无线多媒体传感器网络中相机节点的设计与实现

Design and implementation of camera sensor node in wireless multimedia sensor networks

相机节点是组建无线多媒体传感器网络(WMSNs)的核心部分。提出了一种基于TMS320C6204的低功耗、低成本、中等图像传输质量的WMSNs相机节点设计方案,完成了相应的硬件电路设计,介绍了其工作原理、系统流程,详细说明了DSP与图像传感器、DSP与无线收发模块之间的接口方法,并基于波特率、图像压缩进行了定量分析。

The camera node is the pivotal section for building the wireless multimedia sensor networks. A design of wireless multimedia sensor node which has low power, low cost and middle image delivery based on TMS320C6204 is presented. The circuit design of hardware is realized, and its working principle, system technological process ard introduced. The interface between image sensor and DSP, wireless module and DSP is expressed, and the design data based on Baud rate and arithmetic of compressing is analysed.
