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 realize low cost remote image monitoring, a set of remote image acquisition and transmission system based on ZigBee and GPRS technology is designed. CC2430 as a node to control the camera to capture image data, local communication, the image data through the ZigBee coordinator and server communication directly; remote communication, the coordinator will process the data through the GPRS technology to monitor the center in order to achieve the preservation of image data, Read and display purposes. ZigBee wireless sensor network nodes using mesh network ad hoc network mode, by modifying the protocol stack buffer mechanism and change the serial port baud rate to improve data transmission efficiency. The experimental results show that the system can capture and transmit local and remote still images well and has a wide range of applications.
