There are many kinds and quantities of relay protection equipment. In view of the traditional paper records combined with manual management, the operation and maintenance mode of relay protection equipment has many problems, such as heavy workload and easy to make mistakes. This paper analyzes the application value of two-dimensional code technology in the management of relay protection equipment, and uses the characteristics of two-dimensional code with large capacity, small size and high recognition rate, and applies it to the operation and maintenance of secondary equipment and the storage of asset information. By recording the information of each relay protection equipment in different stages of installation, operation, defect and return, the life cycle management of relay protection equipment is realized. Taking a specific secondary equipment as an example, the storage of equipment defects and asset information is realized through two-dimensional code technology. The results show that the two-dimensional code technology can solve the problems of inconsistent accounts and low efficiency in manual management, which is of great significance to improve the efficiency of on-site operation and maintenance of relay protection.
