基于nRF24L01芯片的图像无线传输系统设计

摘要

In view of the advantages of the wireless data transmission, a wireless image data transmission system used in short distance is designed in this paper. The system selects MT9M001 image sensor as the data acquisition unit at the sending end, and uses DSP as the control unit at both ends of the system. The image data is then transmitted by nRF24L01 radio frequency chip between the two ends. The result of outdoor test shows that the system designed in this paper has high reliability when a gray image with a resolution of 640×512 is transmitted, under the condition of occlusion.%鉴于无线数据传输方式的一些优点,设计了一套用于短距离的无线图像数据传输系统.该系统选用MT9M001图像传感器作为发送端的数据采集单元,以DSP作为收、发两端的控制单元,利用nRF24L01射频芯片完成图像数据在收发端的传输.在室外20 m有遮挡环境下的测试表明:该系统发送并接收分辨率为640×512的灰度图像时具有很高的可靠性.
