OCPP raws tu qauv muab kev sib txuas lus sib koom ua ke ntawm cov chaw them nqiwallbox fais tsheb charger thiab txhua qhov kev tswj hwm hauv nruab nrab. Cov txheej txheem tsim qauv no txhawb kev sib txuas ntawm kev them nyiajwallbox fais tsheb charger tus neeg muab kev pabcuam lub hauv paus tswj kev tswj hwm nrog txhua qhov kev them nqi.
I. OCPP raws tu qauv
1. Lub npe tag nrho ntawm OCPP yog Open Charge Point Protocol, uas yog cov txheej txheem pub dawb thiab qhib tsim los ntawm OCA (Open Charge Alliance), lub koom haum nyob hauv Netherlands. Qhib Charge Pointwallbox fais tsheb charger Txoj Cai (OCPP) yog siv rau kev sib txuas lus sib koom ua ke ntawm cov chaw them nqi (CS)wallbox fais tsheb chargerthiab txhua qhov chaw them nqi tswj hwm qhov system (CSMS). Cov txheej txheem kev tsim qauv no txhawb kev sib txuas ntawm txhua tus neeg muab kev pabcuam them nqi CSMS nrog rau tag nrho cov nqi them. Qhov zoo ntawm OCPP raws tu qauv: qhib thiab siv dawb, tiv thaiv kev xauv nkag rau hauv ib tus neeg muab kev pabcuam (them lub platform), txo cov sijhawm sib koom ua ke / kev siv zog thiab IT teeb meem.
2, Cov qauv tseem ceeb ntawm OCPP raws tu qauv
OCPP1.2(SOAP) OCPP1.5(SOAP) OCPP1.6(SOAP/JSON)
OCPP 2.0.1 (JSON)
SOAP yog txwv los ntawm nws tus kheej cov txheej txheem txwv, tsis tuaj yeem ua ntau yam ntawm kev nce qib sai; JSON version ntawm WebSocket kev sib txuas lus, tuaj yeem nyob hauv ib puag ncig network xa cov ntaub ntawv mus rau ib leeg, cov txheej txheem siv ntau tshaj plaws ntawm kev ua lag luam yog 1.6J version, OCPP2.0.1 yog 2018 tawm ntawm cov txheej txheem yog txhawb kev siv cov kev taw qhia. ntawm yav tom ntej.
3, qhov sib txawv ntawm ntau yam OCPP versionswallbox fais tsheb themr
OCPP1.* yog sib xws nrog qis versions, OCPP1.6 yog sib xws nrog OCPP1.5, OCPP1.5 yog sib xws nrog OCPP1.2.
OCPP2.0.1 tsis sib xws nrog OCPP1.6, OCPP2.0.1 txawm hais tias qee cov ntsiab lus ntawm OCPP1.6 kuj muaj, tab sis cov qauv ntawm cov ntaub ntawv xa tawm tau txawv kiag li, OCPP2.0.1 ntxiv ntau OCPP1.6 ua. tsis muaj lub luag haujlwm, piv txwv li.
(1) StartTransaction thiab StopTransaction hauv OCPP1.6 yog hloov los ntawm TransactionEvent hauv OCPP2.0.1.
(2) Firmware hloov tshiab hauv OCPP2.0.1 ntxiv cov kos npe digital los tiv thaiv kev rub tawm tsis tiav firmware, ua rau firmware hloov tshiab ua tsis tiav.
(3) Kev lag luamId tau lees paub tias nws yog qhov tshwj xeeb los ntawm lub platform hauv OCPP1.6, thiab lav tias nws yog qhov tshwj xeeb los ntawm kev them nqiwallbox fais tsheb chargerhauv OCPP2.0.1.
(4) Hauv OCPP1.6, qhov chaw tsis zoo tau raug kho kom zoo thiab hloov kho dua tshiab, piv txwv li: hauv OCPP1.6, cov ntaub ntawv sib pauv hloov pauv hauv StartTransaction yog txiav txim siab los ntawm lub platform, tab sis hauv OCPP2.0.1, nws yog pawg them nyiaj.wallbox fais tsheb charger uas txiav txim siab tus nqi transactionId, uas yog qhov zoo vim tias thaum muaj kev tsis ua haujlwm hauv lub network, nws yuav tsum rov xa cov ntaub ntawv StartTransaction thaum lub them pawgwallbox fais tsheb charger yuav tsum xa cov ntaub ntawv dua. Qhov kom zoo dua ntawm qhov no yog tias thaum muaj kev tsis ua haujlwm hauv lub network, yuav tsum rov xa cov ntaub ntawv StartTransaction, yog tias nws yog OCPP1.6 version, lub platform muaj peev xwm txuag tau ob daim ntawv theej ntawm tib cov ntaub ntawv Transaction, uas ua rau kev txiav tawm ntawm lub platform. cov neeg siv nyiaj ob zaug;
(5) OCPP 2.0.1 cov ntsiab lus thiab cov yam ntxwv tshaj li 1.6 version ntawm ntau ntau, kev txhim kho ntawm qhov nyuaj tau nce.
