Kev saib xyuas cov roj teeb nyob deb yog qhov tseem ceeb rau koj cov haujlwm. Yog tias tsis muaj kev tshuaj xyuas kom ntseeg tau, koj tsis tuaj yeem paub tam sim ntawd thaum lub roj teeb tsis raug thiab teeb meem tshwm sim tshwj tsis yog tias koj muaj cov neeg ua haujlwm ntawm lub chaw 24/7. Txawm li cas los xij, koj pheej pheej hmoo saib xyuas cov teeb meem khoom siv lossis cov xwm txheej hloov pauv uas tsis tuaj yeem kuaj pom yam tsis muaj qhov tsim nyog sensors thiab roj teeb saib xyuas qhov system ntsia.
Txawm hais tias cov txiaj ntsig ntawm kev siv lub tshuab hluav taws xob cov chaw taws teeb saib xyuas kom meej, qhov kev txiav txim siab siv wireless lossis wired sensors nrog lub kaw lus tsis pom tseeb. Wired thiab wireless sensors ob leeg muaj lawv qhov zoo thiab qhov tsis zoo. Paub txog cov kev xav tau tshwj xeeb ntawm koj daim ntawv thov yuav pab koj txiav txim siab seb qhov kev xaiv twg yog rau koj qhov project. Nov yog ob peb yam uas yuav tsum xav txog:
Tau txais daim duab tag nrho ntawm ob lub roj teeb saib xyuas
Lub chaw taws teeb saib xyuas roj teeb (BMS) yog qhov tseem ceeb rau roj teeb saib xyuas hauv kev ua haujlwm. A ntse BMS yuav ntes cov roj teeb hom, qhov hluav taws xob, qhov kub thiab txias, lub peev xwm, lub xeev ntawm tus nqi, kev siv hluav taws xob, kev them nqi, thiab lwm yam ntxwv. Nws tuaj yeem ua kom pom kev siv lub roj teeb thiab txo qhov kev pheej hmoo ntawm lub zog tsis ua haujlwm.
Txawm li cas los xij, koj tsuas tuaj yeem ua qhov feem ntau ntawm cov roj teeb saib xyuas lub tshuab los ntawm kev xaiv qhov zoo tshaj plaws ntawm cov xaim & wireless. Yog li ntawd, cia peb delve rau hauv kev sib tham:

• Cov txiaj ntsig ntawm wired BMS
a. Ceev
Feem ntau, wireless networks qeeb dua li cov xov tooj. Cov teeb liab wireless tuaj yeem cuam tshuam tau yooj yim los ntawm ib puag ncig ib puag ncig, xws li cov phab ntsa, cov plag tsev, thiab cov txee hauv qhov chaw, nrog rau kev cuam tshuam los ntawm lwm yam khoom siv hluav taws xob. Kev xa cov ntaub ntawv wireless kuj tseem nyob deb: qhov deb ntawm cov sensors nyob, qhov ua haujlwm tsis muaj zog.
b. Kev ntseeg tau
Ib txwm siv cov roj teeb saib xyuas cov kab ke tau hloov kho thiab txhim kho tau ntau xyoo lawm. Cov kev nce qib tseem ceeb tau ua kom ntseeg tau tias lawv muaj kev ntseeg siab heev. Lawv siv kev sib txuas ntawm lub cev ncaj qha thiab ntsib kev cuam tshuam tsawg dua piv nrog cov wireless.
c. Roj teeb tshuav
Wired sensors tuaj yeem ua kom lub zog siv tau ruaj khov, zam kev hloov pauv los ntawm cov teeb liab sib txawv wireless. Yog li, lawv pab kom sib npaug ntawm cov roj teeb thiab txuas ntxiv cov hlua roj teeb lub neej.
d. Nqi-zoo
Piv nrog wired sensors, wireless sensors xav tau wireless transmitter hardware ntxiv rau txhua lub sensor, uas yuav ua rau cov nqi wireless ntau dua li cov kev daws teeb meem.
e. Kev tu
Tus nqi zog ntawm kev tswj xyuas wired sensors feem ntau tsawg dua li cov wireless sensors txij li yav dhau los yuav tsum tau saib xyuas me ntsis. Wired sensors muaj peev xwm saib xyuas tas li ntau xyoo, txo cov nqi ntawm kev txheeb xyuas thiab hloov cov khoom siv tas sij hawm lossis tsis raug thiab cov nqi ntawm kev txheeb xyuas cov teeb meem kev sib txuas.
• Qhov tsis zoo ntawm kev saib xyuas kev siv xov tooj
a. Tsis muaj kev txav chaw
Vim hais tias cov kev soj ntsuam ntawm cov xov tooj cua nyob ntawm lub cev ntawm cov cables, muaj qhov tsis muaj qhov hloov pauv thaum yuav tsum tau hloov pauv. Kev xa rov qab cov cables feem ntau yog siv sijhawm ntev, nyob ntawm seb muaj pes tsawg cov cables yuav tsum tau rov qab thiab cov teeb meem ntawm cov ntsiab lus nkag.
b. Cov nqi installation
Tus nqi pib ntawm kev txhim kho ib qho kev saib xyuas kab ke tuaj yeem siab. Cables yuav tsum tau khiav ntawm phab ntsa, hauv qab hauv pem teb, thiab qee zaum faus. Cov nqi ua haujlwm cuam tshuam nrog cov haujlwm no tuaj yeem txwv tsis pub, thiab yog tias muaj teeb meem tom qab pom, kev nkag mus rau cov cables yog qhov nyuaj heev.
c. Cable puas
Muaj cov xwm txheej uas cov cabling txuas nrog cov sensors tuaj yeem raug puas ntsoog, loosened, los yog disconnected, los yog vim tib neeg yuam kev los yog, feem ntau, vim lwm yam hauj lwm ua nyob ib ncig ntawm nws. Hauv cov xwm txheej tsis tshua muaj, kev puas tsuaj rau cov cabling tuaj yeem ua rau tsis muaj kev cuam tshuam rau cov sensors. Yog li ntawd, cov cabling tej zaum yuav tsum tau yooj yim reconnected los yog, qhov phem tshaj, hloov. Hmoov zoo, Ethernet thiab RJ11 cabling yog pheej yig, tshwj xeeb tshaj yog thaum tsuas yog ib txoj kab lossis ob yog hloov.
