Kev tsis nkag siab 1: Cov kev tswj cov kev tswj hwm tau zoo dua.
Cov kev tsim tawm txawv teb yog ruaj khov thiab paub tab. Txawm li cas los xij, lawv kim kim, thiab vim muaj kev sib txawv hauv cheeb tsam, lub sijhawm ua haujlwm yuav tsis zoo, thiab tus nqi pabcuam yog qhov siab. Nyob rau tib lub sijhawm, vim qhov sib txawv hauv kev coj noj coj ua hauv kev coj noj coj ua hauv Suav teb, thiab ntau lub zog tsis haum rau Suav teb cov neeg siv hauv tebchaws thiab cov kev xav tau ntawm Suav cov neeg siv. Ntawm chav kawm, ntau cov khoom lag luam Suav teb muaj cov khoom lag luam me me, muaj peev xwm tsim muaj zog, thiab ob peb lub tshuab tsim nyog, yog li engineers yuav tsum tau xaiv zoo. Txhawm rau txhawb lawv cov khoom lag luam, ntau tus tswj hwm Suav tsim tau cov kev tsim qauv ntawm kev tsim khoom hauv Taiwan, Tebchaws Asmeskas thiab cov cheeb tsam thiab thaj chaw los ua kev muag khoom dag. Qhov tseeb, cov khoom lag luam zoo muaj teeb meem loj, thiab cov kws ua choj yuav tsum tau ceev faj txog qhov xwm txheej no.
Tsis to taub 2: tus dav dav lub cev ntawm daim npav nyeem ntawv, qhov zoo dua
Qee cov tswj hwm thov kom tau tshaj nrog daim npav nyeem ntawm ntau hom ntawv, xws li 485 hom ntawv, wiegand {} hom ntawv, tab sis qhov no yeej tsis tsim nyog. Txawm hais tias cov qauv no muaj qee qhov zoo hauv qee qhov, lawv tsis tau raws li cov qauv thoob ntiaj teb, uas yuav ua rau cov kev hloov kho yav tom ntej, nthuav dav thiab kev tiv thaiv kev cuam tshuam. Peb ua raws li lub hauv paus ntsiab lus uas siv tau, ruaj khov thiab qauv kev ua raws cai yog qhov zoo tshaj plaws. Nws raug nquahu tias koj tsuas xav tau daim npav nyeem ntawv uas ua tau raws li tus qauv thoob ntiaj teb ntawm Wiegand 26bit. 90% ntawm imported nkag tswj tau raws li tus qauv no.
Tsis to taub 3: cov muaj zog dua cov haujlwm, qhov zoo dua
Ntau cov kev tswj hwm hauv tsev txhawb nqa lawv cov khoom muaj zog npaum li cas, thiab ib qho kev ua haujlwm tshaj plaws ntawm kev tswj hwm. Qhov tseeb, kev ruaj khov, kev ua haujlwm thiab yooj yim kev ua haujlwm yooj yim yog qhov tseem ceeb tshaj plaws rau kev nkag mus. Peb xav tias muaj zog nthuav tawm cov haujlwm tau thaiv thiab muaj thaum cov neeg yuav tsum tau ua kom tau raws li lawv cov kev xav tau. Qee lub zog uas cov neeg muas zaub tsis siv yuav tsum tsis txhob pom zoo rau cov neeg siv khoom, uas tuaj yeem txo tus nqi cob qhia thiab kev saib xyuas, thiab cov neeg siv khoom txaus siab rau lawv siv.
Tsis to taub 4: tus nqi kim dua tus nqi, qhov zoo dua lossis pheej yig dua tus nqi, qhov zoo dua
Cov khoom lag luam uas muaj tus nqi zoo ua tau zoo yog cov khoom lag luam zoo tshaj plaws. Cov khoom kim dua yuav yog vim tias lawv cov khoom tsim tsis yog siab lossis tus nqi tshaj tawm yog qhov siab dhau, tsis tas ua yog vim tias cov khoom muaj nqis yog siab. Cov khoom lag luam pheej yig kuj tseem yog qhov txiaj ntsig ntawm cov chaw tsim khoom rau ib sab kev lag luam, txo peev hauv kev tiv thaiv kev tiv thaiv, lossis siv cov khoom ua haujlwm qis dua thiab ob txhais tes. Yog li ntawd, engineers yuav tsum ua kom lawv lub qhov muag qhib thiab ua kom muaj kev txheeb xyuas qhov tsim nyog ntawm cov khoom lag luam kev ua haujlwm-tus nqi.
