摘要
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。
A miniaturized wireless multimedia sensor network node （WMSN） is proposed,while wireless multimedia sensor network has wide application prospect and prior art is lack in node platform. The node adopts one ADSP-BF561 of ADI and one wireless transceiver IP-Link which is produced by Helicomm and based on Zigbee network protocol. The input channel of the node is adaptable to analogue image sensor and digital image sensor,and the output channel includes a multimedia transmission channel and a data/command transmission channel,wherein the multimedia transmission channel can transmit real-time analogue video,and the data/command transmission channel can transmit effective data processed by the node and receive the command of upper network.
