基于ZigBee节点的智能家居系统语音控制设计

摘要

为实现基于S3C6410核心处理器与ZigBee技术的智能家居系统的语音控制,研究设计了基于SPCE061A单片机的ZigBee语音子节点.凌阳单片机SPCE061A能够进行语音信号的采集、处理以及语音识别,并与无线射频芯片CC2530之间通过串口进行通信.由语音识别系统以及ZigBee无线收发模块等所组成的语音子节点通过ZigBee无线网络与网关进行通信,通过网关来控制其他的ZigBee子节点.该系统实现了对开关型以及红外型家电的智能语音控制.该智能家居语音控制系统具有识别率高,控制使用方便等特点,有一定的发展前景.%In order to realize the speech control of the smart home system based on S3C6410 core processor and ZigBee technologies, a ZigBee voice sub-node based on Lingyang MCU SPCE061A was designed. The MCU can collect, process and recognize the speech signal, and communicate with the wireless RF CC2530 chip though the serial port. This speech sub-node composed of the speech recognition system and wireless transceiving module can communicate with the gateway though ZigBee wireless network, and then control other ZigBee sub-nodes though the gateway. The speech control on the switch-type and infrared type of the smart home systems was realized. This smart home system with high recognition rate has a bright future and is convenient ID use.
