智能家居RF通信模块的设计与实现

Design and Implementation of RF Communication Module in Intelligence Home

针对智能家居终端设备的极大差异带来的网络接口不统一问题,设计了四线控制家电的RF通信模块,其接口简单,具有高兼容性。首先介绍了基于射频无线通信技术的智能家居系统,设计并实现了一款采用STM8S103F3单片机和CC1101无线收发器的通信模块,重点论述了通信模块的硬件及软件设计。用软件模拟FIFO(first input first output,先入先出队列)缓冲区确保不丢失数据,且发送数据前检查同频电磁波实现防冲突功能。测试表明,该无线通信模块能够满足低成本、低功耗和远距离无线传输的要求。

In view of the problem that different kinds of intelligence home terminals bring the great difference of network interface, the RF communication module which controls appliances through four-wire was designed. The interface of module is concise and highly compatible. First of all, the architecture of intelligence home which based on RF wireless communication technology was described. A wireless communication module using STM8S103F3 microcontroller and CC1101 wireless transceiver was designed. In addition, the hardware and software design of the communication module was discussed. Simulated FIFO buffer is used to ensure no loss of data while anti-collision function is realized by checking the frequency of electromagnetic wave before sending data. Test results show that this module can meet the demand of low cost, low power consumption and long distance wireless transmission.
