The bottom of iron cover 1 cavity is provided with support bar 3, and support bar 3 is provided with the seat 4 that is used to make the pilot take, and seat 4 is provided with vertical strut 5, and vertical strut 5 is fixed with the seat 4 that is used for pilot to take. The position indicator 6 for orientation selection, the inner chamber of the spherical iron cover 1 is ...

Embodiment 2

[0032] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0033] Specifically, the position indicator 6 includes a sphere fixed on the vertical pole 5, and several pressure sensors are arranged on the sphere, and each pressure sensor is evenly distributed on the sphere, and the sphere is provided with A microprocessor, the microprocessor is respectively connected with the central processing unit and each pressure sensor for signals, and the microprocessor and each pressure sensor are respectively electrically connected with the power supply device.

[0034] Since several pressure sensors are arranged on the sphere, and each pressure sensor is evenly distributed on the sphere, like this, each pressure sensor just represents an azimuth, and the central processing unit can know according to the...

Embodiment 3

[0038] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0039] Specifically, the number of the sliding wheels 11 is one and is arranged in the center of the side of the slider 8 facing the inner cavity, and the side of the slider 8 facing the inner cavity is provided with a plurality of evenly distributed and used for auxiliary sliding wheels 11 Training wheels 9 for stable operation.

[0040] In this embodiment, the auxiliary wheel 9 makes the slider 8 run more stably. Meanwhile, the material of the auxiliary wheel 9 is consistent with that of the sliding wheel 11 , which is also the material of the magnet.

[0041] In this embodiment, the auxiliary wheel 9 includes a connecting rod 9-1 fixed on the slider 8, the free end of the connecting rod 9-1 is provided with a universal wheel 9-2, an...

Abstract

The invention discloses a pilot space auditory ability training system, which comprises a spherical iron cover, a door is opened on the spherical iron cover, a support column for supporting the spherical iron cover is arranged under the spherical iron cover, and the inner cavity of the spherical iron cover is The bottom of the seat is provided with a support bar, the support bar is provided with a seat, and the seat is provided with a vertical pole. A position indicator for pilots to select azimuth is fixed on the vertical strut. The inner cavity of the spherical iron cover is provided with a slider, and the side of the slider facing the inner cavity is provided with a sliding wheel, and the sliding wheel is controlled by a universal drive. drive, the material of the sliding wheel is a magnet, the side of the slide block facing the seat is provided with a sound source for playing sound, and the slide block is also provided with a gyroscope. The invention randomly simulates the sound signal within 360 degrees, and allows the pilot to judge the aircraft and point out the position of the sound, and compares the position of the sound pointed out by the pilot with the actual sound position, so as to train the pilot's ability to perceive space hearing .

Description

technical field [0001] The invention relates to the technical field of flight training, in particular to a pilot spatial hearing ability training system. Background technique [0002] Flight personnel often face complex air situations, and maintaining good spatial orientation perception is very important to prevent human errors. Because the human spatial orientation system itself can cause ambiguity, such as the inability of otolithic organs to distinguish gravity and inertial forces, it leads to the illusion of body gravity. Therefore, it is meaningful to look for a cue to improve spatial perception outside the orientation perception system. [0003] Sound localization refers to judging the position of a sound source in three-dimensional space based on sound clues, including the interaural time difference and sound level difference, and the monaural spectrum information formed by the head-related transfer function. However, changes in the anatomical structure of the ear, ...
