Design of intelligent classified trash can based on STM32

Aiming at the problem of low efficiency of waste classification at the present stage, an intelligent classified waste bin based on STM32 single chip microcomputer is designed, which has the functions of automatic identification and classification of waste types. According to the functional requirements, six parts are designed: stepper motor garbage delivery module, garbage full load alarm module, openmv camera identification of multiple types of garbage module, environmental protection video publicity module, multiple communication modules and UCOS real-time operating system. Through the cooperation of each module, it can independently identify the types of garbage for delivery and realize garbage classification. Aiming at the problem of full load of garbage and the rotation angle of different garbage, the hardware part is designed. At the same time, the software design is completed by studying the working principle of openmv. After the prototype is assembled, the test data can be obtained for many times. The garbage identification success rate is high, which can better realize the function of independent garbage classification, so as to enhance the garbage classification ability at the present stage.
