一种基于RSSI自适应的双模通信模块设计与实现

Design and Realization of an Adaptive Dual-mode Communication Module Based on RSSI

无线通信与电力线通信各具特色,在智能电网中具有广泛的应用前景,二者协作可以优势互补,提高用电信息采集系统的综合性能。针对无线通信与电力线通信混合组网技术,提出了一种基于接收信号强度(RSSI)的自适应信道选择算法,可以依据链路质量自适应选择通信方式;研究了双模通信模块的软硬件设计并进行实际测试。测试结果显示,自适应双模通信的成功率高于单一的通信方式,通信的灵活性与可靠性进一步提高。

Wireless communication and the power line communication are distinctive and have extensive application prospect in the smart grid. The cooperative communications can complement each advantages,and improve the comprehensive properties of electricity information acquisition system. This paper uses the power line communication and the wireless communication hybrid networking technology,proposes an adaptive channel selection algorithm based on Received Signal Strength Indication( RSSI),which can adaptively choose communication mode according to the link quality; The dual-mode communication module design of software and hardware is studied. In the end,the double module was tested. The results show that the success rate of adaptive dual mode communication is higher than that the single communication mode,which means the flexibility and reliability of communication are further increased.
