specific Embodiment 1

[0029] Detailed examples of a drone current height

[0030] The drone climbing section needs to be kept within a certain height, thereby improving the safety of drone. Within this height, different height targets (such as higher high objectives) often correspond to higher security.

[0031] According to an embodiment of the present invention, a plurality of specific control targets can be set for a control item for measuring the current height of the drone. For example, for conventional cruise heights 7000 meters, the first height target H 1Can be 7200 meters, the second height target H 2 Can be 7400 meters.

[0032] For the above cruise height H 0 One standard weight value can be set in advance 0 In this way, according to N 0 Then determine the first height target H 1 Corresponding first-order weight value N 1 And second height target H 2 Corresponding first-order weight value N 2 .

[0033] According to an embodiment of the present invention, the first height target H can be det...

specific Embodiment 2

[0061] Specific embodiments two landing gears have been collapsed

[0062] The drone climbing section requires the landing gear that has been collapsed, otherwise the landing gear will seriously affect the aerodynamic performance of the drone, and hinder the further improvement of flight speed.

[0063] According to an embodiment of the present invention, a plurality of specific control targets can be set for control items that have been collapsed by the landing gear of the drone. For example, in consideration of the above-mentioned landing gear, it is determined by multiple cycles, so that different numbers are given to these multiple cycles respectively. For example, the first cycle to the fifth cycle is p 1 , P 2 , P 3 , P 4 And P 5 .

[0064] Assume that the first time the landing gear has been collapsed in the first cycle P 1 Then, the corresponding first-order weight value is n = 100. Similarly, assuming that the landing gear has been collapsed in the third cycle P 3 Then, t...

Abstract

The invention discloses a flight segment control method and device. The method includes determining a plurality of first-order weight values, wherein each first-order weight value is used to indicate whether the current state of the drone satisfies one of a plurality of preset control objectives, wherein the plurality of control objectives are used It is used to measure the control items of the UAV from the first stage of climbing to the second stage of climbing; determine a plurality of second-order weight values, wherein each second-order weight value is used to indicate the credibility of each first-order weight value and according to the multiple A first-order weight value and the plurality of second-order weight values ​​control the UAV to enter the second stage of climbing. The invention controls the UAV to enter the second climbing stage according to the first-order weight value and the second-order weight value, thereby improving the accuracy and reliability of the UAV entering the second climbing stage.

Description

Technical field [0001] The present invention relates to the field of drone control, and more particularly to a flight segment control method and device. Background technique [0002] In recent years, the Unmanned Aerial Vehicle, referred to as a UAV or drone) has become one of the most potential models. Its long-term use, wide use, high cost performance, rich in load and weapons. Using mounted photoelectric load, guided weapons, synthetic aperture radar, communication reconnaissance and other equipment, long-range drones can work in patrol reconnaissance, mineral detection, forest fire prevention, marine monitoring and other fields. [0003] Different from the usual consumer-level unmanned aircraft (DRONE), long-range drones typically fly over 5000m, and the time is over 24 hours and needs to mount more load. Therefore, long-range drones requires higher intensity technology in various aspects of body materials, power systems, flight control systems, and communication systems. [...
