[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] Embodiment 1: This application discloses a method for aircraft safety detection.

[0054] For details, please refer to Figure 1 The present embodiment discloses a method for aircraft safety detection, comprising the following steps:

[0055] Step 101: Obtain a dynamic set of aircraft in an airport flight zone, and model a target aircraft in the dynamic set.

[0056] In the method described in this embodiment, the position information of each aircraft is obtained. The position information may come from a position acquisition device provided on the aircraft, and the position information may specifically include coordinates and wingspan information of the aircraft. The wingspan information is the wingspan of the aircraft wing. In actual work, when performing position acquisition, the aircraft is usually understood as a point. When processing the distance between points, considering the wingspan of the aircraft wing can make the distance more accurate.

[0057] In the method described in this embodiment, the position of the aircraft in the air is not necessarily the same as the position projected on the ground, but there is a certain deviation. Therefore, as an optional method, after obtaining the position information, the elevation information corresponding to the ground coordinates of the aircraft can be used to determine whether the actual position of the aircraft is located in the airport flight area. Then, all aircraft located in the airport flight area are dynamically selected to form a dynamic set, and all aircraft in the dynamic set are used as target aircraft. Among them, the dynamic set indicates that the aircraft in the set are not fixed. When an aircraft is no longer located in the airport flight area, it is deleted from the dynamic set. Correspondingly, when an aircraft enters the airport flight area, it is added to the dynamic set.

[0058] In the method described in this embodiment, when modeling the target aircraft, the maximum distance from the center point of the target aircraft to each vertex can be obtained, and a safety model that can completely wrap the target aircraft is constructed with the maximum distance as the radius and the center point of the target aircraft as the center of the sphere.

[0059] Step 102: Based on the modeling results, the surface operation rules of the airport flight zone and the data information of the target aircraft, the safe distance of the target aircraft is obtained.

[0060] In the method described in this embodiment, the airport flight zone surface operation rules are the business rules stipulated by the airport itself, which include the direction of operation of the aircraft, the distance between two aircraft during operation, etc. For example, a certain airport stipulates that the operation direction of aircraft A is opposite to the operation direction of aircraft B. For another example, a certain airport stipulates that aircraft A and aircraft B must maintain a distance of not less than 500m during operation. Therefore, the airport flight zone surface operation rules described in this embodiment may vary for different airports, and may also vary due to the version of the airport business rules, and its content varies with the airport's business rules. This embodiment does not specifically limit the content of the airport flight zone surface operation rules. If the content is empty, the rules will not be considered.

[0061] In the method described in this embodiment, the data information of the aircraft includes the aircraft model, speed and altitude. After analyzing the airport flight zone surface operation rules, the running direction and / or the distance to be maintained of the target aircraft can be obtained. According to the airport flight zone surface operation rules and data information, the initial safety distance of the target aircraft can be set. Specifically, it can include the initial safety horizontal distance and the initial safety vertical distance.

[0062] In the method described in this embodiment, the minimum spatial distance in the vector direction between the center points of each safety model is calculated. The initial safety distance is combined with the minimum spatial distance to obtain a safety distance. The safety distance in the method described in this embodiment takes into account the initial safety distance and the calculated minimum spatial distance. Among them, as a combination rule, for example, the initial safety distance is that aircraft a and aircraft b must maintain a distance of not less than 500m during operation, and the calculated minimum spatial distance is 200m, then the initial safety distance is given priority, and the safety distance is determined to be 500m. Correspondingly, if the minimum spatial distance is 800m, the minimum spatial distance is given priority, and the safety distance is determined to be 800m. In actual work, there may also be other combination rules. This embodiment does not specifically limit the combination rules here, and it is sufficient to have the effect of comprehensively considering the initial safety distance and the minimum spatial distance.

[0063] Step 103: Based on the modeling result, the dynamic distance between each of the target aircraft is obtained.

[0064] In the method described in this embodiment, the modeling result is used as a point, and the longitude information, latitude information and altitude information of each point can be obtained through the broadcast automatic dependent surveillance system. Based on the longitude information and latitude information, the ground projection distance between the two points is calculated as the horizontal distance, and the difference in the altitude information between the two points is used as the vertical distance. According to the horizontal distance and the vertical distance, the spatial distance between the two points is calculated, that is, the dynamic distance in this embodiment.

