基于语音识别的智能垃圾分类箱设计

文中设计了一个基于人机交互的智能语音垃圾分类系统。该系统利用STM32控制LD3320语音模块进行语音识别，并由压力检测模块实时监测垃圾箱内的垃圾是否装满，且带有垃圾桶状态播报功能。该系统的整体设计包括硬件设计和软件设计两部分。硬件系统由单片机、语音模块和压力检测模块组成，软件系统由程序编程直接控制LD3320语音识别芯片，也可与单片机进行数据交互。在初始化系统及设置一些寄存器和变量时，需要对其赋予无关后续判断的初值，保证程序无干扰运行。该智能语音垃圾分类箱可帮助人们有效地进行垃圾分类，加强垃圾分类意识，具有较强的实用性。

Design of An Intelligent Garbage Sorting Bin Based on Voice Recognition

An intelligent voice garbage classification system based on human-machine interaction is designed in this paper. The system uses STM32 to control the LD3320 voice module for automatic speech recognition, and the pressure detection module monitors whether the garbage in the trash can is full in real time, and has the function of broadcasting the status of the trash can. The overall design of the system includes hardware design and software design. The hardware system consists of a single-chip microcomputer, a voice module and a pressure detection module. The software system directly controls the LD3320 automatic speech recognition chip by program programming, and can also interact with the single-chip microcomputer for data. When initializing the system and setting some registers and variables, it is necessary to give them the initial value of irrelevant subsequent judgment to ensure that the program runs without interference. The intelligent voice garbage sorting box can help people effectively classify garbage, strengthen the awareness of garbage classification, and has strong practicability.
