Data matut mahkai ladat ngu ai gaw hpa rai ta?
Bus Bus hte matut mahkai ai lam
Controller Area Network (CAN) Bus gaw, tengman ai- aten hta jai lang na matu galaw da ai serial matut mahkai ai lam hpe galaw ai Bus re. Dai gaw, n-gun n rawng ai pair, coaxial cable (sh) optical fiber ntsa na signal ni hpe htawn tsun lu ai. Shi a bungli galaw ai lam grai tsaw ai, kam hpa mai ai lam grai law ai, grai kaja ai tengman ai- aten a majaw, CAN gaw mungkan ting hta grau nna hkap la ai fieldbus langai mi tai wa sai.
Ya aten hta, CAN matut mahkai lam gaw battery hparan ai ladat (BMS) a matu madung matut mahkai ladat rai nga ai. Dai hpe mungdan kata hte mungkan ting na madang masat da ai wan jak battery ni hpe hparan ai ladat lahkawng yan hta, Miwa mung hte maigan mungdan ni hta mung, seng ang ai BMS data matut mahkai madang ni hta mung, ngang ngang kang kang tsun shadut nna, grai law hkra jai lang nga ai. Kaga Bus tara ni rai nga ai RS232 hte RS485 zawn re ai ni hpe mung, battery hparan ai ladat ni a kata lam matut mahkai lam nkau mi hta lang ai.
FlexRay Matut mahkai lam
Mawdaw hte seng ai hpaji masa hpe gyin shalat ai hte rau, htunghking CAN hparan ladat ni gaw mawdaw hte seng ai mayak mahkak ni hpe hparan na matu kaja dik ai lata la ai lam n rai sai. 2000 ning September shata hta, BMW hte DaimlerChrysler yan gaw, Philips hte Motorola ni hte pawng nna, FlexRay Consortium hpe hpaw nna, matut mahkai ladat nnan hpe gyin shalat nna, rawt jat galu kaba wa ai atsam marai, chassis, hte X{2}}wi wire system ni a matu, madang masat masa hku nna, n-gun jaw wa sai.
FlexRay gaw, htunghking hku nna, n-gun ja ai lam law law hpe jaw ya ai.
(1) Hkamja lam manu dan ai lamFlexRay channel shagu hta 10 Mbit/s ngu ai bandwidth hpe jaw da ai. FlexRay gaw, ya aten na CAN network ni a bungli galaw ai lawan dik htum hta grau law ai 20 Mbit/s-s-s-s-20 daram law ai transmission rate hpe lu la ai (CAN (sh) LIN network ni hte bung ai) shing nrai, dual{3}}channel system langai hku nna bungli galaw mai ai.
(2) Synchronized aten ladaw madungFlexRay hta lang ai access ladat gaw, mungkan ting na aten masat masa hpe madung tawn ai. Ndai aten hpe gaw, dai protocol hte maren, shi hkum shi gawgap nna, application layer hpe galaw da ai. Aten npawt nhpang a hkrak ai lam gaw 0.5 μs hte 10 μs (typically 1–2 μs) lapran rai nga ai.
(3) Deterministic matut mahkai lamFlexRay hta tsun shaga ai lam gaw, matut manoi bai kahtap tsun shaga ai lam ni hta byin pru wa ai, dai shara hta, laksan shiga ni hpe, shingjawng ai lam kata hta, masat da ai shara (slots) ni hpe jaw da ai. Dai majaw, shiga gara aten hta du wa na hpe hkap la ai wa gaw, tau hkrau chye da ai. Shiga du ai aten ni a aten ladaw n bung ai lam gaw grai kaji nna, kam hpa mai ai lam ni nga ai.
(4) Masu ai hpe hkam sharang ai lamN-gun ja ai shut ai lam hpe sawk sagawn lu ai atsam hte mara- hpe hkam sharang lu ai atsam gaw FlexRay hta ahkyak ai hkrang shapraw ai lam ni hpe myit yu ra ai.
- FlexRay bus gaw Cyclic Redundancy Check (CRC) hpe bungli galaw nna, matut mahkai lam hta shut ai lam ni hpe mu lu ai.
- Dual-channel matut mahkai lam hku nna, FlexRay gaw redundancy hpe jaw ya ai.
- Shagan topology (sh) topologies ni hpe kayau kaya lang ai hku nna, FlexRay gaw, mara n nga ai hpe hkum tsup hkra hparan ya lu ai, dai hta, langai sha rai nga ai{1}}point{3}} n-gun shayawm ai lam hpe shayawm ai lam ni lawm ai.
(5) flexibleFlexibility gaw FlexRay protocol hpe gyin shalat ai shaloi madung myit maju jung ai lam rai nna, lawu na lam ni hta dan dawng nga ai: ① Ngangum topologies law law hpe madi shadaw ai (bus, shagan, hybrid, etc.); Configurable message galu ai: data payload galu ai lam hpe control application a ra kadawn ai lam ni hte maren hkrak hkra galaw mai ai; ③ Dual-channel topology hpe lang ai shaloi, dai channel lahkawng hpe bandwidth hpe jat na matu (sh) n-gun n rawng ai shiga ni hpe htawn tsun na matu lang mai ai; ④ Matut mahkai lam langai a kata na static hte dynamic segment ni a aten ladaw hpe laksan application ra ai lam ni hte maren gram lajang mai ai.
Hpaga lam hta Ethernet
Industrial Ethernet gaw hkum tsup ai, hkum tsup ai digital network re. Hpaga galaw ai ni n bung ai ni kaw na device ni gaw, standard network protocol ni hpe hkan sa ai hku nna, shada da matut mahkai ai lam hpe loi loi hte lu la mai ai. Shi gaw matut mahkai lam grai law ai: Fast Ethernet gaw 10 Mbit/s hte 100 Mbit/s lawan ai hku hkap la ai majaw, Gigabit Ethernet hpaji masa rawt jat wa sai, 10 Gbit/s Ethernet gaw active sawk sagawn ai lam hte rawt jat galu kaba wa nga ai. Ndai manu ni gaw ya aten na fieldbus ni hta grau law ai.
Raitim, industrial Ethernet gaw yak hkak ai lam law law hpe naw hkrum sha nga ai, madung gaw:
- Tengman ai- aten hta galaw ai
- Grai sawng ai bungli galaw ai makau grup yin hta galai shai lu ai lam hte kam hpa mai ai lam
- Hpaga lam hta jai lang ai lam hpe hkang lu na matu htuk manu ai application-layer tara ni hpe lu la mai ai
Industrial Ethernet hpaji masa matut manoi rawt jat wa ai hte rau, lahta na lam ni hpe rawt jat galu kaba wa hkra hparan nga ai.
