　　污水處理廠的控制系統(tǒng)設(shè)計(jì)基于現(xiàn)代先進(jìn)控制思想，采用分散控制、集中監(jiān)測管理的控制方式，采用以和利時(shí)公司LK系列可編程控制器(PLC)為核心的控制系統(tǒng)。基于LK自動化控制系統(tǒng)應(yīng)用于污水處理廠，完全能滿足污水處理工藝的要求，提供了一種高可靠性、低成本、更優(yōu)化的控制方案。
　　整個(gè)系統(tǒng)由1個(gè)中央控制室、4個(gè)現(xiàn)場PLC控制站組成。現(xiàn)場PLC控制站，由可編程序控制器(PLC)系統(tǒng)及檢測儀表組成，對污水處理廠各工藝過程進(jìn)行分散控制;再由中央控制室(CCR)，對全廠實(shí)行集中管理。中央控制室、PLC控制站之間的數(shù)據(jù)通訊采用高速的、實(shí)時(shí)的工業(yè)以太網(wǎng)，網(wǎng)絡(luò)結(jié)構(gòu)為環(huán)形，通訊速率為100Mbps，傳輸介質(zhì)為光纖。中央控制站設(shè)于綜合樓中控室;現(xiàn)場控制站設(shè)4個(gè)，分別位于進(jìn)水泵房(1#PLC控制站)、變配電間(2#PLC控制站)、鼓風(fēng)機(jī)房(3#PLC控制站)、污泥濃縮脫水機(jī)房(4#PLC控制站)，均采用和利時(shí)公司 LK系列PLC。
　　整個(gè)系統(tǒng)采用二級網(wǎng)絡(luò)結(jié)構(gòu)，即生產(chǎn)管理網(wǎng)和生產(chǎn)控制網(wǎng)，將過程實(shí)時(shí)數(shù)據(jù)、運(yùn)行操作監(jiān)視數(shù)據(jù)信息同非實(shí)時(shí)信息及共享資源信息分開，分別使用不同的網(wǎng)絡(luò)。有效地提高了通訊的效率，降低了通訊負(fù)荷。生產(chǎn)管理網(wǎng)采用工業(yè)以太網(wǎng)，網(wǎng)絡(luò)結(jié)構(gòu)為環(huán)形，傳輸介質(zhì)為光纖。生產(chǎn)控制網(wǎng)采用現(xiàn)場總線形式，采用PROFIBUS國際通用的開放式現(xiàn)場總線，傳輸介質(zhì)為屏蔽雙絞線。
　　污水處理廠自動化控制系統(tǒng)控制方式設(shè)計(jì)為現(xiàn)場設(shè)備就地手動控制、自動化控制系統(tǒng)遠(yuǎn)程手動控制、自動化控制系統(tǒng)遠(yuǎn)程自動控制三種控制方式。三種方式的級別由高到低依次為就地手動、遠(yuǎn)程手動、遠(yuǎn)程自動。
