农业双向视频诊断系统的设计与研究

农业信息化服务是实现中国农业现代化的重要手段。随着基于3G的多路音频视频传输技术的逐渐成长、完善，迫切需要满足农业技术交流的音视频通信工具和远程专家诊断系统。笔者利用开源的Open Meetings系统进行设计和二次开发，实现了农户、农技员与专家之间的远程视频交流，并将该系统应用于全国基层农技推广信息化平台，为服务三农及农业信息化提供了有力的支持。系统实施后的实际的效果表明，该系统有效地促进了新技术的推广和信息资源的整合。

Design and Research on Agricultural Two-way Video Diagnosis System

Agricultural informatization is the important method to realize agricultural modernization for China. With the development of multi-way audio-visual transfer technology based on 3G, people urgently needs the audio-visual communication tool and remote professional diagnosis system. The author used open-source system Open Meetings to design and secondary develop, and realized remote video communication among agricultural users, agricultural technicians and agricultural professors. This system had been integrated in agricultural technology extension informatization platform, and supported serving agriculture, rural areas and peasant and agricultural informatization. The actual results showed that: the system has effectively promoted agricultural technology extension and information resources integration after the system deployment.
