<p>The invention provides an elevator emergency power supply system which receives and supplies power through other components on a power network with a power generation device, thereby ensuring running of the elevator to a refuge storeyeven if the electricity is gone. The elevator emergency power supply system is configured in such a manner that a plurality of components (A, B...) of the elevator are capable supplying and receiving power for/from each other through an electric network (1), wherein the components (A, B...) includes an elevator operation control unit (5), a power distribution device (3), a normal power supply (2), an emergency power supply (7), and a power controller (4). The power distribution device (3) sends power supply request to other components when the normal power supply (2) is cut off and the electricity in the emergency power supply (7) is below a certain level, and feeds the power received from other component to the elevator operation control unit (5) via the power controller (4).</p> |
