西門子MP277-10操作面板按鍵全失靈解決;公(gong)司是(shi)專業(ye)從事西門子觸(chu)摸屏,工(gong)(gong)業(ye)控制(zhi)化(hua)系統維修(xiu)領域(yu)內的(de)設備(bei)為主,涉及行業(ye)之(zhi)廣泛,如:機(ji)械制(zhi)造,磨具加工(gong)(gong),液壓,光伏能(neng)源、半導體、紡(fang)織(zhi)、線纜電器制(zhi)造,能(neng)源裝備(bei),塑料、醫療(liao)、環保、冶金、造紙、汽車電子、鋼鐵、化(hua)工(gong)(gong)、鍋爐控制(zhi)、煉油、石(shi)化(hua)、光纖、橡膠、能(neng)源發電、裝飾材料,鋁板等行業(ye)
西門子MP277-10操作面板按鍵全失靈解決;這(zhe)是(shi)和(he)人(ren)手接觸較(jiao)多的(de)(de)(de)地(di)方,也(ye)是(shi)容(rong)易出(chu)問題的(de)(de)(de)表面層,一(yi)般(ban)這(zhe)類型的(de)(de)(de)故障是(shi)由于用(yong)戶方人(ren)員(yuan)比較(jiao)粗魯(lu)動作引起的(de)(de)(de),也(ye)有(you)由于運輸等不小(xiao)心(xin)造(zao)成(cheng),結果一(yi)般(ban)都是(shi)破(po)碎,偶爾(er)也(ye)可能發(fa)生(sheng)里邊(bian)電阻(zu)等器件斷裂(lie),這(zhe)種故障只有(you)換觸摸(mo)玻(bo)璃,因為各(ge)種廠家生(sheng)產時候規范標準(zhun)不同,所以往(wang)往(wang)更換的(de)(de)(de)時候存在“開(kai)模”這(zhe)樣的(de)(de)(de)過程,一(yi)旦開(kai)好了模,那么觸摸(mo)屏(ping)維修是(shi)很簡單的(de)(de)(de)事(shi)情了,就是(shi)更換了。
現在的(de)(de)許多觸(chu)摸屏(ping)多具有瞬間停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)自(zi)啟動功(gong)能(neng),對(dui)于數毫秒(miao)以內的(de)(de)瞬間停(ting)(ting)(ting)電(dian)(dian)(dian)(dian),觸(chu)摸屏(ping) 的(de)(de)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)路(lu)工作不(bu)會受到(dao)影響(xiang),仍(reng)然可以正常工作。但(dan)如(ru)果瞬間停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)達到(dao)數10ms以上(shang)時(shi)(shi), 這時(shi)(shi)不(bu)僅(jin)會使控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)路(lu)出現誤動作,主(zhu)電(dian)(dian)(dian)(dian)路(lu)也不(bu)能(neng)提供供電(dian)(dian)(dian)(dian),觸(chu)摸屏(ping)將會停(ting)(ting)(ting)止工作。 (2)處理(li)方法 對(dui)于瞬時(shi)(shi)停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)后要求調速(su)系(xi)統(tong)繼續(xu)工作的(de)(de),則應(ying)(ying)在系(xi)統(tong)設計時(shi)(shi)選擇具有瞬間停(ting)(ting)(ting)電(dian)(dian)(dian)(dian) 功(gong)能(neng)的(de)(de)觸(chu)摸屏(ping),外部控(kong)制(zhi)(zhi)回路(lu)應(ying)(ying)設有瞬間停(ting)(ting)(ting)機補償方式(shi)與測速(su)單(dan)元。一旦電(dian)(dian)(dian)(dian)源恢復以后, 通(tong)過速(su)度追蹤與測速(su)電(dian)(dian)(dian)(dian)動機檢(jian)測的(de)(de)信號來防止在系(xi)統(tong)加速(su)中的(de)(de)過電(dian)(dian)(dian)(dian)流出現。 (3)需要說明的(de)(de)問題 對(dui)于必(bi)須要求連接運行的(de)(de)調速(su)系(xi)統(tong),應(ying)(ying)考慮給觸(chu)摸屏(ping)設置(zhi)自(zi)動切換(huan)的(de)(de)不(bu)停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源 裝置(zhi)系(xi)統(tong)。
