摘要: An improved seismic alarm system designed to alarm users of an upcoming seismic event and other natural disasters, and aid victims' survival after an earthquake. The seismic alarm system includes an accelerometer, a controller, an acoustic-to-electric transducer for acoustic pattern detection, and RF module to receive emergency radio signals. The alarm system has central controlling unit that sets off an alarm after processing signals from several module and components: accelerometer detects seismic P wave acceleration changes for early earthquake detection; acoustic-to-electric transducer detects human acoustics or predetermined acoustic patterns, then initiates an alarm that brings rescue attention to survivors; RF module is tuned to receive emergency radio signals.
