Unyuze ku cyambu ku bwato ubwo aribwo bwose bugezweho, uzasangamo ubwato aho chartplotter yerekana amakuru ya moteri, autopilot igasoma sensor y'umuyaga, kandi bateri igenzura uko ihagaze ku cyuma cyerekana amashanyarazi - hose ku mugozi umwe unyura mu bwato. Ikoranabuhanga riri inyuma y'ubwo buryo ni NMEA 2000®, protocole y'itumanaho yabaye ururimi rusanzwe rw'ibikoresho by'ikoranabuhanga byo mu mazi.
Iyi mfashanyigisho isobanura uburyo protocole ya NMEA 2000 ikora: umuyoboro ikoresha, sisitemu y'ubutumwa ikoresha, uburyo ibikoresho byinjira mu muyoboro, n'icyo bisaba kugira ngo sisitemu ya bateri ya lithium yinjiremo. Waba uteganya kuvugurura ibikoresho by'ikoranabuhanga cyangwa ugaragaza ibisabwa mu itumanaho ku mushinga wa bateri ya OEM, gusobanukirwa protocole ni intambwe ya mbere igana kuri sisitemu aho byose bivuga ku bindi byose.
NMEA 2000 ni iki?
NMEA 2000 ni porotokoli y’itumanaho isanzwe yemerera ibikoresho by’ikoranabuhanga byo mu mazi — ecran, sensors, moteri, na bateri — gusangira amakuru ku muyoboro umwe. Yakozwe n’Ishyirahamwe ry’Igihugu ry’Ikoranabuhanga mu by’Imari, yubakiye ku ikoranabuhanga rya CAN bus (Controller Area Network) kandi yemerera ibikoresho biva mu nganda zitandukanye guhanahana amakuru nta nsinga zihariye hagati ya buri bikoresho.
NMEA 2000® ni ikirango cyanditswe cy’Ishyirahamwe ry’Igihugu ry’Ibyerekeye Electronics zo mu Nyanja (NMEA), ikigo gikorera muri Amerika giteza imbere kandi kigakomeza amahame ngenderwaho y’ibikoresho byo mu mazi. Iyi porotokoli igena umuyoboro uhendutse, uhuza impande zombi, uhuza abantu benshi, kandi uhuza abantu benshi: igikoresho icyo ari cyo cyose cyemewe gishobora kohereza no kwakira amakuru, umuyoboro urayishyiraho, kandi nta mugenzuzi mukuru ushingiyeho byose.
Iyo ngingo ya nyuma ifite agaciro kurusha uko isa. Ku muyoboro wa NMEA 2000, iyo igikoresho kimwe cyananiwe, ibisigaye bikomeza kuvugana. Gereranya ibyo n'insinga za kera zihuza umurongo n'ingingo, aho igikoresho kimwe cyakunze kuba hagati mu muyoboro w'amakuru - kandi iyo icyo gikoresho cyananiwe, buri gikoresho bitewe n'amakuru yacyo cyarazimye.
Mu by’ukuri, ba nyir’ubwato n’abubatsi bakoresha NMEA 2000 kugira ngo bashyire amakuru yo kugenda, ibipimo bya moteri, urwego rw’ibigega, ibipima ibidukikije, ndetse n’amakuru ya bateri ku mugongo umwe, agaragara ku imurikagurisha iryo ari ryo ryose rihuye n’iryo muri ubwo bwato.
NMEA 2000 vs NMEA 0183: Icyahindutse
Mbere ya NMEA 2000, ibikoresho by'ikoranabuhanga byo mu mazi byavugaga kuri NMEA 0183, protocole y'uruhererekane yashyizweho mu ntangiriro za 1980. NMEA 0183 iracyaboneka ku mato menshi, kandi gusobanukirwa itandukaniro ni byo bitanga impamvu inganda zakomeje gutera imbere.
NMEA 0183 ni porotokoli y'uruhererekane rw'amajwi. Igikoresho kimwe - "umuvugizi" - cyohereza interuro za ASCII ku 4.800 baud (ubwoko bwa 38.400-baud bwihuta bwongeweho nyuma, cyane cyane ku makuru akurikiranye imiyoboro ya AIS) ku "bumviriza" bumwe cyangwa bwinshi. Umuntu utega amatwi ashobora kwakira gusa umuvugizi umwe, bityo guhuza ibikoresho byinshi byasobanuraga multiplexers, buffers, na wiring diagrams byarushijeho kubabaza buri gikoresho cyongeweho.
