Iindaba

Iprotocol ye-OCPP ibonelela ngesisombululo sonxibelelwano phakathi kwezikhululo zokutshajawallbox yombane itshaja yemoto kunye nayo nayiphi na inkqubo yolawulo oluphakathi. Ulwakhiwo lweprothokholi luxhasa uqhagamshelo lwayo nayiphi na intlawulowallbox yombane itshaja yemoto inkqubo yolawulo olungundoqo yomboneleli-nkonzo enazo zonke izithuba ezibizwayo.

I. Inkqubo ye-OCPP

1. Igama elipheleleyo le-OCPP yi-Open Charge Point Protocol, eyiprotocol yamahhala kunye nevulekileyo eyenziwe yi-OCA (i-Open Charge Alliance), umbutho osekelwe eNetherlands. Indawo yokuTyala evulekileyowallbox yombane itshaja yemoto Iprotocol (OCPP) isetyenziselwa unxibelelwano olumanyeneyo phakathi kwezikhululo zokutshaja (CS)wallbox yombane itshaja yemotokunye nayo nayiphi na inkqubo yolawulo lwesikhululo sokutshaja (CSMS). Ulwakhiwo lweprothokholi luxhasa uqhagamshelo lwe-CSMS yomboneleli wenkonzo yokutshaja nazo zonke izithuba zokutshaja. Izibonelelo zeprotocol ye-OCPP: ivulekile kwaye ikhululekile ukuyisebenzisa, inqanda ukutshixa kumboneleli omnye (iqonga lokutshaja), linciphisa ixesha lokudibanisa / umgudu kunye nemiba ye-IT.

2, Iinguqulelo eziphambili ze-OCPP protocol

OCPP1.2(ISEPHA) OCPP1.5(ISEPHA) OCPP1.6(ISEPHA/JSON)

OCPP2.0.1 (JSON)

I-SEPA inqunyelwe yimiqobo yayo yeprotocol, ayinakuba luluhlu olubanzi lokunyuswa ngokukhawuleza; Inguqulo ye-JSON yonxibelelwano lweWebSocket, ingaba kuyo nayiphi na indawo yenethiwekhi ukuthumela idatha komnye nomnye, iiprotokholi ezisetyenziswa kakhulu kwimarike yinguqulo ye-1.6J, i-OCPP2.0.1 yi-2018 ngaphandle kweprotocol ikhuthaza ukusetyenziswa kolwalathiso. kwixesha elizayo.

3, umahluko phakathi kweenguqulelo ezahlukeneyo ze-OCPPwallbox yombane imoto intlawulor

I-OCPP1.* iyahambelana neenguqulelo ezisezantsi, i-OCPP1.6 iyahambelana ne-OCPP1.5, i-OCPP1.5 iyahambelana ne-OCPP1.2.

I-OCPP2.0.1 ayihambelani ne-OCPP1.6, OCPP2.0.1 nangona eminye imixholo ye-OCPP1.6 nayo inakho, kodwa ifomathi yesakhelo sedatha ethunyelweyo yahluke ngokupheleleyo, i-OCPP2.0.1 yongeza okuninzi kwe-OCPP1.6. abanalo umsebenzi, umzekelo.

(1) I-StartTransaction kunye ne-StopTransaction kwi-OCPP1.6 ithathelwe indawo yi-TransactionEvent kwi-OCPP2.0.1.

(2) Uhlaziyo lweFirmware kwi-OCPP2.0.1 yongeza iisignesha zedijithali ukukhusela ukukhutshelwa kwe-firmware okungaphelelanga, okukhokelela ekungaphumeleli kohlaziyo lwe-firmware.

(3) I-transactionId iqinisekisiwe ukuba yodwa ngeqonga kwi-OCPP1.6, kwaye iqinisekisiwe ukuba yodwa ngesithuba sokutshajawallbox yombane itshaja yemotokwi-OCPP2.0.1.

