Abstract: Since the operation of the steady high magnetic field large- scale scientific facility, the continuous increase in machine hours has posed challenges to the management of device data. In this paper, a steady- state strong magnetic field data management system is designed and developed. The system automatically parsed device data into the Elasticsearch database, providing users with integrated services such as data archiving, querying, downloading, and data visualization. Additionally, this paper proposed a data compression method that significantly reduces data volume to meet the large- scale compression application requirements of device data.
