#$%^&*AU2018200925B120180419.pdf#####ABSTRACT The present invention discloses an earthquake warning system based on acceleration sensors and an earthquake parameter acquisition method, and belongs to the technical field of earthquake warning. The system comprises a control device and a plurality of detection devices, and each detection device comprises three detection units and a data processing unit closes to the three detection units. The control device receives earthquake information sent by each data processing unit, adaptively selects a plurality of target detection devices according to a preset rule and finally determines earthquake parameters based on the earthquake information sent by the selected target detection devices. The detection units do not need to transmit mass original earthquake data to the control device in real time, so that the problem of delay caused by long-distance real-time earthquake data packing and network transmission can be relieved, and the accuracy of warning information can be improved in consideration of the limitation of warning time. Moreover, the adjacent detection devices and the adjacent detection units are arranged relatively close to pick up earthquake events fast, so as to increase the warning time.
