The work aims to solve the technical problems of serialized management of ammunition, improve the level of product quality management, and realize the digital management of ammunition information. A database was established based on SQL Server 2019, and Python was used to create database management software to realize input, generation, identification, and comprehensive information query of ammunition product information. The system could realize the generation of ammunition product information in the form of QR code, and can identify the product information on the QR code and display related information. The ammunition packaging information management system based on QR code technology can improve the digitalization level of ammunition product information management. At the same time, it is also a practice to meet the needs of industrial automation production. It has great practical value and reference value.
