IMV Seismic and Health Monitoring System

”PROTECT" from second disaster, and "MONITOR" health of constructions


【Seismic Monitoring System】
Detect earthquake happens, output alarm for evacuation, and stop operation of machinery and facility. Also controlling alarm level with intensity and it makes possible to operate only on necessary occasion.
【Long period vibration monitoring system】
A new acceleration sensor mobile supports enhanced applications, including measurement of long-period ground motion and health monitoring of large structures.

Solution Illustrated


Giving evacuation instructions and stopping the facilities in the event of an earthquake have been mostly human-operated, which often resulted in inadequate response to the disasters. Also, the conventional drop-ball type seismographs do not allow the sensitivity settings to be changed after installation. Therefore, the false alarm and/or detection failure have been inevitable at some level. In addition, since the accurate seismograph equipped with the oscillatory waveform recording function requires specialized agencies for its operation, the visual check at the actual site was the only way to assess the detailed situation.  Therefore, the development of a new digital seismograph that is robust and easy to handle is needed to solve those existing issues listed above.

Exposition of the Solution

[Seismic Monitoring System]
It makes prompt announcements to the area and vicinity, conduct safety shutdown of the equipment, and shut off gas and water valves on detecting the earthquake in order to limit the damage and prevent the secondary disasters.

[Long period vibration monitoring system]
Assess the situations at normal times and post-disaster by checking the seismic isolation or seismic resistance of the large structures, and recording vibration waveforms caused by the earthquake or other factors.
