可較好地保證監(jiān)控實(shí)時(shí)性;管理層采用靈活的計(jì)算機(jī)網(wǎng)絡(luò),便于網(wǎng)絡(luò)互連和系統(tǒng)擴(kuò)展。如某電廠4?300MW機(jī)組輔助系統(tǒng)DCS將除灰控制系統(tǒng)、除渣控制系統(tǒng)和凝結(jié)水精處理控制系統(tǒng)、補(bǔ)水、凈水、反滲透和輸煤控制系統(tǒng)等七個(gè)互相獨(dú)立的系統(tǒng)組成一個(gè)DCS系統(tǒng),并要連到主控室中,在主控室的上位機(jī)上統(tǒng)一對(duì)各系統(tǒng)進(jìn)行監(jiān)控,在單元機(jī)組的主控室中設(shè)三臺(tái)監(jiān)控上位機(jī),它們互為熱備,其中一臺(tái)兼作工程師站,三臺(tái)上位機(jī)各有獨(dú)立的數(shù)據(jù)庫(kù),信息均來(lái)自各輔助系統(tǒng)的PLC,通過(guò)

和光纜與各輔助系統(tǒng)的網(wǎng)關(guān)相連,一起組成一個(gè)Ethernet網(wǎng)與各輔助系統(tǒng)的通訊網(wǎng)絡(luò)連接起來(lái),從而實(shí)現(xiàn)對(duì)各自PLC的監(jiān)控。 4.4 輔助系統(tǒng)計(jì)算機(jī)集中監(jiān)控系統(tǒng)應(yīng)具備以下功能 (1)完善的工藝流程圖顯示,設(shè)備狀態(tài),控制狀態(tài)及運(yùn)行參數(shù)的實(shí)時(shí)顯示功能,根據(jù)工藝過(guò)程和監(jiān)控的具體要求采用多層顯示結(jié)構(gòu),包括概貌顯示、功能組顯示和設(shè)備細(xì)節(jié)顯示, (2)不同系統(tǒng)及畫(huà)面的切換及控制設(shè)備的操作功能,系統(tǒng)及設(shè)備選擇方便簡(jiǎn)單,并有操作權(quán)限的設(shè)置與限制,以滿足不同操作層次的要求, (3)參數(shù)報(bào)警及事故追憶功能, (4)歷史參數(shù)與曲線、事故追憶與操作記錄、報(bào)警與報(bào)表的打印功能, (5)上述各種功能的生成,參數(shù)的修改功能(即工程師站功能), (6)可靠的系統(tǒng)自診斷功能,以便能夠及時(shí)診斷系統(tǒng)硬件及通訊網(wǎng)絡(luò)的故障。 5 應(yīng)注意的問(wèn)題 (1)根據(jù)全廠自動(dòng)化水平的整體要求和外圍系統(tǒng)的工藝具體特點(diǎn),確定合理先進(jìn)的整體監(jiān)控方案,以使其既能提高全廠自 動(dòng)化水平滿足電廠管理改革發(fā)展的需要,又結(jié)合現(xiàn)場(chǎng)的實(shí)際特點(diǎn),切實(shí)可行。 (2)保證具體方案的安全可靠性。確定的具體技術(shù)方案首先要確保系統(tǒng)運(yùn)行的安全要求,采用冗余技術(shù),并設(shè)計(jì)完善的自檢和報(bào)警功能,確保整體網(wǎng)絡(luò)、電源及PLC控制的可靠性。 (3)人機(jī)對(duì)話界面應(yīng)清晰明了,主輔畫(huà)面之間、總貌與詳圖之間、各個(gè)子系統(tǒng)之間及各個(gè)不同的工藝系統(tǒng)之間切換應(yīng)方便快速,應(yīng)有正確的操作指導(dǎo)和順控運(yùn)行提示,操作人員易于監(jiān)控。重要操作應(yīng)有提示和確認(rèn),避免誤操作。 (4)現(xiàn)場(chǎng)預(yù)留好調(diào)試及檢修接口,便于現(xiàn)場(chǎng)調(diào)試及以后的檢修工作。系統(tǒng)還應(yīng)有一定的可擴(kuò)展性和在線動(dòng)態(tài)修改能力,以適應(yīng)以后的發(fā)展和輔助控制系統(tǒng)的運(yùn)行優(yōu)化。 (5)輔助系統(tǒng)的現(xiàn)場(chǎng)環(huán)境比較惡劣,應(yīng)重視現(xiàn)場(chǎng)一次設(shè)備的選型和現(xiàn)場(chǎng)安裝調(diào)試工作。實(shí)踐表明,一次設(shè)備質(zhì)量的好壞electric control cabinet at the scene and were shocked by the new products used by our company. On site maintenance engineers not only feel the high quality of Ouchen products, but also enjoy the continuous new achievements and achievements brought by Ouchen's independent innovation. They always believe that Ouchen products are very trustworthy.

Although the domestic PLC products are low, some owners still have some doubts about using domestic products. Through our personal experience, the key is to find the right products, such as Ouchen, who is dedicated to building domestic high-end brands. Now it has won more and more customers in grain machinery and feed production line. In the field of industrial automation, programmable controller and industrial computer are two kinds of control equipment that people have to mention. They are the basic equipment of most automation systems. The development of the software of the controller is the perfect embodiment of the performance requirements of various
