Cov txheej txheem OCPP muab kev daws teeb meem kev sib txuas lus sib koom ua ke ntawm cov chaw them nqilub thawv them fais fab tsheb phab ntsa thiab txhua lub kaw lus tswj hwm hauv nruab nrab. Cov qauv txheej txheem no txhawb nqa kev sib txuas ntawm txhua qhov kev them nqilub thawv them fais fab tsheb phab ntsa lub kaw lus tswj hwm hauv nruab nrab ntawm tus neeg muab kev pabcuam nrog txhua qhov chaw them nqi.
I. Cov Txheej Txheem OCPP
1. Lub npe tag nrho ntawm OCPP yog Open Charge Point Protocol, uas yog ib qho kev cai pub dawb thiab qhib uas OCA (Open Charge Alliance), ib lub koom haum nyob hauv Netherlands tau tsim. Lub Open Charge Pointlub thawv them fais fab tsheb phab ntsa Cov Txheej Txheem (OCPP) yog siv rau kev sib txuas lus sib koom ua ke ntawm cov chaw them nqi (CS)lub thawv them fais fab tsheb phab ntsathiab txhua lub tshuab tswj chaw them nqi (CSMS). Cov qauv txheej txheem no txhawb kev sib txuas ntawm txhua tus neeg muab kev pabcuam them nqi CSMS nrog txhua qhov chaw them nqi. Cov txiaj ntsig ntawm OCPP protocol: qhib thiab pub dawb rau siv, tiv thaiv kev xauv rau hauv ib tus neeg muab kev pabcuam (lub platform them nqi), txo cov sijhawm / kev siv zog thiab cov teeb meem IT.
2, Cov qauv tseem ceeb ntawm OCPP protocol
OCPP1.2(SOAP) OCPP1.5(SOAP) OCPP1.6(SOAP/JSON)
OCPP2.0.1 (JSON)
SOAP raug txwv los ntawm nws tus kheej cov kev txwv ntawm cov txheej txheem, tsis tuaj yeem ua ntau yam kev txhawb nqa sai; JSON version ntawm WebSocket kev sib txuas lus, tuaj yeem xa cov ntaub ntawv rau ib leeg hauv txhua qhov chaw hauv network, cov txheej txheem siv ntau tshaj plaws hauv kev ua lag luam yog 1.6J version, OCPP2.0.1 yog 2018 tawm ntawm cov txheej txheem yog txhawb kev siv ntawm kev coj ntawm yav tom ntej.
3, qhov sib txawv ntawm ntau yam OCPP versionslub tsheb fais fab them nqi phab ntsar
OCPP1.* sib xws nrog cov qauv qis dua, OCPP1.6 sib xws nrog OCPP1.5, OCPP1.5 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 hom ntawv ntawm cov ntaub ntawv xa tau txawv kiag li, OCPP2.0.1 ntxiv ntau ntawm OCPP1.6 tsis muaj qhov ua haujlwm, piv txwv li.
(1) StartTransaction thiab StopTransaction hauv OCPP1.6 raug hloov los ntawm TransactionEvent hauv OCPP2.0.1.
(2) Kev hloov kho firmware hauv OCPP2.0.1 ntxiv cov kos npe digital kom tiv thaiv kev rub tawm firmware tsis tiav, ua rau kev hloov kho firmware tsis ua haujlwm.
(3) Tus lej pauv nyiaj tau lees tias yuav tshwj xeeb los ntawm lub platform hauv OCPP1.6, thiab lav tias yuav tshwj xeeb los ntawm tus nqi them.lub thawv them fais fab tsheb phab ntsanyob rau hauv OCPP2.0.1.
(4) Hauv OCPP1.6, cov chaw tsis zoo tau raug kho kom zoo thiab hloov kho dua tshiab, piv txwv li: hauv OCPP1.6, cov ntaub ntawv transactionId hauv StartTransaction yog txiav txim siab los ntawm lub platform, tab sis hauv OCPP2.0.1, nws yog lub pawg them nqi.lub thawv them fais fab tsheb phab ntsa uas txiav txim siab tus nqi transactionId, uas yog qhov zoo vim tias thaum muaj kev ua tsis tiav ntawm lub network, nws yog qhov tsim nyog yuav tsum rov xa cov ntaub ntawv StartTransaction thaum lub pob them nqilub thawv them fais fab tsheb phab ntsa yuav tsum xa cov ntaub ntawv dua. Qhov zoo ntawm qhov no yog tias thaum muaj teeb meem hauv network, yuav tsum xa cov ntaub ntawv StartTransaction dua, yog tias nws yog OCPP1.6 version, lub platform yuav muaj peev xwm txuag tau ob daim qauv ntawm cov ntaub ntawv Transaction tib yam, ua rau cov neeg siv khoom cov nyiaj raug txiav ob zaug;
(5) OCPP 2.0.1 cov ntsiab lus thiab nta ntau dua li 1.6 version ntawm ntau ntxiv, kev txhim kho ntawm qhov nyuaj tau nce ntxiv.
Qhov thib ob, daim ntawv cog lus OCPP 2.0.1
OCPP2.0.1 txhawb kev siv cov ntaub ntawv websockets hom ntawv JSON, OCPP2.0.1 tsis sib xws nrog OCPP1.6.
Txhawb ntau txoj kev tso cai kev ruaj ntseg, ISO15118, kev them nyiaj ntse, kev tswj hwm khoom siv, kev tswj hwm kev them nyiaj, thiab lwm yam. Nta kev sib raug zoo siab, kev ruaj ntseg siab thiab kev nthuav dav siab.
