Problems solved by technology

If the take-off segment is not transferred to the climb segment, but to the leveling segment, then the control target is completely different, which may cause a serious flight accident

Embodiment Construction

[0032] The specific implementation steps of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] figure 1 It is a schematic flow chart of the UAV flight stage conversion method of the present invention. like figure 1 As shown, set A and B as two adjacent flight stages in the flight stage of the UAV. To complete the conversion from flight stage A to flight stage B, the flight stage conversion process is as follows:

[0034] (1) Judging whether the current flight stage is A, if it is A, continue to judge whether all the conditions required to convert A to B are met; Convert to B;

[0035] (2) If all the conditions required to convert A to B can be met at the same time, then the counter + 1, and continue to judge whether the counter is greater than or equal to M; if all the conditions required to convert A to B cannot be satisfied at the same time, the flight phase remains as A, where all the conditions required to tran...

Abstract

The invention provides a conversion method for flight phases of an unmanned aerial vehicle. The conversion of the flight phases are defined based on the characteristic that the flight phases are divided according to flight course, so that the flight phases are sequentially converted, thus avoiding random conversion; a compound condition judgment is made according to the feature of each flight phase, thus avoiding the danger of single condition conversion; directed at random jump, successive judgments are made to judge whether conditions are satisfied, thus reducing the occurrence of dangerous little probability events. By this method, the safety and reliability of conversion of the flight phases of the unmanned aerial vehicle are improved, harm caused by phases conversion is avoided, thus to improve flight safety.

Description

technical field [0001] The invention relates to a flight stage conversion method applied to an unmanned aerial vehicle, belonging to the field of unmanned aerial vehicle flight control. Background technique [0002] In order to carry out more accurate and reliable control, people often artificially divide the flight process of the aircraft into different flight stages, and the control strategies and goals corresponding to each flight stage are different. UAVs with autonomous control function usually use the flight stage as a symbol to control the whole flight process of the aircraft in stages. Each flight stage can be automatically converted according to the pre-designed conversion conditions, and the UAV will automatically follow each flight. Stage corresponding control, and finally realize the automatic control of the whole process. [0003] The division of flight phases is determined by the designer according to the different control strategies designed. In the past, th...
