E matapakihia ana e tēnei tuhinga pūrongo te hanganga hiko o tētahipuranga utu DC pū-rua, te whakamārama i ngā mātāpono mahi o te pū kotahi me tepuranga utu waka hiko pū-rua, me te whakaaro i tētahi rautaki whakahaere putanga mō te whakataurite me te utu tauutuutu oteihana utu pū rua.
Hei whakapai ake i te mōhiotanga me te urupare wā-tūturu o te whakahaere utu, ka whakahuatia hoki i roto i tēnei tuhinga tētahi kaupapa hoahoa mō tētahi pūnaha whakahaere puranga utu e hangai ana ki te maramara whakahaere matua STM32F407 me te matua Cortex M4 me te pūnaha whakahaere FreeRTOS kua whakauruhia.
Te hoahoa o te āhua hiko whānui o ngā pou utu
Hoahoa Whare
Kei roto i tēnei mea hou tētahi hoahoa mō tētahi pū-ruaRīhi EV DC, kei roto ko te kaiwhakahaere matua, te waeine hiko, te whakaaturanga atanga tangata-mīhini, te kaipānui kāri IC, te mita pūngao atamai,Kaiwhakapā AC, Whakawhiti DC, te whati hiko, te parenga ngaru, me ngā pū hiko DC 12V e rua. Kei raro nei te hoahoa hiko whānui o te puranga utu. Ko te hoahoa hononga hiko i waenga i te puranga utu me ngā pū A me B e rite ana ki te paerewa ā-motu mō ngā atanga utu DC o ngā taputapu utu hiko mō ngā waka hiko.
Te kaupapa mahi
He pū rua te teihana utuTeihana utu DC, e whakamahi ana i ngā waeine mana 10 e honoa whakarara ana, i hangaia me ngā aratau whakahaere utu e rua: te utu taurite me te utu taurite.
Te utu ōrite: Ka utu ngātahi ngā pū A me B, me te mōrahi o te 5 ngā waeine mana ka utuhia mai i ia pū.
Te utunga taupatupatu: Ina kotahi anake te pū e whakahaerehia ana, e 10 ngā waeine mana ka taea te utu.
Ka whiwhi ngā kōwae hiko i te tāuru hiko AC-wāhanga-toru, e hono ana ki te parenga ngaru, ki te mita pūngao AC-wāhanga-toru, me te whakapā AC. Ka whakaputahia e ngā kōwae hiko te hiko DC. Kei roto hoki he pātene mutu ohorere i te tāuru, e āhei ai te tiaki mutu ohorere mā te tapahi i te tāuru-wāhanga-toru. Ka kōrero te kaiwhakahaere matua ki ngā kōwae hiko mā te pahi CAN hei whakawhiti whakahau whakahaere putanga, ā, ka honoa hoki ngā kōwae hiko mā te pahi CAN. E rua ngā pūtake hiko DC 12V o te teihana: kotahi e hono ana ki ngā pine A+ me A- o te pū utu hei whakarato hiko āwhina iti-ngaohiko ki te waka hiko, ā, ko tētahi e whakakaha ana i te whakaaturanga atanga tangata-mīhini.
Te hoahoa o te pūnaha whakahaere matua
A. Kauwhata Poraka Mahi Pūnaha
Kei raro nei te hoahoa poraka pūnaha whakahaere matua. Ko te maramara whakahaere matua o te pūnaha ko STM32F407ZGT6, he maha ngā atanga taha: 2 CAN, 4 USART, 2 UART, 1 atanga Ethernet, me ētahi atu, e tutuki ana i ngā whakaritenga atanga taketake o te pūnaha whakahaere puranga utu hei whakahaere i ngā taha taha pēnei i ngā kōwae hiko, ngā mita atamai, ngā kaipānui kāri IC, me ngā mata pa.
B. Hoahoa Porowhita Taputapu Pūnaha Whakahaere Matua
Kei roto i tēnei ko te hoahoa o ngā ara iahiko atanga pahi mō te RS232, RS485, me te CAN.
Hoahoa Atanga RS232
Hoahoa Atanga RS485
Hoahoa Atanga CAN
