Abstract

The invention discloses a radio astronomy data storage consistency guarantee method, device, system and storage medium. The method includes: receiving radio astronomy data of a digital receiver and connecting to a Zookeeper server; obtaining available metadata through a load balancing module server and data server; according to the filled UVFITS header information, obtain a globally unique ID through Zookeeper; send the ID together with the UVFITS header information to the metadata server and data server; configure the node according to the status of the metadata server and the status of the data server ID value, judge whether it is the UVFITS header information and data segment of unified data, and mark it; if it is judged that it is not the UVFITS header information and data segment of unified data, perform corresponding processing according to the marking result. The invention can solve the consistency problem of radio astronomical data metadata, original data and processed data, and provide basic support for upper layer application services of various radio observation application systems.

Description

technical field [0001] The invention relates to a method, device, system and storage medium for ensuring the consistency of radio astronomical data storage, and belongs to the technical fields of astronomical technology and computer application. Background technique [0002] Radio astronomy is an important research field in astronomy. Large-scale radio telescopes were first established at home and abroad, such as the "Sky Eye" 500-meter-aperture radio telescope (FAST) in Guizhou, my country, and the centimeter-decimeter wave radioheliograph in Ming'antu, Inner Mongolia. (MUSER), foreign radio telescopes such as the Canadian Hydrogen Intensity Mapping Experiment (CHIME) cylindrical antenna; the Jansky Very Large Array (VLA) in the United States. These radio telescopes can measure physical quantities such as the intensity, frequency spectrum and polarization of celestial radio. In recent years, with the development of information technology, many observation equipment with hig...
