Aiming at the problems existing in the classified delivery of campus garbage, this project puts forward a design scheme of the classified delivery system of campus garbage based on interactive experience. Students log in to the system through face recognition, select the type of garbage to be thrown in the system equipment interface and throw it out. The garbage sorting system automatically judges whether the garbage thrown by users is correctly classified and rewards users with points.
Users can check their own garbage types and related classification knowledge through the supporting client applet or the display screen on the system, so that college students can participate in the process of garbage classification, and then cultivate students' garbage classification habits and awareness. At the same time, sanitation workers can check the remaining capacity of garbage bins at various garbage drop points in the campus through the supporting APP. The efficient automatic classification of garbage by the system and the timely recovery and classification of spilled garbage by sanitation workers all play a positive role in improving the campus environment.

Campus garbage classification system
After the user passes the face recognition of the system, he logs into the system, and the throwing port of the garbage sorting device is opened, so that the user can throw the garbage into the throwing area; Then in the interactive world, the garbage they put in is preliminarily classified. After the device detects the garbage throwing, the user's operation is judged by convolutional neural network algorithm. If the user's classification is correct, the garbage will be separated into the corresponding trash can in combination with mechanical control, and the information of garbage classification will be saved in the user account, and the system will reward points to the user account; If the classification of users is incorrect, the system will re-classify and release users according to the recognition results, and the system will also give users less reward points. Users can view their own garbage classification information and points obtained through WeChat applet; Administrators use the supporting APP of the system to check the situation of each garbage classification and delivery point in the school. If the garbage is about to overflow, the system can push information to remind the administrator to deal with it in time, thus improving the efficiency of garbage disposal.
Wechat applet is aimed at students. In order to improve the interactive experience, a WeChat applet is designed. The applet takes Huawei P40 screen size as the design standard, uses WeChat development tools as the front-end development tools, uses mobile phones and PC development tools for remote debugging, uses WXML files to carry the basic view structure of the page, and uses WXSS files to control the display style of the page. By accessing the cloud server and using the function of WeChat applet, it can communicate with the relevant PI interfaces in the garbage classification system in real time. As a leading provider of open source cloud services in China, Zhizhiyun can provide efficient and stable network-side services. Student users can interact and communicate with the system only through the commonly used WeChat applet, and view the personal login information and the points obtained by personal garbage classification.

The management APP is designed for managers such as sanitation workers, and a management APP supporting the system is designed. Adopt mixed development; Xcode is selected as the development tool, and SQLite database is used to realize development and debugging. By associating SQLite, you can use SQLite open source database, which saves a lot of tedious steps in configuring environment variables. The management APP communicates with the main control board in real time through WiFi, and the real-time data upload between the mobile phone management APP and the interactive interface is realized through the 8-byte communication protocol. Through the function module of the APP, you can track and check the capacity of trash cans at various garbage drop points in schools in real time. If the garbage in the trash can is about to overflow, the system will send data through the management APP to remind the administrator to clean it up in time.
