中文摘要
植保无人飞机有更好的地形适应性和高效的低空喷雾能力,在农业生产中有较大的应用前景。研究植保无人飞机喷洒雾滴的沉积特性(分布均匀性和穿透性),不仅对新型农药制剂及植保无人飞机喷洒装备的研发具有重要的科学意义,同时也对农药高效安全使用具有实际的指导意义。本项目在已有植保无人飞机喷洒影响雾滴沉积特性单一或几个独立因素研究基础上,通过植保无人机喷洒流场室内模拟测试系统对温湿度及自然风的模拟,融合作业参数、环境条件、作物冠层特性与旋翼气流等,开展多因素影响雾滴沉积特性的深入研究,探明影响农药雾滴沉积因素的主效应与互作效应,并对影响因素进行统计分析,量化试验参数,建立能够反映多因素内在联系的雾滴沉积特性评价分析数学模型,并在此基础上研究提出科学、有效的农药最佳雾量沉积评估方法。该研究可为我国植保无人飞机作业标准的制定,同一尺度下作业机具的检测与评估,以及喷洒系统的改进与提升提供必要的科学依据。
英文摘要
Plant Protection Unmanned Aerial Vehicles (UAV) has better terrain adapt ability and efficient ultra-low altitude spray capacity, which has a larger application prospects in agricultural production. The studies on the droplet deposition of UAV spraying are not only important for the development of new type pesticide and application equipment ,but also important for guiding the safe and high efficient application of pesticide in the field. Based on the existing research for the influence of single or several independent factors of plant protection UAV on.droplet deposition characteristics, the following studies were carried out in this paper. Firstly, the simulation of plant protection UAV spray flow field was studied. The temperature, humidity and crosswind were preciously simulated by using indoor simulation test system. Then combine operating parameters, environmental conditions, crop canopy characteristics and rotor airflow, the influence of multi-factors on the droplet deposition was studied. The statistical analysis of influence factors was used to obtain the main effect and interaction effect of pesticide droplet deposition. Finally, test parameters were quantified, and the mathematical model of droplet deposition characteristics was established, which can reflect the intrinsic relationship of multi-factors. Based on this analysis a scientific and effective evaluation method was put forward in this paper. The research can provide the necessary scientific basis for the establishment of operation standard for UAV in China, the testing and evaluation of the operating equipment at the same scale, and the promotion and improvement of the spraying system.
