摘　　要：针对LAMOST(郭守敬望远镜)观测信息与结果分析的实时性需求,提出在Android移动平台实现观测信息集成系统的方案。瘦客户端模式被应用到系统的开发中,即在服务器端对海量数据进行处理和分析,其结果在Android客户端中进行数据可视化。首先介绍了Android的架构和望远镜的观测需求,然后详细阐述了系统的整体架构和功能模块。通过HTTP通信、多线程异步访问、HTML5技术、Achart Engine开源图表类库、JSON数据格式等关键技术,设计并实现了Android上用于辅助望远镜观测的信息集成系统。最后在实际设备中通过典型操作实例测试分析了系统运行状态,验证了其可行性与有效性。该系统目前已应用在天文观测的多个方面。A novel subsidiary system on Android to meet various requirements of LAMOST（ Large Sky Area Multi-Object Fiber Spectroscopic Telescope） was proposed, including real-time on-line inspection of observation plans and analyzation of the observed ones. This system adopted a thin client model（ i. e. data processing on the server and data visualization on the client）. Firstly a brief introduction of the architecture of Android operationg system and the observation requirements of LAMOST were given. Then, the system architecture and functional modules were analyzed in details. After that, some key technologies in the system were discussed（ e. g. the communication of HTTP method, multi-thread asynchronous access,HTML5, Achart Engine open source library, JSON data format）. Finally, it was tested in virtual machine and real smart mobile phones in order to verify its feasibility and effectiveness. The system has been used in astronomical observation in many aspects.