(4) Kwi-OCPP1.6, iindawo eziphosakeleyo ziye zaphuculwa kwaye zaphuculwa, umzekelo: kwi-OCPP1.6, idatha ye-transactionId ngaphakathi kwe-StartTransaction inqunywe yiplatifomu, kodwa kwi-OCPP2.0.1, yimfumba yokuhlawulawallbox yombane itshaja yemoto emisela ixabiso letransactionId, enenzuzo kuba xa kukho ukusilela kumsebenzi womnatha, kuyimfuneko ukuthumela kwakhona idata yeStartTransaction xa imfumba yokutshaja.wallbox yombane itshaja yemoto kufuneka ithumele idatha kwakhona. Inzuzo yale nto kukuba xa kukho ukungaphumeleli kwenethiwekhi, kufuneka uphinde uthumele idatha ye-StartTransaction, ukuba i-OCPP1.6 inguqulo, iqonga linokuthi ligcine iikopi ezimbini zedatha yeTransaction efanayo, okukhokelela ekutsalweni kwedatha. imali yomthengi kabini;

(5) OCPP 2.0.1 iinkcukacha kunye neempawu kunenguqulo ye-1.6 eninzi kakhulu, ukuphuhliswa kobunzima kuye kwanda.

Okwesibini, isivumelwano se-OCPP 2.0.1

I-OCPP2.0.1 ixhasa ukusetyenziswa kwedatha ye-JSON yonxibelelwano lwee-websockets, i-OCPP2.0.1 ayihambelani ne-OCPP1.6.

Ixhasa iindlela ezininzi zogunyaziso lokhuseleko, i-ISO15118, ukutshaja ngobuchule, ulawulo lwesixhobo, ulawulo lokutshaja, njl njl.

OCPP Network Topology

1, OCPP2.0.1 Software Architecture

Ikakhulu ibandakanya iimodyuli zokuhanjiswa kwedatha, ukugunyazwa, ukhuseleko, ukucwangciswa, ukuxilongwa, ukulawulwa kwe-firmware, ulawulo lwesixhobo kunye nolawulo lokutshaja, njl.njl. Ulwahlulo lweemodyuli ezisebenzayo (inxalenye) kwi-OCPP2.0.1 protocol:

2, Ugqithiso lwedatha (DataTransfer) imodyuli

Sebenzisa ii-libwebsockets zethala leencwadi zomntu wesithathu ukuseka uqhagamshelwano lwe-websockets kunye ne-CSM ekude ngothungelwano lonxibelelwano lwedatha; sebenzisa ilayibrari yomntu wesithathu rapidjson ngenxa

3 、 Ugunyaziso (Ugunyaziso) Imodyuli

Iindlela zokugunyazisa ziquka i-RFID, iqhosha lokuqala, i-debit / credit card, ikhowudi ye-PIN, i-CSMS, i-idToken yendawo, i-ISO15118, isigunyaziso esingaxhunyiwe kwi-intanethi njalo njalo.

Umzekelo: Itshathi yoGunyaziso lweCSMS yoGunyaziso lweXesha

4, Ukhuseleko (Ukhuseleko) Imodyuli

Imodyuli yokhuseleko isebenzisa imodyuli yeqela lesithathu i-mbedtls RSA, i-ECC (i-Elliptic Curve) imodyuli ukubethela kunye nokucima idatha, kunye nemodyuli ye-X509 yokulawula izatifikethi.

Umzekelo: Idayagram yexesha lokuhlaziya izatifikethi zesikhululo sokutshaja

5, Iintengiselwano(Iintengiselwano) Imodyuli

Iintengiselwano zibhekisa kwinkqubo yokutshaja isithuthi sombane ngesixhobo sokutshaja.

Kwi-OCPP2.0, yonke imiyalezo enxulumene nentengiselwano idityaniswe kumyalezo , ethatha indawo , , , kunye neminye imiyalezo kwi-OCPP1.6.

Umzobo wexesha: Qalisa iNtengiselwano-Iplagi kunye nokuDlala

6. Imodyuli yeMeterValues

Ngexesha lenkqubo yokuthengiselana, kufuneka ithumele idatha yemitha yendawo kwi-CSMS ngamaxesha athile, ukwenzela ukuba i-CSMS kunye nabasebenzisi banokuqonda inkqubela phambili yentengiselwano ngexesha langempela.

