基于语音识别的家居智能监控系统
摘 要
智能家居系统大体而言可分为高层的信息娱乐网络和底层的数据采集与网络控制，在底层以微控制器为核心作为智能家居网络结点是目前智能家居的主要实现方式，语音识别技术在我国的研究成果也不是很高，但是用语音识别技术来与家居智能控制相结合是非常创新的。
本设计是采用AT89C52单片机为核心控制器的智能家居监控系统，系统通过无线nrf905作为信息传输媒介，将语音识别软件收到的具体指令发送至现场对单片机进行控制，从而控制家居的动作；同时现场单片机将数据通过无线发送至主控单片机，通过PC界面实时监控家居各模块的运行状态。
该系统的功能模块分为：语音控制窗帘模块、温度检测模块、火焰检测模块和防盗报警模块。通过C#编程，在Microsoft Speech SDK的基础上实现对家具的智能监控，在PC机界面上直观的看到家居所有情况。

Speech recognition-based smart home monitoring system
Abstaract
Generally speaking the smart home system can be divided into high-level information and entertainment network，the underlying data collection and network control in the bottom to the microcontroller as the core as a smart home network node，this is the main achievement of smart home way，the speech recognition technology inour research is not very high，but the voice recognition technology to the home intelligent combination of the control is very innovative.
The design is using AT89S52 MCU core controller intelligent home monitoring system， the system through wireless nrf905 as information transmission medium，that specific instructions received by the voice recognition software is sent to the scene to control the MCU to control the actions of home；at the same time the scene SCM data through the wireless sent to the host microcontroller，real-time monitoring via a PC interface home run of the module state.
The functional modules of the system is divided into，the voice control the curtains module temperature detection module，the flame detection module，and burglar alarm module. On the basis of the Microsoft Speech SDK， C # Programming，intelligent monitoring of the furniture intuitive interface of the PC，see the home in all cases.
