摘　　要：为了监测和跟踪监控区域内的目标对象,提出了一种基于无线传感器网络节点的设计方案。随着高清图像传输速度越来越快、存储容量不断增大,使得每个节点的数据存储速率成为关键。以FPGA、DSP为控制核心,利用双片选交替双平面技术对混合编帧后的数据进行存储,实现了一种对图像的高速采集,并解决了数据存储速率的问题。通过对系统采集回的数据进行科学分析和图像还原,结果表明该设计能够可靠、有效地实现对图像信息的采集与存储。In order to monitor and track the target object within the monitored area, a design scheme was proposed based on wireless sensor network nodes. With high-definition image transmission faster and faster, the storage ca- pacity is increasing, so that the data storage rate of each node becomes the key. Based on FPGA, DSP as the control center, using two dual-plane technique chips select alternate data after mixing framing store implements a high- speed image capture and solves the problem of data storage rate. Through scientific analysis data of the system col- lecting and image reproduction, the results show that the design can be reliably and effectively realize the image in- formation acquisition and storage.
