Description
Technical field
The invention belongs to civil aviaton's detection device technology field, more particularly to a kind of foreign body detection system for airfield runway and inspection
Survey method.
Background technology
During Aerodrome Operations, because aircraft frequently rises and falls, the influence of external environment condition in addition, therefore on airfield runway always
There are some exotics, such as crushed stone, metallic element, the block rubber to come off on aero tyre, these exotics are also referred to as different
Thing, it is necessary to be purged in time, otherwise can damage airborne vehicle.Detected at present frequently with foreign body detection system for airfield runway different
Thing.
In foreign body detection system for airfield runway, the scanning device for finding foreign matter generally includes millimetre-wave radar, can
See light picture pick-up device, infrared image pickup device, Laser Scanning Equipment etc., at present more typical airfield runway foreign bodies detection in the world
System has 4 kinds：It is the Tarsier systems of Britain's exploitation, the FODetect systems of Israel's exploitation, Singapore's exploitation respectively
IFerret systems and the FOD Finder systems of U.S.'s exploitation.
The Tarsier systems of Britain's exploitation are the Tarsier1100 of research and development of being received a mandate by Qinetiq companies of Britain
(t1100) foreign body detecting system, the system operating frequency are 94.5GHz, and radar system is continuous wave frequency (FMCW), has thunder
Up to detection range is long, wave beam is narrow and the characteristics of high resolution, the minimum dimension that the system can detect foreign matter is 20 millimeters, and energy
The foreign matter detected is accurately positioned.
The FODetect systems of Israel's exploitation are developed by the Xsight companies of Israel, and the system is by 77GHz millimeter waves
Radar and picture pick-up device composition, multiple road faces monitoring unit (SDU) are separately mounted on the runway edge lights of diverse location, each
SDU is scanned to the region near runway center line marking, after finding airfield runway foreign matter, can be sent out immediately to airdrome control personnel
Go out warning message, inform the accurate location and discovery time of airfield runway foreign matter.Then, equipment can further camera lens, there is provided machine
The video image of field runway foreign matter, after finding airfield runway foreign matter, sensor can lock the position of the foreign matter, to help airport
Personnel take foreign matter away.The minimum dimension that system can detect foreign matter is 25 millimeters, and at night, laser designator association also can be used
Help and take airfield runway foreign matter away.
U.S.'s FOD Finder systems are a set of mobile monitoring systems developed by Trex Enterprises companies of the U.S.,
It may be mounted at the roof of vehicle.The system is made up of monitoring system and daemon software processing system, can detect foreign matter most
Small size is 25 millimeters.Monitoring system uses 78-81GHz millimetre-wave radars, high-precision GPS positioning system and shooting system
System, radar scanning speed are 30 beats/min, and radius of investigation is 200 meters, and in a radome of roof, vehicle is to reach
When dynamic, system scans the region of front part of vehicle, and provides radar and vision signal to airport controllers.Equipped with can be with vehicle
The device of airfield runway foreign matter is picked up according to system indicating position.Once airfield runway foreign matter is removed, the photograph loaded on in-car
Chance is put on record to fragment photograph, and airport control field personnel can also stick bar code to keep a record to airfield runway foreign matter, record simultaneously
Information will be stored in system database by internet.
The iFerret intelligent video detection systems of Stratechsystems companies of Singapore exploitation are by being run on airport
The video camera of advanced high-resolution function is installed at spacing intervals on road, thus detects and recognize that airfield runway is different automatically
Thing, and complicated image processing software can be directed to the illumination of change and pavement conditions make appropriate adjustment.It was found that airport is run
After road foreign matter, system can amplify the image of object, provide the user with the realtime graphic of fragment, allow user to see the thing of discovery
Product.The minimum dimension that the system can detect foreign matter is 20 millimeters, but is applied when night, rainy days and low visibility
There is certain limitation.
