Shulou(Shulou.com)06/03 Report--

The development of avionics equipment, especially avionics display system, puts forward higher and higher requirements for safety and development efficiency. VAPS XT is Presagis 'next-generation dynamic, interactive, real-time and graphical human-computer interface development tool. It is the ideal human interface development tool for advanced cockpit instrument design and applications, with a new user-extensible core architecture and integrated logic design capabilities. VAPS XT has all the necessary features for the entire graphics development workflow: from preliminary design through prototyping and simulation, development, testing, documentation and final certification. VAPS XT adopts object-oriented C++ development technology and conforms to aviation DO-178B/C standard. At present, it has been widely used in the development of man-machine interface of Airbus, Boeing, Loma and other aircraft.

Applications & Cases

● Application of VAPS XT in UAV intelligent algorithm verification

UAV is characterized by a certain degree of intelligence, and these intelligences are realized by its intelligent decision-making algorithms. This puts new demands on unmanned platform testing. The human-computer interaction terminal made by VAPS XT can display various flight parameters, flight routes, and three-dimensional visualization information of UAV sensors. The application of VAPS XT realizes dynamic intervention in the process of algorithm function test and real-time and visual output of simulation results. The following figure shows the effect diagram of UAV intelligent algorithm verification platform combined with STAGE and VAPS XT in an institute of AVIC:
