Amakuru

Porotokole ya OCPP itanga igisubizo cy'itumanaho rihuriweho hagati y'aho gushyurirachargeur y'imodoka ikoresha amashanyarazi ku rukuta na sisitemu iyo ari yo yose yo gucunga. Iyi miterere ya protocole ishyigikira guhuza kwa charger iyo ari yo yosechargeur y'imodoka ikoresha amashanyarazi ku rukuta sisitemu yo gucunga y'ikigo cy'abatanga serivisi hamwe n'ibice byose byo kwishyuza.

I. Porotokole ya OCPP

1. Izina ryuzuye rya OCPP ni Open Charge Point Protocol, ikaba ari protocole y'ubuntu kandi ifunguye yakozwe na OCA (Open Charge Alliance), umuryango ufite icyicaro mu Buholandi.chargeur y'imodoka ikoresha amashanyarazi ku rukuta Porotokole (OCPP) ikoreshwa mu gutumanaho hagati y’ibiro bishinzwe gusharija (CS)chargeur y'imodoka ikoresha amashanyarazi ku rukutana sisitemu iyo ari yo yose yo gucunga sitasiyo zo gusharija (CSMS). Iyi miterere ya protocole ishyigikira guhuza CSMS y'umutanga serivisi zo gusharija n'ibice byose byo gusharija. Ibyiza bya protocole ya OCPP: ifunguye kandi ikoreshwa ku buntu, irinda ko umutanga serivisi umwe (urubuga rwo gusharija), igabanya igihe/imbaraga zo guhuza n'ibibazo by'ikoranabuhanga.

2. Verisiyo z'ingenzi za protocole ya OCPP

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

OCPP2.0.1 (JSON)

SOAP igengwa n’amabwiriza yayo ya protocole, ntabwo ishobora kuba ahantu henshi ho kwamamaza vuba; verisiyo ya JSON ya WebSocket communication, ishobora kuba mu buryo ubwo aribwo bwose bwo koherezanya amakuru, protocole zikoreshwa cyane ku isoko ni verisiyo ya 1.6J, OCPP2.0.1 niyo protocole yo mu 2018 irimo guteza imbere ikoreshwa ry’icyerekezo cy’ejo hazaza.

3, itandukaniro riri hagati ya verisiyo zitandukanye za OCPPumuriro w'imodoka ikoresha amashanyarazi ku rukutar

OCPP1.* ijyanye na verisiyo zo hasi, OCPP1.6 ijyanye na OCPP1.5, OCPP1.5 ijyanye na OCPP1.2.

OCPP2.0.1 ntabwo ijyanye na OCPP1.6, OCPP2.0.1 nubwo bimwe mu bikubiye muri OCPP1.6 nabyo bifitanye isano, ariko imiterere y'amakuru yoherejwe yari itandukanye rwose, OCPP2.0.1 yongewemo byinshi OCPP1.6 ntabwo ifite imikorere, urugero.

(1) StartTransaction na StopTransaction muri OCPP1.6 byasimbuwe na TransactionEvent muri OCPP2.0.1.

(2) Ivugurura rya firmware muri OCPP2.0.1 ryongeraho umukono wa digitale kugira ngo hirindwe ko firmware idakora neza, bigatuma habaho kunanirwa gukosora firmware.

(3) TransactionId yizewe ko izaba yihariye na platform muri OCPP1.6, kandi yizewe ko izaba yihariye na charger postchargeur y'imodoka ikoresha amashanyarazi ku rukutamuri OCPP2.0.1.

(4) Muri OCPP1.6, ahantu hafite inenge haranogejwe kandi havuguruwe, urugero: muri OCPP1.6, amakuru ya transactionId ari muri StartTransaction agenwa na platform, ariko muri OCPP2.0.1, ni charger pile.chargeur y'imodoka ikoresha amashanyarazi ku rukuta ibyo bigena agaciro ka transactionId, ibyo bikaba ari byiza kuko iyo hari ikibazo cy'umuyoboro, ni ngombwa kongera kohereza amakuru ya StartTransaction igihe umurundo wo gusharijachargeur y'imodoka ikoresha amashanyarazi ku rukuta agomba kongera kohereza amakuru. Akamaro k'ibi ni uko iyo habayeho ikibazo cy'umuyoboro w'itumanaho, ugomba kongera kohereza amakuru ya StartTransaction, niba ari verisiyo ya OCPP1.6, urubuga rushobora kubika kopi ebyiri z'amakuru amwe ya Transaction, bigatuma amafaranga y'umukiriya akurwa inshuro ebyiri;

(5) Ibisobanuro birambuye n'imikorere ya OCPP 2.0.1 kurusha verisiyo ya 1.6, iterambere ry'ingorane ryariyongereye.

Icya kabiri, amasezerano ya OCPP 2.0.1

OCPP2.0.1 ishyigikira ikoreshwa ry'itumanaho rya JSON format data websockets, OCPP2.0.1 ntabwo ijyanye na OCPP1.6.

Ishyigikira uburyo bwinshi bwo kwemeza umutekano, ISO15118, gusharija mu buryo bwihuse, gucunga ibikoresho, gucunga gusharija, nibindi. Ifite ubushobozi bwo guhuza ibikoresho, umutekano mwinshi kandi ishobora kwaguka cyane.

Topology y'urusobe rw'itumanaho rya OCPP

1、OCPP2.0.1 Imiterere ya Porogaramu

Ikubiyemo ahanini modules zo kohereza amakuru, kwemerera, umutekano, imiterere, gusuzuma, gucunga firmware, gucunga ibikoresho no gusharija, nibindi. Igice cy'imikorere ya module (igice) muri protocole ya OCPP2.0.1:

2 transmission Kohereza amakuru (DataTransfer) module

Koresha libwebsockets y'isomero ry'abandi bantu kugira ngo ushyireho umurongo wa websockets na CSMS ya kure binyuze mu muyoboro w'amakuru kugira ngo uhuze amakuru; koresha rapidjson y'isomero ry'abandi bantu kuri

3, Isomo ryo Kwemerera (Uruhushya)

Uburyo bwo gutanga uburenganzira burimo RFID, buto yo gutangira, ikarita yo kubikuza/krediti, kode ya PIN, CSMS, idToken yo mu gace, ISO15118, uburenganzira bwo gukoresha interineti utari kuri interineti n'ibindi.

Urugero: Imbonerahamwe y'igihe cyo kwemerera CSMS

4, Isomo ry'Umutekano (Umutekano)

Moduli y'umutekano ikoresha module ya mbedtls RSA, ECC (Elliptic Curve) yo muri library kugira ngo ihishe kandi ikureho amakuru, na module ya X509 yo gucunga ibyemezo.

Urugero: Imbonerahamwe y'igihe cyo kuvugurura ibyemezo bya sitasiyo yo gushyushya

5, Ihererekanyamakuru (Ihererekanyamakuru)

Ibikorwa bivuga inzira yo gusharija imodoka ikoresha amashanyarazi hakoreshejwe icyuma gishyushya.

Muri OCPP2.0, ubutumwa bwose bujyanye n'ibikorwa bushyirwa mu butumwa , ibi bisimbura , , , n'ubundi butumwa muri OCPP1.6.

Imbonerahamwe y'Igihe: Tangira Ibikorwa - Shyiraho Ukoresho Ukoresheje Interineti

6, module ya MeterValues

Mu gihe cyo gukora ihererekanyabikorwa, igomba kohereza amakuru y’ibipimo byo mu gace kuri CSMS buri gihe, kugira ngo CSMS n’abakoresha bashobore gusobanukirwa aho ibikorwa bigeze mu gihe nyacyo.

Imbonerahamwe y'igihe: amakuru ajyanye n'ibipimo by'ibikorwa

7, Moduli y'Ikiguzi

Moduli yo kwishyura ni module nshya ya porogaramu muri OCPP2.0, ikoreshwa mu gutanga amakuru y'ibiciro n'ubwishyu ku bakoresha. Ikubiyemo ahanini:

-Mbere yo gushyushya, tanga amakuru arambuye ku biciro by'aho gushyushyachargeur y'imodoka ikoresha amashanyarazi ku rukuta.

