多协议融合的智能家居无线网关的设计与实现

Design and Implementation of the Smart Home Wireless Gateway Based on Multi-protocol

现有智能家居网关或是功能不完整,或是数据传输复杂、灵活性差、成本高,难以满足智能家居系统便捷、灵活、廉价的要求.本文所述无线网关的设计,以STM32F103RBT6为主控芯片,融合了Wi Fi、GPRS和低成本n RF24L01无线通信模块,并使用自定义的内网无线通信协议,有效地解决了多协议融合及内网与外网数据转换的问题,实现了对家居情况的实时监控.

Existing functions of the smart home gateway are incomplete, with low flexibility, high cost, and complicated data transmission, and cannot adapt to the requirements for the hardware of the current home： Convenience, quickness, flexibility and low cost. In light of the requirements, a wireless gateway was designed based on the STM32F103RBT6, and it incorporated GPRS, WiFi and the low cost nRF24L01 module and adopted the custom internal network wireless communication protocol. The problem of the data conversion between internal and external networks was resolved effectively, achieving real-time monitoring of the smart home.
