6 results about "Air traffic control" patented technology

A method and system are described for enhancing ground situational awareness to an aircrew via an alphanumeric display of an air traffic control ground clearance, including displaying a symbol for each stage of the clearance. A crewmember may accept or change each stage via a graphical user interface within the alphanumeric display.

The invention relates to a flight operation data fusion method and device, and belongs to the technical field of data fusion, the method can accurately fuse various flight operation data belonging tothe same flight plan, and a designed association primary key and the fusion method can well process data splitting easily caused by flight delays and other abnormal conditions; various flight operation data of an air traffic control production system can be received and processed in real time, a latest data fusion result is generated immediately after the production system sends out the data, andcentralized processing does not need to be carried out in the future; according to the invention, various flight operation data generated by a plurality of air traffic control production systems can be fused, the processed data is more comprehensive, and the application range of a fusion result is wider.

The invention discloses an air traffic control monitoring response signal feature extraction method and device, equipment and a storage medium, and the method comprises the steps: obtaining an A/C mode response signal and an S mode response signal, and carrying out the signal preprocessing of the A/C mode response signal and the S mode response signal; obtaining a response signal set with an A-mode code label and a response signal set with an S-mode code label; performing self-Wigner distribution on all signals in the response signal set with the A-mode code label and the response signal set with the S-mode code label, and taking absolute values to obtain a matrix serving as feature extraction input; and calculating a Fisher discriminant ratio of the matrix as feature extraction input, and selecting a point with the maximum Fisher discriminant ratio as a signal feature according to a preset number of to-be-extracted features. According to the invention, preprocessing and time-frequency conversion are carried out on the collected response signals, and then feature extraction is carried out, so that each airborne response device forms a signal-level feature of the airborne response device, and a signal-level feature library of the airborne response devices is formed.

An air traffic control system includes one or more servers each including a network interface, a processor, and memory; and a database communicatively coupled to the one or more servers, wherein the network interface in each of the one or more servers is communicatively coupled to one or more passenger drones via a plurality of wireless networks at least one of which comprises a cellular network; wherein the one or more servers are configured to obtain operational data from a passenger drone, obtain conditions from one or more of the operational data and the database, determine a future flight plan based on the operational data and a flying lane assignment for the passenger drone, determine potential collisions in the future flight plan based on static obstructions and dynamic obstructions, obtained from the database based on the future flight plan, and provide evasive maneuver instructions to the passenger drone.
