PLC控制系統(tǒng)中的干擾是一個十分復(fù)雜的問題，因此在抗干擾設(shè)計中應(yīng)綜合考慮各方面的因素，合理有效地抑制抗干擾，才能夠使PLC控制系統(tǒng)正常工作。隨著PLC應(yīng)用領(lǐng)域的不斷拓寬，如何高效可靠的使用PLC也成為其發(fā)展的重要因素。21世紀(jì)，PLC會有更大的發(fā)展，產(chǎn)品的品種會更豐富、規(guī)格更齊全，通過完美的人機(jī)界面、完備的通信設(shè)備會更好地適應(yīng)各種工業(yè)控制場合的需求，PLC作為自動化控制網(wǎng)絡(luò)和國際通用網(wǎng)絡(luò)的重要組成部分，將在工業(yè)控制領(lǐng)域發(fā)揮越來越大的作用?原有系統(tǒng)裝在20多臺門機(jī)（門吊）上，目前已經(jīng)安裝了稱重數(shù)據(jù)采集系統(tǒng)（單片機(jī)開發(fā)），采用IC卡式數(shù)據(jù)傳輸方式，由于軟件構(gòu)件缺乏科學(xué)性和合理性而且數(shù)據(jù)采集錯誤的情況比較嚴(yán)重，導(dǎo)致管理軟件并未起到應(yīng)有的作用。原有系統(tǒng)數(shù)據(jù)傳輸?shù)臅r滯性和準(zhǔn)確性都需要改進(jìn)，上位機(jī)管理軟件也需要進(jìn)行相應(yīng)的更新，以達(dá)到真正的門機(jī)作業(yè)自動化管理。為了實現(xiàn)科學(xué)的、方便的管理，現(xiàn)在需要將門機(jī)稱重系統(tǒng)、風(fēng)速儀以及門機(jī)工作狀態(tài)信息數(shù)據(jù)一同實時傳到門機(jī)隊監(jiān)控中心，解決IC卡式數(shù)據(jù)傳輸方式的時滯，加強(qiáng)對門機(jī)工作的管理力度和工作過程中的事故防范能力，系統(tǒng)采用GPRS的無線數(shù)據(jù)傳輸方式，確?，F(xiàn)場和管理中心所得到的數(shù)據(jù)的一致性，在工作現(xiàn)場配備RTU-2600智能終端，以便于實時采集、傳輸數(shù)據(jù)；配備HMI-3800人機(jī)界面供門機(jī)司機(jī)進(jìn)行操作；在管理中心重新配備上位機(jī)數(shù)據(jù)管理軟件，接收現(xiàn)場工作數(shù)據(jù)，并實現(xiàn)用戶管理、曲線顯示、報表打印、歷史數(shù)據(jù)記錄等功能。
