Embodiment
Below with reference to accompanying drawings the board a plane embodiment of detection alarm system of state of runway of the present utility model is elaborated.
Runway is the region of strip on airport, is used for for aircraft takeoff or landing.Runway material can be pitch or concrete, or the grass of flattening, soil or rubble ground, can be also the water surface.
Large airport has many runways conventionally.These runways can be named according to their magnetic azimuth, and the user that its position angle has indicated this runway is simultaneously to, the i.e. direction of motion of aircraft when duty runway.The principle of name is to get the front two number at Magnetic Orientation Of Runways angle, so may refer to the runway of position angle as 94 degree (eastwards) taking " 09 runway "; Refer to the runway of 168 degree with " 17 runway ".Due to the two-way use of runway possibility, because user is to variation, the position angle that runway is corresponding also changes, so general runway has two digital titles.Above-mentioned azimuthal variation is 180 degree, so as long as the numeral of one of them runway is added deduct to 18 nominally, just can obtain the title of runway other direction, for example " 12 runway " reverse direction is " 30 runway ".Exceed a runway that direction is identical if airport has, can be after numeral in addition " L ", " C ", " R " distinguish, represent respectively left (Left), in (Center) and the right side (Right).For example " 15L ", " 15C ", " 15R " refer to three parallel to each other, position angle is the runway of 150 degree.
Determine wing aircraft and helicopter conventionally all needs to carry out against the wind in the time taking off and land, and this is the ground velocity in order to reduce aircraft under the prerequisite that ensures enough lift as far as possible, i.e. the movement velocity on relative ground, to reduce the coasting distance on runway.So according to the long-term meteorological condition of locality, some airport can have many not parallel runways, to can use under the different wind directions of Various Seasonal; For the airport of only having a runway or many parallel runwayss, its runway heading is conventionally consistent with the direction of local prevailing wind.Landing airdrome length is determining size and type that can landing aircraft to a certain extent, and intensity, runway width and the aerodrome elevation of runway pavement also have impact to this.In general, type is larger, and the required landing airdrome length of landing is also just longer.
On runway, there are various mark and mark, generally include: runway title, runway centerline, runway threshold, landing point, access area, runway boundary line etc.International Civil Aviation Organization's regulation, the mark of runway must be white, and can improve display effect by the mode that adds black surround for light colour runway.These marks and mark are used to aviator that the reference of takeoff and landing is provided, and meanwhile, airdrome control personnel watch the takeoff and landing situation on runway attentively by camera, so that in the time that aircraft is abnormal, for airport and aviator provide warning message.But above-mentioned mark and mark need aviator's artificial cognition, the image that camera is taken needs airdrome control personnel manually to aircraft recognition and tracking, and data provide speed slower, and automaticity is not high, too relies on artificial.
