Internet of Vehicles based on MQTT protocol

Abstract

The invention provides an Internet of Vehicles based on an MQTT protocol. The Internet of Vehicles based on MQTT protocol comprises a plurality of electric vehicles, an Internet of Vehicles monitoring center and a plurality of mobile communication terminals, each electric vehicle comprises a first communication module, the Internet of Vehicles monitoring center comprises a second communication modules, each mobile communication terminal comprises a third communication module, the second communication module communicates with each first communication module and each third communication module through the MQTT protocol, each first communication module is used for transmitting the state information of the corresponding electric vehicle to the Internet of Vehicles monitoring center, and the Internet of Vehicles monitoring center processes the received state information of each electric vehicle and releases the processed state information to the corresponding mobile communication terminal according to the theme subscribed by each mobile communication terminal.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of the Internet of Vehicles, in particular to an Internet of Vehicles based on the MQTT protocol. [0003] 【Background technique】 [0004] With the country's strong support for the electric vehicle industry, the prospects for the development of the electric vehicle industry are becoming more and more broad. With the development of the electric vehicle industry, various technologies of electric vehicles are continuously improving. At present, the electric vehicle network system is still in the development stage. The vehicle network system uses the GPRS mobile network and the BMS system to share the information and data of the battery management system. Due to its low cost and easy implementation, it occupies a dominant position in China. However, the GPRS network is a low-bandwidth and unreliable communication network. The GPRS network needs to maintain a long connection for a long time, and it is ea...

At present, the electric vehicle network system is still in the development stage. The vehicle network system uses the GPRS mobile network and the BMS system to share the information and data of the battery management system. Due to its low cost and easy implementation, it occupies a dominant position in China. However, the GPRS network is a low-bandwidth and unreliable communication network. The GPRS network needs to maintain a long connection for a long time, and it is easy to disconnect or even crash when the signal is not good. If there is no efficient and suitable network communication protocol, not only It will increase the power consumption of vehicle equipment, increase network traffic, and cause system instability, directly affecting customer experience
