文档介绍：基于组态王的H2S浓度监测系统的研究与实现
摘要
可编程控制器是一种应用很广泛的自动控制装置,它将传统的继电器控制技术、计算机技术和通讯技术融为一体,具有控制能力强、操作灵活方便、可靠性高、适宜长期连续工作的特点,非常适合浓度监测的要求。
在工业领域,随着自动化程度的迅速提高,用户对控制系统的过程监控要求越来越高,人机界面的出现正好满足了用户这一需求。人机界面可以对控制系统进行全面监控,包括过程监测、报警提示、数据记录等功能,从而使控制系统变得操作人性化、过程可视化,在自动控制领域的作用日益显著。
本文主要介绍了基于罗克韦尔公司Control Logix系列的可编程控制器和亚控公司的组态软件组态王的浓度控制系统的设计方案。编程时只需运用RSLogix5000编程软件对H2S控制器进行配置。利用组态软件组态王设计人机界面,实现监测系统的实时监控、数据的实时采集与处理。实验证明,此系统具有快、准、稳等优点,在气体浓度控制领域能够广泛应用。

Monitoring bining PLC with Kingview
for H2S concentration
ABSTRACT
Programmable Logic Controller (PLC) is a kind of automatic control equipment which is widely used in the industrial manufacture. It merges the traditional control technology, computer munication technologies with a strong ability to control, flexible operation, high reliability and suitable for long-term characteristics of continuous work. It is very suitable for temperature control requirements.
In the industrial field, with the rapid increase in the degree of automation, it is more and more important to monitor the process of control system for the users. The emergence of human-machine interface meets the needs of users. Human-machine interface prehensively monitor the control system, including process monitoring, alarm, data logging and other functions, so that the control systems have e user-friendly operation, the process of visualization and it will play more and more important part in the field of automatic control.
This essay mainly introduces a design of monitoring bining Rockwell programmable logic controller (PLC) and configuration software Kingview which is developed by Beijing pany. When programming, we use the RSLogix5000 software operates to the H2S Controller. In order to monitor the control system and process data in actual time, we designed Human Machine Interface(HMI)with the configuration software Kingview. The result of experiment proves that this monitoring system could run quickly, accurately and have good stability, whic
