Abstract

With the development of astronomical observation technology, astronomical devices produce more data than ever. Astronomical telescopes are usually far away from city, so the long-distance data transmission between telescope and data center faces great challenges. Visualization system of astronomical data transmission with four-layer structure was built to manage data transmission. This visualization system has a four-layer structure: hardware layer, system layer, middle layer, and visualization layer. System function includes automatic data transmission, log recording of transmission process, and display of the transmission status in dynamic web pages. Besides, the middle layer contains an alarm subsystem that can automatically send system exceptions to administrator. We also design corresponding mechanisms to ensure the high stability of the system and to control the data transmission when the network is unstable through adaptive algorithms. In test, this visualization system can run stably for a long time in unmanned manner. This system also provides a solution for the astronomical observation bases to automatically transmit data to the data center.

新疆天文台天文数据传输可视化系统的设计与实现

随着天文观测技术的发展，天文设备产生的数据比以往任何时候都要多。天文望远镜通常离城市较远，因此望远镜与数据中心之间的远距离数据传输面临着很大的挑战。建立了四层结构的天文数据传输可视化系统，对数据传输进行管理。该可视化系统具有四层结构:硬件层、系统层、中间层和可视化层。系统功能包括数据自动传输、传输过程日志记录、动态网页显示传输状态等。此外，中间层还包含一个告警子系统，可以自动将系统异常发送给管理员。我们还设计了相应的机制来保证系统的高稳定性，并通过自适应算法控制网络不稳定时的数据传输。经测试，该可视化系统能在无人状态下长时间稳定运行。该系统还为天文观测基地自动向数据中心传输数据提供了解决方案。
