Detailed Description
The following description of the embodiments of the present invention is provided in connection with the accompanying drawings.
The invention discloses an airport flight area traffic crossing occupation conflict early warning method based on multi-source fusion, which comprises the following steps:
s1, predicting a taxi path of an aircraft in an airport flight area based on information of the aircraft;
s2, calculating the predicted arrival time and the predicted departure time of all traffic crossings of the taxiing path obtained by the aircraft through the step S1 to obtain the forbidden time period of the aircraft;
s3, calculating the distance between the current position of the aircraft and all traffic crossings of the taxi path obtained in the step S1;
s4, counting the forbidden time periods of the aircraft calculated in the step S2 of all the traffic crossings to obtain a prediction state diagram of each traffic crossing;
s5, according to the calculation result in the step S3, displaying different colors according to the distance between the aircraft and each traffic crossing, and forming a global traffic crossing current state diagram of the airport flight area; and
and S6, in the step S4, the time of no passing is displayed in red to alarm the staff, in the step S5, the distance between the aircraft and the traffic crossing is less than 150 meters, namely, the traffic crossing is displayed in red in the current state diagram of the global traffic crossing to alarm the staff.
In this step S1, the method for predicting the taxi path of the airport flight area of the airline system is not limited, and the taxi path of the aircraft in the airport flight area may be predicted according to other relevant information such as the flight type and the position information of the aircraft, where the taxi path includes the path information and the start time of the taxi path so as to facilitate the predicted arrival time and the predicted departure time of the aircraft passing through all traffic intersections on the taxi path. The relevant data sources in the embodiment comprise secondary radar, S-mode radar, field surveillance radar, multipoint positioning, ADS-B, flight plan and the like.
The calculation method of the predicted arrival time and the predicted departure time of the aircraft calculated in the step S2 takes the arrival of the nose of the aircraft at the traffic crossing as the predicted arrival time and the departure of the tail of the aircraft from the traffic crossing as the predicted departure time. And the time period between the expected arrival time and the expected departure time is the forbidden time period of the traffic crossing. When the number of the aircrafts is large, the forbidden time periods of all the aircrafts at each traffic crossing need to be calculated.
During taxiing of the aircraft, the step S3 continues to calculate the distance between the current position of the aircraft and all traffic crossings in the taxi path. And step S3, calculating the distances between the current position of the aircraft and all traffic crossings on the taxi path, and combining the calculation results of the multiple aircraft to obtain the real-time distance between each traffic crossing and the multiple aircraft.
The step of S4 is specifically: counting the forbidden time periods of all the aircraft calculated in the step S2 on each traffic crossing to form a prediction state diagram of each traffic crossing, wherein the formed prediction state diagram is shown in figure 2, the number in each square is a time table, the bottom color of each square is the state of the traffic crossing at the time, the red color represents that the traffic crossing is forbidden to pass/the traffic crossing is occupied, and the green color represents that the traffic crossing is allowed to pass/the traffic crossing is unoccupied. The prediction state diagram of the traffic crossing is divided according to minutes, and the prediction state diagram of the traffic crossing comprises the prediction state of at least 60 minutes of the traffic crossing.
The current state diagram of the global traffic crossing formed in step S5 is specifically shown in fig. 3, and the current state diagram of the global traffic crossing includes map information of an airport flight area and current state information of each traffic crossing. When the distance between the aircraft and the traffic crossing is more than 500 meters, the traffic crossing displays green; the distance between the aircraft and the traffic crossing is more than 150 meters, and when the distance is less than 500 meters, the traffic crossing displays yellow; when the distance between the air and the traffic crossing is less than 150 meters, the traffic crossing displays red. The manner of displaying the map information of the airport flight area in the current state diagram of the global traffic crossing is not limited, and preferably, the map of the airport flight area in the embodiment is presented in a manner of a GIS background diagram.
Certainly, when a ground vehicle passes through a traffic crossing in a flight area, accidents such as vehicle anchor dropping, luggage dropping or emergency occupation of a crossing channel by an ambulance/fire truck may occur, and the traffic crossing is in a non-passable state at the moment, and at the moment, a worker needs to manually modify the state information of the traffic crossing so as to alarm the aircraft, so that the aircraft can change a sliding path in time and avoid the non-passable traffic crossing. Meanwhile, in the construction process of the airport, certain traffic crossings in an airport flight area cannot pass due to construction, and at the moment, staff manually adjust the states of the traffic crossings to ensure that the information in the current state diagram of the global traffic crossing and the prediction state diagram of each traffic crossing is accurate.
In addition, the global traffic crossing current state diagram and the current state diagram of each traffic crossing in the embodiment are synchronously transmitted to the air traffic zone management department, the air traffic control department, the airport apron tower control department, the airport operation management department and other units of the airport so as to realize data symmetry among the units, and facilitate ground control of the airport on the air traffic zone.
The above embodiments are only for illustrating the invention and are not to be construed as limiting the invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, therefore, all equivalent technical solutions also belong to the scope of the invention, and the scope of the invention is defined by the claims.
