摘 要 : 根據(jù)全自動洗衣機的工作原理,利用可編程控制器 PLC實現(xiàn)控制,說明了 PLC控制的原理方法,特點及控制洗衣機的特色。通過本系統(tǒng)的設(shè)計,對歐姆龍 CJ1M系列 PLC的特點有了深入的理解。全自動洗衣機控制系統(tǒng)利用了歐姆龍 CJ1M系列 PLC的特點,對按鈕,電磁閥,開關(guān)等其它一些輸入 /輸出點進行控制,實現(xiàn)了洗衣機洗衣過程的自動化,并實現(xiàn)了多臺控制。由于每遍的洗滌,排水,脫水的時間由 PLC內(nèi)計數(shù)器控制,所以只要改變計數(shù)器參數(shù)就可以改變時間。可以把上面設(shè)定的程序時間定下來,作為固定程序使用,也可以根據(jù)衣物的質(zhì) 地,數(shù)量及臟污的程度來編程。只要稍作改變,就可以設(shè)計出諸如要多洗多甩的牛仔類衣物,輕洗輕甩的羊毛類衣物以及通用的標準洗滌程序,充分表現(xiàn)現(xiàn)代家電用品的個性。 關(guān)鍵詞:全自動洗衣機; PLC控制; CXProgrammer Abstract According to the work principle of the fullautomatic washer, make use of the programmable logical controller PLC realization control, explain the principle method of the PLC control, the special features of the characteristics and the control to the design of this system, had the thorough prehension to the characteristics of the OMRON CJ1M series PLC in fullautomatic washer control system made use of the characteristics of the OMRON CJ1M series PLC in Europe, to the button, the electromagism valve, switch etc. a little bit other importation/ output to order to carry on the control, carry out the washer to do laundry the automation of the process, and carried out many pedestals each of rinse, drain, time that dehydrate from PLC inside count the machine control, so as long as the change count the machine parameter and can change settle down procedure time that the top set, the conduct and actions fixs the procedure usage, also can according to the quality of the clothes, the degree of the quantity and dirt to weave the dist long as make the change slightly, can design such as the cowboy clothes that want to wash much to jilt much, the wool clothes and in general use standards that wash lightly to jilt lightlies wash away dirt the procedure, expressing the character of the modern electrical appliance well. Key words: fullautomatic washer PLC control。 CXProgrammer 目錄 摘要 ?????????????????????????1 目錄 ?????????????????????????3 第一章 緒論 ???????????????????????4 概論 ????????????????????????4 PLC 的定義 ????????????????????4 PLC 的特點 ??????????????????????4 高可靠性 ?????????????????????5 應(yīng)用靈活,使用方便 ???????? ????????5 面向控制過程的編程語言,容易掌握 ?????????5 PLC 的分類 ??????????????????????5 小型 PLC?????????????????????5 中型 PLC?????????????????????6 大型 PLC?????????????????????6 PLC 的主要技術(shù)指標 ??????????????????6 存儲器容量 ????????????????????6 輸入 /輸出點數(shù) ???????????????????6 掃描時間 ?????????????????????6 指令種類和數(shù)量 ??????????????????6 內(nèi)部寄存的種類和數(shù)量 ???????????????7 擴展能力 ?????????????????????7 智能模塊的種類和數(shù)量 ???????????????7 第二章 PLC 的結(jié)構(gòu) ????????????????????8 PLC 的基本結(jié)構(gòu) ?????????? ?????????8 整體式的結(jié)構(gòu) PLC??????????????????8 模塊式結(jié)構(gòu)的 PLC??????????????????8 PLC 各組成部分介紹 ?????????????????9 基本指令 ??????????????????????10 第三章 PLC 的工作原理 ??????????????????11 循環(huán)掃描技術(shù) ????????????????????11 PLC 的輸入 /輸出的響應(yīng)時間 ??????????????12 第四章 PLC 的控制系統(tǒng)設(shè) 計原則和設(shè)計步驟 ?????????14 設(shè)計原則 ??????????????????????14 設(shè)計步驟 ??????????????????????1
