China's power grid technology is developing towards informatization and intelligence. Targeted management platform research is one of the most effective construction and upgrading methods of power related projects. Based on the technology of image recognition and internet of things, a new substation facility management system is designed, which extracts the image feature points with surf recognition algorithm and calculates the feature vector through the euclidean distance method, so as to quickly identify the substation facility image, and use the established substation facility management system to provide diversified information such as engineering situation and facility status to the on-site construction personnel. At the same time, intelligent applications are developed under the hybrid architecture to support the use of a variety of intelligent mobile terminal devices. The development and use of this system can improve the construction efficiency of substation facilities, and then reduce the construction, reconstruction and supervision costs of related projects. Finally, the substation facility management system designed for a substation test institute verifies the reliability and effectiveness of the system.
