Description

Flight simulator hardware detection system based on WPF

Technical Field

The invention relates to the technical field of flight simulation training, in particular to a WPF-based flight simulator hardware detection system.

Background

The flight simulator is a real-time simulation system which generates corresponding visual pictures, sound special effects and action feedback according to the operation of a pilot. When a pilot operates various devices (a steering column, pedals, an accelerator, buttons and the like) in a simulation cabin or a teacher operates related control keys on a teacher's desk, the operation control devices generate corresponding voltage signals, the voltage signals are converted into digital quantities through an input interface and then are sent to a computer, the computer calculates the received digital quantities through a preset management program and a related mathematical model, then the calculated results are compiled and controlled through an API (application program interface) of flight simulation software, corresponding airplane driving states are driven by related instruments to indicate the corresponding airplane states, related indicator lights on a driving control panel are driven to present the corresponding states, a sound box emits sounds consistent with the operation, and a motion platform is in the corresponding motion states.

The flight simulator is a device for training pilots, and generally comprises a cockpit, interface equipment, various instruments, a vision system and a training computer. The computer is the control center of the flight training simulator. When trainees train, the trainees can perform various operations while sitting in the cockpit: the electric door is opened, the accelerator is pushed and pulled, the flight lever and the rudder are operated, and various data such as flight speed, travel, position, height, wind direction, wind speed and the like can be obtained. The sight system can simulate the scenery where the student is located, the student feels the motions of diving, pitching and circling just like sitting in the airplane during operation, can see various scenery (cloud, fog, river and building) on and off the airplane, and can set various flight environments so as to comprehensively exercise the technology and learn and master various operations with high difficulty and danger. Therefore, as long as the simulation conditions are vivid, the trainees who pass the flight simulation training can immediately drive the airplane to lift off for exercise after the graduation. The prior flight simulator pays attention to the realization of the fidelity and multiple functions of the flight simulator, and is not careless in the aspects of maintenance and repair of the flight simulator, so that the design is attractive, the use is convenient, the function is complete, and the simulator hardware detection system convenient to operate can generate a great pushing effect on the maintenance of the flight simulator.

WPF (Windows Presentation Foundation) is a Microsoft-derived Windows-based user interface Framework that is part of NET Framework 3.0. The method provides a uniform programming model, language and framework, and really does the work of separating interface designers and developers; at the same time, it provides a new multimedia interactive user graphical interface.

The UDP protocol is known as the user datagram protocol, and it is used for processing packets in a network like the TCP protocol, and is a connectionless protocol. In the OSI model, at the fourth layer, the transport layer, is at a layer above the IP protocol.
