Problems solved by technology

[0005] (2) "Misjudgment" is prone to occur
In fact, since the orientation of the error ellipsoids in space is constantly evolving, it is difficult to predetermine the specific moment when the error ellipsoids touch
Therefore, even if the error ellipsoids of the master and slave aircraft do not intersect at the nominal minimum distance, they may still intersect at a non-minimum distance, and there is still a greater possibility of collision, so this method is prone to "missed judgment"

Embodiment Construction

[0071] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0072] In the present invention, it is assumed that two aircraft are a master aircraft and a slave aircraft respectively, and the two aircraft fly at close range and meet in the air, and the master aircraft and the slave aircraft can exchange roles. Reference coordinate system S xyz The origin of is located at the center of mass of the main aircraft, such as figure 2 As shown, suppose that the flight state (vector) of the slave aircraft relative to the master aircraft is x=[r T v T ], where r is the relative position (a vector), Is the relative speed (a vector).

[0073] Such as figure 1 As shown, a flight anti-collision sensing method includes the following steps:

[0074] Step 1: Initialize the two aircraft flying in the...

Abstract

The invention relates to a flight anti-collision sensing method and system, a storage medium, and equipment, and the method comprises the steps: initializing two aircrafts which meet with each other,and obtaining the initial state information of one aircraft relative to the other aircraft; calculating a relative reachable range of one aircraft affected by the process noise in a given time periodaccording to the initial state information, and determining a no-fly zone of the other aircraft according to the initial state information; and judging whether there is a collision risk between the two aircrafts according to the relative reachable range and the no-fly zone. The method provided by the invention achieves the anti-collision sensing of the aircraft in a three-dimensional space under the basis of consideration to the impact from the initial state error and the process noise, obtains the relative reachable range of one aircraft and the no-fly zone of the other aircraft, so as to judge whether the two aircrafts have the collision risk or not, thereby solving the problems that a conventional method causes judgment leakage and does not give consideration to the size of an aircraft,and improving the anti-collision sensing reliability.

Description

Technical field [0001] The invention relates to the technical field of flight control, in particular to a flight anti-collision sensing method, system, storage medium and equipment. Background technique [0002] Anti-collision issues have always been a technology that has focused on aircraft (aerospace or aerospace). Assume that two aircrafts that meet at close range are the master aircraft and the slave aircraft respectively. Since there are inevitably system uncertain errors in the actual mission, these uncertain errors may directly lead to a collision between the master and the slave aircraft. Anti-collision perception is to integrate navigation error, random disturbance error, relative flight trajectory and other information to quickly assess whether there is a collision threat in the future. Anti-collision perception is the prerequisite to ensure that two aircraft will not collide with each other for a long period of time. [0003] The traditional anti-collision sensing meth...
