State Grid Corporation of China (SGCC) has put forward the decision of building “three types and two networks”, which makes the energy Internet enterprises more competitive. With the goal of reaching the first-class level in the world, they are confident to meet greater challenges. To a certain extent, the power Internet of things has a great impact on the enterprises in the power industry, but also faces a huge impact and challenge. Based on the analysis of the current situation of China’s electric power enterprises, this paper puts forward the research of ubiquitous power Internet of things and IPv6 Technology in wireless access terminal and intelligent meter reading application system. Through the investigation and analysis of 180 staff of an electric power enterprise in China, this paper compares the cost, rationality and efficiency of traditional power mode and IPv6 technology power mode, and discusses and analyzes the results. It is concluded that after the introduction of IPv6 technology into the power industry, the cost of the enterprise is saved, the rationality of the structure is improved, and the benefit of the power enterprise is also significantly improved, which provides technical guarantee for the development of the power enterprise. The research in this paper has important practical significance for further promoting the application of ubiquitous power Internet of things and IPv6 Technology in wireless access terminal and intelligent meter reading application in power enterprises.
