Abstract: This paper briefly reviewed the history of China-made PLC and presented the domestic market situation of PLC, mainstream products of China-made PLC, PLC standards, and relevant national policies. And the existing gaps between foreign and domestic PLC products were analyzed from some aspects including PLC performance indicators, logic programming software, network protocols, product categories, and standardization. Then this paper tried to propose a solution to develop the China-made PLC, combining the characteristics of PLCs of European, American, and Japanese systems. Led by the key projects in the fields of defense industry and critical infrastructure, the China-made PLC will be developed and used based on the domestic independent software and hardware.
Key words : China-made PLC;current development situation;independence and controllability
0 引言
可編程邏輯控制器(PLC)是一種面向工業(yè)控制的實(shí)時嵌入式計算機(jī),通過專用的控制語言可以實(shí)現(xiàn)各類邏輯控制及流程控制。以PLC為中心,可以構(gòu)建面向國防軍工、制造、軌道交通、電力、水利、市政等領(lǐng)域的自動化控制系統(tǒng)。PLC系統(tǒng)已經(jīng)成為現(xiàn)代數(shù)字工業(yè)體系的“大腦”,可全面掌握各類核心工藝數(shù)據(jù)及運(yùn)行數(shù)據(jù),直接決定和保障國家工業(yè)體系、國防裝備體系安全健康運(yùn)行。
1 國內(nèi)PLC發(fā)展現(xiàn)狀
PLC問世近60年來,實(shí)現(xiàn)了工業(yè)控制領(lǐng)域繼電器接線邏輯到存儲邏輯的飛躍,功能從弱到強(qiáng),實(shí)現(xiàn)了邏輯控制到數(shù)字控制的進(jìn)步,應(yīng)用領(lǐng)域從小到大,實(shí)現(xiàn)了單體設(shè)備簡單控制到復(fù)雜運(yùn)動控制、過程控制以及集散控制等各種任務(wù)的跨越。
