Design And Implementation For Intelligent File Transfer System Applied In Campus

With the development and maturity of the Internet of Things technology,more and more physical devices are connected to the Internet,and the era of Internet of Everything has arrived.At the same time,traditional lockers have also evolved into smart lockers on the express train of the Internet of Things,and have been widely used.The deployment of smart lockers has sprung up all over the country like bamboo shoots after a rain.Express lockers,Take-out cabinets are a typical success story.At present,electronic lockers and smart lockers represented by express cabinets and takeaway cabinets are common on campus.Electronic lockers have been criticized by school teachers and students due to frequent lack of ink,paper shortage and easy loss of paper barcodes.The express cabinets and takeaway cabinets on campus cannot meet the needs of the exchange of items on campus due to their single purpose and not under the control of the school.Although the developers of smart storage cabinets such as express cabinets and takeaway cabinets have realized the single-use problem of these products and intend to expand their functions,it is difficult to adjust after all.At present,there is no smart locker system in domestic universities that serves teachers and students,is rich in functions and is restricted by the school.This file transfer cabinet system is based on the idea of device modeling,uses a low-code modeling platform to maintain the state synchronization between the Android side and the server side,and combines technologies such as "Spring Cloud+Ant Design+MyBatis+MySQL+jwt+Spring Security".According to the actual needs of each user,three user terminals and server terminals are provided:web,WeChat applet and Android APP.The web side is for system administrators and is used to provide support for system maintenance such as cabinet management and user management.The WeChat Mini Program is for secretaries,teachers and students on campus,providing functions such as the management and opening of the cabinets according to different roles.The Android APP is installed in the terminal in front of the cabinet and provides auxiliary functions such as opening the door with the opening code and advertising.It solves the problems left in the lockers on campus and has good development prospects.At present,the system has been launched and tested in our school,and has achieved good results,and has received unanimous praise from teachers and students of the school.
