詳細(xì)描述：   

基于PLC的自動發(fā)貨系統(tǒng) 
      導(dǎo)讀： 新設(shè)計(jì)開發(fā)的成品油自動發(fā)貨系統(tǒng)不采用現(xiàn)成產(chǎn)品發(fā)油控制裝置或系統(tǒng)，而采用工程化的技術(shù)路線，實(shí)現(xiàn)一個(gè)有自己特點(diǎn)的個(gè)性化完美的自動控制系統(tǒng)。 

　　(2)運(yùn)行環(huán)境 

　　監(jiān)控工作站：Win2000Professional； 

　　業(yè)務(wù)工作站：Win2000Server 

　　(3)軟件功能 

　　報(bào)表查詢管理功能，該軟件的功能能滿足用戶提出的要求，能對發(fā)油的數(shù)據(jù)管理、查詢、制表。能在網(wǎng)絡(luò)的客戶端運(yùn)行CONTROLENGINEERINGChina版權(quán)所有，訪問現(xiàn)場的發(fā)油情況以及現(xiàn)場各個(gè)設(shè)備的當(dāng)前工作狀態(tài)，鶴位的狀態(tài)，發(fā)油歷史數(shù)據(jù)信息、匯總等功能。這就實(shí)現(xiàn)了辦公室層對現(xiàn)場作業(yè)的一個(gè)監(jiān)視、實(shí)時(shí)管理。 

　　4.幾個(gè)控制功能 

　　a.流速控制 

　　對于鶴管和加油槍要求保持一定的流量(流速)范圍，以保證加油作業(yè)的安全和效率。由于下列情況可能造成發(fā)油流量的變化：(1)大罐液位的高低不同；(2)管線長短不同；(3)同種油品同時(shí)發(fā)油車位多少不同；(4)使用鶴管和加油槍 

　　不同。采用變頻調(diào)速器和流量計(jì)通過軟件實(shí)現(xiàn)流速的閉環(huán)調(diào)節(jié)。根據(jù)流量計(jì)的流速信號調(diào)節(jié)管道泵的轉(zhuǎn)速CONTROLENGINEERINGChina版權(quán)所有，從而調(diào)節(jié)發(fā)油流速。 

　　b.精確定量控制 

　　使用變頻器和電液閥配合，可在發(fā)油結(jié)束前的定量關(guān)閉過程中提前關(guān)閉電液閥，同時(shí)降低管道泵的轉(zhuǎn)速以減小流量。當(dāng)達(dá)到定量數(shù)量(有一微小的提前量)時(shí)快速關(guān)斷電液閥并停泵，實(shí)現(xiàn)1～2L的定量控制。
