Pilot fatigue pre-warning seat

Abstract

The invention discloses a pilot fatigue pre-warning seat. The pilot fatigue pre-warning seat comprises a cushion. The cushion is connected with a backrest, a sliding groove is formed in the backrest,the sliding groove is slidably connected with a connecting rod, the connecting rod is connected with a helmet, and the helmet is internally provided with a heart rate sensor; an anti-g waist belt andan anti-g leg belt are arranged on the two sides of the backrest correspondingly, and the cushion is provided with an air pump and a sucking pump which is used for inflating and pumping the anti-g waist belt and the anti-g let belt; the backrest is provided with an acoustic and a stimulation device; the cushion is provided with a fatigue monitoring device, a processor and a power supply device. According to the pilot fatigue pre-warning seat, whether the pilot is fatigue or not is judged through detection of the change of pressure valves of different parts of a haunch in the flying process ofa pilot and the change of myoelectricity signals, if the pilot is fatigue, then the pilot raises the vigilance through physical stimulation, if the pilot is fatigue for multiple times, the co-pilot isadvised to pay attention to operation, and thus the safety of aircraft operation is ensured.

Description

technical field [0001] The invention relates to the field of flight equipment, in particular to a pilot fatigue warning seat. Background technique [0002] With the in-depth advancement of national defense and military reforms, the Air Force is also transforming towards the strategic goal of "air-space integration, both offensive and defensive", and the intensity of actual combat training for military pilots is bound to further increase. On the one hand, military flight activities are air missions with high risk and complex human-computer interaction, which require pilots to devote a lot of mental and physical resources to maintain good flight capabilities. On the other hand, with the rapid replacement of new-generation fighter jets, pilots have increasingly become a relatively weak link in the "man-machine-environment-mission system". When unable to bear the huge mental load, the pilot will have a decline in physiological and psychological functions, which will cause a red...

Problems solved by technology

Although the reliability and validity of subjective measurement methods to assess the subjective degree of workers are good, they cannot truly reflect the degree of physical and mental function decline of fatigued personnel

In addition, objective detection methods of physiological function changes, such as the activation state of brain regions, heart rate variability (HRV), eye behavior indicators, blood pressure pulse changes, neuroendocrine changes, etc. are considered indispensable for fatigue assessment methods, but some methods still do not meet the conditions for large-scale popularization and application among pilot groups due to complex theory and difficult operation
