Description

A mixed-system airport runway foreign object detection system

technical field

The invention belongs to the technical field of object detection and recognition in the field of image recognition, and relates to a monitoring system for foreign objects on airport runways, in particular to a mixed system airport runway foreign object detection system.

Background technique

Foreign objects on the airport runway (FOD) refer to any objects in the flight area that may endanger the safety of aircraft on the ground, such as stones, metal parts, tapes, plastic products, newspapers, small animals, etc. FOD on airport runways will not only induce air crashes and aircraft damage during takeoff and landing stages, resulting in direct losses such as casualties; it will also cause indirect economic losses and negative impacts caused by flight delays, interrupted takeoffs, and runway closures. According to statistics, the indirect loss is at least 4 times the direct loss. In order to ensure the safe take-off and landing of aircraft on the airport runway and reduce losses, the airport generally conducts manual inspections of foreign objects on the road surface by inspectors on a regular basis. At present, the prevention of foreign objects on the runway mainly relies on the multiple routine inspections of the runway by inspectors in accordance with regulations. Due to the need to close the runway during manual inspections, this greatly reduces the flight capacity. With the number of flights taking off and landing at my country's civil aviation airports increasing year by year, highly automated technical monitoring methods are used to assist or replace manual inspections to improve the efficiency of foreign object inspections on airport runways. Shortening the runway occupancy time has important practical significance for improving the efficiency of airport runway operation.

1. Status quo of automatic FOD detection system

Based on the airport's urgent need for FOD automatic detection technology, the industry uses different technical means to monitor runway surface FOD. The developed FOD automatic detection system can work continuously in real time, to assist or replace the non-contact monitoring method of manual inspection, and improve the inspection efficiency of foreign objects on the airport runway. Shortening the runway occupancy time has practical significance for improving the operating efficiency and safety level of airport runways.

From the perspective of technical means and deployment methods, the current FOD detection technology can be divided into three categories: tower type FOD detection system, side light type FOD detection system and vehicle-mounted system.

1.1 Tower type FOD detection system

The sensors of this type of system are installed on the tower, and the tower is deployed more than 100 meters away from the center line of the runway. The working diagram of the tower system is as follows:

As shown in Figure 1, the deployment diagram of the tower system, point a represents the tower FOD monitoring point. According to the type of sensor, it can be subdivided into two categories: pure optical type and photoelectric hybrid type.

1.1.1 Pure optical FOD detection system

Pure optical FOD detection system. Rely on optical sensors to realize long-distance monitoring of the airport runway area, and find and identify foreign objects through image processing technology. A typical representative is the iFerret system of the Stratech formula. The appearance of its optical monitoring point is Stratech's pure optical FOD system.

1.1.2 Photoelectric hybrid FOD detection system

Photoelectric hybrid FOD detection system. Rely on the millimeter-wave radar sensor to realize long-distance monitoring, discovery and identification of the airport runway area; use the optical sensor to confirm the foreign objects found. Typical representatives are Qinetiq's Tarsier system and Trex's Fodfinder XF series.

1.2 Vehicle-mounted FOD detection system

The characteristic of the vehicle-mounted FOD detection system is that the sensor is installed on the movable vehicle, and during the working process, it moves, scans, detects and cleans at the same time. According to the technical system adopted, it can be divided into: photoelectric hybrid FOD and laser sensor scanning system.

1.2.1 Vehicle-mounted photoelectric hybrid FOD detection system

The typical representative of the vehicle-mounted photoelectric hybrid FOD detection system is Trex's Fodfinder TM series Trex's Fodfinder TM system. It uses a millimeter wave radar sensor and an optical sensor, installed on the top of the vehicle, the millimeter wave radar is used for detection, and the optical camera is used for photo confirmation.

1.2.2 Vehicle-mounted laser scanning FOD detection system

A typical representative of the vehicle-mounted laser scanning FOD detection system is the LFOD system of Pavemetrics. It uses a high-speed camera to obtain a plane picture of the vehicle passing through the road surface area, and then uses laser detection technology to obtain the height of the road surface object, thereby forming a three-dimensional picture of the detected road surface. The optical imaging device and the laser emitting and receiving device are installed at the rear of the vehicle. When the system is working, the high-speed camera takes pictures, the laser beam continuously scans the runway pavement, and receives the laser reflected from the pavement, using the signal arrival time difference.

1.3 Side light FOD detection system

According to the existing data, the side light system can also be divided into two types of side light electric hybrid and pure optical systems.

1.3.1 Side light photoelectric hybrid FOD detection system

Its characteristic is that the sensor is installed on the base integrated with the runway edge lights, and its communication and power supply modules are placed in the same space (light barrel) as the runway edge lights, as shown in Figure 2. The schematic diagram of the deployment of the edge light FOD detection unit is as follows: b It represents the edge light FOD detection unit, and its typical representative is the Fodetect system of Xsight Company.

1.3.2 Edge light pure optical FOD detection system

At the same time equipped with infrared auxiliary lighting system. Its coverage diagram is shown in Figure 3.

