Ndondomeko ya OCPP imapereka njira yolumikizirana yogwirizana pakati pa malo ochapirachochapira galimoto yamagetsi ya pakhoma ndi njira iliyonse yoyang'anira pakati. Kapangidwe ka protocol iyi kamathandizira kulumikizana kwa chaji iliyonsechochapira galimoto yamagetsi ya pakhoma Dongosolo loyang'anira pakati la opereka chithandizo ndi malo onse ochapira.

I. Ndondomeko ya OCPP

1. Dzina lonse la OCPP ndi Open Charge Point Protocol, yomwe ndi protocol yaulere komanso yotseguka yopangidwa ndi OCA (Open Charge Alliance), bungwe lomwe lili ku Netherlands.chochapira galimoto yamagetsi ya pakhoma Protocol (OCPP) imagwiritsidwa ntchito polumikizana kogwirizana pakati pa malo ochapira (CS)chochapira galimoto yamagetsi ya pakhomandi njira iliyonse yoyendetsera malo ochajira (CSMS). Kapangidwe ka protocol iyi kamathandizira kulumikizana kwa CSMS ya wopereka chithandizo chilichonse ndi malo onse ochajira. Ubwino wa protocol ya OCPP: yotseguka komanso yaulere kugwiritsa ntchito, imaletsa kutsekedwa kwa wopereka chithandizo chimodzi (nsanja yochajira), imachepetsa nthawi/khama lophatikizana ndi mavuto a IT.

2. Mabaibulo akuluakulu a protocol ya OCPP

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

OCPP2.0.1 (JSON)

SOAP ili ndi malire ndi zoletsa zake za protocol, sizingakhale ndi mitundu yosiyanasiyana ya kukwezedwa mwachangu; JSON mtundu wa kulumikizana kwa WebSocket, ukhoza kukhala mu netiweki iliyonse kuti utumize deta kwa wina ndi mnzake, ma protocol omwe amagwiritsidwa ntchito kwambiri pamsika ndi mtundu wa 1.6J, OCPP2.0.1 ndiye 2018 kuchokera pa protocol yomwe ikulimbikitsa kugwiritsa ntchito njira yamtsogolo.

3, kusiyana pakati pa mitundu yosiyanasiyana ya OCPPcholipiritsa chagalimoto chamagetsi cha pakhomar

OCPP1.* imagwirizana ndi mitundu yotsika, OCPP1.6 imagwirizana ndi OCPP1.5, OCPP1.5 imagwirizana ndi OCPP1.2.

OCPP2.0.1 sigwirizana ndi OCPP1.6, OCPP2.0.1 ngakhale zina mwa zomwe zili mu OCPP1.6 zilinso nazo, koma mawonekedwe a chimango cha data chotumizidwa akhala osiyana kwambiri, OCPP2.0.1 yowonjezera zambiri za OCPP1.6 ilibe ntchito, mwachitsanzo.

(1) StartTransaction ndi StopTransaction mu OCPP1.6 zalowedwa m'malo ndi TransactionEvent mu OCPP2.0.1.

(2) Kusintha kwa firmware mu OCPP2.0.1 kumawonjezera ma siginecha a digito kuti apewe kutsitsa kosakwanira kwa firmware, zomwe zimapangitsa kuti zosintha za firmware zilephereke.

(3) TransactionId ikutsimikiziridwa kuti ndi yapadera ndi nsanja mu OCPP1.6, ndipo ikutsimikiziridwa kuti ndi yapadera ndi positi yolipirira.chochapira galimoto yamagetsi ya pakhomamu OCPP2.0.1.

