Abstract:

[Objective] Required by the strategic deployment of Purple Mountain Observatory’s “The 13th Five-Year Plan” based on the on-orbit operation and scientific research of DArk Matter Particle Explorer (DAMPE), the goal of the application is to build a characteristic data resource system and a uniform application service platform to support the scientific research activities of DAMPE. [Methods] Through the combination of DAMPE system data resources and a unified information architecture design and deployment, a highly integrated information application system is established. The system comprises of a multi-point synchronous gamma data release platform that integrates retrieval and encapsulation, a scientific research achievement approval system that reviews the full cycle of resources, and a data analysis software for photon selection, statistical analysis and observation simulation of multiple targets. [Results] The information application system of DAMPE is implemented, which achieves resource aggregation management, applications integration, and operation and maintenance services for technological innovation and continuous development supports. In the near future, a resource sharing service based on the data cloud service environment of CAS will be provided.
