Novel communication method for earthquake early warning

Abstract

The invention provides a novel communication method for earthquake early warning, which comprises the following steps that (1) the earthquake early warning critical information of each station is sampled and processed by an earthquake early warning critical information acquisition module installed on the station and is transmitted to an early warning center, and the response speed of earthquake early warning is effectively improved through reducing earthquake early warning transmission data transmitted by the station to the early warning center at the moment of the occurrence of an earthquake; (2) the earthquake early warning critical information acquisition module adopts a real-time online mode, does not transmit mobile seismic data at ordinary times and immediately transmits the earthquake early warning critical information generated by processing to the early warning center when mobile seismic waveforms are monitored so as to effectively relieve the transmission delay of the earthquake early warning critical information; and (3) the earthquake early warning critical information acquisition module adopts an earthquake early warning key data priority transmission and communication mode, i.e. the earthquake early warning critical information is transmitted firstly, and then other waveform data is transmitted after the end of seismic oscillation so as to improve the timeliness of the earthquake early warning critical information. The method is also applicable to intensity speed data transmission of the stations.

Description

Technical field [0001] The invention relates to the field of earthquake early warning, in particular to a new communication method based on the processing of earthquake early warning information at a station. Background technique [0002] Earthquake early warning (known as earthquake emergency report in Japan) is to issue early warning information to the target area before the destructive seismic wave reaches the target area, so that people can take emergency measures to reduce the loss of personnel and property. Therefore, the sooner the earthquake early warning information is received, the more lives and property of more people can be saved. It can be seen that improving the communication speed of earthquake early warning is very important. [0003] At present, the earthquake early warning monitoring instrument used in the earthquake early warning system developed by the Japan Earthquake Emergency Report and the earthquake early warning system being developed by the Fujian Provin...
