基于STM32单片机的智能插座设计

Intelligent Socket Design Based on STM32 SCM

系统以STM32F103C8T6单片机为核心,以电压采样、电流采样、放大电路、电压电流降压电路以及电压电流比较电路等相应外围模块为主要电路,构成了一个智能插座系统。单片机内采用FFT算法,将采集的电压电流汇总进行分析,得到单个电器或多个电器组合用电时不同的频谱特性,从而识别插座上各种电器的使用情况。

This system is based on STM32F103C8T6 microcontroller as the core,with voltage and current sampling,amplifying circuit,voltage and current buck circuit,voltage and current comparison circuit and other corresponding peripheral modules as the main circuit,forming an intelligent socket system.FFT algorithm is used in the single chip microcomputer to draw the collected voltage and current for analysis,so as to obtain the different spectrum characteristics of a single electrical appliance or a combination of multiple electrical appliances,so as to identify the use of various electrical appliances on the socket.
