摘要
该文提出了基于ZigBee网络的多跳图像传输系统的设计，该系统由三部分组成，即图像采集模块，路由传输模块和图像接收模块。CMOS摄像头和CC2420片上系统构成了图像传输系统的采集节点，利用Mesh型网络的自组织和自愈功能，该系统允许多节点采集，并且远端的节点信息可以通过“多跳”的方式到达终端设备。此外，该多跳图像传输系统具有设计简单、易于安装、低价格、低功耗的特点，使得它可以在很多领域得到广泛应用。
In this paper, a wireless image transmission system based on ZigBee network has been proposed. The system consists of three parts, namely image acquisition module, routing transmission module and image receiving module. The CMOS camera OV2640 and CC2420 wireless SoC chip constitute the image acquisition node. With the help of the Self-organizing and Self-healing functions that mesh network has, this dynamical network allows multi-node capture. As all the nodes form a mesh structure, information on the remote node can finally reach the terminal via muhi-hop. Furthermore, the characteristics of simple structure, easy installation, low cost and low power for the designed system will make it be widely applied in many fields.
