Description

Technical Field

[0001] This invention relates to the field of airborne system ground testing technology, specifically to a multi-system ground joint testing platform and method based on a test management center. Background Technology

[0002] Modern high-tech conditions place higher demands on aircraft performance and the integrated design of airborne systems, leading to increasingly complex inter-system coupling. In fact, high-intensity training missions involve frequent use of airborne systems and a high probability of failure. However, the failure of aircraft functions caused by inter-system coupling is often difficult to locate and reproduce. Furthermore, some training scenarios involving different aircraft types cannot be simulated on the ground, resulting in insufficient verification of certain combat performance characteristics. Therefore, to better improve the quality assurance of airborne products for training missions, fully realizing ground verification of cross-system inter-system functions is particularly important.

[0003] Patent [CN201810333855.4] discloses an integrated verification system for integrated avionics equipment, suitable for integrated verification of the functions and performance of various integrated avionics equipment; Patent [CN201811023551.4] discloses a large aircraft electromechanical system integrated test platform, capable of realizing functional excitation and status monitoring of airborne equipment of electromechanical systems, and realizing comprehensive analysis of electromechanical system bus parameters and human-machine interaction; Patent [CN201911365919.X] discloses an on-board test of flight control system. The platform and its methods can realize closed-loop testing of flight control systems, etc. The disadvantage of the above patents is that the object is a single system, and the internal functions of the system are tested or verified on the ground. Patent [CN201810940258.8] discloses a ground integrated debugging and verification platform for avionics and flight control systems, which can realize independent functional testing and partial cross-functional testing of airborne avionics and flight control systems. However, its disadvantage is that it does not have the function of actual combat simulation, and cannot meet the ground verification needs of complex battlefield environments such as overall aircraft performance evaluation and system confrontation under the trend of future joint missions.

[0004] Furthermore, for geographically dispersed and management-segmented test platforms of different subsystems, the simulation equipment and excitation equipment configured within them cannot be fully shared, resulting in a certain degree of resource waste. Summary of the Invention
