The Design and Implementation of ID Generator for Power Internet of Things

This paper analyzes the problems of equipment resource ID identification standard is not uniform and ID is not global unique in traditional power system. The power Internet of things integrates the traditional power system and manages all equipment resources. It needs to distinguish the ID of all devices, and requires that the ID produced have uniform specifications and global uniqueness. This paper designs an ID generator which can meet the above requirements. It mainly uses the operation atomicity of redis and the characteristics of database persistence, and combines with the concept design of ID segment to solve the problem of speed mismatch between redis and database. The results show that the ID generator designed in this paper not only meets the global uniqueness, but also has high efficiency. It is very suitable for assigning unique identification to equipment in the power Internet of things.
