基于物联网的智能家居网关设计

摘要：随着家居设备智能化和环境舒适度需求的提高，本课题设计开发了融合多种通信技术的智能家居网关设备，作为智能家居系统的数据转发中心。智能家居网关采用STM32单片机硬件平台，首先通过ZigBee网络汇集采集终端的家居环境数据，再通过NB-IoT通信网络上传至云服务器，同时下发管理软件的控制命令。另外，网关配有语音识别模块，能够实现本地语音控制。经过系统测试，智能家居网关可完成数据转发功能，实现智能家居设备的远程监控。

Design and Implementation of Smart Home Gateway

Based on Internet of Things

Abstract：With the improvement of smart home technology and the requirements of environmental comfort, the smart home gateway is designed and developed in this paper which integrates a variety of communication technologies to forward the information as the data center of smart home system. Firstly, the smart home gateway collects the home environment data from the collection terminal with the ZigBee wireless network, and then uploads the data to the cloud server through the NB-IoT wireless network. Moreover, the smart home gateway can forward the control command of management software. In addition, the gateway is equipped with voice recognition module, which can realize local voice control.  The system test proves that the smart home gateway can forward the data and accomplish the remote monitoring of smart home devices.
