摘要
为克服射频信息空间耦合传输的隐蔽性问题,实现RFID技术的可视化,设计了一种集成RFID信息的无线图像传输系统;以S3C2440A处理器为核心,搭载USB摄像头和WIFI模块,在嵌入式Linux系统下编写和加载nRF2401模块设备驱动程序,以射频信息触发USB摄像头抓拍,融合RFID和图像信息,通过WIFI模块无线上传至远端主机;实验中将RFID标签置于移动小车上来模拟运动目标,结果表明系统对于移动中的物体有很好的识别和拍摄效果,图像传输速度快,在现代物流和道路交通监测等行业有很好的应用前景。
A wireless image transmission system integrated RFID information was designed to overcome the concealment of radio frequen- cy information in space coupling transmission, realized RFID technology visualization. S3C2440A processor was selected as the core, WIFI module and USB camera were equipped in the system. The driver program of nRF2401 module was designed and transplanted into Embedded Linux. The USB camera was triggered to capture the image by RFID information for achieving integration of RFID and video. The integrated images would be wirelessly uploaded to the remote computer by WIFI module. The RFID tag was assembled in small car which simulated moving target. Experiments show the system is good at capturing and recognition moving object, the image transmission is fast. The system has a good application prospect in the modern logistics and road traffic monitoring and other industries.
