CN102855776A - Method for predicating estimated arrival time of flight - Google Patents

Abstract

The invention discloses a method for predicating estimated arrival time of a flight. The method comprises the following steps of obtaining flight time of various flights at each time according to the history flight data of the flights; summarizing the flight time of various flights at each time, calculating an average value, and obtaining a basic reference value of the flight time of the current flight; and calculating to obtain the estimated arrival time of the current flight by combining the actual taking off time of the current flight. The method provided by the invention can be used for effectively and accurately calculating the estimated arrival time of the current flight, thus, the arrangement of an airport pick up plan by pick up staff is greatly facilitated.

Description

Flight estimated time of arrival (ETA) predictor method

Technical field

The present invention relates to the civil aviaton field, be specially a kind of flight estimated time of arrival (ETA) predictor method.

Background technology

At present, generally be provided with at home civil aviaton's data query system in the airport, the information data of each flight is provided to the public by civil aviaton's data query system.Although existing civil aviaton data query system can show flight estimated time of arrival (ETA), in actual conditions, owing to there is the factor such as flight change, causes flight estimated time of arrival (ETA) with actual very large error to be arranged, thereby affect the personnel's that pick the plan of normally picking.

Summary of the invention

The object of the invention provides a kind of flight estimated time of arrival (ETA) predictor method, is applied in civil aviaton's data query system, to solve the larger problem of flight estimated time of arrival (ETA) error in the prior art civil aviaton data query system.

In order to achieve the above object, the technical solution adopted in the present invention is:

Flight estimated time of arrival (ETA) predictor method is integrated in civil aviaton's data query system, it is characterized in that: comprise that historical record screens module, data are estimated module;

Be provided with the historical flying quality of flight in the described historical record screening module, historical record screening module is screened from described historical flying quality, flying quality with each flight of filtering out identical course line, same model, taking off on schedule, and calculate each schedule flight time of each flight, the historical actual time of departure of the historical actual time of arrival-flight of schedule flight time=flight that each flight is each;

Described data are estimated module each schedule flight time of each flight are asked successively summation, average, obtain schedule flight time reference value, data are estimated module and are reached the time according to the expectation that schedule flight time reference value calculates current flight again, current flight the estimated time of arrival (ETA)=current flight the actual time of departure+schedule flight time reference value.

Among the present invention, utilize the historical flying quality of flight, the flying quality of each flight that at first filter out identical course line, same model, on schedule takes off, then try to achieve each schedule flight time of each flight according to the flying quality of each flight in the historical record, then to each schedule flight time of each flight ask summation, averaging obtains current schedule flight time reference value, in conjunction with the actual time of departure of the current flight that obtains from the airport, calculate the estimated time of arrival (ETA) of current flight.

The present invention is in conjunction with the historical flying quality of flight, can effectively and exactly calculate the estimated time of arrival (ETA) of current flight, and the estimated time of arrival (ETA) of the current flight that calculates and actual time of arrival error are less, greatly facilitate the personnel placement that the picks plan of picking.

Embodiment

As shown in Figure 1.Flight estimated time of arrival (ETA) predictor method is integrated in civil aviaton's data query system, comprises that historical record screens module, data are estimated module;

Be provided with the historical flying quality of flight in the historical record screening module, historical record screening module is screened from historical flying quality, flying quality with each flight of filtering out identical course line, same model, taking off on schedule, and calculate each schedule flight time of each flight, the historical actual time of departure of the historical actual time of arrival-flight of schedule flight time=flight that each flight is each;

Data are estimated module each schedule flight time of each flight are asked successively summation, average, obtain schedule flight time reference value, data are estimated module and are reached the time according to the expectation that schedule flight time reference value calculates current flight again, current flight the estimated time of arrival (ETA)=current flight the actual time of departure+schedule flight time reference value.

The implementation example:

Take flight number CA1111 as example:

Obtain flight by Huhehaote of flying to, Beijing from the Flight Information system, the flight actual time of departure is 11:01, and the flight type is 320.Then concentrated by the historical flying quality of flight that to obtain the fly to flight in Huhehaote and type of type Beijing be 320 flight tabulation.Obtain 4 flights, the flight time was respectively 50 minutes, 48 minutes, 46 minutes, 52 minutes.Average, schedule flight time reference value is 49 minutes.According to formula: current flight the estimated time of arrival (ETA)=current flight the actual time of departure+schedule flight time reference value, trying to achieve flight estimated time of arrival (ETA) is 11:50.

Claims (1)

1. flight estimated time of arrival (ETA) predictor method is integrated in civil aviaton's data query system, it is characterized in that: comprise that historical record screens module, data are estimated module;

Be provided with the historical flying quality of flight in the described historical record screening module, historical record screening module is screened from described historical flying quality, flying quality with each flight of filtering out identical course line, same model, taking off on schedule, and calculate each schedule flight time of each flight, the historical actual time of departure of the historical actual time of arrival-flight of schedule flight time=flight that each flight is each;

Described data are estimated module each schedule flight time of each flight are asked successively summation, average, obtain schedule flight time reference value, data are estimated module and are reached the time according to the expectation that schedule flight time reference value calculates current flight again, current flight the estimated time of arrival (ETA)=current flight the actual time of departure+schedule flight time reference value.
