基于LD3320的语音控制照明系统的设计

Design of Voice Control Lighting System Based on LD3320

随着电子技术的飞速发展,以及人们生活水平的提高,智能家居系统的概念开始走向大众.针对人们的需求,本文设计了一种语音控制家居照明系统.该系统运用STC11L08XE单片机,结合高性能语音识别芯片LD3320作为主控制模块,采用单片机与继电器作为照明系统中LED灯泡的控制节点.主控制模块与各控制节点之间通过n RF24L01无线收发芯片通信.实验结果表明该系统识别率高,可以准确地控制LED灯的亮灭.

With the rapid development of electronic technology, as well as the improvement of living standards, the concept of smart home system began to move to the public. In the light of people＇s demand, a kind of voice control home lighting system is designed. The system uses STC11L08 XE microcontroller, combined with high performance speech recognition chip LD3320 as the main control module, using single-chip microcomputer and relay as the lighting system LED lamp control node. The main control module and the control node are connected through the n RF24L01 wireless transceiver chip. The experimental results show that the recognition rate of the system is high, and the LED lamp can be accurately controlled.
