Description
Technical Field
The invention relates to the field of civil aviation security scheduling supervision, in particular to a flight fatigue value calculation method, a device, electronic equipment and a storage medium.
Background
A plurality of airlines in China currently run qualification approval rules of public aviation transportation carriers of large-scale airplanes of CCAR-121-R7 and AC-121-FS-014CCThe fatigue management requirement of the AR121 part qualification holder establishes the fatigue risk management requirement, at present, a scientific analysis method which is internationally accepted for fatigue risk management is a biological mathematical model, and the fatigue, namely the change trend of alertness, of a human body is predicted based on different fatigue theoretical models, so that the potential fatigue risk of a pilot in operation is predicted. The biological mathematical models widely used at present are: fatigue assessment tools (FAID), boeing Alertness Models (BAM), crew fatigue assessment Systems (SAFE), and the like; wherein the first two models are implemented based on a three-process model, known for fatigue prediction, are disclosed in, for example, the following documents: michael Ingre, wessel Van Leeuwen, tomas Klemets, christer U1lvetter, stephen Hough,Kecklund，David Karlss，/>"Validating and Extending the Three Process Model of Alertness in Airline Operations" (PLoS One, volume 9, phase 10, 2014). The model considers three main components, the first component being the circadian process, describing the circadian variation (C) of alertness; the second component is a steady state process describing a decrease in alertness with awake time and a recovery with sleep time (S); the third component is the sleep inertia process, which describes the delay (W) after waking up before alertness resumes. Since the sleep inertia process has little effect after half an hour after waking and the pilot does not work immediately after waking, it is generally not considered in the biological mathematical model of the pilot. One problem with this approach is that it assumes a regular sleep schedule, e.g., work on the nine-night five-week side, while pilot work is possible during any period of 24 hours of the full day that meets regulatory requirements, the pilots have individual differences between them due to differences in sleep habits that are inherited and developed by the acquired lifestyle that determine the peak circadian rhythms, and that need to be considered in the model, pilots of domestic airlines are typically on the fly of the fly on the fly of the nine-night five-week sideThe full physiological and psychological recovery is obtained on the rest days of the two days, the phase peak value can be obtained by utilizing the sleeping condition of the rest period, in addition, the sleeping time required values under different conditions of the working days and the rest days are considered when a model is designed, and the relationship between the fatigue rate and the sleeping time of different pilots when the pilots are awake is also considered, so that a biological mathematical model suitable for the pilots is formed.
On the basis of obtaining the pilot individual fatigue prediction value through a biological mathematical model, the operation control department of the airline company and the unit scheduling department need to further master the fatigue condition of the flight to be performed in operation management, and how to scientifically evaluate the fatigue values of different crew members for scheduling flights is achieved, so that the operation safety level of the airline company is improved (if the fatigue value of the flight to be performed is higher, the airline company needs to be alert and reasonably schedule in time), the technical problem to be solved is solved urgently at present, and no calculation method and system for the flight fatigue value exist in the prior art.

As shown in fig. 1 to 3, a flight fatigue value calculating method includes:
s1, acquiring scheduling information of a flight crew to be flown, wherein the scheduling information comprises pilot work numbers, pilots, pilot work starting time and flight numbers, flight work ending time and flight numbers, and pilots comprise a captain and a copilot; the method comprises the steps of obtaining sleep logs of at least two complete natural days of a pilot of a flight crew to be flown before a pilot work starting time (in order to better adapt to a biological mathematical model, the two complete natural days are natural days of the pilot of the flight crew to be flown at least including a night sleep interval opportunity before the pilot work starting time, the night sleep interval is a time interval from 0 late to 6 early, namely a time interval from 0 early to 6 early), and the sleep logs comprise a sleep-in time, a sleep-out time and sleep efficiency (the value of the sleep efficiency is 0 to 100 percent). This example illustrates the following table:

The best or ideal application of the invention is to arrange the pilots to form the flight crew of the flight to be flown under the condition that the fatigue value of the pilots is relatively lowest, and of course, the domestic and international flights are relatively busy, the pilots of the flight crew comprise the captain and the copilot, and the airlines are more hopeful to pay attention to the fatigue value F of the flights of the flight crew from the practical application of civil aviation operation economy decision Flight (1 … n) The invention can scientifically quantify the flight fatigue value sequence, and is convenient for aviation publicityAnd the department of control and unit scheduling carries out decision consideration. Of course, the invention can also draw the flight fatigue value curve according to the flight fatigue value sequence in the mode of figure 2, which is convenient for visual inspection.
In some embodiments, the fatigue value sequence calculation method in the biological mathematical model is as follows:
s11, acquiring the sleeping time t1 of the first day of two complete natural days before the working start time of the pilot in the sleeping log To fall asleep Time t1 of falling asleep Go out to sleep Sleep efficiency sq1, sleep time t2 of the second of two complete natural days before pilot work start time To fall asleep Time t2 of falling asleep Go out to sleep Sleep efficiency sq2; the circadian rhythm calculation method is as follows:
sleep duration b=0.5 (t 1 Go out to sleep -t1 To fall asleep )*sq1+0.5*(t2 Go out to sleep -t2 To fall asleep )*sq2；
Peak time t of circadian rhythm of pilot Peak value ＝t2 Go out to sleep +12-0.5*B；
Circadian rhythm c=2.5 x cos ((pi/12) (t-t) Peak value ) Where t is the time at which the fatigue value is to be calculated, t is not earlier than the pilot's start of operation, and t generally selects a time period during the flight to effect calculation of the entire flight period. The time involved in the present invention (including t1 Go out to sleep 、t1 To fall asleep T2 out, t2 To fall asleep Time of participation in mathematical operations, t, etc.) are digitally converted according to a 24-hour system, for example: a1 hours A2 minutes (A1: A2), the digitization is converted intoExamples are as follows: 6:30 (digital conversion: 6.5), 20:15 (digital conversion: 20.25).
For example: based on the sleep log example, the sleep duration b=7.97 hours, the circadian peak time t Peak value ＝15.02。
Steady state s=s2=2.4+ (sw-2.4) ×exp (-0.0353×taw×pw) in awake state, where sw is steady state value at the beginning of wakefulness, taw is timing value of the awake state from the beginning of wakefulness, fatigue adjustment factor pw= (24-B)/16 (e.g., pw=16.03/16 based on sleep log example).
In some embodiments, a steady-state training model is built in the biological mathematical model and trained, the steady state in step S11 is composed of a sleep steady state and an awake steady state cyclic connection, and the sleep steady state S1 is divided into two stages, and the calculation formula includes:
when s1 is less than or equal to 12.2, s1=ss+ 0.80073 xtas, (1)
When S1 is more than 12.2, calculating an intermediate variable bt= (12.2-ss)/0.80073; calculating s1=14.3-2.1 x exp (-0.3813 (tas-bt)); (2)
Wherein SS is a steady state value at the beginning of sleep, tas is a timer value from the beginning of sleep in sleep state, and the maximum value of tas prediction is Max ((t 1) on the pilot's rest day (pilot is typically the second of the fly and rest day is the date in second of the rest day) Go out to sleep -t1 To fall asleep )x sq1，(t1 Go out to sleep -t1 To fall asleep ) Sq 2), on the pilot's working day (pilot is typically the second to first day in "second to fourth") the maximum value of tas prediction is the sleep duration B physiologically needed by pilot.
The sleep steady state S1 is calculated by selecting an adaptive formula (1) and an adaptive formula (2) by taking a steady state value ss at the beginning of sleep as an initial value, and then the sleep steady state S1 is calculated by selecting the adaptive formula (1) and the adaptive formula (2).
For example, based on the sleep log example, on the weekdays, the maximum value of tas is 8.33 hours, and on the weekdays the maximum value of tas is 7.96 hours.
Steady state s=s2=2.4+ (sw-2.4) ×exp (-0.0353×taw×pw) in awake state, where sw is steady state value at the start of wakefulness, taw is timing value from the start of wakefulness in awake state, and fatigue adjustment factor pw= (24-B)/16. Steady state s=s1 during sleep state, steady state s=s2 during awake state; since pilot operation is in the awake state, the present invention adopts steady state S2 in the awake state.
S12, calculating an original fatigue value D according to the following formula:
d=s+c; when D is more than 11.7, the sleep state is realized, and when D is less than or equal to 7.5.
Calculating a fatigue value F of the pilot according to the original fatigue value D, wherein F=k represents D+b, k represents a coefficient, and b represents a constant; based on scientific research, k= -0.6, b=10.2 was taken.
And sequentially calculating a fatigue value sequence of the pilot in the flight period according to the steps S11 and S12, wherein the fatigue value sequence is arranged in time sequence.
S2, acquiring flight time accumulated by a length and a copilot of a flight unit to be flown to obtain the length flight time T of the flight to be flown Machine length Flight time T of co-pilot to be flown Co-driving An initial fatigue weighting coefficient database is constructed and set, wherein the initial fatigue weighting coefficient database comprises the corresponding relation between the flight time of the aircraft length and the initial fatigue weighting coefficient and the corresponding relation between the flight time of the co-pilot and the initial fatigue weighting coefficient.
In some embodiments, the length of flight in the initial fatigue weight coefficient database corresponds to the initial fatigue weight coefficient as follows:
long flight time T Machine length Less than or equal to 500, P Machine length ＝0.2；
Long flight time T Machine length E (500, 2000), then P Machine length ＝0.3；
Long flight time T Machine length More than or equal to 2000, P Machine length ＝0.6。
In some embodiments, the co-pilot flight time-of-day versus initial fatigue weight coefficients in the initial fatigue weight coefficient database is as follows:
co-pilot flight time T Co-driving Less than or equal to 1000, P Co-driving ＝0.1；
