Description

SYSTEM FOR COLLECTING FOD IN AIRPORT MOVEMENT AREA

The present invention relates to a system for detecting and collecting foreign matter in a moving area where an airplane travels from an airport to a runway.

The airport is a facility that has facilities and functions necessary for the air transportation of passengers and cargo, and enables the takeoff and landing of aircraft.

In order to take off and land the aircraft, a runway is provided, and the aircraft moves along the moving area between the passenger's seat and the runway.

However, if there are foreign objects on the runway or in the moving area, the safety of the aircraft traveling at a high speed and large size may be problematic, and the damage to property and human life may also be a concern.

In other words, foreign matter in the moving area may cause a tire to fly or damage the aircraft due to impact, which may be a threat to the safety of the aircraft.

Since the airport does not have access to the moving area by the vehicle while the aircraft is moving, the permission of the control tower is obtained using a short interval of the aircraft stoppage time, and the visual inspection is periodically performed by the inspection vehicle.

Domestic airports are inspected four times a day, and for one run, three runways and six runways are inspected, which usually takes about two hours.

In this case, if a debris from a preceding aircraft damages a trailing aircraft due to no real-time monitoring of the occurrence of foreign matter, it could lead to a fatal accident.

In addition, in the case of visual inspection, it is entirely dependent on human ability, and there are limitations in the case of low visibility, nighttime, and bad weather conditions.

In some airports, foreign objects are detected using optical cameras, but there are difficulties in real-time surveillance or foreign matter location detection in heavy rain, snowfall, and fog.

In addition, even in the case of detecting a foreign object by a mobile device equipped with a radar device in a vehicle, the detection function of the non-metallic foreign substance is deteriorated and the visual effect is limited.

Also, when the inspection vehicle collects foreign matter, it takes a lot of time because the vehicle must be stopped and manpower must be collected directly, which is not suitable.

The matters described in the background art are intended to aid understanding of the background of the invention and may include matters which are not known to the person of ordinary skill in the art.

These fixed type detectors are fixed around the runway and the platform is constructed as a structure that can withstand strong winds and is designed so that the steel structure does not resist the collision when the aircraft collides.

The fixed platform is designed to be secure against static load, live load, jet-blast load, wind load and earthquake load. The support bolt is designed as a fuse bolt so that the structure does not resist the collision with an airplane.

In other words, it is designed to meet the ICAO Part 6 FRANGIBILITY standard so that the structure can fall over by itself.

The fixed platform is a fixed platform steel structure in the aerodrome runway. It serves as a tower which enables the radar sensor module and EO (IR Laser light)

An EO (IR Laser Light) camera is installed under the radar dome at the top, and the EO camera is configured to rotate 180 degrees or 360 degrees to perform airside surveillance at the airport.

At the bottom of the platform, a radar and a camera system sensor module rack are installed, and the sensor module rack communicates with the integrated operation system by optical cable or wirelessly.

The fixed EO system is equipped with a center optical camera, and one IR laser light camera is installed on each side for night vision and low vision.

The images scanned by these radar, electro-optical camera and IR Laser Light are transmitted through the sensor module rack to the integrated operation system through the image processing according to the weather information and day and night illumination.

In this way, it is possible to accurately collect the foreign substances in accordance with the situation, so that the foreign matter can be collected.

The integrated operation system receives FOD and provides FOD detection information to the operator through a pattern recognition and data convergence process.

The camera is installed as a PTZ (Pan-tilt-Zoom) module so that the shaking caused by external factors such as wind is minimized.

In addition, special wavelength band penetration filters are installed to detect FOD even in the night, snow, rain, and fog.

Therefore, FOD is detected in real time while driving on the runway or aircraft moving area. When FOD is found, FOD is automatically collected through the collection unit on the rear side of the vehicle, and the collection of the FOD is checked through the rear camera to prevent any trouble.

A mobile control module installed in a system rack collects and controls information of each sensor and devices, and performs communication with the integrated operation system.

In addition, the mobile network switch installed in the system rack transmits communication data for each device such as a radar sensor processor, a control module, an EO sensor processor, a rear camera PC, a console PC, a back camera, a Wi-Fi, And the like.

The mobile radar sensor module consists of a radome, a radar scanning unit, a radar sensor processor and an interface unit.

It analyzes the detected foreign matter information through the radar sensor processor and transmits the information detected by the radar sensor processor. Thus, it is possible to scan and detect foreign matter by the radar even when moving along the vehicle.

In this way, not only foreign matter detection by the fixed type detection device but also multi-substance detection by the mobile type detection device and the mobile type detection device itself can acquire the detection information by scanning the plurality of different characteristics, It enables accurate and real-time collection of foreign matter by accurately detecting foreign matter.

In addition, the moving EO (IR Laser Light) camera is installed in the upper position of the moving platform, the PTZ that acquires the image, and the EO (IR Laser Light), which detects the FOD in the runway, Sensor processor.

The portable battery pack is a device for supplying power to the system rack and the collection device.
