Umklamo wesistimu yokushaja inqwaba ye-DC enezibhamu ezimbili

Lesi sihloko sezindaba sixoxa ngesakhiwo sikagesi se-inqwaba yokushaja ye-DC enezibhamu ezimbili, ichaza izimiso zokusebenza kwesibhamu esisodwa kanyeizinqwaba zokushaja izimoto zikagesi ezinezibhamu ezimbili, kanye nokuhlongoza isu lokulawula ukuphuma kokulinganisa kanye nokushintshana kokushajaisiteshi sokushaja esinezibhamu ezimbili.

Ukuze kuthuthukiswe ubuhlakani kanye nokuphendula ngesikhathi sangempela kokulawula ukushaja, lesi sihloko siphinde sikhulume ngohlelo lokuklama lwesistimu yokulawula inqwaba yokushaja olusekelwe ku-chip yokulawula eyinhloko ye-STM32F407 ene-core ye-Cortex M4 kanye nesistimu yokusebenza ye-FreeRTOS efakiwe.

Umklamo we-topology kagesi iyonke yama-pile okushaja

Umklamo Wezakhiwo

Lokhu okusha kwethula umklamo wesibhamu esikabiliIshaja ye-DC EV, equkethe isilawuli esiyinhloko, imojuli yamandla, isibonisi sesixhumi esibonakalayo somshini womuntu, isifundi sekhadi le-IC, imitha yamandla ehlakaniphile,I-contactor ye-AC, I-DC contactor, i-circuit breaker, i-surge protector, kanye nezinsiza ezimbili zikagesi ze-12V DC. Umdwebo kagesi ophelele wenqwaba yokushaja uboniswe ngezansi. Umklamo wokuxhuma kagesi phakathi kwenqwaba yokushaja kanye nezibhamu ze-A ne-B uhambisana nezinga likazwelonke lezindawo zokushaja ze-DC zamadivayisi okushaja okuqhubayo ezimotweni zikagesi.

Isimiso sokusebenza

Isiteshi sokushaja siyisibhamu esikabiliIsiteshi sokushaja se-DC, isebenzisa amamojula wamandla ayi-10 axhunywe ngokulingana, aklanywe ngezindlela ezimbili zokulawula ukushaja: ukushaja ngokulingana kanye nokushaja okuhleliwe.

Ukushaja ngokulingana: Zombili izibhamu u-A no-B zishaja ngesikhathi esisodwa, kanye namamojula wamandla angafika ku-5 ashaja kusuka kusibhamu ngasinye.

Ukushaja okuhleliwe: Uma isibhamu esisodwa kuphela sisebenza, amamojula wamandla angafinyelela ku-10 angashaja.

Amamojula kagesi athola okokufaka kwamandla e-AC kwezigaba ezintathu, okuxhunywe ku-surge protector, imitha yamandla e-AC yezigaba ezintathu, kanye ne-AC contactor. Amamojula kagesi akhipha amandla e-DC. Inkinobho yokumisa ephuthumayo nayo ifakiwe kokufakwayo, okuvumela ukuvikelwa kokumisa ephuthumayo ngokunqamula okokufaka kwezigaba ezintathu. Isilawuli esiyinhloko sixhumana namamojula kagesi ngebhasi le-CAN ukushintshanisa imiyalo yokulawula ukuphuma, kanti amamojula kagesi nawo axhunywe ngebhasi le-CAN. Isiteshi sinezinsiza ezimbili zikagesi ze-12V DC: esisodwa esixhunywe kumaphini e-A+ kanye ne-A- esibhamu sokushaja ukuze sinikeze amandla asekelayo aphansi emotweni kagesi, kanti esinye sivula isibonisi sesixhumi somuntu nomshini.

Umklamo wohlelo lokulawula oluyinhloko

A. Umdwebo Webhulokhi Lokusebenza Kwesistimu

Umdwebo oyinhloko webhulokhi yesistimu yokulawula uboniswe ngezansi. I-chip yokulawula eyinhloko yesistimu yi-STM32F407ZGT6, enezixhumi ezicebile ze-peripheral: 2 CAN, 4 USART, 2 UART, 1 Ethernet interface, njll., ezihlangabezana nezidingo eziyisisekelo ze-interface yesistimu yokulawula inqwaba yokushaja ukulawula izixhumi ezingaphandle ezifana namamojula wamandla, amamitha ahlakaniphile, izifundi zamakhadi e-IC, kanye nezikrini zokuthinta.

B. Umklamo Wesekethe Yehadiwe Yesistimu Yokulawula Eyinhloko

Lokhu kufaka phakathi ukwakheka kwamasekethe esibonakalayo sebhasi e-RS232, RS485, kanye ne-CAN.
