Abstract:
     This invention relates to a vibration feature sensor. With space navigation and satellite time service function, it comprises an acceleration vibration pickup, a waveform recorder, a real-time process chip, a protective shell, an A/D circuit board to convert the acceleration signal acquired by the vibration pickup into digital signal and input into the process chip, and a GPS antenna and signal process unit to take space position and time service according to the satellite signal from the antenna and process the signal for earthquake decision by the preset threshold as well as outputting command signal. This invention has high precision and reliability.
