Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in more detail.
Refer to Fig. 2 and a kind of optimization method for effectively reducing short-term flight collision alarm false-alarm provided by the invention is shown
Embodiment, include the step of this method embodiment：
Step S1：The protection zone of an airborne vehicle is calculated the multidimensional scene of flight posture according to airborne vehicle, when another boat
Pocket enters the protection zone and produces track flight collision alert, obtains triggering the airborne vehicle pair of alarm conditions；
Step S2：By the airborne vehicle for meeting triggering alarm conditions to being permitted with reference to its corresponding flight plan using vertical direction
Can flying height, flight posture release that alarm, alarm inhibition zone, secondary code, flight plan, control sector be inside and outside, retrieval boat
Mark data separation mode is detected one by one, and wherein one of differentiation mode detects the track flight collision alert for false-alarm i.e.
Termination detection simultaneously judges the alarm for false-alarm, and each of which, which distinguishes mode, can not all detect that the track flight collision alert is
False-alarm then judges the alarm for effectively alarm.
It is described below and the multidimensional scene of flight posture is calculated according to airborne vehicle, the specific implementation of detection flight collision alarm
Example：
Refer to Fig. 3 and flying scene schematic diagram between airborne vehicle pair is shown, there is shown with：Two airborne vehicle relative flight fields
Scape, the tracking scene that two airborne vehicles fly in the same direction, the parallel flying scene of two airborne vehicles, two airborne vehicle cross flying fields
Scape.
Refer to Fig. 4 and show that airborne vehicle pair is calculated to the multidimensional scene of flight posture based on the airborne vehicle in the present invention
Flight path triggering alarm conditions embodiment 1, set polynary alarm parameter to include：
θ is the course angle of two frame airborne vehicles；
d1It is that two airborne vehicles meet to trigger the relative warning distance that collision alert need to meet during relative flight situation；
d2It is that two airborne vehicles meet to follow that triggers that collision alert needs meet during flight posture to follow warning distance；
d3It is that two airborne vehicles meet to trigger the parallel warning distance that collision alert needs meet during parallel flight posture；
d4It is to intersect the warning distance on the horizontal plane in alarm.
The multidimensional scene of flight posture is calculated based on the airborne vehicle step of the airborne vehicle pair of triggering alarm conditions
Suddenly include：
Step S21a：Obtain the flight path of current time unit airborne vehicle pair and the boat of next chronomere's airborne vehicle pair
Mark；The route projection to both vertically and horizontally；Obtain the flight path one of next chronomere's airborne vehicle pair
As in a very short chronomere, it is rectilinear flight that can regard aircraft as, so according to the flight path information of current time unit,
The information such as flight path information, the speed of aircraft of a upper chronomere, may infer that the flight path information of next chronomere.
Step S21b：According to airborne vehicle to flight path corresponding in current time unit, future time unit in vertical direction
Any one difference in height, acquisition meet perpendicular separation alarm conditions；
Step S21c：Meet to hand in the horizontal direction according to the flight path of current time unit, future time unit airborne vehicle pair
Fork flying scene, relative flight scene, flying scene, parallel flying scene are followed, and according to setting according to two airborne vehicles
The course angle theta of polynary alarm parameter, relative warning distance d1, follow warning distance d2, parallel warning distance d3Calculate each
The protection zone of airborne vehicle egg type, obtain the warning distance d on horizontal plane4, judge to work as according to the warning distance on horizontal plane
Preceding chronomere, future time unit airborne vehicle pair flight path, obtain horizontal alarm conditions.Refer to Fig. 6 and solid line bar is shown
Egg type protection zone of the present invention is represented, Fig. 6 dotted portions show prior art ellipse protection zone, shown from Fig. 6
Prior art ellipse protected area be SPrior art area=π × d4×d3, the present invention can be considered that 2 half elliptics are superimposed
Protection zone area SbqIt is expressed as：
SArea of the present invention=Sbq=π × (d2+d1)×d3/ 2,
Because of d4=d1>d2, so d4>(d1+d2)/2, obtain SPrior art area>SArea of the present invention, so clearly showing ellipse in Fig. 6
The volume of protection zone is more than the volume of egg type protection zone in the present invention, it can be seen that the present invention is not influenceing aviation
Optimization has obtained a kind of protection zone of similar egg type also smaller than ellipse in the case of device safety, due to egg type protection zone
Domain is small and greatly reduces the generation of false-alarm.
According to airborne vehicle to meeting the multidimensional scene detection aviation of perpendicular separation alarm conditions and airborne vehicle to flight posture
The flight path of device pair meets the horizontal alarm conditions, then track flight conflict is effectively alarm, is unsatisfactory for the horizontal alarm bar
Part is then that track flight conflict is false-alarm.
