摘　　要：卫星批量化生产过程中会实时生成各类海量遥测数据,如何将海量遥测数据实时准确地发送至所需位置是保证卫星状态受控的首要前提.针对卫星海量数据实时推送的问题,设计了基于SignalR的卫星遥测数据实时推送系统并完成了验证.该系统采用消息队列+SignalR的模式,可实现测试数据实时推送到各个终端软件.它能够满足百颗星量级同时测试时产生数据的实时推送,并支持各个终端软件订阅不同卫星的不同类型的遥测测试数据.该系统已应用于某批量化生产卫星,可将多颗卫星的实时遥测数据同时推送至1台或多台终端,完成了1人测试并监测1颗卫星模式向1人测试并监测多颗卫星模式的转变,且能够实时动态切换不同卫星遥测数据状态,可支持卫星批量化生产模式.During the batch production of satellites,various kinds of massive telemetry data are generated in real time.How to send the massive telemetry data to the required location timely and accurately is the primary premise to ensure the satellite state control.To deal with the problem of real-time push of massive satellite data,the real-time push system of satellite telemetry data based on SignalR was designed and verified.The system adopted the mode of message queue+SignalR to push the test data to each terminal software in real time.It could meet the real-time push of the data generated by the simultaneous test of hundreds of satellites and support the subscription of different types of telemetry test data from different satellites by various terminal software.The system has been applied to the batch production of satellites,which can push real-time telemetry data from multiple satellites to one or more terminals at the same time.The mode of one person to one satellite for testing and monitoring has been transformed to that of one person to multiple satellites,and the status of telemetry data of different satellites is dynamically switched in real time.The application of this system shows that it can support satellite batch production mode.
