Observation and research of multipoint infrasonic signals based on the embedded collection system

摘要：

To realize the observation of the multipoint infrasonic signals and solve the orientation of the infrasonic signals, the embedded ARM9 system of infrasound signal collection and network transport is designed. It is sure to get synchronously the infrasonic data of multipoint using GPS module. And it offers the pledge that fix on the epicenter through computing the time value. By actual observation in cycle, it is proved that the system has a good capability and runs reliably.
