针对目前田间监测主要是物理数据而缺少多媒体数据的问题,设计一种基于无线多媒体传感器网络(WMSN)的作物环境与长势远程监测系统.阐述了该系统存在的显著优势；设计了Hi3512和CC2430硬件电路关键部分和软件系统,解决了作物环境信息与多媒体长势信息融合的关键问题；实现了4间温室内不同监测点温湿度、光照度及4路视频信号的动态监测.实验结果表明,该作物环境与长势远程监控系统稳定可靠,实时精确,能实现多媒体数据采集、H.264压缩、3G传输、PC显示和温湿度、光照度传感器节点的ZigBee组网.%The current field monitoring is mainly physical data and lack of multimedia data. A remote monitoring system of crop environment and growing was designed based on WMSN. Firstly, the advantages of the proposed system were analyzed. Then, the key parts of the hardware circuit of Hi3512 and CC2430 and software systems were designed. The key issues of fusion of the crop physical environment and multimedia growing information were resolved. Finally, the temperature and humidity, light intensity, and four-channel video signal in different monitoring points in the four greenhouses were monitored dynamically. The results show that the environment of the crop growing remote monitoring system is stable and accurate. Multimedia data acquisition, H.264 compression, 3G transmission, display on PC could be achieved, together with ZigBee networking including temperature, humidity and light intensity sensor nodes.
