Runway subregion intelligent alarm step S103:
The region of setpoint distance threshold value around runway is divided into runway subregion, in runway subregion, based on the intelligence computation method of landing passage, airborne vehicle is alerted, particularly as follows:
Obtain the position data of airborne vehicle；The position data of described airborne vehicle includes altitude information and horizontal location data；
According to predetermined flight posture criteria for classification, it is judged that/landing the state of taking off of airborne vehicle；
Airborne vehicle to landing state, it is determined that the landing point O of airborne vehicle；
With landing point O for initial point, with the direction of the horizontal component in airborne vehicle landing direction for y-axis, to direction, sky for z-axis, to set up O-xyz three-dimensional cartesian coordinate system；Then the coordinate of landing point O is (0,0,0), the coordinate (0, oy, 0) of runway head, and the real-time coordinates of airborne vehicle is that (x, y, h), its initial coordinate entering runway subregion is (x0,y0,h0)；
With landing point O for starting point; a ray is drawn to airborne vehicle; landing passage as this airborne vehicle; this landing passage and runway corresponding with this airborne vehicle and extended line direction thereof become predetermined landing angle q; about the horizontal direction of landing passage, extend predeterminated level tolerance Dl, extend predetermined vertical tolerance Dh up and down in the vertical direction of landing passage, form the protection zone R (x of a cuboidr,yr,zr) ,-Dl < xr< Dl, y0<yr< oy, h1r<zr<h2r, wherein
Real-time coordinates according to airborne vehicle, it is judged that whether airborne vehicle projection on runway is in the scope of the protection zone of cuboid projection on runway；As x<-Dl, x>Dl, y<y0Or during y > oy, airborne vehicle is alerted；

The embodiment of the present invention sets minimum safe altitude based on each subregion that terrain data is alarm region of zones of different, and the airborne vehicle entering this subregion is alerted.
Due in alarm region, except normal airline carriers of passengers, it is likely to that army's boat training aircraft occurs, army's boat aircraft is likely to when practising super low altitude flight trigger alarm conditions, therefore the embodiment of the present invention can also make a distinction by general's aircarrier aircraft, suppress list by arranging alarm and military aircraft is listed in wherein, thus aircraft that army is navigated does not carry out alarming processing and can greatly reduce false-alarm yet.Alarm suppresses list to arrange can adopt secondary code suppression method: each airborne vehicle can be assigned with a secondary code before take-off, the mark of identity is distinguished during as flight, in order to avoid distribution conflict, the secondary code that each regulatory area can be distributed is in the scope of a regulation, also there are differentiation in army's boat and civil aviaton in range of distribution, therefore can suppressing in list, the airborne vehicle of this secondary code section to be added in the alarm of system, the minimum safe altitude alarm that the airborne vehicle in this secondary code section is produced will not provide prompting.Alarm suppresses list method to set up can also adopt Negative Fight Plan flight alarm suppression method: each commercial air flights can a corresponding flight plan, the inside includes the flight number of this flight, type, rise and fall all multi information such as airport, but army's boat or navigation will not issue civil aviaton flight plan, therefore can pass through have Negative Fight Plan to judge whether this airborne vehicle is aircarrier aircraft, thus the airborne vehicle of Negative Fight Plan is not carried out minimum safe altitude alarm prompt.
Common alarm region can adopt mosaic mode or irregular polygon mode to divide, at each subregion, minimum safe altitude is set, but this situation is near runway and inapplicable, because airborne vehicle alarm during landing near runway is difficult to calculate, it is easy to when aircraft takeoff produce false-alarm, some system adopts the mode arranging alarm inhibition zone near runway, minimum safe altitude alarm is not calculated in certain limit around runway, although the false-alarm that so will not produce in the situation of taking off, but minimum safe altitude alarm real during to airborne vehicle landing also can be failed to report, bring potential safety hazard.Therefore the embodiment of the present invention also sets runway subregion, landing state according to airborne vehicle near runway, the intelligence computation method based on landing passage is adopted to carry out intelligent alarm: to judge it is takeoff condition or landing state from the flight posture of airborne vehicle, airborne vehicle for takeoff condition does not carry out minimum safe altitude alarm calculating in runway alarm region, has gone out runway alarm region and has then been calculated by the setting in common alarm region；For the airborne vehicle of state of landing, whether it is in the protection zone of cuboid according to it and alerts.Advantage of this is that, effectively reduce the false-alarm ratio of the airborne vehicle of takeoff condition in runway subregion, can guarantee that again the airborne vehicle of landing state still belongs to the target alerted, and to its alarm mode more intelligent and science, not only give due alarm prompt but also greatly reduce false-alarm.
On this basis, further, the embodiment of the present invention can also include clear for flying height determination step: judges whether airborne vehicle has clear for flying height；For having the airborne vehicle of clear for flying height, during when the minimum safe altitude set in the flying height of airborne vehicle is lower than this subregion and higher than its clear for flying height, airborne vehicle is not alerted；When the flying height of airborne vehicle is lower than its clear for flying height, airborne vehicle is alerted.Sometimes when airborne vehicle is by alerting region, airborne vehicle can be provided clear for flying highly according to practical situation by controller, even if this has highly triggered alarm conditions, airborne vehicle at this altitude without providing alarm prompt, but flying height is once lower than clear for flying height, provide alarm at once.Advantage of this is that, effectively reduce the unnecessary false-alarm ratio for having clear for flying airborne vehicle highly, can guarantee that again and provide due alarm prompt when its flying height is lower than its clear for flying height, it is ensured that its safety.
On the basis of above-mentioned any embodiment, further, the embodiment of the present invention can also include warning information subregion and push step: calculate this airborne vehicle currently affiliated management region according to the position data of airborne vehicle, warning information is sent to the controller in this airborne vehicle currently affiliated management region.The division with each subregion in alarm region that divides in management region is two entirely different things.In practical operation, alarm region is divided into different management regions according to factors such as area size, flight flow process, flight flows, and the management region that oneself is only commanded by each controller is responsible for.Therefore, when airborne vehicle enters alarm region, this airborne vehicle currently affiliated management region can be calculated by information such as the position of airborne vehicle, height and controller's manual operations, warning information is only issued the controller managing region belonging to this airborne vehicle when occurring by minimum safe altitude alarm, and other management region controller can't see this warning information.Thus can avoid controller because other alarms managing regions that system is provided by visual fatigue are paid no attention to, consequently, it is possible to ignore to fall the situation of real minimum safe altitude alarm.
On this basis, further, the embodiment of the present invention can also include subregion and push rate-determining steps: is pushed by subregion and controls switch, opens or closes warning information subregion push function.The difference that thus can require according to control in practical application, pushes control switch by subregion and controls opening or closing of warning information subregion push function.
