Embodiment 1

[0060] like figure 1 , figure 2 As shown, the controller's work fatigue monitoring system provided by the embodiment of the present invention includes a conventional work call function, and a blood volume and pulse sensor 2 (PPG) is added on the side of the receiver 1. When working, the blood volume and pulse sensor 2 is sandwiched between the On the earlobe of the aircraft, the collected pulse wave signal can be transmitted to the data analysis platform 6 through the controller's work fatigue monitoring system cable, the hand-held call switch 3, the audio interface 4 and the USB interface 5. The controller is observing the aircraft running status display During the working process of module 6-1, the controller's normal state, mild fatigue state and severe fatigue state calculated by the data analysis platform; The controller's working status is displayed in the form of green light, yellow light and red light.

[0061] The audio interface 4 is plugged into the audio socket ...

Embodiment 2

[0076] like Figure 4 As shown, the controller work fatigue monitoring method provided by the embodiment of the present invention includes:

[0077] After the start, the system first determines whether the controller's work fatigue monitoring system plug is inserted into the data analysis platform 6, and after insertion, completes the power-on, turns on the hand-held communication switch 3 and starts to work. If there is no insertion, no work is performed.

[0078] After starting to work, the blood volume pulse sensor 2 starts to collect the volume pulse blood flow signal. The collected signal is a current signal. The signal cannot be used directly after being filtered and amplified. Therefore, the signal first passes through the current / voltage conversion circuit to realize the current signal direction. Voltage signal conversion, because the signal contains a lot of noise interference, power frequency interference, etc., so the signal needs to be filtered, so the converted p...

Embodiment 3

[0094] In the controller work fatigue monitoring provided by the embodiment of the present invention, the data calculation process includes:

[0095] The data takes 10 seconds as a time segment. After each time segment is collected, the system automatically calculates the data, obtains the corresponding SDNN value and LF / HF value, and compares the value with the threshold value.

[0096] The calculation formula of each time segment data is:

[0097]

[0098]

[0099] N represents the total number of main wave peaks in the pulse wave cycle collected by each data segment.

[0100] like Figure 5 As shown, the determination of the reference value includes:

[0101] Because the controller is in the best state of mind at the beginning of work, in order to improve the accuracy of the data, the data obtained 10 minutes before the start of work is used as the benchmark data, and there are 60 data fragments in 10 minutes.

[0102]

[0103] After 10 minutes, the monitoring and...

Abstract

The invention belongs to the technical field of data information processing, and discloses a controller work fatigue monitoring method and system, computer equipment and a medium. The controller work fatigue monitoring method comprises the steps that a blood volume pulse sensor transmits collected and processed heart rate variability signals to a data analysis platform, and the data analysis platform compares and analyzes the collected and processed heart rate variability signals with a set threshold value; and displaying the lamps with different colors based on the comparative analysis result. According to the invention, on one hand, the blood volume pulse sensor (PPG) is clamped on the earlobe of the controller, so that the data can be accurately acquired, and the normal work of the blood volume pulse sensor is not influenced; on the other hand, whether the airplane is fatigue or not and the fatigue level are prompted through red light, yellow light and green light, and the fatigue state can be prompted while a controller is not affected to command the airplane to operate in a voice communication mode. In conclusion, the application prospect is very wide.

Description

technical field [0001] The invention belongs to the technical field of data information processing, and in particular relates to a controller work fatigue monitoring method, a controller work fatigue monitoring system, computer equipment and a computer-readable storage medium. Background technique [0002] Civil aviation air traffic controllers are tasked with preventing aircraft collisions and ensuring smooth air traffic. They need to focus on processing visual and auditory information. When the controller is physically ill, has less sleep time, and works too long, it is easy to cause the controller to be physically and mentally fatigued, which makes it difficult to concentrate, and the ability to reflect and make decisions declines, resulting in the emergence of air traffic control work. errors, posing a serious threat to aviation safety. [0003] PPG (Photo Plethysmo Graphy, photoplethysmography) is a non-invasive detection method developed based on Lamber-Beer law and l...
