待機(jī)、停機(jī):系統(tǒng)正常運(yùn)行時(shí),若I20濃水箱低液位開關(guān)閉合,延時(shí)30S后停止Q6增壓泵和Q5高壓泵,然后開Q2濃水排放電動(dòng)閥和Q1沖洗電動(dòng)閥,然后開啟Q7沖洗泵,進(jìn)行停機(jī)沖洗,沖洗15Min后先關(guān)Q2濃水排放閥,然后關(guān)閉Q1沖洗電動(dòng)閥,后關(guān)Q7,沖洗泵,系統(tǒng)進(jìn)入待機(jī)狀態(tài),當(dāng)I21濃水箱高液位開關(guān)閉合時(shí),系統(tǒng)自動(dòng)進(jìn)入開機(jī)沖洗,實(shí)現(xiàn)裝置的自動(dòng)循環(huán)運(yùn)行,程序如圖10。
5)報(bào)警:當(dāng)高壓泵入口壓力低,I18閉合時(shí),為保護(hù)高壓泵,停止高壓泵運(yùn)行,并顯示報(bào)警Q3,報(bào)警必須經(jīng)I8復(fù)位后才可再啟動(dòng)高壓泵,為避免頻繁啟動(dòng),報(bào)警出現(xiàn)1Min后才可再次啟動(dòng)高壓泵;當(dāng)高壓泵出口壓力過高,I19閉合時(shí),為保護(hù)超濾膜,停止高壓泵運(yùn)行,并顯示高壓報(bào)警Q4,報(bào)警必須經(jīng)過復(fù)位后才可再次啟動(dòng)高壓泵,為避免頻繁啟動(dòng),報(bào)警出現(xiàn)1Min后才可再次啟動(dòng)高壓泵,程序如圖11。
6)阻垢劑計(jì)量泵與高壓泵聯(lián)鎖啟停,絮凝劑計(jì)量泵、加酸計(jì)量泵與增壓泵聯(lián)鎖啟停,以上連鎖都是通過外部接觸器輔助觸點(diǎn)控制。
5、離線仿真與在線測(cè)試
西門子LOGO!編程軟件集成離線仿真功能,在程序下載前進(jìn)行仿真測(cè)試能避免許多不必要的問題出現(xiàn),仿真時(shí)可以進(jìn)行斷電測(cè)試,提高了系統(tǒng)的安全性。測(cè)試完畢后,將程序下載到LOGO!進(jìn)行在線測(cè)試,如圖12至圖13所示,LOGO!狀態(tài)如圖14至圖15。
6、應(yīng)用實(shí)例
下面圖16至圖19是本公司近調(diào)試的一個(gè)應(yīng)用實(shí)例,控制是一樣的,只是比本試用項(xiàng)目多了模擬量部分。
四、應(yīng)用體會(huì)
1、通過實(shí)際編程,應(yīng)用指令后才發(fā)現(xiàn)了LOGO!的強(qiáng)大,甚至有的計(jì)時(shí)器比step7還要方便,LOGO!完全替代了大量的繼電器電路,節(jié)約了控制柜空間,減少接線,從而降低故障發(fā)生率。
2、靈活的編程方法,上手快,編程語(yǔ)言豐富,功能齊全,滿足了不同的需求,自帶顯示面板是個(gè)亮點(diǎn),可以不用PC監(jiān)控查看內(nèi)部程序,可以進(jìn)行故障診斷。
3、高性價(jià)比,低廉的價(jià)格更具競(jìng)爭(zhēng)力,適合在小型系統(tǒng)中開發(fā)使用。近幾年我國(guó)食品機(jī)械發(fā)展迅速,但仍然無法滿足龐大的食品加工需求量。加之各地政府部門非常重視農(nóng)產(chǎn)品加工業(yè)和食品加工行業(yè)failure, emergency shutdown and garage failure; Semi automatic is to operate the buttons on the PLC control panel, and PLC realizes automatic logic control; Fully automatic means that the access command is given by the computer and the task is executed by the PLC (it is required to be equipped with "operator"). Among them, manual mode is the highest priority, while semi-automatic or full-automatic mode is used for normal vehicle entry and exit processing, in which semi-automatic mode has higher priority than full-automatic mode. When the computer is offline, the PLC control panel can complete all access vehicle operations, and this design requires that manual, semi-automatic and full-automatic must be interlocked. PLC control system design PLC is the core of garage control system. Its operation is roughly divided into three categories: Operation Based on fault diagnosis and treatment; Contact the data I / O operation of site conditions; Execute user programs
