1. Relay 89 Tsis Ua Haujlwm
Lub elevator kev nyab xeeb Circuit Court qhib, thiab cov xaim sab nraud yog qhov qub, tab sis nws tseem tsis tuaj yeem pib (relay 89 tsis qhib, qhov taw qhia lub teeb 89 raug kaw). Ua ntej, rov hais dua qhov qub ntawm qhov kev nyab xeeb Circuit Court 29. Peb tsis tuaj yeem xav tias qhov kev nyab xeeb Circuit Court yog qhov qub vim qhov taw qhia lub teeb 29 qhib. SPVF kev nyab xeeb Circuit Court yog ncaj qha nkag mus rau lub rooj tsavxwm P1 los ntawm kev hloov pauv thiab tam sim no txwv ntawm lub davhlau ya nyob twg 79. Yog li ntawd, qee zaum qis qis tuaj yeem nkag mus rau lub rooj tsavxwm P1, tsim qhov kev xav tsis tseeb tias qhov kev nyab xeeb Circuit Court yog qhov qub, tab sis qhov qis qis tsis tuaj yeem qhib relay 89. Yog li, yog tias luv luv hauv kev nyab xeeb Circuit Court tsis hnyav, nws yuav tsis ua rau lub fuse, tab sis yuav tsis ua rau lub fuse. Peb tuaj yeem ntsuas qhov tsis kam rau hauv av ntawm kev nyab xeeb Circuit Court thiab qhov hluav taws xob ntawm ntau lub ntsiab lus hauv kev nyab xeeb Circuit Court los txiav txim qhov teeb meem. Yog hais tias qhov kev ruaj ntseg Circuit Court yog ib txwm, ces xyuas seb tus pin W1C-P09 ntawm lub rooj tsavxwm P1 outputs ib tug tsawg voltage. Txij li cov zis taw tes ntawm lub rooj tsavxwm P1 yog yooj yim puas, tsuas yog xyuas cov zis transistor thiab thaiv ntawm board P1 feem ntau tuaj yeem pom qhov txhaum.
2. Ua haujlwm of the elevator
Lub elevator tuaj yeem ua haujlwm rau kev saib xyuas, txiav theem thiab rov qab mus rau qhov chaw nres tsheb hauv paus. Tag nrho cov kab hluav taws xob sab nraud yog qhov qub, tab sis serial LED (STM) ntawm P1 board tsis flashing, qhia txog kev ua haujlwm tsis zoo hauv cov kab ke. SPVF serial system muaj ob ceg: ib qho los ntawm chav tshuab mus rau sab nraud hu khawm, thiab lwm qhov los ntawm chav tshuab mus rau cov lus txib sab hauv thiab hauv pem teb. Serial system yuam kev feem ntau tshwm sim nyob rau hauv ntau txoj kev: ib qho kev ua yuam kev hauv pem teb txhais tau tias tsuas yog hauv pem teb tsis tuaj yeem hu; ob pem teb yuam kev txhais tau hais tias hu tsis tau ntawm cov ob pem teb no (vim hais tias lub system yuav kis tau bidirectionally); qee qhov yuam kev ua rau lub teeb hu lub teeb nyob twj ywm, thiab lub elevator cia li teb rau hauv pem teb; yuam kev nyob rau hauv lub tsheb manifest raws li cov lus txib teeb pom kev zoo rau txhua pem teb, thiab lub elevator nres ntawm txhua pem teb; lossis qhov taw qhia hauv pem teb tsis pom, thiab hauv pem teb tsis hloov. Cov no yog tag nrho cov cim qhia ntawm serial system yuam kev. Thaum cov teeb meem no tshwm sim, peb thawj zaug yuav tsum txheeb xyuas cov ceg twg yog qhov ua tsis raug raws li nws cov qauv, thiab tom qab ntawd nrhiav seb lub ntsiab lus twg yog qhov tsis raug, uas ua rau kho yooj yim dua. Qhov no serial system feem ntau muaj ob lub interface chips, UPA67C, ntawm lub P1 board, thiab ib co tam sim no limiting thiab voltage limiting circuits. Txhua lub thawv qhov rooj muaj ib qho kev sib xyaw ua ke, m5690 / m5226. Kuj tseem muaj m5690 thiab m5226 chips ntawm lub rooj sib tham hu thiab tso saib hauv lub tsheb. Cov no yog cov chips tseem ceeb ntawm no serial system.
