Yuav ua li cas txiav txim siab yog tias daim npav LED tswj tau nyob rau hauv ib txwm ua haujlwm?
Tom qab lubtswj daim npavyog powered on, thov saib lub hwj chim qhia lub teeb ua ntej.Lub teeb liab qhia tias 5V voltage tau txuas nrog.Yog tias nws tsis teeb, thov tua 5V fais fab mov tam sim ntawd.Xyuas seb qhov 5V ua haujlwm voltage puas txuas tau zoo, seb puas muaj overvoltage, rov qab kev sib txuas, tsis ua haujlwm, tso tawm luv luv Circuit Court, thiab lwm yam. Thov siv cov khoom siv hluav taws xob sib cais 5V los tswj daim npav.Yog tias lub teeb liab tsis nyob, nws yuav tsum tau kho.
Kev daws teeb meem dav dav rau LED tswj daim npav tsis raug
1. Paub meej tias daim npav tswj tau sib xws nrog software.
2. Xyuas seb qhov txuas txuas puas yog xoob lossis xoob, thiab paub meej tias cov kab txuas txuas tau siv los txuastswj daim npavyog sib xws nrog daim npav tswj.Qee daim npav tswj hwm siv ncaj qha (2-2, 3-3, 5-5), thaum lwm tus siv (2-3, 3-2, 5-5).
3. Xyuas kom meej tias cov khoom siv tswj lub cev muaj zog zoo.
4. Xaiv cov khoom tsim nyog qauv, raug hom kis tau tus mob, raug serial chaw nres nkoj naj npawb thiab yog baud npaum li cas raws li tus tswj daim card software thiab daim ntawv tswj koj xaiv, thiab kom raug teeb tsa qhov chaw nyob me ntsis thiab baud tus nqi ntawm cov tswj system hardware raws li cov Dip hloov daim duab qhia hauv software.
5. Yog tias tom qab kuaj xyuas thiab kho cov lus saum toj no, tseem muaj teeb meem ntawm kev thauj khoom, thov siv lub tshuab multimeter los ntsuas seb qhov chaw nres nkoj ntawm lub khoos phis tawj txuas nrog lossis cov cuab yeej tswj hwm puas raug puas tsuaj kom paub meej tias nws yuav tsum tau xa rov qab mus rau lub chaw tsim khoom siv computer lossis tswj qhov system hardware rau kev kuaj.
6. Yog tias qib thib tsib tsis yooj yim, thov hu rau cov chaw tsim khoom rau kev txhawb nqa.
Feem ntau Phenomena ntawm LED Control Card Malfunctions
Phenomenon 1: Tom qab txuas thiab siv rau, tsuas yog qee qhov kev pab cuam yuav tsum tsis ua si thiab pib ua si dua.
Qhov laj thawj tseem ceeb yog qhovfais fab movtsis txaus thiab daim npav tswj tau rov pib dua.1. Txo qhov ci ci;2. Cov khoom siv hluav taws xob nrog daim npav tswj tau los nrog ob chav tsev tsawg dua;3. Ua kom muaj zog ntxiv
Phenomenon 2: Thaum daim npav tswj tau zoo li qub, lub vijtsam zaub tsis pom lossis qhov ci ntsa iab yog qhov txawv txav.
Tom qab daim npav tswj tau txuas nrog cov duab tsav tsheb thiab lub zog rau, lub neej ntawd yog 16 scans.Yog tias tsis muaj cov zaub, thov xyuas seb cov ntaub ntawv polarity thiab OE polarity nqis hauv kev tswj software puas yog;Yog tias qhov ci ntsa iab yog qhov txawv txav thiab muaj ib txoj kab tshwj xeeb, nws qhia tau hais tias OE qhov chaw yog thim rov qab.Thov teev OE kom raug.
Phenomenon 3: Thaum xa cov ntaub ntawv mus rau daim npav tswj, lub kaw lus ceeb toom "Yuav tshwm sim, kev xa tsis tau"
Thov xyuas seb qhov kev sib txuas lus kev sib txuas lus puas yog, seb lub jumper ntawm daim npav tswj tau dhia ntawm qhov chaw sib txuas, thiab seb cov kev txwv hauv "Control Card Settings" puas yog.Tsis tas li, yog tias qhov ua haujlwm voltage tsawg dhau, thov siv lub ntsuas ntsuas ntsuas thiab xyuas kom meej tias qhov hluav taws xob siab tshaj 4.5V.
