摘要:工业锅炉作为我国工业生产和集中供热的重要能源转换设备,能耗巨大,长期处在耗能大、高污染的生
产状态。然而,目前我国大多数锅炉控制系统自动化不高、安全性低,效率普遍低于国家标准,过滤作为将一
次能源转化为二次能源的重要设备之一,提高锅炉控制水平作为研究。基于 Niagara 开发平台,选取过程控制中
的实验对锅炉控制系统进行开发。将原 PLC 控制技术进行替换,通过硬件搭建、软件开发、数据通信与界面设
计集成出一套过程控制实验系统。该论文首先介绍了课题研究意义,基础理论知识,其中包括 PLC 相关的李玲
以及过程控制系统的理论,描述锅炉烧水、水位控制系统的工作原理。通过实验测试表明,该系统的水位控制
和温度控制运行可靠,同时体现出 Niagara 开发平台可视化图形编程的优越性、互联网访问便捷性、工业控制网
络的融合性和强大的设备兼容性。

Abstract:As an important energy conversion equipment in China's industrial production and central heating, industrial
boilers consume huge energy and have long been in the production state of energy consumption and high pollution. How-
ever, at present, most of the boiler control system in Our country is not high automation, low security, efficiency is gener-
ally lower than the national standard, filtration as one of the important equipment to transform the primary energy into th-
is energy, improve the boiler control level as a research. Based on Niagara development platform, the boiler control sys-
tem is developed by selecting experiments in process control. Replace the original PLC control technology, through hard-
ware construction, software development, data communication and interface design integrated a set of process control ex-
perimental system. This paper first introduces the significance of the subject research, basic theoretical knowledge, inclu-
deing PLC related Li Ling and process control system theory, describes the boiler water, water level control system wor-
king principle. The experimental results show that the water level control and temperature control of the system are re-
liable, and the advantages of Niagara development platform visual graphics programming, Internet access, integration of
industrial control network and strong equipment compatibility are reflected.

0.1 锅炉控制系统设计目的和意义
目前,相当多的锅炉仍旧采用传统方式控制,
主要依靠操作员手工来完成,这样就要求锅炉操作
员时刻都要在现场监控锅炉运行情况,并且要对整
个锅炉系统的运行过程以及过程中各个环节的相
互影响已达工艺要求。其过程复杂,而且还凸显了
很多弊端。操作容易导致安全事故,而且参数控制
不够准确及时,而导致能源和资源的浪费严重,另
外运行维护成本也高,劳动效率低下。
随着科学技术的飞速发展,带动社会生产的发
展,人类对能源的需求不断增加,世界上发达国家
