无人机立体风场测试实验及效果分析

摘要

无人机喷雾以其灵活、便捷等特点，在植保领域受到广泛关注，并在病虫害防治上取得新进展。但是，目前关于无人机喷雾的研究，主要集中在无人机控制装置，防漂移药剂，喷雾效果的地面检测上，对于无人机自身参数变化和立体风场对于喷雾效果的影响研究较少。本文综述了雾滴沉积受立体风场的影响，同时列举了目前立体风场的影响因素。研究表明，喷雾效果受飞行参数、自然因素、喷雾雾化设备和喷雾方式等多因素影响，但风速是影响雾滴沉积效果的最显著因素，因此在做出采用无人机施药决策时，需要综合考虑多方面的因素，尤其是立体风场对雾滴沉积的影响。

Test Experiment and Effect Analysis of UAV Stereo Wind Field

ABSTRACT

UAV spray has been widely concerned in the field of plant protection because of its flexibility and convenience, and has made new progress in pest control. However, at present, the research on UAV spray mainly focuses on UAV control devices, anti drift agents, and the ground detection of spray effect. This paper summarizes the influence of three-dimensional wind field on droplet deposition, and lists the influencing factors of current three-dimensional wind field. The study shows that the spray effect is affected by many factors such as flight parameters, natural factors, spray atomization equipment and spray mode. However, wind speed is the most significant factor affecting droplet deposition effect. Therefore, when making UAV decision making, we need to consider many factors, especially the influence of three-dimensional wind field on droplet deposition.

1. 课题研究目的和意义

随着可持续发展在世界范围内的影响越来越显著，人们对农林业机械的要求越来越高，促进了农林业机械水平的提高。但是在植保方面，尤其是喷洒化学药剂防治病虫害仍是以手工、半机械化操作为主，这种治理方式已完全不能满足现代农林业的规模化中只需要；另一方面，喷药人员中毒事件时有发生。为了促进农林业发展和作业人员安全，在喷洒化学药剂防治病虫害方面必须加快推进喷药技术机械化，满足作业要求，提高作业效率，达到作业目的。
