Hauv peb txoj kev txuas nrog thiab txuas lus thoob ntiaj teb, nws tsis yog qhov xav tsis thoob tias kev xav tau rau ntse meters tau nce. Ntse meters, raws li lub npe qhia, siv cov thev naus laus zis los ntsuas cov hluav taws xob lossis cov khoom lag luam ntau npaum li cas. Tab sis li cas cov thev naus laus zis ua haujlwm? Cov cuab yeej siv cov khoom siv no puas yog kev pheej hmoo rau peb kev noj qab haus huv lossis kev nyab xeeb? Tib neeg yuav tsum nyob hauv lawv lub tsev?
MaStrental hluav taws xob hluav taws xob tsuas yog ntes cov hluav taws xob uas tau dhau los ntawm nws txij li thaum lub ntsuas yog nyeem kawg. Nyob rau hauv kev sib piv, ntse meters muab ob cov kev pabcuam tseem ceeb: tshwj xeeb koj muab hluav taws xob ntau tshaj li ua ntej (lwm qhov yog thaum thiab cov ntaub ntawv faib hluav taws xob ntau dua li cov ntaub ntawv faib tawm. Tsis zoo li cov neeg siv hluav taws xob, ntse meters tuaj yeem xa cov ntaub ntawv nyob deb, uas txhais tau tias tsis muaj leej twg yuav tsum tau mus rau koj qhov chaw nyob ntawm tus kheej.
Txawm hais tias txhua cov thev naus laus zis tshiab yeej muaj qhov zoo thiab qhov tsis zoo, cov txiaj ntsig ntawm kev txhim kho lub xov tooj ntse ntse yog qhov tseeb heev. Txawm hais tias ntse meters ib leeg xwb tsis tuaj yeem txo koj cov nqi hluav taws xob, nkag mus rau cov ntaub ntawv ntau dua tiag tiag - cov ntaub ntawv tuaj yeem pab koj tswj koj txoj kev siv ntau dua. Ntse meters tuaj yeem ua cov hauv qab no: Los ntawm kev sau cia thiab kev saib xyuas cov ntaub ntawv ntiag tug no, qee tus neeg tuaj yeem nkag mus rau cov qauv ntawm tus kheej no lossis cov ntaub ntawv sib koom ua ke nrog cov neeg sab nraud. Txawm hais tias nws yog qhov tsis tshua muaj tshwm sim vim muaj kev tiv thaiv kev tiv thaiv, tsis pub twg paub thiab kev ua txhaum kev nyab xeeb tsis yooj yim sua.
Ntxiv mus, ntse meters yog tsim thiab ntsia raws IEC / EN cov qauv (ntsuas tus qauv). Tag nrho cov ntse meters yuav tsum ua kom tiav lub chaw haujlwm hluav taws xob siv hluav taws xob teeb tsa tau los ntawm Lub Tsev Haujlwm Hauv Tebchaws. Cov khoom siv no lawv tus kheej siv xov tooj cua ntau (RF) / Fais fab kab cab kuj (PLC) / GPRS cov cim los xa cov ntaub ntawv ntsig txog kev siv fais fab dhau ntawm wireless network.
Qee qhov kev ntsuam xyuas tau pom tias lub hwj chim tswj hwm (xws li Dimmers) yuav tiv thaiv cov chaw kaw neeg ncaj qha los ntawm kev sau cia raug. Txawm li cas los xij, feem ntau, ntse metres zoo li yog qhov tseeb yog metres meters vim tias lawv tsis cuam tshuam los ntawm tib neeg kev ua yuam kev lossis teeb meem kev siv tau. Ua ntej qhia txog cov kev qhia ntawm cov ntse meters, muaj qhov tsis raug lossis "cov ntawv them nyiaj" yog qhov muaj teeb meem nyeem ntawv yuav muaj teeb meem siv cov cwj pwm.
Tam sim no thoob ntiaj teb, cov xeev sib txawv thiab hluav taws xob muaj cov cai sib txawv rau kev txhim kho cov chaw ntse meters. Qee cov tuam txhab tau hloov cov qauv tsoos nrog cov qauv tshiab "ntse", tab sis lwm tus tsuas yog tsom rau cov qauv hloov kho tshiab thaum tsim nyog.
Nws raug nquahu kom koj tham nrog tsoomfwv xeev lossis lub zog tsum tau txais qhov tseeb tshaj plaws thiab nce - mus rau hauv cov ntaub ntawv hauv nroog.
Koj cov khoom siv fais fab yuav muab cov khoom siv uas xav tau lub ntsuas kub. Yog tias koj lub ntsuas kev ntsuas tam sim no tsis ua tiav lossis xaus rau nws lub neej muaj txiaj ntsig thiab kev xav tau hloov, koj yuav tau txais lub ntsuas kub.
Feem ntau, cov ntse meters tuaj yeem txuag tau nyiaj rau tsev neeg uas npaj siab saib xyuas lawv cov kev siv thiab kho lawv cov kev siv tau kev siv sijhawm. Lawv yog cov kev sib cav sib ceg ntau dua li cov pa taws me me, thiab koj tsis tas yuav txhawj txog "kwv yees" nyeem. Peb txoj haujlwm yog, yog, cov txiaj ntsig ntawm cov txiaj ntsig ntse meters tawm ntawm cov kev pheej hmoo me me uas cuam tshuam nrog kev ceev ntiag tug thiab kev nyab xeeb. Nco ntsoov, ntse meters tsuas yog txuag lub zog yog tias koj muaj lub zog paub, yog li thov saib xyuas koj li kev noj thiab hloov mus rau lub zog txuag!
