Problems solved by technology
In this way, when the flight operation data of each region is aggregated into flight flow sample data, due to the different sources and heterogeneous formats of the flight operation data in each region, the accuracy of the flight flow sample data is greatly affected, and the existing information redundancy The information error caused by the information loss, and the information distortion caused by the loss of information, it is difficult to truly reflect the operation status of air traffic

Embodiment Construction
[0067] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0068] figure 1 It is a flow chart of the method for obtaining flight flow sample data of the present invention, including:
[0069] Step 1, processing the regional flight data of each region into a summary data file;
[0070] Step 2, judging whether there is still flight data in the summary data file, if yes, execute step 3, otherwise execute step 6;
[0071] Step 3, extracting data belonging to the same flight from the summary data file according to the flight identification to form a flight data set;
[0072] Step 4. Perform normalization processing on repeated waypoints in the flight data set according to each waypoint in the flight data set and the time information when the flight passes through each waypoint;
[0073] Step 5. Perform time sorting on the waypoints in the flight data set to obtain a waypoint seq...

The invention relates to a method for acquiring the flight flow sample data. The method comprises the following steps: the data belonging to the same flight is extracted from the summarized data file according to the flight identification, so that a flight data set is formed; the repeated way points in the flight data set are normalized; the time sequencing is performed to the way points in the flight data set to obtain a way point sequence, and the way point sequence is resampled for enhancing the flight path accuracy; and a plurality of way point sequences as the flight flow sample data areoutput. Since the invention performs normalization to the repeated way points, the information error caused by information redundancy of the primary data is effectively eliminated, and since the flight data set is resampled, the information distortion caused by information loss of the primary data is effectively eliminated. Therefore, the accuracy of the obtained flight flow sample data is high, the flight path accuracy is high, and the running conditions of the air traffic can be truly reflected.
Description
technical field [0001] The invention relates to a method for processing flight data, in particular to a method for acquiring flight flow sample data. Background technique [0002] With the rapid development of our country's national economy, the volume of air traffic continues to grow, making it difficult for the existing air traffic management system and technology to meet the needs of development. In order to promote the sustainable development of air traffic, it is urgent to scientifically and carefully analyze the current airspace operation status, identify the bottleneck of air traffic development, improve the existing management system, and introduce new concepts and technologies of air traffic operation. However, the introduction of new concepts and technologies in air traffic operations will inevitably have unpredictable impacts on existing airspace. Whether it is the operation analysis of the existing airspace or the simulation evaluation of the airspace operation ...
