用矩陣輸入方法除了要按圖6-12的硬件連接外,還必須編寫對(duì)應(yīng)的PLC程序。由于矩陣輸入的信號(hào)是分時(shí)被讀入PLC,所以讀入的輸入信號(hào)為一系列斷續(xù)的脈沖信號(hào),在使用時(shí)應(yīng)注意這個(gè)問(wèn)題。另外,應(yīng)保證輸入信號(hào)的寬度要大于Y0、Y1、Y2輪流導(dǎo)通一遍的時(shí)間,否則可能會(huì)丟失輸入信號(hào)。
3.組合輸入
對(duì)于不會(huì)同時(shí)接通的輸入信號(hào),可采用組合編碼的方式輸入。如圖6-14a所示,三個(gè)輸入信號(hào)Q1、Q2、Q3只要占用兩個(gè)輸入點(diǎn),再通過(guò)如圖6-14b所示程序的譯碼,又還原成與Q1、Q2、Q3對(duì)應(yīng)的M0、M1、M2三個(gè)信號(hào)。采用這種方法應(yīng)特別注意要保證各輸入開(kāi)關(guān)信號(hào)不會(huì)同時(shí)接通。

?①PLC的編程,從梯形圖來(lái)看,其根本點(diǎn)是找出系統(tǒng)中符合控制要求的各個(gè)輸出的工作條件,這些條件又總是用編程元件按一定的邏輯關(guān)系進(jìn)行組合來(lái)實(shí)現(xiàn)的。 ②梯形圖的基本模式為啟—?!k娐?。每個(gè)啟—保—停電路一般只針對(duì)一個(gè)輸出,這個(gè)輸出可以是系統(tǒng)的實(shí)際輸出,也可以是中間變量。 ③梯形圖編程中有一些約定俗成的基本環(huán)節(jié),它們都有一定的功能,可以像擺積木一樣在許多地方應(yīng)用。 160-BA03NPS1P

空分選用的是離心式壓縮機(jī),離心壓縮機(jī)工作效率高,在正常工況條件下運(yùn)行平穩(wěn),壓縮氣流無(wú)脈動(dòng),對(duì)其所輸送介質(zhì)的壓力、流量、溫度變化的敏感性相對(duì)較大,容易發(fā)生喘振。發(fā)生喘振時(shí)流量大幅波動(dòng),機(jī)組劇烈振動(dòng),如不及時(shí)采取措施加以控制,會(huì)使壓縮機(jī)轉(zhuǎn)子和靜子經(jīng)受交變應(yīng)力作用而斷裂;使較間壓力失常而引起強(qiáng)烈振動(dòng),導(dǎo)致密封及推力軸承損壞;使運(yùn)動(dòng)元件和靜止元件相碰,造成嚴(yán)重事故。所以應(yīng)盡力防止壓縮機(jī)進(jìn)入喘振工況。喘振現(xiàn)
