2)Wuhan Base of Institute of Crustal Dynamics, CEA, Wuhan 430071
Abstract A ZigBeebased seismic switch is proposed, which is emplaced in or outside some large buildings, and the seismic acceleration can be realtime collected.If Peak Ground Acceleration (PGA)or Cumulative Absolute Velocity ( CAV)exceeds the set threshold, the switch will give a alarm command via ZigBee wireless network to cut off the power, gas and other dangerous sources in order to avoid secondary disasters.
Key words :
ZigBee protocol
violent vibration
seismic switch
Peak Ground Acceleration (PGA)
Cumulative Absolute Velocity ( CAV)
