Description

technical field [0001] The invention relates to a simulation and verification platform for a spaceborne information system. Background technique [0002] The traditional space-borne information system uses the data bus network as the information transmission center. Through the data bus network, distributed data collection and command output, centralized calculation and control are realized, thereby improving the efficiency of system processing. In the bus network, the data exchange between devices is realized through the data bus. Generally, the bus master-slave response mode is adopted to transmit platform instruction data and telemetry acquisition data, which meets the key and high reliability data transmission task requirements for platform measurement and control. . In the data exchange process of the bus, the BC terminal device always acts as the controller of the bus (BC) and initiates the communication of the bus; the RT terminal device, under the excitation and tri...

Problems solved by technology

[0003] The traditional design and test method generally obtains various indicators of the bus through the calculation method of the designer, and obtains whether it can meet the requirements of satellite performance indicators. The above-mentioned traditional design and test method mainly has the following three problems: 1. Can analyze a small amount of terminal equipment; 2. Cannot automatically complete the simulation analysis work; 3. The test and verification work is severely limited by the development progress of the hardware

[0004] In addition, the complexity of the current space-borne information system has been greatly increased, with a wide variety of information, a large number of information nodes, and a complex information network topology. It has difficulties in the analysis process and large differences in verification test objects. Therefore, traditional design and test methods can no longer Satisfied with the new generation of spaceborne information system, it is impossible to carry out effective and comprehensive simulation verification of spaceborne information
