摘　　要：卫星互联网作为国家新型基础设施建设的重要组成部分,在国家战略、技术发展以及产业需求的多重驱动下,发展迅速。星载交换技术决定着空间网络的容量和组网能力,是实现全域覆盖卫星互联网的关键。针对大容量星载交换设备在轨维修难度大且价格昂贵的问题,设计了面向多接口、大容量星载交换设备的地面检测系统;基于现场可编程门阵列(Field Programmable Gate Array,FPGA)完成了地面检测系统的软硬件开发,实现了地面检测系统的测试和大容量星载交换设备的在地功能测试,保障了星载设备在轨的正常运行。As an important part of new national infrastructure construction,satellite Internet has developed rapidly under the multiple drives of national strategy,technological development and industrial demand.Space-borne switching technology determines the capacity and networking capabilities of space networks,and is the key to realizing full-area coverage of satellite Internet.Aiming at the difficult and expensive on-orbit maintenance of large-capacity spaceborne switching equipment,a ground detection system for multi-interface,large-capacity spaceborne switching equipment was designed.The software and hardware development of the ground detection system was completed based on FPGA.The test of the ground detection system and the on-site function test of the large-capacity space-borne switching equipment ensure normal operation of the space-borne equipment in orbit.
