Abstract

The invention relates to a real-time control device of a flight simulator sound parametric array. A command editing module edits a sound playing control command in advance and stores the same, allowing a sound playing unit to be called at any time; an interface unit receives a control command from a flight simulator and transmits the control command to a sound control unit in a program execution cycle according to a time sequence; the sound control unit determines generation conditions and a change range of a sound signal through systematic need analysis, establishes a mathematical model meeting a real aircraft sound environment and resolves the mathematical model, and transmits resolution results to the sound playing unit; the sound playing unit can select and call a sound source according to the control command, changes the frequency and amplitude of sound, volume and cycle state and constantly keeps the sound to be consistent to the control command of the flight simulator. The real-time control device is simple in structure and convenient to use, allows editing of sound signals, allows multi-path control and output and is highly consistent to the flight simulator sound environment.

Description

[0001] technical field [0002] The invention relates to the technical field of simulation sound control, in particular to a real-time control device for a flight simulator sound parameterized array. Background technique [0003] In a large-scale flight simulator, the realistic sound environment will help the pilot establish a good cockpit environment and help him effectively complete the judgment of the aircraft state. At present, the sound system has become one of the must-have systems for flight simulators. Currently disclosed communication methods are usually purely through hardware to generate sound sources or computer software to generate sound sources. That is, the generation of various noises is realized through circuit design, or the sound signal is generated through the computer, and the playback is completed through program control. The shortcomings of these two methods of sound environment establishment are: the circuit design of the sound source generated by h...