When two airborne vehicle spacing distances are identical, opposite flight, which is met, to take time most short, and flying to meet in the same direction is taken
Between it is most long, parallel flight will not then meet.So alarm conditions set three respectively in same level by three cases above
The different alarm parameters of kind, the embodiment are calculated according to practical flight situation, are formed in the plane one also smaller than ellipse
Protective, reduce protection in the case where not influenceing safety than forming the method for circular protective using a kind of alarm parameter
Scope, therefore greatly reduce the generation of false-alarm.
The scene simplification for simultaneously computationally alerting all short-term flight collisions is two kinds of situations：It is parallel alarm scene and
Non-parallel alarm scene.A set of alarm method is used under parallel alarm scene, it is non-parallel to alert under scene according to two frame airborne vehicles
The rational horizontal plane of course angle dynamic calculation on warning distance to reduce the generation of false-alarm.Carrying out non-parallel scene announcement
During alert calculating, both relative velocities should be considered by after the velocity projections of two frame airborne vehicles to same direction.Both relative velocities
Bigger, then easier to be dangerous close, the warning distance on its horizontal plane should be bigger；Both relative velocities are smaller, then are less susceptible to
Close, the warning distance on its horizontal plane should be smaller.And both relative velocity and its course angle have obvious relation.
Now to how to judge that the flight posture of target is described specifically, wherein airborne vehicle A course is represented with a, aviation
Device B course represents with β, the course angle between two airborne vehicles with θ=| alpha-beta | to represent, if θ>180 °, θ is used
(180- | alpha-beta |) is represented：
1) the airborne vehicle relative flights of two.Airborne vehicle A and airborne vehicle B course angle theta=180 °, such as the first in Fig. 3
Situation.
2) airborne vehicles of two follow flight.Airborne vehicle A and airborne vehicle B course angle theta=0 °, such as second of feelings in Fig. 3
Condition.
3) the parallel flight of the airborne vehicles of two.0 ° of airborne vehicle A and airborne vehicle B course angle<θ<10 ° or 170 °<θ<
180 °, the 4th kind of situation as shown in Figure 3.
4) the airborne vehicle cross flyings of two.10 ° of airborne vehicle A and airborne vehicle B course angle<θ<170 °, such as in Fig. 3
Three kinds of situations.
After classifying to the various situations of the flight posture of airborne vehicle, it is also necessary to clearly relative, follow, parallel and horizontal alarm
Meaning that parameter represents and it is relative, follow, parallel three parameters set the rule for needing to follow in specific application.
1) is with respect to warning distance d1Meet the phase that triggering collision alert need to meet during relative flight situation for two airborne vehicles
To warning distance, as shown in the first situation in Fig. 5；
2) follows warning distance d2Meet to follow for two airborne vehicles and trigger what collision alert needs met during flight posture
Warning distance is followed, as shown in second of situation in Fig. 5；
3) the parallel warning distance d of3Meet to trigger what collision alert needs met during parallel flight posture for two airborne vehicles
Parallel warning distance, as shown in the 4th kind of situation in Fig. 5；
4) intersects the warning distance d on the horizontal plane in alarm4, as shown in the third situation in Fig. 5；On horizontal plane
Warning distance d4Tried to achieve by formula, the warning distance on relative, parallel and intersection alarm horizontal plane is normalized
Description：
As can be seen from the above equation：
(1) when two frame airborne vehicle course angle thetas be 0 when,
d4=d2
(2) when two frame airborne vehicle course angle thetas be 180 when,
d4=d1
That is, with respect to alarm scene and follow the spy that alarm scene is actually intersection alarm scene in the present invention
Example.
The relative warning distance, the setting for following warning distance, parallel warning distance parameter：According to residing for airborne vehicle
Flight level, different alarm parameters can be typically set, as airborne vehicle is entering near field, general flying speed is small, corresponding to accuse
Alert parameter can also set less than normal, and if airborne vehicle adjusts region in area, because flying speed is larger, corresponding alarm parameter is also provided with
It is bigger than normal；During two airborne vehicle relative flights, speed of related movement is that two airborne vehicle speed are added, and flight phase is followed with two airborne vehicles
It is that two airborne vehicle speed differences are compared to movement velocity, moves identical flying distance, the time used in relative flight is many less, but
No matter being which kind of flight posture, the reaction time for leaving controller for is certain, so, generally set relative alarm away from
Warning distance is followed from being greater than；Parallel warning distance is the distance of two airborne vehicles in a parallel direction, the setting of the parameter
The minimum parallel flight interval that needs to meet with reference to two airborne vehicles is generally required to control.
