Flight simulation system in Windows operation system environment

Abstract

The invention discloses a flight simulation system in a Windows operation system environment. The flight simulation system comprises a componentized node part, a memory database part and a communication part, wherein the componentized node part is used for providing various node programs in a flight simulator with unified management and registration modes; the memory database part is used for providing data in the componentized node part with a fast indexing and locating mode; the communication part is used for providing the memory database part with unified read-write data interfaces, shielding the complexity of underlying communication detail of the memory database part, providing unified abstraction and improving the flexibility of deployment environment of the flight simulation system. The problems of data management and sharing between simulator nodes are solved, the requirements of the flight simulator in various usage scenarios are met, and the reusability and the portability of codes are achieved.

Description

technical field [0001] The present invention relates to the technical field of flight simulation, more specifically, the present invention relates to a flight simulation system under the Windows operating system. Background technique [0002] With the emergence and development of digital computers, since the 1980s, digital technology has been gradually applied to the development and research of flight simulators. At present, digital flight simulators have become many well-known flight simulator research institutions and manufacturers at home and abroad. main research object. [0003] Foreign companies engaged in the development of flight simulators mainly include CAE and Mechtrontix in Canada, Thales in the UK, Flight Safety and Frasca in the United States, and Thomson in France. Many foreign universities and scientific research institutions have also carried out research work on high-fidelity flight simulators. The famous ones are the Simona Institute of Delft University i...

AI Technical Summary

Problems solved by technology

[0005] Traditional flight simulators rely on a single computer to schedule and calculate the nodes in the simulation system, and it is difficult to greatly improve the performance of a single machine. Therefore, the performance of traditional flight simulation systems based on a single machine is limited by the performance of a single machine

At the same time, a system failure of a single aircraft will cause the entire simulation system to run abnormally, so the flight simulation system based on a single aircraft is less robust

[0006] Existing distributed-based flight simulators usually use the method of segmenting the entire shared memory for inter-node communication. The memory block of each node is mapped to a section of the entire shared memory, and the data is not effectively managed. Difficult indexing and slow search speed

In addition, the existing flight simulator distributed communication mainly relies on GE's VMIC reflective memory card. GE's reflective memory card does not open source code under the Windows operating system, so there are security problems

If you need to build a star network based on the VMIC reflective memory card, you need to use a dedicated switch, and the networking cost is relatively high.

In addition, distributed program development and debugging are more difficult than stand-alone

There is no unified abstract model for each node model of the existing flight simulator, resulting in code redundancy and non-standard problems, which is not conducive to software development and later maintenance