[0065] In the method described in this embodiment, the dynamic distance means that the distance may be constantly changing. As time changes, the position of the aircraft may change, and the calculated dynamic distance will also change accordingly.

[0066] As an optional method, the Haversine formula is used to calculate the ground projection distance between two points. The formula is:

[0067]

[0068] Where d1 is the ground projection distance, r is the radius of the earth (about 6371 km), φ1 and φ2 are the latitudes of the two aircraft (converted to radians), △φ is the difference in latitude of the two aircraft, and △λ is the difference in longitude of the two aircraft.

[0069] As an optional method, the spatial distance between two points is calculated according to the Pythagorean theorem, and the formula is as follows:

[0070]

[0071] In the formula, d2 is the spatial distance and h is the vertical distance.

[0072] Step 104: When the dynamic distance is less than or equal to the safety distance, a danger warning message is sent.

[0073] In the method described in this embodiment, the dynamic distance obtained in real time is used to compare with the safety distance. When the dynamic distance reaches the safety distance, a danger warning message can be sent through methods including but not limited to text, voice, warning lights, etc. As an optional method, the danger warning message is used to remind airport control personnel of the impending risk of collision so that airport control personnel can control aircraft in the airport flight zone. As another optional method, the danger warning message may also include control information, that is, a control plan for aircraft in the airport flight zone, to assist airport control personnel in controlling. This embodiment does not specifically limit the form and content of the danger warning message, and it is sufficient to help airport control personnel control aircraft in the airport flight zone.

[0074] The method described in this embodiment only models the aircraft in the airport flight zone, reducing the amount of calculation and the cost of calculation. Analyzing the operating status of real aircraft in a simulated form and monitoring and managing the aircraft can achieve the effect of pre-control. And when calculating the safety distance, the surface operation rules of the airport flight zone are taken into account, which is flexible and portable. At the same time, the dynamic distance between each aircraft is obtained in real time, and the operating status of each aircraft can be continuously monitored. The method described in this embodiment performs real-time safety detection of aircraft. When the dynamic distance is less than or equal to the safety distance, a danger warning message is sent, which can help airport control personnel to timely and accurately command aircraft adjustments, reduce safety risks, ensure the safe operation of aircraft, and also improve the operating efficiency of the airport flight zone, and more perfectly protect the surface safety of the airport flight zone.

[0075] Embodiment 2: This application discloses another method for aircraft safety detection, please refer to Figure 2 The method described in this embodiment introduces the entire process of aircraft safety inspection.

[0076] Step 201: Obtain the location information of the first aircraft and determine whether the first aircraft is located in the airport flight zone. If yes, proceed to step 202. If no, repeat step 201.

[0077] Step 202: Model a first aircraft.

[0078] Step 203: According to the surface operation rules of the airport flight zone and the data information of the first aircraft, the initial safety distance of the first aircraft is set.

[0079] Step 204: Calculate the minimum spatial distance of the first aircraft according to the modeling result.

[0080] Step 205: Determine whether the minimum spatial distance is greater than or equal to the initial safety distance. If yes, proceed to step 206. If no, proceed to step 207.

[0081] In the method described in this embodiment, as an optional method, when the minimum spatial distance is equal to the initial safety distance, the values ​​of the two distances are equal, and the initial safety distance can also be set as the safety distance, which is not specifically limited in this embodiment. Similarly, this step essentially means that this embodiment combines the minimum spatial distance and the initial safety distance to obtain the safety distance. The combination rule for judging the size here is also only an example. In actual use, other combination rules can also be used, which is not specifically limited in this embodiment.

[0082] Step 206: Set the minimum spatial distance as a safe distance.

[0083] Step 207: Set the initial safety distance as the safety distance.

[0084] Step 208: Based on the modeling results, the dynamic distance between the first aircraft and other aircraft in the airport flight zone is obtained.

[0085] Step 209: Determine whether the dynamic distance is less than or equal to the safety distance. If yes, proceed to step 210. If no, repeat step 209.

[0086] Step 210: Send danger warning information.
