Design And Implementation Of Domestic High Reliability Measurement And Control Computer System

At present, the number of users and data capacity of space TT&C missions are increasing, which puts forward higher requirements for the reliability of computer systems and autonomous and controllable security. Aiming at the information processing application and command management needs of space missions under the new situation, the architecture design of aerospace measurement and control computer system with domestic hardware and independent controllable basic software as the core is proposed. It solves the problems of dual-route customized transmission, dual-network multicast sharding coverage of the same channel, secure sharing of real-time files, accurate synchronization of homologous multiple signals in the high-stream video lossless compression display control system under IP network, and multi-source signal fusion, etc. The design and integrated implementation of this computer system plays a major role in the field of manned spaceflight measurement and control, satellite launch technology for high real-time, high reliability, high scalability and high security of the central business system.
