基于 ZigBee 的图像传输系统设计与实现

摘要

设计并实现了基于 ZigBee 无线传感器网络的图像采集及传输系统.该系统由 WinCE 系统的图像采集节点、路由节点与汇聚节点构成，图像传输采用数据分组思想，提出多串口多路径并行通信的图像传输数据协议，使得传感器网络能量负载均衡，具有较好实时性，并在 ZigBee 协议下实现 CC2530与 CC2430模块混合通信传输视频图像；上位机采用 VC＋＋6．0编程显示节点网络拓扑图和接收到的图像.实验结果表明，该系统成本低，安全性高，能很好地实现图像传输.%The paper designed and implemented the image collection and transmission system based on wireless sensor network (WSN),in which The USB camera of the ARM board with Wince system collects and transmits images;under different versions ZigBee agreement mixed with CC2530 and CC2430 module communication transmission of video images;PC using VC++ 6.0 programming display nodes network topology and the receive image.The experiment results show that the system is of low cost and high safety, and capable of good image transmission.
