Design and Implementation of Xinjiang Astronomical Observatory Astronomical Data Transmission Visualization System

الملخص EN

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.
