Thaum caij tsheb hauv of the elevator, koj twv yuav raug hu xav tau los ntawm ib chav mus rau lwm qhov zoo thiab nyab xeeb. Hauv of the elevator tsav, nrawm nroos txhawb nqa cov elevator mus nres ntawm txoj haujlwm tshwj xeeb thiab decelerate yooj yim txog thaum nws los nres. Tsis muaj cov kev tswj txav tau yooj yim tuaj yeem ua rau muaj lub elevator mus yuam kev ntawm cov plag tsev, uas tuaj yeem ua rau lub elevator ridzy thiab tsis xis nyob lossis tsis nyab xeeb.
Cov neeg hlau, khoos phis tawj suav (cnc)
Ntau yam ntawm kev tsav tsheb yog qhov tseem ceeb hauv kev ua kom tiav qhov kev tswj hwm qhov kev tswj hwm hauv kev tswj hwm hauv lub sijhawm tiag tiag, kev siv, thiab tsav tsheb. Daim ntawv no yuav tham txog cov piv txwv ntawm cov thev naus laus zis uas txhawb nqa txhua subsystem.

Kev tswj hwm qhov tseeb tsis muaj peev xwm tswj tsis tau yog tsis muaj qhov tseeb txoj hauj lwm thiab kev pom zoo. Hnov tuaj yeem suav nrog lub cev muaj zog countular txoj hauj lwm thiab cov ceevfaj sensing lossis conveyor siv txoj hauj lwm tawm thiab nrawm. Cov neeg tsim qauv feem ntau siv inremental optical optical encoders nrog ntau pua mus rau ib txhiab slots ib lub kiv puag ncig kom paub txoj hauj lwm thiab nrawm. Cov encoders no feem ntau txuas nrog microcontrollers (Mcus) ntawm quap) thiab yog li ntawd xav tau kom muaj QEP interface muaj peev xwm.
Qhov uas muaj tseeb, los ntawm kev sib piv, feem ntau muaj ntau dua, thiab yog qhov tseeb rau kev hloov pauv ntawm Angular. Txoj haujlwm tsis hnov tau hloov pauv mus rau cov digital sawv cev thiab encoded raws li tus qauv qauv. Piv txwv ntawm cov txheej txheem no yog T-format thiab GMGA) rau lub GATE Programstly (FPGA) rau cov encoder, tab sis ntau thiab ntau dua mcus Tam sim no muaj lub peev xwm no (raws li qhia hauv daim duab 1 hauv qab). Vim tias t-hom thiab biss c protricols feem ntau sib txawv ntawm cov kev txhawb nqa los ntawm cov neeg sib txuas lus tsis zoo xws li SERIPY Feem ntau MCUs, lawv feem ntau xav tau customizable logic thaiv lossis cov tswv cuab ua haujlwm.
Ntawm qhov chaw encoding tseem tuaj yeem ua raws cov tshuab hluav taws xob lossis kev daws teeb meem zoo li hluav taws xob, uas yuav tsum tau ntsuas hluav taws xob sinusoidal. Precision operational operational uaplifiers thiab voltage refence yog li tseem ceeb. Lub cev muaj zog thiab tsa suab tswj ib txwm yuav tsum muaj lub cev muaj zog tam sim no thiab cov hluavtaws nrhiav tau, tshwj xeeb tshaj yog thaum lub siab tswj tau siv. Cov kev daws teeb meem muaj nyob hauv nroog thiab inverter Choj
Tab tom ua
Kev Tawm Tsam Kev Tawm Tsam thiab Algorithms nyob rau hauv lub zog txav chaw xav tau kev pab ntev nrog ib txwm muaj kev txhawb nqa kom muaj qhov tsim nyog thiab qhov tseeb Cov. Ntau Mcus muaj cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob kom hnyav rau ntawm trigonometric, logarithmic thiab exponentialially ua lej.
Muab cov naj npawb ntawm cov lus tsa suab raws li kev tswj hwm lossis cov neeg tsim qauv tswj hwm feem ntau siv cov txheej txheem ntau (CPU) architecture lossis CPU-zoo li cov pa roj popals. Ntau CPUs tseem tuaj yeem raug txiav txim siab rau kev saib xyuas ntxiv thiab kev sib txuas lus.
Raws li lub sijhawm tswj hwm tiag tiag, tag nrho cov teeb liab ntawm tag nrho cov teeb liab txoj saw (piv txwv li ntawm kev hloov tshiab ntawm cov kev tswj hwm ntawm kev tswj hwm kev tswj hwm , thiab yog li ntawd ntawm qhov tseeb. Qee qhov Mcus muaj on-chip analog cov sib piv uas tuaj yeem tsim kev tswj hwm ncaj qha, txo qis latency thiab CPU thauj khoom. Kev qhia nrawm thiab kev txuag nyiaj thiab rov qab tseem yog qhov tseem ceeb.
Kev ua haujlwm siab yog tsis txaus. Tsab ntawv tsa suab McUs yuav tsum muaj General-lub hom phiaj tswj lub zog xws li {}}}} kub} ) tawm. Lub peev xwm los siv kev cai kev cai thiab sijhawm yuav tsum muaj.
Txhawm rau pab cov neeg tsim qauv tau sawv thiab khiav thiab qhib lawv tus qauv tsim nrawm dua, nrog cov neeg tsav tsheb thiab cov chaw qiv nyiaj, nrog rau kev tswj hwm tus kheej nrog GUI Configurability.
Mcus rau kev tsav tsheb
Cov tsav tsheb
Cov cuab yeej siv hluav taws xob thiab cov tsav tsheb yuav tsum tau muab cov kev txiav txim siab xav tau, feem ntau yog nyob rau hauv daim ntawv ntawm PWM, qhov kev ua lub luag haujlwm sawv cev rau kev nqis tes ua. Kev tswj hwm kev tswj ntawm lub PWM Pulses yog qhov tseem ceeb, lub ntsiab lus uas tus tsav tsheb yuav tsum tau siv qhov me me ua haujlwm sib txawv; Lub hwj chim ntaus ntawv yuav tsum tig thiab tawm ntawm lub sijhawm npaj. Cov tsav tsheb zoo li no tau yooj yim muaj muaj hnub no, nrog cov nta ntxiv xws li overcurrent thiab thermal tiv thaiv. New dav bandgap fais fab cuab yeej ua kom sai thiab meej lem tig-rau thiab tig-tawm sijhawm. Cov nrawm nrawm nrawm thiab qis hloov cov khoom poob ntawm cov khoom siv bandgap ntau kuj siv cov tshuaj tswj kom ceev ceev rau kev txhim kho kev ruaj ntseg thiab kev ua tau zoo.
Ntxiv rau qhov raug, ntau cov ntawv thov kom muaj kev tsim muaj zog tsim uas tau cog lus txaus los siv cov tsav tsheb nrog kev hnov zoo tam sim no thiab lub zog muab hluav taws xob hloov kho.
