Visual Analysis of Emergency Communication Research Based on Scientific Knowledge Graph

Emergency communication is an important component of the emergency system and one of the key infrastructures for national emergency support, playing an increasingly important role in emergency management. This paper takes 1525 articles collected by CNKI from 2003 to 2023 as the data source, and with the help of CiteSpace6.2, conducts visual analysis on research topics, author cooperation, institutional cooperation, keywords, burst words, and time-series maps. The research results show that China's research on the field of "emergency communication" mainly focuses on emergency communication systems, emergency communication support, satellite communication, emergency communication networks, emergency communication technology, electric power emergency communication, railway emergency communication, unmanned aerial vehicles, and command systems, etc. The core authors are Wang Haitao, Chen Libin, Xu Zhengfei, Sun Shudong, Fei Wenliang, etc., and the research institutions are concentrated in Beijing University of Posts and Telecommunications, PLA University of Science and Technology School of Communications Engineering, Chongqing University of Posts and Telecommunications, China Electronics Technology Group Corporation No.54 Research Institute, Ministry of Industry and Information Technology Telecommunication Research Institute Communication Standards Research Institute, etc. Both author collaboration and institutional cooperation network are relatively loose. The core keywords in the research field include "emergency communication", "satellite communication", "application", "firefighting", "UAV", "shortwave communication", "emergency", "railway", "communication technology", "emergency events", with research hotspots focusing on "UAV", "firefighting rescue", "firefighting", "application", "satellite".
