A distributing hardware control system of the stretch - bending machine is designed by combining the advanced industry control computer and plc ( programmable logic controller ) 采用先進的工業(yè)控制計算機與plc相結合的方式設計了分布式拉彎機硬件控制系統(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)進行設計。
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 在理論計算和設備選型的基礎之上,編制了水源熱泵機組計算機輔助設計軟件,對建立產(chǎn)品設計理論和縮短開發(fā)周期具有一定的參考價值。
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、可靠性高、控制系統(tǒng)構成簡單、維護方便等優(yōu)點,用它來進行控制系統(tǒng)的設計很方便。
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機高壓變頻調速及系統(tǒng)plc控制改造”的工程概況,對煤氣鼓風機采用先進的變頻調速技術和計算機控制技術進行改造,實現(xiàn)對兩座焦爐集氣管壓力自動調節(jié)的閉環(huán)控制功能,既滿足了煤氣量的自動調節(jié)的要求,又避免了煤氣鼓風機出口閥門的節(jié)流調節(jié),節(jié)能效果相當可觀。
