基于MSP430的低功耗近距无线图像传输系统设计与实现

Design and Implementation of Short Distance Wireless Image Transmission System of Low Power Consumption Based on MSP430

近距无线图像传输系统主要用于无线传感器网络中的图像采集、传输、处理和显示，本文设计并实现了一种具有较强实用性的近距无线图像传输系统。采用OV7670图像传感器作为图像数据采集器，高速低功耗的nRF24L01射频模块作为无线收发器，采用MSP430F14916位超低功耗单片机作为微处理器，所构成的系统具有功耗低、图像传输速度快等优点。作者详细阐述了该系统的硬件结构和软件设计。

The short-range wireless image transmission system is mainly used for image collecting, transmitting, processing and tisplaying in the wireless sensor networks, a short-range wireless image transmission system which has strong practical applicability s designed in this paper. By adopting the imaging sensor OV7670 as the image data acquisition unit, the high speed and low power RF module nRF24L01as the wireless transceiver and the 16bit ultra-low-power MCU MSP430F149 as the microprocessor, the con- tituent system is of the advantages of low power consumption and fast image transmission speed, etc. The authors elaborate the hard- ware structure and software design of the svstem.
