基于 nRF24L01的无线水声信号传输

摘要

Characteristics and pin functions of RF chip nRF24L01 and ultra low power master control chip MSP430F1611 MCU are introduced. Based on the design requirements, hardware and software for wireless under-water acoustic signal transmission system are designed, which include: hardware schematics of the wireless trans-mission system consisting of nRF24L01 and MSP430F1611; software control process for setting the nRF24L01 to work in sleep to wakeup mode for purpose of low power consumption. In application experiments of the wireless transmission systems, underwater acoustic signal data received is sent to a host computer, data simulation and graphics processing are performed by using Matlab software.%本文介绍了射频芯片 nRF24L01和主控芯片超低功耗系列单片机 MSP430F1611的芯片特点与引脚功能；根据设计要求对无线水声信号传输系统进行硬件和软件设计：设计了 nRF24L01和MSP430F1611组成的无线传输系统硬件原理图，并以实现低功耗为目的，将 nRF24L01设定为先睡眠后唤醒的工作方式的软件控制过程。将无线传输系统运用到实验中，把实验采集到的水声信号数据传输到上位机，通过 Matlab 软件对数据进行仿真并对图形进行相应的处理。
