Mulu wochapira-Kuyambitsa kwa protocol yolumikizirana OCPP

1. Chidziwitso cha protocol ya OCPP

Dzina lonse la OCPP ndi Open Charge Point Protocol, yomwe ndi ndondomeko yaulere komanso yotseguka yopangidwa ndi OCA (Open Charging Alliance), bungwe lomwe lili ku Netherlands. Open Charge Point Protocol (OCPP) Open Charge Point Protocol imagwiritsidwa ntchito pamayankho olumikizana olumikizana pakati pa malo ochapira (CS) ndi makina aliwonse owongolera ma station (CSMS). Zomangamanga za protocol izi zimathandizira kulumikizidwa kwa dongosolo lapakati la operekera chithandizo chapakati ndi milu yonse yolipiritsa, ndipo amagwiritsidwa ntchito makamaka pothana ndi zovuta zosiyanasiyana zomwe zimayambitsidwa ndi kulumikizana pakati pa ma network otsatsa payekha. OCPP imathandizira kasamalidwe ka kuyankhulana kosasunthika pakati pa malo othamangitsira ndi makina oyang'anira apakati pa ogulitsa aliyense. Kutsekedwa kwa maukonde oyitanitsa anthu pawokha kwadzetsa kukhumudwa kosafunikira kwa eni magalimoto amagetsi ambiri ndi oyang'anira katundu mzaka zambiri zapitazi, zomwe zidapangitsa kuyimba kwina kulikonse kuti apange mtundu wotseguka. Ubwino wa protocol ya OCPP: kutsegulidwa kuti mugwiritse ntchito kwaulere, kuletsa kutsekeka kwa wothandizira m'modzi (pulatifomu yotsatsa), kuchepetsa nthawi yophatikizira / kuchuluka kwa ntchito ndi nkhani za IT.

2. Chiyambi cha chitukuko cha mtundu wa OCPP

Mu 2009, kampani ya ku Dutch ElaadNL inayambitsa kukhazikitsidwa kwa Open Charging Alliance, yomwe imayang'anira kulimbikitsa ndondomeko yotsegulira OCPP ndi OSCP yotsegula yotsegula. Tsopano ya OCA; OCPP ikhoza kuthandizira mitundu yonse yamakina olipira.

3. Chiyambi cha mtundu wa OCPP

Monga momwe tawonetsera pansipa, kuchokera ku OCPP1.5 kupita ku OCPP2.0.1 yaposachedwa

(1) OCPP1.2(SOAP)

(2)OCPP1.5(SOAP)

Popeza pali ma protocol ambiri achinsinsi m'makampani omwe sangathe kuthandizira chidziwitso chogwirizana chautumiki ndi kulumikizana kwa magwiridwe antchito pakati pa mautumiki osiyanasiyana a ogwira ntchito, OCA idatsogola popanga protocol yotseguka ya OCPP1.5. SOAP imachepetsedwa ndi zopinga za protocol yake ndipo sizingakwezedwe mwachangu pamlingo waukulu.

OCPP 1.5 imalumikizana ndi dongosolo lapakati kudzera pa SOAP protocol pa HTTP kuti igwiritse ntchito malo opangira. Imathandizira izi: Zochita zakomweko komanso zoyambilira patali, kuphatikiza metering polipira

(3) OCPP1.6(SOAP/JSON)

Mtundu wa OCPP 1.6 umawonjezera kukhazikitsidwa kwa mtundu wa JSON ndikuwonjezera kuyitanitsa kwanzeru. Mtundu wa JSON umalumikizana kudzera pa WebSocket, yomwe imatha kutumizana data wina ndi mnzake pamalo aliwonse ochezera. Protocol yomwe imagwiritsidwa ntchito kwambiri pamsika pano ndi mtundu 1.6J.

Imathandizira ma data amtundu wa JSON potengera ndondomeko ya ma websockets kuti muchepetse kuchuluka kwa data (JSON, JavaScript Object Notation, ndi mtundu wopepuka wa kusinthana kwa data) ndipo imalola kuti munthu agwire ntchito pamanetiweki omwe sagwirizana ndi njira zolipirira paketi (monga intaneti yapagulu) . Smart charger: load balancing, central smart charger and local smart charger. Lolani malo opangira ndalama atumizenso zambiri zake (kutengera zomwe zili pakalipano), monga mtengo womaliza wa metering kapena momwe malo othamangitsira.

(4) OCPP2.0 (JSON)

OCPP2.0, yomwe idatulutsidwa mu 2018, imathandizira kukonza magwiridwe antchito, imawonjezera chitetezo, ndi kasamalidwe ka zida: imawonjezera ntchito zolipiritsa mwanzeru, za topologies zokhala ndi kasamalidwe ka mphamvu (EMS), olamulira am'deralo, komanso kuyitanitsa mwanzeru magalimoto amagetsi, Topology of charges station. ndi kasamalidwe ka siteshoni zolipirira. Imathandizira ISO 15118: Pulagi-ndi-sewero ndi zofunikira zolipiritsa mwanzeru pamagalimoto amagetsi.

(5) OCPP2.0.1 (JSON)

OCPP 2.0.1 ndi mtundu waposachedwa kwambiri, womwe unatulutsidwa mu 2020. Imapereka zinthu zatsopano ndi zosintha monga kuthandizira ISO15118 (plug ndi play), chitetezo chowonjezereka, ndi kuwongolera machitidwe onse.

Ngati mukufuna kudziwa zambiri za izi, chonde omasuka kulankhula nafe.
