Abstract

The invention discloses an earthquake early warning system and earthquake parameter acquisition method based on an accelerated velocity sensor, and belongs to the technical field of earthquake early warning. The system includes a control device and a plurality of detection devices, and each detection device includes three detection units and data processing units disposed near the three detectionunits. The control device receives earthquake information sent by each data processing unit, adaptively selects several target detection devices according to preset rules, and ultimately determines earthquake parameters based on the earthquake information sent by the selected target detection devices, the detection units do not need to transmit a large amount of original earthquake data to the control device in real time, the delay problem caused by package and network transmission of long-distance real-time earthquake data is alleviated, the method is beneficial to improving the accuracy of early warning information in consideration of the limitation of early warning time, and meanwhile the distances arranged between the adjacent detection devices and adjacent detection units are relatively close to each other, which is beneficial for quickly gathering earthquake events, thereby increasing the early warning time.

Description

technical field [0001] The invention relates to the technical field of earthquake early warning, in particular to an earthquake early warning system based on an acceleration sensor and a method for acquiring earthquake parameters. Background technique [0002] The principle of earthquake early warning is based on the fact that the propagation velocity of electromagnetic waves is much greater than that of seismic waves, and the propagation velocity of seismic longitudinal waves (P waves) is faster than that of shear waves (S waves) and surface waves. Before cities or major projects, quickly obtain earthquake-related information, and issue earthquake warnings to potential damage areas in time, so that emergency measures can be taken in time to reduce possible losses caused by earthquakes. Therefore, the effect of earthquake early warning is directly related to whether people can take reasonable emergency measures in time to reduce earthquake damage as much as possible after re...
