Study on the development process of apron controller's work fatigue based on heart rate characteristics

Area of Science:

• Aviation Operations
• Human Factors Engineering
• Physiological Monitoring

Background:

• Apron controllers face demanding work environments.
• Understanding controller fatigue is crucial for safety and efficiency.
• Existing methods for fatigue assessment may lack objectivity.

Purpose of the Study:

• To investigate the relationship between physiological data and controller fatigue.
• To establish objective markers for fatigue development in apron controllers.
• To analyze the pattern of heart rate changes during work shifts.

Main Methods:

• Field experiments conducted at Beijing Daxing International Airport.
• Collection of physiological data using smart band sensors.
• Quantitative analysis of duty time, workload, and heart rate characteristics.
• Comparison of heart rate with personnel reaction time.

Main Results:

• Heart rate characteristics correlate significantly (p<0.05) with controller workload and reaction time.
• A jittering decreasing trend in heart rate was observed during a 3-hour work period.
• Relative heart rate decreased from 0.6 to approximately 0.2.
• Statistically estimated confidence intervals for minimal heart rate occurrence and corresponding flight numbers indicate potential fatigue severity.

Conclusions:

• Heart rate serves as an objective indicator of apron controller fatigue.
• The identified patterns of heart rate change can inform fatigue management strategies.
• Findings offer valuable references for optimizing controller shift schedules and monitoring personnel status.
