Igishushanyo mbonera cya sisitemu yo gusharija DC ifite imbunda ebyiri

Iyi nkuru ivuga ku miterere y'amashanyarazi yaikirundo cyo gusharija DC gifite imbunda ebyiri, gusobanura amahame y'imikorere y'imbunda imwe n'iy'imbunda imweimodoka zikoresha amashanyarazi zirimo imbunda ebyiri zisharija, no gutanga ingamba zo kugenzura umusaruro mu kuringaniza no gusimburanya ubwishyu bwasitasiyo yo gusaruriraho imbunda ebyiri.

Kugira ngo inoze ubwenge n'uburyo bwo gusubiza mu buryo bwihuse ibijyanye no kugenzura gusharija, iyi nkuru inavuga ku gishushanyo mbonera cya sisitemu yo kugenzura ubwinshi bw'amakuru ishingiye kuri chip ya STM32F407 igenzura ifite core ya Cortex M4 na sisitemu y'imikorere ya FreeRTOS.

Igishushanyo mbonera cy'imiterere rusange y'amashanyarazi y'imirongo yo gusharija

Igishushanyo mbonera cy'ubwubatsi

Iyi nshya igaragaza igishushanyo mbonera cy'imbunda ebyiriShajara ya DC EV, igizwe n'icyuma gipima ingufu, module y'amashanyarazi, ecran y'aho umuntu ahurira n'imashini, igikoresho gisoma ikarita ya IC, icyuma gipima ingufu gikoresheje ubwenge,Kontakteri ya AC, Kontakteri ya DC, icyuma gica amashanyarazi, icyuma kirinda umuvuduko w'amashanyarazi, n'ibikoresho bibiri by'amashanyarazi bya 12V DC. Ishusho rusange y'amashanyarazi y'ikirundo cyo gusharija igaragara hepfo. Igishushanyo mbonera cy'amashanyarazi hagati y'ikirundo cyo gusharija n'imbunda za A na B gihuye n'ibipimo ngenderwaho by'igihugu byo gushyiramo DC charger surgery surges ku binyabiziga by'amashanyarazi.

Ihame ry'imikorere

Aho bashyira umuriro ni imbunda ebyiriSitasiyo yo gushyushya ya DC, ikoresha module 10 z'amashanyarazi zihujwe icyarimwe, zakozwe mu buryo bubiri bwo kugenzura gusharija: gusharija kuringaniza no gusharija mu buryo butambitse.

Gusharija kuringaniza: Imbunda zombi A na B zisharija icyarimwe, hamwe n'ingufu zitarenze eshanu zisharija kuri buri mbunda.

Gushaja mu buryo butunguranye: Iyo imbunda imwe gusa ikora, modules 10 z'amashanyarazi zishobora gusaja.

Imashini z'amashanyarazi zakira ingufu za AC z'ibice bitatu, zihujwe n'icyuma gikingira umuvuduko, icyuma gipima ingufu za AC cy'ibice bitatu, na contactor ya AC. Imashini z'amashanyarazi zisohora ingufu za DC. Hari kandi akabuto ko guhagarika byihutirwa mu kwinjira, gatuma habaho uburinzi bwo guhagarika byihutirwa binyuze mu guca icyuma gipima ibice bitatu. Imashini igenzura amashanyarazi ikorana na mashini z'amashanyarazi binyuze muri bisi ya CAN kugira ngo ihererekanye amabwiriza yo kugenzura umusaruro, kandi mashini z'amashanyarazi nazo zihujwe binyuze muri bisi ya CAN. Iyi sitasiyo ifite amashanyarazi abiri ya 12V DC: imwe ihujwe na A+ na A- pin z'imbunda yo gusharija kugira ngo itange ingufu z'amashanyarazi ziciriritse, n'indi ikoresha ecran ihuza mashini n'abantu.

Igishushanyo mbonera cya sisitemu y'ibanze yo kugenzura

A. Ishusho y'imikorere ya sisitemu

Ishusho nyamukuru ya sisitemu yo kugenzura iragaragara hepfo. Chip nyamukuru yo kugenzura ya sisitemu ni STM32F407ZGT6, ifite imiyoboro myinshi ya peripheral: 2 CAN, 4 USART, 2 UART, 1 Ethernet interface, nibindi, byujuje ibisabwa by'ibanze bya sisitemu yo kugenzura pile control kugira ngo igenzure imiyoboro nka modules z'amashanyarazi, meteres za smart, readers za card za IC, na ecran zo gukoraho.

B. Igishushanyo mbonera cy'uruziga rw'ibikoresho by'ingenzi

Ibi birimo igishushanyo mbonera cy’imiyoboro ya bisi ya RS232, RS485, na CAN.
