Description

technical field [0001] The invention relates to the technical field of earthquake early warning, in particular to an intelligent autonomous networked earthquake early warning equipment and method. Background technique [0002] Earthquake Early Warning System (EEWs) refers to relying on the seismic network near the potential epicenter to quickly estimate the location, scope of influence, and degree of earthquake damage in the shortest time after the earthquake, before the destructive S-wave and surface wave reach the early-warning area. A real-time earthquake information processing system that issues warnings. As one of the means to effectively mitigate earthquake disasters, the earthquake early warning system requires that it can provide reliable early warning information of earthquake parameters for the early warning area in the shortest time, so it has high requirements for effectiveness and reliability. [0003] However, to provide more reliable earthquake parameters, th...

Problems solved by technology

[0003] However, to provide more reliable earthquake parameters, the earthquake early warning system needs longer time seismic data and more station measurement data. However, with the sharp increase in data volume, it will put pressure on the communication network and data processing center. It will cause network congestion and failure and increase the overall data delay of the system, thereby affecting the effectiveness of the system

In addition, the transmission network that relies on fixed communication base stations or gateways, after a major earthquake damages the base stations or gateways, the data of the stations cannot be transmitted, causing the entire system to be paralyzed

However, the earthquake early warning system relies on a single data processing center, and there is a risk that the entire system cannot operate due to computing crashes or damage from major earthquakes.
