A distributing hardware control system of the stretch - bending machine is designed by combining the advanced industry control computer and plc ( programmable logic controller ) 采用先進(jìn)的工業(yè)控制計(jì)算機(jī)與plc相結(jié)合的方式設(shè)計(jì)了分布式拉彎機(jī)硬件控制系統(tǒng)。
This paper introduced plc ( programmable logic controller ) as well as configuration software , and using their own characteristics to find application and do the research in the modern marine auxiliary boiler control system 摘要利用可編程序控制器以及組態(tài)軟件對現(xiàn)代船舶輔鍋爐控制系統(tǒng)進(jìn)行設(shè)計(jì)。
A more suitable control program was developed with plc ( programmable logic controller ) . the water source heat pump computer assistant design software was compiled to reduce time - period of product developments 在理論計(jì)算和設(shè)備選型的基礎(chǔ)之上,編制了水源熱泵機(jī)組計(jì)算機(jī)輔助設(shè)計(jì)軟件,對建立產(chǎn)品設(shè)計(jì)理論和縮短開發(fā)周期具有一定的參考價(jià)值。
The plc ( programmable logic controller ) has the advantages such as easily programming , good generality , high reliability , simple configuration of the control system and convenient maintenance etc . , so it is convenient to use it to design the control system 由于plc (可編程邏輯控制器)具有編程容易、通用性強(qiáng)、可靠性高、控制系統(tǒng)構(gòu)成簡單、維護(hù)方便等優(yōu)點(diǎn),用它來進(jìn)行控制系統(tǒng)的設(shè)計(jì)很方便。
An engineer case is introduced , which is about " the reconstruction of high voltage fan ' s speed - adjusting by frequency conversion and the design of plc ( programmable logic controller ) control system in shui cheng iron and steel company " . in this project , an advanced controlling technology , based on the method in this paper , is used to realize the closed loop control of discharge header pressure of two coke ovens 介紹“水鋼煤焦化公司鼓風(fēng)機(jī)高壓變頻調(diào)速及系統(tǒng)plc控制改造”的工程概況,對煤氣鼓風(fēng)機(jī)采用先進(jìn)的變頻調(diào)速技術(shù)和計(jì)算機(jī)控制技術(shù)進(jìn)行改造,實(shí)現(xiàn)對兩座焦?fàn)t集氣管壓力自動調(diào)節(jié)的閉環(huán)控制功能,既滿足了煤氣量的自動調(diào)節(jié)的要求,又避免了煤氣鼓風(fēng)機(jī)出口閥門的節(jié)流調(diào)節(jié),節(jié)能效果相當(dāng)可觀。
