Abstract:

Intelligent power gateway is used for real-time collection,storage and analysis of data in substation or distribution station.The traditional intelligent power gateway does not support any Internet of things (IOT) communication protocol,so it is difficult to access the cloud platform.MQTT protocol is a widely used in the field of Internet of things communication.By studying the architecture and communication process of MQTT,a MQTT protocol library is compiled in the intelligent power gateway,which makes gateway have the ability to directly access cloud platform.Then a test has been done to verify the conformance and generality of MQTT library.

Key words: intelligent power gateway, real-time collection, Internet of things, MQTT
