Unxibelelwano lwe-BMS lokudibanisa ugcino lwelanga: Ukuhambelana kwe-CAN, i-RS485, kunye ne-Inverter Protocol

Kutheni uNxibelelwano lwe-Inverter luyiNqanaba lokuSilela kweNdawo yokuGcina iiSolar

Thetha nabani na oye wayalela ukuba kugcinwe amandla elanga ngesikali kwaye uya kuva inguqulelo yebali elifanayo: ipakethi iphumelele uvavanyo ngalunye ebhentshini. Ii-voltage zeseli ngaphakathi kwe-spec, zilungelelanisa ukusebenza, ukhuseleko luvutha njengoko bekulindelwe. Emva koko kwindawo, i-inverter kunye nebhetri zala ukuthetha omnye komnye - okanye okubi nangakumbi, zathetha, kodwa zaxela imeko engalunganga yetshaja, zala imiyalelo yetshaja, okanye zaphosa iikhowudi zempazamo akukho mntu wayenokukwazi ukuzichaza. Ipakethi yabuya ekhaya. Iprojekthi ilahlekelwe yiveki.

Le ayisiyonto ingaqhelekanga. Yenye yezona ngxaki zixhaphakileyo kwiiprojekthi zokugcina amandla elanga, kwaye phantse ngalo lonke ixesha unobangela uyafana: i-BMS enechweba le-CAN, kodwa ayithethi ngenkqubo elindelwe yi-inverter. Ngokukodwa kwindawo yokugcina, unxibelelwano aluyonto ibalulekileyo - sisiseko inkqubo emi kuso.

Iitshaneli Ezintathu — Oko Ngamnye Wenzayo Ngokwenene Kwinkqubo Yokugcina

Unxibelelwano lwe-BMS olugcina amandla elanga ludla ngokusebenzisa imijelo emithathu ebonakalayo, nganye iphethe ipatheni eyahlukileyo yendlela. Ukwazi ukuba yeyiphi imijelo elawula inyathelo lokuqala lokubhala iinkcukacha zonxibelelwano eziluncedo:

Ibhasi ye-CAN

Ikhonkco eliphambili ngexesha langempela phakathi kwebhetri kunye ne-inverter. I-CAN ithwala imida yangoku yokutshaja, imida yangoku yokutshaja kunye nokukhupha, imida ye-voltage, iiflegi zempazamo, kunye nemiyalezo yokulawula ethile yeprotocol. Le yitshaneli i-inverter exhomekeke kuyo ukuze ikwazi ukutshaja kunye nokukhupha ibhetri ngokukhuselekileyo. Ukuba i-CAN ayiphumeleli okanye ithetha iprotocol engalunganga, yonke inkqubo ayinanto ingasetyenziswayo.

I-RS485

Isetyenziselwa ukujonga ngesantya esicothayo, i-telemetry, kunye nokudibanisa neenkqubo zolawulo lwamandla ezikwinqanaba lesiza okanye isoftware ye-upper-monitor. I-RS485 ikwayindlela eqhelekileyo yokujonga iinkqubo zeepakethi ezininzi ezinamathele kwi-daisy apho ipakethi nganye inika ingxelo kumlawuli. I-Modbus RTU yiprotokholi eqhelekileyo kweli khonkco.

ibluetooth

Kwi-installer kunye ne-end-user diagnostics — i-app ye-smartphone ebonisa i-voltages yeseli, amaqondo obushushu, imeko yokulinganisela, kunye nembali ye-alamu. Ayiyonxalenye ye-live control loop; iluncedo ekuqaliseni, ekusombululeni iingxaki, nasekucaciseni umsebenzisi.

Umahluko Obalulekileyo: Ukuba ne-CAN akuthethi Ukuthetha iProtokholi Yakho ye-Inverter

Eli candelo lifanelekile ukucothisa isantya, kuba kulapho uninzi lokuthenga iphepha leenkcazo lungahambi kakuhle khona. Ibhasi ye-CAN ngumgangatho oqhelekileyo nowombane — indlela yokuhambisa iibhithi phakathi kwezixhobo ngokuthembekileyo. Ayisiyo protocol. Iiprotokholi zizivumelwano malunga nokuba ezo bithi zithetha ukuthini: yeyiphi i-ID yomyalezo ephethe imeko yetshaja, yeyiphi i-byte layout emele umda wangoku wetshaja, zeziphi iikhowudi zempazamo ezichazweyo.

Iiyunithi ezimbini ze-BMS zinokuxhasa i-CAN kwaye zingakwazi ukuthetha ne-inverter enye, kuba zisebenzisa iiprotokholi ezahlukeneyo. I-BMS exhasa ujongano lwe-CAN oluqhelekileyo kodwa ingasebenzisi ulwakhiwo lomyalezo olulindelwe yi-inverter yakho iya kuvelisa kanye ukusilela kwindawo echazwe apha ngasentla: iingcingo ziqhagamshelwe, izibane zivuliwe, kwaye akukho nto iluncedo etshintshiswayo.

