DAC-3HGPEx
Ex-proof Strong Motion Seismic Monitoring with GPRS
Software Specification
Calculated parameters
:
PGA, PGV, Iax, CAV, CAV5, Sa, Sv, Sd, SI
Calculated for all 3 axis (x,y,z).
Filter
:
12 Hz. Low Pas Filter.
Trigger levels
:
Can be set for all calculated parameter.
Relay outputs
:
First relay is configured by the user as a combination of trigger levels for all calculated parameters other 4 relays are set for fault conditions.
Earthquake
:
When earthquake is detected relay 1 is activated. Acceleration values and calculated parameters before trigger (20 seconds) and after trigger (180 seconds) are saved into the internal memory. On same points (20s, 40s,.....180 sec) calculated parameters are sent by SMS (short message) to pre-saved telephone numbers.
