Protocol ya OCPP imapereka njira yolumikizirana yolumikizana pakati pa malo opangirawallbox magetsi galimoto charger ndi dongosolo lililonse loyang'anira. Zomangamanga za protocol izi zimathandizira kulumikizana kwa kulipiritsa kulikonsewallbox magetsi galimoto charger dongosolo lapakati la opereka chithandizo ndi ma post onse olipira.
I. OCPP Protocol
1. Dzina lonse la OCPP ndi Open Charge Point Protocol, yomwe ndi ndondomeko yaulere ndi yotseguka yopangidwa ndi OCA (Open Charge Alliance), bungwe lochokera ku Netherlands. The Open Charge Pointwallbox magetsi galimoto charger Protocol (OCPP) imagwiritsidwa ntchito pakulankhulana kogwirizana pakati pa malo ochapira (CS)wallbox magetsi galimoto chargerndi njira iliyonse yoyendetsera ma station station (CSMS). Kapangidwe ka protocol kameneka kamathandizira kulumikizana kwa CSMS ya wopereka chithandizo chilichonse ndi ma post onse olipira. Ubwino wa protocol ya OCPP: yotseguka komanso yaulere kugwiritsa ntchito, imalepheretsa kutsekeka kwa wopereka m'modzi (pulatifomu yotsatsa), imachepetsa nthawi yophatikizira / khama ndi nkhani za IT.
2, Mitundu yayikulu ya protocol ya OCPP
OCPP1.2(SOAP) OCPP1.5(SOAP) OCPP1.6(SOAP/JSON)
OCPP2.0.1 (JSON)
SOAP ili ndi malire ndi zopinga zake za protocol, sizingakhale zosiyanasiyana zokwezera mwachangu; JSON version ya WebSocket communication, ikhoza kukhala mu malo aliwonse ochezera a pa Intaneti kutumiza deta kwa wina ndi mzake, ma protocol omwe amagwiritsidwa ntchito kwambiri pamsika ndi 1.6J version, OCPP2.0.1 ndi 2018 kunja kwa protocol ikulimbikitsa kugwiritsa ntchito malangizo. zamtsogolo.
