摘　　要：根据无人机载化学气体报警器可行性及主要战术指标,以氨气为例,进行仿真分析和现场试验,研究无人机采样杆特征变化对检测氨气精度的影响。通过仿真分析确定无人机采样杆在杆长为1.8 m,杆径为3 mm时的检测效果最佳。在此情况下将采样杆前置悬停,经过现场试验得出检测精度高达44.12%,验证了在特定杆长情况下无人机载化学气体探测的可行性。本文采用仿真分析和现场测试对无人机载化学气体探测可行性进行研究,可为化学毒剂检测提供参考和工程应用。In view of the high toxicity,strong volatilization and fast action of chemical agents,which can cause large casualties at very low concentrations,on-site detection of chemical agents is very important.According to the feasibility and main tactical indicators of the UAV-borne chemical gas alarm,the simulation analysis and field test were carried out by taking ammonia as an example,and the influence of the characteristic change of the UAV sampling rod on the detection of ammonia content was emphatically studied.Through simulation analysis,it is preliminarily concluded that the UAV sampling rod has the best effect on gas detection when the rod length is 1.8 m and the rod diameter is 3 mm.In this case,the sampling rod is hovered in front,and the detection accuracy is as high as 44.12%after field tests,which verifies the feasibility of unmanned aerial vehicle chemical gas detection under specific pole length characteristics.In this study,simulation analysis and field tests were used to analyze and verify the feasibility of unmanned aerial vehicle(UAV)chemical gas detection,which provided a useful reference and engineering application direction for the detection of chemical agents.
