Accompanying drawing explanation
Below with reference to accompanying drawing, embodiment of the present invention are described, wherein:
Fig. 1 is the block diagram of detection warning system of state of boarding a plane according to the runway shown in embodiment of the present invention.
Detailed description of the invention
The board a plane embodiment of detection warning system of state of runway to the present invention is described in detail below with reference to accompanying drawings.
Runway is the region of strip on airport, is used for for aircraft takeoff or landing.Runway material can be Colophonium or concrete, or grass, soil or the rubble ground flattened, it is also possible to is the water surface.
Large airport generally has a plurality of runway.These runways can be named according to their magnetic azimuth, and its azimuth specifies the use direction of this runway, the i.e. direction of motion of airborne vehicle during duty runway simultaneously.The principle of name is to take the front two number at Magnetic Orientation Of Runways angle, it is possible that refer to, with " 09 runway ", the runway that azimuth is 94 degree (eastwards)；The runway of 168 degree is referred to " 17 runway ".Due to the possible two-way use of runway, because using direction change, the azimuth that runway is corresponding also changes, so general runway has two Numeral name.Above-mentioned azimuthal variation is 180 degree, as long as so 18 will be added deduct on the Numeral name of one of them runway, just can obtain the title of runway other direction, such as " 12 runway " rightabout is " 30 runway ".If airport has more than an identical runway in direction, can after numeral in addition " L ", " C ", " R " distinguish, represent respectively a left side (Left), in (Center) and right (Right).Such as " 15L ", " 15C ", " 15R " refer to three parallel to each other, azimuth is the runway of 150 degree.
Determining wing airborne vehicle and helicopter to be generally required for when taking off and land carrying out against the wind, this is the ground velocity in order to reduce airborne vehicle on the premise of ensureing to have enough lift as far as possible, i.e. relative to the movement velocity on ground, in order to reduce the coasting distance on runway.So according to local long-term meteorological condition, some airport can have a plurality of not parallel runway, in order to can use under the different wind directions of Various Seasonal；For only runway or the airport of a plurality of parallel runways, its runway heading is generally consistent with the direction of local prevailling wind.Landing airdrome length decide to a certain extent can the size of landing aircraft and type, this is also had an impact by the intensity of runway pavement, runway width and aerodrome elevation.In general, type is the biggest, and the landing airdrome length needed for landing is the longest.
There are various mark and mark on runway, generally include: runway title, runway centerline, runway threshold, landing point, access area, runway boundary line etc..International Civil Aviation Organization specifies, the mark of runway must be white, and can improve display effect by the way of adding black surround for light colour runway.These marks and mark for providing the reference of takeoff and landing for aircraft pilots, and meanwhile, airdrome control personnel watch the takeoff and landing situation on runway attentively by photographic head, in order to when aircraft exception, provide warning message for airport and aircraft pilots.But, above-mentioned mark and mark need aircraft pilots's artificial cognition, the image of photographic head shooting to need airdrome control personnel manually to aircraft recognition and tracking, and data provide speed relatively slow, and automaticity is the highest, excessively rely on artificial.

nullDescribed microprocessor and left side object-recognition unit、Left side target tracking unit、Right side object-recognition unit、Right side target tracking unit、Front side object-recognition unit、Front side target tracking unit、Rear side object-recognition unit、Rear side target tracking unit and storage device connect respectively，To left side object-recognition unit、Right side object-recognition unit、Average in the aircraft that front side object-recognition unit and rear side object-recognition unit export respectively current location in runway，Result after averaging is as aircraft physical location，Judge whether aircraft physical location boards a plane in entry region at runway，If，Then send aircraft row alarm signal by mistake，Judge whether the time of staying exceedes the plane reservation time of staying to aircraft based on aircraft physical location，If it exceeds，Then send aircraft and be detained alarm signal，The movement locus of aircraft on the left of judging respectively、The movement locus of right side aircraft、Whether the front side movement locus of aircraft and the movement locus of rear side aircraft mate with plane reservation movement locus，Movement locus at left side aircraft、The movement locus of right side aircraft、When in the front side movement locus of aircraft or the movement locus of rear side aircraft, existence is not mated with plane reservation movement locus，Send track and do not mate alarm signal；
Display device, connects described microprocessor with display with aircraft row alarm signal by mistake, aircraft is detained alarm signal or track does not mate the word information warning that alarm signal is corresponding, and based on aircraft physical location Dynamic Announce aircraft and the dynamic analog figure of runway；
Audio alert equipment, connects described microprocessor to play with aircraft row alarm signal by mistake, aircraft is detained alarm signal or track does not mate the audio alert file that alarm signal is corresponding；
Wireless Telecom Equipment, connects described microprocessor with by with aircraft row alarm signal by mistake, aircraft is detained alarm signal or track is not mated word information warning corresponding to alarm signal and is sent to the mobile terminal of airport management personnel by cordless communication network；
Wherein, left side target tracking unit, right side target tracking unit, front side target tracking unit and rear side target tracking unit all use target tracking algorism based on template matching.
