摘　　要：γ射线监视器(Gamma Ray Monitor,GRM)是计划于2021年发射运行的中法合作太空望远镜项目——天基多波段空间变源监视器(Space Variable Objects Monitor,SVOM)的4个载荷之一。GRM的数据管理模块采用基于AT7910芯片的Space Wire总线对数据进行收发,数据率为100 Mbit·s^(-1)。通过构建组路由(Group Adaptive Routing,GAR)判断主备机状态并选择数据发送通道,进而完成载荷和平台之间的信息传输。测试结果表明:利用Space Wire总线可以实现数据管理模块与卫星平台之间数据的交互。[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 Space Wire 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 Space Wire bus to realize the data exchange with the satellite platform.
