民用轻小型无人机检测认证现状及铁路场景需求分析OA

To address the problem of insufficient coverage of professional scenarios including railways in existing standards,this paper developed a detection and certification framework adapted to railway environments.Taking the detection and certification system for civilian light and small unmanned aerial vehicles as the research object and focusing on the special requirements of railway inspection scenarios,this paper sorted out and analyzed Chinese and international standards and found significant gaps in the key requirements for railway scenarios:the lack of flight control stability tests under the strong electromagnetic environment of overhead contact lines and the absence of adaptability test methods for complex meteorological conditions such as high wind and rain in mountainous areas.By analyzing the special requirements of railway inspection for unmanned aerial vehicles and combining with practical experience from industry-specific standards in power grids,agriculture,and other industries,this paper proposed a two-tier inspection system of"general indicators+railway-specific indicators".The general tier retained universal indicators such as reliability and power and energy performance to ensure basic safety;the railway-specific tier added characteristic indicators including electromagnetic immunity of overhead contact lines and flight stability in wind and rain environments.The research results show that the established scenario-specific detection and certification system can effectively make up for the insufficient adaptability of existing standards to railway environments and provide technical support for the safe application of unmanned aerial vehicles in scenarios including railway bridge inspection and condition detection of overhead contact lines.
