摘  要

 可編程控制器是一種應(yīng)用很廣泛的自動(dòng)控制裝置，它將傳統(tǒng)的繼電器控制技術(shù)、計(jì)算機(jī)技術(shù)和通訊技術(shù)融為一體，具有控制能力強(qiáng)、操作靈活方便、可靠性高、適宜長(zhǎng)期連續(xù)工作的特點(diǎn)，非常適合濃度監(jiān)測(cè)的要求。
 在工業(yè)領(lǐng)域，隨著自動(dòng)化程度的迅速提高，用戶對(duì)控制系統(tǒng)的過(guò)程監(jiān)控要求越來(lái)越高，人機(jī)界面的出現(xiàn)正好滿足了用戶這一需求。人機(jī)界面可以對(duì)控制系統(tǒng)進(jìn)行全面監(jiān)控，包括過(guò)程監(jiān)測(cè)、報(bào)警提示、數(shù)據(jù)記錄等功能，從而使控制系統(tǒng)變得操作人性化、過(guò)程可視化，在自動(dòng)控制領(lǐng)域的作用日益顯著。
 本文主要介紹了基于羅克韋爾公司Control Logix系列的可編程控制器和亞控公司的組態(tài)軟件組態(tài)王的濃度控制系統(tǒng)的設(shè)計(jì)方案。編程時(shí)只需運(yùn)用RSLogix5000編程軟件對(duì)H2S控制器進(jìn)行配置。利用組態(tài)軟件組態(tài)王設(shè)計(jì)人機(jī)界面，實(shí)現(xiàn)監(jiān)測(cè)系統(tǒng)的實(shí)時(shí)監(jiān)控、數(shù)據(jù)的實(shí)時(shí)采集與處理。實(shí)驗(yàn)證明，此系統(tǒng)具有快、準(zhǔn)、穩(wěn)等優(yōu)點(diǎn)，在氣體濃度控制領(lǐng)域能夠廣泛應(yīng)用。

Monitoring system combining 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 and communication 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 can comprehensively monitor the control system, including process monitoring, alarm, data logging and other functions, so that the control systems have become 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 system combining Rockwell programmable logic controller (PLC) and configuration software Kingview which is developed by Beijing Yakong Company. 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, which is the advantage of the monitoring system. This monitoring system has been widely used in the industrial concentration monitoring field.
