近几年来国内无人机行业发展迅猛,一些单位都在尝试应用这种新设备。从高架梁底及支座巡视的研发应用角度,分析行业使用需求及可行性,阐述了高架梁底及支座巡视必备的几个关键技术,提出的一些新概念供商榷讨论。所述无人机仅对高架梁底及支座巡视专用的多旋翼飞行器而言。 In recent years, the domestic UAV industry has developed rapidly, some units are trying to apply this new equipment. From the perspective of the research and development of the elevated girder bottom and its supporting inspection, the author analyzes the requirements and feasibility of the industrial use, and elaborates on some key technologies necessary for the inspection of the elevated girder bottom and bearings. Some new concepts are proposed for discussion. The UAVs are only valid for elevated beam floors and multi-rotor aircraft dedicated to stand-by visits.
