Iyo OCPP protocol inopa yakabatana yekutaurirana mhinduro pakati pezviteshi zvekuchajawallbox yemagetsi mota charger uye chero central management system. Iyi protocol architecture inotsigira kubatana kwechero kuchajawallbox yemagetsi mota charger service provider's central management system ine zvese zvekuchaja posts.

I. OCPP Protocol

1. Zita rakazara reOCPP iOpen Charge Point Protocol, inova purogiramu yakasununguka uye yakazaruka yakagadzirwa neOCA (Open Charge Alliance), sangano rinogara muNetherlands. Iyo Open Charge Pointwallbox yemagetsi mota charger Protocol (OCPP) inoshandiswa kutaurirana kwakabatana pakati pezviteshi zvekuchaja (CS)wallbox yemagetsi mota chargeruye chero yekuchaja chiteshi manejimendi system (CSMS). Iyi protocol architecture inotsigira kubatana kwechero kuchaja sevhisi CSMS ine zvese zvekuchaja mapositi. Zvakanakira zveOCPP protocol: yakavhurika uye yakasununguka kushandisa, inodzivirira kukiya-mukati kune mumwe chete mupi (kuchaja chikuva), inoderedza yekubatanidza nguva / kuedza uye IT nyaya.

2、Main versions eOCPP protocol

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

OCPP2.0.1 (JSON)

SIPO inoganhurirwa neyayo yeprotocol constraints, haigone kuve yakawanda yekukurumidza kukwidziridzwa; JSON shanduro yeWebSocket communication, inogona kuva mune chero network network kutumira data kune mumwe nemumwe, iyo inonyanya kushandiswa mitemo pamusika ndeye 1.6J version, OCPP2.0.1 ndiyo 2018 kunze kweprotocol iri kukurudzira kushandiswa kwegwaro. remangwana.

3, misiyano pakati peakasiyana OCPP shandurowallbox yemagetsi mota charger

OCPP1.* inowirirana neshanduro dzakaderera, OCPP1.6 inopindirana neOCPP1.5, OCPP1.5 inopindirana neOCPP1.2.

OCPP2.0.1 haienderani neOCPP1.6, OCPP2.0.1 kunyangwe zvimwe zviri mukati meOCPP1.6 zvinewo, asi chimiro che data rakatumirwa chakasiyana zvachose, OCPP2.0.1 yakawedzera yakawanda OCPP1.6 inoita. isina basa, semuenzaniso.

(1) StartTransaction uye StopTransaction muOCPP1.6 inotsiviwa neTransactionEvent muOCPP2.0.1.

(2) Firmware update muOCPP2.0.1 inowedzera masiginecha edhijitari kudzivirira kudhawunirodha kusina kukwana firmware, zvichiita kuti firmware update kukundikana.

(3) Iyo transactionId inovimbiswa kuve yakasarudzika nepuratifomu muOCPP1.6, uye inovimbiswa kuve yakasarudzika neyekuchaja positi.wallbox yemagetsi mota chargermuOCPP2.0.1.

(4) MuOCPP1.6, nzvimbo dzakaremara dzakagadziridzwa uye dzakakwidziridzwa, semuenzaniso: muOCPP1.6, iyo transactionId data mukati meStartTransaction inotarwa nepuratifomu, asi muOCPP2.0.1, ndiyo murwi wekuchaja.wallbox yemagetsi mota charger iyo inosarudza iyo transactionId kukosha, iyo inobatsira nekuti kana paine kutadza kwetiweki, zvinodikanwa kutumira zvakare iyo StartTransaction data kana murwi wekuchaja.wallbox yemagetsi mota charger inofanira kutumira data zvakare. Zvakanakira izvi ndezvekuti kana pane network kutadza, inoda kutumira zvakare StartTransaction data, kana iri OCPP1.6 vhezheni, chikuva chinogona kuchengetedza makopi maviri eiyo yakafanana Transaction data, zvichikonzera kuderedzwa kweiyo mari yemutengi kaviri;

Chechipiri, OCPP 2.0.1 chibvumirano

OCPP2.0.1 inotsigira kushandiswa kweJSON format data websockets communication, OCPP2.0.1 haienderani neOCPP1.6.

Inotsigira nzira dzakawanda dzekubvumidza kuchengetedzwa, ISO15118, smart kuchaja, manejimendi ezvishandiso, manejimendi ekuchaja, etc. Inoratidza kuenderana kwepamusoro, kuchengetedzwa kwepamusoro uye kukwirira kwakanyanya.

