Research and test on China high-speed railway earthquake early-warning system

The urgent development target of the China high-speed railway earthquake early-warning system (CRES) is analyzed, and the latest progress on the research and test verification are introduced in this article. At the same time, the research target and early-warning methods are described. Based on the breakthrough of P wave early-warning method and earthquake emergency treatment method, the reasonability of CRES has been verified by laboratory experiment, and field tests on Fuxia high speed railway (Fuzhou-Xiamen), Chengguan high speed railway (Chengdu-Guanxian), and Daxi high speed railway (Datong-Xian), as well as by the field experience about natural earthquake. The results show that its functionality and performance can meet the corresponding requirements, and that the stage target is reached. At last, the development direction is proposed.
