Iphrothokholi ye-OCPP inikeza ikhambi lokuxhumana elihlangene phakathi kweziteshi zokushajaishaja yemoto kagesi yebhokisi lodonga kanye nanoma yiluphi uhlelo lokuphatha oluphakathi. Lolu hlaka lwephrothokholi lusekela ukuxhumana kwanoma yikuphi ukushajaishaja yemoto kagesi yebhokisi lodonga uhlelo lokuphatha oluphakathi lomhlinzeki wesevisi olunazo zonke izikhala zokushaja.
I. Iphrothokholi ye-OCPP
1. Igama eliphelele le-OCPP yi-Open Charge Point Protocol, okuyiphrothokholi yamahhala nevulekile eyakhiwe yi-OCA (Open Charge Alliance), inhlangano eseNetherlands.ishaja yemoto kagesi yebhokisi lodonga Iphrothokholi (OCPP) isetshenziselwa ukuxhumana okuhlangene phakathi kweziteshi zokushaja (CS)ishaja yemoto kagesi yebhokisi lodongakanye nanoma yiluphi uhlelo lokuphatha isiteshi sokushaja (i-CSMS). Lolu hlobo lwephrothokholi lusekela ukuxhumana kwe-CSMS yanoma yimuphi umhlinzeki wesevisi yokushaja nazo zonke izikhala zokushaja. Izinzuzo zephrothokholi ye-OCPP: ivulekile futhi imahhala ukuyisebenzisa, ivimbela ukukhiya kumhlinzeki oyedwa (ipulatifomu yokushaja), kunciphisa isikhathi/umzamo wokuhlanganisa kanye nezinkinga ze-IT.
2. Izinguqulo eziyinhloko zephrothokholi ye-OCPP
OCPP1.2(INTSAPHO) OCPP1.5(INTSAPHO) OCPP1.6(INTSAPHO/JSON)
I-OCPP2.0.1 (i-JSON)
I-SOAP inqunyelwe yimikhawulo yayo yephrothokholi, ayikwazi ukuba nohlu olubanzi lokukhushulwa okusheshayo; inguqulo ye-JSON yokuxhumana kwe-WebSocket, ingaba kunoma iyiphi indawo yenethiwekhi ukuthumela idatha komunye nomunye, amaphrothokholi asetshenziswa kakhulu emakethe inguqulo ye-1.6J, i-OCPP2.0.1 ingu-2018 ophuma kuphrothokholi ekhuthaza ukusetshenziswa kwesiqondiso sesikhathi esizayo.
3, umehluko phakathi kwezinguqulo ezahlukene ze-OCPPishaja yemoto kagesi yebhokisi lodongar
I-OCPP1.* iyahambisana nezinguqulo eziphansi, i-OCPP1.6 iyahambisana ne-OCPP1.5, i-OCPP1.5 iyahambisana ne-OCPP1.2.
I-OCPP2.0.1 ayihambisani ne-OCPP1.6, i-OCPP2.0.1 yize okunye okuqukethwe yi-OCPP1.6 nakho kunakho, kodwa ifomethi yohlaka lwedatha oluthunyelwe ibihluke ngokuphelele, i-OCPP2.0.1 engeziwe i-OCPP1.6 eningi ayinawo umsebenzi, isibonelo.
(1) I-StartTransaction kanye ne-StopTransaction ku-OCPP1.6 zithathelwa indawo yi-TransactionEvent ku-OCPP2.0.1.
(2) Isibuyekezo se-Firmware ku-OCPP2.0.1 sengeza amasignesha edijithali ukuvimbela ukulandwa kwe-firmware okungaphelele, okuholela ekuhlulekeni kokubuyekezwa kwe-firmware.
(3) I-transactionId iqinisekisiwe ukuthi ihlukile yipulatifomu ku-OCPP1.6, futhi iqinisekisiwe ukuthi ihlukile yiposi yokushaja.ishaja yemoto kagesi yebhokisi lodongaku-OCPP2.0.1.
(4) Ku-OCPP1.6, izindawo ezinephutha zilungiselelwe futhi zathuthukiswa, isibonelo: ku-OCPP1.6, idatha ye-transactionId ngaphakathi kwe-StartTransaction inqunywa yipulatifomu, kodwa ku-OCPP2.0.1, iyinqwaba yokushaja.ishaja yemoto kagesi yebhokisi lodonga lokho kunquma inani le-transactionId, okuyinto enhle ngoba uma kukhona ukwehluleka kwenethiwekhi, kuyadingeka ukuthumela kabusha idatha ye-StartTransaction lapho inqwaba yokushaja ishaja.ishaja yemoto kagesi yebhokisi lodonga kufanele athumele idatha futhi. Inzuzo yalokhu ukuthi uma kukhona ukwehluleka kwenethiwekhi, kudingeka ukuthi kuthunyelwe kabusha idatha ye-StartTransaction, uma kuyinguqulo ye-OCPP1.6, ipulatifomu cishe izogcina amakhophi amabili edatha efanayo ye-Transaction, okuholela ekukhishweni kwemali yekhasimende kabili;
(5) Imininingwane nezici ze-OCPP 2.0.1 kunenguqulo engu-1.6, ukuthuthukiswa kobunzima kukhuphukile.
Okwesibili, isivumelwano se-OCPP 2.0.1
I-OCPP2.0.1 isekela ukusetshenziswa kokuxhumana kwe-websockets yefomethi ye-JSON, i-OCPP2.0.1 ayihambisani ne-OCPP1.6.
