Design of Equivalent Simulation Test System for Universal Power Supply and Distribution of Space Station Multi-aircraft

Abstract

AbstractIn the process of system-level test and verification of manned spacecraft, traditional power supply and distribution interface test and verification usually use a dedicated equivalent simulation system for special aircraft. The system state is solidified, the simulation method is single, the function is simple, and it cannot be adapted to the subsequent multi-model and extended functions verification. Aiming at the needs of power supply and distribution interface test verification in the current multi-cabin and multi-aircraft system-level test process of space station engineering, a universal, multi-spectrum-supported, and expandable multi-aircraft power supply and distribution equivalent simulation test system is proposed. The system adopts a modular design, combined with a reconfigurable software system, and deeply integrates software and hardware. Through a reconfigurable design, it has the ability to support the interface verification between multiple different aircraft, and it can quickly perform the new research aircraft on the ground. Effective verification. Established a general-purpose module combining software and hardware, with more comprehensive coverage (signal, power, step), higher automation, more detailed data recording, and verified by model testing, the system can quickly realize the interface with multiple types of manned spacecraft Simulation verification improves the parallelism of test and development, covers more failure modes, the system structure is reliable, and the cost is significantly reduced.KeywordsSpace stationGeneral purposeEquivalent simulation