Phenomenon 4: Tom qab cov ntaub ntawv raug thauj khoom, lub vijtsam zaub tsis tuaj yeem tso tawm ib txwm
Xyuas seb qhov kev xaiv cov ntawv luam tawm hauv qhov "Control Card Settings" puas yog.
Phenomenon 5: Kev sib txuas lus tsis zoo thaum lub sij hawm 485 networking
Thov xyuas seb txoj kev sib txuas ntawm txoj kab sib txuas puas yog.Tsis txhob txuas cov kab kev sib txuas lus ntawm txhua qhov screen ua ke rau lub computer interface los ntawm kev yuam kev, vim qhov no yuav ua rau muaj kev cuam tshuam tsis zoo thiab ua rau muaj kev cuam tshuam loj rau cov teeb liab kis.Txoj kev sib txuas kom raug yuav tsum raug saws, raws li tau piav qhia hauv "Kev Sib Txuas Lus Sib Txuas Siv thiab Kev Ceeb Toom".
Yuav daws teeb meem kev sib txuas lus li cas thaum siv GSM cov ntaub ntawv xa mus thiab kev hu xov tooj rau cov chaw taws teeb?
Yuav daws teeb meem kev sib txuas lus li cas thaum siv GSM cov ntaub ntawv xa mus thiab kev hu xov tooj rau cov chaw taws teeb?Ua ntej, xyuas seb puas muaj teeb meem nrog MODEM.Tshem tawm MODEM txuas nrog daim npav tswj thiab txuas mus rau lwm lub computer.Txoj kev no, ob qho tib si xa thiab txais MODEMs txuas nrog lub khoos phis tawj thiab txiav tawm los ntawm kev tswj hwm.Rub tawm lub software hu ua "Serial Port Debugging Assistant" los ntawm internet, thiab siv nws los teeb tsa thiab kho MODEM tom qab kev teeb tsa.Ua ntej, teeb tsa MODEM ntawm qhov kawg tau txais rau cov lus teb tsis siv neeg.Txoj kev teeb tsa yog qhib tus pab cuam debugging ntawm ob qhov kawg, thiab nkag mus rau "ATS0 = 1 Enter" hauv tus pab cuam debugging ntawm qhov kawg tau txais.Cov lus txib no tuaj yeem teeb tsa MODEM ntawm qhov tau txais qhov kawg rau cov lus teb tsis siv neeg.Yog tias qhov teeb tsa ua tiav, AA qhov taw qhia teeb ntawm MODEM yuav teeb.Yog tias nws tsis taws, qhov teeb tsa tsis ua tiav.Thov xyuas seb qhov kev sib txuas ntawm MODEM thiab lub khoos phis tawj puas yog thiab yog tias MODEM tau qhib.
Tom qab qhov kev teeb tsa tsis siv neeg teb tau ua tiav, nkag mus rau "Tus Xov Tooj Tau Txais, Sau" hauv qhov chaw nres nkoj serial debugging pab ntawm qhov kawg xa, thiab hu rau qhov kawg tau txais.Lub sijhawm no, qee cov ntaub ntawv tuaj yeem kis tau los ntawm qhov kawg xa mus rau qhov kawg tau txais, lossis los ntawm qhov kawg tau txais mus rau qhov kawg xa.Yog tias cov ntaub ntawv tau txais ntawm ob qhov kawg yog qhov qub, kev sib txuas lus tau raug tsim, thiab lub teeb qhia CD ntawm MODEM yog qhib.Yog tias tag nrho cov txheej txheem saum toj no yog qhov qub, nws qhia tau tias kev sib txuas lus MODEM yog qhov qub thiab tsis muaj teeb meem.
Tom qab kuaj xyuas MODEM yam tsis muaj teeb meem, yog tias kev sib txuas lus tseem raug thaiv, qhov teeb meem yuav yog vim qhov kev tswj hwm daim npav.Txuas MODEM mus rau daim npav tswj, qhib daim npav tswj software ntawm qhov kawg xa, nyem Nyeem Rov Qab Chaw, xyuas seb qhov chaw nres nkoj baud npaum li cas, qhov chaw nres nkoj serial, raws tu qauv, thiab lwm yam teeb tsa raug, thiab tom qab ntawd nyem Sau Chaw tom qab ua. kev hloov.Qhib Offline King software, teeb tsa cov kev sib txuas lus sib txuas thiab cov kev txwv hauv hom kev sib txuas lus, thiab thaum kawg xa cov ntawv.
