Research on Technology Trend for Civil Aviation Safety based on Patent Big Data Analysis

Safety is the bottom line and an insurmountable red line of the civil aviation operation. The development of civil aviation safety technology should not only combine the national conditions and civil aviation characteristics of each country, but also constantly broaden the perspective and absorb the advanced practices of the world. Therefore, it is very important to analysis the technology frontier and development trend in the field of global civil aviation safety. This study systematically and comprehensively analyzes and studies the field of civil aviation safety technology based on patent big data method. The research shows that the field of security technology is still in a period of rapid development, the number of patent applications in related directions is increasing, the scope of technology involved is becoming wider and wider, and the research methods present a trend of cross-border integration. Combined with patent retrieval and big data analysis conclusion, this paper analyzes the application status and technology development status of civil aviation safety technology patent, reveals the main technology distribution state and technology development direction hidden behind big data, and provides a reference for civil aviation safety-related enterprises, scientific research institutions, and government departments to understand the industry development trend and policy formulation.
