Abstract
An exemplary building sway operation system (10) for an elevator includes an acceleration sensor (11), and a data receiving unit (12) for receiving a sensor output from the acceleration sensor (11). The acceleration sensor (11) is designed to be mounted on a movable mass (6) of an active vibration control device (5) for a building, in order to detect the reciprocating motion of the movable mass (6) of the active vibration control device (5) responsive to the occurrence of earthquakes or strong winds.
Claims5
A building sway operation system for an elevator comprising:
- an acceleration sensor;
- and
- a data receiving unit for receiving a sensor output from the acceleration sensor,
- wherein the acceleration sensor is mounted on a movable mass of an active vibration control device for a building;
- wherein the data receiving unit is configured to calculate a moving distance of the building sway per unit time from the sensor output from the acceleration sensor, and calculate an amplitude value of the building sway from the moving distance of the building sway per unit time without detecting sway of the building.
