摘要
为实现低成本远程图像监控,文章设计了一套基于ZigBee和GPRS技术的远程图像采集传输系统。以CC2430为节点控制摄像头采集图像数据,本地通信时,图像数据通过ZigBee协调器直接和服务器通信;远程通信时,协调器将处理好的数据通过GPRS技术传到监控中心以实现图像数据的保存、读取和显示等目的。ZigBee无线传感网络节点间采用网状网络的自组网方式,通过修改协议栈的缓冲机制和改变串口波特率提高数据的传输效率。实验结果表明该系统能够很好地实现本地和远程静态图像的采集与快速传输,具有广泛的应用前景。
In order to achieve low-cost image monitoring, an image acquisition system based on ZigBee and GPRS technologies is designed and implemented. The CC2430 is used as node to control camera to acquire image, data are received and sent to the server through the ZigBee coordinator in local communication. The processed data are Sent by coordinator to monitoring center via GPRS to realize saving, reading, and display of the image data in remote communication. Mesh network mode is used in ZigBee network in the system, and the transmission efficiency of the data is enhanced through modifying the buffer mechanism of the protocol stack and changing the baud rate of the serial port. Experimental results show the system can well realize the acquisition and fast transmission of the local image and static remote image, and thus will have broad application prospects.
