認識 在(zai)了(le)解壓(ya)阻式力(li)(li)傳(chuan)感(gan)器(qi)時(shi),我們首先認識一(yi)(yi)下電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)這(zhe)(zhe)種(zhong)元件(jian)(jian)。電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)是一(yi)(yi)種(zhong)將被測件(jian)(jian)上(shang)的(de)(de)(de)應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)(bian)(bian)化(hua)轉(zhuan)換成(cheng)為一(yi)(yi)種(zhong)電(dian)信(xin)號的(de)(de)(de)敏(min)感(gan)器(qi)件(jian)(jian)。它是壓(ya)阻式應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)傳(chuan)感(gan)器(qi)的(de)(de)(de)主要組成(cheng)部分(fen)之一(yi)(yi)。電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)應(ying)用(yong)多(duo)的(de)(de)(de)是金(jin)屬(shu)(shu)電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)和半導體應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)兩(liang)種(zhong)。金(jin)屬(shu)(shu)電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)又有絲狀應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)和金(jin)屬(shu)(shu)箔狀應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)兩(liang)種(zhong)。通(tong)常是將應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)通(tong)過特殊的(de)(de)(de)粘(zhan)和劑緊密的(de)(de)(de)粘(zhan)合(he)在(zai)產生(sheng)(sheng)力(li)(li)學應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)基體上(shang),當基體受力(li)(li)發生(sheng)(sheng)應(ying)力(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)化(hua)時(shi),電(dian)阻應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)也一(yi)(yi)起產生(sheng)(sheng)形變(bian)(bian)(bian)(bian)(bian)(bian),使(shi)應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)的(de)(de)(de)阻值發生(sheng)(sheng)改變(bian)(bian)(bian)(bian)(bian)(bian),從而(er)使(shi)加在(zai)電(dian)阻上(shang)的(de)(de)(de)電(dian)壓(ya)發生(sheng)(sheng)變(bian)(bian)(bian)(bian)(bian)(bian)化(hua)。這(zhe)(zhe)種(zhong)應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)在(zai)受力(li)(li)時(shi)產生(sheng)(sheng)的(de)(de)(de)阻值變(bian)(bian)(bian)(bian)(bian)(bian)化(hua)通(tong)常較小,一(yi)(yi)般這(zhe)(zhe)種(zhong)應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)片(pian)(pian)都組成(cheng)應(ying)變(bian)(bian)(bian)(bian)(bian)(bian)電(dian)橋,并通(tong)過后續的(de)(de)(de)儀表放大(da)器(qi)進行放大(da),再傳(chuan)輸給處(chu)理電(dian)路(通(tong)常是A/D轉(zhuan)換和CPU)顯(xian)示(shi)或執(zhi)行機構。 經過對(dui)現場信(xin)號多次模(mo)型分(fen)析,采用信(xin)號自(zi)動(dong)分(fen)段(duan)(duan)技術與模(mo)型識別(bie)技術從而(er)能有效的(de)(de)克服壓力波動(dong)等各種(zhong)干擾,提高壓力開關的(de)(de)可(ke)(ke)靠(kao)性(xing)。信(xin)號自(zi)動(dong)分(fen)段(duan)(duan)方法的(de)(de)基本原理是選(xuan)用一(yi)個(ge)固定(ding)的(de)(de)窗(chuang)選(xuan)取(qu)平(ping)穩運行的(de)(de)信(xin)號作(zuo)為參考段(duan)(duan),不斷與當前(qian)信(xin)號作(zuo)比較,非(fei)平(ping)穩性(xing)(如上站停泵引起的(de)(de)信(xin)號特性(xing)的(de)(de)變(bian)(bian)化)可(ke)(ke)以由不同段(duan)(duan)之間的(de)(de)過程統(tong)計特性(xing)和頻譜性(xing)的(de)(de)改變(bian)(bian)顯示出來。一(yi)般(ban)根(gen)據幾種(zhong)判(pan)據,當判(pan)據大(da)于(yu)一(yi)定(ding)的(de)(de)閾(yu)值或(huo)當前(qian)段(duan)(duan)低(di)于(yu)設定(ding)值時,就認為信(xin)號進入了另一(yi)段(duan)(duan)(異常(chang)段(duan)(duan))。
