摘要
本文主要介绍了无线传感器网络节点的分析和设计。系统选用了低功耗的MSP430系列单片机作为控制器,同时选用了低功耗的射频通信芯片NRF2401。软件部分设计了一种突发通信模式,利用NRF2401提供的Shock Burst通信模式进行数据通信。同时系统程序部分充分利用MSP430系列单片机提供的低功耗模式以降低系统的总功耗,此外本文就各模块芯片的通信协议以及对应的程序也进行了具体的分析。
The main purpose of this paper is to introduce the analysis and design of a node in wireless sensor network. This system is composed of the low-power MCU of MSP430 ＆ NRF2401 used for RF communication. The software is the Shockburst mode of communication provided by the NRF2401, which is chosen to complete the communications in the system. At the same time, the sleeping modes provided by the MCU are fully utilized to reduce the system＇s power consumption. In addition, the communication protocol and the program of the chips are also analyzed.
