CN102880791A - Method for estimating airport arrival/departure speed - Google Patents

Abstract

The invention discloses a method for estimating airport arrival/departure speed, which includes the following steps: obtaining the current taking off and landing data of flights at an airport as per a civil aviation data query system; then obtaining the current total airport arrival/departure flights through the taking off and landing data of flights; and finally, obtaining the flight arrival/departure speed through the formula. Through the adoption of the method, the civil aviation data query system can be used for providing the flight arrival/departure data of the airport based on the fact that the flight basic data is provided by the system, thereby bringing convenience for civil aviation working personnel and users concerned about the flights in estimating the arrival/departure time of the flights.

Description

The speed predictor method is advanced/leaves the port on the airport

Technical field

The present invention relates to civil aviaton data algorithm field, be specially a kind of airport and advance/leave the port the speed predictor method.

Background technology

At present, airport, airline generally are provided with civil aviaton's data query system at home, and to the interior employee, and the public provides the information data of each flight by civil aviaton's data query system.Existing civil aviaton data query system lacks the key factor that current air station flight advances/leave the port speed owing to the algorithm reason, therefore can't to seize the opportunity the people, send the machine people, pick people and other user in predicting flights of being concerned about flights advance/go out ETA estimated time of arrival.

Summary of the invention

The object of the invention provides a kind of airport and advances/leave the port the speed predictor method, can't provide the airport to advance/leave the port the problem of speed to solve existing civil aviaton data query system.

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

The speed predictor method is advanced/leaves the port on the airport, is integrated in civil aviaton's data query system, it is characterized in that: comprise enquiry module, screening module, computing module; Described enquiry module utilized the selected airport A of the Scheduled Flight data query in civil aviaton's data query system to advance/leave the port flight sum F in T hour, described screening module was advanced in T hour/is left the port among the flight sum F, filter out the flight sum I that current time airport A is actual to be advanced/leave the port, by formula V=T/I the computing of described computing module obtains that airport A flight advances/leave the port speed V in current T hour, and computing module obtains according to formula M=I/F computing also that airport A flight advances/leave the port load M in current T hour.

The present invention at first determines that by flight dynamic data in civil aviaton's data query system the flight sum is advanced/leaves the port on a certain airport in a certain period, obtains by formula V=T/I then that flight advances/leave the port speed V in a certain period.

The present invention additionally provides relevant air station flight to advance/leave the port the information of speed on the original Scheduled Flight data of civil aviaton's data query system basis, the user is being understood outside the flight dependency basis notebook data demand, knowing simultaneously air station flight advances. and the speed of leaving the port makes things convenient for the user to judge that current own flight predicts ETA estimated time of arrival.

Embodiment

As shown in Figure 1.The speed predictor method is advanced/leaves the port on the airport, is integrated in civil aviaton's data query system, it is characterized in that: comprise enquiry module, screening module, computing module; Described enquiry module utilized the selected airport A of the Scheduled Flight data query in civil aviaton's data query system to advance/leave the port flight sum F in T hour, described screening module was advanced in T hour/is left the port among the flight sum F, filter out the flight sum I that current time airport A is actual to be advanced/leave the port, by formula V=T/I the computing of described computing module obtains that airport A flight advances/leave the port speed V in current T hour, and computing module obtains according to formula M=I/F computing also that airport A flight advances/leave the port load M in current T hour.

Take Beijing Airport as example:

(1) in civil aviaton's data query system, inputs Beijing Airport.

(2) inquiry obtains leave the port 80 of flight sums of Beijing Airport plan in last hour.

(3) screening Beijing Airport actual 50 of flight sums of leaving the port in last hour.

(4) calculate according to formula V=T/I that flight entering and leaving port speed is 1.2 minutes/frame in the nearest T of Beijing Airport hour; Try to achieve according to formula M=I/F that to advance (going out) port load number percent in the nearest time T hour be 62.5%.

Claims (1)

1. the speed predictor method is advanced/leaves the port on the airport, is integrated in civil aviaton's data query system, it is characterized in that: comprise enquiry module, screening module, computing module; Described enquiry module utilized the selected airport A of the Scheduled Flight data query in civil aviaton's data query system to advance/leave the port flight sum F in T hour, described screening module was advanced in T hour/is left the port among the flight sum F, filter out the flight sum I that current time airport A is actual to be advanced/leave the port, by formula V=T/I the computing of described computing module obtains that airport A flight advances/leave the port speed V in current T hour, and computing module obtains according to formula M=I/F computing also that airport A flight advances/leave the port load M in current T hour.
