Lub zog ntawm lub qhov rooj of the elevator cia siab rau lub tshuab traction tsav cov hlua hlau kom nce thiab txo lub tsheb of elevator thiab nws qhov hnyav. Lub tshuab ua haujlwm of the elevator yog qhov tseem ceeb ntawm kev ua haujlwm of the elevator; nws feem ntau suav nrog cov ntsiab lus tseem ceeb xws li lub qhov rooj tsav tsheb, lub qhov rooj xauv lub cuab yeej, thiab lub qhov rooj tswj qhov system, txhua yam ua haujlwm hauv kev hais kwv txhiaj kom ntseeg tau tias tsis siv neeg qhib, kaw, thiab ua haujlwm zoo ntawm lub qhov rooj.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm of the elevator door locking mechanisms poob rau hauv peb pawg loj: mechanical, electromagnetic, thiab electronic. Mechanical locking mechanisms yog hom ntau tshaj plaws; lawv vam khom feem ntau ntawm cov cuab yeej siv tshuab-xws li xauv hooks, pins, thiab springs- kom ruaj ntseg thiab tso lub qhov rooj. Electromagnetic locking mechanisms siv electromagnetic quab yuam los xauv thiab qhib lub qhov rooj, feem ntau muaj xws li electromagnet, lub xauv ntsia liaj qhov rooj, thiab tswj Circuit Court. Electronic locking mechanisms sawv cev rau cov qauv niaj hnub hauv of the elevator door technology; Cov tshuab no siv cov thev naus laus zis tswj hluav taws xob-tshwj xeeb hauv cov tshuab xauv hluav taws xob thiab cov khoom siv hluav taws xob hauv lub qhov rooj- los tswj cov kev ntsuas xauv thiab xauv lub luag haujlwm.
Niaj hnub nimno of the elevator door control systems siv software algorithms los txheeb xyuas qhov tseeb -lub sij hawm hloov pauv ntawm qhov tsis kam ntsib thaum lub qhov rooj qhib thiab kaw. Los ntawm kev them nyiaj rov qab rau cov kev hloov pauv no hauv kev tsav tsheb, lub kaw lus txhim kho nws cov lus teb rau cov lus txib ceev thiab txhim kho nws txoj kev hloov mus rau qhov chaw tshwj xeeb. Txhawm rau kom muaj kev nyab xeeb, lub qhov rooj of the elevator feem ntau tau nruab nrog ntau yam kev tiv thaiv- xws li cov ntaub thaiv lub teeb, cov npoo kev nyab xeeb, thiab cov qauv mos-ntug- txhawm rau tiv thaiv cov xwm txheej cuam tshuam nrog cov neeg raug kaw los yog tsoo ntawm lub qhov rooj.
Lub qhov rooj of the elevator feem ntau siv ib qho ntawm ob qhov kev teeb tsa qhib: sab- qhov rooj zawv zawg lossis qhov chaw- qhib qhov rooj. Nyob rau sab - zawv zawg configuration, lub qhov rooj vaj huam sib luag swb tom qab ntawm ib sab ntawm lub elevator ncej thaum qhib. Hauv qhov chaw- qhib kev teeb tsa, lub qhov rooj vaj huam sib luag xaub tawm sab nraud ntawm qhov sib txawv, sib cais ntawm qhov chaw.
Nyob rau hauv kev muaj tiag, lub cev qauv ntawm of elevator tsaws qhov rooj yog qhov tsis yooj yim, feem ntau muaj tsuas yog ib txheej ntawm cov ntawv hlau. Tsis tas li ntawd, cov qhov rooj no muaj "sensor qhov muag tsis pom kev"- thaj chaw tshwj xeeb uas cov ntsuas kev nyab xeeb yuav tsis pom qhov cuam tshuam -tshwj xeeb, thaj tsam 10-centimeter nyob rau sab saum toj thiab hauv qab ntawm lub qhov rooj, nrog rau thaj tsam 2-centimeter nyob rau hauv qhov chaw. Kev tiv thaiv lub qhov rooj ntawm lub elevator lossis sim thaiv lawv nrog cov khoom me me yog qhov txaus ntshai heev, vim tias qhov kev ua no yuav ua rau lub qhov rooj qhib tsis tau xav txog, uas ua rau ntog lossis tsoo raug mob.
