Abstract

The invention discloses an airport control decision support system and method based on controller instruction semantic recognition. The system comprises a voice acquisition module, a noise processingmodule, a voice recognition module, a semantic recognition module, a conflict recognition module and a display alarm terminal. The method has the advantages that accidents and accident signs caused byhuman factors in the control process can be effectively eradicated, so that the ground operation safety of the airplane can be greatly improved. Different from common speech recognition and semanticrecognition, data annotation of speech intonation is carried out for specific speech pronunciation of air traffic control, and finally a speech library conforming to airport control standard terms isconstructed. The airport control decision support system does not need to be assisted by a field monitoring radar, does not depend on an advanced scene activity guide control system, does not need toinstall or reform any equipment outside a control seat, only needs to install a voice acquisition device and a display alarm terminal on the control seat, and is extremely economical and practical.

Description

technical field

[0001] The invention belongs to the technical field of airport flight area operation management, and in particular relates to an airport control decision support system and method based on controller instruction semantic recognition. Background technique

[0002] The current semantic recognition system is not aimed at airport operations, especially the control instructions for aircraft ground taxi guidance, because the recognition rate of speech recognition technology cannot meet the safety requirements of airport air traffic control for the time being, and the Due to the limitations brought about, the semantic recognition of control instructions has not been taken seriously; on the other hand, due to the unique voice pronunciation of air traffic control, it is necessary to build a special voice database. The existing airport control decision-making support system needs equipment assistance such as field surveillance radar, or relies on advanced surface movem...

Examples

Embodiment Construction

[0033] Below is that the present invention is described in further detail:

[0034] The airport control decision support system based on controller command semantic recognition provided by the present invention includes a voice collection module, a noise processing module, a voice recognition module, a semantic recognition module, a conflict recognition module and a display alarm terminal; wherein the voice collection module is used to collect airport control The voice conversation between the controller and the pilot on the seat; the noise processing module is used to filter the VHF communication noise and the high background noise of the airport in the voice conversation collected above to reduce noise interference, and add an amplifier to improve the signal-to-noise ratio ;The speech recognition module is based on the controller's special voice library, and according to the voice characteristics of the controller and the pilot, it performs speech recognition on the speech di...