NMEA 2000 yasimbuje ubwo buryo n'umuyoboro nyakuri:
| Ikiranga | NMEA 0183 | NMEA 2000 |
|---|---|---|
| Ubwubatsi | Umuntu uvuga ibintu kimwe gusa → abumva | Umuyoboro ukoresha amadosiye menshi, ibikoresho byose bivuga kandi bikumva |
| Icyiciro cy'umubiri | Uburyo bwo gusimbuza (uburyo bwa RS-422/RS-232) | bisi ya CAN, ipfundo ryijimye ryihariye |
| Umuvuduko | 4.800 baud (ubwoko bwa 38.400 bw'umuvuduko wo hejuru) | 250 kbit/s |
| Imiterere y'amakuru | Interuro z'inyandiko za ASCII (inyuguti ntarengwa 82) | Amakaramu magufi ya binary |
| Ibipimo ngenderwaho mpuzamahanga | IEC 61162-1 | IEC 61162-3 |
| Kongeramo igikoresho | Uburyo bushya bwo gukoresha insinga, birashoboka ko haba multiplexer | Shyira insinga ku ruti rw'umugongo |
| Imyitwarire yo gutsindwa | Kunanirwa kw'umuvuga byatesheje agaciro urunigi | Umuyoboro urakomeza nta node yananiwe |
Amabwiriza yombi ntabwo ahuye. Igikoresho cya NMEA 0183 ntigishobora guhuza umuyoboro wa NMEA 2000 mu buryo butaziguye; ibyuma bivanze bisaba igikoresho cy'irembo gihuza ibyo bibiri. Ku bwubatsi bishya n'ibivugururwa, NMEA 2000 ni yo mahitamo asanzwe - niyo mpamvu sisitemu za bateri zagenewe gukoreshwa mu mazi zirushaho gukenera kubivuga.
Uko Protocole Ikora: CAN Bus na PGN
Munsi y'ubuyobozi, NMEA 2000 yubatswe ku muyoboro w'ikoranabuhanga (CAN) — ikoranabuhanga rimwe rya bisi ryagaragaye mu myaka ibarirwa muri za mirongo mu buryo bw'imodoka n'inganda — rikora kuri 250 kbit/s. Icyo NMEA 2000 yongeraho hejuru ya CAN mbisi ni urwego rw'ikoreshwa rushingiye ku buryo busanzwe rugizweho ingaruka cyane na SAE J1939 (umuryango wa protocole y'itumanaho ikoreshwa mu makamyo n'imodoka ziremereye): amagambo asangiwe amenyesha buri gikoresho icyo byte biri ku nsinga bisobanura mu by'ukuri.
Iyo mvugo itunganijwe mu buryoImibare y'Amatsinda y'Ibipimo (PGNs)Buri PGN ni ubwoko bw'ubutumwa bwagenwe: PGN imwe ifite aho GPS iherereye, indi ifite RPM ya moteri, indi ifite ubujyakuzimu bw'amazi. Ubutumwa bugenda nk'amakaramu ya CAN hakoreshejwe indangamuntu ya biti 29 n'agace k'amakuru ya biti 8; ubutumwa bunini bugabanywamo amakaramu menshi bukongera bugateranywa n'iyakira. Kubera ko buri gikoresho cyemewe gisobanura PGN mu buryo bumwe, ecran ya Garmin ishobora gusoma amakuru ava kuri gateway ya moteri ya Yamaha na sensor y'ikigega cya gatatu nta n'umwe muri abo bakinnyi uhuza.
Ku bijyanye na sisitemu za bateri, itsinda ryihariye rya PGN rikora akazi karyo:
- PGN 127508 – Imiterere ya batiri: voltage, amashanyarazi, n'ubushyuhe kuri bateri
- PGN 127506 – Imiterere irambuye ya DC: imiterere y'akazi, ubuzima, n'igihe gisigaye
- PGN 127513 – Imiterere ya bateri: amakuru y'amashanyarazi, shimi, n'ubushobozi
Uburyo bwo gutanga integuza n'uburyo bwo gutanga integuza bigenda ukwabyo, binyuze mu butumwa bwemewe bw'umuyoboro (PGN 126983) — ni bwo ikibazo cya batiri kiba umuburo ugaragara kandi wumvikana ku buyobozi aho kuba ibendera rituje riri mu gasanduku.
Iyo sisitemu yo gucunga bateri (BMS) cyangwa irembo rya bateri byohereza izi PGN kuri network, ecran iyo ari yo yose iri kuri network ishobora kwerekana voltage ya pack, power draw, n'uko charge ihagaze - hatabayeho kongeramo ecran yihariye ya bateri kuri head. Buri bateri ihabwa inomero y'inyongera, ni ukuvuga uburyo network itandukanya banki y'inzu na bateri yo gutangira kandi ikayerekana ukwayo.
Uru rwego rwa PGN niho ikoranabuhanga rya bateri ya lithium rihurira n’ibikoresho by’ikoranabuhanga byo mu mazi, kandi niho imishinga yo guhuza ibintu igera cyangwa igahagarara. BMS ipima byose ariko ntiyohereze ikintu na kimwe ishyira amakuru nyayo ahantu nta muntu ushobora kuyabona; BMS ishyira mu bikorwa bateri ya PGN ihindura ayo makuru igice cy’ubwato.
Imiterere ya NMEA 2000 Network Architecture
Mu buryo bufatika, umuyoboro wa NMEA 2000 ukurikiza topology yoroshye kandi ikomeye - kandi gukomera ni ikintu kigaragara, kuko bituma imiyoboro imenyekana neza.
[ISHUSHO Y'UMWIMERERE HANO — imiterere y'umuyoboro yerekana umugongo, ibikoresho bihagarika umuriro, insinga zigwa, n'ibikoresho birimo MFD, gateway ya moteri, sensors, na bateri ya lithium ifite BMS. Inyandiko ikurikira: "Ishusho ya network ya NMEA 2000 ifite sisitemu ya bateri ihujwe binyuze kuri insinga zigwa"]
