Embodiment
Install and structural representation at the scene of homeplate runway detection device for foreign matter as shown in Figure 1, in this system, has used two radars to take the photograph equipment mutually with Liang Tai, and every equipment can scan the about 2000 meters highway section of runway.Single radar and picture pick-up device are positioned on the same control tower, and two radars are installed at the homonymy of runway.As shown in the figure, control tower 210 and 220 is located at the same side of runway 400, on control tower 210, is provided with a radar and a picture pick-up device, and the radar on the control tower 210 has fan-shaped radar scanning zone 110; On control tower 220, be provided with a radar and a picture pick-up device, the radar on the control tower 220 has fan-shaped radar scanning zone 120; Overlapping in radar scanning zone 110 and 120, covers the zone of whole runway 400 after two zones superpose fully.
The sweep length of each radar can cover the width of whole runway, in scanning, the angle of pitch is done corresponding algorithm correction and makes radar can cover whole piece runway width scan; During picture pick-up device scanning runway is divided into some frames by length direction, adopts up and down and accomplish the detection to whole runway by the mode of frame scan back and forth, the scanning area 300 among the figure has illustrated that promptly a frame scan wherein is regional; Adopt the scan mode of radar and the relatively independent detection of shooting can improve the efficient of detection and reduce rate of false alarm.
Wherein, radar system is FMCW, and frequency of operation is 35GHz, and operating distance is 1.05km, and bearing accuracy is 3m.Placing two on the whole piece runway gets final product.
Equally; The image analytic degree of each picture pick-up device or image resolution ratio are more than 2,000,000 pixels; Comprise an imaging lens (adjustable focal length scope: 50～2000mm, minimum field angle: be not more than 17 ') and a light compensation equipment (infrared laser compensation at night; Use the invisible light infrared lamp of wavelength＞830nm, can effectively avoid light pollution), also comprise a servo platform (servo platform maximum angular rate: 45 °/s, servo platform orientation bearing accuracy: 1 ').Place two cover picture pick-up devices on the runway, two cover picture pick-up devices are corresponding with two radars respectively, the certain interval runway scope of scanning.
Because detections of radar is relatively more responsive to the material and the shape of detected material, may produce higher wrong report and rate of failing to report to non-metallic objectsit is not a metal object; And that Video Detection identification relies on the extraction of color contrast and effective pixel points is bigger, so the pick-up unit of the mutual cooperation that provides of the utility model can be accomplished detection to the runway foreign matter under the cooperation of radar and picture pick-up device.
In actual the use, radar and picture pick-up device scan the detection foreign matter simultaneously.
If radar is found foreign matter, picture pick-up device stops to detect and preserving current position information, and the positional information of passing back according to radar subsequently removes to observe foreign matter, and passes the image information of foreign matter back.After this process is accomplished, take the photograph the location point continuation scanning that phase equipment turns back to preservation.
Equipment carries out communication through fiber optic Ethernet network and control desk to radar equipment with taking the photograph mutually.
Airfield runway foreign matter (FOD) monitoring radar receives through launching electromagnetic wave and detects and accurate localizing objects position; Be transferred to control desk to data and target location parameter through Ethernet and carry out system synthesis, video system is carried out the tracking and the identification of target according to target position information.
Camera system receives the control information from control end through fiber optic Ethernet, regulates camera angle, focal length, aperture automatically, takes the image of runway foreign matter; When camera system does not receive foreign matter (FOD) information of radar, can runway be scanned according to the setting track of oneself, can produce a warning if detect foreign matter, and current foreign matter pictorial information is sent to workstation.If equipment receives the positional information that radar imports into; Can at first preserve the current position information of picture pick-up device; Trace into the foreign matter position that radar provides subsequently; Catch picture and pass current images information back through optical fiber, after this process was accomplished, picture pick-up device turns back to the position of savepoint to be continued runway is scanned.
Promptly as shown in Figure 2, after the system start-up of whole device, camera system is at first pursued frame and is scanned up and down, and after picture pick-up device detected foreign matter, picture pick-up device was passed the foreign matter picture information back to workstation; If picture pick-up device does not detect foreign matter, radar will begin scanning, when detections of radar behind foreign matter, picture pick-up device correspondingly stop scanning, and the storage current information follow the tracks of foreign matter simultaneously; Whether pass workstation back according to radar or the detected foreign matter information of picture pick-up device and decide and return the picture pick-up device analyzing spot and continue scanning, perhaps after the information of passing back exceeds the time, report to the police.
The airfield runway detection device for foreign matter that the utility model provides possesses radar simultaneously and takes the photograph two kinds of detection modes of equipment mutually; Wherein, radar can adopt the mode of Echo Processing that runway is detected, and picture pick-up device can adopt the mode of image processing that runway is detected; Radar and picture pick-up device are independent to scan detection to runway, independent of master station transmission detection information; Picture pick-up device receives the FOD positional information that radar imports into, can at first preserve the positional information of the current scanning of picture pick-up device, and tracing process is accomplished the position continuation that the back picture pick-up device turns back to savepoint runway is scanned.
