Embodiment Construction
[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings and the following embodiments.
[0067] When the earthquake early warning processing system is working, it obtains the real-time seismic waveform data of the seismic station, and the seismic waveform data can obtain real-time data stream from the data collector of the seismic station through the real-time data stream service (SSS for short), so as to realize the real-time data stream of the station transmission, collection, forwarding, warehousing, etc.) to the earthquake early warning processing system, and the earthquake early warning processing system analyzes the seismic waveform and issues earthquake early warning information. The earthquake early warning processing system to be evaluated (hereinafter referred to as the system to be evaluated) transmits the data in the system through the Active MQ message server, and the embodiment of the application analyze...

The invention provides an evaluation method for a regional earthquake early warning system. The method comprises the following steps: acquiring an evaluation time point; obtaining a processing result of a to-be-evaluated system on the at least one earthquake early warning event at the evaluation time point; according to the processing result of the to-be-evaluated system on the at least one earthquake early warning event at the evaluation time point, obtaining a weight coefficient of the processing result of the to-be-evaluated system on the at least one earthquake early warning event at each evaluation time point; acquiring an early-warning positioning evaluation value, an early-warning magnitude evaluation value and an early-warning intensity evaluation value of the to-be-evaluated system for the processing result of the at least one earthquake early-warning event; according to the weight coefficient, the early-warning positioning evaluation value, the early-warning magnitude evaluation value and the early-warning intensity evaluation value of the to-be-evaluated system for the processing result of the at least one earthquake early-warning event, obtaining a comprehensive evaluation value of the to-be-evaluated system for the processing result of the at least one earthquake early-warning event; and evaluating the to-be-evaluated system according to the comprehensive evaluation value.
Description
technical field [0001] The invention belongs to the field of earthquake early warning, in particular to an evaluation method and evaluation system for a regional earthquake early warning system. Background technique [0002] Facing the complex and severe earthquake situation, how to effectively reduce the impact of earthquake disasters and reduce casualties during the occurrence of destructive earthquakes is an urgent problem that we need to solve. Earthquake early warning technology itself, as a worldwide problem, has stricter requirements on the real-time performance of earthquake alarm and alarm handling. At present, many countries and regions have completed or are building earthquake early warning systems. The earthquake early warning system is extremely important to the accuracy of earthquake early warning. Therefore, it is necessary to provide an earthquake early warning evaluation method in order to fully grasp its ability to deal with different magnitude ranges and ...
