A Novel Fatigue Detection Method of Air Traffic Controller Based on Radiotelephony Communication

Abstract

With the rapid development of the civil aviation industry, the total number of civil aviation transportation flights has continued to increase. The requirements for safe operations and transportation efficiency have become higher. High-intensity work requirements make it easier for air traffic controllers to become fatigued during their stay. Based on the analysis of the current situation of air traffic controllers in civil aviation in China, a fatigue detection algorithm for air traffic controllers based on radiotelephony communication is proposed. In the proposed algorithm, an ATC voice recording is extracted as the parameters including short-term energy, short-term average amplitude, instruction time, short-term average power and short-term average amplitude difference. The extracted parameter are used to form fatigue detection model. Then the mapping relationship between the control voice data and the fatigue state is formed based on the quantified fatigue value of the matched controllers. Finally, based on the training and test data from Air traffic management Bureau at Shandong province, the efficiency of the proposed method is verified.
