基于LD3320的智能LED照明系统研究

Research on the system of intelligent LED lighting based on LD3320

针对目前国内家居照明系统控制方式单一、智能化程度低等问题,提出了一种基于LD3320非特定人语音识别芯片的智能LED照明系统的构想。该系统以STM32F103ZET6为主控制器,通过SPI串行总线与LD3320通讯,控制器根据识别结果智能调节驱动3路白色LED灯的PWM占空比,实现人灯交流,智能调光的效果。该设计在智能家居领域具有较广的应用前景。

In order to solve the problem of simple control model and low intelligence in the smart lighting system, a system of intelligent LED lighting is proposed based on the non-specific speech recognition chip of LD3320.STM32F103ZET6 is the main controller in this system and communicates with LD3320 through the SPI serial bus.According to the recognition result, the controller intelligently adjusts the PWM duty cycle of the 3-channel white LED lamp.It comes true the human and lamp communication.It has the effect of the intelligent dimmer. The design has a wider application prospects in the field of intelligent home.
