Iphrothokholi ye-OCPP inikeza isisombululo sokuxhumana esihlanganisiwe phakathi kweziteshi zokushajawallbox ishaja yemoto kagesi kanye nanoma yiluphi uhlelo lokuphatha olumaphakathi. Lesi sakhiwo sephrothokholi sisekela ukuxhumana kwanoma yikuphi ukushajawallbox ishaja yemoto kagesi uhlelo lokuphatha olumaphakathi lomhlinzeki wesevisi enazo zonke izikhala zokushaja.
I. Iphrothokholi ye-OCPP
1. Igama eligcwele le-OCPP yi-Open Charge Point Protocol, okuyiphrothokholi yamahhala nevulekile eyakhiwe yi-OCA (Open Charge Alliance), inhlangano ezinze e-Netherlands. I-Open Charge Pointwallbox ishaja yemoto kagesi I-Protocol (OCPP) isetshenziselwa ukuxhumana okuhlangene phakathi kweziteshi zokushaja (CS)wallbox ishaja yemoto kagesikanye nanoma yiluphi uhlelo lokuphatha isiteshi sokushaja (CSMS). Lesi sakhiwo somthethonqubo sisekela ukuxhumana kwanoma iyiphi i-CSMS yomhlinzeki wesevisi eshajayo nakho konke okuthunyelwe kokushaja. Izinzuzo zephrothokholi ye-OCPP: ivuliwe futhi ikhululekile ukusetshenziswa, ivimbela ukukhiya kumhlinzeki oyedwa (inkundla yokushaja), inciphisa isikhathi/umzamo wokuhlanganisa kanye nezinkinga ze-IT.
2, Izinguqulo eziyinhloko zephrothokholi ye-OCPP
OCPP1.2(SOAP) OCPP1.5(SOAP) OCPP1.6(SOAP/JSON)
I-OCPP2.0.1 (JSON)
I-SOAP inqunyelwe izithiyo zayo zephrothokholi, ayikwazi ukuba yinhlobonhlobo yokuphromotha okusheshayo; Inguqulo ye-JSON yokuxhumana kwe-WebSocket, ingaba kunoma iyiphi indawo yenethiwekhi ukuze ithumelelane idatha, izivumelwano ezisetshenziswa kakhulu emakethe inguqulo ye-1.6J, i-OCPP2.0.1 ingu-2018 ngaphandle kwephrothokholi iphromotha ukusetshenziswa kwesikhombisi-ndlela. yekusasa.
3, umehluko phakathi kwezinguqulo ezihlukahlukene ze-OCPPwallbox electric car charger
I-OCPP1.* ihambisana nezinguqulo eziphansi, i-OCPP1.6 ihambisana ne-OCPP1.5, i-OCPP1.5 ihambisana ne-OCPP1.2.
I-OCPP2.0.1 ayihambelani ne-OCPP1.6, OCPP2.0.1 nakuba okunye okuqukethwe kwe-OCPP1.6 nakho kunakho, kodwa ifomethi yozimele wedatha ethunyelwe ihluke ngokuphelele, i-OCPP2.0.1 yengeze okuningi kwe-OCPP1.6 awunawo umsebenzi, isibonelo.
(1) I-StartTransaction ne-StopTransaction ku-OCPP1.6 ithathelwa indawo TransactionEvent ku-OCPP2.0.1.
(2) Isibuyekezo se-Firmware ku-OCPP2.0.1 sengeza amasiginesha edijithali ukuvimbela ukulandwa kwe-firmware okungaphelele, okuholela ekuhlulekeni kokubuyekezwa kwe-firmware.
(3) I-Id ye-transaction iqinisekisiwe ukuthi izohluka ngeplathifomu eku-OCPP1.6, futhi iqinisekiswa ukuthi izohluka ngeposi lokushaja.wallbox ishaja yemoto kagesiku-OCPP2.0.1.
(4) Ku-OCPP1.6, izindawo ezinokukhubazeka zithuthukisiwe futhi zathuthukiswa, isibonelo: ku-OCPP1.6, idatha ye-transactionId ngaphakathi kwe-StartTransaction inqunywa iplathifomu, kodwa ku-OCPP2.0.1, iyinqwaba yokushaja.wallbox ishaja yemoto kagesi enquma inani le-transactionId, okuyinzuzo ngoba uma kukhona ukwehluleka kwenethiwekhi, kuyadingeka ukuthi uphinde uthumele idatha ye-StartTransaction uma inqwaba yokushaja.wallbox ishaja yemoto kagesi kufanele ithumele idatha futhi. Inzuzo yalokhu ukuthi uma kukhona ukwehluleka kwenethiwekhi, udinga ukuthumela kabusha idatha ye-StartTransaction, uma kuyinguqulo ye-OCPP1.6, isiteji kungenzeka ukuthi silondoloze amakhophi amabili wedatha efanayo ye-Transaction, okuholela ekudonsweni kwedatha. imali yekhasimende kabili;
(5) Imininingwane ye-OCPP 2.0.1 nezici kunenguqulo engu-1.6 yokuningi, ukuthuthukiswa kobunzima kunyukile.
Okwesibili, isivumelwano se-OCPP 2.0.1
I-OCPP2.0.1 isekela ukusetshenziswa kwedatha yefomethi ye-JSON ukuxhumana nama-websockets, i-OCPP2.0.1 ayihambelani ne-OCPP1.6.
Isekela izindlela eziningi zokugunyazwa kokuphepha, i-ISO15118, ukushaja okuhlakaniphile, ukuphathwa kwedivayisi, ukuphathwa kokushaja, njll. Ifaka ukuhambisana okuphezulu, ukuvikeleka okuphezulu kanye nokukaleka okuphezulu.
I-OCPP Network Topology
