簡介：可編程序控制器是專門為工業(yè)控制設(shè)計的通用自動控制裝置。它將計算機(jī)技術(shù)、自動控制技術(shù)和通訊技術(shù)融為一體，成為實現(xiàn)單機(jī)、車間、工廠自動化的核心設(shè)備。近年來我國經(jīng)濟(jì)和科學(xué)技術(shù)的高速發(fā)展，為我國郵政生產(chǎn)現(xiàn)代化提供了堅實的物質(zhì)基礎(chǔ)和可靠的技術(shù)保證。為了徹底改變過去人力搬運的郵件存儲及分揀開拆狀態(tài)，濟(jì)南郵區(qū)中心局投資與貴陽普天集團(tuán)合作上馬安裝了推式懸掛包貯存開拆系統(tǒng)，使郵件處理中心的郵袋搬運、存儲及開拆工作進(jìn)入一個嶄新的大型化、自動化、集約化的時代。為完成技術(shù)要求，選用松下電工株氏會社FPLOSH這個在工業(yè)中廣泛應(yīng)用的PLC為電控系統(tǒng)的核心，并配以人機(jī)鍵盤操作界面參加控制，對系統(tǒng)各個設(shè)備自動化運行狀態(tài)實時監(jiān)控。本文選擇“PLC在推式懸掛輸送系統(tǒng)中的應(yīng)用”作為論文題目，旨在闡述如何將可編程序控制器自動控制技術(shù)和通訊技術(shù)與郵政生產(chǎn)相結(jié)合，解決企業(yè)生產(chǎn)的實際應(yīng)用問題。我是濟(jì)南郵區(qū)中心局的一名設(shè)備技術(shù)人員，參與了該系統(tǒng)的設(shè)計和安裝工程，通過這篇論文對這一階段的工作進(jìn)行一下總結(jié)，同時也是再提高和再學(xué)習(xí)。

簡介：棉花打包機(jī)作為棉花加工企業(yè)中的一種重要設(shè)備，其作用和地位都是不可替代的。而控制系統(tǒng)對棉花打包機(jī)能否正常生產(chǎn)起著決定性的作用。自從我國實行棉花質(zhì)量檢驗體質(zhì)改革以來，國內(nèi)許多棉花打包機(jī)的控制系統(tǒng)已經(jīng)難以滿足現(xiàn)實生產(chǎn)的要求，進(jìn)行更新?lián)Q代勢在必行。本課題以下項式雙箱液壓打包機(jī)控制系統(tǒng)的電氣化改造為背景，通過對棉花打包的生產(chǎn)工藝、打包機(jī)的結(jié)構(gòu)組成以及生產(chǎn)環(huán)境進(jìn)行調(diào)研和分析，提出了應(yīng)用可編程序控制器PLC為主要控制單元的控制系統(tǒng)來替代原有繼電接觸控制系統(tǒng)的方案。以PLC控制系統(tǒng)的實現(xiàn)為研究重點，仔細(xì)分析了棉花打包機(jī)的控制要求，設(shè)計了一套基于PLC的控制系統(tǒng)，完成了系統(tǒng)的硬件設(shè)計、軟件程序設(shè)計以及人機(jī)界面監(jiān)控系統(tǒng)的設(shè)計。分析了對棉花打包機(jī)實現(xiàn)棉包重量控制與調(diào)節(jié)的方法，采用壓力計量的方式對棉包重量進(jìn)行控制。采用壓力變送器采集到踩棉預(yù)壓壓力信號，經(jīng)過AD轉(zhuǎn)換之后得到的數(shù)字量與PLC內(nèi)部設(shè)定值進(jìn)行比較，確定棉包重量是否到達(dá)要求。此外，還考慮了回潮率對棉包重量的影響，對棉包的回潮率進(jìn)行檢測，并根據(jù)檢測結(jié)果對棉包重量進(jìn)行調(diào)節(jié)。論文結(jié)合機(jī)電一體化系統(tǒng)可靠性的相關(guān)理論，分析了影響棉花打包機(jī)控制系統(tǒng)可靠性的因素。根據(jù)分析結(jié)果將影響棉花打包機(jī)控制系統(tǒng)可靠性的主要因素分為現(xiàn)場干擾和系統(tǒng)故障這兩類。結(jié)合打包機(jī)的現(xiàn)場工作條件提出了一系列提高棉花打包機(jī)控制系統(tǒng)可靠性的相關(guān)措施。