OCPP Network Topology

1, OCPP2.0.1 Software Architecture

Inonyanya kusanganisira ma modules ekutumira data, mvumo, kuchengeteka, kugadzirisa, kuongororwa, firmware management, device management uye kuchaja kutarisira, etc. Functional module division (chikamu) muOCPP2.0.1 protocol:

2, Kutumira data (DataTransfer) module

Shandisa yechitatu-bato raibhurari libwebsockets kumisikidza websockets yekubatanidza neiyo kure CSMS kuburikidza netiweki yekudyidzana kwedata; shandisa yechitatu-bato raibhurari rapidjson nokuda

3, Mvumo (Mvumo) Module

Nzira dzemvumo dzinosanganisira RFID, bhatani rekutanga, dhibhiti / kadhi rechikwereti, PIN kodhi, CSMS, idToken yemuno, ISO15118, mvumo yekusaita uye zvichingodaro.

Muenzaniso: CSMS Mvumo Nguva Yenguva

4, Chengetedzo (Chengetedzo) Module

Chengetedzo module inoshandisa yechitatu-bato raibhurari mbedtls RSA, ECC (Elliptic Curve) module kuvharidzira uye decrypt data, uye X509 module kubata zvitupa.

Muenzaniso: dhayagiramu yenguva yekuvandudza zvitupa zvekuchaja chiteshi

5, Transactions (Transactions) Module

Transactions zvinoreva nzira yekuchaja mota yemagetsi nemudziyo wekuchaja.

MuOCPP2.0, ese mameseji ane chekuita nekutengeserana anobatanidzwa mumeseji , iyo inotsiva , , , uye mamwe mameseji muOCPP1.6.

Nguva Dhiagiramu: Tanga Transaction - Plug uye Tamba

6, MeterValues module

Munguva yekutengeserana, inoda kutumira data yemamita emunharaunda kuCSMS nguva nenguva, kuitira kuti CSMS nevashandisi vanzwisise kufambira mberi kwekutengeserana munguva chaiyo.

dhayagiramu yenguva: data ine chekuita nemamita data

7, Mutengo Module

Billing module isoftware nyowani muOCPP2.0, iyo inoshandiswa kupa mutengo uye ruzivo rwekubhadhara kune vashandisi. Zvinonyanya kusanganisira:

-Usati wachaja, uchipa ruzivo rwakadzama rwemutengo wechiteshi chekuchajawallbox yemagetsi mota charger.

-Panguva yekuchaja, kupa chaiyo-nguva mutengo ruzivo.

-Mushure mekuchaja, kupa ruzivo rwekupedzisira rwekuchaja.

(1) Dhiagiramu yenguva yeruzivo rwemutengo usati wachaja:

(2) Chati yenguva yeruzivo rwekubhadharisa panguva yekuchaja

(3) Dhiagiramu yenguva yekuchaja ruzivo mushure mekuchaja

8, Reservation Module

Reservation ibasa rakachengetwa, iro rinogona kuiswa nemushandisi. Sezvo pasina nzvimbo dzakawanda dzekuchajawallbox yemagetsi mota charger uye huwandu hwekutyaira kwemotokari dzemagetsi hushoma, vashandisi vanofanirwa kuchengetedza muridzi wemidziyo yekuchaja pamberi.

dhiyagiramu yenguva yekuchengetera mudziyo wakatarwa wekuchaja pachiteshi chekuchajawallbox yemagetsi mota charger:

9, SmartCharging Module

Smart kuchaja inoreva maitiro ekugadzirisa zvine simba simba rekuchaja sezvinodiwa panguva yekuchaja. Zvinonyanya kusanganisira:

-Kutakura kuyera mukati mechiteshi chekuchaja -Central system control

-Local smart kuchaja -Energy management system control

MuOCPP smart kuchajawallbox yemagetsi mota charger kutonga kunonyanya kuratidzwa mumaprofiles ekuchaja, ayo ane miganho yekufambisa simba yechiteshi chekuchaja pane imwe nguva nenguva.

Kuchaja meseji yemeseji (JSON):

10, Diagnostics module

Inoshandiswa kuongorora kure kure matambudziko echiteshi chekuchaja nekuisa faira rine ruzivo rwekuongorora kubva kuchiteshi chekuchaja.

Diagnostic ruzivo faira kurodha sequence diagraph:

Diagnostic file inoenderana kodhi (chikamu):

11, Firmware Management Module

Kana chiteshi chekuchaja chichida kugadzirisa firmware, CSMS inozivisa chiteshi chekuchaja paichatanga kudhawunirodha firmware nyowani, uye chiteshi chekuchaja chinofanirwa kuzivisa CSMS mushure medanho rega rega rekurodha nekuisa iyo firmware itsva.

Muenzaniso: Firmware Yekuvandudza Nguva Dhiyagiramu (Pachikamu)

Firmware update inoenderana kodhi (chikamu):

12 、DisplayMessage module

Ratidza meseji module inoshandiswa neyekuchaja chiteshi opareta (CSO) kuratidza kubhadharisa ruzivo rwakabatana kumushandisi, iyo yekuratidzira meseji module ibasa idzva muOCPP 2.0, kunyanya kusanganisira

-Seta kuratidza meseji neCSO

-Charging stationwallbox yemagetsi mota charger kuisa meseji yekuratidzira

Kuseta dhiyagiramu yenguva yekuratidzira meseji:
