1) The monitored physiological parameters are: brain electricity, electrocardio, heart rate, respiratory rate, body temperature, blood pressure, blood oxygen saturation (blood oxygen concentration), ear pulse, blink rate, eye level blood pressure and the like. The specific monitoring method and the architecture design thereof are as follows:
a. electroencephalogram: 3 dry-type brain electrodes are arranged on a soft pad at the top part in the helmet and need to be contacted with the skin of the head of a human body when in use. In order to avoid discomfort such as local compression on the head of a human body, a proper concave design is adopted at the part of the hard liner at the top part in the helmet, which corresponds to the brain electrode.

c. Head blood oxygen saturation (blood oxygen concentration): photoelectric blood oxygen sensors on two sides of the nose bridge are adopted and are arranged on a silicon rubber main body at the nose bridge part of the mask. In order to avoid discomfort caused by compression of the nose bridge part when the mask is pressurized, the mask main body and the shell need to be subjected to profiling design. In order to be matched with a special laser fiber sensor, the photoelectric blood oxygen sensor needs to be improved, and the sampling frequency of the photoelectric blood oxygen sensor needs to be increased from the common 50Hz to 200 Hz.
d. Ocular level blood pressure: a special sheet type laser optical fiber sensor is adopted. The laser fiber sensor is arranged between the hard pad and the soft pad at the top part in the helmet and at the position on the left side of the forehead of a human body. In order to avoid discomfort such as local compression on the forehead of a human body, a proper concave design is adopted on the position, corresponding to the laser optical fiber sensor, of the top hard liner in the helmet.
e. Ear pulse: the ear pulse is isolated by a special algorithm using the laser fiber sensor mounted in the helmet.
f. Electrocardio: the five-lead electrocardio-electrode is arranged on a specially-made elastic vest and is required to be contacted with the skin of the upper body of a human body when in use. The heart rate and the respiratory rate can be separated through the electrocardio data.
g. Blood pressure: a special sheet type laser optical fiber sensor is adopted and installed on a special elastic back center, and the back is close to the heart. By adopting a special algorithm, the blood pressure can be measured continuously in real time without sensing, and the heart rate and the respiratory rate can be separated.
h. Finger tip blood oxygen saturation: the finger tip photoelectric blood oxygen sensor and the soft structure are arranged at the index finger tip of the left hand of the protective glove. In order to be matched with a special laser fiber sensor, the photoelectric blood oxygen sensor needs to be improved, and the sampling frequency of the photoelectric blood oxygen sensor needs to be increased from the common 50Hz to 200 Hz.
i. Body temperature: a minitype body temperature sensor is adopted and is arranged on a specially-made elastic dorsal heart and the armpit at the left side.

Monitoring environmental parameters in the aircraft cabin: cabin altitude, cabin internal air pressure, cabin internal oxygen partial pressure, cabin temperature, and the like.
a. The acquisition of the flight environment parameters of the airplane needs to be combined with an airplane system and directly acquired from an airplane flight parameter recording instrument.
b. Acquiring environmental parameters in an airplane cockpit, wherein the environmental parameters need to be combined with an airplane system and directly acquired from an airplane flight parameter recording instrument; or can be combined with an aircraft ejection seat and obtained from an ejection seat program controller. Parameters not related to the ejection seat program controller, such as oxygen partial pressure, temperature in an cabin and the like, need to be added with corresponding sensors to acquire data.
3) Monitoring the flight state parameters of the airplane: overload, speed, dive, pull-up, pitch, roll, fly backwards, etc. The flight state parameters of the plane, such as overload, speed, dive, pull-up, pitching, rolling, reverse flight and the like, can be acquired from a plane flight parameter recording instrument and can also be acquired from an ejection seat program controller.
4) Introducing flight parameters of the airplane: relevant flight parameters, environment parameters (flight altitude, atmospheric pressure, oxygen partial pressure, environment temperature, environment relative humidity and the like) of the airplane flying position, environment parameters (cabin altitude, cabin internal air pressure, cabin internal oxygen partial pressure, cabin temperature and the like) in the airplane cabin, flight state parameters (overload, speed, dive, pull-up, pitch, roll, reverse flight and the like, overload, speed, dive, pull-up, pitch, roll, reverse flight and the like) and the like are directly introduced from an airplane main computer, flight parameters and the like.