2. Hybrid airport runway foreign object detection system

According to the actual application of various types of FOD detection systems, the existing FOD detection systems have the following problems:

2.1 Problems existing in the existing system

(1) The three types of FOD detection systems have their own advantages and disadvantages: in the actual deployment process, the installation position of the tower FOD system is affected by the electromagnetic compatibility evaluation and the protection area of the navigation station, and the height of the tower is affected by the airport flight. The elevation of the restricted surface of obstacles in the area and the occlusion of bird nets make the system performance not optimal; the side light photoelectric hybrid detection system is installed close to the runway and has good detection performance, but the cost of large-scale deployment is extremely high, and the number of sensor nodes increases. It is easy to lead to an increase in the overall failure rate; the vehicle-mounted FOD detection system still needs to close the runway when it is working, which does not effectively increase the flight throughput rate.

(2) The probability of occurrence of foreign objects in different areas of the airport runway is different, and the safety levels of different stages are also different during the flight take-off and landing process. During the deployment process of the existing FOD detection system, the situation in different areas of the airport runway is not considered in a targeted manner, so the overall performance of the system is not optimal.

(3) The existing FOD detection system adopts a single type of sensor deployment method in the sensor deployment process, such as: Trex, Qinetiq, Stratech's pure tower FOD detection system, Xsight pure edge light FOD detection system. However, when the above-mentioned detection system was installed and deployed, it did not address the specific detection requirements of the airport runway. Considering the deployment cost of the detection system, the sensors were selectively deployed, resulting in the installation of the detection system failing to achieve a balance between cost and system performance.

(4) The design concept of the existing FOD detection system focuses on the detection, discovery and cleaning of foreign objects in the airport runway area, which belongs to the category of passive prevention. The impact of foreign objects in areas other than the runway (taxiways, apron) on the safety of runway operations has not been fully considered. However, according to statistics, some of the sources of foreign matter in the runway area of the airport come from the apron and taxiways. Therefore, in order to improve the foreign object prevention level in the airport runway area, it is necessary to eliminate the influence of foreign objects from the apron and taxiway in time.

Contents of the invention

In order to achieve the stated purpose, the present invention proposes a mixed-system airport runway foreign object detection system, which includes: a tower-type optical detection device, an edge-light photoelectric hybrid detection device, a solid-state edge-light detection device, a data processing module, a foreign object Detection and fusion module, display module, control module, and foreign object positioning guidance module, of which:

The side tower type optical detection device is installed and deployed on one side of the runway for monitoring the second safety level area of the runway;

The light-type photoelectric hybrid detection device is installed at the same site as the runway side lights, and is used to monitor the first safety level area of the runway;

The solid-state side light detection device is installed and deployed at the intersection of runways and taxiways to prevent runway intrusion and foreign objects from entering the runway;

The data processing module is connected with the corresponding tower-type optical detection device, side light photoelectric hybrid detection device, and solid-state side light detection device, and receives data from the tower-type optical detection device, side light photoelectric hybrid detection device, solid-state side light detection device, etc. The image and radar data of the lamp-type detection device are analyzed, the format is unified, reorganized, coded and sent;

The foreign matter detection and fusion module is connected to the data processing module, receives the data processed by the data processing module, performs foreign matter detection on this basis, and performs data fusion on the detection results;

The display module is connected to the foreign object detection fusion module, receives and displays the detection fusion result from the foreign object detection fusion module;

The control module is connected with the corresponding display module, tower-type optical detection device, side light photoelectric hybrid detection device, and solid-state side light detection device, receives control instructions from the display module, and controls the tower-type optical detection device, side light Lamp-type photoelectric hybrid detection device and solid-state edge light detection device are used to confirm the detection results;

The foreign matter location guide module is connected with the display module, receives foreign matter detection information from the display module, and guides the staff to accurately arrive at the place where the foreign matter occurs.

The beneficial effects of the present invention are reflected in the following aspects:

(1) In view of the advantages and disadvantages of the existing tower system, side light system, and vehicle-mounted mobile system in terms of technology and cost, it is proposed to comprehensively deploy tower type optical detection devices and side light photoelectric hybrid detection devices And solid-state side light detection device, optimize the deployment position of the above-mentioned detection device, and build a multi-system FOD detection and monitoring system.

(2) According to the operating characteristics of the airport runway and the occurrence of foreign objects on the airport runway, a targeted solution for the level-by-level monitoring of the runway, taxiway and contact road area according to the safety level has been proposed, which has improved the safety prevention level of the foreign object on the airport runway .

(3) In the FOD monitoring process of the existing tower system, side light system, and vehicle-mounted mobile system, the focus is on the detection, discovery and cleaning of foreign objects in the airport runway area, ignoring the impact of foreign objects from taxiways and aprons on the airport. For the impact of the runway area, it is proposed to add a solid-state side light detection device for monitoring intersections on the basis of the original tower type and side light sensors, so as to realize the expansion of the FOD monitoring area and detect foreign objects from taxiways and aprons. Early warning reduces the interference of FOD to the airport runway area from the source.
