针对无线多媒体传感器网络广泛的应用前景和目前节点平台稀缺的情况,设计并研制了一种小型化的无线多媒体传感器网络节点。节点采用ADI公司的ADSP-BF561微处理器和Helicomm公司的基于Zigbee网络协议的无线收发模块IP-Link研制而成。在输入通道上可分别支持模拟图像传感器和数字图像传感器。输出通道具有多媒体传输通道和数据/命令传输通道,其中多媒体传输通道用于传输实时的模拟视频,数据/命令传输通道用于传输节点处理之后的有效数据以及接收来自上层网络的命令。 Aiming at the wide application prospect of wireless multimedia sensor network and the current shortage of node platform, a miniaturized wireless multimedia sensor network node is designed and developed. The node is developed by ADI’s ADSP-BF561 microprocessor and Helicomm’s IP-Link wireless transceiver module based on Zigbee network protocol. The input channel supports analog image sensors and digital image sensors respectively. The output channel has a multimedia transmission channel for transmitting real-time analog video, a data / command transmission channel for transmitting valid data processed by the node, and a command for receiving the data from the upper network, and a data / command transmission channel.
