China is currently at the initial stage of comprehensively building a strong civil aviation power in various fields.Construction of smart airport plays a crucial role in implementing the strategy of technological innovation in civil aviation and achieving the transformation towards high-quality development of civil aviation.By reviewing relevant literature,it is found that the research on smart airport has undergone three evolutionary stages:inception(2003-2011),development(2012-2017),and acceleration(2018-2022).The research involves three themes:service,technology,and operation,which encompasses the entire process of airport activities.Due to the increasing research in recent years on composite designs supported by multiple interconnected technologies,"Digital Twins"and"Four-type Airport"have emerged as current research hotspots.Looking ahead to future research on smart airports,it is essential to dare to innovate theoretically,emphasize the practical value of research,and conduct continuous and in-depth studies.
