1756-L1/ABPLC模塊
在控制電路中,輸入PLC的控制信號為32點,包括司機指令信號(如司機控制器、各琴鍵開關(guān)、按鈕開關(guān)等元件的觸點信號)和機車狀態(tài)信號(如溫度繼電器、壓力繼電器、柴油機轉(zhuǎn)速信號和機車速度信號等)。PLC輸出的控制信號點數(shù)為32點,包括動作執(zhí)行元件(各接觸器線圈、電空閥及去電子調(diào)速箱的控制信號)。
系統(tǒng)的核心部分,采用的是日本三菱公司的FX2—80MR—D型PLC。該機型為整體式PLC機,結(jié)構(gòu)緊湊、體積小、重量輕,具有很強的抗*力和負載能力。而且FX2系列PLC機是三菱公司90年代初推出的產(chǎn)品,它的大的特點是在小型機上實現(xiàn)大型機的功能,可與計算機自由聯(lián)接。(性能參數(shù)見表1)該機型有40個輸入點和40個輸出點。不帶擴展模塊,*系統(tǒng)的要求。機車速度和柴油機轉(zhuǎn)速傳感器采用了目前鐵路機車通用的數(shù)字式測速傳感器。
