Problems solved by technology

[0003] However, the shape of the electronic fence and the number of inflection points have great uncertainty and irregularity. At the same time, due to the randomness of the drone's aerial position and the diversity of tasks, the frequent changes and complexity of the new waypoint sequence in the dynamic route planning process are greatly increased. To a certain extent, if the traditional array is used for processing, the data processing efficiency will be greatly reduced

Embodiment Construction

[0045] We will further illustrate the present invention below in conjunction with accompanying drawing (as figure 1 shown):

[0046] A highly deterministic data structure design method for an airborne dynamic electronic fence, comprising the following steps:

[0047] 1. Select the data structure of the doubly linked list to model the electronic fence

[0048] (When calculating and processing the electronic fence, for the inflection point of the irregular polygon, only two inflection points adjacent to the inflection point need to be considered; at the same time, since the characteristics of the restrictive and refusal fences are just opposite, in order to reduce Algorithm complexity,) Here, a doubly linked list is used to model the electronic fence (the schematic diagram is as follows figure 1 shown), and modeled counterclockwise for restrictive fences and clockwise for denying fences. Among them, the elements contained in a single node are as follows:

[0049] 1) Longitud...

Abstract

The invention belongs to the technical field of aviation, and particularly relates to a high-determinacy data structure design method of an airborne dynamic electronic fence. The method comprises thefollowing steps: 1) modeling the electronic fence by using a two-way linked list data structure, solving the problem of algorithm heterogeneity of different types of electronic fences, and reducing the modeling complexity; and 2) a linked list being used for designing dynamic route planning, the data processing efficiency being improved, and the contradiction between dynamic address allocation ofthe linked list and airborne fixed addressing being solved by setting a buffer area in advance. The technology is already used on a certain type of unmanned aerial vehicle, design and implementation of electronic fence modeling and dynamic airway planning functions can be effectively supported, meanwhile, the code quantity is greatly reduced, and the operation efficiency is remarkably improved. Simulation calculation, virtual flight and on-board loop tests prove that the technology can ensure normal and efficient operation of the electronic fence function of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a highly deterministic data structure design method for an airborne dynamic electronic fence. Background technique [0002] UAV electronic fence technology can effectively ensure that UAVs have the ability to automatically avoid no-fly areas in actual combat applications. Since the terrain of the no-fly zone is often random and irregular, a series of irregular polygons are often used to represent the electronic fence. According to the purpose of the electronic fence, there are generally two types: the restricted type that prohibits flying out and the refusal type that prohibits flying in. [0003] However, the shape of the electronic fence and the number of inflection points have great uncertainty and irregularity. At the same time, due to the randomness of the drone's aerial position and the diversity of tasks, the frequent changes and complexity of the new waypoi...