(2) The analysis and judgment subsystem has the functions of physiological state representation, physiological parameter calculation, physiological parameter threshold value input and adjustment, physiological parameter and dangerous flight environment correspondence, comparison and judgment and the like. And resolving the monitored physiological parameters into comparable parameters according to a specified mode, comparing the comparable parameters with physiological parameter thresholds, corresponding to dangerous flight environments, analyzing and comparing the parameters related to the comprehensively monitored airplane, and sending a next step execution instruction.
(3) The early warning subsystem has an airplane flight state early warning function and a pilot physiological state early warning function. Through the analysis and judgment of the analysis and judgment subsystem, the early warning is carried out on the condition that the airplane is about to reach a dangerous flight state (exceeding the airplane limit, the dangerous flight state and the like), and the early warning is carried out on the condition that the pilot is about to reach a dangerous physiological state (exceeding the pilot physiological threshold value and possibly influencing the operation of the airplane).
The early warning subsystem early warning is divided into three states, namely a normal state, a dangerous state and an exceeding limit state, and green, yellow and red light and a flat display character are respectively adopted for displaying.
1) And in a normal state, namely the flight state of the airplane and the physiological state of a pilot are normal, the light and the head-up display characters are green and do not flicker, and the buzzer does not sound.
2) The dangerous state comprises an imminent dangerous state or a dangerous state (dangerous flying state and dangerous physiological state), and at the moment, yellow light with slow flicker (such as one flicker in 3-5 seconds), a flat yellow character with slow flicker, and a lighter buzzer for reminding are mainly adopted.
3) The exceeding limit state comprises the exceeding limit state or the exceeding limit state (exceeding the limit of an airplane and exceeding the physiological threshold value of a pilot, namely the physiological limit), and at the moment, the red light which flickers quickly (for example, flickers once in 1-2 seconds), the flat red character which flickers quickly, the buzzer which sounds quickly (for example, once in 1-2 seconds), the human body touch situation perception and other comprehensive ways are mainly adopted for reminding.
(4) The intelligent active protection subsystem has the functions of implementing intelligent protection and active protection.
1) The intelligent protection is corresponding protection performed when the analysis and judgment subsystem analyzes and judges that the flight state will exceed the physiological parameter threshold of the pilot (at the moment, the flight state of the airplane may not be reflected in time). For example, the aircraft flight overload does not exceed the normal tolerance value of the pilot, the anti-overload protection cannot be implemented under normal conditions, but the anti-overload capacity is reduced when the physiological state of the pilot is slightly poor, and the anti-overload protection needs to be implemented on the physiological parameter analysis and judgment result at this time. The aircraft flies at high altitude (such as 12000 m of the actual height of the aircraft), the height in the cockpit does not exceed the specification, and the pressurized oxygen supply is not implemented, but if the pilot wears the mask to be loose, the physiological parameter analysis judges that the pilot is in an anoxic state, and the pressurized oxygen supply protection is needed.
2) The active protection is corresponding protection which is carried out by analyzing and judging the flight state by the analysis and judgment subsystem to cause dangerous flight state (at the moment, physiological parameters may not be reflected in time). For example, the maneuver flight operation action of the aircraft crew may cause a high overload condition through analysis, at this time, because the aircraft does not actually cause the high overload, the physiological parameters of the human body such as ear pulse, eye level blood pressure and the like are not changed temporarily, but the protection system still implements the anti-overload protection in advance.
3) The intelligent active protection is a protection measure taken after the analysis results of the two aspects are integrated.
(5) The awakening subsystem has an awakening function for pilot consciousness loss and an awakening function for pilot dangerous flight state. When the analysis and judgment subsystem analyzes and judges that the pilot is about to be in or is in the consciousness loss state, the awakening device is started to awaken the consciousness of the pilot, and the pilot carries out the next operation. When the analysis and judgment subsystem analyzes and judges that the airplane is about to reach or is in the dangerous flight state at present, the wake-up device is started to wake up the pilot, and the pilot is changed from the dangerous state. The awakening device adopts a rapid sound and strong human body touch perception stimulation mode.
According to the general architecture design, the subsystems and the pilot protection equipment are organically combined and connected in series, and therefore the architecture can be used for building an intelligent pilot protection system quickly and well.
The above is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereby, and therefore, the present invention is not limited by the scope of the claims.