Umzobo wexesha: idatha yemitha yentengiselwano

7, Iindleko zeModyuli

Imodyuli yokuhlawula yimodyuli entsha yesoftware kwi-OCPP2.0, esetyenziselwa ukubonelela ngexabiso kunye nolwazi lokuhlawula kubasebenzisi. Ibandakanya ikakhulu:

-Ngaphambi kokutshaja, ukubonelela ngolwazi oluneenkcukacha lwexabiso lesikhululo sokutshajawallbox yombane itshaja yemoto.

-Ngexesha lokutshaja, ukubonelela ngolwazi lweendleko zexesha langempela.

-Emva kokutshaja, ukubonelela ngolwazi lokugqibela lokutshaja.

(1) Umzobo wexesha lolwazi lwexabiso ngaphambi kokubiza:

(2) Itshathi yexesha lenkcazelo yokuhlawula ngexesha lokutshaja

(3) Umzobo wexesha lolwazi lokutshaja emva kokutshaja

8, Imodyuli yogcino

Ugcino ngumsebenzi ogciniweyo, onokumiselwa ngumsebenzisi. Kuba akukho zikhululo zokutshaja ezininziwallbox yombane itshaja yemoto kunye noluhlu lokuqhuba izithuthi zombane lilinganiselwe, abasebenzisi kufuneka baqinisekise ubunini bezixhobo zokutshaja kwangaphambili.

Umzobo wexesha lokugcinwa kwesixhobo sokutshaja esichongiweyo kwisikhululo sokutshajawallbox yombane itshaja yemoto:

9, Imodyuli yokuTshaja ngobuchule

Ukutshaja ngobuchule kubhekisa kukuziphatha kohlengahlengiso lwamandla okutshaja njengoko kufuneka ngexesha lenkqubo yokutshaja. Ibandakanya ikakhulu:

-Umthwalo wokulinganisa ngaphakathi kwisikhululo sokutshaja -Ulawulo lwenkqubo ephakathi

-Ukutshaja okuhlakaniphile kwendawo -Ulawulo lwenkqubo yolawulo lwamandla

Kwi-OCPP yokutshaja ngobuchulewallbox yombane itshaja yemoto ulawulo lubonakaliswa ikakhulu kwiiprofayili zokuTshaja, eziqulathe imida yokuhanjiswa kwamandla kwisikhululo sokutshaja kwindawo ethile ngexesha.

Ukutshaja isiqulatho somyalezo weprofayile (JSON):

10, Imodyuli yoxilongo

Isetyenziselwa ukuxilonga ukude iingxaki zesikhululo sokutshaja ngokufaka ifayile equlethe ulwazi lokuxilonga kwisikhululo sokutshaja.

Ifayile yoxilongo ifayile elayisha ngokulandelelana idayagramu:

Ikhowudi enxulumene nefayile yoxilongo (inxalenye):

11, Imodyuli yoLawulo lweFirmware

Xa isikhululo sokutshaja sifuna ukuhlaziya i-firmware, i-CSMS iya kwazisa isikhululo sokutshaja xa siqala ukukhuphela i-firmware entsha, kwaye isikhululo sokutshaja kufuneka sazise i-CSMS emva kwesinyathelo ngasinye sokukhuphela kunye nokufaka i-firmware entsha.

Umzekelo: Isazobe sexesha loHlaziyo lweFirmware (Inxalenye)

Ikhowudi enxulumene nohlaziyo lweFirmware (inxalenye):

12, imodyuli yoMyalezo

Imodyuli yokubonisa umyalezo isetyenziswa ngumqhubi wesikhululo sokutshaja (CSO) ukubonisa ulwazi olunxulumene nokutshaja kumsebenzisi, imodyuli yomyalezo wokubonisa ngumsebenzi omtsha kwi-OCPP 2.0, ingakumbi ibandakanya

-Seta umyalezo wokubonisa yiCSO

-Isiskhululo sokugcwalisawallbox yombane itshaja yemoto ilayisha umyalezo wokubonisa

Ukucwangcisa ixesha lomyalezo wedayagram:
