如何使用PLC控制器以及如何运用step7程序设计软件进行控制程序的编辑作了简要的介绍。
本设计通过对锅炉系统的结构和工艺流程的系统分析,确定了合理的系统控制方案,包括三冲量水位控制系统和双交叉燃烧控制系统等方案的设计。选用西门子公司的S7-300PLC作为现场控制器,利用step7进行锅炉运作程序编写。同时采用与之配套的WinCC组态软件进行组态工作,建立一个人机交换界面,并实现PLC和组态软件之间通讯。通过使用远程计算机,实现对现场锅炉运行情况的实时监控和;,并且记录相应的数据。

ABSTRACT: With fast development of the modern industry technology, the usage of the boiler is more and more extensive. There is much Economy profit to study the control technology of boiler system. Aimed at this problem, the paper emphasize on the system to monitor and control instant boiler by means of PLC. That system is also a miniature Distributed Control System (DCS). Realizations to whole boiler system gather management and spread control by means of modern computer control technology.
In the design of system, it was textual to introduce a general design step and the development processes. Designing the system control center, defining the variable, creating the sketch interface, designing the dynamic state object, designing The overall situation script program, creating the alarm and protection system, designing customer management and the item safety, this text all has the detailed expatiation. At last introduced that how to use the PLC controller and how to made use of step 7 program software editing control programming in brief.
The paper passing is analytical to the structure and the work craft of the boiler system, make sure reasonable projects of the control system, include design the three variable water level control system and the double cross burn control system etc. Used to Siemens Corporation’s S7-300 PLC as the spots controller, making use of Siemens Corporation’s step7 software to write program of boiler operation procedure. This dissertation aim is passing to make use of this excellent development tool of a runtime software WinCC, carrying on the hardware choice and systems install reasonably, combining to the work craft of boiler, machine and monitoring to request to carry on the applied software development work, to compare with good man-machine interface, formation, develop a boiler system to monitor and control instant. realization to automation monitoring and management. Carry out instant monitoring and controlling to the spot boiler and record correspond of data passing network.
