Fast Generation Algorithm for Emergency Disposal Information in Earthquake Early Warning System for High Speed Railway
摘要
Abstract
Based on the structure and function of the earthquake early warning and monitoring system for high speed railway,a fast generation algorithm was proposed for the emergency disposal information in earthquake early warning system for high speed railway.The curve fitting method was used to establish the curve equation of high speed railway line in plane coordinate system.Based on the energy attenuation equation of ground motion,the circular curve equation of the earthquake affected range in plane coordinate system was established.Two equations were connected and solved,and the coordinate values of 2 intersection points of 2 curves were obtained.The coordinate values were transformed into longitude and latitude and then converted to kilometer scale,and the influence range of earthquake on high speed railway line was obtained.According to the principles of early warning and earthquake emergency disposal for high speed railway,the emergency disposal information of earthquake early warning for high speed railway was generated.The algorithm was applied to the tests and the field seismic experiments for the center system of railway administration in the earthquake early warning and monitoring of high speed railway.The maximum time for generating emergency disposal information was 40 ms,with an average of 18 and 27 ms respectively,which was far less than the required emergency disposal time of 100 ms for the center system of railway administration in "Interim Technical Conditions for High Speed Railway Earthquake Early Warning and Monitoring System",which verified the rationality and validity of the algorithm.关键词
