Study on Applicability Evaluation System of UAV in Soybean Plant Protection Operation

Through the research and analysis,the applicability evaluation system of soybean plant protection UAV was constructed,and three indexes for evaluating the applicability of soybean plant protection UAV were put forward:uniform speed fluctuation,spray settlement and uniformity of spray,and all the performance indexes were quantified.This paper analyzes the weight of three performance indexes of soybean plant protection UAV applicability evaluation,and uses the comprehensive weight analysis method composed of Delphi method and analytic hierarchy process,as well as yaAHP weight analysis software.It is found that spray deposition is the most important factor affecting the applicability of soybean plant protection UAV.hen,according to the principle of efficacy coefficient method,the efficacy coefficient function is constructed for three indexes,so as to set the scoring standard of performance indexes,and determine different calculation formulas for different performance indexes.It is convenient to evaluate the applicability of soybean plant protection UAV.In order to ensure the applicability evaluation system of soybean plant protection UAV is scientific and reliable,the applicability of an eight rotor test aircraft is evaluated by using this evaluation method,and the result is consistent with its practical performance.This study provides a theoretical basis for farmers to choose and use soybean plant protection UAV reasonably.
