Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

1-7, the embodiment of the multi-source sensing detection system for airport surface operation elements of the present invention will be further described.

1, a multi-source perception detection system for airport surface operation elements in this embodiment includes: an aircraft perception detection system 100, a vehicle perception detection system 200, an operator perception detection system 300, an operation risk perception detection system 400, and, Data storage system 500. The aircraft perception detection system 100, the vehicle perception detection system 200, the operator perception detection system 300, and the operation risk perception detection system 400 are respectively connected to the data storage system 500 through electrical signals.

From the perspective of airport surface operation rules and aircraft ground support operation procedures, the multi-source perception and detection system includes two aspects. One is the precise positioning of aircraft elements, vehicle elements, and personnel elements (mainly airport surface operators). And operating situation tracking; one is the mutual perception and detection between aircraft and vehicles.

Specific instructions are given below.

Refer to Figure 2. Fig. 2 is a structural block diagram of an aircraft perception detection system in an embodiment of the multi-source perception detection system for airport surface operation elements of the present invention.

In this embodiment, the aircraft sensing detection system integrates a surface surveillance radar 101, a multi-point positioning system 102, an ADS-B receiver 103, a flight plan data system 104, and a trajectory data fusion processor 105. The surface surveillance radar 101 is a relatively traditional aircraft sensing and detection equipment. It is generally installed on the airport tower to monitor targets in the near-ground range. The surface surveillance radar is more sensitive to weather. There are more false targets due to multipath effects and ground object reflections. There are also blind spots. The multi-point positioning system 102 is an aircraft sensing and detection equipment. Multi-point positioning is based on the signal monitoring of the airborne transponder, and calculates the exact position of the detected aircraft through the time difference between the airborne transponder signal reaching different ground receiving stations. Its positioning accuracy is better than that of the scene. Surveillance radar. The ADS-B receiver 103 directly decodes the ADS-B message information transmitted by the aircraft's onboard equipment, obtains the aircraft's position, speed, identification number and other information, and realizes the perception and detection of the aircraft. Its positioning accuracy depends on the aircraft's own satellites. The positioning accuracy of the navigation and positioning system. For the same scene and the same aircraft, the scene surveillance radar 101, the multi-point positioning system 102, and the ADS-B receiver 103 may generate duplicate targets. The trajectory data fusion processor 105 will perform the process based on the flight plan data system 104 and aircraft trajectory information. Fusion processing, filtering false targets and repeated targets, while reducing the coverage blind area of a single detection system, effectively ensuring the sensing and detection effect of the aircraft on the scene, and transmitting the detection results to the data storage system, the aircraft positioning accuracy can reach 7.5 meters.

Refer to Figure 3. Fig. 3 is a structural block diagram of the vehicle perception detection system in an embodiment of the multi-source perception detection system for airport surface operation elements of the present invention.

The vehicle-mounted satellite positioning device 201 generally uses a Beidou/GPS dual-mode positioning device. When the satellite signal is good, the positioning fusion processor 203 preferentially uses the output result of the satellite positioning device as vehicle positioning information; when the satellite signal is lost, the positioning fusion processor 203 preferentially uses the vehicle positioning information output by the vehicle-mounted inertial navigation device 202. At the same time, due to the vehicle inertial navigation positioning principle, the positioning error increases with time and the long-term accuracy is poor. The positioning fusion processor 203 will also calibrate the vehicle inertial navigation device 202 in a timely manner based on the information of the satellite positioning device. The communication device sends the vehicle positioning result to the data storage system.

The personnel equipment 302 can adopt wearable terminals, such as watches, safety helmets, work clothes, work badges, etc. The wearable terminals are equipped with low-power positioning beacon devices; the personnel equipment 302 can also adopt portable devices. Such as special mobile phones, handheld walkie-talkies, and portable devices have built-in positioning beacon modules. When an operator carries a wearable or portable device and is in the apron area, the wireless communication positioning beacon signal transmitted by the wearable or portable device is received by the base station, which realizes the detection and detection of the personnel, and the positioning accuracy can reach the meter level. The low-power positioning beacon module on the wearable device has good waterproof performance, which is convenient for personnel to ensure operations in the apron area under various weather conditions. The data server and the base station array realize data exchange, store the operator's detection data, and send the data to the monitoring data server of the data storage system.

