Abstract: [Background] The gamma ray monitor (GRM) is one of the four payloads of the space variable objects monitor (SVOM) scheduled to be launched in 2021. [Purpose] This study aims to design data management module of GRM for data interaction with SVOM. [Methods] The SpaceWire bus architecture based on the AT7910 chip is adopted to complete data transmission at the data transfer rate of 100 Mbit·s-1. Channel identification is achieved by the construction of group adaptive routing (GAR) to determine the status of the hot and cold spare device, and select the data transmission channel to complete the information transmission between GRM and SVOM. [Results & Conclusion] The test results show that GRM data management module can utilize the SpaceWire bus to realize the data exchange with the satellite platform.