Now by airborne vehicle to illustrating the inventive method than place that prior art more optimizes exemplified by following flying scene：
Assuming that existing level warning distance, which sets MaxS, is set to 50km, i.e. airborne vehicle is adjusted the distance to be started to alarm in 50km；
The inventive method according to the flight posture of airborne vehicle pair in addition to face warning distance is set to MaxS as 50km, navigate by increase
The following distance MinS of pocket pair is 40km；
Current time unit, a upper chronomere are set as 1s, i.e. each second goes to monitor the flight path information of airborne vehicle pair；
Setting airborne vehicle follows flight to A, B, and at a distance of 50km (B preceding, A is rear), A, B flying speed Va are A and B
200m/s, B flying speed are 150m/s, and A, B speed difference V are 50m/s.
Now A, B trigger alarm in the prior art, set current time as T0；
The time of fire alarming T1 of the present invention is T0<=T1<T0+ (MaxS-MinS)/V, i.e. T0<=T1<T0+(50000-
40000)/50, in the case where airborne vehicle does not change to flight posture, the present invention can compare prior art from the foregoing
The time in nearly 200 seconds evening, such as the flight posture of airborne vehicle pair has the trend (B machines accelerate or A machines slow down) of separation during this period,
Alarm will not then be produced.
The alarm distance S of the present invention is MinS<S<=MaxS
Effective alarm is sent when the time is to T+200, effective warning information includes alarm height, course angle, follows announcement
Alert distance, airborne vehicle adjust to positional information, velocity information, ground staff according to warning information.
Compared with prior art, warning distance calculates according to the flight path information of airborne vehicle pair, and warning distance reduces, and protects
Reduce false-alarm on the basis of card safety.
Detect the embodiment 2 of the track flight collision alert：
The specific steps of detection track flight collision alert are distinguished using clear for flying height (CFL) to be included：
Step S22a：Obtain the flight path of current time unit airborne vehicle pair and the boat of next chronomere's airborne vehicle pair
Mark；
Step S22b：Judge to have triggered the airborne vehicles of alarm conditions to one of be provided with clear for flying height and permitting
Flying height is flown, then track flight conflict is false-alarm；Clear for flying height is not set or without flight in clear for flying
Highly, then track flight conflict is effectively alarm.
Airborne vehicle must fly in level altitude layer when flat winged, rather than arbitrarily flight, one between two adjacent height layers
As spacing be 300 meters.Assuming that vertical height alarm spacing parameter is 450 meters between two airborne vehicles of default, but as long as
Controller specifies clear for flying height to a certain airborne vehicle, even if the flying height makes to hang down between airborne vehicle and other airborne vehicles
Straight interval<450 meters trigger alarm conditions, are also considered as being that controller confirms that the spy of potential safety hazard will not be produced under special circumstances
Different processing mode, alarm will not be shown, once airborne vehicle is not held in clear for flying altitude, rise or fall
Gesture, alarm are shown at once.Airborne vehicle A is flat winged in 7800 meters of height layers, and airborne vehicle B is begun to decline from 8400 meters, then system is at this
Aircraft drops to 8250 meters and meets just provide alarm during horizontal range alarm conditions.If controller have input boat in system
Pocket B CLF is highly 8100 meters, represents that comprehensive many factors at that time are judged controller, it is believed that now navigate
Pocket B meets alarm conditions between the altitude will not cause potential safety hazard, system although to calculate two airborne vehicles, but
Also alarm prompt will not be provided；And continue to decline once having passed through 8100 meters of allowable height during airborne vehicle B declines, system
Collision alert prompting is provided at once.
It is the instruction progress by traffic lights under normal circumstances, as long as but having under special circumstances just as the traffic on ground
Traffic police commands, it should and it is preferential with the instruction of traffic police, it can also be passed through in the case of red light
Detect the embodiment 3 of the track flight collision alert：
After alarm produces, the specific steps bag of alarm detection track flight collision alert is released according to the flight posture
Include：
Step S23a：Obtain a upper chronomere, the flight path of current time unit airborne vehicle pair；
Step S23b：A upper chronomere, current time unit are judged to flight path to the airborne vehicle for having triggered alarm conditions
The flight posture of airborne vehicle pair, although standoff distance also in the range of alarm, but as long as being away from flight posture and meeting setting
Alarm revocation distance, then ahead relieving track flight collision alert；The flight path of the airborne vehicle pair is remote flight posture, and
And the alarm revocation distance of setting is not met away from distance, then confirm track flight conflict for effectively alarm.
Assuming that the parameter of default is relative flight warning distance 50km, and releasing warning distance 30km after conflict, two
Airborne vehicle relative flight on sustained height layer, collision alert is produced during at a distance of 50km, controller is immediately to airborne vehicle to entering
Coordination Treatment is gone, two airborne vehicles of commander change course and flown respectively towards two exactly opposite directions, on two airborne vehicles
Pilot when completing this operation, airborne vehicle to the distance between be 20km, although airborne vehicle is to being in remote flight state
Gesture, but between distance there was only 20km, less than after conflict release warning distance 30km, now flight collision alarm will not be released from still
It is so effectively alarm；Airborne vehicle in continuing to fly away from flight posture, during at a distance of 30km can ahead relieving alarm, and without etc.
