仪表自动化实验装置设计(温度)剖析.doc

摘要 本文主要介绍的是基于组态软件的锅炉温度监控系统设计，利用实验室所提供的过程控制对象搭建锅炉温度测控系统平台。用装有MCGS组态软件的电脑作为上位机与宇电仪表进行通讯，可以实现报警、修改参数、历史曲线、实时曲线、实时报表、历史报表等，控制层和现场层主要由作为控制器的宇电仪表、作为检测传感器的Pt100热电阻和作为执行机构的三相可控硅移相调压设备组成，由上位机读写仪表内的相关参数，实现对锅炉温度的监控。根据自行设计的图纸进行接线并调试，主要完成上位机与仪表通讯和PID参数整定的工作，经过自整定后再进行参数微调，达到了很好控制效果。本文设计的温度监控系统在仪表实验室实际运行，稳定可靠，且具有较好的抗干扰性能，经改造后可以应用于实际的锅炉监控系统中。 关键词This paper mainly introduces the is based on configuration software boiler temperature monitoring system design, use laboratory provided by the process control object structures temperature controlling system platform boiler. Equipped with MCGS software with the computer as a PC with yu electrical instrument for communication, may realize the alarm, modification parameter, historical curve, real-time curves, real-time statements, historical statements and so on, control layer and on-site layer consists mainly of yu electricity meter as controller, as the detection sensor Pt100 thermal resistance and as actuator three-phase SCR phase shifting composed by regulating equipment, computer literacy meter inside the related parameters, and to realize the boiler temperature monitoring. According to his own design drawing wiring and debugging, mainly completes PC and instrumentation communications and PID parameters setting work, after auto-tuning again after parameter tuning, achieves a good control effect. This design temperature monitoring system in the actual operation instrument laboratory, stable and reliable, and has good anti-disturbance performances, after modification of the boiler can be applied in practical monitoring system. Keywords: MCGS、temperature control tuning、PID、monitoring system目录 摘要 1 Abstract 2 第一章 绪论 1 1.1选题背景 1 1.2温度监控系统研究目的及意义 1 1.3本课题研究的内容 2 第二章 温度监控系统简介 3 2.1过程控制系统简介 3 2.2基于组态软件的温度监控系统方案简介 4 2.2.1 一般计算机测控系统组成 4 2.2.2 基于MCGS的温度监控系统方案 4 第三章 温度监控系统硬件设计 5 3.1监控系统硬件组成结构图 5 3.2上位机 6 3.3基于宇电仪表的控制系统设计 7 3.3.1仪表功能介绍 7 3.3.2三相可控硅移相调压器原理与特性 9 3.3.4基于宇电仪表的控制系统搭建 11 第四章 监控系统软件设计 12 4.1 MCGS组态软件简介 12 4.2基于MCGS的温度监控界面设计 13 4.3 MCGS组态
