Ntaus teeb meem kev nyab xeeb yog qhov chaw nyab xeeb yog nyob ntawm infrared nqaj kuaj tau cov thev naus laus zis, feem ntau siv hauv kev lag luam cov xwm txheej automarios. Los ntawm kev sib txuas ntau lub teeb taws teeb hauv series (Cascaded), kev tiv thaiv kev nyab xeeb yog nthuav dav, ua rau kev ua haujlwm nthuav dav dav dav lossis cov khoom lag luam nthuav dav. Nws cov haujlwm tseem ceeb yog kom sai sai cov khoom siv kaw lossis lub tswb thaum tib neeg lossis cov khoom nkag mus rau thaj chaw txaus, tiv thaiv kev puas ntsoog.
I. Cov qauv theem pib thiab ua haujlwm ua haujlwm
Kev sib xyaw ua ke ntawm ib qho kev nyab xeeb lub teeb
Ib qho teeb meem kev nyab xeeb ib txwm muaj ob feem: lub transmitter thiab tus txais.
Lub transmitter tawm ntau yam parallel infrared kab teeb, sib sau ib "infrared lub teeb pov tseg";
Tus tau txais cov kab teeb thiab saib xyuas lub sijhawm tiag tiag seb lawv puas thaiv. Kev siv
Ib daim cascaded kev sib txuas lub teeb pov tseg txuas ntau lub teeb cig (xws li RS485 lossis mob siab ua haujlwm), ua kom lawv ua haujlwm ua ke.
Ntau cov transmitters thiab cov neeg tau txais kev sib txawv ntawm cov sib txawv (xws li ib puag ncig loj ntawm cov kab loj), sib sau ua ke kab hlau rhuav.
Txhua koog sib koom ua ke ib qho teeb liab. Thaum twg ib yam ntsuas pom ib qho kev thaiv kev, tag nrho cov kab ke tam sim ntawd ua rau muaj kev nyab xeeb rau kev nyab xeeb (xws li kaw lossis ceeb toom).
Kev Ua Haujlwm Logic
Thaum tsis muaj kev cuam tshuam, tus tau txais txhua qhov teeb liab ib txwm. Yog tias ib qho khoom (xws li tib neeg lub cev lossis cov cuab yeej) thaiv ib lossis ntau qhov kev hais kom tsis txhob muaj teeb meem thiab xa cov teeb meem nres tsheb, kom ua kom muaj kev phom sij rau cov khoom muaj teeb meem tam sim ntawd.
Ii. Cov Txheej Txheem Zoo Ntawm Cascaded Kev Nyab Xeeb Lub Teeb
Yoog tau yooj yim ntawm kev tiv thaiv ntau
Ib daim ntaub thaiv lub teeb muaj kev tiv thaiv muaj kev tiv thaiv lossis dav (piv txwv li (0.3-2 meters). Cascading tuaj yeem npog thaj tsam ntawm kaum tawm meters lossis loj dua li cov xovxwm loj dua tshiab), tshem tawm cov khoom siv khoom lag luam loj), tshem tawm cov khoom siv kev cai, cov khoom siv tau thiab txo nqi. Synchronized teb, tsis muaj kev nyab xeeb dig muag
Cascaded units sib txuas lus siv cov txheej txheem sib koom ua ke, kom muaj kev tiv thaiv, tag nrho cov chaw muaj kev tiv thaiv kev ruaj khov, kev tiv thaiv kev ruaj ntseg kev tsis txaus ntseeg.
Yooj Yim Installation thiab Txij Nkawm
Piv nrog rau ntau cov teeb meem ywj siab nrog cov xaim hluav taws xob sib cais thiab kev tswj hwm, ib qho system cascaded qhia lub zog thiab tswj cov xaim, txo cov ntaub hlau, txo cov ntaub qhwv. Thaum lub sijhawm saib xyuas, kev kuaj mob npav tuaj yeem nrhiav cov kev ua haujlwm tsis raug, txhim kho kev ua tau zoo.
