Pilot mental load measurement system based on flight simulator

Abstract

The invention provides a pilot mental load measurement system based on a flight simulator. The pilot mental load measurement system comprises a flying emergency setting subsystem (1) and a pilot mental load horizontal measurement subsystem (2). The flying emergency setting subsystem (1) is used for setting abnormal information in a cockpit in the flying process; the pilot mental load horizontal measurement subsystem (2) is used for measuring the pilot mental load grade under a flying emergency. The pilot mental load measurement system comprises three modules which are the pilot operation performance index measuring module, the pilot physiological parameter measuring module and the pilot mental load grade judging module. The pilot operation performance index measuring module is used for recording and analyzing the correct operation rate and the reaction time of a pilot to the abnormal information in the flying operation process. The pilot physiological parameter measuring module is used for recording and analyzing change situations of pilot physiological parameters (a heart rate variability index SDNN) in the flying operation process. The pilot mental load grade judging module is used for judging the mental load level of the pilot.

Description

technical field [0001] The invention relates to a measurement system for the pilot's mental load, which can measure the mental load level of the pilot based on the flight simulator to deal with the special situation of the flight, and then measure the rationality of the mental task design of the aircraft cockpit human-computer interaction system. Background technique [0002] With the improvement of flight automation, the main function of the pilot in the human-computer interaction system of the aircraft cockpit has changed from being a manual operator to being a monitor of the aircraft's operating status. The load is greatly increased. Especially when there is a flight situation that needs to be dealt with, the information processing requirements faced by pilots are extremely strict. They often need to process a large amount of flight information in a very short period of time and make quick response decisions, which is prone to high mental load and even overload. This wil...

Problems solved by technology

The subjective evaluation method of the NASA_TLX scale can only be carried out after the flight test, which brings difficulties to the measurement work of the human-computer interaction system design in the early aircraft cockpit. Once a problem is found, the system must be redesigned, and the NASA_TLX scale will be carried out after the test flight again Subjective evaluation, this phenomenon will inevitably cause great waste and consumption of human, financial and material resources

In addition, due to the large inter-individual differences in the subjective evaluation method of the NASA_TLX scale, the evaluation results are easily confused
