The invention relates to an IPV6 (internet protocol version 6) technology based smart grid inspection system for the internet of things. The technology of the internet of things and the IPV6 technology are combined to replenish a normal RFID (radio frequency identification device) internet-of-things system, so that point-to-point communication with equipment can be realized in an inspection process, and the equipment can be controlled while data can be updated initiatively according to current conditions of the equipment. The system comprises an article layer, a network layer and a user layer, wherein the article layer is formed by equipment object nodes and a plurality of sensor nodes, the network layer comprises next-generation internet, and the user layer comprises communication equipment, a mobile terminal and a management platform. By taking full advantages of small size, low cost and easiness in arrangement and maintenance of sensors and quickness and wide coverage of the internet, the inspection process of electric power equipment is highly intelligent and automatic, and problems can be found timelier while manpower resources are saved.
