DALYFeem ntau muaj peb txoj cai:CAN, UART/485, thiab Modbus.
1. CAN raws tu qauv
Test Tool:CANtest
- Baud Rate:250k ua
- Frame Hom:Standard thiab Extended Frames. Feem ntau, Cov Ncauj Lus Ntxiv yog siv, thaum lub Standard Ncej yog rau ob peb customized BMS.
- Kev sib txuas lus hom:Cov ntaub ntawv ID los ntawm 0x90 txog 0x98yog siv tau rau cov neeg siv khoom. Lwm cov IDs feem ntau tsis siv tau lossis hloov tau los ntawm cov neeg siv khoom.
- PC Software rau BMS: Qhov Tseem Ceeb + Cov Ntaub Ntawv ID + BMS Chaw Nyob + PC Software Chaw Nyob, xws li 0x18100140.
- BMS Teb rau PC Software: Qhov Tseem Ceeb + Cov Ntaub Ntawv ID + PC Software Chaw Nyob + BMS Chaw Nyob, xws li 0x18104001.
- Nco ntsoov txoj haujlwm ntawm PC Software Chaw Nyob thiab BMS Chaw Nyob. Qhov chaw nyob tau txais cov lus txib los ua ntej.
- Kev sib txuas lus Cov ntsiab lus:Piv txwv li, nyob rau hauv cov teeb meem roj teeb nrog ib tug thib ob ceeb toom ntawm tsis tshua muaj voltage tag nrho, Byte0 yuav tso saib raws li 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 siab-sab laug, qis-txoj cai txhais, qhov no sib raug rau Bit7: kev ceeb toom theem nrab ntawm qhov tsis tshua muaj hluav taws xob tag nrho.
- Tswj IDs:Them nyiaj MOS: DA, Tshem tawm MOS: D9. 00 txhais tau tias yog, 01 txhais tau tias tawm.
2.UART/485 raws tu qauv
Test Tool:COM serial cuab tam
- Baud Rate:9 600bps
- Kev sib txuas lus hom:Checksum Calculation Method:Cov checksum yog cov lej ntawm tag nrho cov ntaub ntawv dhau los (tsuas yog qhov tsawg byte xwb).
- PC Software rau BMS: Ncej Header + Kev Sib Txuas Lus Module Chaw Nyob (UPPER-Ntxiv) + Cov Ntaub Ntawv ID + Cov Ntaub Ntawv Ntev + Cov Ntsiab Lus Cov Ntaub Ntawv + Checksum.
- BMS Teb rau PC Software: Ncej Header + Kev Sib Txuas Lus Module Chaw Nyob (BMS-Ntxiv) + Cov Ntaub Ntawv ID + Cov Ntaub Ntawv Ntev + Cov Ntaub Ntawv Cov Ntsiab Lus + Checksum.
- Kev sib txuas lus Cov ntsiab lus:Ib yam li CAN.
3. Modbus raws tu qauv
Test Tool:COM serial cuab tam
- Kev sib txuas lus hom:
- Message Protocol Format:Nyeem Sau Npe, Thov Ncej
- Byte: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7
- Description: 0xD2 | 0 x03; Pib Chaw Nyob | Number of Registers (N) | CRC-16 Checksum
- Piv txwv li: D203000C000157AA. D2 yog tus qhev chaw nyob, 03 yog cov lus txib nyeem, 000C yog qhov chaw pib, 0001 txhais tau tias cov ntawv sau npe nyeem yog 1, thiab 57AA yog CRC checksum.
- Standard Teb Ncej:
- Byte: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
- Description: 0xD2 | 0 x03; Cov ntaub ntawv ntev | Tus nqi ntawm 1st Register | Tus nqi Nth Register | CRC-16 Checksum
- L = 2 * N
- Piv txwv li: N yog tus naj npawb ntawm cov npe, D203020001FC56. D2 yog tus qhev chaw nyob, 03 yog cov lus txib nyeem, 02 yog qhov ntev ntawm cov ntaub ntawv nyeem, 0001 txhais tau hais tias tus nqi ntawm qhov kev sau npe thib 1 nyeem, uas yog qhov tso tawm los ntawm tus tswv tsev hais kom ua, thiab FC56 yog CRC checksum.
- Message Protocol Format:Nyeem Sau Npe, Thov Ncej
- Sau npe:Byte1 yog 0x06, qhov twg 06 yog cov lus txib los sau ib qho kev tuav npe, byte4-5 sawv cev rau tus tswv tsev hais kom ua.
- Standard Teb Ncej:Cov txheej txheem teb tus qauv rau kev sau ib daim ntawv tuav pov hwm ua raws tib hom ntawv raws li daim ntawv thov.
- Sau ntau cov ntaub ntawv sau npe:Byte1 yog 0x10, qhov twg 10 yog cov lus txib kom sau ntau cov ntaub ntawv sau npe, byte2-3 yog qhov chaw pib ntawm cov npe, byte4-5 sawv cev qhov ntev ntawm cov npe, thiab byte6-7 sawv cev cov ntaub ntawv cov ntsiab lus.
- Standard Teb Ncej:Byte2-3 yog qhov chaw nyob pib ntawm cov npe, byte4-5 sawv cev qhov ntev ntawm cov npe.
