Embodiment Construction

[0063] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0064] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0065] figure 1 The implementation process of the method for evaluating the state of an unmanned aerial vehicle provided by the embodiment of the present invention is shown, and the details are as follows:

[0066] Step S101, establishing a state evaluation index mode...

Abstract

The invention is applicable to the technical field of unmanned aerial vehicles (UAV), and provides a state evaluation method and apparatus for UAVs. The method includes the steps of establishing a UVA state evaluation index model, grading UVA state evaluation indexes, establishing a fuzzy determination matrix according to state evaluation indexes of each level, obtaining the constant weight of each state evaluation index according to the fuzzy determination matrix, calculating the grade of membership of each state evaluation index according to a state evaluation index membership grade model, dynamically adjusting the constant weight of each state evaluation index according to the relation between the constant weight and the membership grade of each state evaluation index and corresponding threshold, and determining the UVA state evaluation value according to the membership grade and the variable weight of each state evaluation index. The solving process using weight is more objective, the obtained evaluation result is more practical, and the weight proportionality of each index is more obvious, and actual situation can be objectively reflected.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a state evaluation method and device of an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle is a kind of unmanned aircraft, equipped with autopilot or remote control equipment. It has the advantages of small size, low cost, strong concealment, and convenient use. It is widely used in image reconnaissance, electronic interference, communication relay, It has broad application prospects in various fields such as agricultural plant protection and aerial photography. However, with the continuous improvement of the performance of unmanned aerial vehicles and the continuous increase of system complexity, the problems of reliability, maintainability and maintenance guarantee have become more and more prominent. UAV users often rely on the experience of operators to qualitatively and generally judge the health status of the airc...
