摘要
利用ZigBee无线传感器网络,应用FPGA器件对采集到的图像进行压缩,使用多路ZigBee模块进行无线网络并行数据传输,实现图像的非实时无线采集。利用了ZigBee技术的多信道特点和FPGA所具有的灵活性以及其在数字信号处理方面的优势,在一定程度上解决ZigBee网络低传输速率与图像要求的高传输速率之间的矛盾,缩短了无线图像传输的时间,使得ZigBee技术在图像传输方面具有更大的实用性。该系统可以应用于对实时性要求不高,同时具有多节点的监控场合。
This article introduced the realization of non-real-time wireless image acquisition based on ZigBee wireless sensor networks, applying FPGA device to image compression and using multi-use ZigBee wireless network module to parallelly transmit the data. Using ZigBee technology, the characteristics of multi-channel parallel transmission of data and the flexibility of FPGA and digital signal processing advantages, it can solve the ZigBee network contradiction be- tween low transmission rate and image requirements of high transmission speed ,and shorten the use of ZigBee wireless image transmission time. It makes ZigBee in the video transmission in this regard with more practicality. The system can be applied in multi-node monitoring occasions where do not need high real-time.
