Abstract
The invention relates to an aviation sector capacity control method based on a two-dimension timeslice set. Supposing that n routes passed through a same sector, the first route point of each route entering into the sector is defined as an intersection point of the route and the sector, a same time axis containing a plurality of referential timeslices arranged according to time sequence is set for each intersection point, and the time axes corresponding to intersection points jointly form the two-dimension timeslice set for indicating the sector. Corresponding sector capacity for each time window is set according to flow restriction information of different time windows in the two-dimension timeslice set, and time intervals allowing different aircrafts to pass by each intersection point are set respectively. The aviation sector capacity control method controls flight amount from partial single route point, and controls sector capacity from an overall perspective. Conduction of single point flow control restriction along routes and increasing of time intervals are prevented.
Description
Technical field
The present invention relates to civil aviaton's flow control technique, particularly relate to a kind of aviation sector capacity control method based on two-dimensional time sheet group.
Background technology
Along with the sustained and rapid development of AIRLINE & AIRPORT, air traffic growth is swift and violent, and the crowding phenomenon of airport, spatial domain and Route Network node is serious, and air route blocks up, airliner delay outstanding problem, has become the hot issue of social extensive concern.
The flow control methods of current appearance be substantially all foreign trail interval (MIT) control method, but, the effect that this control method combines with domestic practical application scene is unsatisfactory, this is because: MIT control method mainly achieves the Separation control of the upper aircraft of a line (single air route) and aircraft, because the object of reference (that is: aircraft) in this algorithm is dynamic change, therefore the area (as: America and Europe) that spatial domain can use (aircraft can be gone off course arbitrarily and convert height layer) is flexibly adapted to, by adopting in this way, when aircraft can be diversion when convergent point runs into conflict, but for requiring compared with for the area (as: China) in strict accordance with Route reform, cannot freely by being diversion, going off course and convert means mitigate collisions highly, thus it is more to conflict when causing air route to converge, therefore need strictly to control the generation that the way point moment avoids conflict, and MIT control method is less for the dirigibility removing this conflict, therefore the result of use of flow control is unsatisfactory at home.In addition, flow control domestic is at present conceived on single way point more, easily produces along air route conduction, disadvantage raised without restriction.And due to domestic airspace anxiety, can not use flexibly, the flow restriction of single way point often easily causes local in spatial domain busy and the problem of local free time.Therefore, flow control is carried out compared to single way point, more should be conceived to whole control sector that (control sector is the base unit of air traffic control, generally air traffic control is divided into area control district or terminal (entering near) regulatory area two or more part, and each part is called a control sector) volume controlled.But, the domestic control method also not using sector capacity (the flight quantity that namely can receive in control sector unit interval window) at present, and be only sector capacity is monitored and assesses, and this monitoring and assessment are a kind of real-time monitoring and assessment afterwards, can not control sector flow in advance, the actual service condition in spatial domain under normality condition can only be analyzed, form experience value, as the customization foundation of the reasonable normality capacity in sector, namely once certain sector capacity has exceeded the working load of controller, there is potential safety hazard, controller will send flow-control information to adjacent sectors, require to expand MIT, thus reach the object reducing sector capacity.
In view of the foregoing, the method that current needs adopt rational mathematical physics modeling and Computer Simulation to combine, under the different service condition of the spatial domain units such as airport, complicated sector, busy air route and under the comprehensive condition of all kinds of restriction, effectively control flight flow.

In like manner, suppose that aircraft F02 enters sector SH01 at 10:01 through intersection point P2, after having flown in sector 3 minutes, go out sector SH01; Aircraft F03 enters sector SH01 at 10:02 through intersection point P3, goes out sector SH01 after having flown 4 minutes in sector; Aircraft F04 enters sector SH01 at 10:04 through intersection point P4, goes out sector SH01 after having flown 2 minutes in sector, then the occupancy of each aircraft on each time shaft can be as shown in Figure 2.
