摘要：本文介绍的是一种基于蓝牙技术、语音识别技术的智能家庭控制中心系统。伴随着电子计算机技术、网络通信技术、控制技术及人工智能技术的飞跃发展，智能化已成为当前科技发展的新趋势。大众越来越注意自己生活环境的舒适与便利性，在这种条件与需求的碰撞中，智能家居应运而生。无线化、智能化是发展的趋势。

本课题主要是研究语音识别技术、蓝牙数据传输技术和嵌入式系统。通过对三种技术的结合应用，设计出一种能够智能采集识别人声，并执行相关命令的家庭控制中心系统。其中语音识别模块选用的是ICRoute公司设计生产的LD3320非特定人语音识别芯片，负责人声的采集与识别。蓝牙模块选用的是与单片机配套的HC-05，通过HC-05传输指令。家庭控制中心的核心处理器是STM32F103，实现对各模块的调用以及功能实现。

系统通过语音识别模块对采集到的人声进行识别，再通过单片机板载蓝牙模块将识别出来的指令通过蓝牙透传的方式发送到从机，从机端控制板执行接收到的指令以实现对家电设备的控制。本课题在实现上述基本功能的前提下初步探求智能家居的一种无线化、智能化的控制方案。

Abstract：This paper introduces an intelligent home control center system based on Bluetooth technology and speech recognition technology. With the rapid development of electronic computer technology, network communication technology, control technology and artificial intelligence technology, intelligence has become a new trend in the development of science and technology. The public pay more and more attention to the comfort and convenience of their living environment. In the collision of this condition and demand, the smart home emerges as the times require. Wireless and intelligent is the trend of development.

This topic is mainly to study speech recognition technology, Bluetooth data transmission technology and embedded system. Through the combination and application of the three technologies, a family control center system is designed, which can intelligently collect and recognize human voices and execute related commands. Among them, the speech recognition module is chosen by ICRoute company to design and manufacture LD3320 non- specific speech recognition chip, which is responsible for the acquisition and recognition of human voices. Bluetooth module is selected with the MCU matching HC-05, through the HC-05 transmission instructions. The core processor of the home control center is STM32F103, which implements the call and function realization of each module.

The system through the voice recognition module of the collected voice recognition, and then through the microcontroller onboard Bluetooth module will be identified from the machine instructions to send fax via Bluetooth through the way board received instructions to implement control of appliances from end control. Under the premise of realizing the above basic functions, this subject explores a wireless and intelligent control scheme of smart home.
