PLC的六個應用領域
? ? ? 目前,PLC在國內(nèi)外已廣泛應用于鋼鐵、石油、化工、電力、建材、機械制造、汽車、輕紡、交通運輸、環(huán)保及文化娛樂等各個行業(yè),使用情況大致可歸納為如下幾類。
? 1開關量的邏輯控制
? 這是PLC最基本、最廣泛的應用領域,它取代傳統(tǒng)的繼電器電路,實現(xiàn)邏輯控制、順序控制,既可用于單臺設備的控制,也可用于多機群控及自動化流水線。如注塑機、印刷機、訂書機械、組合機床、磨床、包裝生產(chǎn)線、電鍍流水線等。
? 2模擬量控制
? 在工業(yè)生產(chǎn)過程當中,有許多連續(xù)變化的量,如溫度、壓力、流量、液位和速度等都是模擬量。為了使可編程控制器處理模擬量,必須實現(xiàn)模擬量(Analog)和數(shù)字量(Digital)之間的A/D轉(zhuǎn)換及D/A轉(zhuǎn)換。PLC廠家都生產(chǎn)配套的A/D和D/A轉(zhuǎn)換模塊,使可編程控制器用于模擬量控制。
? 3運動控制?
? PLC可以用于圓周運動或直線運動的控制。從控制機構配置來說,早期直接用于開關量I/O模塊連接位置傳感器和執(zhí)行機構,現(xiàn)在一般使用專用的運動控制模塊。如可驅(qū)動步進電機或伺服電機的單軸或多軸位置控制模塊。世界上各主要PLC廠家的產(chǎn)品幾乎都有運動控制功能,廣泛用于各種機械、機床、機器人、電梯等場合。
? 4過程控制
? 過程控制是指對溫度、壓力、流量等模擬量的閉環(huán)控制。作為工業(yè)控制計算機,PLC能編制各種各樣的控制算法程序,完成閉環(huán)控制。PID調(diào)節(jié)是一般閉環(huán)控制系統(tǒng)中用得較多的調(diào)節(jié)方法。大中型PLC都有PID模塊,目前許多小型PLC也具有此功能模塊。PID處理一般是運行專用的PID子程序。過程控制在冶金、化工、熱處理、鍋爐控制等場合有非常廣泛的應用。
? 5數(shù)據(jù)處理
? 現(xiàn)代PLC具有數(shù)學運算(含矩陣運算、函數(shù)運算、邏輯運算)、數(shù)據(jù)傳送、數(shù)據(jù)轉(zhuǎn)換、排序、查表、位操作等功能,可以完成數(shù)據(jù)的采集、分析及處理。這些數(shù)據(jù)可以與存儲在存儲器中的參考值比較,完成一定的控制操作,也可以利用通信功能傳送到別的智能裝置,或?qū)⑺鼈兇蛴≈票?。?shù)據(jù)處理一般用于大型控制系統(tǒng),如無人控制的柔性制造系統(tǒng);也可用于過程控制系統(tǒng),如造紙、冶金、食品工業(yè)中的一些大型控制系統(tǒng)。
? 6通信及聯(lián)網(wǎng)
? PLC通信含PLC間的通信及PLC與其它智能設備間的通信。隨著計算機控制的發(fā)展,工廠自動化網(wǎng)絡發(fā)展得很快,各PLC廠商都十分重視PLC的通信功能,紛紛推出各自的網(wǎng)絡系統(tǒng)。新近生產(chǎn)的PLC都具有通信接口,通信非常方便.
