智能水表中傳感器:
1.干(gan)(gan)簧管傳感器(qi):在機械水表中加裝干(gan)(gan)簧管和磁鐵(tie)(tie),利用干(gan)(gan)簧管的簧片在磁鐵(tie)(tie)的循環作用下(xia)循環開(kai)閉,從而輸(shu)出計量脈(mo)沖信(xin)號(hao)。
2.霍爾(er)(er)傳感(gan)器:在(zai)機械水表中加裝(zhuang)霍爾(er)(er)元件和磁(ci)鐵,構成(cheng)基于磁(ci)電(dian)轉(zhuan)換技術的傳感(gan)器,安裝(zhuang)在(zai)計(ji)數盤位(wei)上的磁(ci)鐵隨著計(ji)數轉(zhuan)盤運轉(zhuan),每(mei)經過(guo)霍爾(er)(er)元件一次(ci),即由霍爾(er)(er)元件輸出一個計(ji)數脈沖。
3.光電傳感(gan)器(qi):在機械(xie)水表的轉(zhuan)盤處安裝一(yi)個光電轉(zhuan)換(huan)器(qi),在轉(zhuan)盤上(shang)有(you)一(yi)條溝槽(cao),轉(zhuan)盤每轉(zhuan)一(yi)圈,溝槽(cao)經過(guo)光輸時轉(zhuan)換(huan)器(qi)完成一(yi)次電轉(zhuan)換(huan),輸出一(yi)個計數脈(mo)沖。
智能水表及基本結構原理:
智(zhi)能(neng)(neng)(neng)水(shui)表(biao)是一種(zhong)利用(yong)現(xian)代微(wei)電子技術(shu)、現(xian)代傳(chuan)感技術(shu)、智(zhi)能(neng)(neng)(neng)IC卡技術(shu)對(dui)用(yong)水(shui)量(liang)進(jin)(jin)(jin)行(xing)(xing)計量(liang)并(bing)進(jin)(jin)(jin)行(xing)(xing)用(yong)水(shui)數據(ju)傳(chuan)遞(di)及(ji)結算交(jiao)易(yi)的新型水(shui)表(biao)。這與傳(chuan)統(tong)(tong)水(shui)表(biao)一般(ban)只具(ju)有流量(liang)采集和(he)機械指針顯示用(yong)水(shui)量(liang)的功能(neng)(neng)(neng)相比,是一個很大的進(jin)(jin)(jin)步。智(zhi)能(neng)(neng)(neng)智(zhi)能(neng)(neng)(neng)水(shui)表(biao)除(chu)了可對(dui)用(yong)水(shui)量(liang)進(jin)(jin)(jin)行(xing)(xing)記錄和(he)電子顯示外,還(huan)可以(yi)按照約定對(dui)用(yong)水(shui)量(liang)自動進(jin)(jin)(jin)行(xing)(xing)控制,并(bing)且自動完成階(jie)梯水(shui)價的水(shui)費計算,同時可以(yi)進(jin)(jin)(jin)行(xing)(xing)用(yong)水(shui)數據(ju)存(cun)儲(chu)的功能(neng)(neng)(neng)。由于其數據(ju)傳(chuan)遞(di)和(he)交(jiao)易(yi)結算通過IC卡進(jin)(jin)(jin)行(xing)(xing),因而可以(yi)實現(xian)由工作(zuo)人(ren)員上(shang)門操(cao)表(biao)收費到用(yong)戶自己去營業所交(jiao)費的轉變。IC卡交(jiao)易(yi)系統(tong)(tong)還(huan)具(ju)有交(jiao)易(yi)方(fang)便,計算準確(que),可利用(yong)銀行(xing)(xing)進(jin)(jin)(jin)行(xing)(xing)結算的特點。
智能水表的基本結構原理:
萬力水表提示:智能水(shui)(shui)(shui)表的外觀(guan)與一(yi)般水(shui)(shui)(shui)表的外觀(guan)基本(ben)相(xiang)(xiang)似,其安(an)裝過(guo)程(cheng)也基本(ben)相(xiang)(xiang)同(tong)。智能水(shui)(shui)(shui)表的使用(yong)(yong)(yong)很簡單,從用(yong)(yong)(yong)戶(hu)的角度看,就時把IC卡(ka)卡(ka)片向水(shui)(shui)(shui)表里插(cha)(cha)一(yi)下(xia)。智能水(shui)(shui)(shui)表的工作過(guo)程(cheng)一(yi)般如下(xia):將含有金額(e)的IC卡(ka)片插(cha)(cha)入(ru)水(shui)(shui)(shui)表中的IC卡(ka)讀寫器,經微(wei)機(ji)(ji)模(mo)(mo)塊(kuai)(kuai)識(shi)別和(he)下(xia)載(zai)金額(e)后(hou),閥門(men)開(kai)啟,用(yong)(yong)(yong)戶(hu)可以(yi)正常(chang)用(yong)(yong)(yong)水(shui)(shui)(shui)。當(dang)(dang)用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)水(shui)(shui)(shui)時,水(shui)(shui)(shui)量(liang)采集(ji)裝置開(kai)始對用(yong)(yong)(yong)水(shui)(shui)(shui)量(liang)進行(xing)采集(ji),并轉換(huan)成所需的電子信號供給微(wei)機(ji)(ji)模(mo)(mo)塊(kuai)(kuai)進行(xing)計量(liang),并在LCD顯(xian)示模(mo)(mo)塊(kuai)(kuai)上顯(xian)示出來。當(dang)(dang)用(yong)(yong)(yong)戶(hu)的用(yong)(yong)(yong)水(shui)(shui)(shui)金額(e)下(xia)降到一(yi)定數值(zhi)時,微(wei)機(ji)(ji)模(mo)(mo)塊(kuai)(kuai)進行(xing)聲音報(bao)警(jing),提示用(yong)(yong)(yong)戶(hu)應該去持卡(ka)交費購水(shui)(shui)(shui)。如超過(guo)用(yong)(yong)(yong)水(shui)(shui)(shui)金額(e),則微(wei)機(ji)(ji)模(mo)(mo)塊(kuai)(kuai)會自(zi)動將電控閥門(men)關閉,切斷供水(shui)(shui)(shui)。直至用(yong)(yong)(yong)戶(hu)插(cha)(cha)入(ru)已經交費的IC卡(ka)片重新(xin)開(kai)始開(kai)啟閥門(men)進行(xing)供水(shui)(shui)(shui)。
