基于FPGA的WSNs低功耗节点设计与实现

摘要

基于FPGA结构灵活、可编程性强,具有强大的并行数据处理能力等优点,采用低功耗的Zig Bee技术对无线传感器网络( WSNs)节点进行软硬件设计.植入Nios系统和相关的IP核到芯片EP1C12Q240C8中,协同具有多种工作模式的CC1100射频芯片,实现节点的功能,并进行了功耗测试及比较.结果表明:节点功耗低,具有良好的可扩展性和移植性,达到了WSNs节点设计的要求,可用于工业生产.%Based on the characteristics of flexible structure, strong programmability and parallel data processing capability of FPGA platform,the hardware and software of WSNs node by using low power consumption Zig Bee technology are designed. Nios systems and related IP core are embedded to the chip EP1C12Q240C8 in collaboration with a variety of operating modes of the CC1100 RF chip to realize the function of the node. Node power consumption testing and comparison are made. The results show that the node can supply the design demand of WSNs and it also has low power consumption, expansibility and portability, which can be used for industrial production.
