基于89S51单片机的锅炉给水控制系统

锅炉是现代工业、企业、事业单位工作和生产的动力之源,为确保安全,稳定生产,锅炉的自动控制是十分重要的。而汽包水位是锅炉运行中一个非常重要的被控变量,保证水位在给定范围内对整个机组运行的安全性和经济性有着重要意义.本文针对大容量,高参数的锅炉,通过分析锅炉给水系统的控制任务和汽包水位的动态特性,以及常用的控制方案,提出了基于89S51的水位控制系统,并根据控制要求设计了软件方案。通过对水位的实时监控和调节,将汽包水位控制在工艺允许的范围之内。本系统控制精度高,可操作性强,安全性高。

Application of 89S51 Single Chip Computer in Water-Supply Control System of Boiler

The boiler is the source of power of running and producting for modern industry,enterprise and institutions.The auto-control is quite important to ensurethe production and security.And the steam bag water level is one of the important variables to be controlled in the whole running process of the boiler.What’smore,ensuring water level in the given range takes an important part for the safty and economy of the set。For the high capacity and parameter boilers,throughanalyzing the control assignment of water-supply system of boiler and the dynamic charateristics of steam bag water level,this paper designs a water level controlsystem based on 89S51 single chip computer and software project based on the need of the control.The system can control steam bag water level in the technologicalrange through real-time monitoring and regulating the water level,and offer high accuracy,operability and security.