IiProtokholi ze-Common Storage Inverter, kunye noko kuthethwa yiNkxaso yeNative

Kwihlabathi liphela, indawo yokugcina izinto zokuhlala kunye neendawo ezincinci zorhwebo zidibene kwiseti encinci yeenkqubo ze-inverter. Uluhlu oluchanekileyo olufunekayo yiprojekthi luxhomekeke ekubeni yeyiphi i-inverter echaziweyo, kodwa incoko idla ngokubandakanya iimpawu eziphambili ezikhonza imarike nganye yengingqi. Ngaphantsi kwenqanaba lebhrendi, kukho ubunzulu obubini bokuhambelana ekufuneka buqondwe:

Inkxaso yeprotocol yendalo

I-firmware ye-BMS isebenzisa i-protocol ye-inverter ngokuthe ngqo. Kwiimeko ezininzi, ukugunyazisa kuba lula kakhulu kuba i-protocol sele isetyenziswa kwinqanaba le-firmware — nangona iinkcukacha ezifana ne-protocol version, i-firmware version kumacala omabini, i-parameter mapping, kunye noqwalaselo lwe-inverter side kusafuneka kuqinisekiswe ukuba iza kusetyenziswa ngokuchanekileyo. Oku kukunciphisa ukusilela kwentsimi xa kuthelekiswa nendlela enokucwangciswa okanye ye-CAN kuphela, apho umaleko we-protocol ngokwawo kufuneka uphuhliswe okanye uhlengahlengiswe ukongeza kuzo zonke ezi zinto zingasentla.

Inkxaso elungisekayo/eguquguqukayo

I-BMS ibonelela nge-CAN kunye ne-upper-monitor configuration interface evumela ukuba iprotocol ikhethwe okanye ihlengahlengiswe kwi-inverter ethile. Oku kuguquguquka ngakumbi kodwa kufuna ukuba umfaki okanye umthengisi azi ukuba benza ntoni ngexesha lokuqalisa.

Ujongano lweCAN kuphela

I-BMS inechweba le-CAN kodwa ayisebenzisi iprotocol ye-inverter. I-integrator kulindeleke ukuba iphuhlise umaleko weprotocol ngokwayo. Kwiiprojekthi ezininzi zokugcina oku akunakwenzeka ngokwezorhwebo — ixesha lobunjineli libiza ngaphezu kokukhetha i-BMS enenkxaso yendalo.

Umbuzo osebenzayo onyanisekileyo kuyo nayiphi na i-RFQ yokugcina: ngaba ufuna i-native, i-configurable, okanye uza kwakha umaleko weprotocol? Uninzi lwabafaki bafuna i-native. Abavelisi beepakethi abaqhuba iiprojekthi ezininzi kwiimveliso ezahlukeneyo ze-inverter badla ngokufuna i-configurable.

Indlela Yokuqinisekisa Ukuhambelana Ngaphambi Kokuba U-odole

Olu luluhlu lokuhlola lwangaphambi kwe-RFQ oluthintela ukusilela kwindawo echazwe ekuqaleni. Ukusebenza ngalo kuthatha ngaphantsi kweyure, kwaye konga iiveki emva komlambo:

• Qinisekisa imodeli yakho ye-inverter kuqala, hayi i-BMS.I-inverter idla ngokuba nolindelo oluqinileyo lweprotocol kune-BMS. Tshixa i-inverter, uze uqinisekise ukuba i-BMS iyahambelana nayo — hayi ngenye indlela.
• Cela umthengisi we-BMS uluhlu lweeprotocol ze-inverter ezisetyenziswa ngokwendalo kwinqanaba le-firmware, ngegama.Uluhlu lokwenyani luya kuchaza iiprotokholi ezithile. Impendulo engacacanga ethi "ixhasa zonke ii-inverters ezinkulu" yimpawu ebalulekileyo ekufuneka ithathwe nzulu.
• Cela uxwebhu lweprotocol okanye ingxelo yokuqinisekisa ukuhambelana ethile kwimodeli yakho ye-inverter.Umthengisi onyanisekileyo uya kuqinisekisa ukuba oku kuyafana okanye athembeke ukuba umsebenzi wohlengahlengiso uyafuneka.
• Ukuba uphawu lwe-inverter lulolwengingqi okanye lusandula ukukhutshwa,kulindeleke ukuba kufuneke inkxaso enokulungiselelwa endaweni yenkxaso yendalo, kunye nexesha lokulungiselela uhlahlo-lwabiwo mali ngokufanelekileyo.
• Kwiiprojekthi ze-multi-inverter (umz. umenzi wepakethi obonelela ngeempawu ezahlukeneyo ze-inverter),khetha i-BMS enenkxaso ye-upper-monitor enokulungiselelwa kune-BMS egcina iprotokholi enye efektri.
