基于PLC風(fēng)機(jī)控制器設(shè)計(jì)

摘要：為了對(duì)風(fēng)機(jī)進(jìn)行時(shí)時(shí)監(jiān)控，得到穩(wěn)定可靠的風(fēng)機(jī)控制系統(tǒng)，對(duì)風(fēng)機(jī)系統(tǒng)的結(jié)構(gòu)和風(fēng)機(jī)運(yùn)行過程進(jìn)行了分析，采用PCS(Process Control System)作為該風(fēng)機(jī)監(jiān)控系統(tǒng)的設(shè)計(jì)方案。計(jì)算機(jī)作為上位機(jī)提供良好的人機(jī)界面，進(jìn)行全系統(tǒng)的監(jiān)控和管理；而PLC作為下位機(jī)，執(zhí)行可靠有效的分散控制。對(duì)風(fēng)機(jī)運(yùn)行流程進(jìn)行分析并作出主電機(jī)控制邏輯設(shè)計(jì)和油站邏輯設(shè)計(jì)，寫出PLC程序。使用MCGS組態(tài)軟件監(jiān)控風(fēng)機(jī)控制系統(tǒng)的運(yùn)行，時(shí)時(shí)顯示被檢測(cè)量，當(dāng)風(fēng)機(jī)運(yùn)行異常時(shí)進(jìn)行報(bào)警。

PLC-based controller design for fans

Abstract：In order to carry out constant monitoring of fans, to get a stable and reliable fans control system, analysis the structure of the fan systems and fan running process. Use PCS (Process Control System) as part of the fan monitoring and control system. Use PC computer as a good man-machine interface to monitor and manage the system; use PLC as the hypogynous machine to carry out reliable and effective implementation of decentralized control. Analysis the Fans running process and design the main motor logic control and petrol stations logic control, write PLC program. Use the MCGS configuration software to monitor fans control system running at all times and show the amount detected, alarm when the fan is running abnormal.
