【摘要】 本文首先针对喷药无人机技术绘制专利地图,从发展趋势、重点技术领域、专利区域分布、优势机构、高引专利及失效专利等方面展开态势研究,为喷药无人机产业和技术的进一步发展提供情报支撑。研究结果表明,喷药无人机技术从1994年开始真正发展,专利申请量总体呈现快速增长,而且这一趋势延续至今。喷药系统、飞行平台和飞控系统是该领域的重点研发技术。中国近年来对于喷药无人机技术的研发热情高涨,申请有大量相关专利,但专利质量相对日本较低,核心专利缺失,技术水平还有待进一步提高。基于此,笔者从政府和企业两个层面提出了中国进一步发展喷药无人机技术的对策建议。更多还原

【Abstract】 In this paper,based on the patent map of agricultural spraying unmanned aerial vehicle(UAV)related technologies,the development status is investigated from several aspects,including development trend,key technology fields,regional distribution,rival agencies,highly cited patents and expired patents,to provide intelligence support for further development of agricultural spraying UAV industry and technologies by related government,companies,universities and research institutes.Research results indicate that agricultural spraying UAV related technologies began a rapid development around 1994 and up to now.Spraying system,flying platform and flight control system are key technologies of R&D.China has great R&D enthusiasm towards agricultural spraying UAV related technologies in recent years,and has applied a large number of patents.However,compared to Japan,the patent quality of China is a bit lower and China lacks core patents.Thus,the techonological level of China in agricultural spraying UAV field needs further improvement.Moreover,countermeasures and suggestions are presented for the development of agricultural spraying UAV in China from government level and company level.更多还原
