Vestibular electrical stimulation space disorientation antagonism device based on near infrared reflectance spectroscopic imaging driving

Abstract

The invention provides a device for monitoring whether a pilot has a flight illusion or not by combining a functional near infrared reflectance spectroscopic imaging device with a gyroscope, judging the type of the flight illusion and enabling a vestibular electrical stimulation device to send a corresponding stimulation sequence to resist the flight illusion in case of a certain flight illusion. The device comprises the functional near infrared reflectance spectroscopic imaging device for acquiring a blood oxygen concentration signal of the cerebral cortex of the pilot in a flying process, identifying the feature of the blood oxygen signal, and judging whether the flight illusion occurs, the gyroscope for detecting the motion condition of the head of the pilot, the vestibular electrical stimulation device for applying vestibular electrical stimulation and changing an input signal of the semicircular canal of the vestibular organ of a human body to resist the flight illusion, and a control computer for controlling a stimulation mode, a stimulation current mode, stimulation current intensity and stimulation time of the vestibular electrical stimulation device, and displaying relevant parameters in real time. The device provided by the invention can monitor the space cognitive state of a person in the flying process, and can apply the vestibular electrical stimulation in time in case of the flight illusion, so as to resist space disorientation.

Description

technical field [0001] The invention relates to the field of aeromedical engineering research, specifically a method of using a functional near-infrared spectral imaging system (fNIRS) combined with a gyroscope to monitor whether a pilot has a flight illusion, determine what kind of flight illusion it is, and trigger when a certain flight illusion occurs. A vestibular electrical stimulator that delivers a sequence of vestibular electrical stimulation to combat the illusion of flight. Background technique [0002] Spatial disorientation, also known as flight illusion, refers to the wrong perception of the aircraft and its own position, attitude, and trajectory during flight. If this kind of erroneous perception is not discovered and dealt with in time, it will easily lead to flight accidents. Current studies believe that the essence of spatial disorientation is that the human body's spatial orientation organs cannot meet the high-speed movement environment in the three-dimen...

Problems solved by technology

Because the pilot cannot realize the occurrence of the flight illusion in time and lacks effective countermeasures, spatial orientation disorder may cause serious flight accidents, resulting in huge economic losses and personal injuries
