Design of voice recognition of intelligent household waste classification system

This paper designs a kind of voice recognition intelligent waste classification system in order to solve the complex household waste and difficult classification. This system consists of mechanical part and control part. The mechanical part completes the design with SolidWorks 3D design software. Based on the control core of STM32 chip, the control system integrates the human body sensing, infrared distance measurement, voice recognition, voice broadcast, serial communication, man-machine interactive module and other modules. The system is able to give a prompt when the wastes are full and conduct man-machine interaction with users. It can recognize the names of the wastes by users, judge the properties of the wastes and give a prompt. The mechanical system and drive device can rotate and uncover the waste bins so as to classify the wastes intelligently. This device is of high accuracy, fast response, small volume, easy use and strong promotion value.