• Cov txiaj ntsig ntawm wireless saib xyuas sensors
a. Yooj yim
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev saib xyuas wireless yog lub peev xwm los tso cov sensors txhua qhov chaw uas xav tau yam tsis muaj kev sib txuas ntawm cov phab ntsa, pem teb, thiab qab nthab, uas yuav pab txo qis lub sijhawm teeb tsa, tab sis nws xav tau sijhawm ntxiv rau software chaw nyob teeb tsa.
b. Mobility
Feem ntau cov wireless sensor manufacturers tso cai rau ntau lub wireless sensors txuas mus rau ib leeg. Ntxiv mus, cov nodes tshiab lossis sensors tuaj yeem muab ntxiv rau hauv lub network uas twb muaj lawm yam tsis tau khiav txuas ntxiv kom haum rau kev nthuav dav network.
UPS yuav lees paub tus qauv tsim nyob rau theem pib. Feem ntau yuav tsum tsis muaj cov sensors ntxiv rau lub network uas twb muaj lawm.
• Qhov tsis zoo ntawm kev saib xyuas wireless
a. Txo roj teeb lub neej
Wireless signals tuaj yeem cuam tshuam los ntawm kev cuam tshuam sab nraud. Txawm hais tias lub teeb liab yog qhov zoo lossis qhov tsis zoo yuav cuam tshuam ncaj qha rau lub zog noj ntawm txhua lub sensor thiab ua rau lub roj teeb tsis txaus ntseeg.
Wireless sensors kuj tseem muaj kev cuam tshuam deb. Raws li qhov tshwm sim, cov sensors nyob deb yuav feem ntau ua rau lub roj teeb lub neej tsis zoo.
b. Kev qeeb qeeb piv rau kev saib xyuas cov kab
Thaum txheeb xyuas cov xwm txheej ntawm lub sijhawm tiag tiag ntawm cov cuab yeej siv lossis cov chaw tseem ceeb, nws yog qhov tseem ceeb uas cov ntaub ntawv raug xa mus thiab muaj sai li sai tau. Raws li tau hais los saum toj no, wireless sensors muaj qhov cuam tshuam rau qhov nce latency, teeb liab cuam tshuam, thiab kev sib txuas poob uas yuav cuam tshuam qhov nrawm thiab sib xws ntawm cov ntaub ntawv ntws, txawm tias tsis muaj lub tswb tseem ceeb thiab ua rau muaj xwm txheej.
c. Complex rau configure
Configuring wireless sensor tes hauj lwm tuaj yeem yog qhov kev sib tw tsis tu ncua vim tias cov hloov pauv tshiab tau ntxiv rau lub network sensor. Re-positioning lub sensors thiab redeploying los yog reconstructing lub network yog yuav tsum tau kom ceev ceev ntawm cov ntaub ntawv kis tau tus mob.
d. Tsawg teeb liab ntau vim muaj kev cuam tshuam
Wireless cov ntaub ntawv tshaj tawm tau yooj yim tshaj xov tooj cua zaus (RF), uas ib txwm yuav tsum tau cuam tshuam nrog ntau yam cuam tshuam txog kev cuam tshuam uas tuaj yeem txo cov teeb liab lub zog thiab txo qis kev sib kis ceev. Cov teeb meem xws li phab ntsa thiab qhov rooj lossis lwm yam khoom siv uas ua haujlwm ntawm tib zaus yuav tsim kev tsis sib haum xeeb nrog cov ntaub ntawv xa mus.
Qhov kev ncua deb ntawm cov sensors thiab lawv cov hub saib xyuas kuj yog ib qho kev txwv. Qhov sib txawv loj txaus lossis cov qauv tsim ntawm ob lub ntsiab lus no tuaj yeem ua rau muaj kev puas tsuaj ntawm cov ntaub ntawv. Rau cov laj thawj no, ntau tus neeg ua haujlwm feem ntau raug yuam kom tsis txhob siv cov sensors rau lawv lub peev xwm los ntawm kev txo cov sijhawm pov npav ntawm cov ntaub ntawv.
e. Kev tu:
Nyob rau hauv cov nqe lus ntawm kev saib xyuas, txij li thaum lub wireless roj teeb saib xyuas qhov system muaj ntau dua qhov yuav ua tau yuam kev, kev saib xyuas ntau dua tuaj yeem xav tau.
Xaus
Lub hom phiaj ntawm lub ntse BMS yog txhawm rau txheeb xyuas cov roj teeb tsis raug thiab cov neeg siv lub tswb ua ntej kom tsis txhob muaj xwm txheej. Yog tias lub roj teeb ua tsis tiav tsis tuaj yeem ceeb toom rau lub sijhawm, lub kaw lus tsis muaj nuj nqis los saib xyuas. Yog li, xav txog tag nrho cov txiaj ntsig thiab qhov tsis zoo, kev daws teeb meem BMS yog qhov kev xaiv zoo dua.
