Development on Seismic Sensor System with MEMS Technology for Elevator’s Seismic Condition

A large amount of elevators ruined in seismic events since sudden vibrations are bursting when elevator’s cars or counterweights are running. To solve this practical problem, this paper prospered a seismic sensor system with MEMS technology specializing for elevators. The fatal parts are discussed detailed including hardware design consideration, software improvement of sensor accuracy and seismic evaluation algorithm. Finally, two parts of experiments about P-wave and S-wave were verified successfully. To some extents, it’s reliable, suitable and affordable for domestic elevator’s safety on earthquake abrupt occurrence.
