Abstract: In view of the wide variety and large quantity of laboratory equipment,the equipment management work is complicated and cumbersome,the work intensity and pressure of laboratory management personnel are high.This paper proposes a laboratory equipment management system based on two-dimensional code technology and WeChat applet.Its functions include personnel management module,equipment management module and system management module.The equipment management module includes verification management,equipment borrowing management,equipment allocation management,equipment maintenance management,equipment obsolescence management,etc.The technology of the system uses a separate front-end and back-end architecture.The front-end includes the mobile terminal-WeChat applet and the PC terminal-Web browser,all using MVVM (Mo-del-View-ViewModel) design ideas.The back-end uses the SSM (SpringMVC＋Spring＋MyBatis) framework to achieve low-coupling,high-cohesion programs.Laboratory equipment uses QR codes as identification and marking,the operating cost is reduced and the efficiency is improved.The realization of this system reduces the repetitive workload of laboratory managers,improves the management efficiency of laboratory equipment,reduces management costs,and better promotes the scientific development of laboratories

Key words: Laboratory equipment management, MVVM, QR code technology, SSM, WeChat mini program
