Abstract
Spacecraft is generally a complex system, which could produce a large amount of test data during the integrated testing process. The existing data management system for spacecraft integrated testing has the following disadvantages: the management of test data is not efficient; the existing traditional data management mode is not conducive to the query and management of historical model data; the security and reliability of data management is not high. In order to manage and maintain these test data more, according to the actual situation of spacecraft test and the particularity of data, a distributed file system of data management system for spacecraft integrated test is designed and implemented in the paper. It mainly includes: the data organization management form of the distributed file system, the allocation of storage space, the mechanism of file backup, the error correction scheme after data error, and the management scheme of hot and cold data.
