<P>PROBLEM TO BE SOLVED: To provide an earthquake sensing device for an elevator, of which detection sensitivity is hardly reduced, even if the earthquake sensing device is installed in a tilted manner. <P>SOLUTION: The earthquake sensing device 1 for an elevator, having an acceleration sensor 10s for sensing a quake of a building comprises: an angle calculation unit 21 for detecting a gravity acceleration value of a component accelerated by gravity by the acceleration sensor 10s in a state in which the earthquake sensing device 1 is installed, and determining an inclination angle θs of the acceleration sensor 10s from a reference vertical plane based on a predetermined reference gravity acceleration value and the detected gravity acceleration value; a memory unit 22 for storing the inclination angle; and a correction unit 24 for correcting the detected acceleration value based on the inclination angle θs stored in the memory unit 22, when the acceleration sensor 10s detects an earthquake. <P>COPYRIGHT: (C)2012,JPO&INPIT |
