DALYfeem ntau muaj peb txoj cai:Kev txhawb nqa CAN, UART/485, thiab Modbus.
1. CAN Protocol
Cov Cuab Yeej Ntsuas:Kev xeem CAN
- Tus nqi Baud:250K
- Hom Ncej:Cov Ncej Txheem thiab Cov Ncej Ntev. Feem ntau, cov Ncej Ntev yog siv, thaum cov Ncej Txheem yog rau ob peb lub BMS uas tau kho kom haum.
- Hom Kev Sib Txuas Lus:Cov ntaub ntawv ID txij li 0x90 txog 0x98cov neeg siv khoom siv tau. Lwm cov ID feem ntau cov neeg siv khoom siv tsis tau lossis hloov tsis tau.
- PC Software rau BMS: Qhov Tseem Ceeb + Cov Ntaub Ntawv ID + BMS Chaw Nyob + PC Software Chaw Nyob, piv txwv li, 0x18100140.
- BMS Teb rau PC Software: Qhov Tseem Ceeb + Cov Ntaub Ntawv ID + PC Software Chaw Nyob + BMS Chaw Nyob, piv txwv li, 0x18104001.
- Nco ntsoov qhov chaw ntawm PC Software Address thiab BMS Address. Qhov chaw nyob uas tau txais cov lus txib yuav tsum yog qhov ua ntej.
- Cov Ntaub Ntawv Txog Kev Sib Txuas Lus:Piv txwv li, nyob rau hauv lub roj teeb qhov teeb meem nrog rau kev ceeb toom thib ob ntawm qhov hluav taws xob qis tag nrho, Byte0 yuav tso tawm ua 80. Hloov mus rau binary, qhov no yog 10000000, qhov twg 0 txhais tau tias ib txwm thiab 1 txhais tau tias lub tswb. Raws li DALY lub ntsiab lus siab-sab laug, qis-sab xis, qhov no sib raug rau Bit7: kev ceeb toom thib ob ntawm qhov hluav taws xob qis tag nrho.
- Cov ID Tswj:Them MOS: DA, Tshem tawm MOS: D9. 00 txhais tau tias qhib, 01 txhais tau tias tawm.
2.UART/485 raws tu qauv
Cov Cuab Yeej Ntsuas:COM serial cuab yeej
- Tus nqi Baud:9600bps
- Hom Kev Sib Txuas Lus:Txoj Kev Xam Checksum:Daim checksum yog qhov sib sau ua ke ntawm tag nrho cov ntaub ntawv dhau los (tsuas yog qhov byte qis xwb).
- PC Software rau BMS: Frame Header + Communication Module Address (UPPER-Add) + Data ID + Data Length + Data Content + Checksum.
- BMSCov Lus Teb rau PC Software: Frame Header + Communication Module Address (BMS-Add) + Data ID + Data Length + Data Content + Checksum.
- Cov Ntaub Ntawv Txog Kev Sib Txuas Lus:Ib yam li CAN.
3. Modbus Protocol
Cov Cuab Yeej Ntsuas:COM serial cuab yeej
- Hom Kev Sib Txuas Lus:
- Hom Ntawv Teev Cov Lus:Nyeem Cov Npe, Thov Cov Ncej
- Byte: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7
- Kev piav qhia: 0xD2 | 0x03 | Chaw Nyob Pib | Tus lej ntawm Cov Npe Sau Npe (N) | CRC-16 Checksum
- Piv txwv li: D203000C000157AA. D2 yog qhov chaw nyob qhev, 03 yog qhov kev txib nyeem, 000C yog qhov chaw nyob pib, 0001 txhais tau tias tus lej ntawm cov npe sau kom nyeem yog 1, thiab 57AA yog CRC checksum.
- Tus Qauv Teb Lus Teb:
- Byte: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
- Kev piav qhia: 0xD2 | 0x03 | Qhov ntev ntawm cov ntaub ntawv | Tus nqi ntawm 1st Register | Tus nqi ntawm Nth Register | CRC-16 Checksum
- L = 2 * N
- Piv txwv li: N yog tus lej ntawm cov registers, D203020001FC56. D2 yog qhov chaw nyob qhev, 03 yog qhov nyeem cov lus txib, 02 yog qhov ntev ntawm cov ntaub ntawv nyeem, 0001 txhais tau tias tus nqi ntawm thawj zaug nyeem register, uas yog qhov xwm txheej tso tawm los ntawm tus tswv tsev hais kom ua, thiab FC56 yog CRC checksum.
- Hom Ntawv Teev Cov Lus:Nyeem Cov Npe, Thov Cov Ncej
- Sau Npe:Byte1 yog 0x06, qhov twg 06 yog cov lus txib kom sau ib qho kev sau npe, byte4-5 sawv cev rau tus tswv tsev hais kom ua.
- Tus Qauv Teb Lus Teb:Tus qauv teb rau kev sau ib daim ntawv teev npe tuav ib zaug ua raws li tib hom ntawv li tus qauv thov.
- Sau Ntau Cov Ntaub Ntawv Sau Npe:Byte1 yog 0x10, qhov twg 10 yog cov lus txib kom sau ntau lub npe sau cov ntaub ntawv, byte2-3 yog qhov chaw nyob pib ntawm cov npe sau, byte4-5 sawv cev rau qhov ntev ntawm cov npe sau, thiab byte6-7 sawv cev rau cov ntsiab lus ntawm cov ntaub ntawv.
- Tus Qauv Teb Lus Teb:Byte2-3 yog qhov chaw nyob pib ntawm cov registers, byte4-5 sawv cev rau qhov ntev ntawm cov registers.
