An embodiment of the invention discloses a spraying stability augmentation method and device for a fire-extinguishing unmanned aerial vehicle. According to the technical scheme, the recoil parameter produced by the current fire-extinguishing unmanned aerial vehicle for the spraying fire-extinguishing operation and the wind parameter of the current operation site are determined, the recoil parameter and the wind parameter are input into a preset ANSYS-based stress simulation model, the stress parameter of the current fire-extinguishing unmanned aerial vehicle is determined, the stress parameteris input into a preset stable control output model, and the channel control quantity corresponding to the fire-extinguishing unmanned aerial vehicle is output and acts on the corresponding control channel. With the adoption of the technical means, the stability of the fire-extinguishing unmanned aerial vehicle during performing of the fire-extinguishing operation can be augmented, the influence caused by operation site factors on the fire-extinguishing agent spraying accuracy can be avoided, and the fire-extinguishing operation efficiency of the fire-extinguishing unmanned aerial vehicle isimproved.
本申请实施例公开了一种灭火无人机的喷射增稳方法及装置。本申请实施例提供的技术方案,通过确定当前灭火无人机进行喷射灭火作业产生的后坐力参数和当前作业现场的风力参数,将后坐力参数和风力参数输入预先设置的基于ANSYS的受力仿真模型,确定当前灭火无人机的受力参数,将受力参数输入预先设置的稳定控制输出模型,输出灭火无人机对应的通道控制量,将通道控制量作用于对应的控制通道。采用上述技术手段,可以增加灭火无人机执行灭火作业时的稳定性,避免作业现场因素影响灭火剂喷射的准确度,提升灭火无人机的灭火作业效率。
