Kev siv cov koob yees duab soj ntsuam hauv elevator. Thaum lub elevator feem ntau tsis siv, lub teeb fluorescent hauv lub tsheb yog nyob rau hauv lub zog txuag hluav taws xob. Yog tias koj xav tau saib xyuas lub thawv rau 24 teev, koj tuaj yeem xaiv lub koob yees duab infrared dome, txwv tsis pub koj tuaj yeem xaiv lub koob yees duab dome ib txwm. (Thaum ib tug neeg nkag mus rau hauv lub tsheb of elevator, lub teeb yuav cia li qhib). Vim lub tsheb of elevator yog luv heev, nws yog inevitable los rhuav tshem cov khoom ntawm lub siab nyiam. Lub sijhawm no, tus neeg siv tuaj yeem xaiv lub koob yees duab tawg-pov thawj hemisphere.
of the elevator yog ib lub chaw nqa khoom nrog ib puag ncig nyuaj. Lub cev muaj zog thiab lub zog hluav taws xob sab nraum lub tsheb yuav ua rau muaj kev cuam tshuam loj heev thaum nws khiav; kev cuam tshuam ntawm kev soj ntsuam video teeb liab yog ib qho teeb meem uas nquag ntsib los ntawm feem ntau ntawm cov tuam txhab engineering. Yog li yuav ua li cas zam nws?
Ua ntej tshaj plaws, los ntawm kev xaiv cov khoom siv, engineers thiab cov neeg siv yuav tsum sim lawv qhov zoo tshaj plaws los siv cov cuab yeej paub tab ntawm kev ua lag luam thiab tshwj xeeb hemispheric soj ntsuam lub koob yees duab nrog muaj zog tiv thaiv kev cuam tshuam rau elevator. Nyob rau tib lub sijhawm, siv elevator-dedicated cables thaum txuas, thiab ceev faj kom tsis txhob ua kom cov cables puas. Nyob rau hauv cov nqe lus ntawm lub hwj chim noj ntawm lub koob yees duab, siv lub hwj chim saib xyuas interface reserved los ntawm lub elevator kom ntau li ntau tau los mus tiv thaiv kev huam yuaj to; tab sis qhov teeb meem cuam tshuam tsis tuaj yeem daws tau hauv hom ib txwm muaj, thiab kev tiv thaiv kev cuam tshuam tuaj yeem raug txiav txim siab hauv kab sib kis.
Tam sim no, feem ntau of the elevator monitoring camera systems are built in a wired transmission mode using analog signals. Qhov kev sib txuas yog tso tawm rau ntawm lub platform zaub ntawm chav saib xyuas. Raws li rau qhov chaw tso saib, tsis muaj qhov tshwj xeeb yuav tsum tau ua. Nws yog tso tawm kom pom nyob rau hauv ib tug conspicuous thiab yooj yim-rau-saib raws li cov kev xav tau ntawm cov neeg siv. Qhov chaw nyob zoo.
Vim lub elevator me me thiab cov neeg ua haujlwm muaj neeg coob coob, thaum muaj xwm txheej tshwm sim, nws nyuaj rau kev cawm, tom qab ntawd thaum txhim kho lub koob yees duab saib xyuas, koj yuav tsum tau them sai sai rau cov txheej txheem kev khiav hauj lwm nruj thiab kev teeb tsa tshwj xeeb; tsis txhob txuas lossis rub cov cables tsis sib xws, thiab cov kab sib txuas yuav tsum ua raws li cov lus qhia tshwj xeeb. Tsis txhob sib tshooj random; qhov zoo ntawm cov khoom siv yuav tsum muaj kev ntseeg siab raws li qhov ua tau (xws li: koob yees duab, transformers, cables, thiab lwm yam), thiab cov ntaub ntawv ntsuam xyuas thiab daim ntawv pov thawj yuav tsum muaj. Ua li no, qhov tshwm sim ntawm ntau yam xwm txheej tuaj yeem raug txo.
Tsis tas li ntawd, qhov ntev ntawm cov kab yeeb yaj kiab, qhov muaj peev xwm ntau dua uas cov teeb liab sib tsoo yuav cuam tshuam rau cov yeeb yaj kiab, thiab qhov zoo ntawm cov teeb liab kis tau tus mob yuav txo; nyob rau hauv qee qhov chaw muaj kev lag luam loj, qhov twg yuav tsum tau saib xyuas hauv nruab nrab, qhov kev sib kis ntawm cov teeb liab analog Lub kaw lus yuav poob nws txoj haujlwm. Lub sijhawm no, cov tuam txhab engineering thiab cov neeg siv tuaj yeem siv hom kev xa xov hluav taws xob digital los txo cov teeb liab cuam tshuam thiab ua kom yooj yim rau kev xaim, lossis siv wireless kis tau tus mob kom tsis txhob muaj qhov cuam tshuam ntawm kev tsim hluav taws xob.
