Research Of Earthquake Early Warning System

Earthquake is one of the worst natural disasters the human faces. The purpose of this design is to study and propose a solution establishing a timely, reliable and efficient earthquake early warning system,and the overall system solution is tested. In this paper, the earthquake early warning system is studied and designed, including the seismic zone distribution and characteristics, the monitoring devices of earthquake monitoring stations, the distribution and spacing of earthquake monitoring stations, the disposal of the central monitoring station for earthquake early warning information and the voice alarm and sound and light alarm from alarm receiver. Among them, the technical problems needing to resolve include: the reliability of the information from the monitoring site, the conflict resolution in early-warning information transmission, the error alarm resolution in earthquake information processing center, the accuracy of receiving information in each receiving stations, the timely and validity of alarm system and so on.In this paper, through the theory study about earthquake early warning system, with the professional characteristics, the earthquake early warning test system are designed and all the technical problems needing to resolve is achieved through the test system. The test result meets the timely , reliability and validity requirements of earthquake early warning system.
