Iindaba

Iprotokholi ye-OCPP ibonelela ngesisombululo sonxibelelwano esidibeneyo phakathi kwezikhululo zokutshajaitshaja yemoto yombane yebhokisi yodonga kunye nayo nayiphi na inkqubo yolawulo oluphambili. Olu lwakhiwo lweprotocol luxhasa uqhagamshelo lwalo naluphi na utshajaitshaja yemoto yombane yebhokisi yodonga Inkqubo yolawulo oluphambili yomboneleli weenkonzo enazo zonke izithuba zokutshaja.

I. Iprotokholi ye-OCPP

1. Igama elipheleleyo le-OCPP yi-Open Charge Point Protocol, eyi-protocol yasimahla nevulekileyo eyenziwe yi-OCA (Open Charge Alliance), umbutho oseNetherlands.itshaja yemoto yombane yebhokisi yodonga Iprotokholi (OCPP) isetyenziselwa unxibelelwano oludibeneyo phakathi kwezikhululo zokutshaja (CS)itshaja yemoto yombane yebhokisi yodongakunye nayo nayiphi na inkqubo yolawulo lwesitishi sokutshaja (i-CSMS). Olu lwakhiwo lweprotocol luxhasa ukunxibelelana kwe-CSMS yomboneleli weenkonzo zokutshaja nazo zonke izithuba zokutshaja. Iingenelo zeprotocol ye-OCPP: ivulekile kwaye isimahla ukuyisebenzisa, ithintela ukutshixeka kumboneleli omnye (iqonga lokutshaja), inciphisa ixesha/umgudu wokudibanisa kunye nemiba ye-IT.

2. Iinguqulelo eziphambili zeprotocol ye-OCPP

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

I-OCPP2.0.1 (i-JSON)

I-SOAP ithintelwe yimida yayo yeprotocol, ayinakuba noluhlu olubanzi lokukhuthaza ngokukhawuleza; inguqulelo ye-JSON yonxibelelwano lweWebSocket, ingaba kuyo nayiphi na indawo yenethiwekhi ukuthumela idatha komnye nomnye, iiprotocol ezisetyenziswa kakhulu kwimarike yinguqulelo ye-1.6J, i-OCPP2.0.1 yiprotocol ka-2018 ephumileyo ikhuthaza ukusetyenziswa kwesikhokelo sekamva.

3, umahluko phakathi kweenguqulelo ezahlukeneyo ze-OCPPitshaja yemoto yombane yebhokisi yodongar

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, i-OCPP2.0.1 nangona ezinye zezinto ezikwi-OCPP1.6 nazo zinjalo, kodwa ifomathi yesakhelo sedatha esithunyelweyo yahlukile ngokupheleleyo, i-OCPP2.0.1 yongeze uninzi lwe-OCPP1.6 ayinawo umsebenzi, umzekelo.

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

(2) Uhlaziyo lweFirmware kwi-OCPP2.0.1 longeza iimpawu zedijithali ukuthintela ukhuphelo lwe-firmware olungaphelelanga, nto leyo ekhokelela ekusileleni kohlaziyo lwe-firmware.

(3) I-transactionId iqinisekisiwe ukuba iyingqayizivele yiqonga elikwi-OCPP1.6, kwaye iqinisekisiwe ukuba iyingqayizivele yiposi yokutshaja.itshaja yemoto yombane yebhokisi yodongakwi-OCPP2.0.1.

(4) Kwi-OCPP1.6, iindawo ezineziphene zilungisiwe kwaye ziphuculwe, umzekelo: kwi-OCPP1.6, idatha ye-transactionId ngaphakathi kwi-StartTransaction imiselwa yiplatifomu, kodwa kwi-OCPP2.0.1, yinqwaba yokutshaja.itshaja yemoto yombane yebhokisi yodonga emisela ixabiso le-transactionId, nto leyo eluncedo kuba xa kukho ukusilela kwenethiwekhi, kuyimfuneko ukuthumela kwakhona idatha ye-StartTransaction xa inqwaba yokutshajaitshaja yemoto yombane yebhokisi yodonga kufuneka athumele idatha kwakhona. Inzuzo yoku kukuba xa kukho ukusilela kwenethiwekhi, kufuneka kuthunyelwe kwakhona idatha yeStartTransaction, ukuba yinguqulelo ye-OCPP1.6, iqonga linokugcina iikopi ezimbini zedatha yeTransaction efanayo, nto leyo ekhokelela ekutsalweni kwemali yomthengi kabini;

(5) Iinkcukacha kunye neempawu ze-OCPP 2.0.1 kunenguqulelo ye-1.6, uphuhliso lobunzima lunyukile.

Okwesibini, isivumelwano se-OCPP 2.0.1

I-OCPP2.0.1 ixhasa ukusetyenziswa konxibelelwano lwedatha ye-JSON format data websockets, i-OCPP2.0.1 ayihambelani ne-OCPP1.6.

Ixhasa iindlela ezininzi zokuqinisekisa ukhuseleko, i-ISO15118, ukutshaja ngobuchule, ulawulo lwesixhobo, ulawulo lokutshaja, njl. Ihambelana kakhulu, ukhuseleko oluphezulu kunye nokukhula okuphezulu.

I-Topology yeNethiwekhi ye-OCPP
