The implementation of a complete set of cockpit display system prototype verification platform of the present invention adopts componentization and modular design to realize the rapid construction and reconstruction of the cockpit display system prototype verification platform. The hardware equipment adopts shelf-type products combined with the designed platform The stand can adjust the position and angle of the hardware equipment, and the shelf-type products do not need to be customized, which greatly reduces the proportion of customized equipment, reduces the implementation cycle and implementation cost of the entire platform, and ensures the realism of the prototype of the cockpit display system. , and because of its good adaptability and scalability, it still has good versatility and high reusability for the transformation or upgrade of similar models.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a simulation platform for prototype verification of aircraft cockpit display system design. Background technique [0002] At present, in the early prototype design and development process of the cockpit display system, it is usually necessary to build a cockpit display system prototype platform according to the design to simulate various displays, instruments, switch control panels, control devices, etc. in the aircraft cockpit It is convenient for experts in various fields and flight test pilots to review and demonstrate the rationality of the structural design, layout design, display content, and man-machine operation of the cockpit display system in the early prototype design stage of the aircraft. During the entire early prototyping and R&D process, multiple rounds of iterative design, prototype demonstration, and demonstration revision are often required. Each round of d...

Problems solved by technology

The pure physical simulation verification platform is to build all the components of the designed cockpit display system according to the full function and performance requirements of the actual installation parts. The prototype verification platform built by these two implementation methods is realistic and has a high degree of simulation. However, in the early prototype design of the cockpit display system, there may be frequent requirements and design changes. Large changes may occur. If these two implementation forms are used, the structure and software and hardware platforms need to be re-customized for each design version. The cost is very high, the implementation cycle is also very long, and the cost of iterative design is huge.

And because the software and hardware of the cockpit display system of each model are quite different, the reusability and expandability of the software and hardware of the pure physical object and semi-physical simulation platform are quite limited.

The pure software simulation verification platform is mainly designed for the simulation design of the main flight display area of ​​the cockpit display system. Although it realizes the decoupling from the hardware with high cost, it cannot control the structural layout of the cockpit display system, instruments, switch control panels, The simulation of the control device is very low in fidelity, which cannot bring good verification and demonstration effects; and the design and implementation of the main flight display area is simulated in units of a single display, and the layout adjustment between the contents of multiple displays needs to be redesigned. design, iterative design cycles are still long
