介紹了以PLC為核心的分布式控制系統(tǒng)在污水處理系統(tǒng)中的應(yīng)用。具體敘述了控制系統(tǒng)的結(jié)構(gòu)、任務(wù)分配及實(shí)現(xiàn)、控制方式和程序設(shè)計(jì)思想.控制系統(tǒng)采用集中監(jiān)測管理、分散控制的方式，上位機(jī)負(fù)責(zé)現(xiàn)場設(shè)備的遠(yuǎn)程控制和監(jiān)視，軟件采用Intouch7. 0編制。PLC本地站負(fù)責(zé)對具體的工藝、設(shè)備、主要被控參數(shù)進(jìn)行控制及采集各種運(yùn)行數(shù)據(jù)，程序設(shè)計(jì)采用具有在線跟蹤和離線仿真功能的Concept 2. 2XL軟件。上位機(jī)與PLC之間采用組網(wǎng)簡單、運(yùn)行速度快、通信穩(wěn)定性強(qiáng)的MB+網(wǎng) 。整個(gè)控制系統(tǒng)成功地解決了PLC在污水處理中的自動化控制問題，提高了污水處理設(shè)備運(yùn)行效率和管理水平。
近年來，為了實(shí)現(xiàn)高質(zhì)量、低消耗、穩(wěn)定可靠的運(yùn)行。國內(nèi)外許多污水處理廠采用了現(xiàn)代先進(jìn)控制技術(shù)和計(jì)算機(jī)技術(shù)，從而構(gòu)成計(jì)算機(jī)監(jiān)督、控制、管理系統(tǒng).使系統(tǒng)優(yōu)化運(yùn)行。而可編程邏輯控制器（PLC）則是以微處理器為核心。綜合了計(jì)算機(jī)技術(shù)自動控制技術(shù)和通信技術(shù)而發(fā)展起來的一種新型、通用的自動控制裝置。具有結(jié)構(gòu)簡單、性能優(yōu)越、可靠性高、靈話通用、易于編程、使用方便等優(yōu)點(diǎn)等。銀川市第一污水處理廠采用了SBR工藝及以PLC為核心的控制系統(tǒng)，日處理污水10 x 104 t處理后的達(dá)標(biāo)污水可用于農(nóng)業(yè)灌溉。
1 控制系統(tǒng)結(jié)構(gòu)
控制系統(tǒng)采用“集中監(jiān)測管理，分散控制”的方式。模擬屏、上位機(jī)、集線器、打印機(jī)位于中控室，二臺PLC位于控制現(xiàn)場。采用這種結(jié)構(gòu)可使生產(chǎn)過程中的信息能夠集中管理，以實(shí)現(xiàn)整體操作、管理和優(yōu)化。同時(shí)，也使得控制危險(xiǎn)分散，提高系統(tǒng)可靠性。
1.1上位機(jī)
中控室的兩臺上位計(jì)算機(jī)采用PII級工控機(jī)，運(yùn)行Windows NT操作系統(tǒng)。上位機(jī)負(fù)責(zé)現(xiàn)場設(shè)各的遠(yuǎn)程控制(全自動控制、自動控制、點(diǎn)動控制)和監(jiān)視，利用Intouch7. 0工程軟件包提供良好的人機(jī)對話界而，以查詢方式從PLC獲取有關(guān)參數(shù)和設(shè)備狀態(tài)信息，以棒圖形式在CRT上直觀顯示出來，同時(shí)打印必要的數(shù)據(jù)，供主控及管理人員指導(dǎo)生產(chǎn)。監(jiān)控界而包括系統(tǒng)總圖、系統(tǒng)分圖、模擬量一覽表、參數(shù)設(shè)置、報(bào)警窗、歷史趨勢、登錄窗等界而.在系統(tǒng)總圖里，運(yùn)行人員能夠監(jiān)視所有控制設(shè)備的運(yùn)行狀態(tài)、設(shè)備事故及液位、流量等信號.在系統(tǒng)分圖里，操作人員能夠?qū)λ锌刂圃O(shè)備進(jìn)行單機(jī)點(diǎn)動運(yùn)行操作、成組自動運(yùn)行操作或全廠全自動操作并監(jiān)視。同時(shí)上位機(jī)2兼做編程器.中控室另設(shè)置一個(gè)鑲嵌式模擬屏，由上位機(jī)1控制，用以直觀顯示全廠工藝流程及主要參數(shù)值。