-Mu gihe cyo kwishyuza, gutanga amakuru y'ikiguzi mu buryo nyabwo.

-Nyuma yo gusharija, gutanga amakuru ya nyuma yo gusharija.

(1) Imbonerahamwe y'igihe cy'amakuru y'ibiciro mbere yo kwishyuza:

(2) Imbonerahamwe y'igihe cy'amakuru yerekeye kwishyura mu gihe cyo kwishyuza

(3) Imbonerahamwe y'igihe cy'amakuru yerekeye gusharija nyuma yo gusharija

8, Moduli yo Gutanga Reservation

Gutanga reservation ni akazi kabugenewe, gashobora gushyirwaho n'umukoresha. Kubera ko nta sitasiyo nyinshi zo gushyushya ziharichargeur y'imodoka ikoresha amashanyarazi ku rukuta kandi urwego rw'imodoka zikoresha amashanyarazi ni ruto, abakoresha bagomba kwemeza ko ibikoresho byo gusharija ari ibyabo mbere y'igihe.

Imbonerahamwe y'igihe cyo kubika ibikoresho byabugenewe byo gusharija ahantu ho gusharijachargeur y'imodoka ikoresha amashanyarazi ku rukuta:

9, SmartCharging Module

Gushaja neza bivuga imyitwarire yo guhindura imbaraga zo gushaja uko bikenewe mu gihe cyo gushaja. Bikubiyemo ahanini:

-Gushyira imizigo mu gice cyo gusharija -Gucunga sisitemu yo hagati

-Gukoresha uburyo bwo gusharija bugezweho mu gace runaka -Gucunga sisitemu yo gucunga ingufu

Muri OCPP smart chargerchargeur y'imodoka ikoresha amashanyarazi ku rukuta Igenzura rigaragarira cyane cyane mu miterere y’ingufu zikoreshwa mu gushyushya, zikubiyemo imipaka yo kohereza ingufu ku gice cyo gushyushya mu gihe runaka.

Ibikubiye mu butumwa bw'imyirondoro yo kwishyuza (JSON):

10, Igice cy'isuzumabumenyi

Ikoreshwa mu gusuzuma ibibazo by'aho gusharija amashanyarazi hifashishijwe ikoranabuhanga ryo mu bwoko bwa "devise" (kure) binyuze mu kohereza dosiye irimo amakuru ajyanye n'isuzuma ry'ibibazo bivuye aho gusharija amashanyarazi.

Imbonerahamwe y'urukurikirane rw'amadosiye y'amakuru yo gusuzuma indwara:

Kode ijyanye n'isuzuma ry'amadosiye (igice):

11, Moduli yo gucunga firmware

Iyo sitasiyo yo gusharija ikeneye kuvugurura porogaramu ya firmware, CSMS izamenyesha sitasiyo yo gusharija igihe ishobora gutangira gukuramo porogaramu nshya ya firmware, kandi sitasiyo yo gusharija igomba kumenyesha CSMS nyuma ya buri ntambwe yo gukuramo no gushyiramo porogaramu nshya ya firmware.

Urugero: Imbonerahamwe y'igihe cyo kuvugurura firime (Igice cyayo)

Kode ijyanye no kuvugurura firmware (igice):

12, module ya DisplayMessage

Module y'ubutumwa bwo kwerekana ikoreshwa n'ushinzwe gusharija (CSO) mu kwerekana amakuru ajyanye no gusharija ku mukoresha, module y'ubutumwa bwo kwerekana ni imikorere mishya muri OCPP 2.0, cyane cyane irimo

- Gushyiraho ubutumwa bwo kwerekana ubutumwa butangwa na CSO

-Gare yo gusharijachargeur y'imodoka ikoresha amashanyarazi ku rukuta kohereza ubutumwa bwo kwerekana

Gushyiraho igishushanyo mbonera cy'igihe cyo kwerekana ubutumwa:
