1、全自動(dòng)洗衣機(jī)的PLC控制系統(tǒng)設(shè)計(jì)摘要隨著社會(huì)經(jīng)濟(jì)的發(fā)展和科學(xué)技術(shù)水平的提高，家用電器全自動(dòng)化成為必然的發(fā)展趨勢(shì)。全自動(dòng)洗衣機(jī)的產(chǎn)生極大的方便了人們的生活。經(jīng)過(guò)幾年的平穩(wěn)發(fā)展，國(guó)產(chǎn)洗衣機(jī)無(wú)論在質(zhì)量上還是功能上都與世界領(lǐng)先水平同步?？v觀洗衣機(jī)市場(chǎng)，高效節(jié)能、省水、省電、環(huán)保型洗衣機(jī)一直在市場(chǎng)上占主導(dǎo)地位。根據(jù)全自動(dòng)洗衣機(jī)的工作原理,可利用編程控制器PLC實(shí)現(xiàn)控制。PLC的優(yōu)點(diǎn)是：可靠性高，耗電少，適應(yīng)性強(qiáng)，運(yùn)行速度快，壽命長(zhǎng)等，為了進(jìn)一步提高全自動(dòng)洗衣機(jī)的功能和性能，避免傳統(tǒng)控制的一些弊端，因此人們就提出了
2、用PLC來(lái)控制全自動(dòng)洗衣機(jī)這個(gè)課題。全自動(dòng)洗衣機(jī)控制系統(tǒng)利用了西門(mén)子S7-200系列PLC的特點(diǎn),對(duì)按鈕,電磁閥,開(kāi)關(guān)等其他一些輸入/輸出點(diǎn)進(jìn)行控制,實(shí)現(xiàn)了洗衣機(jī)洗衣過(guò)程的自動(dòng)化。由于每遍的洗滌,排水,脫水的時(shí)間由PLC內(nèi)計(jì)數(shù)器控制,所以只要改變計(jì)數(shù)器參數(shù)就可以改變時(shí)間?？梢园焉厦嬖O(shè)定的程序時(shí)間定下來(lái),作為固定程序使用,也可以根據(jù)衣物的質(zhì)地,數(shù)量及油污的程度來(lái)編程。該論文就怎樣利用PLC來(lái)控制全自動(dòng)洗衣機(jī)進(jìn)行了調(diào)查，對(duì)其中軟件設(shè)計(jì)、硬件設(shè)計(jì)等問(wèn)題進(jìn)行了分析和研究實(shí)現(xiàn)全自動(dòng)洗衣機(jī)的正常運(yùn)行和強(qiáng)制性停止功能
