西門子工業自動化研究綜述
摘要:隨著科學技術的發展,工業控制的技術發展越來越快,工業控制技術使得工廠的生產效率大幅提高,而工業控制器PLC、工業PC等的應用也大幅度提高了系統的自動化程度,觸摸屏,人機界面的使用也使得工業現場的監控更加方便,變頻器的發展也使得控制的精度越來越高。現場總線的發展使得系統的通訊更加方便。本文主要對工業控制進行一下初步的了解。
關鍵詞:PLC;人機界面;現場總線
引言
工業自動化就是工業生產中的各種參數為控制目的,實現各種過程控制,在整個工業生產中,盡量減少人力的操作,而能充分利用動物以外的能源與各種資訊來進行生產工作,即稱為工業自動化生產,而使工業能進行自動生產之過程。
所謂的參數控制就是通過計算機控制系統,利用各種算法使系統達到穩態。減少人力操作是通過使用計算機和可編程控制器就是PLC,來實現整個工廠的自動控制的。監控方面也采用了集中監控和部分分散監控相結合的原則,對工廠自動化系統而言,使用人機界面軟件監控,如西門子公司的WINcc,組態王,萬維公司的InTouch,還有北京亞控科技發展有限公司開發的組態王kingview等等。對系統局部的控制或者監測可以使用觸摸屏。在運動控制和過程控制過程中,變頻器的使用也是十分的廣泛,主要用于交流電機的調速。而西門子公司對工廠自動化控制過程所要用到的設備的生產和研發也是非常的到位的。
一.
PLC(Programmable Logic Controller)就是可編程邏輯控制器。德國西門子公司是上研制PLC早的少數幾個公司之一。歐洲臺PLC是由該公司在1973年研制成功的,1975年推出了SIMATIC S3系列PLC,1979年推出了SIMATIC S5系列,20世紀末又推出了SIMATIC S7系列的 PLC。
西門子S7系列PLC更接近于現場要求:高可靠性,減少了中間接口,具有多中斷、現場總線口、集成電位器、定時器、 計數器、碼盤接口等成功能,以及強大的網絡功能:RS232/485接口及多種現場總線標準、遠程I/O,還可以作為DCS的下位站和PC機的下位機。同時支持多種編程語言,多種編程環境和可配套的集成軟件。【1】
S7系列PLC系統結構如圖1所示。【2】
