Nrog rau kev nce qib ntxiv ntawm cov neeg caij tsheb thiab cov tsheb lag luam, cov khoom siv hluav taws xob tsheb tau siv dav hauv cov tsheb. Txhawm rau kom ntseeg tau tias ib txwm ua ntawm cov khoom siv hluav taws xob hauv kev ua haujlwm hauv lub sijhawm ua haujlwm, nws yog qhov sib txawv, thiab hluav taws xob, cuam tshuam rau cov khoom lag luam ntawm cov khoom lag luam. Yog li ntawd, International Standard ISO 7637 tau tso cov kev txhaj tshuaj tiv thaiv hluav taws xob rau hauv lub zog hluav taws xob ntawm lub zog hluav taws xob ntawm lub zog hluav taws xob.
ISO 7637 Txuj Ci, tseem hu ua: Cov tsheb hluav taws xob-hluav taws xob muaj kev sib cuam tshuam nrog kev siv hluav taws xob rau 12v thiab 24v fais fab mov system. Nws suav nrog ob qho tib si hluav taws xob rau hluav taws xob thiab emission Qhov ntawm electromagnetic kev ntsuas. Tag nrho cov qauv no Qhia txhua qhov kev ntsuas cov khoom siv rau cov cuab yeej siv thiab cov khoom siv uas tuaj yeem siv rau kev tsim cov hluav taws xob sib xyaw thiab ua kev xeem. Raws li niaj hnub no, ISO 7637 tus qauv tau raug tso tawm hauv plaub ntu. Raws li niaj hnub no, ISO 7637 tus qauv tau tso tawm hauv plaub qhov chaw los qhia cov qauv kev sim thiab muaj feem cuam tshuam rau kev nkag siab. Tom qab ntawd peb yuav tseem ceeb qhia rau ntu ob ntawm tus qauv no, ISO 7637-II, uas tau ua haujlwm los sim qhov sib xws ntawm peb cov ntsiav tshuaj rugged.
ISO 7637-II hu hluav taws xob kev ua kom haum raws cov kab tsuas yog. Nws qhia meej lub rooj ntev zaum rau kev sim cov khoom siv hluav taws xob uas tau tsim nrog cov neeg caij hluav taws xob thiab cov ntsuas hluav taws xob nrog rau kev txhaj tshuaj thiab ntsuas cov kev ntsuas ntawm cov khoom siv. Ua tsis tiav hom kev faib tawm kev faib tawm kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv tau los kuj tau muab. Nws yog qhov siv rau cov hom tsheb hauv txoj kev tsheb, txoj kev ywj pheej ntawm cov txheej txheem thev naus laus zis (piv txwv li Sparark Ignition lossis Diesel cav, lossis tsav hluav taws xob).
ISO 7637-II xeem suav nrog ntau qhov sib txawv ntawm kev sib txawv. Cov nce thiab poob sawv ntawm cov pulses lossis cov volulsicts yog nrawm, feem ntau nyob rau hauv nanosecond ntau yam. Kev sim siv hluav taws xob no yog tsim los sim sim txhua qhov xwm txheej hluav taws xob uas tsheb yuav ntsib hauv qab ntuj ntiaj teb, suav nrog cov khoom siv hluav taws xob tiag tiag. Ua kom ntseeg tau cov khoom siv nyob ruaj khov ntawm cov cuab yeej thiab cov neeg caij tsheb.
Kev sib xyaw ua ke ISO 7637-II-II ua raws li cov ntsiav tshuaj uas xeb rau hauv lub tsheb muaj ntau cov txiaj ntsig. Foremost, lawv cov kev ua haujlwm ruaj khov ua haujlwm thiab ua tau zoo, txo cov nqi txij nkawm thiab nce tag nrho cov khoom lag luam. Thib ob, ISO 7637-II-II ua raws li kev pom tseeb thiab tswj cov ntaub ntawv tseem ceeb, txhim kho tsheb kuaj mob thiab ua tau zoo. Thaum kawg, cov ntsiav tshuaj tuaj yeem sib txuas nrog lwm cov tshuab tsheb thiab cov khoom siv sab nraud, txhim kho kev sib txuas lus thiab kev sib txuas lus. Los ntawm adhering rau tus qauv no, peb tuaj yeem tsim kev ntseeg, kev ntseeg siab, thiab xa cov khoom lag luam zoo siab uas tau raws li cov neeg siv khoom zoo siab.
Ua raws li ISO 7637-II txheem hloov voltage tiv thaiv, cov ntaub pua chaw pua ntawm 34v muaj peev xwm tiv taus txog li 174V 300 cov tsheb thauj khoom muaj peev xwm tiv taus mus rau 174V 300 cov tsheb thauj khoom muaj peev xwm tiv taus rau 174V 3004V tsheb voltage fais fab mov. Nws xyaum txhim kho lub zog ntawm kev ua haujlwm tseem ceeb hauv cov tsheb xws li telemat, kev tshawb nrhiav hauv qab cov xwm txheej hnyav thiab kev poob haujlwm los ntawm kev ua tsis zoo.
