ic卡燃氣表工作原理

首先由IC卡從燃氣銷售部門(men)購(gou)(gou)(gou)入(ru)一(yi)個(ge)(ge)預購(gou)(gou)(gou)氣量(liang)(liang)，然后經過(guo)(guo)密碼校驗后寫入(ru)燃氣表內相(xiang)應存儲區(qu)。通(tong)過(guo)(guo)干(gan)簧(huang)管來控制用(yong)(yong)(yong)氣情況,用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)氣時(shi)，閥門(men)打開，干(gan)簧(huang)管每旋轉一(yi)圈，產生一(yi)個(ge)(ge)減數電脈沖，預購(gou)(gou)(gou)氣量(liang)(liang)自動減去(qu)一(yi)個(ge)(ge)基本計(ji)量(liang)(liang)單(dan)位(0.01升)。當預購(gou)(gou)(gou)氣量(liang)(liang)到(dao)達設定值時(shi)，峰鳴器報警(jing)，并顯示預購(gou)(gou)(gou)氣量(liang)(liang)不足代碼03，關(guan)(guan)閥一(yi)次，提(ti)示用(yong)(yong)(yong)戶(hu)購(gou)(gou)(gou)氣。同時(shi)根據相(xiang)關(guan)(guan)條件決定氣閥的開和(he)關(guan)(guan)來控制用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)氣，并對用(yong)(yong)(yong)氣量(liang)(liang)進行累積。

ic卡智能燃氣表功能

(1)開機檢測功能(neng):系統在斷電復(fu)位后,應能(neng)根據上次保(bao)存的數(shu)據，以(yi)及(ji)當前的狀態(如(ru)電壓、磁場等(deng))，決定是否開閥。

(2)掉電(dian)數據存(cun)儲功(gong)能:在外(wai)置電(dian)源供電(dian)突然停(ting)止的情況下(xia)應完(wan)整無誤的將一些重(zhong)要數據保存(cun)下(xia)來,以便(bian)系(xi)統復位后(hou),能重(zhong)新(xin)調入(ru)重(zhong)要數據。

(3)低(di)電(dian)(dian)(dian)(dian)壓(ya)檢測(ce)(ce)功能:由于本燃氣表是(shi)用(yong)電(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian),故電(dian)(dian)(dian)(dian)壓(ya)檢測(ce)(ce)功能必不可少,當電(dian)(dian)(dian)(dian)壓(ya)下降至某一(yi)值(zhi)時,系統應能感知,并提(ti)示(shi)用(yong)戶更換電(dian)(dian)(dian)(dian)池;系統自(zi)動關閉閥門(men)。

(4)強磁(ci)場干擾(rao)檢測功能:當(dang)外界有強磁(ci)場干擾(rao),企圖(tu)影響燃氣控制器正確計量時,系(xi)統應能自(zi)動關閉閥門。

(5)電(dian)關閥功能(neng):受控(kong)閥門在外置電(dian)源供電(dian)突然停止(zhi)的(de)瞬間應有充分(fen)的(de)電(dian)能(neng)關閉閥門。

(6)報警(jing)(jing)顯示(shi)(shi)功能:當剩余氣量不足、欠(qian)壓和(he)有故障(zhang)時(shi),應能聲(sheng)音(yin)報警(jing)(jing),屏幕顯示(shi)(shi)。

(7)讀(du)寫(xie)IC卡功能:應能正確無誤的讀(du)寫(xie)IC卡。

(8)正確計量功(gong)能:準確計量,并且(qie)具有累積使(shi)用量統(tong)計功(gong)能。
