Abstract
In the context of the global energy crisis and severe environmental pollution, the Chinese government is actively promoting the implementation and development of new energy vehicles. As an important supporting infrastructure for the development of new energy vehicles, charging stations have very important social value and economic benefits. This paper takes electric vehicles as an example to explore the application research of Internet of Things technology in the operation and maintenance management system of charging stations. This article mainly explains the concept and architecture of the Internet of Things technology from the network infrastructure and protocol architecture, detailed analysis and description of each layer in the protocol specification. This article tests the relevant parameters in the network system, including data loss rate test and data transmission time. This paper studies the construction and structure of electric vehicle charging stations, and then introduces the design principles and key technologies of the operation and maintenance management platform for electric vehicle charging stations. These key technologies include communication protocol, development language and development platform selection, software architecture design, etc. The experimental results show that the data loss rate of the networking system is less than 3%, and the transmission delay is about 9ms. Therefore, the data collected in the networking system designed in this paper has the characteristics of timeliness and accuracy, and conforms to the current data information. Requirements can be used in practical applications.