In particular, the low-power positioning beacon device of the wearable device is installed on unpowered facilities, such as gas cylinder trailers, bulk cargo trailers, etc., and can also achieve high-precision positioning of unpowered facilities to achieve unpowered facilities.

Referring to Figures 5 and 6, there are shown schematic structural diagrams of the operation risk perception detection system in an embodiment of the multi-source perception detection system for airport surface operation elements of the present invention.

In this embodiment, the operation risk perception detection system is used to realize the operation risk perception detection of surface moving targets in the operation process. Specifically, it is to solve the risk perception detection of aircraft and vehicles during the operation of the surface. According to airport operation rules, the operational risks between aircraft and vehicles include two aspects. The first is the danger of approaching or conflicting risks during vehicle driving and taxiing; second, the vehicle is operating close to the aircraft when the aircraft is stationary. , Direct scratching or collision risk during docking aircraft operations.

The onboard ADS-B OUT device 4011A on the aircraft side can automatically broadcast the location, altitude, speed, heading, identification number and other information of the aircraft to the outside. The onboard ADS-B IN device 4011B can receive ADS-B sent by other aircraft and vehicles. OUT information to realize the detection of aircraft and vehicles with ADS-B OUT capability. The ADS-B OUT device 4012A on the vehicle side can automatically broadcast the location, speed, identification number and other information of the vehicle to the outside. The on-board ADS-B IN device 4012B can receive ADS-B OUT information sent by other aircraft and vehicles to achieve ADS-B OUT capable of detecting aircraft and vehicles.

In the specific implementation and application of the present invention, from the perspective of equipment application cost and airport operating rules, all aircraft can be equipped with airborne ADS-B OUT equipment and airborne ADS-B IN equipment, but it is not necessary for all vehicles to be equipped with on-board vehicles. ADS-B OUT equipment and vehicle-mounted ADS-B IN equipment. From the airport operating rules, certain vehicles have the authority to operate on the runway/taxiway and enter the aircraft taxiing area, such as the guided vehicle. The vehicle can be equipped with ADS-B OUT equipment and ADS-B IN equipment at the same time to facilitate aircraft Mutual detection with vehicles; some vehicles usually operate far away from the runway/taxiway, and generally do not enter the aircraft taxiing area, but there may be the possibility of crossing the taxiway. For example, a shuttle bus can only be equipped with on-board ADS-B IN The equipment can receive the ADS-B OUT information sent by the aircraft in real time during the driving process, realize the position and operation situation awareness and detection of the aircraft, and reduce the risk of conflict.

Refer to Fig. 6, which is a structural block diagram of the operation anti-collision risk detection system. It is mainly used for vehicles that need to approach or dock with aircraft for operations, such as food trucks, luggage transfer trucks, platform trucks, etc. During the operation of such vehicles, it is necessary to reduce the risk of collision with the aircraft or other collision risks. The work collision avoidance risk detection system 402 includes an ultrasonic detection device 4021, a video acquisition device 4022, a driver behavior monitoring device 4023, and a communication device 4024. The ultrasonic detection device 4021 can detect the obstacle information around the vehicle, and when the vehicle is docked with the aircraft, it can also accurately detect the docking distance between the vehicle and the aircraft, thereby reducing the risk of collision. The video collection device 4022 is used to collect image information around the vehicle to reduce the blind spot of the driver's line of sight and reduce the risk of collision. The driver behavior monitoring device 4023 is used to monitor driver behavior habits, such as unsafe driving operations such as smoking, making phone calls, and driving fatigue states such as drowsiness and yawn. The communication device 4024 transmits the detection data of the ultrasonic detection device, the video acquisition device, and the driver behavior monitoring device to the data storage system.
