Problems solved by technology

This method has a certain corrective and auxiliary effect on the control language, but too much reliance on the theoretical control decision-making method may cause conflicts with the actual situation, and the language that does not match and not output will cause a discontinuous command sequence. can cause problems in

Abstract

The invention discloses a method for recognizing the intention of air traffic control instructions based on regular expressions. The method includes performing standardized extraction of the instruction intention on the input instruction text or instruction text sequence, dividing the text sequence into multiple statement blocks and matching corresponding Label and separate statement blocks; command party and command scene recognition; and integrate output dialogue sequences. The present invention extracts and segments the actual intentions of controller and pilot instruction texts recognized by speech, and adds corresponding scene labels to the instructions, making the instructions clear and clearly indicating the progress of the aircraft in the overall stage of control , improve the command efficiency of controllers, and reduce the probability of control errors.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a regular expression-based air traffic control instruction intention recognition method. Background technique [0002] In large and busy airports, aircrafts take off and land frequently, and the taxiing path on the ground is complex, which is very prone to scene safety accidents. At present, China's air traffic control is still a high-intensity mental work based on the subjective decision-making of the controllers. According to statistics, more than 1 / 3 of the most serious scene safety accidents are caused by the mistakes of the air traffic controllers, mainly concentrated in the controllers. wrong decision. Because high-altitude controllers cannot effectively monitor aircraft, there are many uncertainties, and the substantial increase in traffic has also brought a great load to the controller's work. [0003] At this stage, voice recognition technology has matured, and can r...
