Txawm hais tias LED zaub nyem teeb liab tsis yog qhov teeb meem loj, nws yog mob taub hau. Nws tsis tsuas yog cuam tshuam qhov zoo ntawm daim duab playback, tab sis kuj cuam tshuam rau tus neeg siv kev xav. Dab tsi yog qhov ua rau LED teeb pom teeb meem? Puas muaj cov tshuaj zoo?
LED teeb ntsais muag vim li cas
1. Lub thawv tsav tsheb tsis yog.
2. Lub network cable ntawm lub khoos phis tawm thiab lub vijtsam ntev dhau lossis lub network cable raug yuam kev.
3. Daim npav xa ntawv tau tawg.
4. Daim npav tswj hwm tau tawg. Txheeb xyuas tias lub teeb me me rau daim npav tswj tau zes lossis tsis. Yog hais tias nws tsis zes, nws yuav tawg.
5. Puas yog txoj kab nruab nrab ntawm lub zog siv hluav taws xob thiab daim npav tswj kav tau luv?
6. Cov zis hluav taws xob ntawm lub zog hluav taws xob tsis ruaj khov, thiab lub hwj huam nrog cov tswj daim npav tsis muaj ntau lub rooj zaum sib luag.
LED zaub teeb nyem coj los daws teeb meem
1. Yog tias tag nrho lub vijtsam plooj, daim duab yog sib ntswg, feem ntau tus tsav tsheb loader tsis yog lawm, rov kuaj tus tsav tsheb loader, nws tsis tuaj yeem rub tawm thiab rov ua dua.
2. Lwm txoj kev tuaj yeem yog xa daim npav tawg. Lub sijhawm no, daim npav xa khoom xav xav hloov.
3. Yog tias nws coj tsis tau lub teeb nrawm, nws feem ntau yog lub teeb meem ua kom muaj zog. Hloov cov kab ke, lossis kho cov teeb tsa lub teeb, tuaj yeem daws tau! Yog tias nws yog lub xeev flashing ntawm lub hnub qub, yuav muaj teeb meem nrog daim npav tsav tsheb, lossis nws yuav muaj teeb meem nrog kev daws teeb meem ntawm daim npav xa mus. Lwm qhov tuaj yeem yog qhov teeb meem kev xa hluav taws xob (tsis txaus siv hluav taws xob, xov xwm tsis xwm yeem, hluav taws xob cuam tshuam). Thaum tsim cov PCB, xav txog txoj kab xov hlau ntawm lub zog hluav taws xob thiab cov paib kab, thiab cov txheej txheem PCB tsim ntau ntxiv. Kuj tseem muaj qee qhov kev txhim kho hauv kev ntxiv ntau lub zog ntxiv rau qhov module.
4. Yog hais tias cov ntawv xa tuaj nrog lub ntsais muag (muaj qhov teeb meem tsis dawb ntawm ib ncig ntawm cov ntawv nyeem, lub teeb nyem tsis meej, thiab ploj tom qab cov ntawv ploj), qhov no yog qhov teeb meem nrog daim npav teeb duab. Hauv cov yam ntxwv ntawm cov zaub, tso tseg "Qhia zais hauv qab cov ntawv qhia zaub mov", "Hloov txoj kev hloov ncaj" "Cov teebmeem" tuaj yeem daws cov teeb meem no.
