Abstract: A method accurately evaluates a corresponding operation capacity for an operating characteristic of a to-be-evaluated object in a to-be-evaluated time period in combination with already-operated historical data of the to-be-evaluated object, which specifically includes: for a capacity influence factor in an operating process of an airspace unit, constructing a capacity similarity characteristic model to form a capacity similarity characteristic index set; acquiring historical data of an evaluation object, on the basis of the capacity similarity characteristic index set, classifying historical data samples of different time periods by a clustering algorithm, and generating a capacity similarity time period sample set to which an evaluation time period of the current evaluation object belongs; and classifying historical capacity values of the capacity similarity time period sample set by a density clustering algorithm, and calculating a capacity reference value on the basis of a maximum class cluster.

Abstract: A conflict alerting method based on control voice comprises: collecting radio voice messages of a controller and a pilot and converting the radio voice messages into digital signals by an audio card of a control position; converting the digital signals into text messages by a voice recognition function and sending the text messages together to a system server; extracting, by the system server, control commands from the text messages; determining a moving track of an aircraft in a future period of time based on the control commands; identifying a possible dangerous conflict between aircrafts in combination with current location messages, motion parameter messages and future motion tracks of various aircrafts in an air traffic management system, and providing an alert prompt.