Step S5, whether the time interval corresponding between the entry time sheet judging the flight number being marked with different aircraft in the time shaft in described sector corresponding to same intersection point is not less than the time interval arranged in described step S3, if not, then perform step S6, if, whether the quantity then judging to be arranged in the time shaft in described sector corresponding to all intersection points the flight number of the different aircrafts that all reference times of described time window same time, sheet marked is not more than the sector capacity that described step S2 is arranged, if not, then perform step S6, if, then step terminates,
Such as, in embodiment three, according to above-mentioned steps S2, suppose that the sector capacity in the SH01 of sector from 10:00 to 10:10 in this time window is 4 framves, namely to represent that in the SH01 of sector from 10:00 to 10:10 in this period of time, aircraft quantity per minute is 4 framves to the maximum, and, according to above-mentioned steps S3, suppose that the different aircraft elapsed times that the intersection point P1 of sector SH01 allows are spaced apart 2 minutes, the different aircraft elapsed times that intersection point P2 allows are spaced apart 3 minutes, and the different aircraft elapsed time intervals that intersection point P3 and P4 allows are worthwhile is 1 minute, simultaneously, suppose that aircraft F01 enters sector SH01 at 10:00 through intersection point P1, sector SH01 is gone out after having flown in sector 3 minutes, aircraft F02 enters sector SH01 at 10:02 through intersection point P1, sector SH01 is gone out after having flown in sector 2 minutes, aircraft F03 enters sector SH01 at 10:05 through intersection point P1, sector SH01 is gone out after having flown in sector 4 minutes, aircraft F04 enters sector SH01 at 10:01 through intersection point P2, sector SH01 is gone out after having flown in sector 2 minutes, aircraft F05 enters sector SH01 at 10:04 through intersection point P2, sector SH01 is gone out after having flown in sector 3 minutes, aircraft F06 enters sector SH01 at 10:00 through intersection point P3, sector SH01 is gone out after having flown in sector 2 minutes, aircraft F07 enters sector SH01 at 10:01 through intersection point P3, sector SH01 is gone out after having flown in sector 2 minutes, aircraft F08 enters sector SH01 at 10:03 through intersection point P3, sector SH01 is gone out after having flown in sector 2 minutes, aircraft F09 enters sector SH01 at 10:02 through intersection point P4, sector SH01 is gone out after having flown in sector 3 minutes, aircraft F10 enters sector SH01 at 10:06 through intersection point P4, sector SH01 is gone out after having flown in sector 4 minutes, thus, according to the two-dimensional time sheet group that the method for above-mentioned steps S4 can obtain as shown in Figure 3.
As seen from Figure 3, the surrounding time interval that aircraft F01, F02, F03 enter sector SH01 by intersection point P1 is respectively: aircraft F01 and F02 interval 2 minutes, aircraft F02 and F03 interval 3 minutes, that is, the entry time sheet of the flight number (" F01 ", " F02 ", " F03 ") of different aircraft is marked with (namely in time shaft corresponding to intersection point P1, sheet reference time corresponding to time 10:00,10:02 and 10:05) between the corresponding time interval be all more than or equal to the different aircraft elapsed time intervals that intersection point P1 allows, namely 2 minutes, in like manner, the time interval that aircraft F04, F05 enter sector SH01 by intersection point P2 is 3 minutes, that is, the entry time sheet of the flight number (" F04 ", " F05 ") of different aircraft is marked with (namely in time shaft corresponding to intersection point P2, sheet reference time that time 10:01 and 10:04 is corresponding) between the corresponding time interval equal the different aircraft elapsed time intervals that intersection point P2 allows, namely 3 minutes, aircraft F06, F07, F08 enters sector SH01 by intersection point P3, and the surrounding time interval that aircraft F09 and F10 enters sector SH01 by intersection point P4 is respectively: aircraft F06 and F07 interval 1 minute, aircraft F07 and F08 interval 2 minutes, aircraft F07 and F09 interval 1 minute, aircraft F09 and F08 interval 1 minute, aircraft F08 and F10 interval 3 minutes, aircraft F09 and F10 interval 4 minutes, intersection point P3, the flight number (" F06 " of different aircraft is marked with in time shaft corresponding to P4, " F07 ", " F08 ", " F09 ", " F10 ") entry time sheet (namely, time 10:00, 10:01, 10:02, sheet reference time that 10:03 and 10:06 is corresponding) between the corresponding time interval be all more than or equal to time interval of the worthwhile setting of intersection point P3 and P4, namely 1 minute.As can be seen here, each aircraft F01-F10 meets through the time that each self-corresponding intersection point P1-P4 enters sector SH01 the different aircraft elapsed time intervals that each intersection point allows.
But, equally can be as can be seen from Figure 3, frame number except aircraft different in this minute of 10:02 in the SH01 of sector be 5 framves (namely, aircraft F01, F02, F04, F07 and F09) beyond, the frame number of the different aircrafts of the other times from 10:00 to 10:10 in this time window is all less than or equal to 4 framves, therefore, as a whole, do not meet the requirement of " in this time window, sector capacity is 4 framves from 10:00 to 10:10 ", thus need to perform following steps S6.
Step S6, adjusts described aircraft enters described sector time through corresponding described intersection point, and returns the described step S4 of execution.
Such as, in above-described embodiment three, the time that aircraft F09 enters sector SH01 through intersection point P4 is adjusted, the time delay making it enter sector 2 minutes; Then return and perform above-mentioned steps S4, to obtain two-dimensional time sheet group as shown in Figure 4.As seen from Figure 4, after adjustment, in the SH01 of sector in this minute of 10:02 the frame number of different aircraft be 4 framves (namely, aircraft F01, F02, F04 and F07), therefore, meet the requirement of " in this time window, sector capacity is 4 framves from 10:00 to 10:10 ", simultaneously, aircraft F08, F09 and F10 enter interval time (aircraft F08 and the F09 interval 1 minute of sector SH01, aircraft F09 and F10 interval 2 minutes) also meet time interval of the worthwhile setting of intersection point P3 and P4, namely 1 minute.So far, above-mentioned steps can be terminated.
In sum, all aircrafts can be made not only to meet entry time space requirement by the present invention, also can meet sector capacity requirement, thus flight flow in conservative control spatial domain.
