Eli nqaku leendaba lixoxa ngesakhiwo sombane se-inqwaba yokutshaja ye-DC enemipu emibini, icacisa imigaqo yokusebenza kwe-single-gun kunyeiinqwaba zokutshaja zezithuthi zombane ezinemipu emibini, kunye nokucebisa icebo lokulawula imveliso yokulinganisa kunye nokutshintshana kokutshajaisikhululo sokutshaja esinemipu emibini.
Ukuphucula ubukrelekrele kunye nempendulo yexesha langempela yolawulo lokutshaja, eli nqaku likwakhankanya iskimu soyilo lwenkqubo yokulawula iipali zokutshaja esekelwe kwitshiphu yokulawula ephambili ye-STM32F407 enesiseko seCortex M4 kunye nenkqubo yokusebenza yeFreeRTOS efakiweyo.
Uyilo lwe-topology yombane iyonke yeenqwaba zokutshaja
Uyilo lweZakhiwo
Le intsha ibonakalisa uyilo lwe-dual-gunItshaja ye-DC EV, equka isilawuli esiphambili, imodyuli yamandla, isibonisi sojongano lomntu nomatshini, isifundi sekhadi le-IC, imitha yamandla ekrelekrele,Isixhobo soqhagamshelwano lwe-AC, Isixhobo soqhagamshelwano seDC, i-circuit breaker, i-surge protector, kunye nezixhobo zombane ezimbini ze-12V DC. Umzobo wombane opheleleyo wenqwaba yokutshaja uboniswe ngezantsi. Uyilo loqhagamshelo lombane phakathi kwenqwaba yokutshaja kunye neembumbulu ze-A kunye ne-B luhambelana nomgangatho wesizwe we-DC charging interfaces zezixhobo zokutshaja eziqhubayo kwizithuthi zombane.
Umgaqo wokusebenza
Isikhululo sokutshaja sisixhobo sompu esiphindwe kabiniIsikhululo sokutshaja seDC, isebenzisa iimodyuli zamandla ezili-10 ezidityaniswe ngaxeshanye, eziyilwe ngeendlela ezimbini zokulawula ukutshaja: ukutshaja ngokulinganayo kunye nokutshaja okuhleliweyo.
Ukutshaja ngokulinganayo: Zombini izibhamu u-A no-B zitshaja ngaxeshanye, kunye neemodyuli zamandla ezi-5 ezitshaja kwisibhamu ngasinye.
Ukutshaja okungaguqukiyo: Xa umpu omnye kuphela usebenza, iimodyuli zamandla ezili-10 zingatshaja.
Iimodyuli zamandla zifumana igalelo lamandla e-AC lamanqanaba amathathu, eliqhagamshelwe kwisikhuseli sokushushuza, imitha yamandla e-AC yamanqanaba amathathu, kunye nesixhobo sokudibanisa i-AC. Iimodyuli zamandla zikhupha amandla e-DC. Iqhosha lokumisa ngongxamiseko likwafakiwe kwigalelo, okuvumela ukhuseleko lokumisa ngongxamiseko ngokunqumla igalelo lamanqanaba amathathu. Umlawuli oyintloko unxibelelana neemodyuli zamandla ngebhasi ye-CAN ukuze kutshintshiselwane imiyalelo yokulawula ukuphuma, kwaye iimodyuli zamandla nazo ziqhagamshelwe ngebhasi ye-CAN. Isikhululo sinezixhobo zamandla ezimbini ze-12V DC: esinye siqhagamshelwe kwiiphini ze-A+ kunye ne-A zesibhamu sokutshaja ukubonelela ngamandla ancedisayo aphantsi kwisithuthi sombane, kwaye esinye sinikezela amandla kwisibonisi sojongano lomatshini womntu.
Uyilo lwenkqubo yolawulo oluphambili
A. Umzobo weBloko yoMsebenzi weNkqubo
Umzobo oyintloko webhloko yenkqubo yokulawula uboniswe ngezantsi. Itshiphu yokulawula ephambili yenkqubo yi-STM32F407ZGT6, eneendawo zokunxibelelanisa ezityebileyo: ii-CAN ezimbini, ii-USART ezi-4, ii-UART ezi-2, ii-Ethernet ezi-1, njl.njl., ezihlangabezana neemfuno ezisisiseko zenkqubo yokulawula iipali zokutshaja ukulawula izinto ezisetyenziswa kwi-peripheral ezifana neemodyuli zamandla, iimitha ezikrelekrele, izifundi zekhadi le-IC, kunye nezikrini zokuchukumisa.
B. Uyilo lweSekethe yeHardware yeNkqubo yoLawulo oluPhambili
Oku kuquka uyilo lweesekethe ze-bus interface ze-RS232, RS485, kunye ne-CAN.
Uyilo lwe-RS232 Interface
