In order to solve the technical difficulties of improving the stability and reliability of professional software and hardware for domestic earthquake early warning,insufficient train installation testing,and to reduce the risk of earthquake early warning system operation,a specialized Chinese earthquake early warning technology testing platform has been constructed. The platform consists of two major test systems,software and hardware,which defined the test methods,test cases,test process and evaluation index. The platform has functional modules such as online functional testing,offline backtracking testing,early warning information testing and information security testing. Through systematic testing and comprehensive evaluation of the test results,it can provide scientific basis for the improvement and upgrade of professional software and hardware for earthquake early warning,and build a strong security line for earthquake early warning system.
