The Design and Implementation of Virtual Aircraft Instruments

Reference to a variety of virtual instruments simulation method, combining the hardware and software resources of the Ground Support Equipment Research Base of CAAC. VAPS (6.3) and Visual C+ + 6.0 are adopted to achieve PC-based design and simulation of virtual aviation instrument in the paper. This paper uses the virtual instrument of atmospheric system as an example to demonstrate the feasibility and reliability of the design philosophy. Simulation modeling is created by different spacing scales instead of array mode in same spacing to modify the parameter to fully accord with requirements by running the simulation program. The calibration line is aliasing rather than being straight on the drawing chart. This paper studies anti-aliasing in software and hardware. It also refers to double buffer technique to finish the aliasing. This can make the continuous of animation effects and eliminate or reduce the aliasing. This paper presents an improved Bresenham line drawing algorithm based on Bresenham line drawing algorithm combing of the symmetry of the virtual instrument to establish a straight line drawing module which is helped to tackle the aliasing through hardware. Finally,the feasibility and reliability of the system are tested and a good display result is got.
