Kasi kuyowoyeskana kwa basi kwa CAN?
CAN CAN kuyowoyeskana
Malo gha Controller Area Network (CAN) ni basi yakudumbiskana yakulondezganako iyo yikugwiriskirika nchito mu mapulogiramu ghaunenesko gha - pa nyengo. Iwo ungatumizga vimanyikwiro mwakugwiliskira nchito twist - khebo, khebo ya coaxial, panji khebo ya fiber optic. Chifukwa cha kugwira ntchito kwake kwapachanya, kugomezgeka kwapachanya, na kugwira ntchito kwapachanya - nyengo, kwazgoka chimoza mwa mababu ghakugwiriskira ntchito chomene pa charu chose. CAN kuyowoyeskana ndiyo nthowa yikuru yakudumbiskana mu ndondomeko zakulongozgera mabatire (BMS). Iwo ŵakuzomerezgeka chomene mu ndondomeko zinandi za magesi gha BMS ghakupanga magesi gha BMS mu charu na pa charu chose, ndiposo mu vigaŵa vyakudumbiskana vya BMS vya mu charu na vya pa charu chose. Mabasi gha RS232 na RS485 ghakugwiriskirikaso nchito mu kudumbiskana kunyake kwa mukati mukati mwa ndondomeko za BMS.
Chithunzi 8{{7}26 chikulongora ndondomeko yakulongozgera mabatire gha basi ya magesi yakutowa. Pakati pawo, RS222 yikumanya chomene kuyowoyeskana pakati pa bolodi yikuru yakulaŵilira na kompyuta yakupokelera panji chipangizo cha mawoko, ndipo chikumalizga kuŵika vigaŵa vyakupambanapambana vya bolodi likuru la kulaŵilira na bolodi la kumanyikwa; RS485 chomenechomene ŵakumanya kuyowoyeskana pakati pa bolodi likuru la kulaŵilira na bolodi la kumanyikwa, na kumalizga kutumizga data ya batiri na vigaŵa vyakuwonera pakati pa master na matabwa gha ŵazga; CAN kuyowoyeskana kukugaŵika mu nthowa ziŵiri, CAN1 na CAN2. CAN1 chomenechomene yikudumbiskana na mulaŵiliri mukuru wa galimoto kuti wamalizge kuthandazgika kwa batire - dataal inmartment data iyo yikukhumbikwa na galimoto yose; CAN2 yikudumbiskana chomene na chida cha galimoto na charger iyo njambura kumanyikwa kuti yimanye kugaŵana kwa data ya mabatire na kupereka maziko gha data ghakulaŵilira.
Kapangidwe ka ndondomeko ya kalongozgiro ka mabatire (BMS) mu nthowa yakuchitira ntchito ya galimoto kakulongosoreka mu chithuzithuzi 8-27. Chigaŵa cha pakati cha BMS chikulongosora unenesko - nyengo na uthenga wakukhumbikwa wa batire ku mulaŵiliri wa galimoto na mulaŵiliri wa galimoto kwizira mu basi ya CAN1, kupangiska kuti ŵazomerezge nthowa zinandi zakulongozgera zakumanyikwa kuti ŵamalizge makora ntchito zakugwira ntchito na kutambasura umoyo wa batire. Pa nyengo yeneyiyo, BMS (chigaŵa cha kulongozga pakati) yikupharazga uthenga wakukwana wa mabatire ku ndondomeko ya kuwoneseska pa boti kwizira mu basi ya CAN2 yakuchimbira chomene, kulongora data ya umo batire yikuŵira na kupereka ma alamu ghakubudika, ntheura yikupereka fundo yakuti mabatire ghanozgeke na kusintha.
Kapangidwe ka BMS mu mtundu wa charging wa mwaluŵiro chikulongosoreka mu Chithunzi 8-28. Charger iyi yikukolerana mwakuthupi na galimoto ya magesi. Pa nyengo iyi, basi ya CAN2 yikulumikizga ku node ya charger, apo vinyake vikusintha yayi. Charger yikugwiriskira ncito basi yikuru yakukwera-speed CAN2 kuti yipulikiske umo batire likuŵira nyengo yeneco na kusintha ndondomeko ya kulipilira kuti yikwaniske kulipira mwakuvikilirika.
