PLC在冰蓄冷中央空調(diào)系統(tǒng)控制中的應(yīng)用-中文翻譯

1、中文文獻(xiàn)PLC 在冰蓄冷中央空調(diào)系統(tǒng)控制中的應(yīng)用1 引言 在 PLC 被開(kāi)發(fā)出來(lái)的三十年里，它經(jīng)過(guò)不斷地發(fā)展，已經(jīng)能結(jié)合模擬 I/O，網(wǎng)絡(luò)通信以及采用新的編程標(biāo)準(zhǔn)如 IEC 61131-3。然而，工程師們只需利用數(shù)字 I/O 和少量的模擬I/O 數(shù)以及簡(jiǎn)單的編程技巧就可開(kāi)發(fā)出 80%的工業(yè)應(yīng)用. PLC 已經(jīng)廣泛的應(yīng)用在所有的工業(yè)部門。據(jù)“美國(guó)市場(chǎng)信息”的世界 PLC 以及軟件市場(chǎng)報(bào)告稱，1995 年全球 PLC 及其軟件的市場(chǎng)經(jīng)濟(jì)規(guī)模約 50 億美元5。隨著電子技術(shù)和計(jì)算機(jī)技術(shù)的發(fā)展，PLC 的功能得到大大的增強(qiáng)由于采用傳統(tǒng)的工具可以解決 80%的工業(yè)應(yīng)用，這樣就強(qiáng)。

4、PLC in the ice storage central air-conditioning system of control1 Introduction In PLC in 30 years which developed, it passes through develops unceasingly, already could unify simulates I/O, the network corresponds as well as uses new programming standard like IEC 61131-3. However, engineers only must use digital I/O and few simulations I/O number as well as simple programming skill on potential 80% industrial application. PLC has been widely used in all industrial sectors. According to "。
