Abstract: 【 Purpose/significance】 Reveal the core technologies in the field of smart emergency response based on the development sta⁃ tus of smart emergency technology, and rely on the technical correlation analysis to achieve high-quality development of smart emer⁃ gency response.【 Method/process】 Take the Innojoy search platform as the sample source of patent data related to smart emergency, comprehensively use LDA model, Word2Vec model and TextRank algorithm to determine relevant topics and explore the distribution of subject words, and use wordcloud and ROSTCM6 to achieve technical hotspot analysis and technical association analysis of patent abstracts. 【Result/conclusion】 Smart emergency response technology is now in the early stage of maturity; patent themes can be di⁃ vided into nine categories, including navigation positioning technology, emergency lighting technology and automatic alarm technology and so on. In the future, by promoting multi technology integration, multi module development, multi sector linkage and multi terminal cooperation, smart emergency technology will further enhance the ability to defend against safety accidents.【 Innovation/limitation】 It is a big deal that Innojoy's patent database only contains domestic patent data, and the scope of research samples in subsequent re⁃ search will expand the scope of domestic and foreign papers, reports and other relevant data.