In away from also just releasing alarm at a distance of 50km after flight posture.
Detect the embodiment 4 of the track flight collision alert：
The specific steps of track flight collision alert are detected in the alarm inhibition zone according to intelligent decision on airdrome scene
Including：
Step S24a：Obtain the flight path of current time unit airborne vehicle pair；
Step S24b：Airborne vehicle alarm inhibition zone information is obtained, by the way that the boat of the airborne vehicle pair of alarm conditions will have been triggered
Mark is compared with alarm inhibition zone information, and the flight path of any one airborne vehicle compares in alarm inhibition zone successfully then confirms boat
Mark flight collision is false-alarm, and the flight path of airborne vehicle pair all compares unsuccessful in alarm inhibition zone, confirms that track flight conflict is
Effectively alarm.
Spacing distance of the airborne vehicle when airdrome scene is parked or is slided is significantly smaller than the parameter that alarm is set, therefore in machine
Field scope can typically set an alarm inhibition zone, and the aircraft in alarm inhibition zone does not alert, and alarm inhibition zone is only limitted to field
Airborne vehicle on face, alarm is just also calculated in the range of inhibition zone at last once leaving ground and taking off, therefore key is that
How to judge in the alarm inhibition zone that aircraft is in scene.Meet that following three condition intelligent decisions go out airborne vehicle and pressed down simultaneously
In the range of area processed and in scene：
(1) height, the height that system uses around airport are QNH (QNH) height, and the height is phase
For sea level, thus airport height above sea level less than sea level area this be highly probably a negative value, in high altitude localities
Even if the height shown on runway is likely to be several kms；Therefore it is the airborne vehicle for receiving system in the judgement of height
After highly carrying out QNH amendments, compared with aerodrome elevation, error thinks not leave ground within 20 meters.
(2) scope, system can receive and handle simultaneously multichannel monitoring signal, due to all kinds of supervision equipment purposes, function with
And the geographical position of installation is different, obtained information has deviation, so employing the multi-source monitoring optimal card of data changeable weight
Kalman Filtering blending algorithm positions to airborne vehicle, pays the utmost attention to the signal source of field prison radar and scene multipoint positioning, with reference to
The data obtained from secondary radar and ADS-B calculate the geographical position of airborne vehicle, judge whether the horizontal model in alarm inhibition zone
In enclosing.
(3) speed, the speed of airborne vehicle is extrapolated according to the offset in airborne vehicle geographical position in continuous multiple cycles, it is small
Think not take off in 50KM/H.
Detect the embodiment 5 of the track flight collision alert：
The specific steps of detection track flight collision alert are distinguished according to the secondary code to be included：
Step S25a：The airborne vehicle for having triggered alarm conditions is compared to flight path, obtains the secondary code letter of airborne vehicle pair
Breath,
Step S25b：If judging that the secondary code information of airborne vehicle pair belongs to the scope that secondary code alarm suppresses,
Then confirm that track flight conflict is false-alarm；If at least one airborne vehicle is not belonging to the scope that secondary code alarm suppresses,
Confirm track flight conflict for effectively alarm.
Detect the embodiment 6 of the track flight collision alert：
The specific steps of track flight collision alert are detected according to the flight plan to be included：
Step S26：The airborne vehicle for having triggered alarm conditions is compared to flight path, obtains the flight plan letter of airborne vehicle pair
Breath；
Step S26b：Airborne vehicle is judged to whether having flight plan information, if airborne vehicle without corresponding to all flying
Plan, then confirm that track flight conflict is false-alarm；If at least one airborne vehicle has corresponding flight plan, flight path is confirmed
Flight collision is effectively alarm.
In regulatory area, in addition to normal commercial air flights, it is likely that army's boat training aircraft or navigation operation occurs
Aircraft, army's boat aircraft is usually to be flown into team, and spacing distance is significantly smaller than civil aviaton's alarm parameter；Navigation aircraft presses the plan of oneself
Route flies, and may also produce each other dangerous close.Therefore aircarrier aircraft and non-aircarrier aircraft are made a distinction, not to the non-people
The aircraft that navigates carries out alarming processing also can significantly less false-alarm.Suppressing non-aircarrier aircraft alarm mode typically has two kinds：
(1) secondary code suppresses, and each airborne vehicle can be allocated a secondary code before take-off, during as flight
The mark of identity is distinguished, in order to avoid distribution conflicts, the secondary code that each regulatory area can be distributed is as defined in one
In the range of, also there are differentiation in army's boat, navigation and civil aviaton in range of distribution, therefore can be suppressed with this method.Army's boat training flight
When one group of aircraft secondary code it is usually continuous, the scope A0001-A7777 such as suppressed from secondary code alarm only need to be
