Application of the internet of things technology in power transmission equipments condition monitoring

Smart grid is one of the most important application fields in the internet of things （IOT）. On the basis of integrated analysis of basic concept and research hotspot of IOT, the paper preliminary studies the application prospects of IOT in on-line monitoring of power transmission and distribution equipment, electric vehicle and smart home. Then, with intelligent monitoring, condition assessment and life cycle management of transmission and distribution equipment as background, architecture of the internet of power transmission and distribution equipment is proposed, including intelligent perception layer, data communication layer, information integration layer, smart application layer. Key technologies, such as integrated intelligent monitoring device, coding and labeling system, communication technology, panoramic information modeling, information processing, life cycle management, security problems and standardization, are further discussed in detail. And then research directions and existing problems of these technologies are finally given.
