Software tiv thaiv lub tswv yim rau hluav taws xob compressors siv nyob rau hauv hluav taws xob tsheb
Cov tswv yim kev tiv thaiv ntawm hluav taws xob compressors yog qhia raws li cov kev ua tsis tau zoo ntawm cov hluav taws xob compressors. Lub hom phiaj ntawm tag nrho cov tswv yim kev tiv thaiv yog los tiv thaiv lub compressor los ntawm kev txo cov kev khiav hauj lwm lub hwj chim los yog kaw nyob rau hauv lub sij hawm thaum lub compressor ua hauj lwm txawv txav, thiab tiv thaiv lub compressor los ntawm kev puas tsuaj loj heev. Cov tswv yim kev tiv thaiv ntawm hluav taws xob compressors feem ntau suav nrog LIN / CAN kev sib txuas lus tiv thaiv, kev tiv thaiv kub, tiv thaiv overcurrent, tiv thaiv overvoltage thiab qis-kub preheating.
1. LIN/CAN kev sib txuas lus tiv thaiv
LIN / CAN kev tiv thaiv kev sib txuas lus txhais tau hais tias thaum muaj qhov yuam kev me ntsis, PID yuam kev, tsis muaj lus teb yuam kev, thav duab yuam kev, lub tsheb npav yuam kev, thiab lwm yam. ib lub sijhawm, lub compressor nres ua haujlwm tam sim ntawd. Thaum kev sib txuas lus rov qab mus rau qhov qub, lub compressor rov ua haujlwm li qub.
2. Kev tiv thaiv kub dhau
Kev tiv thaiv kub dhau txhais tau hais tias thaum lub tshuab hluav taws xob tswj xyuas pom tias tus nqi IGBT kub siab dhau los yog qis dhau (tshaj qhov ntsuas kub ntawm qhov ntsuas kub), tus maub los tau tshaj tawm qhov ua txhaum ntawm IGBT kub, thiab lub compressor kaw hauv teb. Thaum qhov kub thiab txias rov qab los ntawm qhov ntsuas kub thiab lub sijhawm kaw ntau dua li lub sijhawm teem, lub compressor yuav teb rau lub tsheb xav tau dua. Lub hom phiaj ntawm kev tiv thaiv no yog kom tsis txhob muaj kev puas tsuaj rau IGBT los ntawm kev ua haujlwm dhau ntawm nws qhov kub thiab txias. Txhawm rau zam qhov tsis ua haujlwm ntawm qhov ntsuas kub ntsuas ntsuas qhov ntsuas IGBT, ob lub ntsuas kub ntsuas feem ntau tau muab tso rau hauv tus tswj hwm tib lub sijhawm. ECU siv qhov ntsuas kub siab dua qhov ntsuas qhov ntsuas raws li qhov ntsuas kub. Nyob rau tib lub sijhawm, qhov ntsuas kub ntawm ob qhov ntsuas kub yuav raug muab piv rau lub sijhawm. Thaum qhov tseeb tus nqi sib txawv ntawm ob tshaj qhov ntsuas kub, lub compressor yuav qhia txog qhov kub thiab txias sensor rationality txhaum.
3. Kev tiv thaiv overcurrent
Lub hom phiaj ntawm kev tiv thaiv overcurrent yog los tiv thaiv cov khoom hluav taws xob sab hauv ntawm lub compressor los ntawm kev puas tsuaj vim overcurrent. Kev tiv thaiv overcurrent suav nrog kev tiv thaiv tsheb npav tam sim no thiab theem tam sim no. Kev tiv thaiv lub tsheb npav tam sim no yog hais txog kev txwv cov khoom siv tam sim no rau qee tus nqi. Thaum nws tshaj tus nqi teev, lub compressor yuav nres. Kev tiv thaiv theem tam sim no yog los tiv thaiv IGBT los ntawm kev puas tsuaj. Rau hluav taws xob compressors, theem tam sim no ncaj qha cuam tshuam nrog lub compressor load. Qhov ntau dua qhov load, qhov ntau dua cov theem tam sim no, yog li cov theem tam sim no kuj tseem siv tau los ua ib qho kev tiv thaiv overload. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv IGBT zoo dua thiab tiv thaiv nws los ntawm kev ua haujlwm nyob rau hauv qhov siab tam sim no thiab kub siab rau lub sijhawm ntev, kev tiv thaiv theem tam sim no yuav cuam tshuam nrog kev tiv thaiv kub. Thaum qhov kub ntawm IGBT qis, theem tam sim no kub txwv tsis hloov. Thaum qhov kub ntawm IGBT Ntawm qhov muaj nuj nqis siab dua, theem tam sim no txwv txo qis nrog IGBT kub kom txog thaum IGBT tiv thaiv kub dhau.
4. Kev tiv thaiv overvoltage
Kev tiv thaiv overvoltage yog hais txog kev tiv thaiv qhov twg qhov voltage tshaj qhov ua haujlwm ntau thiab txwv qhov compressor ceev los yog kaw. Kev tiv thaiv overvoltage tau muab faib ua kev tiv thaiv hluav taws xob siab thiab kev tiv thaiv tsis tshua muaj hluav taws xob. Tsawg-voltage tiv thaiv yog muab faib ua 12 V voltage tiv thaiv thiab 15 V tsav voltage tiv thaiv. Kev tiv thaiv hluav taws xob siab yog txhawm rau tiv thaiv cov khoom sab hauv ntawm tus maub los los ntawm kev tawg vim yog qhov hluav taws xob ntau dhau. Nyob rau tib lub sijhawm, thaum lub input voltage tsawg dhau, lub zog compressor tsis tuaj yeem ua tau raws li qhov xav tau, thiab compressor ua haujlwm nrog lub zog tsawg. Kev them nqi hluav taws xob ntawm cov pawg them tam sim no nyob rau hauv kev ua lag luam tsis ruaj khov, thiab muaj cov hluav taws xob siab tam sim no. Yog li ntawd, compressor overvoltage tiv thaiv feem ntau suav nrog software tiv thaiv thiab kho vajtse tiv thaiv. Kev tiv thaiv software tiv thaiv ms-theem instantaneous high voltages, thaum kho vajtse tiv thaiv tuaj yeem ntes peb theem instantaneous high voltage, kev sib xyaw ntawm software thiab kho vajtse tiv thaiv tuaj yeem tiv thaiv lub compressor los ntawm IGBT tawg los ntawm high voltage. Txhawm rau tiv thaiv qhov tsis ua haujlwm ntawm lub siab-siab sensor, ob lub siab-siab sensors feem ntau yog teem rau hauv tus maub los. Lub compressor maub los yuav tsis tu ncua sib piv qhov sib txawv ntawm ob lub siab-siab sensors. Thaum qhov sib txawv tshaj qhov teeb tsa, lub compressor yuav tsum tsis ua haujlwm. Thaum tus maub los kuaj pom tias lub tsheb npav high-voltage voltage fluctuates zoo heev, piv txwv li, thaum nws pom tias qhov sib txawv ntawm ob qhov hluav taws xob qhov tseem ceeb tshaj li cov nqi teev nyob rau hauv ib lub sij hawm coj mus kuaj, lub compressor yuav khiav ntawm ib tug txo hwj chim. Thaum lub zog hloov pauv rov qab mus rau hauv qhov txwv tus nqi, lub compressor yuav rov pib ua haujlwm lub hom phiaj ceev.
