Abstract
Disclosed are an airport control decision support system and method based on semantic recognition of a controller instruction. The system includes a speech acquisition module, a noise processing module, a speech recognition module, a semantic recognition module, a conflict recognition module, and an alarm display terminal. The system can effectively eliminate accidents and potential accidents thereof caused by human factors in a control process, and can improve safety of aircraft ground operation. Different from ordinary speech recognition and semantic recognition, data annotation of pronunciation and intonation is performed based on special pronunciation of air traffic control, and finally a speech database that conforms to airport control standard phrases is constructed. The airport control decision support system is implemented by installing a speech acquisition device and the alarm display terminal in a control seat, and thus the system is economical and practical.
