智能水表及基本結構原理:
智(zhi)能(neng)(neng)水(shui)(shui)表(biao)是(shi)一(yi)種利用(yong)(yong)(yong)現(xian)代微電(dian)子(zi)技(ji)術(shu)(shu)、現(xian)代傳感技(ji)術(shu)(shu)、智(zhi)能(neng)(neng)IC卡技(ji)術(shu)(shu)對(dui)(dui)用(yong)(yong)(yong)水(shui)(shui)量(liang)(liang)進(jin)(jin)(jin)行(xing)計量(liang)(liang)并(bing)進(jin)(jin)(jin)行(xing)用(yong)(yong)(yong)水(shui)(shui)數(shu)據(ju)傳遞及結算(suan)交(jiao)(jiao)易的(de)(de)新(xin)型水(shui)(shui)表(biao)。這與傳統(tong)水(shui)(shui)表(biao)一(yi)般只(zhi)具(ju)有流(liu)量(liang)(liang)采集和機(ji)械指針(zhen)顯示(shi)用(yong)(yong)(yong)水(shui)(shui)量(liang)(liang)的(de)(de)功能(neng)(neng)相比,是(shi)一(yi)個很大的(de)(de)進(jin)(jin)(jin)步。智(zhi)能(neng)(neng)智(zhi)能(neng)(neng)水(shui)(shui)表(biao)除了可(ke)對(dui)(dui)用(yong)(yong)(yong)水(shui)(shui)量(liang)(liang)進(jin)(jin)(jin)行(xing)記錄(lu)和電(dian)子(zi)顯示(shi)外,還(huan)可(ke)以(yi)按照約定(ding)對(dui)(dui)用(yong)(yong)(yong)水(shui)(shui)量(liang)(liang)自(zi)(zi)動進(jin)(jin)(jin)行(xing)控制,并(bing)且自(zi)(zi)動完成階梯水(shui)(shui)價的(de)(de)水(shui)(shui)費計算(suan),同時可(ke)以(yi)進(jin)(jin)(jin)行(xing)用(yong)(yong)(yong)水(shui)(shui)數(shu)據(ju)存儲(chu)的(de)(de)功能(neng)(neng)。由于其數(shu)據(ju)傳遞和交(jiao)(jiao)易結算(suan)通(tong)過IC卡進(jin)(jin)(jin)行(xing),因而可(ke)以(yi)實現(xian)由工作(zuo)人員上門操表(biao)收費到(dao)用(yong)(yong)(yong)戶自(zi)(zi)己去營業(ye)所(suo)交(jiao)(jiao)費的(de)(de)轉變。IC卡交(jiao)(jiao)易系統(tong)還(huan)具(ju)有交(jiao)(jiao)易方便(bian),計算(suan)準確,可(ke)利用(yong)(yong)(yong)銀行(xing)進(jin)(jin)(jin)行(xing)結算(suan)的(de)(de)特點。
智能水表的基本結構原理:
萬力水表提示(shi)(shi)(shi):智能(neng)(neng)水(shui)表(biao)(biao)的(de)(de)外觀與一般水(shui)表(biao)(biao)的(de)(de)外觀基本(ben)相(xiang)似(si),其安裝過(guo)(guo)程也基本(ben)相(xiang)同。智能(neng)(neng)水(shui)表(biao)(biao)的(de)(de)使(shi)用(yong)(yong)很(hen)簡單,從用(yong)(yong)戶的(de)(de)角度看,就時(shi)把IC卡(ka)(ka)卡(ka)(ka)片(pian)向水(shui)表(biao)(biao)里插(cha)一下(xia)。智能(neng)(neng)水(shui)表(biao)(biao)的(de)(de)工作過(guo)(guo)程一般如下(xia):將(jiang)含有金(jin)額(e)的(de)(de)IC卡(ka)(ka)片(pian)插(cha)入水(shui)表(biao)(biao)中的(de)(de)IC卡(ka)(ka)讀寫器,經(jing)(jing)微(wei)機(ji)(ji)模塊(kuai)(kuai)識別和下(xia)載金(jin)額(e)后,閥門(men)(men)開(kai)(kai)啟,用(yong)(yong)戶可以正常用(yong)(yong)水(shui)。當(dang)用(yong)(yong)戶用(yong)(yong)水(shui)時(shi),水(shui)量(liang)采集裝置開(kai)(kai)始對用(yong)(yong)水(shui)量(liang)進行(xing)(xing)采集,并(bing)轉(zhuan)換成(cheng)所(suo)需(xu)的(de)(de)電(dian)子信號供(gong)給微(wei)機(ji)(ji)模塊(kuai)(kuai)進行(xing)(xing)計量(liang),并(bing)在(zai)LCD顯示(shi)(shi)(shi)模塊(kuai)(kuai)上(shang)顯示(shi)(shi)(shi)出來。當(dang)用(yong)(yong)戶的(de)(de)用(yong)(yong)水(shui)金(jin)額(e)下(xia)降到一定數(shu)值時(shi),微(wei)機(ji)(ji)模塊(kuai)(kuai)進行(xing)(xing)聲音報(bao)警,提示(shi)(shi)(shi)用(yong)(yong)戶應(ying)該(gai)去持卡(ka)(ka)交(jiao)(jiao)費(fei)購(gou)水(shui)。如超過(guo)(guo)用(yong)(yong)水(shui)金(jin)額(e),則(ze)微(wei)機(ji)(ji)模塊(kuai)(kuai)會自動將(jiang)電(dian)控閥門(men)(men)關閉(bi),切(qie)斷供(gong)水(shui)。直至用(yong)(yong)戶插(cha)入已經(jing)(jing)交(jiao)(jiao)費(fei)的(de)(de)IC卡(ka)(ka)片(pian)重新開(kai)(kai)始開(kai)(kai)啟閥門(men)(men)進行(xing)(xing)供(gong)水(shui)。
