Embodiment
For further illustrating each embodiment, the invention provides drawings attached.These accompanying drawings are a part for disclosure of the present invention, and it is mainly in order to illustrate embodiment, and the associated description of instructions can be coordinated to explain the operation principles of embodiment.Coordinate with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present invention.Assembly in figure not drawn on scale, and similar element numbers is commonly used to assembly like representation class.
Now the present invention is further described with embodiment by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 3, the dynamic constant value method of the preferred embodiment ATFM practical operation standard of the present invention.It comprises the following steps,
S1, sets up aerial traffic flow data storehouse, stores the historical data of the magnitude of traffic flow;
From air traffic control system (ATCS) (comprising Air Traffic Flow Management System, air traffic control service system etc.), derive sail plan, air traffic in real time dynamically and the data such as navigational intelligence, set up air traffic database.The historical data of air traffic is stored in traffic flow data storehouse.
S2, obtains the parameter of statistical nature as dynamic value model of historical traffic flows value;
The statistical nature of traffic flow value is according to the historical data in traffic flow data storehouse, regulatory area, calculates under particular sample condition, and under the particular sample cycle, the history maximal value of traffic flow value, history minimum value are or/and history average.The statistical nature of historical traffic flows value is as the parameter of dynamic value model, and dynamic value model designs with reference to statistical nature.
Consult shown in Fig. 2, according to the history value of flow value in traffic flow data storehouse, drawing out the change curve of the history maximal value of once transport air flow value in each relevant space-time, history minimum value and history average, providing scientific basis for setting up rational ATFM practical operation standard.From the historic dynamic data of air traffic that certain air traffic control service unit experiences safely, the air traffic history maximal value corresponding with its air traffic control service virtual rating and history average can be excavated, wherein, that line uppermost is the history maximal value curve of the magnitude of traffic flow, and that line bottom is the history average line of circulation flow.T1, T2, T3 ... for the statistical characteristics of period per hour, flight flow is added up by the hour, therefore with T1, T2, T3 of surely occurring in the same day ... period.
S3, according to the performance management target of ATFM, designs dynamic value model;
According to the performance management target of ATFM, design dynamic value model, form the magnitude of traffic flow and be worth the rule of excavating.By dynamic value model, excavate the practical operation standard dynamic value that ATFM is worth, control air traffic dynamically.By the practical application of user to air traffic practical operation standard dynamic value data, according to ATFM performance objective, continue to optimize dynamic value model and data value excacation.
To the ATFM target that the setting of this air traffic control unit " is born not higher than history maximal value and is not less than history average ", then can set practical operation standard dynamic value is median between history maximal value and history average or mean value.With under guarantee air traffic safety prerequisite, give full play to air traffic control service ability, obtain better ATFM effect.
It should be noted that, according to different ATFM targets, different true-time operation standards can be set.The dynamic value that practical operation standard is chosen, as long as meet ATFM target, any value all can, but for definitely to control traffic safety, and for obtaining best ATFM effect, practical operation standard dynamic value is generally less than history maximal value.
For particular air traffic control unit, in the historic dynamic data continuous print of traffic aloft situation (mass data as long term accumulation), obtain T1, T2, T3 continuously ... Deng the ATFM practical operation standard of sampling instant, and formative dynamics value, routinely instruct air traffic control service work.
When the parameter adopting different statistical characteristics as dynamic value model, by the different air-traffic safety of embodiment and air traffic control ability orientation degree.Therefore, also the different statistical nature of design and dynamic value model can be passed through, effectively to match with air traffic safety management expectancy and air traffic control service ability, and to obtaining best ATFM usefulness.
S4, exports the practical operation standard dynamic value of the magnitude of traffic flow.
Practical operation standard dynamic value is not fixing single numerical value, but is made up of the traffic flow value of each particular point in time, and each feature time point adopts different communication flow values.
Consulting shown in Fig. 3, is air traffic practical operation standard dynamic constant value result of the present invention.Transverse axis is time shaft (being set as 24 hours), the longitudinal axis is the dynamic value of air traffic practical operation standard, the solid line that figure intermediate cam form point is formed is history peak value (peak value and maximal value), the dotted line that square points is formed is history average, the dynamic value of practical operation standard is the dotted line that round dot is formed, and the horizontal thick straight line of black is traditional volumetric standards.
As can be seen from the figure, when flight amount is lower than traditional volumetric standards, with traditional volumetric standards for practical operation standard implementation ATFM; When flight amount is higher than traditional volumetric standards, according to dynamic constant value standard implementation ATFM.At peak hours/period (as the 10:00-21:00 of this control unit area this day of regulatory service; The 10:00-21:00 of this day is served with approach control), more rationally, effectively can play the potential ability of air traffic control service, under guarantee air traffic safety prerequisite, strive for that flight is normal better.
Practical operation standard dynamic value, compared to the monodrome static criteria transmitted, effectively improves the flow value controlling traffic, decreases airliner delay, improve aircraft punctuality rate.
The invention allows for a kind of dynamic constant value system of ATFM practical operation standard, it comprises,
Traffic flow data storehouse, stores the historical data of the magnitude of traffic flow;
Dynamic value module, obtains the statistical nature of historical traffic flows value from air traffic database, according to the performance management target of ATFM, design dynamic value model;
