The invention relates to a long-endurance floating unmanned aerial vehicle capable of adjusting buoyancy based on load, and belongs to the technical field of unmanned aerial vehicles. In order to solve the problem that the cruising ability is weak when the unmanned aerial vehicle is loaded, the unmanned aerial vehicle mainly comprises a buoyancy cabin body used for being filled with mixed gas of air and light gas in a specific proportion; the power system comprises a plurality of unmanned aerial vehicle power units, and the unmanned aerial vehicle power units are all connected with the buoyancy cabin body; the loading platform is hung below the buoyancy cabin body through a lifting rope; the tension sensor is configured to obtain the tension on the lifting rope; the gas proportion adjusting system is used for adjusting the proportion of air and light gas in the buoyancy cabin body; and the controller is configured to determine the total load according to the tension value obtained by the tension sensor, and control the gas proportion adjusting system to adjust the gas proportion in the buoyancy cabin body based on the total load, so that the buoyancy provided by the buoyancy cabin body is balanced with the total load.

    本发明涉及一种基于载重调整浮力的长续航浮空无人机,属于无人机技术领域。本发明为了解决无人机载重时续航能力弱的问题,方案主要包括:浮力舱体,用于充入特定比例的空气和轻型气体的混合气体;动力系统,包括若干无人机动力单元,所述无人机动力单元均与所述浮力舱体连接;装载平台,通过吊绳吊设于所述浮力舱体的下方;拉力传感器,被配置为获取所述吊绳上的拉力;气体比例调节系统,用于调节所述浮力舱体之中的空气和轻型气体的比例;控制器,被配置为根据所述拉力传感器获得的拉力值确定总载重,基于所述总载重控制所述气体比例调节系统调节所述浮力舱体之中的气体比例,以使得所述浮力舱体提供的浮力与所述总载重相平衡。
