Secondly , alterability of sampling frequency was required in the work of this paper 其次,本課題還要求采樣率可變。
Uenmis is developed on the basis of the alterability of system , the software engineering theory and the current technology of nmis system development . it is designed by adopting the method of structural designed , structuring and modularization Uenmis系統(tǒng)設(shè)計和開發(fā)從系統(tǒng)的變更性入手,以軟件工程理論和現(xiàn)有的mis系統(tǒng)開發(fā)技術(shù)為指導(dǎo),采用sd方法設(shè)計,層次結(jié)構(gòu)法和模塊法相結(jié)合的開發(fā)方法。
According with the specialty of the grinding productive line , the advanced agility and credible plc integrated control system is designed to in place of relay control system that owns bad reliability and bad alterability . the environment is improved . it also meets the tidal current of material transportation controlling , tally with the up trend of the science and technology in the sugar - refinery 為解決糖廠壓榨提汁生產(chǎn)線的傳統(tǒng)繼電控制系統(tǒng)的可靠性與可更改性差,操作工人工作環(huán)境極差等缺點(diǎn),結(jié)合糖廠科技發(fā)展的趨勢與當(dāng)前物料輸送線多采取集中控制的潮流,設(shè)計采用了先進(jìn)、靈活、可靠的plc控制技術(shù)對壓榨提汁生產(chǎn)線進(jìn)行集成控制。
