基于视频网络服务多通道数据采集系统的研究与设计

Research and Design of Multi-channel Data Acquisition System based on Video Network Services

现有水文遥测终端无法实现包括视频信号在内的多通道数据采集,传统的视频网络监控也不能很好满足水利水文行业的遥测需求,通过利用信息融合技术,提出一种基于嵌入式ARM系统的水利水文多通道数据采集控制方案。该多通道系统终端软件部分采用嵌入式Linux系统编程,硬件部分控制多通道信息的采集。实验结果表明,该系统终端采集通道具有很强可扩展性,并且实现基于嵌入式终端的视频图像、图片采集,具有很好的技术先进性和良好的应用前景。

Existing hydrological RTU can not achieve multi-channel data acquisition including video signals. And traditional video network monitoring can not meet to telemetry demand of water conservancy hydrological industry. Through the use of information fusion technology, the article proposes the multi-channel data acquisition scheme of water conservancy and hydrological based on embedded ARM system. The software part of the system uses embedded Linux programming. And the hardware part is used to control multi-channel information collection. The experiment results show that terminal acquisition channels of the system have strong expansion and can realize collecting of video image and pictures. It has well technical advancement and good application prosect.
