Abstract:

The “multi-service state grid e-ubiquitous power internet of things” proposed by the State Grid Corporation of China is the integration and evolution of the energy network and the internet of things,and is a key energy infrastructure serving the majority of users.With the rise of the power internet of things strategy,the online monitoring and acquisition nodes and monitoring scale of transmission lines will increase rapidly.What kind of technical system will be used to construct the on-site communication network? It is important to consider multiple factors such as long distance,low power consumption,and high reliability.The characteristics and advantages of wireless LoRa technology was researched,combined with the application scenarios and requirements of on-line transmission line monitoring,the schemes of online monitoring base on wireless LoRa networking were proposed and adaptability was analyzed ,the research results have certain reference significance in this field.

Key words: state grid e-ubiquitous internet of things, long range radio, transmission line, online monitoring, field communication network, LPWAN
