Objective To carry out ergonomic experiments on the mental state of pilots in different aircrafts efficiently in the lab,a mental state evaluation platform based on the general flight simulation system was developed. Methods The platform consisted of the cockpit( including a cockpit bracket,a seat,a joystick and 4 LCD displays),the flight view and cockpit instrumentation system,the flight simulation and control system and the EEG recording system. An EEG experiment system based on the flight tasks was developed and the platform universal design,the real-time design and the data synchronization design were conducted. Results The flight simulation system was established based on the general simulation framework,thus the universality of the platform was ensured and the efficiency of experiments was greatly improved. The designs of the reflective memory network and the capture card ensured the real-time performance of the platform. Conclusion The system could simulate the ground target identification and air target attack tasks. It could be used in pilot mental load assessment,fatigue testing,and ergonomic evaluation of information interface of instrument. The design requirement on the platform was satisfied.
