Measurement method for workload of air traffic controller

Abstract

The invention provides a measurement method for workload of an air traffic controller. The method comprises the following steps: A, determining a control load measurement index, wherein the control load measurement index comprises an eye movement index and a voice index; B, recording the eye movement index data corresponding to each eye movement index and the voice index data corresponding to each voice index in real time; C, performing factor analysis on the recorded eye movement index data to calculate the eye movement comprehensive factor of the eye movement index data; D, establishing a control load regression model with the eye movement comprehensive factor and the voice index as input factors and the control workload value as an output factor. According to the method, the workload of the controller can be measured in real time without interference, and the practicability is high.

Description

technical field [0001] The invention relates to the field of traffic control in civil aviation, in particular to a method for measuring the workload of air traffic controllers. Background technique [0002] The safety and efficiency of air flight restrict the development of civil aviation, and as the executor of air traffic management, air traffic controllers play a pivotal role in ensuring the safety and efficiency of air flight. It is one of the important factors affecting flight safety and control efficiency. [0003] However, with the increase in the number of aircraft in the sector under its jurisdiction, the air traffic flow continues to increase, and the workload on the controllers has increased significantly. Once the workload value of the controllers reaches a certain threshold, it is very easy to make human errors, which will seriously affect the aviation industry. Security poses a huge security risk. [0004] At present, in the field of controller workload resea...

Problems solved by technology

Among them, the task performance measurement method measures the workload of the operator given by the task by measuring the work performance of the operator to complete the specified task. This method is often not used alone, but is used in combination with other methods to verify the effectiveness of other methods. The subjective measurement method evaluates the workload based on the operator's subjective psychological feeling, and this subjective feeling is easily disturbed by external factors. The same operator performs subjective evaluation on the same task at different times and places, and the results may be inconsistent; secondly, after the work is completed The subjective evaluation cannot be measured in real time, and the subjective evaluation during the work will interfere with the work; the physiological measurement method has high requirements on the conditions of the experimental equipment, and it is necessary to use a special physiological state recording instrument to record changes in physiological indicators. After completion, a large amount of data will be generated, requiring professionals to perform complex data processing; the measurement method based on airspace characteristics defines airspace complexity and establishes a relationship with controller workload, and evaluates controller workload by quantifying airspace characteristics ; This method does not consider the personality characteristics of the controller in the measurement process, and there are certain limitations
