基于单片机的垃圾分类系统设计

Design of Garbage Classification System Based on Microcontroller

为提高垃圾分类效率,设计基于单片机的垃圾分类系统。系统利用ESP32模组和科大讯飞语音服务实现语音识别与处理,通过串口将处理结果发送给主控芯片STM32L4,主控芯片通过控制舵机进而控制垃圾桶盖的开合,完成一次垃圾分类投放,并将分类结果通过Wi-Fi上传云平台。实验结果显示系统可以稳定、有效进行垃圾分类,识别准确率可达到90%。

In order to improve the efficiency of waste sorting,a waste sorting system based on microcontroller is designed.The system uses the ESP32 module and the iFLYTEK voice service to realize voice recognition and processing,and sends the processing result to the main control chip STM32L4 through the serial port.The main control chip controls the opening and closing of the lid of the trash can by controlling the steering gear to complete a garbage sorting and placing,and upload the classification results to the cloud platform via Wi-Fi.The experimental results show that the system can classify garbage stably and effectively,and the recognition accuracy can reach 90%.