(4) Mu OCPP1.6, malo omwe anali ndi vuto akonzedwa bwino komanso kusinthidwa, mwachitsanzo: mu OCPP1.6, deta ya transactionId mkati mwa StartTransaction imatsimikiziridwa ndi nsanja, koma mu OCPP2.0.1, ndiye mulu wochapira.chochapira galimoto yamagetsi ya pakhoma zomwe zimatsimikiza mtengo wa transactionId, zomwe ndi zabwino chifukwa pakagwa vuto la netiweki, ndikofunikira kutumizanso deta ya StartTransaction pamene mulu wa chaji ukuchajidwa.chochapira galimoto yamagetsi ya pakhoma ayenera kutumizanso deta. Ubwino wa izi ndikuti ngati netiweki yalephera, muyenera kutumizanso deta ya StartTransaction, ngati ndi mtundu wa OCPP1.6, nsanjayo ikhoza kusunga makope awiri a deta yomweyo ya Transaction, zomwe zimapangitsa kuti kasitomala achotse ndalama kawiri;

(5) Zambiri ndi mawonekedwe a OCPP 2.0.1 kuposa mtundu wa 1.6 wa zambiri, kukula kwa zovuta kwawonjezeka.

Chachiwiri, mgwirizano wa OCPP 2.0.1

OCPP2.0.1 imathandizira kugwiritsa ntchito njira yolumikizirana ya JSON format data websockets, OCPP2.0.1 sigwirizana ndi OCPP1.6.

Imathandizira njira zingapo zovomerezeka zachitetezo, ISO15118, kuyatsa mwanzeru, kuyang'anira zida, kuyang'anira kuyatsa, ndi zina zotero. Imakhala ndi mgwirizano wapamwamba, chitetezo chapamwamba komanso kukula kwakukulu.

Topology ya Network ya OCPP

1、OCPP2.0.1 Kapangidwe ka Mapulogalamu

Makamaka imaphatikizapo ma module otumizira deta, chilolezo, chitetezo, kasinthidwe, kuzindikira, kasamalidwe ka firmware, kasamalidwe ka chipangizo ndi kasamalidwe ka chaji, ndi zina zotero. Gawo la magawo ogwirira ntchito (gawo) mu protocol ya OCPP2.0.1:

2, Kutumiza kwa data (DataTransfer) gawo

Gwiritsani ntchito laibulale ya chipani chachitatu libwebsockets kuti mukhazikitse kulumikizana kwa websockets ndi CSMS yakutali kudzera mu netiweki kuti mulumikizane ndi deta; gwiritsani ntchito laibulale ya chipani chachitatu rapidjson kuti

3, Chilolezo (Chilolezo) Module

Njira zovomerezeka zikuphatikizapo RFID, batani loyambira, khadi la debit/credit, PIN code, CSMS, local idToken, ISO15118, chilolezo cha offline ndi zina zotero.

Chitsanzo: Tchati cha Nthawi Yovomerezeka ya CSMS

4, Gawo la Chitetezo (Chitetezo)

Gawo lachitetezo limagwiritsa ntchito gawo lachitatu la laibulale ya mbedtls RSA, gawo la ECC (Elliptic Curve) kuti lisunge ndi kuchotsa deta, ndi gawo la X509 kuti liyang'anire ziphaso.

Chitsanzo: Chithunzi cha nthawi yosinthira satifiketi ya malo ochajira

5, Gawo la Zochita (Zochita)

Kugulitsa kumatanthauza njira yochajira galimoto yamagetsi pogwiritsa ntchito chipangizo chochajira.

Mu OCPP2.0, mauthenga onse okhudzana ndi zochitika amaphatikizidwa mu uthengawo , zomwe zimalowa m'malo mwa , , , ndi mauthenga ena mu OCPP1.6.

Chithunzi cha Nthawi: Yambani Kugulitsa - Pulagi ndi Kusewera

6, gawo la MeterValues

Pa nthawi yogulitsa, imafunika kutumiza deta ya mita yapafupi ku CSMS nthawi ndi nthawi, kuti CSMS ndi ogwiritsa ntchito athe kumvetsetsa momwe malondawo akuyendera nthawi yeniyeni.

