摘要
针对野生动物图像采集中存在的监测周期长、人工成本高等不足,设计了一个基于无线传感器网络的图像监测系统。该系统使用红外传感器感应野生动物,利用图像传感器采集图像,并通过低功耗的无线传感器网络将图像传输至协调节点,再利用4G网络上传至服务器。文中对系统的硬件平台及软件程序进行设计,并在ZigBee协议的基础上增加应答协议,提高了图像传输成功率。测试结果表明,两个节点之间距离在170m以内时,传输成功率能达到90%以上,且整个系统能通过多跳方式拓宽监测区域。
In order to surmount drawbacks like long monitor yclicity and high labor costs which exiting in the wildlifes＊ mage acquisition, a kind of image monitoring system based on wireless sensor networks was designed. The system senses wildlife y passive infrared sensor and uses image sensors to acquire nimals’ image. The image was transmitted to coordinate node hrough the low consumption wireless sensor network and then hem were uploaded into server by 4G network. In this paper, the ardware platform and software was designed, and to improve the uccess rate of image transmission a response protocol based on he ZigBee protocol was implemented. The test results showed that he distance between two nodes within 170m, the transmission ate could reach over than 90% and the monitoring system could roaden the monitoring area by the way of multiple-hop.
