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.

Abstract

The invention discloses a pilot space hearing ability training system. The pilot space hearing ability training system includes a spherical iron cover; the spherical iron cover is provided with a door; support posts for supporting the spherical iron cover are arranged under the spherical iron cover; a support rod is arranged at the bottom of the inner cavity of the spherical iron cover; a seat isarranged on the support rod; and a vertical support rod is arranged on the seat. A position indicator for the pilot to perform azimuth selection is fixed on the vertical support rod; a sliding block is arranged in the inner cavity of the spherical iron cover; a sliding wheel is arranged on the side of the sliding block facing the inner cavity; the sliding wheel is driven by a universal driver; thematerial of the sliding wheel is a magnet; a sound playing source for playing a sound is arranged on a side of the sliding block facing the seat; and a gyroscope is also arranged on the sliding block. According to the invention, sound signals are randomly simulated within 360 degrees, the pilot judges and points out the position of the sound by using the aircraft, and the position of the sound pointed by the pilot is compared with the actual position of the sound, so that the hearing sensing ability to the space of the pilot is trained.

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, ...