Chithunzi cha nthawi: deta yokhudzana ndi mita yokhudzana ndi zochitika

7, Mtengo wa Gawo

Gawo lolipirira ndi gawo latsopano la mapulogalamu mu OCPP2.0, lomwe limagwiritsidwa ntchito popereka zambiri zamitengo ndi zolipirira kwa ogwiritsa ntchito. Makamaka limaphatikizapo:

- Musanayike chaji, perekani zambiri zamtengo wa siteshoni yoyikira chajichochapira galimoto yamagetsi ya pakhoma.

-Pa nthawi yolipiritsa, kupereka zambiri za mtengo weniweni.

-Mukatha kuchaja, perekani zambiri zomaliza zochaja.

(1) Chithunzi cha nthawi cha zambiri zamtengo musanalipire:

(2) Tchati cha nthawi yodziwira zambiri zolipirira panthawi yolipiritsa

(3) Chithunzi cha nthawi ya chidziwitso cha kuyitanitsa pambuyo poyitanitsa

8, Gawo Losungitsa Malo

Kusungitsa malo ndi ntchito yosungidwa, yomwe ingathe kukhazikitsidwa ndi woyendetsa. Popeza palibe malo ambiri ochapirachochapira galimoto yamagetsi ya pakhoma ndipo kuchuluka kwa magalimoto amagetsi komwe magalimoto amayendetsa kuli kochepa, ogwiritsa ntchito ayenera kukhala ndi zida zochajira pasadakhale.

Chithunzi cha nthawi yosungira zida zochapira zomwe zasankhidwa pamalo ochapirachochapira galimoto yamagetsi ya pakhoma:

9, Gawo Lochaja Mwanzeru

Kuchaja mwanzeru kumatanthauza khalidwe losintha mphamvu yochaja mosinthasintha ngati pakufunika panthawi yochaja. Makamaka limaphatikizapo:

-Kuyika katundu mkati mwa malo ochajira -Kulamulira kwapakati pa dongosolo

-Kuchaja mwanzeru kwanuko -Kuwongolera makina oyendetsera mphamvu

Mu OCPP smart chargingchochapira galimoto yamagetsi ya pakhoma Kuwongolera kumaonekera makamaka mu ma profiles a Charging, omwe ali ndi malire osamutsa mphamvu ya siteshoni yochapira panthawi inayake.

Zomwe zili mu uthenga wa ma profiles ochaja (JSON):

10, gawo la matenda

Imagwiritsidwa ntchito kuzindikira mavuto a malo ochapira pogwiritsa ntchito fayilo yokhala ndi chidziwitso chodziwira matenda kuchokera ku malo ochapira.

Chithunzi chojambulira fayilo yodziwitsa za matenda:

Khodi yokhudzana ndi fayilo yodziwitsa (gawo):

11, Gawo Loyang'anira Firmware

Pamene malo ochapira akufunika kusintha firmware, CSMS idzadziwitsa malo ochapira pamene ingayambe kutsitsa firmware yatsopano, ndipo malo ochapira ayenera kudziwitsa CSMS pambuyo pa sitepe iliyonse yotsitsa ndikuyika firmware yatsopano.

Chitsanzo: Chithunzi cha Nthawi Yosinthira Firmware (Pang'ono)

Khodi yokhudzana ndi zosintha za firmware (gawo):

12, gawo la DisplayMessage

Gawo la uthenga wowonetsa limagwiritsidwa ntchito ndi woyendetsa malo ochajira (CSO) kuwonetsa zambiri zokhudzana ndi kutchaji kwa wogwiritsa ntchito, gawo la uthenga wowonetsa ndi ntchito yatsopano mu OCPP 2.0, makamaka kuphatikiza

-Konzani uthenga wowonetsedwa ndi CSO

-Powonjezererachochapira galimoto yamagetsi ya pakhoma kukweza uthenga wowonetsa

Kukhazikitsa chithunzi cha nthawi yowonetsera uthenga:
