Kev Taw Qhia
Hauv cov xwm txheej xws li kev ua haujlwm ntawm lub tshuab nqa neeg caij tsheb, kev tsim khoom hauv kev lag luam, thiab kev tsav tsheb uas tseem ceeb rau kev nyab xeeb ntawm lub neej, txawm hais tiasme me hloovtej zaum yuav zoo li tsis tseem ceeb, nws ua lub luag haujlwm ntawm "kab tiv thaiv tsis pom". Txhawm rau kom ntseeg tau tias nws ua tau zoo tshaj plaws hauv cov txheej txheem kev nyab xeeb tseem ceeb, kev lag luam tau tsim cov qauv ntawv pov thawj nruj, kom ntseeg tau tias txhua lub qhov hloov pauv tuaj yeem tiv taus kev xeem kev nyab xeeb.
Lub voj voog kev nyab xeeb ntawm lub elevator yog "bolt" uas tiv thaiv kev txav mus rau saum thiab nqis.
Hauv lub voj voog kev nyab xeeb ntawm lub elevator,micro hloov yog ib qho tseem ceeb "bolt". Thaum lub qhov rooj of the elevator tsis kaw tag nrho lossis lub tsheb tshaj qhov txwv txoj haujlwm, qhov sib xwsmicro hloov yuav txiav lub voj voog tam sim ntawd thiab yuam kom lub elevator tsum tsis txhob khiav. Piv txwv li, hauv cov khoom siv xauv ntawm lub qhov rooj hauv pem teb thiab lub qhov rooj tsheb,micro hloov tuaj yeem ntes tau qhov rooj kaw tag. Yog tias muaj qhov sib txawv me ntsis, nws yuav ua rau muaj kev tiv thaiv kev nyab xeeb. Cov qhov hloov no yuav tsum dhau qhov kev sim hnyav kom ntseeg tau tias lawv tsis ua haujlwm tom qab ntau txhiab qhov rooj qhib thiab kaw, tsim kom muaj kev nyab xeeb rau txhua tus neeg caij tsheb hauv lub elevator.
Cov xauv qhov rooj kev nyab xeeb hauv kev lag luam yog "cov neeg zov rooj vag" tiv thaiv kev ua haujlwm tsis raug.
Hauv cov chaw tsim khoom, cov xauv qhov rooj kev nyab xeeb nrogmicro hloovcov khoom siv yog cov "neeg zov qhov rooj" tiv thaiv kev raug mob. Thaum cov khoom siv khiav, tsuav yog muaj ib tug neeg sim qhib lub qhov rooj tiv thaiv, qhovmicro hloov yuav txiav tawm lub hwj chim sai sai thiab ua rau cov khoom siv nres sai sai kom tiv thaiv tus neeg teb xov tooj kom tsis txhob raug mob los ntawm cov khoom tig ceev ceev. Tus nqi zog thiab qhov ceev teb ntawm cov hloov pauv no muaj cov kev cai nruj, thiab lawv yuav tsum teb hauv milliseconds kom ntxiv "kev pov hwm ob npaug" rau kev tsim khoom lag luam.
Cov txheej txheem kev nyab xeeb ntawm lub tsheb yog cov "transmitters" ntawm cov teeb liab nres.
Cov qhov hloov teeb nres, cov qhov hloov txuas lub hnab cua nyab xeeb, thiab lwm yam, yog qhov tseem ceeb.micro hloovkom muaj kev nyab xeeb thaum tsav tsheb. Thaum nres, lub teeb liab nres yuav xa ib lub teeb liab tam sim ntawd, ua rau lub teeb liab nres ci thiab ua rau lub kaw lus ABS ua haujlwm;micro hloov ntawm lub rooj zaum sensor yuav kho lub zog ntawm lub hnab cua kev nyab xeeb raws li tus neeg caij tsheb zaum. Qhov ruaj khov ntawm cov keyboards no cuam tshuam ncaj qha rau kev nyab xeeb ntawm lub tsheb. Yog tias lawv ua tsis tiav, nws yuav ua rau muaj xwm txheej xws li kev sib tsoo tom qab thiab kev tawg ntawm lub hnab cua tsis tau xav txog. Yog li ntawd, lawv cov kev ntseeg tau siab heev.
Daim ntawv pov thawj kev nyab xeeb yog "kev pov hwm ob npaug" rau kev ntseeg tau.
Txhawm rau kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm micro Cov qhov hloov pauv hauv cov txheej txheem kev nyab xeeb tseem ceeb, muaj cov qauv cai xws li ISO 13849 thiab IEC 61508. Cov qauv no zoo li "cov qauv xeem", teeb tsa cov cim qhia nruj txog lub neej ntawm qhov hloov pauv, kev tiv thaiv kev cuam tshuam, thiab kev hloov pauv mus rau qhov chaw ib puag ncig hnyav. Thaum lub sijhawm ua daim ntawv pov thawj, cov qhov hloov pauv yuav tsum dhau ntau qhov kev sim xws li kub siab, kev co, thiab plua plav, piv txwv li, hauv daim ntawv pov thawj ISO 13849, cov qhov hloov pauv yuav tsum dhau ntau lab qhov kev sim voj voog kom ua pov thawj tias lawv yuav tsis ua tsis tiav sai sai hauv kev siv mus sij hawm ntev. Tsuas yog cov khoom uas dhau daim ntawv pov thawj thiaj li siv tau hauv cov txheej txheem kev nyab xeeb tseem ceeb.
Xaus lus
Micro Cov qhov hloov pauv hauv cov txheej txheem kev nyab xeeb tseem ceeb siv cov kev ua haujlwm meej los tiv thaiv lub neej thiab kev nyab xeeb ntawm kev tsim khoom. Cov qauv ntawv pov thawj nruj ntxiv "kev pov hwm ob npaug" rau lawv qhov kev ntseeg tau, ua kom ntseeg tau tias txhua qhov kev ua kom raug thiab tsis muaj qhov yuam kev. Nrog kev txhim kho ntawm kev paub txog kev nyab xeeb, cov qhov hloov pauv me me no yuav txuas ntxiv sawv ntsug hauv thaj chaw sib ntaus sib tua tsis pom thiab dhau los ua cov tub rog tseem ceeb hauv lub kaw lus kev nyab xeeb.
