摘要：

摘要：针对智能家居内部网络低成本、短距离、低数据速率的通信与组网需求，设计了一种基于CC1101的433 MHz射频通信协议栈，并实现了以嵌入式操作系统μC/OS-II与微控制器STM32F407为基础的智能网关。该智能网关搭载Wi-Fi、GSM、网卡等功能模块，与433 MHz 射频通信协议栈协调工作实现了多种智能控制方式。详细介绍了433 MHz射频协议栈设计、通信协议与节点模型的定义、433 MHz射频网络组建、数据冲突退避与重发机制。该方案具有简单实用的特点，适合家庭内部网络使用。

Abstract:

According to the network establishing demands of the internal network of intelligent home, such as low cost, low data rate, short distance communication, a type of 433 MHz RF communication protocol stack based on CC1101 was created and a gateway based upon the embedded operating system called μC/OS-II and micro controller called STM32F407 was implemented. This intelligent gateway equipped with Wi-Fi, GSM, ethernet and other functional modules works with the 433 MHz RF communication protocol stack to achieve multiple intelligent controls. Specifically the following points were mainly presented: the design of 433 MHz RF protocol stack, the definition of communication protocol and node model, the establishment of 433 MHz RF network, and the mechanism of date collision avoidance and retransmission. Owing to simplicity and practicality, this scheme is suitable for the application in family internal network.

Key words: 433 MHz RF communication, intelligent gateway, 433 MHz RF communication protocol, CC1101, STM32F407