Isekela izindlela eziningi zokugunyazwa kokuphepha, i-ISO15118, ukushaja okuhlakaniphile, ukuphathwa kwedivayisi, ukuphathwa kokushaja, njll. Ifaka ukuhambisana okuphezulu, ukuphepha okuphezulu kanye nokukhula okuphezulu.
I-Topology Yenethiwekhi ye-OCPP
1、OCPP2.0.1 Ukwakhiwa Kwesofthiwe
Ihlanganisa ikakhulukazi amamojula okudluliswa kwedatha, ukugunyazwa, ukuphepha, ukucushwa, ukuxilongwa, ukuphathwa kwe-firmware, ukuphathwa kwedivayisi kanye nokuphathwa kokushaja, njll. Ukuhlukaniswa kwemojula okusebenzayo (ingxenye) kuphrothokholi ye-OCPP2.0.1:
2, Ukudluliswa kwedatha (DataTransfer) module
Sebenzisa i-libwebsockets yomtapo wolwazi wesithathu ukuze usungule uxhumano lwe-websockets ne-CSMS ekude ngenethiwekhi ukuze kusetshenziswe idatha; sebenzisa i-library rapidjson yomtapo wolwazi wesithathu ukuze
3, Imodyuli Yokugunyazwa (Yokugunyazwa)
Izindlela zokugunyaza zifaka phakathi i-RFID, inkinobho yokuqalisa, ikhadi ledebithi/lesikweletu, ikhodi ye-PIN, i-CSMS, i-idToken yendawo, i-ISO15118, ukugunyazwa okungaxhunyiwe ku-inthanethi nokunye.
Isibonelo: Ishadi Lesikhathi Sokugunyazwa kwe-CSMS
4, Imojuli Yokuphepha (Yokuphepha)
Imojuli yokuphepha isebenzisa imojuli yelabhulali yenkampani yangaphandle i-mbedtls RSA, imojuli ye-ECC (Elliptic Curve) ukubethela nokuqaqa idatha, kanye nemojuli ye-X509 ukuphatha izitifiketi.
Isibonelo: Idayagramu yesikhathi yokubuyekeza izitifiketi zesiteshi sokushaja
5, Imodyuli Yokuthengiselana (Yokuthengiselana)
Ukuthengiselana kubhekisela enqubweni yokushaja imoto kagesi ngedivayisi yokushaja.
Ku-OCPP2.0, yonke imiyalezo ehlobene nokuthengiselana ihlanganiswe kumlayezo
Umdwebo Wesikhathi: Qala Ukuthengiselana - Xhuma bese Udlala
6, imodyuli yeMeterValues
Ngesikhathi senqubo yokuthengiselana, idinga ukuthumela idatha yamamitha endawo ku-CSMS ngezikhathi ezithile, ukuze i-CSMS kanye nabasebenzisi bakwazi ukuqonda inqubekela phambili yokuthengiselana ngesikhathi sangempela.

8, Imodyuli Yokubhuka
Ukubhukha kuwumsebenzi ogciniwe, ongasethwa yi-opharetha. Njengoba zingekho iziteshi eziningi zokushajaishaja yemoto kagesi yebhokisi lodonga futhi ububanzi bokushayela kwezimoto zikagesi bulinganiselwe, abasebenzisi badinga ukuqinisekisa ubunikazi bemishini yokushaja kusenesikhathi.
Idayagramu yesikhathi yokubhuka imishini yokushaja eqokiwe esiteshini sokushajaishaja yemoto kagesi yebhokisi lodonga:
9, Imojuli Yokushaja Ehlakaniphile
Ukushaja okuhlakaniphile kubhekisela ekuziphatheni kokulungisa amandla okushaja ngokuguquguqukayo njengoba kudingeka ngesikhathi senqubo yokushaja. Kuhlanganisa ikakhulukazi:
-Ukulinganisela umthwalo ngaphakathi kwesiteshi sokushaja -Ukulawula uhlelo oluphakathi
-Ukushaja okuhlakaniphile kwendawo -Ukulawula uhlelo lokuphatha amandla
Ukushaja okuhlakaniphile kwe-OCPPishaja yemoto kagesi yebhokisi lodonga Ukulawula kubonakala kakhulu kumaphrofayili Okushaja, aqukethe imikhawulo yokudlulisa amandla esiteshini sokushaja ngesikhathi esithile.
Okuqukethwe komlayezo wamaphrofayela okushaja (i-JSON):
10, Imodyuli Yokuxilonga
Isetshenziselwa ukuxilonga izinkinga zesiteshi sokushaja ukude ngokulayisha ifayela eliqukethe ulwazi lokuxilonga oluvela esiteshini sokushaja.
Umdwebo wokulandelana kokulayisha ifayela lolwazi lokuxilonga:
Ikhodi ehlobene nefayela lokuxilonga (ingxenye):
11, Imodyuli Yokuphathwa Kwe-Firmware
Uma isiteshi sokushaja sidinga ukuvuselela i-firmware, i-CSMS izokwazisa isiteshi sokushaja uma isingaqala ukulanda i-firmware entsha, futhi isiteshi sokushaja kufanele sazise i-CSMS ngemva kwesinyathelo ngasinye sokulanda nokufaka i-firmware entsha.
