Kev ua haujlwm kom muaj kev nyab xeeb ntawm cov tshuab hluav taws xob thiab lwm yam khoom siv hluav taws xob yog qhov tseem ceeb heev thaum ua haujlwm hauv qhov chaw uas muaj cov pa roj, cov pa dej lossis cov hmoov av tawg. Kev pheej hmoo ntawm kev tawg los ntawm kev ua tsis tiav ntawm cov khoom siv tuaj yeem muaj cov txiaj ntsig loj heev, yog li kev xaiv cov khoom siv hluav taws xob zoo yog qhov tseem ceeb heev.
Thaum xaiv cov khoom siv hluav taws xob rau kev siv hauv thaj chaw muaj kev phom sij rau kev tawg, qhov yuav tsum xav txog thawj zaug yog kev faib tawm ntawm thaj chaw. Cov chaw muaj kev phom sij raug muab faib ua thaj chaw lossis kev faib raws li qhov kub hnyiab ntawm huab cua ib puag ncig. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv xaiv rau ib cheeb tsam tshwj xeeb yog tsim nyog rau qhov chaw tshwj xeeb ntawd.
Qhov tom ntej no uas yuav tsum xav txog yog hom lub cev muaj zog uas xav tau rau ib daim ntawv thov tshwj xeeb. Muaj ob hom lub cev muaj zog: uas tsis tawg thiab uas tsis tawg. Lub cev muaj zog uas tsis tawg yog tsim tshwj xeeb los tiv thaiv kev kub hnyiab ntawm cov pa phem los ntawm cov hluav taws xob, thaum cov lub cev muaj zog uas tsis tawg tsis muaj kev tiv thaiv zoo li no. Hom lub cev muaj zog uas xav tau rau ib daim ntawv thov tshwj xeeb yuav tsum tau txiav txim siab kom ntseeg tau tias muaj kev nyab xeeb tshaj plaws.
Qhov theem uas cov khoom siv tiv thaiv ib puag ncig yog lwm qhov tseem ceeb. Cov khoom siv hluav taws xob hauv thaj chaw muaj kev phom sij rau kev tawg yuav tsum muaj qib kev tiv thaiv tsim nyog. Qhov no hu ua qib Ingress Protection (IP). Qib IP qhia txog qib kev tiv thaiv uas lub cuab yeej muab los ntawm cov hmoov av thiab dej. Nws yog ib qho tseem ceeb heev uas yuav tsum xaiv cov khoom siv nrog qib IP uas haum rau ib puag ncig, vim qhov no txo qhov kev pheej hmoo ntawm kev tawg.
Lwm yam tseem ceeb uas yuav tsum xav txog thaum xaiv cov khoom siv hluav taws xob rau kev siv hauv thaj chaw muaj kev phom sij rau kev tawg yog qhov kub thiab txias ib puag ncig. Qhov kub thiab txias hauv cov huab cua muaj kev phom sij rau kev tawg tuaj yeem dav, thiab cov khoom siv xaiv yuav tsum tau ntsuas kom ua haujlwm hauv qhov ntau ntawd. Cov khoom siv hluav taws xob yuav tsum tau xaiv nrog qhov kub thiab txias kom raug kom ntseeg tau tias ua haujlwm tau zoo. Cov ntaub ntawv siv los tsim cov khoom siv hluav taws xob kuj yog ib qho tseem ceeb uas yuav tsum xav txog. Txhua qhov ntawm cov cav hluav taws xob thiab lwm yam khoom siv siv hauv thaj chaw muaj kev phom sij rau kev tawg yuav tsum tau ua los ntawm cov ntaub ntawv uas muaj peev xwm tiv taus qhov chaw ib puag ncig tam sim no. Qhov no suav nrog kev siv cov ntaub ntawv uas tiv taus xeb thiab tsis tshua muaj kev tawg hauv qab kev nyuaj siab. Kev xaiv cov ntaub ntawv zoo pab ua kom ntseeg tau tias cov khoom siv siv tau ntev thiab kev nyab xeeb ib puag ncig.
Xaus lus, thaum xaiv cov khoom siv hluav taws xob rau kev siv hauv thaj chaw muaj kev phom sij rau kev tawg, kev faib tawm ntawm thaj chaw, hom lub cev muaj zog xav tau, qib kev tiv thaiv, qhov kub thiab txias, cov ntaub ntawv siv rau kev tsim kho thiab lawv cov khoom yuav tsum tau xav txog. zoo. kev teeb tsa. Kev xav txog cov yam no yuav pab ua kom cov khoom siv hluav taws xob ua haujlwm tau zoo thiab ntseeg tau hauv cov chaw muaj kev phom sij. Nco ntsoov tias kev nyab xeeb yeej ib txwm yog qhov tseem ceeb tshaj plaws thaum ua haujlwm hauv thaj chaw muaj kev phom sij rau kev tawg.
